Acknowledgements The idea for this volume originated during the second annual conference of ESPAnet (the European Social Policy Analysis network) in Oxford in 2004. Each ESPAnet conference involves at least one stream of papers which deal with comparative methods in cross-national social policy analysis. In this context the editors of this volume discussed the current international debate about welfare reform and welfare state change, and the notion that the strong interest in this topic within the scientiﬁc community has not been matched by considerable academic progress. There are plenty of leitmotifs aimed at capturing the nature of welfare state change (or the lack of it), as well as competing accounts of how to explain policy reform. At the same time, there has been a noticeable paucity of how to empirically and systematically conceptualize, operationalize and measure change within and across welfare states. It is this ‘dependent variable problem’ and its various aspects which led the editors to invite international experts to a ‘thematic seminar’ in May 2005 at the University of Stirling, and subsequently to organize a panel on this topic at the 2005 ESPAnet conference in Fribourg, Switzerland. This book provides the results of these and subsequent discussions on the subject. It aims to reﬂect on a number of dimensions of the ‘dependent variable problem’ within comparative welfare state analysis, and to provide suggestions as to how to address and tackle it empirically. We are grateful to ESPAnet for providing the necessary fora for preliminary discussions, and to the Department of Applied Social Science, University of Stirling for hosting the above mentioned seminar in May 2005. We would like to thank Jacqueline Davidson for helping with its organization and all participants, and especially Frank Castles and Jane Lewis, for useful comments and advice. We owe thanks to our previous employers, i.e. the Universities of Stirling and Kent respectively, for enabling us to put the necessary time into editing this volume. We are indebted to all contributors for their eﬀorts and patience with us and our repeated requests for revision and reﬁnement. Finally we would like to thank Catherine Elgar for her interest in the original idea for this project and her continuous support throughout. Jochen Clasen Nico A. Siegel xii

PART I

The ‘dependent variable problem’ in comparative welfare state research

1. Comparative welfare state analysis and the ‘dependent variable problem’ Jochen Clasen and Nico A. Siegel INTRODUCTION Reforms of public pension schemes, health care systems and labour market programmes have been amongst the most salient political issues for some years. The reasons for governments to engage in welfare reform vary across countries, but generally include budgetary pressures and projected increases in spending on health care, social services and public pension systems. Economic internationalization and associated shifts in production and employment patterns have jointly contributed to new labour market risks, problems of long-term unemployment or labour market inactivity. Changing household formations as well as political forces, either of a domestic or a supranational nature (e.g., Europeanization), put additional pressures on policy makers to adapt existing forms of welfare state provision, and reinforce perceptions of welfare reform as a political topic which is likely to remain high on the public policy agenda for some time to come. Moreover, in terms of the political discourse, traditional left concepts favouring big welfare statism have become rather scarce. Instead of the public provision of social protection perceived as market restricting and correcting, current debates and new policies appear to present a shift towards market enabling principles. Within social science the notion of changing welfare states as a topic for comparative research is not new. In fact, it was the emergence and subsequent expansion of social protection until the 1970s which stimulated a large number of investigations into the causes for welfare state growth (e.g. Flora, 1987a) as well as processes of cross-national variation (e.g. Esping-Andersen, 1990). However, mirroring the more recent challenges to and current reform initiatives within advanced welfare states, the focus of research has shifted profoundly over the last decade. Whereas in the 1970s and 1980s most social scientists were studying the economic context, social 3

conﬁgurations and political coalitions and institutions which had enabled the massive expansion of the welfare state in the 20th century, nowadays they are investigating how governments are able to ‘impose losses’ without losing political power. An impressive number of books and articles have dealt with this ‘new politics of the welfare state’ (Pierson, 2001). Analysing the political logic of ‘welfare retrenchment’ and ‘blame avoidance’ has become a major research ﬁeld for political scientists. Many sociological accounts of welfare state change have shifted their focus too. The new risk conﬁgurations which seem to have emerged in the transition to postindustrial societies and which challenge welfare state arrangements that had been established in the context of old, traditional risk contexts of industrial societies have been at the centre of a number of recent research projects and books (Taylor-Gooby, 2004; Bonoli, 2005; Armingeon and Bonoli, 2006). Despite somewhat subject speciﬁc perspectives, authors across diﬀerent disciplines seem to agree that we are witnessing an era of considerable challenges to existing arrangements for social protection. Yet whereas some diagnose far reaching transformations, others identify incremental adjustments and stepwise recalibration. More generally, there is little consensus on either the nature of welfare state change or its scope. Indeed, despite a growing availability and comparability of relevant data, the body of comparative welfare state research cannot be described as resting on a widely shared empirical basis or common understanding about how much change there is, what drives change, or how the nature of change should be understood or conceptualized. This lack of progress in the description and explanation of welfare state change across countries and time is, we argue, at least to a considerable extent due to a ‘dependent variable’ problem, i.e. a noticeable absence of reﬂection on how to conceptualize, operationalize and measure change within welfare states. Of course, the kinds of problems we identify and discuss in this volume may be similar to those in many other areas of comparative studies in social sciences. Cross-national inquiries into processes of social dynamics, political regime change, social revolutions, or of structural changes in the economy, to name just a few examples, all face problems of conceptualization and operationalization. Comparative studies of welfare state change may thus not be a special case. Yet, as this volume aims to demonstrate, the ‘dependent variable problem’ deserves to be taken more seriously within comparative welfare state analysis than it has been to date. More than from a purely methodological perspective it raises important questions of theoretically guided concept building, and it has important implications for policy discourses too. With this volume we are hence taking a step back in order to focus on some of the most salient dependent variable problems in comparative

welfare state research – and on ways in which they might be addressed or even overcome. Ultimately such a step, we hope, will help to enable a more cumulative build-up of empirical evidence and contribute to constructive theoretical debates about the causes for welfare state change. Two points of clariﬁcation should be made. First, we acknowledge that a concentration on the welfare state as ‘dependent variable’ cannot overlook the point that welfare states can ﬁgure as important independent variables, too. For example, the size and institutional structure of national pension systems or health care programmes may inﬂuence the speed and direction of welfare reform. Equally, mature welfare states tend to be rather large employers in many countries. As Esping-Andersen has demonstrated in his ground breaking study of welfare regimes (Esping-Andersen, 1990), the welfare state itself is a major force stratifying societies and personal life contexts. Accounts of welfare state dynamics have thus to consider preferences and interests not only of relevant policy makers who are perceived as ‘exogenous political actors’ on the one hand and welfare state clientele on the other, but also possible vested interests of welfare state employees and the complex interplay of actors shaping the development of contemporary welfare arrangements. However, this volume does not intend to provide an all-encompassing manual on the challenges and pitfalls within the study of change and reform in modern welfare states. Adopting a less ambitious and more parsimonious approach, we deliberately restrict ourselves to discussions about diﬀerent aspects of the ‘dependent variable problem’. Put diﬀerently, our intention is to discuss why and in which ways the ‘dependent variable problem’ is relevant for comparative accounts of welfare state change, not only in terms of basic methodological or technical problems but also in terms of substantive and theoretical aspects within this ﬁeld of study. Second, we do not use the term ‘dependent variable’ in a narrow, technical or even exclusively statistical sense. Instead the term has been chosen in order to underline the general task of all chapters, i.e. to engage with the challenge of conceptualizing and measuring welfare state change – rather than contributing (further) to the debate about causes for change. Of course, it can be argued that the former cannot be discussed in isolation from the latter. Indeed, as Green-Pedersen points out in Chapter 2 of this volume, diﬀerent theoretical perspectives tend to favour diﬀerent types of dependent variables. For example, a focus on what Bonoli (2006; and Chapter 3 this volume) has referred to as ‘new social risks’ (such as single parenthood, having relatives in need of long-term care, possessing obsolete skills, insuﬃcient social insurance coverage), and the extent to which welfare states have responded to their emergence, would suggest certain types of concepts and indicators of change. Social spending as a central

parameter for assessing change might not be suitable for approaches which focus on gender related aspects of welfare states, or those which aim to test the impact of left parties on welfare state generosity. Instead, as it was not a goal of welfare state advocates to struggle for higher social spending per se (cf. Esping-Andersen, 1990) but to improve the degree of social protection in the context of market economies, composite indices of ‘de-commodiﬁcation’ (operationalized as a form of beneﬁt generosity) seem to oﬀer a more appropriate means for assessing the inﬂuence of prowelfare state advocates on policy making. In other words, as GreenPedersen argues in Chapter 2, the choice of a dependent variable should follow theoretical considerations.

THREE ASPECTS OF THE ‘DEPENDENT VARIABLE PROBLEM’ Collectively, subsequent chapters tackle three separate aspects of the ‘dependent variable problem’: questions of conceptualization, operationalization and measurement. As for the former, depending on analytical interest, the welfare state (or welfare regimes) might be regarded as an inappropriate unit of analysis since its individual components (transfer programmes, services) might diﬀer substantially in terms of the type of risk management, dominant actor constellations, and interdependencies with other policy ﬁelds, e.g. as integral parts of political economies (Hall and Soskice, 2001; Ebbinghaus and Manow, 2001). Over the last decade a growing number of authors have argued that the comparative analysis of the welfare state should be disaggregated to investigations into the dynamics of particular policy domains in order to be able to better capture variation both in terms of policy outcome (Huber and Stephens, 2001) as well as processes of reform (e.g. Ferrera and Rhodes, 2000b; Pierson, 2001). Of course, whether changes of or within welfare states are of interest reﬂects diﬀerent research questions and approaches. Conventionally and narrowly deﬁned, welfare state programmes consist of statutory beneﬁts and service provision (generally leaving aside education). More broadly deﬁned, the ‘welfare state’ can be conceptualized as all mechanisms which provide social protection against and redistribution of market mechanisms and outcomes. Hence the welfare state not only comprises transfers and services, but also tax expenditures, minimum wages, state regulation of labour and product markets, state recognition of collective bargaining and other interventions, all of which ‘disconnect or buﬀer income streams from market outcomes’ (Schwartz, 2003). As Giuliano Bonoli discusses in Chapter 3, the decision in favour of a broader or a more narrow boundary

of the term ‘welfare state’ is not merely a matter of perspective. It also determines the level of analytical abstraction and thus inﬂuences whether or not the explanatory power of diﬀerent theories of the welfare state can be assessed against each other. To put it diﬀerently: both the choice of analytical perspectives and of empirical indicators are shaped by (meta)theoretical considerations and they aﬀect central issues of descriptive and analytical inferences in comparative welfare state research. Following on from the more general aspects covered in this introduction as well as in Chapters 2 and 3, subsequent sections deal with indicators, measurement and concepts. Since it has ﬁgured so prominently within comparative welfare state analysis, each of the three chapters of Part II is devoted to the value of ‘social spending’ as a yardstick for measuring the size of the welfare state and to assessing its scope of change. Part III comprises three chapters which present alternative parameters of change which could be used instead of, or to complement, social spending, such as welfare state generosity and beneﬁt conditionality. Finally, Part IV addresses the usefulness and problems of some ‘big concepts’ which have been employed as leitmotifs in analyses aimed at capturing the nature of change in contemporary welfare states: ‘convergence’ (Julia O’Connor in Chapter 10), de-familization (Sigrid Leitner and Stephan Lessenich in Chapter 11), and ﬁnally, path dependence (Sven Jochem in Chapter 12).

SOCIAL SPENDING AND OTHER INDICATORS OF WELFARE STATE CHANGE The amount of money spent on social protection programmes has ﬁgured as a major indicator particularly within ‘variable oriented’ quantitative comparative studies of welfare state development. Improved and more comprehensive data sources (Castles and Obinger, 2006), disaggregated data at the level of individual social policy programmes (Castles, 2004), as well as more sophisticated statistical techniques (e.g. Kittel and Obinger, 2003) have contributed to the continuous popularity of social spending as a central parameter of studies of change or stability within, and convergence or divergence across, welfare states. Nevertheless, for some time now questions about the nature and appropriateness of social expenditure as the (only) ‘dependent variable’ for quantitative welfare state comparisons have been asked even by prominent scholars within this ﬁeld (e.g. Castles, 1994). More recently, the debate about the pitfalls of expenditure based welfare state accounts has been revitalized because analyses for the post-1980s era have produced more inconclusive results than studies which concentrated on the expansion of social expenditure in the 1960s and 1970s. Sensitivity

8

The ‘dependent variable problem’ in comparative welfare state research

towards the choice of statistical techniques, model speciﬁcations, and spending indicators contributed to this inconsistency. At a time when the OECD started to publish regular updates of probably the best source for social expenditure ﬁgures ever available for comparative welfare state research (the so-called ‘SOCX’, OECD Social Expenditure Database, see OECD, 2005a), critical voices were raised concerning the comparability of data across countries and time. Yet in most comparative studies, such issues tend to be ignored or neglected. Three chapters in this volume critically reassess the use of expenditure analysis in comparative welfare state research. In Chapter 4, Nico A. Siegel presents a general discussion of the use of expenditure data, illustrating the strengths and importance as well as problems of comparative inquiries which mainly (and sometimes exclusively) describe and analyse welfare state change in the light of levels of social spending. In Chapter 5, Johan De Deken and Bernhard Kittel focus on more speciﬁc problems. They compare the quality of spending data provided by major international agencies such as the OECD or EUROSTAT. Since deﬁnitions of national social policy programmes diﬀer across countries and time, researchers face severe problems when comparing expenditure dynamics. Whereas methodological innovations such as pooled time series analysis seem to oﬀer ever more sophisticated techniques of macroquantitative data analysis, the chapters by Siegel and De Deken and Kittel both demonstrate that research practice is plagued by basic (and some seemingly trivial) problems of data quality, comparability, and non-random measurement error of the dependent variable. Together, these issues generate knotty problems for cross-national studies. Consequently, comparative welfare state researchers run the risk of building their analytical inferences on rather shaky empirical foundations, i.e. on descriptive inferences which may inherently suﬀer from measurement bias and related issues of the dependent variable problem. The ﬁnal chapter of Part II deals with the comparative analysis of social expenditure and particularly its relationship to other indicators, such as welfare state generosity as an expression of ‘social rights’. As Olli Kangas and Joakim Palme demonstrate in Chapter 6, levels and changes of social expenditure are aﬀected by two major factors: the generosity of social rights (which is basically a direct consequence of political decisions aﬀecting beneﬁt levels and conditions of eligibility and entitlement) and levels of ‘structural need’ which reﬂect demographic and other socioeconomic factors. The authors argue that social expenditure data, particularly at the most aggregated level (‘total public social expenditure’), should not be used to infer changes in the generosity of social rights. In short, the categorical imperative of comparative research aimed at investigating

the extent of welfare state expansion or retrenchment, rather than analysing merely the change in ‘welfare eﬀorts’, is to move beyond a purely expenditure based and macroscopic perspective of the ‘welfare state’ and engage with more detailed accounts of changes and policies at the level of individual social policy programmes. Indeed, the complexity of advanced welfare states seems to make it tremendously diﬃcult to reduce major dynamics of change to just one or a few social policy indicators, and to explain the dynamics of change with a ‘catch all master theory’ (Siegel, 2002). The suggestion of complementing (or substituting) social expenditure with other indicators of change is the topic spanning the three chapters in Part III. A prominent alternative, also propagated by Kangas and Palme, are ‘social rights’, which are expressed as entitlement conditions (beneﬁt level and duration) and, often ignored, eligibility conditions. Lyle Scruggs has developed a new method and data source for quantitative measures of welfare state generosity. His innovative data set combines measures of several dimensions of welfare state ‘generosity’, covering core social policy programmes such as unemployment beneﬁts, public pensions, and child allowances for a time span of more than 30 years (1970–2001) for 18 OECD democracies. In Chapter 7, Scruggs thus illustrates how the empirical infrastructure of comparative welfare state research can be improved. His ﬁne grained instruments for measuring beneﬁt generosity provide surprising results and challenges, contesting the idea of clearly distinct and conventionally conceived welfare regimes. Moreover, his programme speciﬁc analysis suggests a certain extent of convergence since the 1980s while questioning the notion of welfare state resilience against cutbacks. In Chapter 8, Jochen Clasen and Daniel Clegg point out that many current reform initiatives are about the management and reallocation of risks across diﬀerent social groups and between the public and the private sphere. Even a ‘social rights’ based approach to studying welfare state change may thus miss a central aspect of change. All social rights are conditional and involve obligations on the part of beneﬁt claimants. In principle, changes in (various dimensions of) conditionality could thus be employed for measuring the scope of change within welfare state programmes which are often assumed, but rarely systematically investigated, as signalling paradigmatic shifts towards ‘enabling’ or ‘social investment’ states. Linking up with these two chapters of Part III, in Chapter 9, Jon Kvist employs empirical indicators of ‘generosity’, as well as two dimensions of conditionality, i.e. the ‘accessibility’ of transfer payments and the obligations imposed on beneﬁt claimants. However, he operationalizes indicators somewhat diﬀerently and makes use of one of the more recent methods in

comparative analysis, fuzzy-set methodology. Applying his analysis to unemployment insurance in seven countries, Kvist demonstrates that fuzzyset methodology provides a powerful tool for the identiﬁcation of social policy programmes shifting between ideal typical welfare state categories. In contrast to social expenditure based accounts of change, fuzzy sets, used for a comparative exploration of changes over time, not only oﬀer a more encompassing method of capturing multidimensional changes within individual welfare state programmes but also present a more ‘concept driven’, and therefore theory guided comparative method than the statistical analysis of spending accounts.

CONCEPTUALIZING CHANGE The ﬁnal part of this volume deals with macro conceptualizations of the nature of change within modern welfare states. As already referred to above, ‘retrenchment’ has become perhaps the most prominent concept within the comparative social policy analysis in recent years. Hinrichs and Kangas (2003: 574) pointed out that it was Paul Pierson (1994) who initiated what they call the ‘retrenchment business’ in comparative welfare state research, i.e. cross-national investigations into the causes for and political management of imposing losses within modern welfare states. However, Pierson’s theoretical interest in ways in which decision makers are able to ‘avoid blame’ (Weaver, 1986) has rarely been matched by reﬂections as to how to conceptualize and measure ‘retrenchment’ within or across welfare state programmes (Alber, 1996). However, similar criticisms can be made of many other concepts aimed at capturing the nature of at times diﬀerent types of welfare state change which have mushroomed lately. These include ‘re-commodiﬁcation’, ‘cost containment’, ‘recalibration’ (Pierson, 2001), ‘individualization’ and ‘de-familialization’ (Ostner, 2003; Leitner et al., 2004), or ‘residualisation’ (Powell, 2004). It is beyond the remit of Part IV of this volume to review the range of concepts and leitmotifs on change within contemporary welfare state research (Hobson et al., 2002, cover quite a few). Instead, as a way of illustrating the complexity, problems involved and usefulness of concepts which have been employed frequently in recent analyses, the three chapters of Part IV focus on ‘convergence’, ‘(de)-familization’, and ‘path dependence’ respectively. The question whether advanced welfare states are undergoing major convergent trends, or whether persistent diversity can be observed, has been at the heart of welfare state analysis for a long time. However, whereas the question of convergence or divergence in the 1960s ﬁgured most prominently in comparisons of economic systems (capitalism vs state socialism,

11

e.g., Pryor, 1968) and was linked to the so-called ‘end of ideology debate’, in the 1980s and 1990s the convergence-divergence question was raised in a diﬀerent context and closely coupled to the study of globalization, or more generally, economic and political denationalization. As Julia O’Connor’s contribution in Chapter 10 shows, the concept of convergence is related to general issues of globalization and Europeanization. Whereas new concepts and measures of convergence have been suggested by several authors during the last two decades, the question of developing and selecting appropriate indicators for the assessment of the various types of convergence remains a major challenge. The concept of ‘de-familization’ has gained a prominent position in contemporary analyses of welfare state change not least as a response to the concept of ‘de-commodiﬁcation’ (Esping-Andersen, 1990) which has been criticized as unduly focusing on the (expansion or retrenchment) of social rights arising from (male) paid work in the labour market, thereby ignoring the ‘familization’ of care work, which is largely done by women. ‘De-familization’ has been seen, as Sigrid Leitner and Stephan Lessenich argue, as a process of ‘unburdening the family’ (de facto, women) from care responsibilities by providing rights to payments for care which secure economic independence of the carer and her dependants, as well as access to paid work via, for example, the expansion of public services. However, the authors show that the concept is ‘multi faceted and complex’, involving ‘economic’ as well as ‘social’ independence, and must be perceived from two perspectives, the carer and the person who is cared for. By deconstructing the concept of ‘de-familization’ Leitner and Lessenich demonstrate that it can be employed as a ‘dependent variable’ in empirical comparative analysis, although its multidimensionality needs to be recognized. Finally, one of the most prominent concepts in the recent study of the political reform processes of welfare state changes is that of path dependence. The term has become somewhat of a catch-all theorem, often without clear conceptualization, let alone operationalization or measurement. It characterizes the logic of change as much as the nature (or process) of change. In Chapter 12, Sven Jochem not only provides a critical discussion of several dimensions of path dependence but also operationalizes the concept, which allows researchers to generate criteria for the categorization of welfare state reforms as path stabilizing or path deviating. In order to demonstrate that there are ways of solving the ‘dependent variable problem’ of specifying critical thresholds, Jochem discusses one of the areas of welfare state reform where path dependence is to be expected, i.e. pension reform. Similarly to Scruggs (Chapter 7), Clasen and Clegg (Chapter 8), and Kvist (Chapter 9), his analysis provides evidence against the notion that contemporary welfare states are locked in distinct

12

trajectories which tend to reinforce themselves. Given that even the ‘elephants of the welfare state’ are on the move (Hinrichs, 2001), it is hardly plausible to assume that the more lightweight welfare state programmes suﬀer from inertia. So, what are the lessons of these investigations into welfare state change and particular aspects of the dependent variable problem? For us, perhaps the most valuable point is the importance of investing in the theoretical and empirical infrastructure for comparative research. The development, upgrading and updating of this infrastructure might not be regarded as the most attractive academic endeavour given that it is time consuming and does not promise short-term gains or spectacular breakthroughs in scientiﬁc debates. However, we regard it as an essential long-term investment, building robust foundations for systematic empirical cross-national analysis. As the subsequent chapters demonstrate, real welfare state change is complex and diﬃcult to capture, especially in comparative analysis. This however, is rarely acknowledged within overly parsimonious or elegant models or ‘generalized’ theories. It thus seems worthwhile to go back to the roots of comparative research: conceptualizing, operationalizing and measuring the kind of changes which may transform democratic welfare capitalism around the globe.

2. More than data questions and methodological issues: theoretical conceptualization and the dependent variable ‘problem’ in the study of welfare reform Christoﬀer Green-Pedersen INTRODUCTION1 Studies of welfare state reform2 have been booming in recent years. Today the literature in the area oﬀers a large number of theoretical arguments on what, for instance, causes cross-national variation in the scope or degree of welfare reforms implemented in OECD countries. In the literature claims are made about the importance of party politics in diﬀerent versions (Ross, 2000a; Kitschelt, 2001; Green-Pedersen, 2002; Korpi and Palme, 2003; Allan and Scruggs, 2004), the role of political institutions (Bonoli, 2000; Swank, 2002a), political discourse (Cox, 2001; Schmidt, 2002) and economic pressures (Castles, 2001). However, the literature actually oﬀers very few established facts as to what factors or what combination of factors matter for cross-national variation in welfare state reform. One clear example is the continuation of the classical ‘does politics matter?’ debate. Some studies (Korpi and Palme, 2003; Allan and Scruggs, 2004) claim that politics still matters, or more precisely that social democratic parties in government matter, implementing less welfare state reform, especially retrenchment reforms, than centre-right governments. Other studies (Ross, 2000a; Green-Pedersen, 2002) argue the opposite, i.e. that social democratic governments introduce more rather than less retrenchment than rightwing governments, thereby reversing the classic ‘politics matters’ claim. Yet other studies (Castles, 2001; Huber and Stephens, 2001; Siegel, 2001; Kittel and Obinger, 2003) imply that politics does not matter any longer. In one way, the continuing disagreement is helpful since it keeps the scientiﬁc debate alive, but in another way it is also deplorable. After all, the role of party politics in welfare retrenchment and reforms is an empirical 13

14

The ‘dependent variable problem’ in comparative welfare state research

question to which welfare state research should be able to oﬀer fairly clear answers. So why are there conﬂicting answers to basic empirical questions such as ‘does politics matter?’ (and others, see below) in the central literature on welfare state reform? The argument proposed here is that this is partly caused by what I label the ‘dependent variable problem’ (GreenPedersen, 2004), i.e. the problem of what is meant by welfare state reform and how reforms can be measured. The chapter argues, ﬁrstly, that more attention needs to be paid to these questions in order to advance comparative welfare state research; secondly, it will outline some of the issues which the debate needs to address. The chapter ﬁrstly argues that the ‘dependent variable problem’ is as much a question of theoretical conceptualization as it is a question of empirical indicators. A clear theoretical deﬁnition of what one wants to measure is a necessary ﬁrst step before considering indicators. Secondly, a clear distinction has to be made between welfare state retrenchment and welfare state restructuring, with the former concept needing further reﬁnement from both an output and an outcome perspective. Finally, the chapter argues that the often emphasized distinction between quantitative and qualitative studies of welfare state reform is misplaced in the sense that both types of study should aim to make use of systematic empirical indicators, albeit not necessarily expenditure data. Only the combination of diﬀerent types of indicators will advance the study of welfare state reform and retrenchment in terms of answering basic empirical questions. Continuing Disagreement – the Literature on Welfare State Retrenchment As indicated, the literature on welfare state reform, especially retrenchment, is divided on the classical question ‘does politics matter?’. What lies behind this disagreement? It is noticeable that studies which challenge and reverse the traditional ‘politics matters’ argument, i.e. argue that social democratic governments tend to retrench welfare programmes more than centre-right governments, are based on studies of a few countries (Ross, 2002a; Green-Pedersen, 2002). Thus one explanation for the disagreement may simply be found in the number of countries studied which tended to be much higher in previous research which favoured the classic, i.e. socialdemocratic ‘politics matters’ proposition. However, recent research covering 18 OECD countries is divided too, with some studies concluding that politics does not matter anymore (Castles, 2001; Huber and Stephens, 2001; Kittel and Obinger, 2003) while others continue to subscribe to the classic ‘politics matters’ argument (Korpi and Palme, 2003; Allan and Scruggs, 2004). Further, in terms of statistical methods, apart from Castles (2002) all studies use a pooled time cross-sectional approach and still reach

Theoretical conceptualization and the dependent variable ‘problem’

15

diﬀerent conclusions (for a more detailed discussion, see Siegel, Chapter 4 in this volume). However, studies which argue that politics matters focus on trends in welfare generosity, using mainly beneﬁt replacement rates in selected welfare programmes. By contrast, investigations which claim that politics does not matter anymore focus on the development of social expenditure in relation to GDP. In other words, the answer to the question whether ‘politics matters’ depends on the dependent variable and how it is operationalized. There are other examples in the literature on recent welfare state reform. Based on a qualitative assessment, Anderson (2001) argues that the Swedish pension system was retrenched more than the unemployment scheme. Making use of the economic model applied by the Swedish Ministry of Finance, Lindbom (2005) concludes the opposite. Hacker (2002; 2004) argues that Pierson’s (1994) conclusion about continuity in the American welfare state is based on an exaggerated focus on active changes in formal welfare programmes, thereby ignoring changes in the societal context of welfare programmes. Thus, also in these cases the operational deﬁnition of the dependent variable seems to determine the conclusions. The examples above indicate that much more attention needs to be paid to the dependent variable within studies of welfare state reform. Following Kitschelt (2001) with regard to the disagreement on the dependent variable, Pierson (2001: 420) argues that ‘it is diﬃcult to exaggerate the obstacle this dissensus creates for comparative research . . ., it is impossible to seriously evaluate competing explanations when there is no agreement about the pattern of outcomes to be explained.’ Nevertheless, to date the issue has not been suﬃciently addressed in the literature, despite some notable exceptions. For example, Castles (2002) discusses how new opportunities for disaggregating social expenditure can ease some of the problems involved in using social spending as an indicator of welfare state development, while Allan and Scruggs (2004) also pay attention to the same issue. There is a lively debate, for example, on the usefulness of the pooled time series cross-sectional statistical approach (Kittel and Winner, 2005; Plümper et al., 2005). Such a discussion of statistical techniques is of course highly appropriate, but it is striking that this aspect receives more attention than the question of the appropriateness of the data that are analysed. Theoretical and Operational Deﬁnitions As a starting point for discussing these matters, a clear distinction between theoretical and operational deﬁnitions is crucial, i.e. between what one wants to measure and how one measures it. While this point is straightforward, it

16

The ‘dependent variable problem’ in comparative welfare state research

receives surprisingly little attention in the welfare state retrenchment literature. For instance, in his well known article on the new politics of the welfare state, Pierson (1996) argues that welfare state retrenchment is deﬁned as (1) signiﬁcant increases in the reliance on means-testing; (2) major transfers of responsibility to the private sector; (3) dramatic changes in beneﬁt and eligibility rules that signal a qualitative reform of a particular programme. This is a theoretical deﬁnition of retrenchment which leaves open the question about how to measure, for instance, ‘signiﬁcant increases in the reliance on means-testing’. Without such an operational deﬁnition, it becomes impossible for others to reproduce the ﬁndings. Exactly this presents a major weakness of many studies based on ‘qualitative assessment’, often lacking an operational deﬁnition that spells out how, and on the basis of which criteria, assessments were made, thereby diminishing their reliability signiﬁcantly. It is simply often diﬃcult for other researchers to arrive at the same conclusion when making similar assessments. At the same time, many other studies use social expenditure data without much discussion on the usefulness and appropriateness of the data. Reliability is rarely a problem here, but judging the validity of expenditure as a measure is impossible without a reﬂection of what one wants to measure.

WHAT TO MEASURE? THEORETICAL DEFINITIONS OF WELFARE STATE RETRENCHMENT Regarding the question of what one wants to measure, a couple of distinctions and delimitations are important. First, the welfare state may be viewed either from an output or from an outcome perspective. The output perspective regards the welfare state as a number of government programmes or policies, and welfare state reforms as changes to these outputs or programmes. This raises questions concerning the underlying assumption about what the welfare state is (see also Chapter 3 by Bonoli). The literature generally agrees on deﬁning the welfare state as social policy in a broad sense, i.e. including most cash transfers to households such as pensions, unemployment beneﬁts, child allowances and housing beneﬁts, and social services such as health care, child care, elder care and social housing. However, should educational policy be regarded as part of the welfare state too? What about macroeconomic policy? Adopting an outcome perspective the welfare state is viewed more from recipients’ perspective, as a government’s commitment to, for instance, minimizing inequality or maintaining full employment. In other words,

when looking at welfare state reform, the starting point would be to examine how outcomes such as inequality or replacement rates have developed. Developments in these outcomes are of course inﬂuenced by outputs or policies, but other factors are relevant too, such as changes in the extent of social need. In short, it is imperative to reﬂect on the concept of ‘welfare state’ since there is a diﬀerence in adopting an outcome as distinct from an output perspective. Second, it is important to distinguish between two types of welfare state reform, namely retrenchment on the one hand and restructuring or institutional change on the other. The former refers to changes which cut back or reduce social entitlements by, for example, reducing beneﬁt levels, tightening eligibility rules or shortening entitlement periods. The latter refers to changes to the institutional rules surrounding a scheme. These can be changes in the administration or the funding of beneﬁts, but also shifts in the principles which govern the calculation of beneﬁts, for instance changes in the scope or type of means-testing (cf. Clasen and van Oorschot, 2002). This distinction is important because the evaluation of certain changes to a programme is highly dependent on the perspective adopted. A reduction of say 5 per cent in beneﬁt level is clearly a form of retrenchment. But it is not necessarily an institutional change. On the other hand, ﬁnancing or organizational structures may be altered without aﬀecting beneﬁt generosity, just as principles may be changed without implying retrenchment. Imagine, for instance, a ﬂat-rate pension scheme which becomes supplemented by a highly selective pension top-up. Such a change implies an institutional alteration, but clearly not a case of retrenchment. To provide a concrete example, the Swedish pension reform in the ﬁrst half of the 1990s clearly represented a major form of restructuring. However, the degree of retrenchment is much less clear, partly because the new pension system automatically adjusts pensions downward if life expectancy increases (cf. Anderson, 2001; Lindbom, 2005). It is the future development of life expectancy therefore which will partly determine the retrenchment eﬀects of the reform. When focusing on retrenchment, the distinction between output and outcome perspectives becomes highly important. From the output perspective, retrenchment is ‘negative’ since beneﬁts are reduced or eligibility rules tightened as suggested above. From the outcome perspective, one would focus on for instance rising inequality, which is seen as a retrenchment of the political commitment to minimizing inequality (cf. Clayton and Pontusson, 1998). Rising inequality may be the result of programme retrenchment, but could also be the result of changes to the tax system or wage inequality and requires a much broader perspective on the welfare state than the output perspective. As mentioned, Hacker (2002; 2004) has

18

The ‘dependent variable problem’ in comparative welfare state research

shown how the development of the US welfare state looks very diﬀerent once an outcome perspective is applied, in contrast to Pierson’s (1994) output perspective. When discussing diﬀerent theoretical deﬁnitions, it is important to be aware that no deﬁnitions are better or worse than others per se. Which theoretical deﬁnition of retrenchment should be adopted depends on the overall theoretical question of interest. For example, if it is a government’s ability to implement unpopular policies (as in Pierson, 1994, for example) then an output deﬁnition is clearly the most logical choice since the overarching interest are policy measures which governments are politically able to carry through, rather than eﬀects on recipients. However, if the latter is the theoretical focus, an outcome deﬁnition seems more useful. The same point applies to institutional aspects of programmes. Following Esping-Andersen (1990), it has become fairly common to focus on the question of selectivity vs. universalism, as Pierson’s (1996) deﬁnition above shows. However, it is often ignored that the focus on the institutional aspect of welfare programmes stems from power resources theory and the need of the working class to secure broad political support for the welfare state. If this theoretical perspective is not applied, it is far from obvious why universalism should ﬁgure as a focus in welfare state research and not other institutional aspects. In sum, there are several ways to deﬁne welfare state reform theoretically and the choice depends on the broader theoretical perspective adopted. There is no such thing as reform per se, and thus no particular deﬁnition which would capture the essence of reform. The crucial point is to pay attention to the question of theoretical deﬁnitions, how the latter are linked to the broader theoretical perspective underlying a particular study, and how this aﬀects the choice of measurement. Discussing measurement issues without knowing what one wants to measure in the ﬁrst place is problematic and in this sense the dependent variable ‘problem’ concerns questions of theoretical deﬁnition or conceptualization as much as methodological and technical questions.

OPERATIONAL DEFINITIONS Before discussing diﬀerent types of measurements, it is worth taking up the issue of quantitative vs qualitative research. To some extent the literature on welfare reform reﬂects a divide between studies of a few countries, which often focus more on processes and politics related to the reform and less on measuring reforms (e.g. Bonoli, 2000: Timonen, 2003), and studies of all OECD countries which apply social

expenditure data. The latter tend to omit any discussion of the advantages and limitations of using these data. Such a divide is also evident in several prominent studies of welfare retrenchment such as Huber and Stephens (2001) and Swank (2002a), which combine statistical analysis of expenditure data with case studies of selected countries. Measurement questions seem to relate mainly to expenditure data. One is thus left with the impression of having to choose between two evils: either using expenditure data, which, as will be argued below (see also De Deken and Kittel’s contribution to this volume), incorporates several problems, or conducting case studies without much reﬂection on the measurement of the scope of reforms implemented (see Jochem, Chapter 12, this volume). The latter often makes case studies vulnerable to ‘fuzzy judgments’, as Alber (1996) critically noted. However, as argued by King et al. (1994) or Brady and Collier (2004), there is no fundamental diﬀerence between quantitative and qualitative research. Both share the same scientiﬁc ambition and the same basic standards for research. Thus, discussing operational deﬁnitions and diﬀerent types of indicators should essentially be a reﬂection of the pros and cons of diﬀerent ways of measuring theoretical variables. In other words, the issue at stake here is the validity and reliability of diﬀerent measures or indicators, not one of diﬀerent research aspirations or one of numbers vs judgments. For good reasons, social expenditure is by far the most common measurement in studies of welfare state retrenchment and of welfare state expansion. Data are easily available for all relevant countries and cover almost all relevant welfare state programmes, although data on social service expenditure remain somewhat of a problem (see Huber and Stephens, 2001). Furthermore, social expenditure provides a summary measure of diﬀerent aspects of programmes. How else would it be possible, for example, to add together changes in beneﬁt levels, eligibility rules and beneﬁt duration? However, there are at least four sets of problems attached to using expenditure data. Firstly, in order to make ﬁgures cross-nationally comparable, calculating social expenditure as a percentage of GDP is most common. The problem is, of course, that the measure is then also aﬀected by the development of GDP (see also Scruggs, Chapter 7, this volume; Clayton and Pontusson, 1998). Secondly, expenditures on certain transfer programmes, especially unemployment beneﬁts, are strongly inﬂuenced by the state of the economy. A government can easily limit unemployment beneﬁt levels and at the same time experience rising expenditure due to higher unemployment. This problem is well recognized, and Castles (2002) has suggested leaving unemployment beneﬁts out of analyses based on expenditure data, whereas Siegel (2001) has adjusted data by keeping the number of recipients constant. Still, the problem with such strategies is the loss of information on the

20

The ‘dependent variable problem’ in comparative welfare state research

development of the programmes. Changes in the number of unemployed, for example, are inﬂuenced not simply by the level of unemployment, but also by eligibility and entitlement (beneﬁt period) rules. Thirdly, there is a ‘time-lag’ problem (Pierson, 1994: 14). This refers to the fact that many retrenchment reforms are designed to have a gradual rather than immediate eﬀect. Consequently, many legislative changes are not immediately reﬂected in expenditure data. The relevance of this problem varies, but with regard to pension systems it is a very serious caveat since pension reforms are typically designed to take eﬀect in the long run. The expenditure eﬀects of many pension reforms which were implemented in OECD countries in recent years will become visible only gradually over the next decades. Fourthly, an investigation into reforms in welfare services, rather than transfers, generates questions about the usefulness of expenditure data from the perspective of people receiving such services. One clear example of this is health care expenditure. Does the fact that a country spends more on health care imply a better health care system or just one which is more ineﬃcient? Public health care spending in the US is at the same level as in many European countries, and the US spends twice as much if private health care spending is included. However, about 15 per cent of the US population have no health care insurance (Wilkerson, 2003; Green-Pedersen and Wilkerson, 2006). In other words, there are signiﬁcant problems attached to expenditure data as a measurement of the extent of retrenchment in relation to core welfare state programmes such as pensions, health care and unemployment beneﬁt. To a large degree, the use of social expenditure data is problematic because they are eﬀectively outcome data. All four types of problem mentioned above are to some extent caused by other factors than changes in welfare programmes aﬀecting social expenditure. Returning to the discussion above, the use of social expenditure as outcome measure is not a problem if the theoretical deﬁnition of retrenchment is based on outcome. However, most studies which use social expenditure data in reality have an output focus. They aim to measure changes in social policy programmes in order to assess the importance of government partisanship, for example. Other studies, such as Hacker (2002; 2004) adopt an explicit outcome focus, but the outcomes they focus on, such as inequality, are poorly captured by social expenditure data. The discussion above should not be read as an argument against the use of expenditure data, but as underlining that there are strong reasons to look for other data sources which might supplement social spending. Recent studies (Korpi and Palme, 2003; Allan and Scruggs, 2004) have used net replacement rates in selected welfare programmes to study welfare state retrenchment (see Kangas and Palme, Chapter 6, and Scruggs, Chapter 7, this volume). This

Theoretical conceptualization and the dependent variable ‘problem’

21

avoids some of the problems of using expenditure data, e.g. rising number of recipients, but raises other problems, which also partly stem from using an outcome measure to evaluate output related questions. Firstly, replacement rates are only one aspect of welfare programmes. Moreover, changes in replacement rates are inﬂuenced by other factors such as wage levels and taxation rules. In other words, the link back to government policy can be quite indirect. Governments may, for instance, improve beneﬁts and at the same time replacement rates might decline due to wage increases. Although relatively underdeveloped, an alternative to outcome measures such as expenditure data or replacement rates for the assessment of retrenchment are output measures. Kitschelt (2001) suggests an index measuring changes made in social security in relation to the level of beneﬁts, eligibility criteria, etc. Thus, retrenchment could be measured by ‘microdata’, that is data providing a quantitative measure of the degree of retrenchment implied by individual changes in social security schemes. Elsewhere I have applied such ‘output data’, measuring the degree of retrenchment following from a speciﬁc change in a welfare state programme by its likely budgetary eﬀect (the percentage of the total amount of cash spent on the programme) (Green-Pedersen, 2002; cf. also 2000). This measurement is calculated using statistical information about the scheme and material from the parliamentary reading of legislative proposals. Another example of an output measure has been developed by Lindbom (2005). Using the economic model of the Swedish Ministry of Finance, he calculated what the current expenditure on diﬀerent programme would had been had the rules which applied in 1991 not been changed, and then compared this with actual expenditure. The latter method is clearly more reliable, but of course requires access to an economic model. Compared with outcome measures the strength of output measures, such as the two examples presented above, is the much clearer connection with political decisions, which is, of course, particularly important if the underlying theoretical deﬁnition is output related, e.g. in Green-Pedersen (2002), who provides retrenchment measures for each programme change. Furthermore, it allows an assessment of long-term eﬀects thus avoiding time-lag problems associated with expenditure data, while being able to take all aspects of programmes into account. However, output measures have major drawbacks too. Even with access to statistical models, various assumptions about recipient numbers, etc. have to be made in order to forecast eﬀects arising from legislative changes. In some cases, such as the Swedish pension reform, changes in the programmes were deliberately made in ways which make their future eﬀects uncertain. Finally, it is also a very time consuming exercise requiring language skills, etc. in order to develop output measures.

22

The ‘dependent variable problem’ in comparative welfare state research

When considering operational deﬁnitions of welfare state restructuring, output perspectives focusing on institutional aspects might be justiﬁed in line with Esping-Andersen’s argument against spending, i.e. his claim that ‘it is diﬃcult to imagine anyone struggled for spending per se’ (1990: 21). With regard to the question of operational deﬁnitions, it is crucial to remember that Esping-Andersen did not replace expenditure data with qualitative assessments, but with indices measuring institutional traits of welfare state programmes. Thus the need for operational deﬁnitions and indicators also relates to studies focusing on welfare state restructuring. One way is to construct indices of change. Of course, this will always imply an element of arbitrary judgement. However, this should not lead to dispensing with empirical indices. Instead, it requires an explicit discussion of the criteria which guided their construction and the robustness of indices against changes in such criteria. Chapter 8 by Clasen and Clegg in this volume provides a ﬁne example of such an index approach, while Kvist (1999 and Chapter 9 in this volume), as well as Vis (forthcoming), also show how the fuzzy-set methodology can be used to measure the restructuring aspects of welfare state change.

CONCLUSIONS The previous decade has witnessed the emergence of an extensive literature dealing with welfare state reform, and to some extent the knowledge of these reforms is much greater today than it was ten years ago. However, the reform literature is much richer in theoretical hypotheses about the eﬀect of diﬀerent political and economic factors on welfare state reform than it is on empirical ﬁndings about the scope of reforms actually carried through. Notably, the question of which welfare states have been reformed more than others remains in many ways still unanswered. This chapter has argued that the lack of progress relates to the failure of adequately addressing issues connected with the dependent variable, i.e. questions such as ‘What is a reform?’ and ‘How can it be measured?’. The dependent variable ‘problem’ is thus not so much the fact that variables can be diﬃcult to measure and reliable data hard to obtain (which are both common in any type of empirical social science research); the ‘problem’ lies more in the lack of attention paid to the issues and the dominance of studies based on social expenditure data. This chapter has argued that the starting point for such discussions of the dependent variable should be theoretical in nature. Welfare state reform can mean many diﬀerent things. The suggestion of distinguishing welfare state retrenchment and welfare state restructuring also highlights the importance

Theoretical conceptualization and the dependent variable ‘problem’

23

of the diﬀerence between an output and an outcome perspective adopted in research of welfare state reform. In other words, one reason for the lack of progress and the continuing disagreement on the scope and relative extent of reform may simply be found in the varying deﬁnitions of reform applied. A country may have retrenched its welfare state signiﬁcantly without reconstructing it and vice versa. However, another aspect of the dependent variable ‘problem’ lies in the way the literature has typically approached issues relating to measurement of retrenchment, often distinguishing research which relies on expenditure data from studies engaged in ‘qualitative assessment’. As argued above, this is an unhelpful perspective. There are some problems related to the use of social expenditure, but the use of other indicators implies other problems. The use of social expenditure data becomes a serious problem if no other indicators are used allowing for a comparison of ﬁndings from diﬀerent indicators. Thus, an important challenge for research on welfare state reform and retrenchment is to develop empirical indicators, which – together with social expenditure data – can answer questions such as which welfare states were reformed the most.

NOTES 1. This chapter is a revised and updated version of Green-Pedersen (2004). Thanks to the participants in the Stirling seminar, May 2005 on the ‘Dependent variable problem’, especially Jochen Clasen and Nico A. Siegel, for useful comments on an earlier version of this chapter. 2. In the following, welfare state reforms will be used as a general term covering diﬀerent types of changes to welfare state programmes. We can distinguish between two types of change, namely welfare state retrenchment and welfare state restructuring, see below.

3. Too narrow and too wide at once: the ‘welfare state’ as a dependent variable in policy analysis Giuliano Bonoli INTRODUCTION The ‘welfare state’, the object of a substantial amount of policy research over the last three decades or so, is an ill deﬁned entity. Deﬁnitions found in the literature tend to be based either on vague notions such as ‘policies that aim to improve people’s welfare’ or as enumerations of policies that belong to the welfare state. None of these approaches is really satisfactory. In the former case, it is diﬃcult to think of a policy that does not aim to improve people’s welfare. In the latter, by relying on an unspeciﬁed listing of policies, we miss the criterion that tells us what belongs to the welfare state and what doesn’t. This confusion has arguably always represented a problem for social policy research, but in the current postindustrial social and economic context, an unclear understanding of what we mean by ‘the welfare state’ is a major obstacle to insightful analysis. Over the last 20 years or so, we have witnessed the development of new policies, such as child care or active labour market policies, which have little in common with the traditional protective and de-commodifying function of postwar welfare states. These new policies do not aim to protect individuals from market forces; instead they have the objective of improving their chances to succeed in the market. They do not promote de-commodiﬁcation; they improve the quality of life of highly commodiﬁed workers. Are these new policies part of the welfare state? In this chapter I argue that a conceptually coherent deﬁnition of a dependent variable for social policy research must take into account changes in the fundamental nature of social policy, in particular, those which have occurred as a result of the transition from predominantly industrial social and economic structures to postindustrial ones. On this basis, the ‘welfare state’ is found unsuitable for the analysis of social policies both in industrial societies 24

25

and in the postindustrial age. In the former case, the welfare state is too narrow a dependent variable, since countries have used a whole range of instruments to tame markets and improve the living conditions of industrial workers. In the latter, the welfare state is too broad a category, because it conﬂates the old social policies, inherited from the postwar years and designed to deal with industrial social risks, and the new social policies developed to deal with social problems stemming from postindustrialization. The argument is developed in two stages. First I examine the adequacy of the welfare state as a dependent variable of social policy analysis in the context of industrial societies. On the basis of comparative historical studies, I argue that ‘functional equivalents’ to what is commonly considered as part of the welfare state must be included in the dependent variable. In the second part of the chapter, in contrast, I show how using the welfare state as a dependent variable in the current context conﬂates policies with diﬀerent objectives, targeting diﬀerent groups and developed in response to diﬀerent social transformations. These should be analysed separately.

SOCIAL POLICY IN INDUSTRIAL SOCIETIES: REDUCING WAGE EARNERS’ EXPOSURE TO MARKET FORCES One of the clearest and most inﬂuential deﬁnitions of what a welfare state is, is the one developed by Asa Briggs. According to him, ‘A “welfare state” is a state in which organized power is deliberately used [. . . ] to modify the play of market forces.’ Unfortunately, presumably in order to clarify his thought, Asa Briggs continues by listing typical areas of intervention of welfare states ‘ﬁrst by guaranteeing individuals and families a minimum income irrespective of the market value of their work or their property; second, by narrowing the extent of insecurity by enabling individuals and families to meet certain “social contingencies” (for example sickness, old age and unemployment) . . .; and third, by ensuring that all citizens without distinction of class or status are oﬀered the best standards available in relation to a certain agreed range of social services’ (Briggs, 1961 [2000] p. 228). It is in fact the second part of his deﬁnition that proved most inﬂuential, being picked up in many social policy textbooks. But in the search for conceptual clarity, it is deﬁnitely the ﬁrst part of Briggs’ deﬁnition that helps us the most. The welfare state is understood as actions that make use of political power in order to modify the distribution of goods and services that result from market exchanges. It is a clear deﬁnition that, at least on an abstract level, helps us distinguish actions that belong to the welfare state from those that do not. Its main problem, of course, is that

26

The ‘dependent variable problem’ in comparative welfare state research

it deﬁnes the welfare state against a hypothetical state in which all goods and services are exchanged according to market principles. The fact that such a state has never existed in human history makes it diﬃcult to operationalize this deﬁnition. All human societies, including the early forms of capitalism, have framed market exchanges so as to modify their outcomes, though with diﬀerent instruments and to diﬀerent degrees (Polanyi, 1957). In the United Kingdom, the objective outlined in the ﬁrst part of Asa Briggs’ deﬁnition of the welfare state, the deliberate use of organized power to modify the play of market forces, has been pursued essentially through the instruments that he mentions in the second part of his deﬁnition: income support, social insurance and social services. The British welfare arrangement was based on the assumption that the market was to be allowed to operate as freely as possible, while the state would compensate the resulting distribution of resources, but only ex post. This view of the relationship between the state and the market is summed up by T.H Marshall’s deﬁnition of welfare-capitalism: The hyphen links two [. . .] diﬀerent and contrasting elements together to create a new entity whose character is a product of the combination, but not the fusion of the components, whose separate identities are preserved intact and are of equal and contributory status. (Marshall, 1981: 124, emphasis added)

The role of the state here is understood as a form of intervention that takes place only after resources have been allocated according to market principles. But this conceptualization of welfare capitalism does not travel very far. Britain is in fact rather exceptional in this respect. Other industrial countries have relied on a mix of instruments to tame markets, which include the regulation of the labour market and the use of trade policy as an instrument to protect wage earners against the vagaries of modern markets. Social Policy through Labour Market Regulation1 A number of recent studies have pointed to the existence of ‘functional equivalents’ to income replacement programmes and social services, insofar as the provision of economic security to wage earners is concerned. Often these functional equivalents have been found within the realm of labour law or industrial relations (Castles, 1985; Mares, 1996; Whiteside and Salais, 1998; Bonoli, 2003a). Castles, for example, challenges the predominant view of Australia being a typical ‘welfare laggard’ by arguing that for this country a focus on social programmes alone does not accurately reﬂect the extent to which its citizens have been protected against market risks. A developed system of wage

determination plays an important role in enhancing the degree of welfare enjoyed by its citizens. For most of the 20th century, wages have been set by the courts on the basis of social criteria, at a level deemed suﬃcient for a (male) wage earner supporting a family (Castles, 1985). Other authors have emphasized the role played by labour laws in protecting the incomes of wage earners against the risk of low pay and unemployment. In continental Europe (particularly in the South), minimum wages, collective bargaining systems, and employment protection laws provide wage earners with job security and protection against the risk of being paid poverty wages. These policy instruments are akin to income transfer programmes insofar as their function is concerned: even though they use a diﬀerent channel, they provide economic security to wage earners (Mares, 1996; Whiteside and Salais, 1998). As argued elsewhere (Bonoli, 2003a), cross-national variation in relation to these labour market based social policy instruments seems to follow a pattern of ‘families of nations’ (Castles, 1993). In general, the legal regulation of employment is stronger in Latin European countries (France, Spain, Portugal, and Italy). Collective bargaining, in contrast, is an important source of economic security for workers in Germanic and in Nordic countries. It is in fact only in the US and in the UK that these instruments did not develop to any signiﬁcant extent. My claim here is that capitalist societies have developed diﬀerent instruments for providing economic security to wage earners. The welfare state is only one of the channels that have been used to that eﬀect. In addition to building welfare states, and sometimes as an alternative to them, several market economies have developed sophisticated systems of labour market regulation that either through legislation, or through self-regulation by labour market actors, substantially increase the level of economic security experienced by wage earners. In this section, I focus on three sets of instruments: labour laws, collective bargaining, and redistributive income transfer programmes. Law based regulation of the labour market aiming at improving levels of economic security experienced by wage earners has taken a number of diﬀerent forms. Perhaps the most obvious example is employment protection legislation. Most industrial countries provide some legal protection against dismissal, generally in order to avoid arbitrary lay-oﬀs, but sometimes also by limiting the freedom of employers to dismiss workers during recessions. Employment protection laws, as a result, can protect wage earners against the risk of unemployment, by securing their place in the labour market. In some countries, governments have also traditionally intervened in the process of wage setting, for example through minimum wages set by law which constitute a ﬂoor below which employment

relationships are illegal. Wages can also be regulated by imposing collectively negotiated agreements upon employers and workers who are not among the original signatories to the agreement, a process known as extension. These instruments are used to a diﬀerent extent in diﬀerent countries (see Table 3.1, columns 1 to 4). Broadly speaking, the use of legislation to regulate labour markets is strongest in Latin Europe and weakest in English speaking countries. Between these two extremes, reliance on labour law as a social policy instrument is relatively weak in the Nordic countries, and somewhat stronger in continental Europe. This clustering of countries could in reality be even clearer than is suggested by Table 3.1. In fact, the information presented refers to formal instruments, which are not necessarily used to the same extent in diﬀerent countries. For example, even though extension laws of collective agreements are common both in continental and in Latin Europe, they are used much more sparingly in the former (especially in Germany and Switzerland) than in the latter. Collective bargaining is the second labour market based instrument for providing economic security to wage earners examined in this chapter. Typically, countries with all-encompassing collective agreements (sectoral or national) have been able to protect low wages to a much larger extent than countries which lack a tradition of collective bargaining (UK, US), in spite of economic trends that push in the direction of more earnings inequality (Rueda and Pontusson, 2000). In addition, collective agreements generally regulate a host of other aspects of employment contracts, such as working hours, holidays, fringe welfare beneﬁts, and so forth. Table 3.1 (columns 5 and 6) provides information on the importance of collective bargaining cross-nationally. The level at which collective bargaining takes place can be relevant to the eﬀectiveness of this instrument, as usually the bigger the unit the stronger the bargaining power of the unions, and hence the concessions in terms of wages and other aspects of economic security they can obtain. The eﬀectiveness of collective bargaining depends also on the coverage it can achieve. There are important variations, with the highest rates achieved in continental Europe and among Nordic countries. Latin European countries have fair degrees of coverage for collective agreements, but this is often the result of the use of extension laws (Ebbinghaus, 1998). In this respect, high rates of coverage for collective agreements in Latin Europe are not so much the result of selfregulation by labour market actors (as is the case in continental Europe) as a reﬂection of the tradition of state economic interventionism which is typical of these countries. Third, virtually all European countries have developed income transfer programmes that modify the primary allocation of resources produced by

labour markets. Relative to the previous two instruments, income transfer programmes can be seen as examples of compensatory social policy, or ex post social intervention, in so far as they are based on the acceptance of the market as the primary mechanism of resource allocation, combined with corrections aimed at redressing undesirable social outcomes. This is what is most usually considered under the label ‘welfare state’. Table 3.1 uses the proportion of GDP spent on tax ﬁnanced social programmes as an indicator that reﬂects the extent to which states intervene ex post to redress market outcomes. The indicator intentionally excludes spending on contributory social insurance programmes, which are more diﬃcult to classify according the threefold distinction adopted here. In general, social insurance is strictly related to employment, with beneﬁts being understood as a ‘deferred wage’. It also maintains employment based status diﬀerentials (Esping-Andersen, 1990; Palier, 2002). In this respect social insurance cannot be seen as a compensatory social policy, as it basically prolongs (labour) market outcomes instead of modifying them. Social insurance programmes essentially mimic the contractual and actuarial features of private insurance schemes. The overall distributional outcome of a pure social insurance scheme is thus often not very diﬀerent from what would result from a market based system. As a matter of fact, the social insurance based pension systems of France and Germany do not signiﬁcantly alter the income distribution produced by the labour market, as shown by the fact that in these countries levels of income inequality among working-age individuals and among pensioners are similar (Whiteford and Kennedy, 1995). There are two important exceptions where the role of social insurance as a provider of economic security is substantially diﬀerent from what would be achieved in a private system. The ﬁrst one is unemployment insurance, which cannot mimic the actuarial features of private insurance because of the non-random distribution of the risk of unemployment. Social insurance based systems of unemployment compensation provide coverage against the risk of unemployment to low-wage, high-risk individuals who would simply be unable to insure themselves on a private basis. As a result, they contribute to enhancing wage earners’ economic security relative to what they can achieve under pure market conditions. Second, many social insurance programmes do perform some vertical redistribution. This is the case for example of the British or the Swiss basic state pension, in which the link between contributions and beneﬁts is rather loose. In general, however, both unemployment insurance schemes and redistributive social insurance programmes are partly funded through general taxation, so that their redistributive component is captured by the indicator ‘tax ﬁnanced social expenditure’.

31

The extent to which states rely on redistributive income transfer programmes also varies signiﬁcantly across countries, being strongest in Scandinavia and weakest in Latin Europe. The English speaking countries occupy an intermediate position, but within the context of overall low levels of social expenditure, which suggests that tax ﬁnanced programmes play a relatively important role in these countries, in spite of the small proportion of GDP allocated to these programmes. On the basis of the data provided in Table 3.1, we can identify four diﬀerent ways of combining the three instruments dealt with in this chapter. First, the English speaking countries, where economic security is provided mostly through redistributive income transfer programmes, are weak in relation to the two other forms of social protection. Second, the Nordic countries show rather low levels of legal regulation of the labour market, but they compensate with strong collective bargaining and redistributive income transfer programmes. Third, continental European countries tend to have a fair degree of law based social protection, have strong collective bargaining institutions, but rather weak redistributive income transfer programmes. And fourth, Latin European countries have the highest degree of labour market regulation by law, but make little use of other forms of social protection. Table 3.1 supports the hypothesis that these diﬀerent forms of social protection are functional equivalents. Countries which developed strong employment protection have welfare states that perform little vertical redistribution and vice versa. Of course, the extent to which these policies are truly functional equivalents depends on the target group under consideration. As far as core workers are concerned, labour market based forms of social protection can provide levels of economic security that are comparable (if not superior) to those found in a fully ﬂedged welfare state. For marginal workers and for non-workers (female and young workers or unemployed people, the long-term unemployed), labour market based social protection is often of little use, hence in these cases the diﬀerent policy instruments discussed in this chapter are unlikely to be functional equivalents. Overall, although countries combine diﬀerent forms of social protection, they clearly have preferences for some forms over others. The clustering of countries which emerges from Table 3.1 is reminiscent of Francis G. Castles’ (Castles, 1993) categorization of Western countries into ‘families of nations’, and suggests that a number of historical developments might be relevant in determining the forms of social protection chosen by a society. In a related paper I have argued that these have to do essentially with the shape of state–society relationships and dominant ideological orientations at crucial historical moments in the development of contemporary societies (Bonoli, 2003b).

Protectionism and Social Policy In addition or as an alternative to standard social polices, industrial countries have also attempted to modify the play of market forces by protecting producers (and their employees) from competition. In most cases this has meant protection from foreign competitors through barriers to trade. This strategy was a key component of the postwar arrangement in countries like Australia and New Zealand. Economic protectionism and a restrictive immigration policy in Australia were the price to pay in order to keep wages high and in line with the expectations of wage earners (Castles, 1985). In New Zealand a protectionist trade policy was used in conjunction with wage restraint as a tool to guarantee full employment throughout the postwar years. Reliance on protectionism stemmed from the need to manage current account deﬁcits in the 1950s, after the ruling out of other options. But in the following years, successive governments kept quantitative restrictions on imports in place, because they permitted the preservation of full employment (Mabbet, 1995: 120–1). It is only in the 1980s, when protectionism begins to undermine the capacity of the New Zealand economy to grow, that this approach was gradually abandoned. A similar use of protectionism as an alternative to social policy is evident in the case of Switzerland. According to OECD expenditure data, this country has traditionally been one of the least developed welfare states, with social expenditure levels similar to those found in the US (except in recent years, when they have risen to Western European levels). But here too, markets have been tamed through other means. Protectionism, for instance, has been a key feature of agricultural policy, and often, through technical regulation, in many other economic sectors (e.g. food manufacturing, construction and related industries; infrastructure). In addition to protecting producers from imports, the Swiss postwar settlement was characterized also by the acceptance of non-competitive practices, such as cartels, among producers (Mach, 1999; Bonoli and Mach, 2000). These were as a result not really subjected to market forces. One consequence of this policy has been the persistence of relatively high levels of employment in the sheltered sectors of the economy in comparison to other countries, until the late 1980s. The other side of the coin has been of course the very high price levels that are common in the country, through which the ineﬃciency brought about by lack of competition has been ﬁnanced. Through channels that have little in common with what we usually consider the welfare state, New Zealand and Swiss citizens managed to develop mechanisms against the vagaries of markets that were able to deliver broadly similar social outcomes in terms of access to a decent income and

protection from social risk. These peculiar arrangements ran into trouble in the 1980s in New Zealand and in the early 1990s in Switzerland, when costs began to be seen as unacceptable not so much by consumers (who, as workers, where arguably also beneﬁting from the arrangement through full employment and high wages), but by the export oriented industry that relied on expensive domestic producers for subcontracting and infrastructure (communication, energy, etc.). Taming Markets with Diﬀerent Tools What is important to stress in the context of this chapter is the fact that for any attempt to map the extent to which industrial societies have managed to control and channel market forces, a focus on income transfer programmes and social services which is adopted in most of the comparative social policy literature, is unlikely to reﬂect the whole range of interventions that have been developed throughout the industrialized world. If the objective of research is to map diﬀerences in the extent to which wage earners are protected against market risks, then these alternative forms of social protection must be taken into account. Broadly similar objectives have been pursued in diﬀerent countries through completely diﬀerent means. This ﬁnding vindicates the Polanyian view that human societies and free markets are incompatible. Countries like Switzerland and New Zealand, which in welfare state league tables show up at the bottom, simply used other means to contain the socially disruptive character of free markets. This should be taken into account in international comparisons of welfare capitalism, and comparative studies of social policy in the industrial age should use an expanded dependent variable which does justice to the extent of crossnational variation highlighted in the ﬁrst part of this chapter.

WELFARE CAPITALISM IN THE POSTINDUSTRIAL AGE As suggested by the numerous references to the work of Karl Polanyi, historically the above discussion applies to industrial capitalism only. The welfare state and the other forms of protection outlined above can be seen as responses to the commodiﬁcation of labour resulting from the industrial revolution. While the aspiration for protection against market forces remains strong in postindustrial societies, over the last few decades we have witnessed the appearance of new demands on the welfare state, essentially in response to emerging new social risks (Bonoli, 2005; 2006). Is it a suitable research strategy to lump these new policies together with those that

34

The ‘dependent variable problem’ in comparative welfare state research

we have inherited from the industrial days? In the remainder of this chapter, I argue that this is not the case. New Social Risks in Western Welfare States The ﬁrst set of new demands comes from women. Because of the gender contract that was dominant throughout the 20th century, most women did not suﬀer exposure to market forces, but experienced a dependency on family ties such as marriage (Lewis, 1992). And women were largely ignored, both by the industrial welfare state and by the alternative forms of protection reviewed above. Income replacement programmes were geared towards preserving the income of the male breadwinner whereas the objective of employment and trade policy was male full employment. But things begin to change in the 1970s, when especially in Northern Europe, we see the emergence of increasingly strong demands from women for new policies that respond to their needs and aspirations. These take diﬀerent forms. In Sweden, for instance, they are based on claims for free child care while in Germany they emphasize more the recognition of the unpaid domestic work (Naumann, 2005). These new demands have had and are having an impact on the welfare state, as policies that respond to them have been and are being developed throughout Western Europe. These policies, however, have little in common with the market protecting, decommodifying eﬀorts of the old days. They are certainly not aiming at reducing people’s dependence on labour market participation. Quite the contrary, they are likely to facilitate employment, through ‘positive’ commodiﬁcation (Knijn and Ostner, 2002). The second set of new demands stem from deindustrialization and its consequences, both in terms of mass unemployment and in terms of a labour market where the service sector is predominant. Even though the total volume of employment has not decreased over the last four to ﬁve decades, the replacement of industrial jobs by service sector employment has left large numbers of former industrial workers jobless and unable to reintegrate into the labour market in the service sector. The key consequence of this development has been long-term unemployment, a social risk that was virtually unheard of during the trente glorieuses. Industrial longterm unemployment, however, may not be the most important social consequence of de-industrialization, especially since it is a temporary phenomenon, related to the transition from predominantly industrial to predominantly service based economies. As cohorts of dismissed industrial workers reach retirement age, this type of unemployment will slowly fade away. The decline of manufacturing and the expansion of service employment, however, have altered labour markets in a more fundamental way, especially

at their lower end, consisting of low-skill, low-value-added jobs. Low-skill individuals have obviously always existed. However, during the postwar years, low-skill workers were predominantly employed in manufacturing. They were able to beneﬁt from productivity increases due to technological advances, so that their wages rose in line with those of the rest of the population. The strong mobilizing capacity of the trade unions among industrial workers further sustained their wages which came to constitute the guarantee of a poverty-free existence. Today, low-skill individuals are mostly employed in the low-value-added service sector or unemployed. Low-value-added services such as retail sale, cleaning, catering, and so forth are known for providing very little scope for productivity increases (Pierson, 1998). In countries where wage determination is essentially based on market mechanisms (US, UK, Switzerland) this means that low-skill individuals are seriously exposed to the risk of being paid a poverty wage. The situation is diﬀerent in countries where wage determination, especially at the lower end of the distribution, is controlled by governments (through generous minimum wage legislation) or by the social partners (through allencompassing collective agreements). Under these circumstances, the wages of low-skill workers are protected, but job creation in these sectors is limited, so that many low-skill individuals are in fact unemployed (Iversen and Wren, 1998). Overall, the fact of possessing low or obsolete skills today entails a major risk of welfare loss, considerably higher than in the postwar years. Like demands for new policies for women, the plight of low-skill individuals has resulted in new demands put on welfare states. These are to a large extent shaped by the existing labour market – welfare state arrangements. In highly regulated labour markets that produce high levels of lowskill unemployment, these demands translate into policies designed to help the jobless enter the labour market, or active labour market policies. In unregulated labour markets, the eﬀort of policy is directed towards improving the living conditions of the working poor, most notably through tax credit programmes (OECD, 2003). New Policies for New Risks The new social risks that have emerged as consequences of the transition to postindustrial societies have resulted in the development of related social policies. Of course, like the construction of postwar industrial welfare states, the process is uneven and has reached diﬀerent levels in diﬀerent countries. But the key point here, from the perspective taken by this chapter, is that the policies adopted in order to respond to new social risks are qualitatively diﬀerent from those that constituted the cornerstone

36

The ‘dependent variable problem’ in comparative welfare state research

of postwar welfare states. In the old days, social policy was above all about reducing workers’ dependence on the vagaries of markets (decommodiﬁcation); today most new policies are about improving the living conditions of those workers and citizens who as a result of postindustrialization are facing new diﬃculties and dilemmas. These two sets of policies not only have a diﬀerent objective. They also cater for somewhat diﬀerent social groups. The key target of the postwar welfare state was the male breadwinner and the protection of his income. Still today, the main beneﬁciaries of the key programmes that constituted the backbone of the postwar welfare state: old-age pensions, invalidity and sickness beneﬁts, tend to be found among men and older age groups, nationals and long established immigrants. In contrast, the key beneﬁciaries of the new social policies tend to be found above all among women, young people and new immigrants. These two reasons, a diﬀerent objective and a diﬀerent target population, should lead us to consider these two sets of policies as ‘diﬀerent animals’, which should be analysed separately. What is particularly intriguing is the fact that such an analysis reveals some important diﬀerences in terms of degree of development in the two sets of policies. Policies catering for the traditional social risks have reached the highest level of development and generosity in continental and Southern Europe. This view, which obviously contrasts with Esping-Andersen’s ranking of welfare states in terms of de-commodiﬁcation (Esping-Andersen, 1990), is based on the inclusion in the analysis of two additional elements. The ﬁrst element is law based regulation of the labour market with social policy objectives, discussed at length in the ﬁrst part of this chapter. Continental and in particular Southern European countries which score low on de-commodiﬁcation used a diﬀerent channel to provide economic security to wage workers, which is not captured in Esping-Andersen’s analysis. The second additional element is the age of retirement. Esping-Andersen focuses on three features of pension systems: the replacement rate, the degree to which entitlement depends on labour market participation, and universality. While these are important aspects in so far as the de-commodiﬁcation of wage earners is concerned, so is the likely duration of their retirement. And in this respect, continental and Southern European countries provide considerably more generous provision than the social-democratic welfare states of Northern Europe. As shown in Table 3.2, in the early 1980s, the average retirement age was three years lower in continental and Southern European countries than in the Nordic countries. This view is conﬁrmed by an analysis based on social expenditure on each of the two sets of policies. We know from previous research that social expenditure as a proportion of GDP is a very crude and sometimes

inadequate indicator to reﬂect the eﬀort made by a country in a given policy ﬁeld (see also Chapter 4 by Siegel, Chapter 5 by De Deken and Kittel and Chapter 7 by Scruggs, this volume). However, it is a useful and convenient way to provide a ﬁrst approximation. Figure 3.1 presents aggregate expenditure data on both old and new social risk (NSR) policies. The picture emerging from Figure 3.1 conﬁrms what has been argued above. The most generous (or costly) postwar welfare states are found in continental and Southern Europe (especially Italy, Austria, and for the time being in Switzerland), while the most comprehensive systems of new social risk policies are located in the Nordic countries (but also in France). This ﬁnding raises a number of issues, the most important of which is probably the question of what the factors are which explain the development of postwar welfare states and NSR policies respectively. The fact that these did not develop in parallel suggests that the independent variables of each set of policies are diﬀerent, or exert their eﬀect in a diﬀerent way. Elsewhere (Bonoli, 2006) I argue that the timing of the emergence of new social risks in a country in relation to the process of population ageing is

Spending on NSR policies Note: Old social risk policies includes old age cash beneﬁts, survivors and incapacity cash beneﬁts and unemployment cash beneﬁts; New social risk policies include spending for families (cash and services) and active labour market policies, old age services, invalidity services and social assistance (cash and services).

Figure 3.1 Spending on old (OSR) and on new (NSR) social risk policies in OECD countries as a percentage of GDP, ﬁve-year averages, 1997–2001 crucial in determining the development of the corresponding social policies. If NSR develop relatively early, when the ﬁnancial requirements of pensions and health care systems are still modest, then we are more likely to see the development of a comprehensive system of NSR policies (Nordic countries). In contrast, if NSR emerge when pension and health care systems have to face additional expenditure due to population ageing, then the development of such a new welfare state will be considerably more diﬃcult. But the relevant point in relation to the question addressed by this chapter is that there is little reason to conﬂate old and new sets of social risk policies into a construct called ‘the welfare state’. These two sets have diﬀerent objectives, use diﬀerent instruments, target diﬀerent groups of people and have developed in response to diﬀerent social transformations. It is diﬃcult to see why they should be considered together.

The ‘welfare state’ as dependent variable in policy analysis

CONCLUSION: THE APPROPRIATE DEPENDENT VARIABLE This chapter has argued that more attention should be paid to the choice of an appropriate dependent variable in social policy analyses. In comparative studies the dependent variable has often been chosen and deﬁned rather uncritically, on the basis of institutional traditions, in particular because of the UK’s historical lead in social policy research on the British institutional tradition, rather than on the basis of sound intellectual arguments. The discussion above suggests that it is possible to identify two sets of criteria that should be of help in choosing the appropriate dependent variable. First, the best dependent variable depends on the period under consideration. Studies of industrial social policies should deﬁne their dependent variable broadly, so as to include functional equivalents developed in diﬀerent countries. Otherwise, they run the risk of misrepresenting the extent to which wage earners are protected from the vagaries of markets. In contrast, studies of postindustrial social policy should not conﬂate those policies that were inherited from the postwar years with those developed in the current postindustrial socioeconomic context. Second, dependent variables should be adapted to the research question that is being investigated. If the objective is to assess the extent to which citizens are protected from social risks, whether historically or today, then the broader understanding seems more appropriate. If the objective of research is to study the determinants of policy making, in particular within the political arena, then a narrower dependent variable may be more suitable. In more general terms, we can conclude by arguing that dependent variables in comparative policy research should be selected accurately, and that they should be coherent and comprehensive. They must be coherent, because a high degree of internal unity is needed, if one wants to use them in comparative analysis. But they should also be comprehensive; otherwise we risk missing relevant instruments that just happen to be categorized under diﬀerent policy areas in diﬀerent countries.

Measuring and analysing ‘welfare eﬀorts’: social expenditure revisited

4. When (only) money matters: the pros and cons of expenditure analysis Nico A. Siegel Expenditures are epiphenomenal to the theoretical substance of welfare states. (Esping-Andersen, 1990) Money is not all there is to policy, but there is precious little policy without it. (Klingemann, Hoﬀerbert and Budge, 1994) The whole notion of a ‘race to the bottom’ is premised on dog-eat-dog cuts in expenditure and taxation. (Castles, 2004)

INTRODUCTION1 This chapter focuses on a particular dependent variable problem in comparative welfare state research. It will assess the strengths and limits of comparative inquiries analysing welfare states mainly or even exclusively on the basis of social expenditure data. Although the major aim of this chapter is to discuss the speciﬁc problems of expenditure based analyses, it will also address more general methodological issues which are related to the dependent variable problem in macroquantitative comparative welfare state research. Over the last decade the comparative analysis of welfare reform has become a booming research ﬁeld. More than a decade ago, Paul Pierson’s seminal work on the political logic of and limits to welfare state retrenchment sparked oﬀ a lively and ongoing debate about the so-called ‘new politics of the welfare state’ (Pierson, 1994). This discussion about the old and new politics of the welfare state is far from being settled (Pierson, 2001; Castles, 2004). Scholars from various disciplines and from distinct analytical angles have investigated welfare state change in advanced societies and presented strikingly divergent results concerning both the scope of change 43

Measuring and analysing ‘welfare eﬀorts’

and the factors determining its direction. The core argument of this chapter (as generally of the volume to which it contributes) is that beyond normative and theoretical-analytical reasons, basic methodological problems – and in particular a virulent dependent variable problem – have contributed to the strikingly divergent conclusions characterizing the current state of the art in the analysis of welfare state change in advanced societies. This chapter provides both an overview of the strengths and weaknesses of expenditure analysis in general, and a more detailed account of research problems that result from the speciﬁc nature of expenditure data when welfare state change is analysed. In what follows, I will ﬁrst outline why and how the dependent variable problem is related to expenditure based welfare state comparisons before providing a discussion of the potential strengths and problems of using social expenditure data for a comparative assessment of welfare state change. The ﬁnal section concludes.

THE DEPENDENT VARIABLE AND EXPENDITURE ANALYSIS One set of questions that is of central importance in comparative research focusing on welfare reform in advanced societies may be summarized as follows: what happened to advanced welfare states during the last two and a half decades of the 20th century? Did welfare states undergo a process of retrenchment or of continued expansion? As welfare states represent entities, their change might not be measured adequately if one-dimensional (quantitative) scales are used, hence: do we have to conceptualize welfare state change in more complex multidimensional ways than terms such as ‘retrenchment’ or ‘expansion’ suggest? The relevant literature provides several answers to these questions. Most country studies based on qualitative in-depth analyses of social policy programmes and comparative inquiries into legislative changes have presented evidence showing that the generosity of social rights was adjusted downwards in OECD countries during the 1980s and 1990s. According to these studies, the majority of OECD countries implemented some sort of cost containment measures during the ‘silver age of welfare capitalism’ (TaylorGooby, 2004). While most authors agree that in most countries and contexts cutbacks were rarely of a radical nature, they also agree that cutbacks have contributed to reduced beneﬁt generosity in core welfare state programmes such as pensions and health care (Clayton and Pontusson, 1998; Siegel, 2002). In contrast to these ﬁndings suggesting considerable change, macroquantitative studies that have mainly analysed trends in (total gross) social

Figure 4.1 Public social expenditure in 21 OECD countries, 1980, 1993 and 2001 expenditure in the post-1980 era have found little or almost no evidence for successful cost containment policies. Whereas the remarkable growth of social expenditure (as a percentage of GDP) was a common post-World War II feature across the OECD world up to the 1970s, spending increases slowed down from 1983/84 onwards and particularly during the second half of the 1980s (see Figure 4.1 and Table 4.2). For the 1990s, one may diﬀerentiate two major sub-periods. During the ﬁrst few years most countries experienced a sharp increase in total public social expenditure. Even without an in-depth investigation of the legislative changes which may have contributed to this rise in social expenditure, it is possible to demonstrate by regression analysis that in most countries the economic recession at the end of the 1980s and early 1990s contributed decisively to the expansion of welfare eﬀorts in that period.2 However, the economic recession of the early 1990s was soon superseded by an economic upswing. Thus, in the majority of OECD countries welfare eﬀorts started to decrease again after they had peaked in 1993 or 1994. However, a comparison of social expenditure levels in 1980 (again measured as a percentage of GDP) with those in 2001 does not suggest a massive rollback of the welfare state. Some countries with

46

Measuring and analysing ‘welfare eﬀorts’

initially relatively low levels of social expenditure (for example Australia, Portugal and particularly remarkably, Switzerland), went through a notable catch-up process. In contrast, for some (but not all) of the ‘top spenders’ in the OECD league, ‘catch-down’ was characteristic after spending had peaked in 1993 (e.g. in Denmark and Sweden) or 1994 (the Netherlands). A comparison of detailed country studies and comparative social rights based analyses (see also Chapter 7 by Scruggs, and Chapter 6 by Kangas and Palme in this volume) with the results of most quantitative inquiries based on aggregate spending trends reveals divergent ﬁndings. This highlights why and how the choice of the key indicator for the dependent variable aﬀects the results of descriptive accounts of welfare state change. It also exempliﬁes a speciﬁc dependent variable problem of comparative welfare state research that has been identiﬁed by several authors: the lack of attention paid to a discussion about appropriate (macro and micro) measures of welfare state change and about the operationalization of concepts such as ‘retrenchment’ or ‘restructuring’ (Alber, 1996; Clayton and Pontusson, 1998; Clasen et al., 2001; Siegel, 2002; Green-Pedersen, 2004). In this respect, comparative welfare state research seems to be a showcase for a problem which Francis G. Castles has identiﬁed as a common one in social science research in general, i.e. that ‘social sciences systematically under-invest in measurement and hypothesis testing’ (Castles, 2004: 10). The robustness of conclusions in macrocomparative welfare state research suﬀers from a general lack of more sophisticated measurement tools.3 One might disagree with the second part of Castles’ diagnosis however, which states that social sciences also tend to under-invest in hypothesis testing. One of the most striking trends over the last two or three decades suggests exactly the opposite: abundant studies that have taken hypothesis testing and retesting very seriously – and according to some experts, at times perhaps too seriously if one takes account of the obvious substantial methodological problems these exercises regularly face, but which are generally not discussed in great detail (Kittel, 2004; also De Deken and Kittel, Chapter 5, this volume). Due to technological innovations such as the development of highly eﬃcient statistical software and new developments in regression analyses, a fast growing body of studies has tested and retested a rather small set of standard hypotheses on the basis of more or less the same case selection using expenditure data. Yet this expansion of the replication business in comparative welfare state research has not triggered impressive progress in terms of reﬁning existing theories or developing new ones. Instead, it has failed to produce robust empirical ﬁndings and delivered ambiguous conclusions which often seem to be built on rather thin empirical evidence.

The pros and cons of expenditure analysis

47

Compared to the growing number of quantitative studies in comparative welfare state research that keep the ‘replication business’ of quantitative hypothesis re-testing booming and suggest far reaching generalizations about complex processes of change, only a small number of studies have explicitly tried to systematically address basic questions of measurement and concept speciﬁcation – or tried to build bridges between theory and methodology research (however, see Green-Pedersen in Chapter 2 and Scruggs in Chapter 7 of this volume). As a consequence of the under-investment into the ‘empirical infrastructure’ of macroscopic welfare state research, fascinating concepts such as retrenchment, reform, recalibration, adjustment or restructuring have been introduced but not been followed by more rigid and thus testable operational deﬁnitions. The lack of attention to measurement issues causes serious problems for descriptive inferences in macroqualitative and macroquantitative studies. Things can only be more delicate at the level of analytical inferences. A fuzzy conceptualization of a descriptive dimension of welfare state change hardly provides a fruitful ground for robust analytical inferences (Alber, 1996). This leads us to a second set of key questions which is directly related to the dependent variable problem in the use of expenditure data in comparative welfare state research. It concerns the analytical dimension of investigating welfare state change. A fast growing body of literature has dealt with the social, economic and political factors that shape welfare state change in Western democracies. Some of the classical questions about the relevance of impact of national polities and politics have repeatedly been asked: do parties and power resources of collective social actors still matter for the politics of welfare state reform (Korpi and Palme, 2003)? Do we observe the ‘new politics’ of welfare state recalibration, shaped by path dependent trajectories of incremental adjustment and blame avoidance strategies of politicians whose strategic actions are dominated by (re-)election rationales (Pierson, 1994; 2001)? Given the enormous dissent concerning the basic problems of describing welfare state change, the dissent on the crucial factors shaping welfare state reforms is hardly surprising (Kitschelt, 2001: 299). Hence, the current literature on welfare state change is characterized by at times stunning overlaps and numerous contradictions. One striking example may be used to illustrate this point. Based on rather distinct research design both quantitative and qualitative studies have reported strong evidence for Pierson’s claim that retrenchment is not the ‘the mirror image of expansion’ (Pierson, 1994: 1) and for ‘the new politics of the welfare state’ (Ross, 1997 and 2000b; Huber and Stephens, 2001; Pierson, 2001). However, several other studies have

48

Measuring and analysing ‘welfare eﬀorts’

contested the new-politics paradigm and suggested that the ‘old politics of the welfare state’ is indispensable for understanding the political logic of contemporary welfare state reform (Clayton and Pontusson, 1998; Korpi and Palme, 2003). Again, other scholars claim to have found robust evidence for the seemingly paradoxical conclusion according to which the partisan composition of governments, a major ‘old politics’ factor, still shapes welfare state outcomes in an era of permanent cost containment – but in the opposite direction if compared with the ‘golden age’ of welfare state expansion. According to this view, left parties are in a better position to mobilize support for unpopular welfare state reform (such as beneﬁt cutbacks) as they are usually perceived as the most ‘natural’ pro-welfare state party. Consequently, at least in most national party system contexts, left parties may convincingly argue that any alternative political party to their right would implement even more severe cutbacks (Armingeon et al., 2001). According to this ‘Nixon-goes-to-China logic’ social-democratic governments should be in a better position to implement cutbacks than any parties to their right. However, based on a sophisticated pooled time series analysis of social expenditure trends in the post-1980s, Kittel and Obinger (2003) have challenged this ‘reversed partisan theory’. In contrast to previous social expenditure developments, their ﬁndings suggest that the 1990s did not witness a signiﬁcant partisan impact on welfare state spending. Finally, some authors have even dismissed the notion of a clear demarcation line between ‘old’ and ‘new’ politics of welfare state change. According to this notion, the two standard paradigms may not be perceived as strictly disjunctive ones. Rather, they may be viewed as at least partly overlapping analytical approaches which do not completely rule each other out. Due to the complex interplay of several factors shaping welfare state outcomes, the internal complexity of processes of welfare state change, and variable time lags between causes and eﬀects, it is very diﬃcult, at times perhaps indeed impossible, to diﬀerentiate between new and old politics factors in any real categorical sense (Siegel, 2002).4 In sum, what this chapter addresses might be labelled as the problem of ‘artless sophistication’ in macroquantitative comparative welfare state research. Artless sophistication is the consequence of innovations in ever more sophisticated techniques of data analysis which have been introduced into comparative social sciences without a systematic or critical assessment of their potential and their limits when it comes to analytical inferences. As a result, basic but substantial problems of macroquantitative (welfare state) research are often ‘assumed away’ for purely pragmatic reasons.5 As problems of data quality and consistency and, more substantially, of causal

inference are not discussed explicitly, but implicitly built into model speciﬁcations of regression analyses, research tends to produce rather unrobust ﬁndings. In what follows, this chapter provides a summary of major advantages and disadvantages of using expenditure data for exploring the dynamics of welfare state change. It will address the following questions: what are the major strengths of an expenditure sensitive approach to welfare state analysis? Why is expenditure analysis even more important in the era of ‘permanent austerity’ (Pierson, 2001) than during the golden age of the welfare state? What are the major pitfalls of expenditure based analysis in (a) describing and (b) analysing welfare state change? Why does the analysis of welfare state change over time raise more sensitive methodological issues than a purely cross-sectional perspective?

WHY AND WHEN MONEY REALLY MATTERS: EXPENDITURE ANALYSIS IN AN ERA OF PERMANENT AUSTERITY It may seem paradoxical but for a more extensive discussion of the advantages of expenditure analysis in comparative welfare state research it is worth revisiting one of the most frequently cited criticisms. It was Gøsta Esping-Andersen who argued that ‘[E]expenditures are epiphenomenal to the theoretical substance of welfare state’ (Esping-Andersen, 1990: 19) and that ‘[I]t is diﬃcult to imagine that anyone struggles for spending per se’ (Esping-Andersen, 1990: 21). There are indeed good reasons to subscribe to Esping-Andersen’s critique of expenditure based welfare state studies which apply readily available sets expenditure data sets for ‘testing’ theories of the welfare state. Two major caveats against a sweeping critique of expenditure based welfare state analysis deserve to be mentioned however. First, as I will argue below, both the history of the welfare state and the development of welfare state research provide us with numerous and important examples demonstrating that expenditure based approaches can oﬀer most valuable insights into welfare state change.6 The second point is related to the ‘new’ political economy of the welfare state which emerged in the aftermath of the ﬁrst oil price shock and manifested itself in the 1980s and 1990s. It is particularly characterized by the increasing salience of cost containment budgetary eﬀorts and is framed more generally by a political discourse that puts more emphasis on the costs of social provision than on the social and political achievements of welfare states.

Expenditure Analysis and its Pundits: Myths and Practice in Comparative Research It is worth putting Esping-Andersen’s frequently cited critique of expenditure analysis into the context of his own work. At several points in Chapter 1 of The Three Worlds of Welfare Capitalism, Esping-Andersen bluntly dismisses the value of comparative studies which carry out ‘theory tests’ by picking up easily available expenditure ﬁgures as ‘data fast food’ for the production of statistical outputs. He disapproves of the practice of using expenditure ﬁgures as the main dependent variable without critically discussing what expenditure actually indicates. His interest in structural and qualitative aspects of welfare statism reﬂects a much more ambitious approach to macrosociological research. However, a closer inspection of the empirical foundations on which Esping-Andersen’s regime typology is built shows that he himself was not reluctant to utilize spending data. The most striking example is the use of data for four out of seven indicators, of the public and private social expenditure for the construction of the stratiﬁcation index presented in Chapter 3 of The Three Worlds of Welfare Capitalism (Esping-Andersen, 1990: 69–78). Choosing a quite pragmatic approach to expenditure data EspingAndersen thus hardly qualiﬁes as a principal witness for a fundamental critique of any kind of expenditure based welfare state analysis. The main target of his criticisms was the apparently context-blind (mis)use of expenditure data for hypothesis testing which (implicitly) assumes that expenditure ﬁgures may be used as proxies for welfare state generosity. Thus the valuable criticism made by Esping-Andersen and others does not mean that sensitive expenditure approaches cannot provide instructive insights into welfare state proﬁles and developments. A disaggregated analysis of the structure of social expenditure, for example, can oﬀer important insights into the inherent spending asymmetry between diﬀerent branches of the welfare state. A closer inspection of the composition of the overall social budget can provide valuable estimates of the political salience of diﬀerent welfare state programmes. Although old-age cash beneﬁts generally consume the largest share of total social expenditure in national accounts, the proﬁles of OECD countries diﬀer signiﬁcantly in their structure of public expenditure (Siegel and Jochem, 2004). These ﬁndings can be immensely important for researchers (as well as politicians) involved in the kind of ‘cost containment’ debates or controversies which discuss the ﬁnancial sustainability of existing welfare state arrangements. There are other important substantial and pragmatic arguments against a general critique of expenditure analysis. Studies which have mainly or exclusively applied expenditure data have been pivotal to comparative

51

welfare state research since the late 1950s (e.g. Wilensky and Lebeaux, 1958). From the second half of the 1970s onwards and particularly in the 1980s some of the most inﬂuential studies in comparative social policy have used expenditure data as one of their prime measure of welfare state size and eﬀort (Castles, 1982b; Schmidt, 1982). Because social expenditure has become the largest component of total government outlays in all OECD democracies it is also the main predictor for the size of the tax state. Thus, the analysis of social expenditure trends is of the utmost importance for a broad range of questions concerning the history and the future of public policies in democratic countries (Castles, 1998; Schmidt, 1998; Siegel and Jochem, 2004). As long as spending ﬁgures are not misread as proxies for welfare state generosity (see below) a cautious analysis of social expenditure can certainly be an important and in some cases indispensable instrument of comparing welfare states and their change over time. However, there are important problems involved in using spending data for comparative research and about the way social expenditure is used in the current literature on welfare reform. One major pitfall is the use of increasing (or decreasing) levels of social expenditure as indicators for more generous (or restrictive) welfare provision. As will be discussed in more detail below, social expenditure should not be used as a proxy for the generosity of social rights (see also the Chapter 7 by Scruggs and Chapter 6 by Kangas and Palme in this volume). The generosity of social rights is directly aﬀected by political decisions, and is a major predictor of social expenditure. However, as social need and economic output also aﬀect levels and changes of social expenditure it is hazardous to use changes in social expenditure to infer (proportional) changes in the generosity of beneﬁts and/or services. There are ways to adjust social expenditure in order to make it more sensitive to questions of welfare state generosity. Several authors (Castles, 1982b; Clayton and Pontusson, 1998; Huber and Stephens, 2001) have analysed social expenditure in accordance with levels of social need, thereby calculating welfare-to-need ratios or ‘standardized welfare eﬀorts’ (Siegel, 2002). Again, it is worth bearing in mind that an ideal indicator might exist in research theory but certainly not in research practice. Thus, estimates of social need such as the level of unemployment or the size of the pensioner-age population should only be interpreted as rough proxies of more complex constellations of need. In other words, the assessment of social need deserves to be explored in much greater detail in the context of more thorough analyses of programme focused studies. But indicators such as the percentage of the population 65, of the unemployed, or the share of ‘income poor’ households may be used as reasonable need estimates for

52

Measuring and analysing ‘welfare eﬀorts’

cross-national comparisons. As comparative studies using needs adjusted expenditure trends have shown, ‘welfare-to-need ratios’ often deviate remarkably from non-adjusted gross social expenditure ﬁgures (Clayton and Pontusson, 1998; Siegel, 2002; Castles, 2004). The asymmetry between gross and needs adjusted social expenditure is particularly striking during and shortly after economic crises, e.g. in the aftermath of the ﬁrst oil price shock in the 1970s, in the early 1980s and during the recession of the early 1990s. While needs adjusted social spending started to decline in several OECD countries, accounts of gross (unadjusted) social spending suggested continuous expansive growth dynamics as a consequence of increasing social need in the context of low or even negative GDP growth. Breaking down total public social expenditure into programme speciﬁc trends, thereby climbing down the ladder of aggregation, is another useful tool for comparative welfare state researchers. Disaggregation helps to dismiss generalized judgements about welfare state developments which ignore at times highly variable trends within individual social policy programmes. One example is the huge diﬀerence between the level, and growth, of expenditure for old-age pensions on the one hand and for the support for the unemployed on the other. Despite popular beliefs, government spending on unemployment beneﬁts only marginally contributed to the growth of total social expenditure between 1980 and 2001. For the 20 advanced democracies, the OECD SOCX database contains ﬁgures for both the years 1980 and 2001 showing that the mean value for spending on unemployment beneﬁts was 0.97 per cent of GDP at the beginning of the period and 1.05 per cent of GDP in 2001. If one bears in mind that the average unemployment rate was more than one percentage point higher in 2001 than in 1980 (6.2 per cent vs 4.9 per cent, based on OECD ﬁgures for commonly used national deﬁnitions) and taking the stronger expenditure growth for health care and old-age pensions in most countries into account, these ﬁgures reveal a rather marginal growth dynamic and reduced welfare-to-need eﬀorts. Expenditure Analysis in the New Political Economy of the Welfare State Concerns about the use of expenditure data as ‘cost indicators’ are particularly salient when it comes to political debates about the cost of welfare in the ‘era of permanent austerity’ (Pierson, 2001). As cost containment policies have made it up to the top of government agendas in most OECD countries, and since the future of national tax states has become a major political battleﬁeld, one may just turn around some of the older assumptions about the (ir)relevance of expenditure ﬁgures. Only few governments in Western and Northern Europe have shown a clearly identiﬁable ideological commitment to rolling back the welfare

state, such as in the US and the UK of the 1980s. Nevertheless, as part of a more general shift towards cost containment and saving policies, governments in most OECD countries have implemented at least some entitlement cuts. Cutbacks and saving measures with ‘a bad conscience’ have been the rule rather than the exception in the majority of European welfare states where social-democratic and Christian democratic parties (in various coalition constellations) have often negotiated about cost containments measures within coalition governments. Processes of top-down budget policies which consist of spending caps and similar ﬁscal policy tools have become increasingly important. Compared to the golden age of Keynesian welfare state expansion, ‘social policy in hard times’ (Huber and Stephens, 2001) often involves redistributive zero-sum policies. Whereas in the 1960s and early 1970s increasing levels of social expenditure were used by centrist and left governments to highlight social achievements, expenditure ﬁgures are nowadays often presented as ‘cost indicators’. Both notions, the one focusing on ‘achievements’ only and the other emphasising exclusively the ‘cost’ of welfare, suﬀer from an ill balanced and somewhat simplistic core assumption – namely that (actual) expenditure equals real costs, which makes neither economic nor political sense. Just as it is misleading to confuse social expenditure levels with measures of social policy generosity, it is equally misleading to use expenditure accounts as measures for the societal cost of the welfare state: an all-encompassing deﬁnition of social or economic costs cannot be reduced to the level of outlays within a speciﬁed time period as it is reﬂected, for example, in annual budget ﬁgures. The search for an adequate measure that could be used to estimate the real (net) cost of welfare state policies is a knotty problem. One would have to calculate the net eﬀects of complex social, political and economic outcomes which are directly and indirectly aﬀected by welfare state policies. One also needs to specify the time horizon for a proper cost estimate, as many welfare state consequences only materialize over long periods of time or with a signiﬁcant time lag. As social expenditure should neither be confused with welfare state generosity nor with the complex costs of the welfare state, a rather neutral use of and label for social expenditure (as a percentage of GDP) seems to be most sensible for empirical-analytical welfare state research. ‘Welfare eﬀorts’, a term introduced by Wilensky and Lebeaux (1958: 156) almost half a century ago, oﬀers a reasonable label without emphatic or pejorative connotations. However, in contrast to Wilensky’s simplistic assumption according to which welfare eﬀorts reﬂect ‘the budget decisions of political elites’ (Wilensky, 1975: 17, footnote 1), they actually depend on a set of intervening and interdependent mechanisms, comprising factors of social

54

Measuring and analysing ‘welfare eﬀorts’

need, economic context (impacting on the denominator, GDP) and politically deﬁned generosity of social rights. As soon as one or more of these three dimensions change, one may notify a change in (total) welfare eﬀorts. The crux about welfare eﬀorts is that they (a) present expenditure sums based on data collected for individual social programmes and (b) represent a ratio which is determined by a numerate (social expenditure) and a denominator (usually Gross Domestic or Gross National Product). Hence welfare eﬀorts can be used as a reasonable estimate of the share of national economic output which is channelled through the diﬀerent pillars of a country’s social security system. Welfare state eﬀorts therefore reﬂect the elasticity of public budgets for social purposes but they certainly reﬂect more than the (direct) consequences of political decision making processes.

MAPPING THE LIMITS OF EXPENDITURE ANALYSIS Advanced welfare states of the majority of OECD countries comprise complex sets of diversiﬁed institutions and policies, of stratifying regulatory systems that shape societal outcomes in various ways. In most countries, welfare state policies do not only comprise quantiﬁable features of (direct) state intervention but also private and occupational systems. Not all policies which might be regarded as quantiﬁable are manifest in spending accounts. ‘Qualitative’ social policies, such as social regulations in health and safety or equal opportunity legislation have become increasingly important, particularly in the ‘spending poor’ context of EU social policy making (Majone, 1994). Until the 1990s, policies aﬀecting the regulation of product and labour markets had often been neglected in comparative welfare state research (but see Samek Lodovici, 2000). Yet regulatory policies represent an essential dimension of market restricting and correcting state intervention (Esping-Andersen and Regini, 2000). In terms of both welfare state size and its internal structure, important features of advanced welfare states are not reﬂected in public spending accounts. Hence whilst we have argued in the previous section that in many research contexts an expenditure sensitive approach to welfare state analysis is valuable, we also put strong emphasis on the notion that in many (or even most) research contexts approaches that rely exclusively on expenditure indicators provide a too narrow perspective on the welfare state. As all social expenditure counts equally (i.e. regardless of who beneﬁts to what extent from cash beneﬁts or social services), the analysis of aggregated expenditure data particularly does not oﬀer any valuable insights into the

underlying structures, the distributional logic or the consequences of diﬀerent types and changes of welfare state provision. The limits to a purely expenditure based analysis become obvious within in-depth investigations of the process of welfare state change. Expenditure ﬁgures are indicators that represent policy outcomes rather than policy outputs (see also Green-Pedersen, Chapter 2 of this volume). If the primary focus of interest is the political process which brings about welfare state change researchers are well advised to focus on policy outputs, as policy outcomes are inﬂuenced by a range of social, economic and political factors. In a nutshell, we may be well advised to narrow our focus, shorten causal chains and choose a microscopic approach that analyses programme speciﬁc processes and policy outputs. Long, Complex Causal Chains and Narrow Time Perspectives: Social Rights, Welfare Eﬀorts and Pooled Time Series Analysis As already outlined above, a move backwards in the causal chain from expenditure levels or changes therein (measuring a welfare state outcome) to the generosity of social rights (measuring an output) is a risky undertaking due to the many intervening variables that may aﬀect the causal relation between social rights and expenditure (see also Kangas’ and Palme’s contribution in Chapter 6, this volume). One example is the inconsistency of ﬁndings which pooled time series analyses (TSCS) of social expenditure trends for the post-1980 period have produced in terms of assumed eﬀects of partisan politics on changes in social expenditure. Relying on pooled analysis most authors have reported overwhelming evidence for a dominant autoregressive ‘level eﬀect’ and the relevance of social and economic variables. GDP growth and levels/changes of unemployment rates are the two social and economic variables which have ﬁgured most prominently in studies that have either speciﬁed annual changes in total social spending or levels of social expenditure as their dependent variable, controlling for autocorrelation by including a lagged dependent variable (Siegel, 2002; Kittel and Obinger, 2003). However, based on the results of signiﬁcance tests for partial regression coeﬃcients within multivariate model speciﬁcations, political factors should not be dismissed. Political factors may impact on social spending either indirectly or with a considerable and variable time lag.7 Both problems raise serious questions about the standard model speciﬁcations that have been used in the majority of studies using pooled time series techniques.8 Political factors may be regarded as important background variables which have a more subtle, cumulative, delayed and therefore obfuscated impact on spending patterns than economic and social need variables.

The problem is that the standard (i.e. linear and additive) pooled regression models do not take variable time lags or causal sequences into account. For example, it is important to note that increasing social need is only reﬂected in expenditure growth if social rights have not been ‘immunized’ against a growing demand eﬀect, i.e. as long as policy makers have not implemented legislative changes limiting the access to social rights or cutting back beneﬁt levels for existing groups of beneﬁciaries. From a theoretical point of view, statistically signiﬁcant partial regression coeﬃcients for social need variables in pooled cross-sectional models should be interpreted as evidence that changing social need is a signiﬁcant short-term source of expenditure changes. But more deeply rooted causes which enable the short-term sources to become visible are to be found in the more deeply rooted policy inheritance (Rose, 1990). This point deserves some clariﬁcation. For analytical purposes, levels of social expenditure at the programme level (for social transfers) can be disaggregated into one factor which reﬂects the number of claimants receiving a beneﬁt and another one which reﬂects the average beneﬁt payment (OECD, 1985). To assess the consequences of political decisions on expenditure levels the potential relevance of at least two types of policy changes is to be taken into account: (1) policy changes altering the generosity of beneﬁts (entitlements) and (2) changes aiming at reducing the number of beneﬁciaries (e.g. via changing eligibility criteria). Increasing levels of social need are translated into higher expenditure only if neither the access to nor the level of social rights is signiﬁcantly aﬀected by policy changes. If beneﬁt conditionality is tightened between two time points (Clasen and Clegg, 2003 and Chapter 8 in this volume), it is likely (and in most cases politically intended) that a lower share of oﬃcially recognized unemployed persons qualify for an unemployment beneﬁt payment. Hence the relationship between the level of unemployment and expenditure on unemployment beneﬁts changes, as soon as political interventions distort the causal chain between these two variables. However, in none of the multivariate models estimating the determinants of social expenditure changes do we ﬁnd a term which would control for changes in the conditionality of beneﬁts, as there is no crossnational time series which would provide comparative researchers with a reasonable quantitative measure of conditionality. Time series analyses of welfare eﬀorts that focus on annual changes face another tricky problem. Particularly during and shortly after economic recessions, when unemployment rates tend to increase sharply, increases in social spending are mainly a consequence of growing social need and reduced economic output, both highly correlated sources of short-term expenditure change.

Finland in the early 1990s is a good case in point. According to OECD SOCX data Finnish total social expenditure jumped from just 24.8 per cent of GDP in 1990 to 33.9 per cent in 1991. This dramatic increase mainly reﬂected a rather sharp decrease of GDP of 5.9 per cent and a doubling of the unemployment rate (from 3.2 per cent to 6.7 per cent). Clearly, the impressive increase of Finnish total social expenditure ﬁgures was not the consequence of a unique Finnish experiment lifting the generosity of welfare state provision. Instead, as Saari (2001) has shown, it was the institutional conﬁguration of the Finnish welfare state (the deeply rooted cause) and its interaction with increasing social need, combined with a severe recession of three consecutive years of negative GDP growth which led to a rapidly growing social spending share of GDP in the early 1990s. Time Sensitivity When reconsidering the results of pooled time series analysis on social expenditure trends in the post-1980 period a strong tendency to conﬁrm the (statistical) impact of socioeconomic short term factors plus a level eﬀect indicating catch-up dynamics (as well as ‘catch-down’ eﬀects) can be identiﬁed.9 The essential question is what kind of inferences can be drawn from the results of model speciﬁcations which are used to analyse annual spending changes. More variable (volatile) short-term factors may for example not decisively impact on the level of social expenditure in the long run. And the level of social expenditure at any time point t1 (the often used autocorrelation term, the ‘lagged dependent variable’) is itself a product of social, economic and political factors that have determined social expenditure at previous time points (t2, t3, . . . tn). What can be demonstrated on the basis of a comparison of the results of pooled time series cross-sectional analysis with OLS cross-sectional analysis is that the relationship between levels and changes of unemployment rates on the one side and levels and changes of social expenditure on the other is extremely time sensitive: in models estimating the determinants of short-term changes of social expenditure, diﬀerences in unemployment rate are often statistically one of the most signiﬁcant predictors of spending changes. In contrast, the level of unemployment often fails to surpass conventional signiﬁcance thresholds when levels of social expenditure are speciﬁed as the dependent variable. This shows that short-term ﬂuctuations of unemployment can cancel each other out in the long run, whereas changes in unemployment contribute to the short-term variation of social expenditure. The comparatively low number of recipients of unemployment beneﬁt – compared to the number of pensioners or health care users – in combination with the comparatively low level of unemployment beneﬁt

payments in most countries results in a rather small share of unemployment beneﬁts in total social expenditure. Hence the unemployment levels not usually belong to the most important predictors of social expenditure levels in cross sectional studies. Compared to the short and long-term relationship between the level and/or change in unemployment and levels of total social expenditure the exact opposite time structure is indicative for the relationship between demographic change and social expenditure. Leaving exceptional contexts – such as massive displacements – aside, demographic variables usually do not change dramatically from one year to another. Changes of demographic features are often of a creeping and rather continuous nature. This makes it easy for politicians to play down long-term challenges as the shortterm eﬀects of demographic changes are less visible than in the case of more volatile socioeconomic push factors. Demographic changes represent the kind of slow moving (creeping) process with potentially huge cumulative eﬀects over longer periods of time. The combined eﬀect of higher life expectancy and lower fertility rates represents the most important (domestic) challenge for the ﬁnancial sustainability of mature welfare states. But it might not be the most obvious short-term challenge for a ﬁnance minister in annual budget rounds or in the context of electoral cycles of four to ﬁve years. The tricky problem for the analysis of short-term periods is that due to the slow changes in demographic variables they usually do not come up as statistically signiﬁcant predictors of annual expenditure changes. Thinking about the core set of political factors that have regularly been used as independent variables in most quantitative studies applying expenditure data, such as the partisan composition of governments, indices for the power of trade unions, the extent of corporatist policy making, or measures of the institutional veto density of state structures, it is plausible in most contexts to assume that legislative changes unfold their eﬀects often cumulatively or with a signiﬁcant time lag between policy changes and signiﬁcant outcome eﬀects (Huber and Stephens, 2001; Castles, 2004). This further complicates the search for adequate tools to establish robust causal links between expenditure levels/changes, levels and changes of social rights and the key independent variables which plausibly may impact on spending changes. Some of the remedies suggested in the literature, for example ‘cumulative measures’ of partisan incumbency, make sense if they are used for the analysis of expenditure changes over extended time periods. A dynamic approach to analysing spending data can be simulated by regressing on changes between more distant time points, such as changes in spending levels for 20 year intervals for example (Castles, 2004). But this approach does not oﬀer a promising solution to the problem of analysing short-term changes of social expenditure (Huber and Stephens, 2001).

Also, extending time intervals causes problems as it ignores information about within-period variation for both descriptive and analytical questions. Variable Impact Chains When drawing conclusions about the relationship between political decisions (and non-decisions!) and levels/changes of welfare eﬀorts it is important to consider variable causal chains between political decisions manifesting themselves in policy outputs – such as the codiﬁcation of social rights – and their outcome in terms of expenditure eﬀects. In the best of all democratic worlds, politicians do what (the majority of) voters want them to do and achieve what they intend to achieve. In such a utopian democratic context, one may assume a perfect match between policy goals and policy outcomes. However, the relationship between voters’ preferences and government actions, just as between intentions and the achievements of governments, is more complicated. Let us assume a government has chosen to take the most common and frequent policy choice: non-decisions, i.e. the conservation of the policy status quo (Tsebelis, 2002). This choice can result in radically diﬀerent policy outcomes in terms of social expenditure. It can contribute to an increase, a decrease, or a stabilization of social spending. Only the latter case reﬂects a congruency between policy output and expenditure outcomes. However, in many circumstances it is extremely diﬃcult to specify the consequences of the hidden dominance of non-decision making in a rigorous way and to assess the consequences of political inertia. Yet for the analysis of social expenditure trends it is of crucial importance to note that political decisions and non-decisions may generate intended but also unintended (and even unforeseen) consequences. At the same time it is exactly the reason why the process of moving backwards in the causal chain, from expenditure changes (as outcome measures) to policy changes (reﬂecting outputs of the political process) and government intentions, is a highly error prone process of causal inference. The particular theoretical importance of the implication of a legislative status quo preservation of social rights becomes apparent when Tsebelis’ veto player theory (Tsebelis, 2002) is applied. The link between the number of veto players, the ideological policy distance between them and their internal congruence all aﬀect the likelihood of the preservation of the policy status quo on the one hand, and the change in social expenditure on the other hand. Yet this is most diﬃcult to disentangle since status quo preservation in terms of, for example, beneﬁt generosity can have a large, a small or no eﬀect on short-term changes in welfare state budgets. Table 4.1 presents a simpliﬁed illustration of the key argument put forward here. It shows that only in a minority of stylised contexts might a

congruent dynamic between social rights and welfare eﬀorts be expected. While the relationship between social rights and welfare eﬀorts may have been congruent during the golden age of the welfare state, i.e. reﬂecting a politically induced expansion of social rights resulting in (expected and maybe even appreciated) higher social expenditure levels, the relationship is not that clear-cut in other time periods. Social policy in ‘hard times’ (Huber and Stephens, 2001) is characterized by low economic growth and increases in social need. In such a context what might be observed is expenditure growth despite government initiatives of cutting back social beneﬁts, or preserving the status quo. Germany, in the post-uniﬁcation period (particularly 1996–98 and 2003 to the present) is a typical example of this unintended expenditure increase, indicating failed cost containment initiatives. As this example illustrates, the potential error probability of any ad hoc inferences from social expenditure dynamics to legislative changes (‘government policies’) aﬀecting welfare state generosity is very high. The Implicit Constant Causality Assumption in Social Expenditure Analysis The problems of drawing inferences from the analysis of total social expenditure using regression analysis are not restricted to the relationship between social rights and welfare eﬀorts. Standard OLS regression in the form of y (Total social expenditure) ab1x1b2x1 . . . bkxme with b1, b2 . . . bk representing partial (unstandardized) regression coefficients of social, economic and political variables are usually built on (rather implicit) assumptions about causal homogeneity (unit homogeneity, see King et al., 1994). The assumptions of causal homogeneity across space (countries) and time have been discussed in the literature on pooled analysis, as one regression coeﬃcient is to be estimated for all countries and time periods, even when ﬁxed unit and or time eﬀects models are speciﬁed (Kittel, 1999; Kittel and Winner, 2005; but see also Plümper et al., 2005). However, there is one implicit homogeneity assumption in models that formalize the relationship between aggregate social expenditure and the independent variables which has not been discussed in any detail in comparative welfare state research. As total social expenditure represents the sum of expenditure for diﬀerent programmes (or functions), and given the complex relationship between a change in a policy output – measures by an indicator such as a change of social rights – and the level of social expenditure at the level of individual programmes, is it plausible to carry out comparative

62

Measuring and analysing ‘welfare eﬀorts’

expenditure analysis at the highest level of aggregation? The relationship becomes more complex and sensitive to disturbing intervening variables if both social rights and social expenditure indicators are aggregated. Moreover, it is not only theoretically plausible but, by simple correlation analysis, can be empirically shown that the relationships between political, social and economic variables and expenditure outcomes do diverge substantially across diﬀerent social policy programmes. In other words, the relationship between variables cannot be assumed to be constant across diﬀerent social policy programmes. The eﬀect of demographic ageing as a major social need factor, for example, varies between social policy dimensions such as health care, long-term care and old-age and survivors’ pensions, and is not a major predictor of spending on active or passive labour market programmes. In a similar vein, the eﬀect of partisan politics or corporatist policy making may be diﬀerent across diﬀerent welfare state domains. This is not the place to discuss all the advantages (and some of the obvious disadvantages) of a more disaggregated approach to expenditure trends in detail. Suﬃce it to note that, over the last decade, a shift towards more cautious choices in levels of analysis can be observed as an increasing number of authors have focused on disaggregated, programme speciﬁc analyses of spending trends (Castles, 1998; 2004; Huber and Stephens, 2001; Siegel, 2002; Kittel and Obinger, 2003). Problems of Data Quality and Measurement Error In textbooks on research methods it is regularly pointed out that all data are in one way or another socially constructed. The data collected and the indicators developed by individual researchers are the end product of a social process of information gathering and standardization which, inevitably, involves critical choices. Statistical data published by national statistical authorities are no exception. Social expenditure ﬁgures, such as those published by the OECD, are the product of a complex multistage process. In the case of total social spending aggregation problems are an additional problem. It is worth pointing out some of the issues which illustrate why the quality of data and measurement consistency across countries and time are of crucial importance for comparative inquiries of welfare state change using expenditure data. As De Deken and Kittel (Chapter 5 in this volume) discuss in more detail, the need for data quality and for data consistency are crucial challenges in standardized international data sets provided by OECD or Eurostat. The point can be illustrated with reference to the SOCX dataset compiled by the OECD. One of its speciﬁc problems is the absence of spending data on active labour market measures for nine countries for ﬁve

consecutive years at the beginning of the observation period (1980 to 1984). The inclusion of active labour market expenditure data from 1985 onwards generates a statistical leverage eﬀect on total social expenditure for these OECD countries. Any descriptive, and consequently any analytical, inferences which are drawn from total social expenditure without a correction of this eﬀect are therefore seriously ﬂawed due to a severe statistical artefact. The case of Ireland provides an extreme illustration of uncorrected time series of social expenditure resulting in highly misleading inferences. For the period 1980 to 1984 the OECD has clearly marked the missing data for unemployment cash beneﬁts and expenditure on active labour market policy in Ireland. From the year 1985 onwards, the ﬁgures for Ireland are included but the OECD series does not report a statistical break in the tables for total public social expenditure. Active labour market expenditure added up to 1.5 per cent of GDP and unemployment beneﬁts to 3.4 per cent of GDP in Ireland in 1985. Hence, 4.9 per cent of the Irish GDP was spent on active and passive labour market issues in 1985! The dramatic 4.8 percentage increase of total social expenditure from one year to the next is thus not really an intellectual puzzle, but points to a major statistical problem in SOCX. Although not representative, the above example shows that the quality of readily available social expenditure ﬁgures in the most aggregated form should not be over-rated. There are good reasons not to praise OECD and ILO expenditure data sets as ‘excellent’ (Amenta, 1993: 752). Rather than interpreting them as exact measures, a more cautious approach would be to view them as proxies for actual spending levels, as ‘point estimates’ with a certain error margin.10 A misleading assumption of much quantitative research is that a national statistical oﬃces can rather easily produce ﬁgures for total spending while, at the same time, they are assumed to face problems compiling spending data for individual programmes. Exactly the opposite seems to be realistic in the context of most advanced welfare states. In countries where social expenditure is not entirely ﬁnanced out of general taxation, the collection of data involves a complex ‘bottom-up process’ which includes several (collective) actors (e.g. social insurance funds) and levels of government. The more fragmented a social security system and its ﬁnancing structure, the more diﬃcult it is to arrive at a correct overall picture, standardized for national and then for international purposes. The problem of missing data may be corrected in a technical way that enables researchers to carry out reasonable time series analysis without dropping too many observations. But studies which have used the SOCX database often fail to report adjustments which were made to the OECD

time series. Hence we have to assume that data problems were either not detected, neglected or regarded as a small issue of inconsistency, none of which is satisfactory. Breaks in time series are more than just a minor nuisance. They can cause severe problems for the assessment of changes in social expenditure in more detail. The major reason for this is illustrated in Table 4.2 which reports average changes in total social expenditure for each year for OECD democracies for the period 1980 to 2001. It shows the average annual changes for 22 OECD democracies and 21 annual changes. The average annual ﬁrst order

Figure 4.2 First order diﬀerences, annual total social expenditure, 1980–2001 change of total social spending as a percentage of GDP for 22 countries in the period 1980 to 2001 was 0.19. If we exclude the exceptional crisis years of the early 1990s (1990–93), the average year-by-year change is reduced to a marginal 0.01 percentage points. Figure 4.2 presents a histogram reporting the frequency distribution and range of ﬁrst order diﬀerences. Again, it is easy to see how small annual changes in total social expenditure ‘in normal times’ are. The frequency distribution is highly skewed as in the vast majority of observations, expenditure changes fall within a range of /0.4 per cent of GDP. In real monetary terms, this is of course considerable. However, even if a very small amount of measurement imprecision is assumed, due to the relatively small ﬁrst order diﬀerences minor problems can cause signiﬁcant problems for any inferences drawn from annual changes in total social spending. If we assume a measurement error of just 1 per cent at an average level of total social spending of 22.5 per cent of GDP (for 22 OECD countries in the year 2001), the estimated error built into spending ﬁgures is equal to 0.22 per cent of GDP. Based on well known problems of cross-national time series on social expenditure this estimate of less than a quarter of 1 per cent of

66

Measuring and analysing ‘welfare eﬀorts’

GDP appears to be rather conservative and the average measurement error is likely to be signiﬁcantly larger. The problem for short-term analyses of annual spending changes measured in total welfare eﬀorts is that the estimated measurement error built into total social expenditure ﬁgures exceeds the average annual social expenditure change for the majority of observations for the period 1980–2001. Regardless of the fact that small annual spending changes do not cause a technical problem for time series regression analysis, a substantial problem remains: advanced statistical techniques like pooled analysis rely on very optimistic assumptions about the quality of spending data. As De Deken’s and Kittel’s chapter in this volume reveals there are reasons to assume that the diﬀerence between measured social expenditure and (the theoretically expected) real levels is not randomly distributed across time and countries. Comparative researchers face time and country speciﬁc measurement deviations in total social expenditure data which violate the assumption that the dependent (left hand side) variable is not suﬀering from systematic measurement error for (time or country speciﬁc) subgroups of our sample. If one accepts that the average size of the measurement error is probably larger than the average annual spending change in most years and countries, and if it is acknowledged that the measurement error is not randomly distributed over time and across cases, one might seriously question what kind of descriptive and analytical inferences based on annual total social expenditure changes should be drawn. An alternative option to a short-term perspective focusing on annual spending changes is to extend the time periods for which changes are analysed. In many cases this can reduce the problem of small diﬀerences in the dependent variable. But it does not solve the problem of non-random country and time speciﬁc measurement bias. It also comes with a price to be paid: the further time intervals are stretched, the higher the risk that important variation of the dependent variable within the time period is lost. Again, an example may help to illustrate this. Comparing total social expenditure for Sweden in 1980 (28.8 per cent of GDP) and 2001 (29.9 per cent of GDP) one might be tempted to conclude that not much has happened to the Swedish folkhemmet in the post-1980s. However, ignoring spending ﬂuctuation between these two points means to ‘aggregate out’ one of the most fascinating periods in the post-World War II history of the Swedish welfare state, both in terms of far reaching legislative changes and in terms of dramatic spending increase (from 30.8 per cent of GDP in 1990 to 36.8 per cent in 1993) and cost containment policies. Similarly, for the same 21 year period, one would miss important developments in German social expenditure trends. (West) Germany was the ﬁrst country that managed to reduce welfare eﬀorts signiﬁcantly during the 1980s. However,

German uniﬁcation put an end to this consolidation process. The fast track uniﬁcation and equalization policy of the centre-right government under Chancellor Kohl triggered oﬀ a sharp increase in welfare eﬀorts. A macroscopic perspective which would merely compare the levels of social expenditure at the beginning of the 1980s with those at the beginning of the new millennium would miss one of the most fascinating and dramatic turns in social expenditure trends.

CONCLUSIONS This chapter has summarized some of the major advantages and pitfalls of exploring welfare state change by using historical social expenditure accounts. The discussion was embedded in the wider context of a general debate about the ‘dependent variable problem’ in comparative welfare state research. This is not the place to repeat the major points which could highlight the speciﬁc strengths and limits of expenditure based approaches for investigating welfare state change. Instead, two speciﬁc comments on expenditure analysis will be made before I move on and re-address some more general issues in comparative macroquantitative welfare state research. First, it is worth pointing out that there is more than one approach to expenditure analysis – just like there is more than one approach to a social rights based comparative welfare state analysis. This chapter has focused on issues related to ‘welfare eﬀorts’, i.e. (total) social expenditure as a percentage of GDP. However, there are alternative expenditure measures which can oﬀer insights in a variety of research contexts (see Schmidt, 1998; Castles, 2004). Decisions about which spending indicators, which levels of analysis, and which techniques of data analysis are to be used for cross-national studies of social expenditure need to be made carefully and within the context of speciﬁc research questions and designs. In any case, these choices should reﬂect the end-result of a theory guided process of decision making. Second, this chapter has argued that in many research contexts expenditure sensitive approaches can indeed oﬀer a valuable perspective for exploring welfare state dynamics. However, this ‘pro-expenditure’ pledge comes with a major caveat. A ‘spending only’ based perspective of analysis can hardly capture a full picture of welfare state change. As all (post)modern welfare states represent complex conﬁgurations, it is not reasonable to draw too many generalizations from a rather restricted set of one-dimensional measures of welfare state size. This is a particularly important point since advanced techniques of data analysis might be built on strong assumptions about the underlying structure, consistency and quality of the data to be

analysed. As a consequence, causal inferences drawn from the results of highly advanced statistical procedures such as pooled time series analysis should be interpreted with due caution. Within expenditure analysis they have tended to produce unrobust ﬁndings as several replication studies have shown (see again De Deken’s and Kittel’s contribution in Chapter 5 of this volume: Kittel and Winner, 2005; Plümper et al., 2005). This lack of robustness reﬂects a methodological interaction problem between the speciﬁc techniques of pooled regression analysis and its use in the context of crossnational expenditure data. So what are the major lessons to be drawn for researchers who wish to explore welfare state change by using advanced techniques of quantitative data analysis? The answer can be illustrated by re-addressing the debate about the ‘new’ or ‘old’ politics of the welfare state. This debate may be misleading insofar as these two theoretical paradigms may not be mutually exclusive and irreconcilable. Rather, they may be understood as, at least partly, overlapping analytical approaches which help to understand speciﬁc dynamics of welfare state change. However, what should be avoided is to let the results of macroquantitative correlates decide either in favour or against the one or the other theorem. Reducing the risk of producing methodological artefacts, triangulation may provide a more reasonable and balanced strategy. Rather than ‘topping up’ existing tools for data analysis by ever more advanced analytical techniques, there are good reasons to conclude that comparative welfare state researchers would be well advised to invest more resources in the basic infrastructure of comparative social inquiry and to develop a broader set of measures for analysing welfare state change, in particular diversiﬁed sets of indicators in the context of mixed methods approaches. The major argument for such a dependent variable focused triangulation is derived from the assumption that current welfare states represent complex conﬁgurations. The most appropriate way to study shifts in these conﬁgurations may be found in a multidimensional approach. This disqualiﬁes both too ‘narrow’ research designs and the desperate search for the most parsimonious models maximizing the explained variation in the dependent variable. If one assumes that no single method or measures can oﬀer a full grasp of the dynamics of welfare change, a strong claim for opting out of one-dimensional approaches seems the most plausible lesson to be drawn. More generally, the major conclusion drawn from focusing on key issues related to macroquantitative analyses based on expenditure data is that basic issues in and dilemmas of measuring, describing and analysing welfare state change deserve more attention than at present. Thanks to a rapidly growing body of literature, current comparative welfare state research involves more elaborate theoretical reﬂections on change and

welfare reform than even a decade ago. The lack of an explicit theory or analytical framework for the study of contemporary welfare state development was ﬁlled courageously by Pierson (1994, 1996) with his inspiring, politics centred analytical approach to understanding the logic of and limits to retrenchment processes. However, during the last ten years numerous authors have started to develop theories on welfare reform from distinct analytical perspectives. This is, for example, reﬂected in the intense debate about the explanatory strengths and weaknesses of theories of path dependency in the process of welfare state adjustment (see Jochem, Chapter 12 in this volume). The rise of the ‘new risk’ paradigm that seems to deﬁne a major fresh playing ﬁeld for sociologically inspired welfare state analysis is another example (see Bonoli, Chapter 3, this volume). In addition, new developments in macroquantitative methodology have provided comparative welfare state research with more sophisticated tools for analysing the dynamics of change. Hence one might conclude that innovations in theory and methodology suggest a bright future for comparative welfare state research. However, there are several good and one fundamental reason to be more sceptical. First, the impressive progress in new techniques of data analysis such as pooled time series cannot disguise the problem of basic issues in macrocomparative research deserving more attention than they have attracted so far. Both the development of ambitious theoretical generalizations and the impressively rapid progress in advanced research techniques are vulnerable as long as they are not built on more solid fundamentals for descriptive and analytical inferences. The production of robust, valid and reliable measures of welfare state change represents a key challenge, as the quasi ‘cement’ for any stable foundation on which empirically rooted theories of welfare reform should be built. Both robust descriptive and analytical inferences depend on adequate measures of the dependent variables that are to be investigated. The current debate on welfare state change suﬀers from a lack of a critical mass of alternative indicators to available measures of social rights and expenditure (see Scruggs, Chapter 7, this volume, for a major innovation in this ﬁeld). A major investment in the development and collection of a broader range of cross-nationally standardized indicators may not appear to be the intellectually most fascinating undertaking (academic) researchers may like to spend their time (and resources) on. However, as several contributions to this book show, investing in such a foundation of comparative welfare state research, i.e. carefully derived conceptualization and measurements of welfare state change, seems a necessary prerequisite for a promising future for comparative welfare state research. While there are numerous elaborated theoretical conceptualizations of welfare state change, as well as an abundance of

70

Measuring and analysing ‘welfare eﬀorts’

sophisticated analytical techniques, it is the missing link between theory and advanced techniques of data analysis which causes concern. If comparative welfare state research fails to bridge this gap, artless sophistication may become a chronic feature. The worst case would be a situation where ever more elaborated theoretical concepts are developed which are by and large resistant to a meaningful translation into measurable empirical concepts and where ever more sophisticated techniques of data analysis sacriﬁce the real-world complexity on the altar of simplistic model assumptions. An alternative route for comparative welfare state research would be to recouple theory and method. This path would certainly have to move well beyond a purely expenditure based approach to analyse welfare state change.

The author is indebted to Jochen Clasen, Olli Kangas and Bernhard Kittel for helpful comments on earlier versions of this chapter. The two main variables determining increases in social expenditure as a percentage of GDP for the 1990–93 period were changes in real GDP and the change in unemployment rates, both, of course, highly correlated. The situation is diﬀerent for welfare state research that is primarily utilizing micro data, e.g. household panel data. Compared to comparative macroscopic welfare state research, microanalyses often put more emphasis on measurement and conceptualization, one plausible reason being that data analysers are working more closely together with data producers in this sort of social policy analysis. The author pleads guilty to having arrived at this rather cautious and risk averse conclusion (Siegel, 2002: Chapter 12). I owe the phrase ‘assuming away’ to Peter Hall’s critical assessment of the relationship between ontology and methodology in contemporary comparative politics (Hall, 2003: 386). One of the most impressive examples is Castles (2004) as it shows that the author is not exclusively interested in arriving at some parsimonious statistical models but actually provides an in-depth exploration of available expenditure data to investigate a broad range of salient issues related to both descriptive and analytical questions of welfare state change. If it were plausible to assume that time lags between political decisions and spending outcomes were constant across countries and diﬀerent welfare state programmes, constant time lag terms on the right hand side of regression equations could at least mitigate this problem. However, it is plausible to assume that lag structures do signiﬁcantly vary in diﬀerent contexts. See also Plümper et al. (2005: 343–5, 349). Again, time lag eﬀects can be speciﬁed in pooled models, but the problem is that large lags between political decisions and expenditure outcomes cannot be dealt with in a reasonable way. For example, the full ﬁscal long-term eﬀect of major pension reforms introduced in the 1950s started to unfold only 30–40 years later and in interaction with demographic ageing. Hence, the long-term eﬀects of the pension reforms of the 1980s and 1990s can only be estimated and will manifest themselves with a time lag that is diﬃcult to specify and varies across diﬀerent old-age income systems (Hinrichs, 2001). Signiﬁcant level eﬀects may indicate that countries with lower spending levels tend to witness higher growth dynamics (usually referred to as catch-up), or that in nations with

already above average spending levels social expenditure tends to grow comparatively weaker or decreases. Both indicate what is often labelled -convergence. Beta convergence can reﬂect ‘catch-up’ (like in Greece, Japan, Portugal, and particularly remarkably, in Switzerland after 1980); but it can also reﬂect downward adjustments (catch-down) in countries which cluster into the category of high-spending nations: the Netherlands and Sweden for example (and, until German uniﬁcation, the Federal Republic between 1982 and 1989). The convergent trend in social expenditure is also reﬂected in a remarkable drop of the coeﬃcient of variation (indicating -convergence) from 0.31 to 0.21 between 1980 and 2001, i.e. a reduction by almost exactly one third. This idea is based on interviews with Paul Conway and Willem Adema, OECD, March 2005.

5. Social expenditure under scrutiny: the problems of using aggregate spending data for assessing welfare state dynamics Johan De Deken and Bernhard Kittel INTRODUCTION Since the late 1980s the governments of most OECD countries have been concerned with reorganizing their welfare states in general, and their retirement systems in particular. Through such reorganization they seek to prepare for – or hope to ward oﬀ – the ﬁnancial crisis of welfare arrangements that has been predicted for the coming decennia. Scholarly contributions have focused on the directions reforms take and the conditions under which they take place (Bonoli et al., 2000; Pierson, 2001). More speciﬁcally, cross-national research has put much eﬀort into exploring the extent to which the ideological position of governments inﬂuences the size and direction of welfare state reform (e.g. Pampel and Williamson, 1985; Huber and Stephens, 2001; Kittel and Obinger, 2003; Castles, 2004; Galasso and Profeta, 2004). In order to measure reform and change, these scholars have largely relied on the Social Expenditure Database (SOCX) of the OECD, which is considered to be the most reliable source for comparable data on social expenditure. While it is granted that, as has been repeatedly warned, expenditure data contain little information about the substantive content of welfare eﬀorts, they are generally regarded as a valid indicator of overall welfare eﬀort. The results of these research eﬀorts into the political determinants of social expenditure cannot have been more ambiguous. Kittel and Obinger have summarized a variety of studies revealing contradictory coeﬃcient estimates, depending on the period and countries included, the variables included, and the model speciﬁcation (Kittel and Obinger, 2003: 25–8). In their own analysis of the conditional impact of parties and political institutions, they ﬁnd that the largest impact results from socioeconomic factors (economic growth, share of elderly people, unemployment rates), and that 72

73

the contribution of political-institutional factors is marginal in substantive terms, although the coeﬃcients largely exhibit the expected direction and a plausible size. By excavating the detailed series of the OECD Social Expenditure Database (an eﬀort which is unusual for cross-national comparative work), Castles has found that the results also critically depend on the exact composition of the social expenditure indicators used (Castles, 2004). In this chapter, we would like to add one more note of caution. Although the OECD has put an impressive amount of eﬀort into collecting comparable data, the statistical department itself admits that some aspects are simply too complex to be represented in a consistent accounting ediﬁce. It may well be true that the Social Expenditure Database is the best we can hope to obtain. But are the best data available good enough for drawing conclusions about the direction and size of welfare state change, or – more modestly – about the direction and size of social expenditure in general and old-age pensions in particular? After scrutinizing the Social Expenditure Database and comparing it to the European System of Integrated Social Protection Statistics (ESSPROS), a database published by the Statistical Oﬃce of the European Union (Eurostat), we tend toward the conclusion that this question has to be answered to the negative. In the following, we ﬁrst explore some dimensions of the measurement problem. Subsequently we compare models of social expenditure in which we vary the deﬁnition of the dependent variable while keeping constant the substantive model speciﬁcation, i.e. using more or less the same set of independent variables. In the ﬁrst part, we will focus on the problem of measuring welfare eﬀort consistently. In order to exemplify pitfalls, we focus on a comparison between the Netherlands and Germany, where necessary referring also to some other countries for clarifying our argument and to show that the Dutch–German comparison does not represent a unique but rather a common problem of social expenditure deﬁnitions. Nevertheless, the comparison is particularly revealing, because the Netherlands, according to SOCX data, is the country with the most pronounced cutbacks in public social expenditure during the 1990s, while the OECD ﬁgures suggest roughly stable levels for Germany. We compare two databases (OECD and EU) and discuss the diﬀerences between public, mandatory private, and voluntary private expenditure. In a subsequent step our chapter will focus on problems of measuring pension expenditure. In the second part, we will use the various deﬁnitions of social expenditure in general, and pension expenditure in particular, as dependent variables in a regression model in order to explore the impact of conceptual diﬀerences on the estimated parameters. The ﬁnal part concludes.

Measuring and analysing ‘welfare eﬀorts’

THE DEPENDENT VARIABLE PROBLEM: HOW TO MEASURE WELFARE EFFORT The OECD’s Social Expenditure Database has been heralded as a most welcome tool for comparative welfare state research because it allows disaggregating total social security expenditure and thus oﬀers the possibility of taking account of the structure of social provisions (Castles, 2004). In this section, we explore a variety of measurement concepts and actual scores for social expenditure in more detail for a few countries in order to assess the extent to which diﬀerent sources of data converge on a particular statement. SOCX versus ESSPROS At the time of writing, the most recent SOCX database includes a historical series of expenditure data on 13 social policy areas for the 1980–2001 period.1 Social expenditure is deﬁned by the OECD as ‘the provision by public (and private) institutions of beneﬁts to households and individuals in order to provide support during circumstances which adversely aﬀect their welfare’. It includes cash transfers as well as direct provision of goods and services ‘provided that the provision of beneﬁts constitutes neither a direct payment for a particular good or service nor an individual contract or transfer’ (OECD, 2001: 9). A distinction is made between three broad categories of social spending: (1) public, (2) mandated private and (3) voluntary private. Public expenditure covers all levels of government (central, regional, local). However, because of the variable quality of the data, the reported government spending may be underestimated for countries where the quality of data at the lower tier of government is inadequate.2 In its deﬁnition of the public nature of a programme, the OECD has taken a diﬀerent approach than Eurostat in its ESSPROS database. ESSPROS deﬁnes schemes as public if the decision making power lies with the government in its governing capacity (and not just in its capacity as employer of state employees). The OECD, on the other hand, considers social expenditure as public only if it is made by agents of the government sector. Thus, for the OECD, expenditure is only considered public if it occurs in the context of a statutory scheme. Eurostat on the other hand also considers mandated schemes to be part of public expenditure. The two methods of calculating seem to result in quite diﬀerent assessments of cross-national social expenditure eﬀorts. The cross-national diﬀerences reported by ESPROSS are far more limited than the ones to be found in SOCX. Thus, for example, for the year 2001, Eurostat estimates

total social expenditure for the Netherlands at 27.5 per cent of GDP, for Germany at 29.8 per cent and for Denmark at 29.5 per cent (all relatively close to the EU15 average of 27.6). The OECD on the other hand reports only 21.8 per cent for the Netherlands, 27.4 per cent for Germany and 29.2 per cent for Denmark (far more spread out around the EU-15 mean of 24.0 per cent of GDP). What accounts for these diﬀerences between the two databases? Public versus Mandated Private and Voluntary Private Social Expenditure One of the reasons for these diﬀerences seems to lie in the fact that, in contrast to SOCX’s ‘public social expenditure’, Eurostat’s ‘total social protection’ ﬁgures include the costs of administrating beneﬁt systems,3 and a number of expenditure costs that the OECD labels as ‘mandatory private’ and ‘voluntary private’. The ESSPROS category ‘total social beneﬁts’ excludes administrative costs, but still seems to include most of what the OECD categorizes as ‘private social beneﬁts’. These beneﬁts form a grey area between individual non-social private beneﬁts and public social beneﬁts. In an attempt to reduce the direct responsibility of government for social expenditure, during the past decades this grey area has experienced a substantial growth at the expense of programmes directly controlled by the state. In general, private social beneﬁts refer to social expenditures that are not directly controlled by the central state, local governments or publicly regulated social security funds, but that are also not ‘established at market prices given the individual’s risk proﬁle’ (Adema, 2001: 10). Typical examples would include occupational pension plans based on a deﬁned beneﬁt basis, or health care plans ﬁnanced by employers. What is Private: a Dutch Social Expenditure Miracle? The problem though is that certain characteristics of a programme may be private, whereas other characteristics could point to their classiﬁcation as public. In this context the statisticians of the OECD give the example of Dutch pension funds. Initially the stipulations of Dutch occupational pensions were voluntary collective agreements. But those arrangements are very often enforced within an entire industry because of the widespread practice of administrative extension.4 For the OECD this implies that those arrangements could be classiﬁed as mandatory, i.e. that participation in what formally is a private arrangement is required by (quasi) law. But a closer scrutiny of the SOCX database reveals that in fact the OECD classiﬁes most of those schemes, in particular the Dutch occupational pensions, as ‘voluntary private social expenditure’. In our opinion this is a misnomer: the

76

Measuring and analysing ‘welfare eﬀorts’

Dutch government’s policy of administrative extension of collective agreements has led to an exceptionally high coverage of the working population in terms of occupational pensions.5 More than 90 per cent of the employed population are participating in occupational pension plans.6 The following arguments have been made by the OECD statisticians for justifying the labelling of the Dutch pension plans as voluntary private arrangements: (1) Dutch authorities do not have a formal inﬂuence on the terms agreed in the initial collective agreements; (2) the government can only use the tool of administrative extensions on request of the parties concerned (i.e. the trade unions and the employers’ associations); (3) most of the companies and parties were (eventually via their association) party to the voluntary initial agreement (Adema and Einerhand, 1998). Although this is a perfectly defensible position, we think it is a very formalistic and legalistic argument: by the same token one could label any neo-corporatist form of social insurance a private voluntary arrangement. One can thus only wonder why the OECD treats these beneﬁts diﬀerently from, for example, mandatory sickness payments in Germany. In the Federal Republic employers are legally required to continue to pay the wages of their employees during the ﬁrst six weeks of work absence due to sickness (Lohnfortzahlung im Krankheitsfall). The OECD correctly classiﬁes this type of beneﬁt as mandatory private expenditure. It is this obligation that forms the prime explanation for the quite high scores of this country in terms of mandatory private social expenditure. Hence it is surprising that a similar scheme, initiated in the Netherlands in 1996 when the government abolished the sickness beneﬁt insurance, is not included in the category of private mandatory in the Dutch case. Instead, it seems to have been classiﬁed as voluntary private social expenditure. The 1996 Dutch reform caused public and mandated private social expenditure, as measured by SOCX, to fall without the actual costs or generosity of sickness support in the Netherlands having changed much. Another puzzle in the OECD statistics in this regard is the size of this expenditure item. Despite the fact that the Dutch scheme mandates employers to continue to pay wages, albeit only at 70 per cent,7 for a much longer period (52 weeks instead of six weeks), the Dutch programme appears to be much more modest in expenditure terms. With an average sickness absence rate three times as high as in Germany,8 mandated expenses relative to GDP, even four years after the new system had been in place, remained well below the ﬁgures reported for Germany. Again, as becomes evident from Table 5.1, this expenditure item appears to have been classiﬁed as a voluntary arrangement in the Dutch case. But even here sickness beneﬁts appear surprisingly low, considering that the Netherlands has about three times as many beneﬁciaries of sickness

beneﬁts as Germany. Even if one adds up voluntary private, mandatory private and public social expenditures on sickness beneﬁts, the Netherlands only appears to spend 50 per cent more than Germany, with about three times as many beneﬁciaries (see Table 5.2). ESSPROS, on the other hand, seems to label both mandatory private and voluntary private programmes as ‘contractual private schemes’. It deﬁnes them as ‘providing social protection decided via bargaining between the social partners (employers and employees)’ and, what is important for the present argument, does include them in its aggregate social expenditure measure (Eurostat, 1996: 22). For Eurostat, the social nature of all these

78

Measuring and analysing ‘welfare eﬀorts’

programmes lies in the fact that they are all established by collective agreements and cannot be changed unilaterally by employers. Thus, in the ESSPROS database the social protection interventions of the following institutions are all included in its aggregate social expenditure measures: the central state, local governments, social security funds, autonomous selfadministered pension funds, insurance companies, mutual beneﬁt societies and even direct obligations by employers (to the extent that they are embedded in a mandate by the government). One would thus expect sickness beneﬁt to correspond to the last column of Table 5.1, but unfortunately this is not the case. As Table 5.2 demonstrates, Germany spends about the same amount according to Eurostat data as according to OECD data, while the Netherlands spends less if private expenditure is excluded, or more if it is included. If for Germany the ESSPROS data seem to correspond more or less with SOCX public mandatory private voluntary private, the ﬁgures for the Netherlands ﬁnd no clear match in any of the SOCX series. For pensions, this ambivalent classiﬁcation leads to a drastic underestimation of the costs of old-age provisions in the Netherlands, as becomes evident in Table 5.3. If one considers only public and mandated expenditure according to the OECD deﬁnition, one would get the impression that the Netherlands is not aﬀected by the problem of ageing: pension expenditure even declined during the period 1994–98. It is these kinds of inconsistencies, we will demonstrate, that make pooled time series analysis on available social expenditure data rather futile. Moreover, most of the aggregated data that the OECD publishes in an easy accessible way are only based on public social expenditure.

The problems of using aggregate spending data

79

the majority of comparative welfare state researchers seem to prefer to base their analysis on these very limited data (see e.g. Clayton and Pontusson, 1998; Huber and Stephens, 2001; Kittel and Obinger, 2003; Castles, 2004). At best they also include what the OECD calls mandatory private programmes. We would like to argue that in order to paint a more comparable picture of diﬀerent countries’ welfare eﬀorts, it is necessary to include mandated private social expenditure too. The OECD classiﬁcation in this respect is deceptive as, in the case of the Netherlands for example, the OECD classiﬁes mandated occupational pensions and mandated sickness beneﬁts as ‘voluntary arrangements’ (and thus leaves out all the aggregate measures published by the organization). It takes a persistent researcher to recompile aggregates from the original data sources in order to obtain an indicator that takes into account all the necessary components of social expenditure.9 The distinction between public, mandated private and voluntary private social expenditures seems of secondary importance to most comparative welfare state research. If one adopts a so-called ‘functional deﬁnition’ of the public sector (SCP, 2004), it does not matter whether the government is directly or only indirectly responsible for expenditure: all social expenditure, irrespective of whether it is ‘public’, ‘mandated private’ or ‘voluntary private’ (in the OECD terminology) has an eﬀect on the income distribution, as well as on such issues as non-wage labour costs. Provided that it is adequately operationalized and measured, the distinction between ‘public’ and ‘mandated private’ on the one hand, and ‘voluntary private’ on the other is, of course, a potentially quite important one. The distinction can have substantial repercussions for theoretically important dimensions or concepts for characterizing welfare states, such as universality, for example. By deﬁnition, voluntary private programmes are not universal, and even if embedded in a mandate by the government, private programmes remain less universal than public programmes, as the practice of occupational pensions in countries such as the Netherlands and Denmark shows. In those countries risk redistribution within the earnings related component of the pension system is limited to speciﬁc sectors or speciﬁc occupational groups. Moreover, in order to make any sensible analysis based on these kinds of nuances in expenditure accounts, spending data need to be reliable over time and classiﬁed in a consistent way across countries. The examples of social spending statistics for the Netherlands and Germany have already pointed to severe problems for two countries in this respect. Voluntary Social Expenditure and the Impact of Mandating Changes in public social security programmes cannot be fully understood without taking into account mandatory and voluntary private provisions.

80

Measuring and analysing ‘welfare eﬀorts’

This is particularly relevant if public programmes are replaced by private programmes that are mandatory. Shifts from public to voluntary programmes are less likely to reduce the total level of expenditure if such a shift occurs in the context of a coordinated system of industrial relations, as this may explicitly or de facto involve practices of mandating. Hence more centralized systems of industrial relations are said to lead to higher social expenditure than more decentralized ones (Brandl and Traxler, 2005). Again, the Netherlands is a revealing case, as during the 1990s a principle of communicating vessels seems to have been at work in this country: cuts in public programmes were quasi automatically compensated for by private arrangements, which, in the context of the Dutch system of neo-coporatist governance, were not that private after all. This resulted in only marginal changes in both social expenditure and distributional consequences. For example, cuts in the public pension scheme that amounted to a decline of about 25 per cent of the value of the beneﬁts of the basic pension scheme (Haverland, 2001) were compensated (for 90 per cent of the beneﬁciaries) by the actual and future beneﬁts guaranteed by occupational pension funds. Thus the erstwhile replacement rate of 70 per cent was maintained, regardless of the declining value of the basic pension.10 Similarly, the socalled privatization of the sickness beneﬁt insurance system in 2006 simply created a mandated scheme similar to the one which exists in Germany for the ﬁrst weeks of sickness absence. Both these policy measures caused public social expenditure, as measured by SOCX, to drop signiﬁcantly during the second half of the 1990s, while increases in mandatory and voluntary private expenditure during the same period went up by about the same amount. Thus, between 1994 and 1998 public pension expenditure (as a percentage of GDP) increased by 0.7 percentage points in Germany while it decreased by 0.7 percentage points in the Netherlands. However, the sum of mandatory and voluntary private expenditure in the Netherlands increased by 0.6 percentage points, while it remained unchanged in Germany. This means that the social eﬀort for oldage provision developed in a much more similar way than public expenditure ﬁgures for the two countries suggest, both in terms of levels and in terms of changes (see Table 5.3). A similar image has been created as a result of the much heralded reform of the Dutch sickness beneﬁt system. While total expenditure for this function in Germany declined from 1.86 per cent of GDP to 1.42 between 1994 and 1998, in the Netherlands this decline was actually weaker (2.24 per cent of GDP to 2.15). If one focused on public and the OECD’s ‘mandatory’ private expenditure, one would arrive at the opposite conclusion: only a moderate decline in Germany (from 1.86 per cent of GDP to 1.43), and a steep decline in the Netherlands (from 2.01 to 1.02).

The problems of using aggregate spending data

81

A Brief Digression on Gross versus Net Social Expenditures Both SOCX and ESSPROS are conﬁned to gross expenditure, i.e. the collected data refer to expenditure before taxes have been levied on beneﬁts. This, of course, has major implications for comparability, since a given amount of a beneﬁt not only has a very diﬀerent distributional impact depending on whether it is taxable or not, but taking account of tax levies can also dramatically reduce the volume of net expenditure. There are basically three ways in which the tax system can aﬀect social protection (Adema, 2001; Adema and Ladaique, 2005): 1.

2.

3.

direct taxes and/or social security contributions on social protection transfers (in countries like Germany, France and Belgium do not exceed 2 per cent of GDP, whereas in Denmark and the Netherlands such levies exceed 5 per cent of GDP); indirect taxes on social protection transfers (in this respect the United States diﬀers sharply from most European countries, and Scandinavia in particular, where substantial proportions of social transfers are clawed back via indirect taxes); and tax breaks for social purposes (in Belgium and Germany, such tax breaks are quite prominent for families, in the United States this is the case for medical care and for employer contributions for private health plans). Tax breaks for pensions are important in countries with funded pension plans such as the Netherlands and the United Kingdom. These include tax exemptions for contributions to private pensions as well as tax relief for investment income on capitalized pension funds. If the ﬁrst type of tax eﬀect is still relatively easy to assess, the second and the third are far more diﬃcult to calculate. The main problem with measures of ‘ﬁscal welfare’ (Titmuss, 1963) in the area of old-age pensions is the fact that tax relief can be granted at various stages (contributions, investment and capital gains and/or beneﬁts).11 Because of this diﬃculty the OECD does not consider these measures in its assessment of ‘net social expenditure’, but merely list them as a ‘memorandum item’.

Often the main problem with all three types of tax eﬀects is that the relevant information is unobtainable. Attempts by the OECD in this respect resulted in tables with many empty cells and footnotes like ‘relevant estimates cannot be obtained: either because information on gross spending for the relevant item is not available or because the information available on taxes and social security contributions is not detailed enough to present relevant estimates’ (Adema, 2001: 18).

82

Measuring and analysing ‘welfare eﬀorts’

Towards a Comparable Data Set on Gross Social Expenditure Using again the example of Germany and the Netherlands we will illustrate how we compiled the aggregate and pension expenditure measures we will be using in the subsequent analysis. We will focus on pensions for the following reasons: (1) in terms of expenditure they represent by far the most important welfare state programme; (2) it is an area that is fraught with the type of measurement problems we have been discussing up to now; and (3) it poses a number of additional problems that are related to the intertemporal nature of these programmes.12 Problems inherent in measuring pension expenditure Let us start by elaborating the third point made above. A number of problems have rarely been addressed in comparative studies of pension expenditure. One diﬃculty concerns the implications of diﬀerent designs of pension systems, in particular the extent to which national pension provision relies on funding or Pay-As-You-Go (PAYG). In contrast to popular belief, the reliance on funding does not make much diﬀerence for the longterm ﬁnancial equilibrium of a pension system or the ﬁnancial burden of the pension system for a nation’s economy (Mackenroth, 1957; Orszag and Stiglitz, 1999; Barr, 2001). Nevertheless, the use of the funded approach can, especially in the short term, severely aﬀect the comparability of the costs of national pension systems. During periods in which the returns on investment are high because of booming ﬁnancial markets, funded schemes are able to spend considerably more than they need in terms of revenue and than unfunded PAYG systems spend. On the other hand, if funded schemes are designed as deﬁned beneﬁt programmes with a back-service obligation,13 revenue will have to be higher than beneﬁt expenditure after a crisis in the ﬁnancial markets. To illustrate this point, Table 5.4 contains information on total receipts and total expenditure of Dutch occupational pensions. If this second pillar of the Dutch pensions system had been organized on a pure PAYG basis, revenue and expenditure volumes would be roughly equal for every year. But, as is evident, this is not the case. During the ﬁnal years of the speculative bubble on the stock market, the funds’ expenditure on beneﬁts was much higher than were receipts. In contrast, a few years after the stock market crash at the beginning of this millennium the situation was reversed. In order to compensate for their massive investment losses and to comply with the regulators’ requirements of a minimum funding position, the funds had to collect much more in contribution revenue than they were spending on pension beneﬁts. Thus, if during the late 1990s expenditure data overestimated the cost of ﬁnancing pension beneﬁts in the Netherlands, by 2003 the situation had

been dramatically reversed and expenditure data no longer adequately reﬂected the costs and social eﬀort.14 While up to 2001, the ratio of expenditure over receipts was above 1.0, ever since it has been sinking well below that threshold. A second problem related to the intertemporal nature of pension schemes is the way it complicates the assessment of their contribution to ﬁscal welfare. Tax breaks on occupational and individual pension plans are diﬃcult to deal with because they are aimed at yielding beneﬁts in the future. As a consequence, taxation occurs, and tax relief is given, at various stages in the savings process. Following Adema it is possible to distinguish three stages/areas where tax treatments need to be considered (Adema, 1997; 1999): (1) when contributions are paid either by employees or by employers on their behalf (this can be out of either taxed or untaxed income); (2) when investment returns are realized by the funds which can be taxed or left untaxed (even the capital itself can be liable to a wealth tax); (3) when beneﬁts are being paid to pensioners either in the form of a lump sum or as an annuity, which can be taxed or left untaxed. For all three areas one can ask the question whether the cash ﬂow consequences should be recorded, or alternatively if some sort of present value (accruals) estimate of the tax treatment should be used (Adema et al., 1996). The problem is that most countries have come to adopt the so-called EET model, in which both contributions and funds are exempt from taxation, whereas beneﬁts are taxed.15 In this case it is impossible to assess the future taxation of beneﬁts (which would correct the apparent generosity of the tax credit granted at two of the three stages mentioned above), since the future tax receipts will, amongst other factors, depend upon the ratio between pension income when retired and income from paid work when contributions are made. As we indicated above, these sorts of problems and the

84

Measuring and analysing ‘welfare eﬀorts’

resulting lack of comparable data have led the OECD to present tax relief on pensions merely as a memorandum item. But this cannot be considered to be a solution, since the exclusion of tax relief within an aggregate social expenditure measure leads to a signiﬁcant underestimation of the cost of social security. A third problem concerns the demarcation of pension expenditure. This is, of course, less of a problem if pension expenditure is merely used as one element of total social expenditure. But it can pose serious problems if the study of welfare states is disaggregated to the level of individual programmes. Both SOCX and ESSPROS list old-age beneﬁts and survivors’ beneﬁts in separate spending categories. The problem here is the degree of variation in the structure of national pension schemes, which makes the kind of distinction the OECD has suggested misleading. In some countries, for example, widows will simply be catered for by a basic pension scheme, whereas in other countries they will obtain a derived pension from the deceased male breadwinner husband. Only the country speciﬁc programme diﬀerences can explain the fact that according to SOCX data a country such as Belgium spends more than 2.5 per cent of its GDP on survivors’ pensions, whereas in Denmark the corresponding ﬁgure is only 0.02 per cent (Table 5.5). In its manual, ESSPROS points to the problem that oldage and survivors’ functions are part of a coherent set of beneﬁts ‘which is sometimes instituted as one system’ and concludes that ‘it is recommended to take into account that a strong interdependence exists between these . . . functions’ (Eurostat, 1996: 60).16 In addition, one might have to include part of the expenditure that social assistance schemes in countries like Germany pay out to pensioners who have no or insuﬃcient pension claims on their own.17 The problem is that the SOCX data do not seem to adequately measure the latter category. Given the structure of the pension system in the four countries included in Table 5.5, one would expect the row ‘Low-income assistance’ to show the highest levels in Germany, where the social assistance scheme operates as a back-up to one of the most actuarially orthodox pension schemes in the world, and the lowest in countries with generous basic pensions (such as Denmark and the Netherlands). However, we ﬁnd the opposite to be the case. Moreover, for some countries, such as Belgium, expenditure on social assistance is not even listed in the SOCX database. For other countries, the data reported by SOCX and ESSPROS again diﬀer substantially. In particular expenditure on old-age pensions in Denmark diﬀers by almost 30 per cent when the two databases are compared. The diﬀerences in the category measuring social assistance (which only partly goes to old-age pensioners or recipients of survivor beneﬁts) might be explained by the fact that ESSPROS also includes beneﬁts in kind such as

accommodation, basic services etc. In the analysis which follows we will only add the old-age and survivors’ beneﬁts (which also seems justiﬁable as the social assistance measure does not seem to perform as we expected). It seems the case that ESSPROS already includes social assistance beneﬁts for the elderly in its old-age function. That could in part explain why expenditure for this function is so low in Germany (at least in ESSPROS) and might in part account for the much higher old-age expenditure reported for Germany.18 So far we have illustrated the inadequacies of and diﬀerences between the databases of the OECD and the EU by investigating expenditure items for pensions and sickness beneﬁts. In the subsequent statistical analysis we will ﬁrst examine total social security expenditure before turning to pension expenditure. This is not only because total social spending is a central variable in most comparative welfare state research, but also as an attempt to bypass the problem of cross-national diﬀerences in terms of the functional delimitation of programmes. For example, in countries without a basic pension scheme, i.e. where the statutory scheme is more actuarially orthodox, many pensioners may see their pension beneﬁts supplemented by social assistance. In those countries, an important part of the pension bill thus may end up being footed by the social assistance scheme. By only examining the pensions function one would thus underestimate social expenditure for pensioners in such countries if compared with countries where programmes that are classiﬁed under the pension function guarantee a basic income upon retirement. Subsequently, though, we will again focus on pension expenditure, as on the basis of our analysis so far, we expect the issue of public versus mandatory and voluntary private expenditure to play a more salient role. Data Sets for Total Social Expenditure From the SOCX database, we used three series of variables that measure total social expenditure: 1. 2. 3.

SOCX public total social expenditure as a percentage of GDP; SOCX mandatory private social expenditure as a percentage of GDP; and SOCX voluntary private social expenditure as a percentage of GDP.

Most comparative welfare state research is based on the ﬁrst series, which we will refer to at as PTSESOCX. Some researchers also add to this private mandatory expenditure, which results in what we will label PMTSESOCX (Public and Private Mandatory Total Social Expenditure, i.e. the sum of

12). However, as we have demonstrated above, using the case of the Netherlands, the OECD’s category of ‘mandatory private social expenditure’ fails to incorporate important expenditure items which we consider to be part of mandatory programmes too, in particular occupational pensions which are part of collective agreements and subject to administrative extension by the government. This is the reason for introducing a third variable, PMVTSESOCX, in which we add all three categories of expenditure listed above. In doing so, we were faced with yet another problem: the series in the SOCX database turned out to be incomplete when it came to private social expenditure. For the 22 countries we include in our analysis, this (lack of) coverage is documented in Table 5.6. It is striking that it is primarily the so-called liberal welfare states which tend to be characterized by low public social spending and for which data on private voluntary spending are missing in the SOCX database. This is a

88

Measuring and analysing ‘welfare eﬀorts’

serious problem, as one would expect that in these countries, low public social spending is compensated for by voluntary private social spending. This type of social spending does not seem to be measured at all in the countries which are usually characterized as liberal welfare states. As a consequence, even our system of recoding will underestimate total social spending ﬁgures for some countries. We also use three dependent variables that express expenditure on pension beneﬁts: 1. 2. 3.

SOXC public pension beneﬁts expenditure as a percentage of GDP; SOXC mandatory private social expenditure as a percentage of GDP; and SOXC voluntary private social expenditure as a percentage of GDP.

Each of these three is actually the sum of old-age pensions and survivors’ beneﬁts. We decided to add these two programmes because of the problems discussed above, i.e. the categorization of programmes in systems of social security that are organized in diﬀerent ways.19 Similarly to our diﬀerent sub-measures for total social spending, we developed three dependent variables: PPENSSOCX takes into account only public pension expenditure. PMPENSSOCX is based on the sum of public pension expenditure and mandatory private expenditure and PMVPENSSOCX is based on the sum of public, private mandatory and voluntary private expenditure. From ESSPROS we directly took two series on total expenditures: 1. 2.

ESSPROS total social protection expenditure as a percentage of GDP; and ESPROSS total social beneﬁts expenditure as a percentage of GDP.

The main diﬀerence between these two is that the former (which in our analysis will be referred to as TSPESS) includes not only expenditure on various beneﬁts (for which we will use the label TSBESS), but also the costs of administrating the beneﬁt schemes and an item which Eurostat refers to as ‘other expenditure’. The share of the costs of administering the schemes is on average about 3.4 per cent of total expenditure. The category ‘other expenditure’ is on average less than 0.9 per cent20 and ‘usually refers to actual interest payable by the scheme to banks, and other creditors in respect of loans taken up’ (Eurostat, 1996: 35). In principle we expect that TSBESS should more or less correspond with the variable PMVTSESOCX that we derived from the SOCX database (as the OECD does not take into account administrative costs). The main diﬀerence between these two is that the OECD based variable, in contrast to the one based on Eurostat data,

also comprises expenditure on active labour market policies. On the other hand, if one looks at the health expenditure component, PMVTSESOCX only takes into account public expenditure, while TSBESS seems to be based on a broader deﬁnition that also takes into account what the OECD would call mandatory private and voluntary private expenditure. Finally we also developed out of the ESSPROS database a dependent variable measuring pension expenditure: 1.

ESSPROS pension expenditures as a percentage of GDP.

Similarly to our SOCX based variable, this variable, which we will refer to as TPENSESS, includes both old-age and survivors’ beneﬁts. In principle it should more or less correspond to PMVPENSSOCX. Table 5.7 gives an overview of all the dependent variables we will use in our analysis. Table 5.8 presents simple correlations between the dependent variable in its various conceptualizations. The lower-left part is based on the variables deﬁned in levels and reveals basically two things. First, the correlation coeﬃcients within the sets of social expenditure and pension expenditure indicators are well above 0.9.

expected given the importance of pension expenditure for total social expenditure. The upper-right part presents the coeﬃcients for the diﬀerenced variables, which refer to changes in levels of expenditure. The picture is very similar here, except for the ﬁnding that now the correlations between the social and pension expenditure indicators – ranging from 0.8 to 0.9 – are hardly lower than those within each set of indicators. There is, however, one exception, and that is the correlation between the change in total social expenditure, measured as the sum of public, mandatory private, and voluntary private expenditure and the change in other social expenditure indicators, which ranges from 0.55 to 0.72 and hence is considerably lower. Hence, we can draw two conclusions from the analysis of correlations between our diﬀerent measures of social expenditure. Firstly, the stark conceptual diﬀerences between various deﬁnitions of both social and pension expenditures appear not to matter in statistical terms, as long as the deﬁnition remains within the realm of non-voluntary programmes. This ﬁnding may be partly due to the fact that mandatory and voluntary expenditure data are incomplete and hence the variables containing these elements are in practice inconsistent. However, dropping all cases for which private expenditure data are missing leads to a correlation coeﬃcient between PTSESOCX and PMTSESOCX (NT 24) of 0.995 for levels and 0.998 for ﬁrst diﬀerences, and the ones of PMVTSESOCX with PTSESOCX and PMTSESOCX become 0.465 and 0.492 respectively. Hence the extent of congruence is remarkable because it implies that the considerable conceptual diﬀerences in measurement which we have highlighted in the ﬁrst part of this chapter appear to aﬀect the relative positions of the cases on the scales only partly. Thus, variation oriented statistical methods are unlikely to capture the diﬀerences between public and mandatory private programmes. Secondly, the congruence of total social expenditure and pension expenditure in the results for diﬀerenced variables is indicative for the importance of pension expenditure for total expenditure trends. Hence, we can expect the results to be fairly robust across these variables as well.

MODELLING ACCOUNTS OF SOCIAL EXPENDITURE USING DIFFERENT CONCEPTUALIZATIONS OF THE DEPENDENT VARIABLE In this section, we explore the eﬀect of varying the deﬁnition of the dependent variable in expenditure analysis on the substantive conclusions based on regression analysis. We expect that the considerable conceptual diversity

92

Measuring and analysing ‘welfare eﬀorts’

of the dependent variable should be reﬂected in substantive variation of coeﬃcient estimates. Our starting hypothesis is therefore the following: given the same model speciﬁcation, diﬀerences in the deﬁnition of the dependent variable should lead to substantively diﬀerent conclusions. For example, if a country shifts a welfare programme from the public to the private sector, public social expenditure should decline, but the sum of public and private expenditure should remain constant. Such manifestations of policy diﬀerences should appear in the results as diﬀerences in coeﬃcient estimates if social expenditure data are regressed on political indicators in a quantitative macrocomparative research setting. Unfortunately, there is no agreement at all in the literature with regard to the most appropriate model speciﬁcation. In the traditional welfare modelling business, there is almost unanimous consensus that it is most appropriate to deﬁne the dependent variables in levels because political and institutional eﬀects have long-term, cumulative eﬀects on social expenditure (see e.g. Huber and Stephens, 2001). This emphasis does not lend itself as easily to the analysis of aggregate retrenchment eﬀects however, since the concept of retrenchment refers to a change with regard to some previous value, not to diﬀerences between countries. Hence, in line with more recent contributions, we decided to analyse diﬀerences ﬁrst (Kittel and Obinger, 2003; Castles, 2004). If one does not focus on long-term, cumulative eﬀects on the size of welfare eﬀort but on retrenchment dynamics, this is the most adequate speciﬁcation because the dependent variable is then in fact conceptualized in terms of changes. Given the methodological focus of this chapter, we do not wish to add more complexities to the substantive discussion than necessary and hence merely draw on a long-standing debate in political economy. According to Pierson’s analysis of welfare retrenchment, the two crucial factors are the willingness of a government to embark on expenditure cutbacks and its possibilities to implement its preferences (Pierson, 1994; 1996). Hence we put partisan eﬀects and their dependency on the institutional framework centre stage in our empirical analysis. This idea has been formulated repeatedly in the literature, but according to our knowledge the ﬁrst attempt to explicitly model this conditionality is Kittel and Obinger (2003). Hence we mainly build on their approach. We use the traditional rough indicators for the ideological position of the government and institutional constraints and follow Kittel and Obinger (2003) in estimating a conditional eﬀect between the two. We control for the usual socioeconomic factors, e.g. the share of the population over 65, unemployment rates, and GDP growth (for a more detailed discussion of these ‘usual suspects’ see Castles, 2004; Siegel Chapter 4 and Kangas and Palme, Chapter 5, this volume). Furthermore, we add the lagged level of the

The problems of using aggregate spending data

93

dependent variable as an indicator of the reference point of retrenchment aims. We measure government ideology by the share of left parties in government. This is expressed as the ratio of cabinet members from socialdemocratic, green, and more-to-the left parties to the total size of the cabinet, using the deﬁnitions from Schmidt (1996). If there are few institutional constraints on policy implementation, we expect the coeﬃcient to be positive, while it should be close to zero if there are many. Institutional constraints are measured by the indicator for institutional rigidity which Kittel and Obinger (2003) have used and which is a combination of Lijphart’s indicators of bicameralism and federalism (Lijphart, 1999). The share of the population over 65 and the unemployment rate should be positively related to social expenditure while GDP growth should impact negatively on total social expenditure. The lagged level of social expenditure should be negatively correlated to the subsequent change as higher levels indicate a higher pressure to consolidate welfare systems or, put otherwise, because countries may have reached their ‘saturation level’ of social insurance (Flora, 1986a; Alber, 1987). The period analysed and the countries included are mainly determined by data availability and cover 18 countries over varying periods between 1993 and 2001.21 Before discussing the results in more detail, a few notes on crucial but diﬃcult speciﬁcation decisions are required. The ﬁrst and most ambiguous decision concerns the time horizon of welfare reform. As Pierson has impressively shown, welfare reforms are not usually eﬀectuated within one year, as the usual approaches to pooled time series cross-section analysis assume by default (Pierson, 1996; 2003). Instead, Pierson argues that the eﬀect tends to spread out over many years, and in pension policy up to about 70 years. While this is certainly true, it also overstates the issue because such a time horizon exceeds the reference frame of both political actors and citizens. In principle, any mid-term period should reveal some, at least initial, eﬀects of welfare legislation if it is meant to be serious. However, variation in eﬀect lags across countries, periods, and programmes and therefore makes any attempt to capture eﬀects by one average coeﬃcient impossible. Here we opt for a pragmatic intermediate solution and analyse two four-year intervals, 1993–97 and 1997–2001, which both cover periods of intense debate over welfare reform in OECD countries. This period is also bracketed by data availability for the dependent variables. Secondly, we have lagged the explanatory variables by one year in order to leave one additional year for eﬀects to take oﬀ. Hence the models are estimated on a two-wave panel, deﬁning the dependent variables in changes from 1993 to 1997 and from 1997 to 2001. The lagged levels are taken from 1993 and 1997. Changes in the share of the population over age 65 and

94

Measuring and analysing ‘welfare eﬀorts’

changes in unemployment rates refer to the periods 1992 to 1996 and 1996 to 2000. GDP per capita growth is the average growth rate for 1992–96 and 1996–2000. Left government is deﬁned as the average share of government seats of social-democratic, socialist, and green parties 1992–96 and 1996–2000. Institutional rigidity is constant over the whole period of analysis. We used a panel setup with time eﬀects and estimated the models using OLS. Given that due to our operationalization of the time dimension, there are just two waves for the ﬁrst diﬀerences, autocorrelation can hardly be consistently estimated. But since we analyse diﬀerences ﬁrst, we do not expect this to be a serious concern, given previous ﬁndings with longer time series (Siegel, 2002; Kittel and Obinger, 2003). Total Social Expenditure: SOCX vs ESSPROS Table 5.9 compares the models estimated for four diﬀerent deﬁnitions of social expenditure, as deﬁned and explained above. As far as the substantive model speciﬁcation is concerned, three critical notes should be made. First, the share of the population over 65 is negatively, though statistically insigniﬁcantly, associated with social expenditure. Sensitivity analysis reveals that this is due to the inclusion of the lagged dependent variable, which contains the level eﬀect of the share of the elderly population. Secondly, changes in unemployment, included in accordance with the expectation that increases in unemployment rates would generate a push eﬀect on social expenditure, do not signiﬁcantly correlate with social expenditure changes – a ﬁnding that is equally puzzling. Furthermore, the interaction analysis reveals that under the condition of high institutional rigidity, left government is even negatively associated with social expenditure. This supports the Nixon-goes-to-China logic based on a party systems explanation as suggested by, inter alia, Kitschelt (2001) and Ross (2000b). According to this proposition leftist governments are in a better position to cut back welfare programmes than parties to their right because they are the natural pro-welfare state party and therefore may credibly claim that, regardless of restrictive saving measures, they still have a vital interest in preserving generous welfare state provision. But ﬁndings in favour of this proposition remain fairly ambivalent (Kittel and Obinger, 2003). Apart from these somewhat puzzling details, the models turn out to produce astonishingly robust results. In particular, we ﬁnd a clear conditional eﬀect of partisanship and institutional rigidity, a clear negative eﬀect of the lagged levels of social expenditure, and a clear negative eﬀect of GDP growth. Jointly, these variables capture about 60 per cent of the variation in the dependent variable, a number which is even more impressive in

the face of a complete failure of those factors which carry the largest explanatory load in models using annual data (Kittel and Obinger, 2003). More disconcerting in methodological terms, however, is the ﬁnding that our results do not depend on the deﬁnition of social expenditure. This

96

Measuring and analysing ‘welfare eﬀorts’

implies that although we use fairly diﬀerent deﬁnitions, which causes considerable divergence in the measures, this variety does not appear to aﬀect the substantive conclusions we might infer from these models. One implication drawn from this might be to emphasize the robustness of the results regardless of diﬀerent model speciﬁcations. However, in our view this is a completely faulty interpretation because it means that our statistical analysis is simply unable to account for serious diﬀerences in measurement: although we measure considerable shifts in the composition of social expenditure which should be attributable to government activity, there is no indication in our ﬁndings that these shifts matter, although our study revealed clearer and more robust indications than previous studies that government policy mattered, even during the 1990s (cf. Huber and Stephens, 2001; Kittel and Obinger, 2003). Since we were unable to obtain data for voluntary social expenditure, or for pension data beyond 1998,22 we have to shift the period analysed somewhat in order to assess these variables. Therefore, in Table 5.10 we present a variant of the analysis performed in Table 5.9, in which the ﬁrst diﬀerence period has been shifted to 1994–96 and 1996–98. Compared to Table 5.9, the story told by this table does not seriously diverge from the longer time span, except for a clearly worse overall ﬁt, and generally smaller and less statistically signiﬁcant coeﬃcient estimates.23 However, the results for the new variable included, PMVTSESOCX, are striking. While the ﬁt of the socioeconomic variables appears to be much stronger, the politicalinstitutional interaction model, which contributes most to the ﬁt of the other models, breaks down for this variable. This is most relevant, because it hints at the potential need to nuance the conclusions about the impact of these factors. Apparently, the political factors we use do diﬀerentiate between diﬀerent levels of public eﬀort in social protection but are not related to the voluntary part. At the same time, to the extent that the public eﬀort seems to underprovide for social protection, voluntary programmes are used to compensate for the missing part, thereby jointly matching societal demand, which is captured by the included socioeconomic variables. Pension Expenditure: SOCX vs ESSPROS In order to facilitate comparisons, we use the same model speciﬁcation for the analysis of pension data (Table 5.11). Comparing the results we ﬁnd that the model overall performs considerably worse. The overall ﬁt drops substantially, hardly any coeﬃcient estimates remain statistically signiﬁcant, and the political-institutional interaction eﬀect gets lost in the noise, although its basic structure remains intact. Note that the eﬀect of change in the elderly population now has the expected direction – even though the

eﬀect only seems to be relevant for the SOCX public expenditure data. At the same time, the diﬀerent pension indicators do not entail diﬀerent results, apart from minor and irrelevant variation in coeﬃcient estimates. This ﬁnding is surprising. Given the high correlations between social and pension expenditure data, the degree of divergence in the results is astonishing, but also in line with earlier surprises arising from our analysis.

Comparing Tables 5.8, 5.9, 5.10 and 5.11, there are three major ﬁndings. Firstly, diﬀerences in conceptualization appear to be invisible in the actual research setting. Neither does it matter which elements are included in social or pension expenditure, nor whether the variable is consistently measured or not. The correlations within the sets of social expenditure and pension expenditure variables are extremely high and the substantive interpretation

99

of the model remains unaﬀected. Secondly, the four-year dynamics in total social expenditure are fairly well captured by the model (Table 5.9). In particular, we ﬁnd the expected conditionality of the partisan eﬀect on the institutional setup of the polity. Shortening the sub-periods, however, leads to a reduction of the model’s explanatory capacity, albeit without curtailing the conditional eﬀect (Table 5.10). Thirdly, despite the high correlations between the indicators of social and pension expenditure (well above 0.8), a comparison between tables 5.10 and 5.11 reveals that the same model employed for the two sets of indicators yields considerable diﬀerences in model ﬁt, although the general picture remains unchanged.

CONCLUSIONS By discussing measurement and modelling issues in the quantitative macrocomparative analysis of social expenditure data, we have highlighted a variety of serious methodological problems, which are rarely considered in customary research in this tradition. We should note, moreover, that these problems are certainly not unknown or even new. Their appreciation needs careful scrutiny of the lengthy, complicated, and not easily available technical notes to the datasets. We summarize our ﬁndings and conclusions in a tabular form. The ﬁrst problem is that even our best sources for internationally comparable data (the OECD social expenditure database and the European Union’s ESSPROS database) are conceptually ambivalent and inconsistent to an extent which seriously undermines the conceptual validity of the indicators used. We have discussed the Dutch case, where the aggregate data does not cover mandatory private pension programmes. If such inconsistencies occur in one country for which we happen to have information, how can we rely on measures for other countries? A second problem is the fact that, despite the impressive amount of work done by the data collecting organizations (OECD and EU), many indicators have missing values for many observations, in particular at the more disaggregate level. This raises the question of the trustworthiness of the aggregate measures, for which more complete time series for longer periods and more countries are available (see also Siegel’s discussion of aggregation problems in Chapter 4, this volume). This problem is often due to the lack of data. For example, there are hardly any data on voluntary pension plans which exceed legal requirements in Belgium. A third and related concern involves measurement diﬀerences between data sets which are often considerably larger than diﬀerences over time. Hence the uncertainty about the exact score of a country at a certain point

100

Measuring and analysing ‘welfare eﬀorts’

in time is larger than the measured changes over time. Since the measurement error may be larger than the measured variation, our ability to interpret the results of time series analyses is seriously undermined (again, see also Siegel’s contribution to this volume). Fourthly, even within data sets, the comparability of observations between countries and over time is compromised by changes in concepts and measurement errors or the inconsistent application of measurement concepts. In addition, diﬀerent methods of measurement make speciﬁc types of expenditure appear higher or lower than they are in reality. As a ﬁfth concern we have noted in passing that ﬁscal policy constitutes another major stumbling block for assessing the actual magnitude of public welfare eﬀorts. This relates to the whole area of tax regulation for pension programmes, family policy, education, but also applies to a variety of welfare- and income-relevant issues such as social housing policy and mortgage deductibility regulations. Since such measures form a heavy burden on the public purse and have considerable redistributive eﬀects (though often to the beneﬁt of the better-oﬀ), they should in fact be included in a functional deﬁnition of welfare. While data on these issues are practically unavailable on a cross-nationally comparable basis, it can safely be assumed that their size and hence their distorting eﬀect for comparative measurement is more substantial than all the observed diﬀerences between indicators including public, mandatory, and voluntary welfare programmes (see Obinger and Castles, 2006). The ﬁnal concern in this certainly not all-encompassing list is that in some, albeit important, respects, the above problems appear to matter only marginally in quantitative macrocomparative research. There is too little and too much variation in outcomes at the same time. We ﬁnd that using conceptually diﬀerent indicators of either social expenditure or pension expenditure – public versus public plus private mandatory – as a dependent variable leads to practically identical parameter estimates. While one might applaud this result as proving the robustness of the results produced by diﬀerent model speciﬁcations, in our view it is more indicative of the problem that the method employed is insensitive to important conceptual diﬀerences in the measurement of indicators. Even if we accepted this as a sign of robustness, we would be faced with another problem: pension data are a major element of social expenditure and hence should be closely related to the latter. They do indeed correlate strongly with social expenditure, but substituting the former for the latter leads to a substantial decline in model ﬁt. Hence, conceptually divergent indicators converge in outcomes, while conceptually related indicators diverge in outcomes. All of the above concerns may be regarded as a debate about half-full and half-empty glasses. However, in our view the problems jointly highlight a

serious methodological fallacy which is inherent in the usage of social expenditure data as indicators of welfare eﬀorts and which contributes to the dependent variable problem. As we have shown, a close and detailed examination of the data allows the extraction of information about ongoing shifts in the composition of social expenditure, which may plausibly be attributed to governmental retrenchment policies. Such a careful tracing of the implications of policy decisions for expenditure data, however, is quite the contrary to the large strokes of quantitative macrocomparative analysis ‘rigorously testing’ broad hypotheses about partisanship, institutions, and socioeconomic determinants. They simply miss these subtle shifts due to the enormous amount of noise in the data. Nevertheless, and despite all these concerns, there are some indications which may support a more positive conclusion. Firstly, our selection of examples may overemphasize the problems. The selection of countries for our analysis is due to our prior knowledge of particular cases for which we are able to compare the data contained in the data set to other sources of information. Hence we cannot claim to have presented a representative sample.24 Secondly, it is not inconceivable that many measurement problems may be solved in future versions of the data sets. Conceptual ambiguity, missing data, and erroneous classiﬁcations are not irresolvable problems, although their solution may take considerable further eﬀorts. Thirdly, and perhaps most intriguingly, the little information we have on the diﬀerences in ﬁndings for public and total social expenditure tells an interesting story: politics seems to be able to account for variation in public spending, but not for variation in total spending, including voluntary expenditure. At the same time, socioeconomic factors tend to be more closely related to total spending than to public spending. This suggests the existence of communicating vessels: private provision substituting for public provision in case the latter is more restrictive. Hence the measures for total expenditure seem to follow societal needs, as measured by the socioeconomic indicators in the model, more closely than public programmes alone. But this interpretation is based on a very weak foundation: the measures which we used for total social expenditure are seriously distorted by conceptual ambiguity and missing information, particularly for those countries in which voluntary programmes cover relatively larger parts of the total welfare eﬀort, and by the weakness of the ﬁndings, which are to a considerable degree based on the interpretation of statistically insigniﬁcant results from a fairly simple model covering little variation in a small data set. Finally, our explanatory model is far from complete. The eﬀects which we identiﬁed may thus be distorted due to missing variables. Most importantly, future research should elaborate the empirical analysis of two

102

Measuring and analysing ‘welfare eﬀorts’

potentially important factors which we have noted in passing in the course of our argument, but did not include in the model speciﬁcation. The ﬁrst is the extent to which collective agreements aﬀect the dynamics of welfare arrangements such as collective pension plans or sickness funds. There are basically two mechanisms which lead collective agreements to aﬀect the size of such programmes. Firstly there is the share of trade union members in employment (union density) and the share of employees covered by legal extension clauses. We have not dealt with these issues here. The second factor is related to the developments in the capital markets: if the cycle of the capital markets diﬀers from the cyclical development of social development (which can be induced by, for example, demographic and by labour market developments), funded schemes can in the short run either perform better (when the returns on capital markets grow faster then social expenditure) or worse (when returns on the capital markets grow slower than social expenditure). In case of the ﬁrst type of development, funded pension schemes may appear momentarily less costly than PAYG arrangements. It is thus particularly relevant to control these factors in time series analysis where the consideration of the timing of eﬀects becomes relevant. Hence, our overall conclusion is that while political scrunity is reshaping the welfare state, this process goes largely unnoticed by analysts who attempt to draw big conclusions from all-encompassing models without scrutinizing the technical annexes of the data sets which they use. To simply turn back to business as usual and to continue estimating one regression equation after the other on the same ambiguous aggregate data seems, in our view, fairly careless. We have a serious and – at least currently – insurmountable data problem, which curtails our ability to discriminate between contending hypotheses. Thus, despite all hopes and many endeavours to the contrary, we have not yet completed the phase of careful data collection, which, to a considerable extent, will have to be based on systematic, in-depth, comparative case studies, exposing us to the plight and dust of archives. The time of elegant models is yet to come in comparative welfare state research.

However, due to missing data, in practice one must settle for considerably shorter periods. For example, expenditure statistics at the municipal level in Belgium are much less detailed than at the federal or regional level. According to Eurostat these costs amount on average to about 3.5 per cent of expenditure in the European Union. Austria scores the lowest with 1.5 per cent while the Netherlands scores the highest with 4.7 per cent. The Minster of Labour declares a collective agreement generally binding for all employees working in an entire sector of the economy.

Interestingly enough, in its discussion of replacement rates in its 2005 Pensions at a Glance (OECD, 2005c), the OECD considers Dutch occupational pensions to be private mandatory schemes. In the US, by contrast, this applies to only about half of the working population, although this country is usually considered to be the reference case for widespread occupational pensions. In some collective wage agreements this is increased to 100 per cent. Employers can privately insure this risk of having to continue to pay wages for this, by international standards, very long period. During the period 1983–2001 this was on average 4.1 per cent in the Netherlands, and only 1.4 per cent in Germany, which in both countries was also the ﬁgure for the year 2000 (see Figure 1 and Table 1 in Sisko Bergendorﬀ Sickness Absence in Europe – A Comparative Study, 4th International Research Conference on Social Security, ISSA, Antwerp 5-7 May 2003, available at www.issa.int/engl/publ/2contanvers.htm). Even then one is faced with the problem that SOCX is sometimes ambiguous as to whether data are just missing or the value is actually zero. The shift from the public to the mandatory private scheme, though, may lead to inequalities in the future, as the 70 per cent replacement rate that the occupational schemes seek to achieve is only a convention, i.e. it is not backed up by law. Moreover, the method of ﬁnancing these beneﬁts can diﬀer substantially between the diﬀerent industry-wide and enterprise based pension funds. In some cases the employers bear most of the costs; in other cases it is the employees. The funds diﬀer also substantially in terms of their policies towards survivor pensions etc. In other words, the shift from public to mandatory private schemes does seem to imply important consequences in terms of the pooling of risks. For an overview of these arrangements in the European Union, see Fédération des Experts Comptables Européens (2001), Aspects of Taxation of Occupational Pensions in the EU, Brussels (available at www.fee.be/publications/main.htm). See also Chinu Patel (ed.) (2004), Taxation of Occupational Pensions in EU Countries, Oxford: European Actuarial Consultative Group. These would also form an increasing problem for other programmes, such as disability schemes if they were run on a funded basis. Like in a pay-as-you-go scheme, a funded deﬁned beneﬁt scheme guarantees its pensioners predeﬁned beneﬁts, irrespective of the investment performance of the pension fund. In case of disappointing investment returns or of investment losses, these deﬁcits have to be compensated for (‘back-serviced’) by increased contributions to be paid by the current and future sponsors of the plan, without resulting in corresponding higher beneﬁts for future retirees. This is also illustrated by the steep rises of contribution rates that the world’s second largest pension fund, the Dutch ABP, implemented during this period: from 13.2 per cent in 2002 over 15.2 per cent in 2003 to 18.6 per cent in 2005 (an increase unheard of in any PAYG system) The only exceptions to the EET rule seem to be some occupational pension arrangements in Germany and Luxembourg. This interdependence also refers to a third function, that of disability. Similar problems exist regarding early retirement pensions, which in some countries are primarily ﬁnanced via the unemployment insurance system (e.g. Belgium), while in other countries they are primarily classiﬁed as a cost for the pension system (e.g. in Germany). In the absence of a statutory early retirement arrangement, incapacity beneﬁts can even act as a functional equivalent (e.g. the UK). The ESSPROS manual deﬁnes ‘old-age pension’ as ‘periodic payments intended to i) maintain income of the beneﬁciary after retirement from gainful employment at the standard age or ii) support the income of old persons. This could also include social assistance beneﬁts for the elderly’ (Eurostat, 1996: 58). Some early retirement beneﬁts are not included, in particular ‘early retirement for labour market reasons’ which in the SOCX database is classiﬁed in the category ‘unemployment’.

Measuring and analysing ‘welfare eﬀorts’ A similar coding problem applies to disability pensions, which in most countries form a separate category for those whose working capacity is reduced before reaching the statutory retirement age, but in Denmark largely fall under the category ‘old-age cash beneﬁts’ (SOCX category 1.5.1, which in the Danish case includes expenditure on pensions to those who become incapacitated before reaching the statutory retirement age). It ranges from about 0 per cent in Scandinavian countries over about 0.2 per cent in countries such as Germany to 1.7 per cent for Belgium and the Netherlands. The countries which are available in both data sets and which hence are included are the European countries Austria, Belgium, Germany, Denmark, Finland, France, Greece, Iceland, Ireland, Italy, Luxemburg, The Netherlands, Norway, Portugal, Spain, Switzerland, Sweden, and the United Kingdom. Although the database contains data up to 2001, this is not the case for these series. In passing we note as a potential implication of the ﬁnding that the longer periodization leads to a better ﬁt that a sensible conceptualization of time horizons of eﬀects may indeed matter more than is usually acknowledged in panel studies using annual data. Still, how many cases are allowed to contain serious measurement errors before we stop being able to use the data without distorting results?

6. Social rights, structural needs and social expenditure: a comparative study of 18 OECD countries 1960–2000 Olli Kangas and Joakim Palme INTRODUCTION What has driven the expansion of welfare state expenditures? Why do some countries spend more on social security than others? These basic questions have occupied social scientists’ thoughts for decades. Over time researchers have come to shift the focus both geographically and in terms of level of aggregation. Cutright (1965) and Wilensky (1975) started out by analysing cross-sectional variation in social expenditure among industrial as well as developing countries. The focus was then shifted to the variation in expenditure among the most advanced industrial nations, and the variation over time within nations was also empirically analysed (e.g. O’Connor and Brym, 1988; Pampel and Williamson, 1989; Hicks and Swank, 1992; Huber and Stephens et al., 1993; Hicks and Misra, 1993; Huber and Stephens, 2001; Castles, 2004). Another shift occured when researchers started to examine the development in speciﬁc programmes such as pensions (Pampel and Williamson, 1985; Palme, 1990; Huber and Stephens, 1993), sickness beneﬁts (Kangas, 1991), family beneﬁts (Wennemo, 1994; Ferrarini, 2006), unemployment insurance (Carroll, 1999) and social assistance (Nelson, 2003; Kuivalainen, 2004). Yet comparative research in this area has still remained surprisingly inconclusive. The importance of economic development and party politics has, for example, been given very diﬀerent weights as an explanatory factor. The same applies to the more current ‘welfare state retrenchment’ or the ‘new politics’ of the welfare state literature, where results are even contradictory (see Pierson, 1994; Green-Pedersen, 2000; Korpi and Palme, 2003; Castles, 2004; Siegel, 2005). There are at least three, as we see it, fundamental problems that have contributed to this state of aﬀairs, where theoretical controversies persist and 106

107

empirical research shows only a few signs of accumulation. The ﬁrst problem is to do with the fact that researchers who have analysed the causal factors behind welfare state growth usually have not distinguished between the two diﬀerent types of factors that, both over time and across nations, produce variations in expenditure: the extension of social rights, on the one hand, and the growth of needy populations, on the other hand (for exceptions, see Saunders and Klau, 1985; Alestalo and Uusitalo, 1992; Castles, 2004). This has led to what we see as the second problem: a misconception of how politics is likely to inﬂuence welfare state variation. While it is diﬃcult to deny that social expenditure is in many ways an important indicator of welfare state development, it is more diﬃcult to recognize why politicians would be inclined to increase expenditure as such; a more likely motive would be to improve social rights and the well being of citizens. As a response to this, researchers have attempted to compile data sets on legislated social rights which can be used as alternatives to expenditure data. The results from analysis of these data suggest that variation in social rights cannot be explained in the same way as social expenditure, and, in particular, that the relative importance of political factors is sensitive to the operationalization of the dependent variable. When analysing public social expenditure, the impact of political power constellations is harder to verify (e.g. Castles, 1982a; Castles, 2004), whereas studies based on social rights as the dependent variable indicate that politics does matter (DeViney, 1983; Myles, 1984; Pampel and Williamson, 1985; Korpi, 1989; Esping-Andersen, 1990; Palme, 1990; Kangas, 1991; Wennemo, 1994; Carroll, 1999; Montanari, 2001; Huber and Stephens, 2001). Our hypothesis is that these divergent results can be explained by the combined eﬀects of structural ‘need’ variables, such as the age structure of the population and the unemployment rate, and factors related to social rights, such as the extension of the coverage of social beneﬁt schemes, earnings replacement levels, and qualifying conditions regulating access to beneﬁts. Since most ‘need’ factors are hard to alter through political decision making, the volume of social spending is not directly linked to political variables, yet is greatly aﬀected by other phenomena. For example, the relative size of the aged population has substantial ramiﬁcations for spending on pensions, as shown by Pampel and Williamson (1985; 1989). In the case of pension rights the impacts of demography are more negligible, while the impact of political factors is more pronounced (Myles, 1984; DeViney, 1984; Palme, 1990). Another good example is the proportion of children to the total population versus the level of child allowance. The share of children is harder to change by means of political decisions – or rather, the impact takes a couple of decades to become visible – than the amount given in child beneﬁts, which can be adjusted overnight.

108

Measuring and analysing ‘welfare eﬀorts’

This suggests that social rights and expenditures can be explained somewhat diﬀerently. It also indicates that neither an approach stressing structural variables nor a research strategy based on the concept of social rights alone will appropriately capture the determinants of cross-country diﬀerences in the level of social security spending. This is important when we try to understand the expansion as well as the retrenchment of the welfare state. The third fundamental problem is one of measurement. Due to the easy availability of published data, the proportion of gross domestic product (GDP) spent on social security has generally been used as the indicator of welfare state development. As discussed by De Deken and Kittel (Chapter 5), as well as Siegel (Chapter 4) in this volume, there are considerable inconsistencies within and between available statistical data sets.1 The purpose of this chapter is to contribute to the discussion sketched above by analysing the relative importance of factors pertaining to structural need and social rights respectively, in explaining the variation in social expenditures in 18 OECD countries between 1960 and 2000. In order to do this eﬀectively, it has also been necessary to address the measurement problem. Here, it is important to consider the obvious diﬀerences in available data sets, as well as how and to what degree the achieved results are contaminated by the peculiarities of the data used. An additional aim of the analysis is thus to highlight some of the methodological problems with comparative welfare state research. The research design is displayed in Figure 6.1. In this chapter we are interested in the relationships indicated by solid arrows. However, at the end of this chapter, we cursorily touch upon the issues between party politics, overall levels of social rights and social spending. The structure of the chapter is as follows.

DATA Social Rights Data on social rights have been compiled within the Social Citizenship Indicator Program (SCIP) conducted at the Swedish Institute for Social Research, Stockholm University (for a more detailed description, see Korpi, 1989; Esping-Andersen, 1990; Palme, 1990; Kangas, 1991; Wennemo, 1994; Carroll, 1999).

notion about the sequential enlargement of citizenship rights, refers to legislated social provisions aimed at guaranteeing citizens’ economic welfare and security (Marshall, 1950: 11; Korpi, 1989). Since the growth of social rights has come about as a result of modern social policy, and eligibility for beneﬁts is established in legislation, the data collection is limited to statutory or ‘public’ welfare programmes.2 Hence, when calculating the quality of social rights, we concentrate upon schemes characterized by being created via national legislation or involving direct public participation in ﬁnancing – various private alternatives or functional equivalences have been neglected. The time span for which data has been collected stretches from 1930 to, for the purpose of the present chapter, 2000 – as a rule, with observation points at ﬁve-year intervals. The countries included in the data set are Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Sweden, Switzerland, the United Kingdom, and the United States. The data set consists of information on ﬁve main social security programmes: old-age pensions, sickness insurance, unemployment insurance, work accident insurance, and family allowances.

Measuring and analysing ‘welfare eﬀorts’

Since work injury insurance in many countries is coordinated with sickness insurance, we did not analyse it separately here. For each scheme, we have information on the degree of its coverage (the proportion of those who are in principle entitled to beneﬁts); the qualifying conditions regulating access to beneﬁts (minimum membership of a scheme, length of contribution period, residency criteria, income/means testing etc.); the number of unpaid waiting days (for sickness, unemployment and work injury beneﬁts); the length of the beneﬁt period (for sickness, unemployment and work injury beneﬁts); and the amount of beneﬁt paid. Beneﬁts are calculated for a number of ‘typical’ cases with regard to earnings of an ‘average production worker’s wage’ in manufacturing; household composition (single person and four-person family with one wage earner/couple in the case of pensions); and the length of work incapacity (relevant for sickness, work injury, and unemployment. In these cases beneﬁts are separately calculated for one week and 26 week absences). Child allowances are only calculated for a family with two children (aged two and seven) and with one full-time working parent earning an average industrial worker’s wage. Beneﬁt levels for each year in each country have been related to this wage level in order to make the provisions more comparable over time and across countries, i.e. beneﬁts are proportional and the yardstick is the average wage level in industry. Since beneﬁts were previously non-taxable income, but are taxed today with few exceptions, it is necessary to take the eﬀects of taxation into account. Therefore, net beneﬁts – that is, beneﬁts after taxes and social security contributions – are related to the net wage (for details of taxation, see Palme, 1990: 26–36). Structural Needs In order to systematically examine the ways in which diﬀerent aspects of social rights, certain structural ‘needs’, and social expenditures are associated, the following sections oﬀer separate analyses for old-age pensions, sickness insurance, unemployment insurance, and child allowances. Needless to say, structural factors aﬀecting social spending diﬀer across programmes (see for example Saunders and Klau, 1985: 101–11). For oldage pensions the most important structural variable is naturally the relative size of the elderly population. This demographic pressure is measured as the proportion in the total population that is 65 years of age and over. In a similar way, a natural proxy for the ‘need’ for child allowances is the proportional size of the younger population which is measured as the proportion of persons below 16 years of age in the total population.3 In a parallel fashion, the unemployment rate can be assumed to reﬂect the ‘need’ for unemployment beneﬁts. Unfortunately, it is more diﬃcult to ﬁnd structural

variables with a direct impact on the ‘need’ for sickness cash beneﬁts. There are some sporadic data mainly based on various surveys for some countries and for some points in time, however no comparable data are available for the whole time period and for all the countries we are interested in. In the absence of a direct and more reﬂective indicator, we have used life expectancy as a proxy for the overall health status of the population. Data on structural factors employed in the subsequent analyses are mainly derived from OECD publications.4 Although our data on social rights date back to the 1930s, the present inquiry is restricted to the period 1960–2000, as reliable data on disaggregated social expenditure are only available from 1960 onwards. The points in time for which we have data are 1960, 1965, 1970, 1975, 1980, 1985, 1990, 1995 and 2000. Social Expenditure Data on social expenditure are available from various sources. The three main historical databases used in previous studies have been compiled by ILO, OECD, and parts of Flora’s extensive project (e.g., 1986a, 1986b, 1987a). Although the last data set is the most detailed and one appears to be the most reliable and consistent of the three, the problem is that it only covers 12 Western European nations, and ﬁgures are only available up to 1980.5 In order to include all of our 18 advanced OECD countries and the years for which we have social rights data, only the ILO and OECD data sets are applicable.6 Only ILO data are disaggregated by expenditure categories that best correspond to our measures of social rights by programme. The problem with the ILO data is that there may be huge discrepancies between consecutive years in the spending levels within a single spending category. OECD also provides data on social transfers where transfers are broken into separate spending categories. Crosschecking against Flora and various national sources suggested that OECD data are more consistent with the other databases. A closer examination of ILO statistics also revealed that occasionally very large changes compared to previous years appear without clear explanations to clarify why. Unfortunately, use of OECD data also leads to problems. The OECD has compiled various social spending data sets. For example, the ﬁrst data set covers the period 1960 to 1980 and the most recent one 1980 to 2001/02. The problem is that the overlap between these two time series is not perfect. The correlation between the overall spending levels is 0.71 for 1980 data. In order to improve the comparability of data, in some cases we have been obliged to make our own adjustments to OECD and ILO ﬁgures and in some cases complemented them with national data (see below). These adjustments were also motivated on a conceptual basis. In some cases the

112

Measuring and analysing ‘welfare eﬀorts’

SCIP, for example, classiﬁes sickness wage continuations schemes as ‘public’ (legislated and obligatory), whereas the OECD has excluded them. The consistency between individual expenditure categories is sometimes, but not always, better. Both the ILO’s and OECD’s disaggregated pension expenditure are rather divergent (r0.64 in 1980). For other disaggregated expenditure categories, the available statistics are more consistent. The overlap of OECD sickness data with ILO data is surprisingly good (0.90 in 1990). The greatest discrepancies appear in the cases of Austria, Germany and to some extent Finland and Norway. Both of these statistics show extremely high values for Sweden, with the spending rate at over 4 per cent of GDP compared to 2 per cent or below for the other countries. This calls for some clariﬁcation. The discrepancies between the databases are due to the diﬀerent treatment of legislated wage continuation programmes and the inclusion of varying types of cash provisions. In the Austrian, German and Norwegian cases, the ILO statistics exclude wage continuation programmes in which the employers bear the burden for all payments. In the Swedish case, both data sets include cash provisions for purposes other than income maintenance (e.g. compensation for health care, travel expenses, medicine etc.) which makes Sweden a clear outlier compared to the rest of the OECD countries. In the following analyses, expenditure on the legislated wage continuation practices in Austria and Germany have been added (as in Flora’s data). The Norwegian, Finnish and Swedish ﬁgures have also been recalculated. Our data for the two former countries, obtained from statistical reports for the Nordic countries (various years), also include the two-week wage continuation schemes which are obligatory for employers. Derived from national statistical abstracts (various years), Swedish data refer solely to sickness cash beneﬁts. In the case of child allowances, spending ﬁgures are available from the ILO database for 1960–98 and from the OECD for 1980–2002. In 1995 the correlation coeﬃcient between the databases was 0.79. The discrepancy is due to the fact that OECD data also include some other transfer categories. Since the ILO ﬁgures are conceptually closer to our measurement of the generosity of child allowances, we rely here on ILO data. However, since the ILO data have some breaks in the statistics for Switzerland, the Swiss spending data are taken from the OECD.

METHOD7 To examine whether the eﬀects of the explanatory on the dependent variables have changed from one time point to another, we ﬁrst examined annual cross-sectional data and performed separate regression analyses for each of the four social insurance programmes for each of the six cross-sections.

Here, we used ordinary OLS regressions. To make more eﬃcient use of our data, we also pooled the nine cross-sections. In other words, the data were merged and these pooled data were analysed as a panel which provides multiple observations for each country in the sample. By pooling data we receive additional information on the variation between countries as well as over time (see e.g. Hsiao, 1990; Hicks, 1994; Micklewright, 1994). There are a number of regression techniques available to deal with the particular problems of analysing pooled data – and not so surprisingly, each of them has its weaknesses. The results also seem to be sensitive to the speciﬁc method applied (see e.g. Hsiao, 1990; Beck and Katz, 1995; Kittel, 1999; Huber and Stephens, 2000). In this study, it is neither necessary nor possible to go deeper into these methodological problems. By using cross-sectional analyses (and simple visual scatter plots, which are not presented here due to space limitations), and combining them with pooled regression data, we aim to explore the relationships between social rights and social spending. However, in order to test the robustness of our ﬁndings, we conducted a number of alternative analyses. We began with a model assuming, seemingly unrealistically, that there is no autocorrelation; thereafter, we tested a model with panel speciﬁc autocorrelation and combined both of these runs with and without panel level heteroskedastic error models. By and large, the results were the same, however the standard errors and levels of signiﬁcance varied, which had some implications for our political variables. Models with no autocorrelation produced highly signiﬁcant results for the political variables, whereas models with autocorrellation tended to produce larger standard errors and, in some cases, led to statistically non-signiﬁcant eﬀects for the same variables. Pooled regressions were run by the Stata 9 (Stata, 2005: 226–35) cross-sectional time series package using Prais-Winsten regressions on correlated panels and corrected standard errors (PSCE). To deal with autocorrelation, we could have used lagged variables, in which case we would have lost the eﬀect of the level variables and our results would have been more dependent on the short-term changes (Huber and Stephens, 2000). In order to avoid this, we chose the approach outlined above. The research strategy applied in this chapter represents an analysis in successive steps. First, simple bivariate plots for each cross-section were made, succeeded by OLS models for each year. In the third step, various pooled cross-sectional regression models were estimated and, ﬁnally, the results were compared with each other. Due to space limitations, only PSCE estimates (panel speciﬁc autocorrelations and panel level heteroskedastic errors) are displayed in the tables that follow. The results from various control runs which produced signiﬁcantly diﬀerent results are discussed brieﬂy. Again due to space limitations the cross-sectional results are not shown for each year but rather for each decade of the observation period. As our cases do not

form a sample of any deﬁned universe, statistical signiﬁcance tests should be treated only as a heuristic device for evaluating the results obtained.

spending rates according to the OECD data. The index of social rights was constructed as follows: quality measures8 were calculated for each social security programme, separately transformed into standardized z-scores,9 and added together. There are diﬀerent stories to be read from the ﬁgure. If we ﬁrst look at the social rights index, we can see a remarkable growth dynamic from the early 1960s to the mid 1970s. During that period the so-called Scandinavian welfare model – high social rights attached to high social spending – emerged. Secondly, there was an increase both in social rights and spending levels which, since the 1990s, has become steady in many countries. Taken together, there seems to be a ‘growth to limits’ (Flora, 1986a, b), and a transition from an expansionist welfare state to a recalibration of social policy. Thirdly, there is a clearly positive and signiﬁcant relationship between the level of social provisions and spending, but the relationship is far from perfect. On the one hand, high spenders do not necessarily guarantee the highest levels of social rights. On the other, the low spenders rarely provide higher levels of social rights. We have countries – such as Sweden – that are on top when it comes to social rights and spending levels, but there are also countries such as Denmark, Germany, and France that display low social rights relative to their levels of spending (since the 1990s). Some other countries score relatively high on the social rights index, and are nevertheless among the medium or low spenders, as exempliﬁed in 2000 by Norway, Finland and the Netherlands. Therefore, the overall association between the index of social rights and social spending is only moderate (r0.63 in 2000). The picture essentially does not change if we use OECD or ILO data solely on social insurance expenditures (r0.33 and r0.55, respectively for all 18 countries in 1990). This indicates that social rights alone cannot properly explain the cross-country diﬀerences in social expenditure. We must also consider structural needs as a cause for the variation in this expenditure. Analyses where social expenditure rates have been regressed on the total index of social rights (as described above), and on the structural needs measured as standardized unemployment rates, the size of the elderly population, the percentage of those 16 years of age or below and life expectancy, produced statistically signiﬁcant positive coeﬃcients for both levels of social rights and the size of the elderly population. The role of the share of children is negligible. As indicated by the variance explained, the model performs less well in the most recent observations, which suggests more ‘noise’ aﬀecting social spending levels. The most important factor in all of the cross-sections seems to be the level of legislated social rights. In the pooled analysis (where various control runs produced more or less congruent results) the growth of the elderly population, increased longevity,

116

Measuring and analysing ‘welfare eﬀorts’

levels of unemployment and social rights are important factors. Longevity has no impact in cross-sectional inspections, whereas it becomes signiﬁcant in the pooled analysis. In a way, this is a logical result if we keep in mind that cross-sectional diﬀerences between countries are not that big, but that in all countries life expectancy has increased and consequently the average number of years on pension also increased, as most elderly people take home a public pension. As we have been able to improve the comparability of the data for some of the individual social security programmes, it can be assumed that the disaggregated expenditure data reﬂect diﬀerences in both structural needs and the generosity of social rights among countries more accurately than aggregate data. In the following subsections, we have therefore broken down data for both expenditure and social rights in order to examine the relative importance of social rights and structural factors and, in addition, the relative importance of diﬀerent aspects of social rights. Unemployment Insurance When it comes to determinants of spending on unemployment protection, the unemployment rate is the most obvious structural need variable. For social rights indicators, we have used the compensation level/replacement rate (proportion of previous wage), duration of beneﬁts period (in weeks), coverage (insured/labour force) and the number of uncompensated waiting days in unemployment insurance. Table 6.2 displays results from regression analyses of unemployment insurance expenditures. When explaining the growth of income maintenance expenditures on unemployment compensation, Saunders and Klau (1985: 105–09) pointed to two important determinants: the level of unemployment and the generosity of the insurance scheme. Both factors also turn out to be the most crucial ones in our regression models. The impact of the level of unemployment is statistically signiﬁcant in six of the nine cross-sections, while the eﬀects of the replacement level are not that strong in the cross-sectional analyses (signiﬁcant in four of the years). At several time cross-sections, the insurance coverage rate also has a signiﬁcant impact, but its relevance is somewhat weaker than that of the replacement level and the unemployment rate. In addition, the inﬂuence of duration is, in some cross-sections, positive (in 1990 and also in 1985 and 1995, which are not displayed in the table) and seems to grow in importance towards the end of the observation period. The increasing relevance of duration mirrors the fact that the increase in unemployment during the late 1970s and early 1980s resulted in increases in longterm unemployment spells relative to total unemployment.

example, Belgium, Ireland, Italy, and the Netherlands reached the point where over 50 per cent of their unemployed had been out of work for 12 months or more (see e.g. OECD, 1990: 13–15, 203). Previously labelled as having low unemployment, in the 1990s the Nordic countries, and Finland and Sweden in particular, presided over steeply rising unemployment rates. By 2000 overall unemployment levels had decreased, although long-term unemployment remained high. There have been calls for ‘activating’ the unemployed, including a tightening of qualifying conditions and increasing the number of days in waiting. However, as indicated by all equations in Table 6.2, the length of the waiting period is not that decisive (although it has a negative sign) when it comes to spending levels.10 The same goes for the other system characteristics. Only in the pooled data set are coeﬀecients for the quality of beneﬁts signiﬁcant. The most important explanatory factor seems to be the level of unemployment, suggesting that changes in unemployment have put the strongest upward pressure on expenditures. The overall performance of the model improved from the early 1960s up to the late 1980s, whereafter it decreased. Sickness Insurance Unlike with unemployment insurance, old-age pensions and child allowances, it is almost impossible to point to a single structural factor which has an impact on sickness insurance expenditure. Firstly, the potential target group (that is, the sick) is impossible to deﬁne as simply as the retired, children, or the unemployed who are potentially entitled to old-age pensions, child allowances and unemployment beneﬁt respectively. Secondly, comparative analysis has shown that changes in the age composition of the population tend to lead to an increase in sickness absenteeism, particularly costly long-term absences from paid work (Kangas, 1991: 124–7). Thirdly, the eﬀects of structural ‘need’ factors are not directly transformed into compensated absenteeism, but are ﬁltered by national sickness insurance and other social insurance programmes. Programme characteristics determine whether these eﬀects are strengthened or weakened. The relative impact of the structural needs and the characteristics of the sickness insurance schemes is evaluated in Table 6.3. Life expectancy, pertaining to the health status of the population, yields insigniﬁcant coeﬃcients with varying signs in cross-sectional analyses. Thus, it may be that there is an underlying trend towards higher rates of sickness absence despite the improved health status of the population (Bäckman, 1992). As expected, the replacement rate has a positive eﬀect, increasing the impact on expenditures; the impact is also signiﬁcant in all of the crosssections. The result is fortiﬁed in the pooled analyses. Thus, the quality of

Measuring and analysing ‘welfare eﬀorts’

the beneﬁt is the most crucial explanatory factor for the variation in spending on sickness allowances. As in the case of unemployment insurance, the length of the beneﬁt period (duration) also has some importance, although the coeﬃcients are not signiﬁcant in cross-sections but they are signiﬁcant in pooled data. Contrary to expectation, the number of waiting days has only a minor and statistically non-signiﬁcant negative impact on the spending rate in cross-sections. The results reﬂect that the heavy costs of sickness, which are caused by long-term illnesses, are not especially sensitive to incentive structures created by uncompensated waiting days. The results presented in Table 6.3 are based on the adjusted ILO spending data as described above. If we perform identical analyses for unadjusted ILO and OECD ﬁgures as done for the year 1990, the results are not strikingly diﬀerent. In the uncorrected ILO and OECD data the eﬀects of duration are stronger. This is mainly due to the extreme Swedish ﬁgures: an unlimited beneﬁt period coupled with an extremely high level of spending. Pensions As most studies (e.g. Wilensky, 1975; 2002) indicate, in the case of pensions the characteristics of the population may be the most important structural factor. Table 6.4 shows the results from analyses where pension expenditures are regressed on the proportion of elderly in the population (persons 65 years and over/total population), life expectancy and a number of pension rights variables. The coverage of the old-age pension scheme denotes the sum of entitlement and the recipiency rates; the former refers to the proportion of insured persons in the total population between the ages of 15 and 64, while the latter pertains to the percentage of those above normal pension-age who actually receive old-age beneﬁts (Palme, 1990: 32). Basic security11 refers to the level of minimum security guaranteed to the elderly, while income security12 measures the adequacy of earnings related pensions. In cross-sectional analyses, the size of the aged population has a signiﬁcant eﬀect on the spending volume as a rule, and the estimates from the pooled analyses are strongly signiﬁcant (regardless of the model speciﬁcation), while life excpectancy is signiﬁcant only in the pooled time series speciﬁcation. The two variables pertaining to replacement rates are only occasionally of importance in the cross-sectional regressions, whereas only income security is signiﬁcant in the pooled analyses. Various control runs yield rather similar results. If we use ILO spending data, the importance of income security is accentuated, and it is clearly more important than the level of basic security. In sum, the robust message coming out of these unrobust results is that the quality of the pension has an important eﬀect on the spending levels; however, in comparison to the demographic

factors, the qualitative indicators are slightly more marginal. Contrary to other variables, coverage also remains insigniﬁcant in the pooled analyses, indicating that cross-country diﬀerences in spending levels cannot be properly explained by diﬀerences in that dimension. This may be seen as an eﬀect of the convergence in coverage of social insurance programmes (Montanari et al., 2006). All in all, the results in this section suggest that both the size of the elderly population and the adequacy of pension rights have a substantial impact on the extent of cross-national variation in public pension expenditures. Moreover, the results suggest that needs are somewhat more important than rights when considering the size of the elderly population. The results from the pension analyses again reﬂect the problems involved in using diﬀerent existing statistical data sets. They indicate that when discussing and comparing results from diﬀerent studies, we must always carefully consider the contamination caused by measurement diﬀerences and errors in the data sets. The same label on an expenditure category given in the statistical source does not guarantee that the concepts are phenomenologically equivalent, as De Deken and Kittel show in Chapter 5 of this volume. Child Allowances In the case of child allowances, the number of waiting days or the duration of the beneﬁt period is not relevant, as is the case for unemployment or sickness insurance. Therefore, when analysing the determinants of public outlays on families, the only variable that reﬂects the extent of legislated social provisions is the replacement level of family related allowances (allowances/net average industrial wage). The structural need variable pertains to the proportion of children below 16 years of age in the population. Table 6.5 shows that the beneﬁt generosity is clearly the most decisive explanatory facor in the cross-sections and the variance explained is very high at the beginning of the period, but then it begins to decrease towards the year 2000. Interestingly and somewhat surprisingly, the need variable has statistically signiﬁcant impacts on expenditures only in a very few crosssections. The quality of provisions paid seems to be the most important explanatory factor for cross-country diﬀerences over time and in explaining cross-sectional diﬀerences.

presented in this study suggest that rights and needs both make a contribution in explaining the variation in overall social expenditure levels. The results from the analysis of individual insurance programmes show that the relative importance of structural needs and social rights related variables diﬀers. In the area of unemployment beneﬁts, the unemployment rate has clearly become the most important factor more recently. Hence, levels of unemployment beneﬁt expenditures have become more needs driven than in the past. Also, regarding old-age pensions, the age structure of the population is an important determinant of cross-country diﬀerences in expenditures, while the structural variables seem to play a less important role in explaining diﬀerences in expenditures on sickness insurance – this partly reﬂects the fact that it is hard to ﬁnd precise health indicators which could be used as needs proxies for this beneﬁt type. The relative importance of diﬀerent dimensions of social rights also varies among programmes, and for diﬀerent points in time. As a rule, the replacement level is signiﬁcantly and positively associated with spending levels, particularly in family beneﬁts and pensions (in pooled time series analyses). The duration of the beneﬁt period plays a marked role for sickness expenditures and, since the mid 1970s, also for unemployment provisions, reﬂecting the increase in long-term unemployment. With the possible exception of unemployment, the importance of coverage is marginal for spending levels. The length of the waiting period tends to dampen expenditures on sickness insurance, but the impact is weaker. Our review of the existing statistical data sets indicated that in some cases, there are remarkable inconsistencies in data that greatly contaminate the results achieved. Hence, the choice of a database partially dictates the results. This suggests that, especially if we are operating with disaggregated data, we must consider extremely carefully whether our observations on the dependent variable are comparable over time and across countries. Although various structural inﬂuences can be seen to be beyond political control, this is not necessarily always the case: family allowances may aﬀect the birth rate; improving living standards for the elderly by providing public pensions may increase life expectancy and hence the size of the elderly population; and the unemployment rate may be aﬀected by national political strategies, to give just a few examples. The case of unemployment insurance, in particular, illuminates the complex interplay between political decision making, structural needs, and social spending. A number of studies on the political determinants of unemployment rates have shown that rates are lower in countries with left-wing dominance (Korpi, 1991), whereas some later developments in the unemployment rates (particularly the increases in unemployment in Sweden and Finland) may challenge this view. Our study shows that the most important single

Figure 6.3 Politics, social rights and social spending in 18 OECD countries, 1960–2000 factor aﬀecting spending on unemployment provisions is precisely the unemployment rate. Therefore, if the links between partisan politics and unemployment are not clear-cut, it is not all that surprising that analyses of the relative signiﬁcance of political mobilization for expenditure levels tend to produce inconclusive results. This suggests that while structural factors in previous periods of welfare state development might have been largely exogenous, there is evidence to suggest that they, in some areas, have become at least partly endogenous. This is illustrated in Figure 6.3 which shows the connections between politics, social rights, structural needs and spending on social security. In principle there are a number of ways to oprerationalize political variables. Firstly, we could use cabinet seats occupied by each political block (in our cases left-wing parties, denominational parties and secular non-socialist parties); for example, consider the seats for the preceding ﬁve-year period of each year

126

of observation, or secondly we can construct cumulative scores to catch the long-term incumbencies of political power relations (Huber and Stephens, 2000: 329).13 The ﬁve-year averages would capture the immediate (or short-term) eﬀects of policy making, whereas the cumulative scores capture the impact of longer political hegemony. As most social policy schemes have their own inbuilt inertia we decided to follow Huber and Stephens (2000) and concentrate on the long-term eﬀects and use the cumulative index of political power. In a pooled regression model, where social expenditure is regressed on all the dependent variables and where political variables pertain to the accumulated power, there seems to be some impact from confessional parties on spending, while left-wing dominance has a stronger tendency to increase spending. Both left-wing power (highly signiﬁcant) and the relative strength of confessional parties (signiﬁcant) are positively linked to the generosity of social rights. The demographic factors are not related to politics, and their impact on spending levels, when the relative roles of the other factors are controlled for, is highly signiﬁcant. Thus, all in all, in the ‘end product’ – social security spending rate as a percentage of GDP – the impact of these diﬀerent factors is blurred in such a way that the relative importance of politics is more diﬃcult to establish than that of social rights, which are the objects of political decision making. It is the task of future studies to analyse in more detail how political and structural approaches can unravel the interplay between social rights and various factors of need. However, this study indicates that previous contradictory results regarding the relative importance of policy related factors for levels of social spending can partly be explained by the use of poor data and the lack of attention to the independent eﬀects of structural ‘need’ variables. Our discussion also highlights the fact that the use of diﬀerent statistical sources can lead to diﬀerent results and conclusions. To further complicate the picture, Richard Titmuss’ (1974) classical division between social, occupational and ﬁscal welfare is worth keeping in mind. Social welfare pertains to legislated social policy. Most oﬃcial statistics, such as published by the ILO or OECD, primarily contain data on this aspect of social policy. In addition, our deﬁnition of social rights is based on legislated ‘social’ welfare. Although this aspect is the most important part of income maintenance, it is not the only one and in some cases the concentration on legal rights to public provision gives a distorted picture of welfare state realities. In many countries with ﬂat-rate or low-level earnings related beneﬁts, occupational schemes have mushroomed to complement the gaps in compensating income loss. Danish and Dutch pensions are good examples in this respect (see also Jochem, Chapter 12 in this

A comparative study of 18 OECD countries 1960–2000

volume). In both countries the statutory pensions are not tied to the claimant’s previous income. Therefore, a huge occupational and ﬁscal/ individual pension sector has evolved. The same pattern is visible in sickness beneﬁts where employers guarantee sick-pay provisions on various scales. There have been a number of attempts to measure the total level of social spending (e.g. Adema, 1999). These measurements accentuate speciﬁc points that have important ramiﬁcations for exercises like ours. Firstly, diﬀerences in total public and mandatory private spending are much smaller than diﬀerences in public spending on welfare. Secondly, it makes a signiﬁcant diﬀerence whether we use gross spending ﬁgures – as we did here – or net ﬁgures. Usually big spenders, such as Denmark and Sweden, have big taxes; as a result, there is a claw-back eﬀect whereby the gross spending of 30 per cent of GDP or so is reduced to 20–25 per cent, which is not drastically more than what small spenders de facto spend on their total social budgets. Changes in the taxation of social beneﬁts may have important consequences for our understanding of the developmental patterns in social rights. For example, the generosity indicators of public pensions showed a downward trend from the 1980s. This trend has been taken as an indication of the demise of pension rights. It is important to separate declining replacement rates caused by real or nominal cuts in beneﬁts as such, from those that are due to changes in taxation. In some cases absolute improvements in pension beneﬁts do not result in increased replacement levels but rather the opposite. It is also the case that a number of countries, among them Sweden, recorded increased replacement rates in the early 1980s as a result of poor real-wage developments, which, with the then existing beneﬁt formulas, meant that earnings in earlier years boosted replacement rates calculated in relation to the ﬁnal wage. And when real wages later started to grow, this was ceteris paribus translated into declining replacement rates. Thus, if we look at the totality of social spending or welfare eﬀorts, the big-spending ‘social-democratic’ welfare states are perhaps not as superior at providing social security as they are usually believed to be, and the lowspending ‘liberal’ countries are perhaps not ‘as bad’ as usually argued. Consequently, the social-democratic welfare states are not as expensive, nor the liberal welfare states as cheap, as often claimed. At the end of the day, the advanced rich countries seem to use roughly the same amount of their GDP on the three forms of welfare. In spite of similar spending levels, distributional consequences are greatly divergent (see e.g. Kangas and Palme, 2000). Therefore, the measurement and analysis of diﬀerent aspects of social rights – preferably supplemented by analyses on occupational welfare – oﬀer very valuable tools for understanding the qualitative diﬀerences in public and private provisions of social welfare.

Statistical concepts are not comparable among countries, as data, to a great extent, follow country speciﬁc institutional arrangements. Nor are data reliable over time within single countries; in some cases methods of measurement undergo substantial changes from one observation point to the next. Despite the evident awareness among comparativists of the deﬁciencies in available statistics provided by international organizations such as the ILO and the OECD, surprisingly little as been done to reduce the measurement error. An additional problem is the distinction between gross and net spending (Adema, 1999); for example, the Nordic countries may be big gross spenders but, since they also tax social transfers, their net social spending is not always higher than it is in other European countries. The SCIP database thus excludes all labour market based collective and individual insurance programmes. Hence, in social protection areas where collective schemes are common – as with collective pensions and sickness beneﬁts in various forms of wage continuation – our measures do not give a full picture of social protection. Therefore, the level of ‘real’ social protection for countries that rely on ‘social policy by other means’ (Castles, 1989) in their social security production is underestimated. This especially applies to the Antipodean countries and also to many other countries. For example, legislated pension rights and sickness beneﬁts are much more generous in Sweden than in Denmark. However, if we take into consideration that most Danish employees are covered by lavish occupational pensions schemes and sick pay (100 per cent of income), the diﬀerences between these Scandinavian countries will disappear, or Denmark may display higher overall social security levels than Sweden. Thus, the picture we are able to draw here is fragmentary and by no means complete. Currently, we neither have suﬃcient data on private individual and occupational social beneﬁts nor on the spending on these items. However, the statutory pension age varies across nations, and due to ﬂexible retirement schemes the average retirement age has been falling in most of the OECD countries (OECD, 1988: 77–82). In many countries early retirement takes up a considerable part of total pension spending. The age limits also vary in family allowance programmes (see e.g. US Department of Health and Human Services, 2005). Therefore, the measures used in this study must be regarded as more or less accurate proxies of the demographic pressures aﬀecting spending rates. Historical Statistics (various years), Labour Force Statistics (various years), and for life expectancy: Financing and Delivering Health Care (OECD, 1987) and www.mortality. org. In addition, decomposing expenditures into separate variables of diﬀerent insurance programmes on the basis of the Flora data is not always straightforward. The reason is that the compilation of data has followed country speciﬁc institutional variation rather than ‘a variable approach’ where the national ﬁgures have been standardized to make them comparable across nations. Figures provided in the Flora database were used to cross-check the reliability of the other statistical sources in the early 1980s. In the 1980s the correlation coeﬃcients for total social spending were .77 for Flora-ILO; .82 for Flora-OECD, and .89 for ILOOECD. In the case of pensions, correlations were as follows: Flora-ILO: .52; FloraOECD: .86; ILO-OECD: .64. The corresponding ﬁgures for unemployment were .92; .92 and .93; for sickness .76, .82 and .71; and for child beneﬁts .93, .95 and .73. In previous analyses (e.g. Saunders and Klau, 1985; Flora, 1986a; 1986b; 1987a; Alestalo and Uusitalo, 1992), determinants of growth in individual programmes have been broken down into three broad categories: (1) the demographic ratio, which refers to changes in the proportional size of the population that is in principle entitled to beneﬁts; (2) the coverage ratio, which denotes to what extent the potential beneﬁciaries are actually in receipt of allowances; and (3) the transfer ratio, which pertains to the increases in beneﬁt levels. We have data on (1) and (3) but not (2), which made it inappropriate to

apply their approach. Moreover, we have an underlying purpose for using the regression technique for testing other kinds of hypotheses in another context. The quality of unemployment insurance and sickness insurance refers to the sum of the replacement rates plus coverage. The quality of child allowances refers to the replacement level, while the quality of old-age pensions consists of coverage, basic security, and income security (cf. Palme, 1990). The compositions of the indices are deﬁned in more detail in the main text. Z-scores rather than raw data were applied in order to avoid problems caused by diﬀerences in scales used to measure various aspects of social rights. The variable was signiﬁcant (sig..004) only in pooled regessions without autocorrelation assumptions. Coeﬃcients for all the other variables were almost the same, whereas there were some ﬂuctuations in signiﬁcance. However, the interpretation is precisely the same. Basic security refers to the pensions that are guaranteed for elderly people without work records or with only a minimim contribution record. In a way it is the level of the minimum safety net guaranteed in a country for a pensioner without other means (Palme, 1990: 34). Income security is the sum of three components: worker pension, full pension and maximum pension. The quality of the worker pension has been calculated assuming that the claimant has worked 35 years on an average industrial worker’s wage. The full pension level is calculated in the same way as the worker pension, only now the claimant is assumed to have worked the maximum number of contribution years required in the qualifying conditions. The maximum beneﬁt level has been calculated assuming that the pension recipient has worked for the maximum contribution period, and has an income at the maximum level taken into account for beneﬁt purposes (though no more than 1.25 times the average industrial worker’s wage in cases where no ceiling exists – Finland and Italy in a few of the years). Period averages for cabinet participation were calculated as follows: when we explain for example social rights for 1960, our political variables pertain to average cabinet shares of left-wing, denominational, secular, non-socialist and green parties in government during the period 1956–60; respectively, politics during 1961–65 is used in the regressions for the levels in 1965. The cumulative scores for cabinet participation are the sums of cabinet shares held by various political blocks since 1946. The score varies from 0 to 11. For example, ‘0’ for left parties indicates that the party block has never had a position in the government, whereas ‘11’ indicates that all of the cabinet chairs in all of the years were occupied by ministers belonging to left-wing parties. In practice the left-wing score varies from 0 in the US to the highest value of 8.81 in Sweden. The interpretation of index values for other political blocks is the same.

Beyond spending: welfare state generosity, social rights and obligations

7. Welfare state generosity across space and time Lyle Scruggs INTRODUCTION Comparative analyses of welfare state reforms have relied overwhelmingly on public spending data as the indicator of welfare state commitment and change. However, scholars have long emphasized the problems with spending outputs and also stressed the importance of programmatic elements of welfare state policies. One particular focus has been on national commitment to social citizenship rights. This general line of research has oﬀered few alternative measures that are compatible with comparative analysis across many countries and long periods of time. Those that do exist, such as the Social Citizenship Indicators project at the Swedish Institute of Social Research, are not generally available to scholars (see Kangas and Palme, Chapter 6, this volume). This has led to two reinforcing cleavages in welfare state research: largen comparisons of many countries testing general theories but relying on spending data as proxies of welfare state generosity (or eﬀort), and smalln comparisons with sui generis data sets that propose and demonstrate, but seldom really test, hypotheses. Both sides of the cleavage are subject to speciﬁc scientiﬁc limitations and advantages. For its part, the ‘large-n camp’ focuses on honing a well developed (if not uniform) set of empirical data to test analytical models and theories, but may be consistently misspecifying what the welfare state is. The more qualitative camp, by contrast, can often claim a more nuanced set of concepts, but lacks quantiﬁable leverage for scientiﬁc veriﬁcation, or, in the case of single country studies, any direct comparisons. Qualitative researchers are probably right about aspects of conceptual validity, but the quantitative approach is probably right about the requirements for theory validation. By both being half right, both approaches cannot help but be half wrong. Moreover, neglected in both approaches is the construction of valid empirical measures of concepts that are to be tested. Qualitative research generally fails to get beyond deﬁning the concept and applying it to a case 133

134

or two, thus failing to direct research to comparable, systematic data collection. Quantitative research often fails to get beyond the technical aspects of the empirical analysis, thus failing to ask whether the most used, or available, data sets are worth analysing in the ﬁrst place (see also Chapter 2 by Green-Pedersen in this volume). Collecting comparable data on non-spending aspects on welfare state programmes is an important step in bridging this gap. Such data can add fundamentally to the evaluation of changes in welfare state policy. One of the main goals of this chapter is to introduce and discuss one data set, the Comparative Welfare Entitlements Dataset (CWED), which details changes in the major components of key social insurance programmes in 18 countries from the 1970s to 2002. The other major goal of the chapter is to suggest ways in which data collection eﬀorts on ‘qualitative’ dimensions of the welfare state should be augmented in order to promote the development of more general theories about welfare state development and change. The rest of the chapter is divided into ﬁve sections. The next section addresses why cross-national and historical data sets of social entitlements are necessary in order to think theoretically about welfare state change. This section also critiques the widespread use of comparative spending data. The third section presents the CWED data on trends in social insurance programmes. The fourth section develops a beneﬁt generosity index, based on a reﬁnement of Esping-Andersen’s popular decommodiﬁcation index, and using the data presented in the third section. The evidence in the third and fourth suggests that welfare states became more generous during the 1970s and 1980s, but experienced some considerable retrenchment in the 1980s and beyond. That retrenchment has been greatest in the more generous countries. The ﬁfth section acknowledges that the CWED data set is incomplete, discusses possibilities for expanding it and, reinforces the central theme of this volume: the importance of reliable and systematic data in developing and evaluating explanations of welfare state development and change.

public policy research almost goes without saying: comparative analysis requires multiple objects of comparison. Nevertheless, many ‘comparative’ studies focus one country, or even one programme in one country. The value of this latter type of approach, when nested among other case studies that isolate similar programmes in other countries, and investigate common causal processes, is beyond dispute. Most of the time, however, case studies (or other small-n comparisons) are undertaken with only loose attention to comparability with other studies. So case studies often just accumulate. Attempts to compare ﬁndings from such studies exacerbate a classical data problem in social science. Tests of social theories are usually based on data collected for purposes other than testing social theories; theory evaluation with ‘data’ comprised of a hodgepodge of accumulated case studies further compounds the problem.2 More qualitatively oriented researchers do have a point when suggesting that their work can avoid a fundamental social science data problem: it can derive and collect the appropriate data to test a theory. Because analytical comparisons (particularly quantitative comparisons) must assume that their data constitute the correct measurements of the underlying phenomena they are evaluating, ‘qualitative research’ is essential to the comparative evaluation of theories. Anyone with doubts about how critical correct measurement of concepts is for statistical inference should review contemporary texts in econometrics (e.g. Gujarati, 2003). So there are really two problems in comparison. One is using invalid conceptual measures, the second is ensuring that you have consistent measurement across units. Tackling these two problems is important in developing a ‘large-n’ data set to study any question. In many comparisons, this probably does require a set of heavily structured ‘case studies’, demanding detailed knowledge about speciﬁc features of individual units. But this has to be undertaken systematically in order to maximize comparability across the cases. Such work is surprisingly rare in social policy research. Even for topics like comparing national incomes or price levels – big topics with big budgets – there are surprisingly few. In social policy (and many other questions in comparative politics) there are precious few data sets that really attempt to do this in order to answer research questions. The importance of time when comparing welfare state reforms is also obvious, yet absent from much social policy work. Identifying a reform requires at least two time points. Korpi’s (1989) discussion of social rights and welfare development, for example, is quite explicit in its call for considering welfare state developments in time. And, as historically oriented researchers often point out, theories of macrosocial phenomena imply a lot of historical inertia with change in the presence of much noise. But precisely because there is so much noise in historical processes, social scientists

136

State generosity, social rights and obligations

must look at many similar histories in order to be able to verify empirical regularities. The data demanded to evaluate historical path dependence expand exponentially if we want to have much conﬁdence in any claim (de Marchi, 2006: 49–53). History makes information across both time and space (lots of it) vital. Comparative Social Spending The preceding discussion is perhaps too abstract. Knowing that information across time and space is essential to understanding reform tells us nothing about the content. There are, after all, a few widely used crosssectional time series indicators of welfare states available, and they are widely used in the literature. Why are they inadequate? Why is a measure of welfare programme generosity or social rights necessary? The most widely used series of data on welfare reform are probably national time series of social spending. Probably the most popular measures are general government spending, transfer spending and consumption spending (Garrett and Mitchell, 2001). Such measures of spending enjoy a long history in the comparative analysis of social policy and political economy (Wilensky and Lebeaux, 1958; Wilensky, 1975; Cameron, 1978; Korpi, 1983; Garrett, 1998; Swank, 2002b). More recently, the OECD’s social expenditure database represents a comprehensive eﬀort to make comparable speciﬁc categories of social spending (Castles, 2002; Lindert, 2004; cf. De Deken and Kittel, Chapter 5, this volume).3 While it is true that reliance on this spending data is prominent in statistical analyses, many qualitative accounts also utilize a great deal of spending based quantitative information. Undoubtedly, researchers rely on spending measures because they are available, (relatively) comparable, and vary across countries and time.4 Yet researchers widely acknowledge that spending data have signiﬁcant drawbacks, in particular in evaluating welfare retrenchment (Gilbert and Moon, 1988; Esping-Andersen, 1990; Castles and Mitchell, 1993; Clayton and Pontusson, 1998; Goodin et al., 1999). As a guide to understanding the impact of the welfare state on individual life-chances, for example, total spending reveals little about who beneﬁts. As Esping-Andersen (1990: 21) famously remarked, ‘it is diﬃcult to imagine that anyone struggled for spending per se.’ Several other shortcomings of spending data are also worth considering. Welfare Dependency Structure Spending measures do not typically account for the size of the dependent population (but see the contribution of Kangas and Palme, Chapter 6 of

Welfare state generosity across space and time

137

this volume). This is a problem in cross-national comparisons as well as in historical accounts of welfare state commitments. To take the example cited by Esping-Andersen (1990: 20), expenditures on unemployment beneﬁts in the United Kingdom grew sharply in the 1980s under Thatcher, while replacement rates were sharply cut. Rising expenditure was a product of unemployment rising faster than spending cuts. The old-age ratio is perhaps even more relevant in terms of overall social spending. Every OECD country, except Ireland, experienced considerable growth in the over 65 to working-age ratio in recent years. Faster growth in the age ratio implies higher aggregate spending growth and lower aggregate GDP growth, ceteris paribus. Indeed, those studies that have adjusted spending for some indicator of the dependent population are less sanguine about the future generosity of the welfare state; though they often remain sanguine about its overall size (Clayton and Pontusson, 1998, Siegel, 2002; Castles, 2004; Lindert, 2004). Diﬀerent Rates and Sources of Economic Growth and Tax Structures Another problem with most spending ratio data is that diﬀerences in economic growth rates lead spending ratios (spending/GDP) to diverge from real spending itself. Public spending ratios thus underestimate or overestimate inﬂation adjusted welfare expansion. This eﬀect may be biased towards lowering spending ratios in less developed countries (Abramowitz, 1984). Diﬀerences in the tax treatment of transfers (either due to special credits and exemptions, or simply to diﬀerent tax rates) can distort the degree to which spending ratios translate into diﬀerent real levels of state commitment to welfare. The role of taxation as an avenue for social transfers has been given more attention in recent years, but while the tax system is increasingly being used as a transfer mechanism – the United States’ Earned Income Tax Credit and the United Kingdom’s Working Families Tax Credit being notable examples – it can also be used to claw back social spending (Howard, 1997). Adema and Ladaique (2005) discuss extensively how gross expenditure can be oﬀset considerably by the tax treatment of transfers (e.g. making beneﬁts taxable), or by increasing consumption taxes. Ireland and Sweden Compared Based on various spending ratios, Ireland has experienced much greater welfare retrenchment after 1980 than has Sweden. The total spending/ social expenditure ratio between 1980 and 2002 in Ireland fell from 47/17

138

State generosity, social rights and obligations

per cent of GDP to 29/14 per cent. In Sweden the total spending ratio fell from 58 to 53 per cent of GDP, and the ﬁgure for social expenditure was stable at around 29 per cent of GDP. Important changes in demographics, economic performance, and tax structure suggest just how distorted spending data may be as an indicator of generosity. First, in Ireland the dependency ratio dropped dramatically, while it increased dramatically in Sweden. The share of the Irish population over 65 was unchanged over the period 1980–2002 (at 11 per cent), while it grew slightly in Sweden (from 16 to 17 per cent). The share of under 15s in the population, moreover, declined from around 30 per cent to around 20 per cent in Ireland, and was largely unchanged in Sweden (around 19 per cent). Meanwhile, the employment rates of the two countries converged dramatically. In Ireland, non-employment as a share of the 15-64 population decreased from around 43 per cent to 34 per cent between the early 1980s and 2002, while in Sweden it increased from 21 per cent to 27 per cent. Thus, just adding these percentages together (admittedly a very rough gauge), Ireland went from experiencing an 84 per cent (!) non-employment rate in 1980 to 65 per cent non-employed in 2002, while in Sweden this proportion rose from 56 per cent to 63 per cent. So, for a constant share of GDP per non-employed person (again a crude indicator), we would expect the Irish spending ratio to fall by about one-third, while we would expect the Swedish ratio to rise by around 12 per cent. What we observe is a 38 per cent drop in total spending in Ireland (18 per cent social) and an 8 per cent drop in total (nil social) spending in Sweden. Second, the diﬀerence in economic performance between the two countries during this period is also very large. The Irish economy grew at a real rate of 5 per cent per year in this period, while the Swedish economy grew at around 2 per cent per year. This partly follows from the demographic and employment trends cited above – a rising share of engaged labour should increase the economic growth rate – but growth has its own implications for what one might call ﬁscal capabilities. Compared to 1980, real public spending in Ireland was about 180 per cent higher in 2002, while it was just 140 per cent higher over the same period in Sweden. Hence, real spending actually grew twice as fast in Ireland, but since the economy grew about 2.5 times faster, the spending ratio declined. Finally, the evolution of the tax burden on welfare beneﬁts diﬀers somewhat across the two regimes. Eﬀective income tax rates and VAT rates are lower in Ireland, and those rates have declined since 1980 on lower earners (which is assumed to include beneﬁt recipients). In Sweden, income tax rates on earners have also declined, though the overall system is somewhat less progressive than in the early 1980s. While VAT was reduced from 25 per cent to 21 per cent in Ireland, it has increased slightly (from 23.5 per cent

to 25 per cent) in Sweden. Reduced or zero VAT rates apply to many more necessities (e.g. food, social housing, utilities, public transit) in Ireland than Sweden (European Commission, 2005b). Adema and Ladaique’s (2005) analysis seems to suggest that net spending in Sweden is considerably lower than gross spending due to tax clawbacks, while there are fewer clawbacks in Ireland. The point of this example is not to suggest that Ireland has or will become a more generous welfare state than Sweden. It is worth noting that the gap between gross and net public transfer spending in the two countries has closed, particularly in Ireland, which may suggest some reduced generosity. These facts do suggest, however, that very large biases may be hidden in an indicator that is so often implicitly accepted as synonymous with the generosity of the welfare state. From Welfare Spending to Welfare Rights An alternative way to evaluate welfare commitments is an entitlement, or social rights, approach. This is essentially the approach advocated by Korpi (1989), promoted in Esping-Andersen’s Three Worlds of Welfare Capitalism, and which has been widely embraced in comparative social policy (Hicks, 1999; Kitschelt, 2001; Castles, 2002; Green-Pedersen and Haverland, 2002; Armingeon and Griger, 2006; Kenworthy, 2007). The approach is critical of spending as too unidimensional. However, it is still compatible with systematic data collection on more qualitative dimensions of welfare policies. The essence of the rights or entitlements approach is its consideration of the generosity and universalism of social insurance. One can think of social insurance as a political commitment which alters the balance of power between segments of the population or economic classes. Such commitments have behavioural eﬀects that extend beyond government outlays at any point in time. This is an important reason for presuming that spending captures only a small part of how welfare policy structures political outcomes. Welfare state generosity could thus be considered more important than spending when trying to understand the political economy of the welfare state. Viewing social insurance as a commitment is also useful for understanding more traditional questions in the sociology and economics of labour markets. Generosity of welfare commitments may aﬀect things like quit rates, unemployment duration, labour market matching, and other micro-level phenomena that the level of spending will not. There are various sources of data which systematically compare welfare state commitments at some level. However, all contain some important shortcomings compared with the approach in CWED. First, the OECD has

140

State generosity, social rights and obligations

collected data on unemployment beneﬁt programmes, starting with its Jobs Study in the mid 1990s (OECD, 1994). One of its data sets contains estimates of unemployment insurance replacement rates for a typical worker under a variety of scenarios. These data have been used in a number of large-n empirical studies of welfare retrenchment (e.g. Huber and Stephens, 2001). A major shortcoming of this data set is that the replacement rates ignore income and social security taxes, which considerably distorts comparative generosity. This data set also does not take into account important features of beneﬁts, like population coverage or the qualifying conditions. More recently, the OECD has compiled net-of-tax replacement rate data, but these are available only for the mid to late 1990s onwards (OECD, 2005b). These data are also limited to unemployment insurance only, and thus provide a limited, albeit economically important, perspective on welfare insurance programmes.5 Other sources of replacement rate data are scattered in terms of countries and coverage. Hansen’s Elements of Social Security (2002) includes other programmes (e.g. work injury) and income proﬁles, but only covers a few countries and only since the early to mid 1990s. The Nordic Social Statistical Committee publishes Social Protection in the Nordic Countries but this only covers relatively recent years, and only for the Nordic countries. A comparative study of old-age pension replacement rates was provided for the late 1980s by the European Commission (1993). Bambra (2005) also produces an index of ‘decommodiﬁcation’, circa 1998, that incorporates recent data on replacement rates and qualifying conditions plus health data. Finally, SOFI’s Social Citizenship Indicators Project covers the same programmes as CWED, plus work injury programmes. It is more historical, going back to the 1930s, but contains data only for every ﬁfth year. Most importantly, however the data are not available to the scholarly community, despite the fact that they have been in existence for more than two decades. The Comparative Welfare Entitlements Dataset, in contrast to these, contains annual information on replacement rates for unemployment, sickness and public pensions, as well as other eligibility criteria and the size of the insured population. (Plans for the future are to extend the data to cover child care and maternity beneﬁts.) It currently covers 18 countries: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Sweden, Switzerland, the United Kingdom, and the United States, from around 1970 to 2002. Additional information for most countries is available for the 1960s, except for net replacement rates. The data are collected annually, although some extrapolations from bi-annual data have been made where annual data are not present.6 Table 7.1 provides a more speciﬁc breakdown of the particular characteristics in the data set that are used in the rest of the chapter.

The indicators included in the data set are combined to form indices following an aggregation procedure discussed later in the chapter. Conceptually, the measure is very similar to Esping-Andersen’s decommodiﬁcation index, but also contains some important modiﬁcations to the scoring which are detailed below.7

MEASURING WELFARE STATE GENEROSITY This section outlines the basic approach to measuring generosity in CWED by discussing speciﬁc elements outlined in Table 7.1. Programme replacement rates One of the most popular institutional indicators of the generosity of programme beneﬁts is the income replacement rate, that is, the portion of income replaced by a social welfare programme (Esping-Andersen, 1990; cf. Whiteford, 1995; Korpi and Palme, 2003; Allan and Scruggs, 2004; OECD, 2004). Replacement rates provide some measure of the level of well being that is compensated by income transfer programmes. CWED deﬁnes replacement rates as (Cash BeneﬁtsIncome Taxes)out of work/(WagesIncome Taxes)in work where income taxes include net social charges (compulsory contributions to social insurance programmes less cash transfers), and APW refers to the ‘average production worker’.8 Since most working people in OECD countries live in families, CWED provides beneﬁt replacement rates for a single worker and for a family, the latter deﬁned as a household with a dependent spouse, two children and a head of household drawing the speciﬁed beneﬁt. Beneﬁts for families include child beneﬁts, including means tested beneﬁts. Unemployment replacement rates Table 7.2 shows the development of replacement rates for unemployment beneﬁts. The family types are (a) a fully insured single APW wage and (b) a fully insured head of household as described above. The worker receiving the beneﬁt is assumed to be 40 years old, with 20 years of social insurance contributions. The table organizes countries based on (more or less) their traditional classiﬁcation into Esping-Andersen’s Three Worlds typology (cf. Scruggs and Allan, 2006a). In the 1970s and into the 1980s, there is a great deal of diversity across countries, not only for the level of the replacement rates, but also with respect to long-term trends. After the 1980s, replacement rates tend to be stable or decline as a share of APW wages. It is notable that the traditional Three Worlds perspective is not a great predictor of replacement rates (see Hu et al., 2006). There is considerable variation within regime types (calling into question the idea of regimes).

For the single-worker replacement rate, trends for the conservative and social-democratic welfare states converge, while both diverge from the liberal regime average.9 For family replacement rates, there is convergence among all three regimes, with considerable declines in the social-democratic countries in recent years, small declines in the liberal countries, and an increase in income replacement in the conservative countries (mostly due to Italy). Sick pay replacement rates Table 7.3 shows trends in sick pay replacement rates for singles and families which correspond to those provided in the previous paragraph.10 A number of countries, especially among the socialdemocratic and liberal welfare regimes, have sickness replacement rates similar to those for the unemployed. However, it is generally true that the liberal welfare states tend to have lower sickness replacement rates than the

other countries, particularly if we count Japan, as Scruggs and Allan (2006a) and Bambra (2005) suggest, as a liberal country. While the majority of other countries have higher replacement rates for sick pay (e.g. Austria, Belgium, Finland, Germany, Italy, Norway, Sweden and Switzerland), a few have higher unemployment replacement rates. Over time, trends are also similar to trends for unemployment replacement rates. There are a few cases where beneﬁts increased in the 1970s (Canada, Norway, Ireland, Finland), but since the mid to late 1980s, declining replacement rates dominate. Not surprisingly, patterns for family replacement rates also resemble what we saw for unemployment. Preferential beneﬁts for male breadwinner households are no more predominant in conservative welfare states than they are in the countries in the other two regime types.

Social pension replacement rates Table 7.4 shows trends in the replacement rates for social pensions. Social pensions here are deﬁned as the pension beneﬁts for someone without a work history. Where there is not an explicit minimum-age pension, we substitute social assistance. We assume that a ‘family’ consists of two people of retirement age with no children at home. The results indicate that social-democratic regimes have generally provided the most generous social pensions. However, the generosity of these beneﬁts has fallen considerably since the 1980s in Finland and Sweden, and, to a lesser extent, in Denmark and the Netherlands. (Norway is the exception: beneﬁts went up in the late 1990s.) In the early 2000s, Canadian and New Zealand’s social pensions replace as large a percentage of work income as do the social pensions in four of ﬁve social-democratic countries.

Welfare state generosity across space and time

147

Among the conservative regimes, replacement rates do not uniformly support the idea of strictly income linked beneﬁts. While social pensions are low in some countries (Germany, Italy and Belgium), they are among the highest in others (Austria and France, particularly in recent years). Except for Germany, replacement rates have tended to either remain stable or increase. Replacement rates in countries which belong to the liberal regime are also not uniformly low. As mentioned, Canada and New Zealand have comparatively high replacement rates for those relying solely on public pensions. Diﬀerences between single’s and couple’s rates are large in most social democratic countries, as well as in Canada, France and the Antipodes. Across regime types, there is convergence in replacement rates. Beneﬁts in conservative and liberal countries have tended to rise toward the socialdemocratic countries. Replacement rates in social-democratic countries have declined since the 1980s. Standard pension replacement rates The last set of replacement rates presented is for standard public pensions (Table 7.5). These beneﬁts are typically based on a long history of earnings, and are computed using rules governing the treatment of past wages, accrual rates, and calculation formulas. We make a common set of assumptions about career earnings. The basic assumptions are that the notional worker retired on 1 April of the year in question, worked a full career (or from age 21 to retirement age), and earned the APW in each year.11 Family beneﬁts refer to a retired couple with one lifetime APW wage beneﬁciary and a spouse with no work history. Replacement rates and conditions refer only to public pensions, which excludes some pension beneﬁts that are based on sectoral or industrial relations agreements. (For example, supplementary pension regimes in France are excluded.) With a few exceptions, such as the United States, Italy, and Norway, public pension systems fully matured in the 1980s. Since then, replacement rates have either declined or levelled oﬀ. Conservative countries are typically the most generous. Liberal countries have converged only slightly up toward social-democratic countries. This is due to Japan and Switzerland, which both start the period with very small, public pensions. In the social-democratic regimes, there was general replacement rate growth in Norway and Finland, and some expansion of couple’s pensions, speciﬁcally in the Netherlands. In these countries we can observe that ﬁrst retirees who have paid the expected number of years into second pension pillars have started to be rewarded by higher replacement ratios in the more recent past. Across the three regimes, standard pension replacement rates for singles have not converged much over time. The picture with respect to couples,

however, is diﬀerent. There has been considerable convergence. This can be explained by the absence of dependant’s supplements in conservative countries, and an increase in such supplements in liberal and social-democratic countries. Despite its liberal welfare state label, the US Social Security programme is a curious blend of non-liberal attributes. APW replacement rates compare favourably with other countries, the beneﬁt formula is very progressive (those with lower lifetime earnings receive larger replacement rates), and the supplement for a non-insured spouse is 50 per cent of the breadwinner’s pension. (This supplement is much larger than the supplement in any other country.) The main shortcoming of Social Security is that pensions in force have always been indexed to prices rather than wages, something that many pension reforms are moving increasingly towards. The progressive

149

replacement rate formula and earnings ceiling combine to provide a relatively low maximum (compared with many continental systems), which is consistent with company schemes for middle and upper-income households. Across these four programmes and two household types, there are some obvious patterns. First, there is considerable convergence in replacement rates for single-earner families. In general, beneﬁts have converged upwards over the entire period since the 1970s, but with clear evidence of cuts after the mid to late 1980s, particularly in previously high-beneﬁt systems. Whether programmatic cuts constitute true retrenchment is, of course, partly dependent on the deﬁnition of retrenchment and the historical time scale used. For example, virtually all programme replacement rates were more generous in 2002 than they were in the early 1970s in terms of expected worker pay. In terms of real purchasing power (adjusted for inﬂation), they are even more generous. Finally, the results consistently suggest little evidence for the conventional wisdom that social insurance is much more ‘family friendly’ in conservative, continental European countries. Social Insurance Coverage Coverage is considered an important indication of the universalization of beneﬁt eligibility, something that Korpi (1989) argues characterizes mature welfare states. In their seminal article on the development of welfare states, Flora and Alber (1982) included the portion of workers covered by social insurance (see also Flora, 1987b). This subsection discusses coverage trends for unemployment and sickness schemes, and the portion of the population above retirement age in receipt of a public pension. The available data for many countries go back to 1960, so we can assess longer trends than we could when discussing replacement rates. Generally speaking, the results suggest that coverage increased substantially in the 1960s and 1970s, and has not declined since then (with the exception of two aberrant cases). Unemployment and sickness insurance coverage Table 7.6 provides trends in the coverage of unemployment and sickness insurance as a portion of the labour force in 1960 and 2000, as well as changes by decade. A few important notes about these data are worth mentioning. First, coverage for the Antipodean countries is listed as 100 per cent here even though these beneﬁts are means tested and subject to a residency requirement.12 Second, coverage in some countries with Ghent unemployment insurance systems (Denmark, Finland, and Sweden) is based on enrolment in union unemployment funds, even though these are not technically

compulsory insurance systems. Third, the measure of ‘coverage’ in the population used here is often higher than the portion of the unemployed receiving beneﬁts. While it does reﬂect the degree of universalism, it can be criticized for being insensitive to the fact that being in unemployment is not a random draw from the covered population, and those in unemployment may have exhausted insurance beneﬁts or failed to qualify due to incomplete contribution records. Unemployment insurance coverage increased considerably during the 1960s and early 1970s in most countries, and has gradually converged towards full coverage over time. This can be seen in the rising average coverage rates and falling coeﬃcients of variation (standard deviation/mean) in the table. The extension of coverage was typically the result of major legislative changes. Coverage in a number of conservative regimes tended to stagnate after the 1970s. Coverage for sickness cash beneﬁts resembles unemployment insurance coverage in the liberal countries (recall that the two systems have the same or similarly structured replacement rates), except for the United States.13 In the non-liberal countries, coverage is generally higher, sometimes much higher, than unemployment insurance coverage. Finland instituted sickness insurance only in the 1960s, and Canada did so only in 1971. Switzerland and Belgium both saw considerable declines in coverage in the 1990s. The reason for the decline in coverage in Belgium is not clear. In Switzerland, excluding sickness coverage in health insurance policies became easier, and coverage rates (oﬃcial ones at least) declined considerably. Pension take-up rates Unlike coverage of sickness or unemployment insurance, the indicator of the universalism of the pension system is the portion of people above retirement age drawing a public pension.14 Surprisingly, estimating the portion of those over retirement age who are in receipt of a pension presents considerable challenges in many countries. Most countries report the number of pensions paid in their statistical yearbooks. However, many countries have more than one large public pension scheme, and statistics are often compiled for the number of pensions being paid, not the number of people getting pensions. This problem is considerable in conservative regimes such as Italy and France (and even Germany) which have multiple sectoral pension funds. A second complication in determining pension take-up rates is that some countries have administratively separate pension systems for civil servants. The number of civil servant pensions is published for most of these countries, but civil servants are often allowed to retire early and may be entitled to other public pensions (through diﬀerent jobs), making it diﬃcult to consistently avoid under- or over-counts. For example, in the United States, federal employees hired since 1984 have been insured in

the Social Security system, and many (but still not all) state and local government pension systems have also been integrated into the national Social Security system. The ﬁnal complication involves the treatment of spouses. Where second earners have had suﬃcient labour force participation, they will receive a public pension like any other worker. Where spouses have not worked, they would presumably be entitled to a social pension save for the fact that their household pension income (i.e. from their spouse) is higher than the income test. Alternatively, they may be (indirect) beneﬁciaries of a pension supplement in the name of their spouse. These complications should generate some caution at the margins when interpreting the results in Table 7.7. We attempted to compile total pensioner information that includes as much information as possible and avoids double counting. In some cases, we rely on information from public surveys that ask about sources of income. Our results suggest that most of the countries considered here attained something approaching universal take-up, once social pensions, public pensions and civil service pensions are all considered. With a couple of exceptions – e.g. Australia moved towards and then away from making its state pension universal – pensions

are more universal today than they were 30 or 40 years ago. Most of the coverage expansion occurred prior to 1980. Other Eligibility Conditions Here, brieﬂy, I present and introduce the deﬁnitions of the other main conditions of eligibility for social insurance included in CWED. Duration of beneﬁts for sickness and unemployment refers to the number of weeks for which a qualiﬁed worker is allowed to collect regular beneﬁts. In some countries, the duration of beneﬁt is a function of the length of insurance coverage and age. The period given in the data refers to beneﬁts available to the ‘notional worker’: age 40, and 20 years of insurance. There are a few cases where the unemployed are entitled to smaller beneﬁts after the full beneﬁt period (e.g. France). Coding refers to the full duration, including the ‘reduced beneﬁt’ period. Qualifying conditions for unemployment and sickness beneﬁts refer to the number of weeks one must be insured to qualify for cash beneﬁts of the speciﬁed duration. In some cases, this qualifying period is longer than the minimum insurance period required to receive some beneﬁt.15 Waiting days refers to the number of weekdays after becoming unemployed/sick that one must wait for speciﬁed beneﬁts. Thus, for example, it counts the waiting period for earnings related beneﬁts in the UK in the 1970s, even though the (much smaller) ﬂat rate portion of the beneﬁt was payable earlier. The qualifying conditions for pension beneﬁts are based on a slightly diﬀerent set of criteria than those for unemployment and sickness. First, the qualifying period refers to the number of years of insurance necessary to qualify for the standard pension. This is coded to be consistent with the maximum number of years of actual contributions (assuming a full working life and the age of the public pension scheme), since pension replacement rates are based on what one actually receives based on the programme rules. An example may be helpful. A pension system pays 2 per cent of ﬁnal salary for each year of coverage up to 40 years of coverage. The pension law is passed in 1960, going into eﬀect in 1961. Someone retiring in 1970 would retire with 18 per cent of ﬁnal salary (nine years at 2 per cent per year), and has a qualifying period of nine years. Someone retiring in 1971 has a 20 per cent replacement rate and a qualifying period of ten years. Someone retiring in 2002 would have an 80 per cent replacement rate and a maximum (40-year) qualifying period. If the pension system grandfathered in workers (a common occurrence), it might, for example, guarantee 20 per cent of ﬁnal salary for anyone paying in all years that the

155

programme existed. Applying that rule to the above example, someone retiring in 1970 would have a 20 per cent replacement rate, and a nine-year qualifying period, while someone retiring in 1971 would have 20 per cent replacement rate and a ten-year qualifying period. The ﬁnal eligibility condition is the funding ratio: employee social contribution to the combined employee/employer contribution. If the contribution is borne solely by employees, the funding ratio is 1, if it is borne equally by employees and employers it is 0.5.16

COMPARATIVE INDICES OF WELFARE GENEROSITY A widely used empirical indicator of the generosity of welfare beneﬁts is Esping-Andersen’s (1990) decommodiﬁcation index. It is based on several important characteristics of unemployment, sickness, and pension programmes, including the replacement rate for singles and coverage/take-up ratios discussed in the last two sections of this chapter. The decommodiﬁcation index has been used as an indicator of beneﬁt generosity in numerous empirical studies (Huber et al., 1993; Pampel and Gartner, 1995; Rosenfeld and Birkelund, 1995; Mitchell, 1996; Western, 1996; Messner and Rosenfeld, 1997; Crepaz, 1998; Iversen, 1998; Hicks, 1999; Kenworthy, 1999; Huber and Stephens, 2001; Pampel and Williamson, 2001; Radcliﬀ, 2001; Swank, 2002b). The original index was created by assigning each country a score for each characteristic in Table 7.1 based on the cross-country mean and standard deviation for that characteristic, except for coverage and take-up: ‘1’ if less than a standard deviation from the mean, ‘2’ if within one standard deviation, and ‘3’ if greater than one standard deviation. (The points are reversed for characteristics where a higher score implies a more stringent condition.) For each of the three main social insurance programmes, replacement rate scores are doubled, and the other characteristic scores summed. That total is multiplied by the coverage (take-up) rate. CWED data allow us to compute a decommodiﬁcation score for each year: 1971–2002. For each characteristic, the 18-country mean and standard deviation in 1980 is used as the benchmark against which values for all other country-years are scored. The choice of 1980 as a benchmark is ultimately arbitrary, but since this is the year used in the original index, it is convenient for comparative purposes. The overall index, and the index for each of the three component programmes, are presented in Figure 7.1 (the overall score uses the right-side scale). The ﬁgure suggests remarkable stability over the period with little evidence of retrenchment anywhere except in Switzerland,

Sweden and New Zealand. This stability would seem to back up claims that welfare states have been very resilient to pressures for retrenchment. How do we explain this apparent stability? One explanation is simply that welfare state programmes have, in fact, not changed much. Another is that the system of scoring welfare state characteristics is ﬂawed. The scoring is, in fact, insensitive even to very large changes in the values for underlying characteristics. For example, Belgium’s unemployment replacement rate moved up from 55 per cent to 70 per cent (0.8 standard deviations (sd) spanning the mean) between the early 1970s and mid 1980s. It then falls to around 62 per cent by 2001 (a decline of about 0.4 sd). This would seem like a clear case of expansion and retrenchment over time. However, because the replacement rate never exceeds one standard deviation above or below the cross-country mean in 1980, the scoring procedure from Three Worlds scores it a ‘2’ for all years. A related problem with the scoring procedure is that, in a given year, a country with consistent, but moderately generous, programme values is scored the same as a country with consistently low values. For example, assuming full insurance coverage for the working population, a country that is 0.9 sd for all of four characteristics of sickness insurance would receive a sickness decommodiﬁcation score of 10; this is the same score that a country scoring 0.9 sd from the mean on all characteristics would receive. Meanwhile, two countries scoring only marginally higher/lower – e.g. 1.05 sd from the mean – for all characteristics would receive the maximum/minimum score (15 and 5 respectively). A more appropriate, and perhaps more intuitive, scoring method is to use the standardized values for each characteristic (except for coverage). Comparing countries on a continuous scale eliminates most of the problems referred to above. First, it avoids arbitrary assignment of cut-oﬀ points. While one might argue that this artiﬁcially creates a continuum, this is superior to arbitrary assignment of cut-oﬀ points at / one standard deviation, and prevents any accidental bias in the creation of cutpoints (see Scruggs and Allan, 2006a, b). The revision scores a country that is ‘moderately high’ on many characteristics higher than one that is moderately low on all, while countries that are ‘a bit high’ on some and ‘a bit low’ on others score like those with a programme that is in the middle on all attributes. The upper and lower bounds of the scores are also truncated to be / 2 in order to prevent an outlying score from distorting the overall distribution of results. Furthermore, in order to make all scores positive, we add 2 to each characteristic score so it varies between 0 and 4 rather than 2 and 2. The ﬁnal major change to the decommodiﬁcation scoring is the use of replacement rates for the family household type. This is justiﬁed largely on the basis that the vast majority of workers are members of families, not

single workers. To make the relative weights of replacement rate scores similar to those in the decommodiﬁcation index, the replacement rate scores for singles and couples are no longer weighted twice. It is not clear whether Three Worlds relied only on single-worker replacement rates because the family rates were not available in the SCIP data at the time, or due to a fear that generous spousal supplements in ‘conservative’ welfare systems in continental Europe would conﬂate state support for traditional family structures with decommodiﬁcation. In the latter case, there are two problems. First, it is not clear that support for traditional families does not in fact constitute decommodiﬁcation, albeit not the postfeminist social-democratic one. Second, based on the replacement rate data in the previous Tables 7.2–7.5, there is really no evidence that conservative regimes have higher family replacement rates due to family supplements. The revised decommodiﬁcation scores, which we label the beneﬁt ‘generosity index’, are plotted with scores computed using the original methodology (right-axis scale), and as presented in Figure 7.2. Table 7.8 shows the generosity index scores in 1980 alongside Esping-Andersen’s decommodiﬁcation data in order to provide a direct comparison between

the CWED results and the original decommodiﬁcation index from the Three Worlds of Welfare Capitalism. Table 7.8 suggests, unsurprisingly, some basic correspondence with the original decommodiﬁcation index. First, three paradigmatic cases – Germany, Sweden, and the United States – all ﬁt squarely with the Three Worlds ranking. A number of other cases also ﬁt: Australia, Austria, France, and the other Scandinavian countries. Several anomalies in the original text – Switzerland and Finland – also appear anomalous in our ranking. On the other hand, Japan and Italy emerge in our rankings as extremely liberal countries, with low decommodiﬁcation scores, while New Zealand appears much more decommodifying than suggested by the decommodiﬁcation index. The Netherlands’ score is also much closer to those in the Scandinavian countries in the generosity index than it is to scores among the conservative regimes like those of France and Germany. Finally, the overall variation among countries, particularly the distance between the best and worst, is much less in the generosity index than the decommodiﬁcation index. Such an exaggerated variance between liberal and social-democratic countries suggests that existing empirical relationships employing decommodiﬁcation as an explanatory variable, or as a variable thought to determine decommodiﬁcation, are overstated. Are these diﬀerences very signiﬁcant substantively? Consider that the original decommodiﬁcation index suggested anomalous results for two of the 18 cases – Switzerland and Finland. Our results suggest anomalous results for at least four additional countries – Japan, Italy, the Netherlands and New Zealand. Since our approach replicates the same underlying data that were used in Three Worlds, the results are not a case of employing diﬀerent indicators. Presumably, our results should be almost identical. This implies a much more tenuous ﬁt between theory and reality than comparative social policy scholars have been led to believe. Compared with the original scoring method, our revised measures show a much greater degree of variation within many countries over time. Figure 7.2 suggests that the 1970s were an important period of increased beneﬁt generosity in many countries, that the 1980s saw somewhat more expansion in generosity, and that the 1990s were a period of reduced generosity. All of the social-democratic regimes, except for oil-fed Norway, were considerably less generous in 2002 than they were in the mid 1980s. Germany, France, and, to a lesser extent, Belgium, also appeared to be substantially less generous in 2002 than they were in the mid 1980s. This contrasts with spending ﬁgures; which were higher in 2002 in all three countries. The trends also indicate that a number of countries were less generous in 2002 than at any other time in the last generation. Indeed, Germany, despite its reputation as a welfare reform laggard, is probably the only country that has been consistently less generous

over the period covered (see Siegel, 2004 for corroborating evidence). Explanations of this greater within-country variation should be of intrinsic interest to researchers. One immediate implication for the comparative social policy ﬁeld is that one should be careful in assuming that cross-sectional variations at a single point in time are valid much earlier or later in time. Unfortunately, a great deal of work since Three Worlds has tended to do that. Figure 7.3 provides the average annual scores for all countries and annual averages in each welfare regime (which we have deﬁned here according to the conventional classiﬁcation, not the one implied by our results in Table 7.8). It mirrors patterns described in earlier sections of the chapter. By the early 21st century, generosity is higher than it was in the 1970s. Programme generosity tends to increase until the mid to late 1980s, after which there are some clear signs of retrenchment. This is especially true in the more generous social democracies. Finally, after diverging throughout the 1980s, scores seem to converge through 2002.

CONCLUSION: WHY AND HOW TO IMPROVE THE CONCEPTUALIZATION AND MEASUREMENT OF WELFARE STATE PERFORMANCE The CWED project data set is far from a complete or ideal set of data on welfare programme commitments. What the project has attempted, and

162

State generosity, social rights and obligations

what should be repeated in all future empirical research on comparative welfare states, is to expand the scope of comparison by trying to measure things in a systematic way across as many countries and years as possible. Here we make several speciﬁc suggestions that can further improve the depth, quality, and comparability of social rights and welfare state institutions across countries and time. First, social entitlements need to consider two-earner households and single-parent households. Two-earner households have become the norm in most countries, and single-parent households are a particularly vulnerable group in all countries. We have a very patchy view of how the tax and beneﬁt systems have interacted to aﬀect such groups over time. In addressing this issue, there are several complications that have to be confronted. The experience with the CWED suggests that computing replacement rates and beneﬁt conditions for these alternative households will be a considerable task, but that it can be accomplished more easily if it builds on the current project. Second, the distributional eﬀects of welfare programmes across income and social strata are not well examined. The generosity measure is computed for a single point in the wage distribution (the average production worker). However, two policies aﬀecting a typical worker in the same way may aﬀect lower (or higher) earners diﬀerently.17 Are cuts aﬀecting some income groups and not others? Are those aﬀected actually groups that should be targeted for cuts? Third, there is still a paucity of systematic comparative data on alternative types of social rights. Indeed, virtually none of the literature considers the adequacy of social assistance, arguably the ultimate social ﬂoor of the welfare state. Other substantive improvement in data might stress the role of non-cash beneﬁts and services. Still other improvements would take up programmes that provide a more balanced gender orientation to welfare state programmes, such as assistance programmes targeted at single parents. While most of the above criticisms are not new, work on the next step – specifying new conceptions and associated observables – tends to lag. There is, for example, little work comparing social assistance programmes in the context of social rights and income replacement (Gough et al., 1997 is an exception, but even it primarily looks at spending levels). ‘Universal services’ are often casually asserted as aﬀecting outcomes, but a systematic comparative evaluation of the distributive implications of such services is needed to include them in the analysis alongside cash beneﬁts. Finally, and apropos of the three previous suggestions, we simply need more data across space and time using the main concepts that we already focus on in the literature. Too often, interesting contemporaneous indicators

163

are developed to investigate (or deﬁne) some ‘new or ‘nationally unique’ social problems. Appellations such as ‘new’ and ‘unique’ imply comparison to other things, yet those comparisons tend to stop at the preliminary stages, just when the necessary work to be done is identiﬁed. The importance of establishing appropriate measures of generosity is vital. Social scientists tend to focus overwhelmingly on creating ‘new theory’ (or modifying old theories). Developing tests of theories is typically an afterthought, or worse, ‘test development’ becomes an exercise in a search for measures to show that this is consistent with a theory. Why it is so would ﬁll its own volume (or, on second thoughts, may be all too obvious) but it is scientiﬁcally pathological. If concepts in a theoretical model are poorly operationalized and measured, then we are not testing the theoretical model. One might argue that social science contains very abstract, hard to operationalize concepts and theories, so asking for precise correspondence (compared with, say, physics) is unreasonable. This has it completely backwards. Errors probably proliferate exponentially: sloppily operationalizing sloppily theorized relationships does not make a ‘good test’. The time spent conceptualizing and operationalizing should vary inversely with theoretical speciﬁcity (allowing of course for some minimal standard of both). Vague theories demand more attention to concept validity and better measurement, they do not justify worse concept validity and measurement. Mis-measurement produces well known problems in statistical analysis, including bias and inconsistency of parameter estimates (Gujarati, 2003: 526–7). Since many claims about causal relationships are based on inferences drawn from statistical analysis, measurement problems may fundamentally undermine existing ‘facts’. For example, a great deal of recent empirical research relies on spending data to infer that the relationship between political partisanship and welfare state generosity has largely disappeared in the ‘era of permanent austerity’. If, however, as many (perhaps most) social policy scholars suggest, spending data have always been poor indicators of welfare generosity – or if previous non-spending indicators of generosity (e.g. the decommodiﬁcation index) are mis-measured – then empirical results are ‘biased’ against ﬁnding any eﬀects. Indeed, results with non-spending programme data as discussed by Allan and Scruggs (2004) or Korpi and Palme (2003) suggest that partisanship continues to play a big role in explaining variations in welfare state generosity in the era of austerity.18 The emperor has no new clothes. Mis-measurement presents even more serious problems when it occurs on the right-hand side of a regression equation. There it produces not just ineﬃcient but also biased estimates of the eﬀects of generosity as a causal variable. This suggests that the estimated eﬀects of social spending in numerous statistical models throughout comparative political economy

164

State generosity, social rights and obligations

more broadly may provide biased and inconsistent impressions of the actual eﬀects of welfare generosity on a wide variety of social processes. The size and direction of these biases is unknown until those results are corrected with a more accurate operationalization of generosity.

The most obvious shortcoming of current data sets and theory evaluation (including the current one) is that the ‘sample’ remains so selective: less than 20 of the same Western, industrial countries. This tends to make the idea that any new explanation is really ‘tested’ (rather than simply derived from them given how much we already know) quite problematic. There is, furthermore, almost no eﬀort to use results to make any predictions which are evaluated against evidence. If the explanations were very good, for example, then they should help us (a) predict results in other countries, (b) predict future trends in the current countries under study or even (c) ‘postdict’ the past. The problem is more than simply that the social science data are observational; the available data are generally collected for some alternative purpose than testing the theory that the social researcher wants to test. Pierson (1994), to cite one of the most inﬂuential examples, exempliﬁes the practices alluded to here. First, his argument often relies considerably on spending trends to bolster his central argument that there has not really been welfare state retrenchment. Second, the book provides ‘new’ political explanations with a selective consideration of ‘old’ explanations which might predict results with the same success (Scarborough, 2000). Third, and perhaps most problematic, this line of explanation bears no resemblance to a progressive research programme. The ‘new politics’ explanation makes no real eﬀort to explain both past and present under the same model, it asserts that the present requires a diﬀerent one. Kittel and Winner (2005) suggest that this variation is limited, making pooled statistical analysis of these data potentially problematic. The need for cross-sectional, historical data sets exists independently of questions about how to analyse them. One advantage of the OECD indices is that, in recent years, they incorporate housing beneﬁts and social welfare (the latter available after insurance beneﬁts are exhausted) replacement rates. Detailed sources and procedures are available in the data set codebook. Some uses of the SCIP data (e.g. Sjöberg, 2000b) extrapolate between the ﬁve-year interval data points to get ‘annual’ data, or else (e.g. Korpi and Palme, 2003) rely on some other extrapolation procedure to get annualized data. A comparison of our and Esping-Andersen’s results is provided in Scruggs and Allan (2006a). Analyses using the index are Armingeon and Griger (2006), Pontusson (2006), Hu et al. (2006), Scruggs and Allan (2006b), Scruggs (2005). APW wages and taxes used here are provided, with modiﬁcations, by OECD publications like Taxing Wages. We use net beneﬁts payable in the ﬁrst six months of receipt. Further details of the calculation of replacement rates computed in each country and year are provided online in the data set codebook and replacement rate spreadsheets at the CWED website. The current placement of some countries – especially Ireland, Japan, the Netherlands and Japan – is very ambiguous (compare, for example, Esping-Andersen, 1990; Castles and Mitchell, 1993; Esping-Andersen, 1999; Scruggs and Allan, 2006a; Shalev, forthcoming) but not substantively important here. It is important to note that we include periods in which employers are legally obligated to pay wages to absent employees as insurance payments in computing replacement rates. We do so based on the assumption that such payments constitute legal rights.

Using the wage in the year of retirement as the ‘historic insured wage’ leads to a considerable overstatement of actual beneﬁts. Many pension systems were designed to be based on a long earnings history, a fact obscured by comparatively long transitional periods which were especially favourable to transitional workers. This describes inter alia the (pre-reform) Swedish and American systems. Further details of speciﬁc cases are available in the CWED data (also see Scruggs and Allan, 2006a). When we discuss the generosity index, we will assume coverage is 50 per cent to account for the fact that the beneﬁts are purely means tested. The non-zero values for the United States in the table reﬂect the fact that ﬁve states, including California and New York, have sick pay insurance modelled on their unemployment insurance systems. Another important factor to consider in interpreting all of the sickness beneﬁt data is that most (though certainly not all) Americans receive some paid sick leave each year from their employer. Coverage rates for public pensions (the proportion of people in the work force who are insured) are hard to evaluate, because many people not in the labour market at a given time can be entitled to a pension based on their previous work history. Thus, the number of people paying social contributions for pensions in a given year (or counted as entitled to a pension) may be a considerable undercount. Empirically, our coding choice tends to give ‘length of service’ rules comparatively long contribution periods and beneﬁt durations. This seems to be consistent with how such systems are comparatively characterized in the literature. However, this obviously fails to fully capture some diﬀerences in the way the ‘length of service’ features of this insurance model function. Choosing diﬀerently, e.g. taking the minimum qualifying period and duration would also be imperfect and correspond less closely with distinctive features according to social policy scholars. This procedure was adopted to be consistent with Esping-Andersen’s decommodiﬁcation index. The measure has two shortcomings. First, it ignores the general tax system’s role in funding pensions. Second, it assumes a certain ‘paycheque illusion’. Whether a social contribution is paid out of each worker’s salary or is based on a percentage of the employer’s total wage bill makes no real diﬀerence to take-home pay. Some of this type of work has been done (e.g. Hansen, 2002). However, the countries and years of coverage are limited, making it diﬃcult to discuss very broad trends. Because generosity measures, like spending, trend upward during the 1980s they are theoretically and empirically compatible with a role for partisanship in explaining welfare expansion and retrenchment. Unfortunately, the ‘new politics’ literature fails to explain the rise of the welfare state via the same causal processes invoked to explain retrenchment. If new theories only need to explain new events – and not also ‘cover’ new and old events – there is not much recourse to external veriﬁcation or theory builiding: one can safely have a diﬀerent theory of each event. Not an impossible state of aﬀairs, but one which seems to command that we give up the candle of social science.

8. Levels and levers of conditionality: measuring change within welfare states Jochen Clasen and Daniel Clegg INTRODUCTION Bold claims are often made about the current development of welfare states, both by critical theorists of social policies and by the politicians that are reforming them. But characterizing the nature and magnitude of the changes that welfare states have undergone in recent decades seems to pose major problems for empirical – and particularly comparative empirical – analysis. The lively debate concerning the range of factors that may result in (more or less) change in social protection arrangements – including most importantly structural socioeconomic forces, changing power resources, new ideas, party competition, institutions, policy legacies and path dependence (for overviews, see van Kersbergen, 1995; Amenta, 2003) – is complicated by the fact that analysts struggle to agree on what, exactly, is the real character and extent of change to be explained. Controversies and contradictory readings abound in the comparative social policy literature. Have we, as some maintain, witnessed a ‘paradigm shift’ in the techniques and strategies for managing social risks, or merely a series of adjustments at the margins? And if recent reforms are leading to the emergence of a distinctively new ‘type’ or ‘form’ of social policy, is this equally true in all developed welfare states, or only (to date) in some? While in social sciences there is always scope for diﬀering interpretations, convincingly and consistently answering these kinds of questions arguably turns ﬁrst and foremost on the identiﬁcation of the most appropriate data for examination. Diﬀerently put, the key challenge for assessing the extent of certain hypothesized or postulated changes in welfare state programmes is not so much one of accurate measurement, but rather of developing more adequate conceptualizations and operationalizations of the possibly variable qualities of welfare state programmes. Arguments about new forms of social policy provision or regulation speak to certain welfare state properties in 166

particular, and not necessarily those for which comparative indicators are most readily available. Only by focusing on the most salient dimensions of social policies, and developing truly relevant comparative benchmarks, will compelling cross-national assessments of arguments about the direction and implications of ongoing welfare reforms be possible. Without pretending to present a ‘best’ or ‘deﬁnitive’ solution to the inevitably thorny problem of characterizing dynamic patterns of policy provision and regulation in welfare states, this chapter advances one possible analytical framework which, we argue, can usefully complement indicators more habitually used in cross-national comparisons of welfare state arrangements. This framework is based on the analysis of the degree of conditionality that is written into the design of all social programmes. By paying close attention to changes in time across what we call the levels and levers of conditionality, we argue that it is possible to identify the extent and pace of changes in the management of social risks that are implicit in the reforms to welfare state programmes that have been implemented in some – but not all - countries in recent decades. The argument is organized in three sections. In the ﬁrst of these, some of the measures and indicators that are most widely used in cross-national welfare state analysis are discussed to highlight their limitations in capturing the more qualitative shifts that are widely argued to be occurring in the contemporary period of welfare state reform and change. As a possible complement, rather than alternative, the second section then presents our framework for conceptualizing and analysing (changing) patterns of conditionality in beneﬁt provisions. This framework distinguishes notably between three discrete levels of conditionality which we call conditions of category, conditions of circumstance and conditions of conduct, each having distinctive levers in legislative provisions for social security. Drawing on data from four European countries, the third section applies the framework to an analysis of change within unemployment protection since the early 1980s, measuring the extent to which each of the diﬀerent conditionality levers has been loosened or tightened in recent reforms, and examining the patterns across all three levels. We conclude with a brief summary of the merits and limits of the approach.

THE PROBLEM OF CHANGE IN COMPARATIVE WELFARE STATE RESEARCH While much academic debate in recent years has been focused on the extent to which the welfare state has been rolled back – a veritable ‘retrenchment business’, as Hinrichs and Kangas (2003: 574) have called it – other scholars

168

State generosity, social rights and obligations

have been exploring more complex shifts in the proﬁle of social provision. Contemporary welfare state change is not (only) about retrenchment, but (also) about the more structural agendas that terms such as ‘modernization’ and ‘recalibration’ seek to capture (cf. Pierson, 2001). Some have argued that the welfare state is being superseded by an ‘enabling state’ (Gilbert, 2002), while others have spoken of the emergence of a ‘social investment state’ (Esping-Andersen et al., 2002) or an ‘active social state’ (cf. Vielle et al., 2005). These leitmotifs of welfare state change suggest not merely a modiﬁcation in the scope or reach of the welfare state, but instead a structural transformation – or paradigm shift – in ways of managing and regulating social risks. Although they have stimulated a lively normative debate, it has proved more diﬃcult to provide systematic evidence of these leitmotifs inﬂuencing actual social policy reform. For if disagreements and disputes over the most appropriate indicators has been a characteristic of the retrenchment business (see Green-Pedersen, 2004 and Chapter 2 in this volume), the ‘dependent variable problem’ is arguably even more acute when it comes to the comparative analysis of more qualitative and structural changes in social policy. Considering the three main types of indicators that are most widely used in comparative research on social policy and welfare states – social expenditure, social policy institutions and ‘social rights’ – helps to highlight the problem. The ﬁrst of these, social expenditure, is the most traditional measure of comparative social ‘eﬀort’, at either the aggregate (welfare state) level or at the level of particular social risks and individual social programmes. Having been somewhat discredited as an inadequate proxy for the development of social rights in earlier comparative work (cf. infra), the analysis of levels of social expenditure has been revitalized by the retrenchment business, and is today used in increasingly sophisticated statistical analyses of welfare state development (e.g. Kittel and Obinger, 2003). Furthermore, closer attention to the impact and extent of tax breaks, direct and indirect taxation and mandatory private expenditure (e.g. Hacker, 2002; Adema and Ladaique, 2005), on the one hand, and the integration of cross-national variations in risk intensity (e.g. Siegel, 2002 and Chapter 4 of this volume), on the other, has helped to enhance the descriptive accuracy of social expenditure comparisons. It remains the case, however, that even the most sophisticated indicators of overall eﬀort capture only the quantity of investment in collective social protection, are still onedimensional and can say little about the risk management strategies underpinning social interventions on which the leitmotifs of welfare state change often turn. Focusing on the structure rather than the level of social expenditure may oﬀer a potentially more fruitful strategy. As Castles (2002) has pointed out,

169

certain changing priorities of policy makers may well be captured by examining the (appropriately ‘adjusted’ or ‘standardized’) share of expenditures on the diﬀerent social programmes, covering diﬀerent social risks, in disaggregated data sets such as the OECD’s social expenditure database (SOCX, OECD, 2005a). For example, an increasing share of spending on rehabilitation programmes or active labour market policies relative to unemployment or disability beneﬁts could be seen as indicators of a shift to an ‘active welfare state’, and a shift from expenditure on pensions to child care or education proxies for the development of a ‘social investment state’. It is not certain, however, that this kind of macro-level, expenditure based approach is really capable of capturing ongoing changes in a timely fashion. There is potentially quite a long causal and temporal chain between the legislative changes that concretely reﬂect changing public priorities and shifts in the structure of social expenditure (see also Chapter 4 by Siegel, Chapter 5 by De Deken and Kittel, Chapter 6 by Kangas and Palme, this volume). This may explain the fact that although data of this sort suggest that there has been minimal ‘structural change’ in, for example, the German welfare state (Castles, 2002), recent research using more case oriented approaches has arrived at very diﬀerent conclusions (e.g. Bleses and Seeleib-Kaiser, 2004; Clasen, 2005). The second important family of indicators that are increasingly used in comparative welfare state research are derived from broad institutional characteristics of welfare state programmes. For example, following Ferrera (1996), Palier (2002) has suggested that national proﬁles of social policy arrangements can be captured according to the dominant values taken on four institutional variables in social protection: the ﬁnancing system (social contributions, general taxes, co-payments), the management structure (state, social partners, local authorities), the type of beneﬁt (ﬂatrate, earnings related, means tested) and the mode of access to beneﬁts (citizenship based, contribution based or needs tested). Considered at either the whole system or sectoral level, these variables combine to demarcate diﬀerent ‘ways of doing’ social policy in diﬀerent national contexts. For Palier, evidence of signiﬁcant qualitative change in social policy arrangements is accordingly most convincingly highlighted by changes in the values taken – measured according to the appropriate structural indicators – on one or more of these variables. This framework for analysis has proved very useful in capturing some developments in social protection systems, not least because it integrates ‘input’ dimensions of social policies (such as ﬁnancing or management) that were often neglected in previous comparative research. It establishes very demanding conditions for the identiﬁcation of change, however. Thus, a change in the type of beneﬁt deployed to manage a given social risk would

170

State generosity, social rights and obligations

only be identiﬁed on the basis of a shift from, say, a primarily earnings related (social insurance) to a primarily means tested (social assistance) approach. Though of course possible in the longer term, such wholesale ‘regime’ shifts remain rather unlikely in the short term. Furthermore, as Leitner and Lessenich (2003) have argued, the nature and quality of a particular social insurance beneﬁt can vary quite considerably over time according to the setting and resetting of its lower-level institutional parameters. Perhaps more importantly for current purposes, a related risk of the approach is that it seems to reduce possibilities for identifying change to shifts within the standard palette of already existing institutional ways of doing social policy, and may thus fail to capture forms of innovation that introduce entirely novel arrangements. Thus, if Palier’s (2002) suggestion may prove useful in showing that country x is increasingly using a risk management strategy conventionally associated with country y, it would have diﬃculty showing that either country x or country y is groping towards a quite new model of risk management. Because they cannot easily capture either subtle but potentially signiﬁcant shifts within relatively stable macroinstitutional parameters or forms of institutional innovation that touch only marginally on the standard (‘golden age’) variables of welfare state structure, the use of only broad institutional indicators of welfare state quality may lead to an exaggeration of the extent of stability in welfare state programmes. The ﬁnal family of commonly used approaches to comparative social policy mapping and analysis are based on what Siegel (2003) calls ‘social rights’ indicators. Though indicators such as beneﬁt levels and replacement rates also belong in this family, the most sophisticated and probably best known social rights indicator is the measure of ‘decommodiﬁcation’ ﬁrst devised by Esping-Andersen (1990; see also Scruggs in Chapter 7 of this volume). Criticizing expenditure indicators for failing to capture the essence of social policies, and the political struggles that surround them, Esping-Andersen combined information from a range of quantiﬁable micro-institutional parameters of social policies (e.g. replacement rates, contribution conditions, waiting days) to develop a measure of the extent to which welfare states decommodify individuals, that is free them from dependence on the sale of their labour power in the market. He was then able to place countries on decommodiﬁcation scales, again in respect of both particular sectors of social policy and their entire welfare states. Decommodiﬁcation speciﬁcally, and measures of the generosity of social rights more generally, remain crucial benchmarks of the quality of diﬀerent social programmes and welfare states. Moreover, their ability to quite directly tap into the question of social citizenship – the role of the state in furnishing individual opportunities and resources – in many respects gives

171

them a better ‘handle’ on the themes at the centre of more normative discussions about the ‘new welfare state’ than expenditure or broader institutional indicators. That said, however, these indicators are arguably also increasingly wanting. Political discourse within social policy has in recent years been progressively shifting away from rights and towards ‘responsibilities’, and an assessment of the changing ‘social citizenship relationship’ requires attention to both. Although measures such as decommodiﬁcation are ﬂexible enough to incorporate measures of changes in certain responsibilities (or conditions) for beneﬁt receipt, they cannot capture all of these. Most importantly, measures of social rights take the notion of social risks largely as given, while much current political discourse concerns the need to reconceptualize and reorganize the boundaries of risk categories, and to make their collective treatment more individual and less social. Capturing the extent and progress of these themes in actual policies arguably also requires additional indicators (see Scruggs in this volume). To summarize the discussion above, the main kinds of indicators used in comparative welfare state analysis capture diﬀerent dimensions of welfare state variation, and each is valuable for understanding of particular kinds of social policy performance and development. Each, however, also has more or less severe weaknesses as empirical indicators of change in the structure and form of welfare provision and regulation that dominate much of the more normative or critical discussions of contemporary social policy reform dynamics. Though social rights approaches probably operate at the level most apt to analyse the changes in the social citizenship relationship that this literature prescribes, describes or decries, they lack the conceptual focus necessary to empirically capture salient dimensions of this relationship. It is in this context that the analytical framework that we present below can perhaps enhance our capacity to comparatively assess both the scope and the implications of ongoing transformations in the architecture of social programmes.

A CONDITIONALITY APPROACH This framework or approach is centred on the notion of conditionality. Conditionality has been something of a ‘buzzword’ in recent welfare state discourse, and some scholars have even presented ‘conditional aid’ as representing a new paradigm for social policy (cf. Dufour et al., 2003). Our approach to this issue is somewhat diﬀerent. We depart from the observation that, ﬁrstly – and contrary to the impression that is given by some more recent discussions of conditionality – individual rights to social beneﬁts have always and everywhere been conditional in some ways, and conditionality is

172

State generosity, social rights and obligations

as such a cornerstone and basis of risk management in welfare states (cf. also Goodin and Rein, 2001). Secondly, however, there are several dimensions as well as a range of possible ‘levels’ and ‘levers’ of conditionality in social policy, and diﬀering balances between these levels and levers can tell us something potentially important about the pattern of risk management that is institutionalized in and through social policies. Evidence of variation in this balance, therefore, can – thirdly – generate benchmarks for assessing the direction and scope of change in the comparative analysis of welfare reform. It should be emphasized that assessing modiﬁcations in the conditionality underpinning welfare provision is not intended to serve as a substitute for other indicators but as a complementary measure, albeit an important one. As will become apparent, the conditionality of a cash beneﬁt, for example, says nothing about its generosity (which might be measured as a replacement rate) or about the institutional structure through which it is delivered. Nevertheless, a focus on the conditionality of welfare state programmes does help to capture changes in the relationship between rights and responsibilities, and thus provides an empirical basis for gauging the reality of ‘transformations’ in social citizenship often heralded in welfare state literature and debates. For this to be possible, it is ﬁrst necessary for the various ways that conditionality can be adjusted in welfare reforms to be deﬁned and distinguished analytically. Conditions of Category The ﬁrst, or primary, condition for the receipt of social security is always membership of a deﬁned category of support; being past retirement age for retirement pensions, having some form of disability for incapacity beneﬁt, being unemployed for unemployment beneﬁts and so on (Bolderson and Mabbett, 1996). Even so-called universal beneﬁts do not entirely abolish ‘categorical gateways’ to support (cf. Gal, 1997; Goodin, 2000; Kiddal and Kuhnle, 2005); universal health care is of course only available to the sick, and even a basic income ‘for all’ is conﬁned by citizenship or residency conditions. Though risk or membership categories are often taken as given in measures of social rights, it should be remembered that they are in fact socially constructed and politically managed, and thus subject to potential change, either in a more restrictive or more expansive or encompassing direction. An obvious case is pension age, which has been the subject of pressures for (mainly restrictive) reforms in most countries in recent years, and actual reforms in many. But governments have also changed deﬁnitions of risk categories such as unemployment, for example by excluding certain social groups or categories of worker (single parents, older people, students . . .)

173

at certain times and reintegrating them at others. Even where categorical gateways have professional gatekeepers – for example doctors, as in the cases of health care or disability beneﬁt programmes – politicians have often changed directives and guidance they give to these professionals in an attempt to use the lever of category deﬁnition to impact on inﬂows into beneﬁt receipt. Conditions of Circumstance Analytically secondary to conditions of category are conditions of ‘circumstance’ or, in more common social security parlance, eligibility and entitlement criteria. The fact that this type of conditionality has always underpinned welfare state provision is most obvious from the fact that some of their (potentially varying) settings and codiﬁcations have traditionally been integrated in the calculation of synthetic indicators of social rights, such as Esping-Andersen’s decommodiﬁcation index referred to earlier (again, see Scruggs in Chapter 7 of this volume). For social insurance beneﬁts, for example, legislation has long included rules regarding the extent to which and how a claimant’s work history determines access to beneﬁt rights. The pertinent and potentially varying considerations in social security legislation include the number, or value, of contributions and/or full days of labour that are required in a given time period to open access to beneﬁts, as well as the extent to which these contributions must be real (from paid work) or can also be ﬁctitious and credited (i.e. related to non-work activities such as child rearing, home work, education etc.). Accordingly, individual access to a social insurance beneﬁt can be more or less conditional, with the polar extremes of the range sometimes captured in the distinction between ‘Beveridgean’ and ‘Bismarckian’ social insurance, i.e. loosely or tightly conditional on paid employment (cf. Clasen and van Oorschot, 2002). Though it is less often remarked (and far less well integrated in crossnational indicators of social rights), it should be pointed out that means tested (or assistance based) beneﬁts have also always incorporated potentially varying degrees of a structurally similar – though necessarily operationally diﬀerent – form of conditionality. Though still conditions of circumstance, the circumstances in question are not – as with classic social insurance beneﬁts – work histories, but instead the claimants’ degree of ﬁnancial need. But the deﬁnition of need can vary in both extensity (narrow or wide deﬁnition of family obligations to support; many or few types of income and wealth taken into consideration) and in intensity (level of income and wealth disregarded; level of marginal tax applied) (cf. Eardley et al., 1995). Following from this, the risk management in assistance based

174

State generosity, social rights and obligations

beneﬁts can serve either to ‘screen in’ only the poorest and most needy population or to ‘screen out’ only the richest and least needy (Castles and Mitchell, 1992; Mitchell et al., 1994). Indeed, it is only in a ‘pure’ case of universal beneﬁts that we ﬁnd no conditions of individual circumstance whatsoever in the design of social security beneﬁts. In the two other main kinds of social security programme, the various levers of work- or need-related eligibility criteria can be tightened or loosened to make social rights more or less accessible for the individual and thus more or less encompassing for society as whole. For social insurance beneﬁts this can happen independently of changes impacting upon the beneﬁt’s formal generosity (or level of entitlement) as measured through e.g. replacement rates. Conditions of Conduct The third and ﬁnal level of conditionality is for its part logically subsequent to the others, intervening only after eligibility for beneﬁt has been otherwise established, and having the function of regulating the ongoing beneﬁt receipt. It pertains to what could be called conditions of ‘conduct’, with the policy levers being the tightening or loosening of behavioural requirements and constraints imposed upon diﬀerent kinds of beneﬁt recipients through legislation or administrative guidance. This is the form of conditionality that has featured most prominently in recent discussions of the ‘new welfare state’ and the changing nature of risk management and the social citizenship relationship. The most obvious case of a growing emphasis on this tertiary level of conditionality in policy reforms are so-called activation policies for the unemployed, under which unemployment beneﬁt and unemployed social assistance recipients are, for example, obliged to provide evidence of job search activities, participate in training programmes or agree to specialized counselling (cf. Lødemel and Trickey, 2001; Dufour et al., 2003; Barbier and Ludwig-Mayerhofer, 2004). But this kind of conditionality has also been sporadically mooted, in a variety of diﬀerent countries, in relation to policy themes as diﬀerent as the use of family beneﬁts to promote good parenting, the modiﬁcation of conditions for access to certain health beneﬁts to produce healthy lifestyle choices, or the conditioning of housing beneﬁts on good neighbourliness and the avoidance of ‘anti-social behaviour’. Our overall speciﬁcation or conceptualization of the universe of levels and levers of conditionality in social programmes is summarized in Figure 8.1. As the two closed arrows in the ﬁgure are intended to suggest, these three types of conditions and conditionality can further, and importantly, be understood as occupying distinctive positions on the spectrum of underlying

bases for risk management in welfare states. While an emphasis on risk or membership category deﬁnitions thus conﬁrms the basis of the risk management in socially deﬁned status, an emphasis on constraints or requirements related to conduct gives more weight to individual behaviour as the basis for access to social resources and goods. The standard eligibility criteria for social beneﬁts occupy a somewhat intermediate and indeterminate place on this spectrum; though eligibility criteria are largely impersonal and their fulﬁlment gives automatic access to a status, they have often been deﬁned in practice – as the traditional basis of social insurance in past work performance best demonstrates – to simultaneously but indirectly place certain kinds of behaviour (i.e. ‘good work habits’) at the centre of the social citizenship relationship, too. Notwithstanding such ambiguities, we can nonetheless hypothesize that a shift in the nature of the social citizenship relationship should in principle be reﬂected in a changing balance between category, circumstance and conduct conditions, and thus be identiﬁable by scrutinizing actual changes in the setting of category deﬁnitions, eligibility and entitlement criteria and behavioural constraints in a particular social programme. It is to applying the conditionality framework to look for shifts of this kind in reforms to provision for the unemployed in four European countries that the remainder of this chapter is largely devoted.

APPLYING THE FRAMEWORK: THE CASE OF UNEMPLOYMENT PROVISION The case of unemployment provision is likely to oﬀer a good test of the utility of our framework for a number of reasons. Firstly, unemployment

176

State generosity, social rights and obligations

is perhaps the social risk which calls for, and critiques of, a ‘new paradigm’ of social protection have been most insistent in recent years (see also Kvist in Chapter 9 of this volume). It is also an area where there has been – in a context of historically high unemployment and (in part a result of other reforms) rapidly changing labour markets – quite considerable legislative activity, but where the real impact and thrust of changes in diﬀerent national contexts often remains unclear (e.g. is activation a form of retrenchment?). Finally, unemployment protection is a sector in which legislators could plausibly adjust all three levels and levers of conditionality, and where any cross-national similarities and diﬀerences in patterns of readjustment and deployment should thus be particularly evident. This will be illustrated below. To capture such patterns, a relatively long time period is required. Our analysis covers roughly the quarter-century from the beginning of the 1980s to around 2004 or 2005. It includes four European welfare states, Denmark, France, Germany and the UK. Though we acknowledge that certain levers of conditionality can in the sphere of unemployment policy only be eﬀectively turned at the ‘street level’ – one thinks here of the eﬀective implementation of behavioural conditions by employment service oﬃcers or unemployment beneﬁt administrators – for feasibility the data used are based only on major legislative changes in unemployment insurance.1 Below we sketch proﬁles of legislative trajectories oriented to our framework on the basis of these data, which are listed in full in the chapter appendices. Two points should be noted here. First, the following discussion is based on legislative activity that aﬀected one or several aspects of conditionality within unemployment support in four European countries (see Appendices A to D). The appendices therefore are not intended to cover all major types of legislation in the ﬁeld. Once again emphasizing the complementary nature of the conditionality approach suggested here, any decisions regarding the level of beneﬁt, for example, are excluded because changes therein do not aﬀect the conditionality as deﬁned above. Second, the appendices document legislative changes, and the direction of changes (tightening or relaxing beneﬁt conditionality). They thus document politically binding decisions over time within a particular country, rather than actual degrees of conditionality that could be compared across countries. In other words, legislative activity monitored here allows statements about the trajectory and frequency of changes in, for example, eligibility requirements, but does not provide information on the actual speciﬁcation of such requirements in the four countries. In principle such information, as well as data relevant for other levels of conditionality, could also be collected, allowing comparative judgements to be made regarding the strictness of national welfare state

programmes at a particular point in time, as well as relative to the direction and nature of change over time. While such an endeavour is beyond the remit of this chapter, the following analysis can be regarded as a ﬁrst step for such a comprehensive cross-national analysis of conditionality. The United Kingdom A conditionality framework sheds light in a particularly interesting manner on the nature of the British trajectory of reform in unemployment protection over the past 25 years. At a time of very high and persistent unemployment during the 1980s and early 1990s, UK policies concentrated mainly on tightening conditionality at the ﬁrst and second levels (see Appendix A). For example, important category redeﬁnitions reduced the potential pool of people eligible for unemployment support through the introduction of incentives to the over 60s to retire early (1981), the exclusion of almost all those under the age of 18 from eligibility to unemployment support (1988), and the removal of students from the unemployment risk pool a few years later (1990). The second level of conditionality (governing eligibility) was also frequently and consistently tightened between 1980 and 1996 when the Jobseekers Allowance was introduced. Numerous adjustments resulted not only in the abolition of (limited) ‘Bismarckian’ elements of British unemployment insurance (notably earnings related supplements), but also in a substantial erosion of the traditional ‘Beveridgean’ insurance logic. This has been achieved through a series of curtailments and by making the system less accessible for those with less stable employment and contributory records. As a result, means tested beneﬁts have become the clearly dominant form of support available to unemployed people in the UK today. Whereas in the late 1970s more than half of all unemployed received contribution based support, 20 years later the rate had declined to about 16 per cent (Clasen, 2005: 59). Interestingly, since 1997 Labour governments have refrained from further adjustments of the second level of conditionality, i.e. leaving beneﬁt eligibility and entitlement criteria unchanged. However, both the ﬁrst and third levels of conditionality have moved to centre stage. Regarding the third level (conditions of conduct), Labour continued and reinforced a trend which had already begun under Conservative governments in the late 1980s, namely inﬂuencing the behaviour of unemployed beneﬁt claimants by tightening the conditions of active job search, relaxing the deﬁnition of appropriate employment and toughening sanctions for non-compliance (Finn, 1998). More ‘positive’ forms of activation were essentially limited to providing increased help with job search, through initiatives such as ‘Restart’ interviews. As well as making compulsion in labour market policy

178

State generosity, social rights and obligations

more explicit, Labour’s New Deal initiative since 1997 has built on the Restart concept with respect to intensive counselling and employment guidance for the unemployed; but it has also reintroduced a few investment intensive training and job subsidy programmes. This growing emphasis on activation has, in turn, encouraged further reform initiatives at the ﬁrst level of conditionality. In a de facto reversal of the tightening of category membership during the 1980s and early 1990s, the Labour government has increasingly widened the remit of New Deal programmes, from the unemployed originally to potentially all workingage beneﬁciaries of social support (the disabled, lone parents, jobless partners of the registered unemployed) today. At the delivery level, the so-called Jobcentre Plus is now the point of contact not only for the registered unemployed, but for all working-age beneﬁt claimants. We see a loosening of the deﬁnition of unemployment, or at least blurring of the boundaries between unemployment and other social risks. This has allowed UK labour market policy to gradually shift from an emphasis on unemployment to an increasing emphasis on ‘worklessness’ (Clasen, 2005). In other words, having settled on a new and seemingly stable level of secondary conditionality, with strict access to insurance and a dominant needs based approach, recent activities have focused on the ﬁrst and third levels of conditionality. Notably, this means that past activities – the status and origin of claimants (contributions, employment status) – have all but become irrelevant. Instead, the new British conditionality logic is both wider (beyond unemployment) and more focused on work tests and employability criteria than previously. Over the past 25 years, the overall pattern could thus be described as a gradual progression down through the levers of conditionality, from adjustments at the primary level (category deﬁnition), accompanied and gradually superseded by successive initiatives tightening conditionality at the secondary level of conditionality, before ﬁnally a concentration on tertiary conditions (activation) took over. This activation logic has seen a small move ‘back up’ the levels of conditionality, with a partial reversal of earlier changes to primary-level (category) criteria. Germany Also faced with fast rising levels of unemployment during the early 1980s and even more so the 1990s, the reform proﬁle in Germany diﬀered considerably from that in the UK. As a more Bismarckian social insurance oriented country, German unemployment insurance oﬀers a multitude of levers at the second level of conditionality, i.e. those that govern eligibility and entitlement criteria. In addition, the governance of unemployment support as a whole (until recently a de facto three-tier system) has provided

particular incentives for adjusting levers that would result in cost transfers between the federal level, the unemployment insurance fund, other social insurance funds and local authority budgets (Clasen, 2005). The annual budget of the unemployment insurance fund triggered several adjustments at the second level of conditionality during the 1980s and 1990s. Some of them relaxed conditions of beneﬁt receipt, through for example the repeated prolongation of entitlement for older unemployed with longer contribution records between 1985 and 1987 (see Appendix B). By contrast, incremental legislative change tightened eligibility conditions of unemployment protection at the margins of the labour market, e.g. for those with shorter contribution periods such as job starters and those with repeated spells of joblessness (1982, 1994, 1998). Unlike in the UK, the ﬁrst level of conditionality remained largely oﬀ the reform agenda during the 1980s, at least within unemployment insurance and notwithstanding the de facto category redeﬁnition of older beneﬁt claimants who made use of extended unemployment beneﬁts as a form of quasi pre-retirement (Trampusch, 2005a). As for the third level of conditionality, tighter suitability criteria (governing regulations of job oﬀers which can be turned down without risk of beneﬁt sanction) were introduced as early as 1979 (Clasen, 1994: 153), and redeﬁned again in later years (1982, 1998). There was, however, little emphasis on behavioural job search or activation criteria at federal level until the late 1990s, and the activation type policies were introduced with much less vigour than in the UK. While local authorities have had the right to ‘activate’ long-term unemployed persons for some time, and some have made extensive use of this not least on the basis of ﬁnancial considerations (Buhr, 2003), prior to 2005 claimants of unemployment insurance have not been subjected to a routine form of mandatory activation. The major recent labour market reform in Germany (the so-called ‘Hartz’ reform) has however had a considerable impact on all three levels of conditionality. Apart from other changes (see Kemmerling and Bruttel, 2006) legislation merged unemployment assistance and social assistance into unemployment allowance II (ALG II) for ‘employable persons’, thereby expanding the category of unemployed welfare state clients (ﬁrstlevel conditionality). This change resulted in a steep and sudden rise in oﬃcial unemployment in January 2005 when the legislation came into eﬀect. Recipients of ALG I were aﬀected by a shortening of beneﬁt entitlement while the means test for claimants of unemployment assistance was tightened signiﬁcantly (second-level conditionality). Moreover, beneﬁts payable under the pre-existing unemployment assistance arrangements were earnings related, whereas the new ALG II is ﬂat rate and no longer related to former earnings. Finally the reform has made steps towards an

180

State generosity, social rights and obligations

activation oriented policy regime that regulates behavioural aspects of job seekers more strictly. This applies to ALG II recipients and beneﬁt claimants under the age of 25 in particular, who are supposed to be oﬀered, and to accept, a job or an ‘activation’ programme instead of beneﬁt receipt. At the time of writing it remains unclear whether this regulation is being implemented accordingly. France The recent trajectory of unemployment beneﬁt reform in France in many respects parallels that seen in Germany, not least in the overwhelming concentration of reform initiatives at the second level of beneﬁt conditionality. The contribution ﬁnanced French unemployment insurance system has, furthermore, in the main coped with a context of consistently high unemployment since the early 1980s by tightening eligibility conditions rather than reducing beneﬁt rates. Important reforms over the period 1982–84 tied beneﬁt eligibility and entitlement more closely to prior contributions, and created a separate tax ﬁnanced and less generous system (the ‘solidarity system’) alongside unemployment insurance for some of those with inadequate contributory records. Further reforms in 1992 tightened the contributory requirements for unemployment insurance once again, and deepened the dualism of the unemployment protection system. Although some of these cuts have been partially repaired by other reforms, enacted notably in the period of stronger economic growth at the end of the 1990s, the dualism has not been challenged. Indeed, spare resources have often been devoted to improving beneﬁts for certain groups of insured claimants, as was the case for example of a 1997 reform which created a special, more generous, unemployment beneﬁt payable up to the age of 60 for workers with long contribution records. Meanwhile, coverage of unemployment insurance fell by around 10 percentage points in the 1990s. In sum, similarly to Germany, the main story of French unemployment beneﬁt reform in recent decades has been one of using the levers of secondary conditionality to increase the diﬀerentiation in rights to unemployment beneﬁts (cf. Daniel, 2000). Explicit reforms to the ﬁrst level of conditionality have been far more rare, though – as in Germany – the unemployment insurance system was used in the early 1980s to encourage the eﬀective withdrawal of older workers from the labour market (Daguerre and Palier, 2006). These incentives remain in place today, and were in fact somewhat strengthened by a reform in the late 1990s. Another form of category redeﬁnition has been more implicit, with the progressive institutionalization of the Revenu Minimum d’Insertion (RMI), introduced in 1988, as the ‘third tier’ of the

Measuring change within welfare states

181

French unemployment protection system (Audier et al., 1998). Though the recipients of the RMI may remain registered as unemployed, unemployment is not itself a condition for the receipt of the RMI. Furthermore, this beneﬁt still rests on a mix of rights and responsibilities that are quite distinct from those found in formal unemployment protection. This is notably the case with respect to tertiary forms of beneﬁt conditionality. Although the RMI has always been – at least formally – conditional upon the beneﬁciary agreeing to individualized reintegration activities, this principle had until very recently gained little ground in formal French unemployment beneﬁt policy. Only in 2000 was a bolder proposal for the systematic conditioning of unemployment insurance beneﬁts on positive job search activities brought forward, with the creation of the so-called PARE (Plan d’Aide au Retour à l’Emploi) (Freyssinet, 2002; Kerschen, 2005). Though there have been diﬃculties in the implementation of the latter measures, and the corresponding capacity of the unemployment insurance system to oblige participation in training or job search activities remains uncertain as a result, initiatives outlined in the recent ‘law on social cohesion’ and intensiﬁed by the new de Villepin government suggest that tertiary conditionality may belatedly be – again, as in Germany – becoming a more important lever in the reform of French unemployment beneﬁts. Denmark As in the UK, a clear Danish reform proﬁle can be detected since the early 1980s, with similarities in both the ﬁrst and the third level of conditionality. However, unlike in the UK there has been no eﬀective shift in distributive principles as a result of tighter conditionality at the second level. Instead, the social insurance notion within unemployment support has been maintained, albeit in a form that is still distinctively diﬀerent – and much more ‘Beveridgean’ in character – than the one in Germany or France. Danish unemployment beneﬁt entitlements are thus still among the most generous in Europe, though not for short-term unemployed persons on above average earnings since beneﬁt thresholds and ceilings make transfers resemble a ﬂat-rate system for a large section of unemployed persons. Danish governments tightened the deﬁnition of unemployment in the late 1970s and early 1980s, making considerable use of labour market exit strategies in the face of high unemployment. The early retirement programme efterløn was introduced in 1979 with the explicit aim of redrawing the category deﬁnition of ‘unemployment’ for workers of age 60 and over (ﬁrst-level conditionality). However, unlike in the other three countries, thereafter several other levers were adjusted at the ﬁrst level of conditionality which were aimed at widening or at least consolidating the potential membership

182

State generosity, social rights and obligations

in unemployment protection, particularly for long-term unemployed (1985) and younger age groups with the introduction and later extension of the ‘youth beneﬁt’ and ‘youth allowance’ (1990–92), albeit coupled with the right and obligation to accept activation oﬀers. Thus, in common with the UK, Denmark tightened the third level of conditionality as early as the late 1980s and early 1990s, and concentrated increasingly on this strategy from 1993 onwards. Also as in the UK after 1997, the focus on activation was coupled with a reversal of the previous policy direction at the ﬁrst level of conditionality, making efterløn ﬁnancially less attractive (1998–2000) or extending the activation principle to social assistance (1997). There has been rather less reform activity at the second level of conditionality in Denmark than in the other three countries. Furthermore, the direction of change has not been unequivocal, as in the UK. Thus, though eligibility conditions for unemployment insurance were tightened in 1985, and a lower-rate beneﬁt was introduced for those who no longer had access to full beneﬁts, this reform was overturned in 1988, when full-rate beneﬁts were reinstated. In the second half of the 1990s, Danish governments made considerable cuts in unemployment beneﬁt rights. The bulk of these, however, have come neither through selective reductions in beneﬁt levels nor in tighter eligibility criteria. The latter became stricter in a reform in 1994 (Kvist, 2002), but remain relatively loose in comparative perspective. Supporting about 85 per cent of all unemployed in 2004 (Danmark Statistik, 2005: Table 160), the Danish unemployment insurance system remains one of the most encompassing programmes in Europe. Nevertheless, secondlevel conditionality was tightened via several changes in the maximum duration of beneﬁt entitlement, which was reduced in successive stages from seven to four years between 1993 and 1998. Danish reform eﬀorts have concentrated not so much on preventing inﬂows into unemployment beneﬁt but more on speeding up outﬂows, through considerable reform activity at the third level of conditionality, i.e. the turn towards activation principles in the 1990s. Since 1993 there has been a vast expansion of activation measures, with a particular emphasis on training programmes, which are both a ‘right and a duty’ for the unemployed (e.g. Goul Andersen, 2002). The length of time that it is necessary to be unemployed before being subject to this ‘right and duty’ has been reduced in successive reforms, and since 1998 is one year for the adult unemployed and six months for the young. Summary How can these stylized and necessarily simpliﬁed reform trajectories be compared? Based on the discussion above and information provided in

Figure 8.2 Conditionality shifts in unemployment beneﬁt reforms in four countries Appendices A to D, Figure 8.2 provides a rough picture of legislative proﬁles. It shows that in all four countries reforms can be identiﬁed which altered all three diﬀerent levers of conditionality, i.e. category deﬁnitions (ﬁrst level), eligibility and entitlement criteria (second level) and behavioural conditions (third level) attached to continuous beneﬁt support. A chronologically sequential path is conspicuous in the UK where governments focused on the ﬁrst and second levels during the 1980s, on the third level in the late 1980s, and completed the second level in 1996. Since then Labour governments have almost exclusively altered the ﬁrst and third levels in a drive towards what is now called ‘activation’. The Danish reform proﬁle is very similar to the British at the ﬁrst and third conditionality levels, but diverges at the second level. Unlike in the UK, there has been little tightening of the conditions of circumstance required for access to the unemployment protection system and the traditional notion of unemployment insurance has remained dominant, albeit coupled with a stronger conditionality at the third level. Very much in contrast to both the UK and Denmark, French and German reforms were distinctive in three respects. First, the second level of conditionality (eligibility and entitlement criteria) remained the privileged policy lever in these two countries. Second, within this domain, policies had a ‘diﬀerential’ focus in France and Germany, altering access to unemployment support relatively little for some groups (typically workers with long

184

State generosity, social rights and obligations

contributory work records) but tightened eligibility conditions for groups which are less ﬁrmly entrenched in the labour market. Both Germany and France have thus deepened the dualism of their respective unemployment protection systems in recent decades. By contrast, both Denmark and the UK have maintained or created much more uniform conditions within their respective systems (see Clasen and Clegg, 2006a). Finally, while all four countries made use of labour market exit strategies by (de facto or de jure) changes in the category deﬁnition of unemployment support (ﬁrst-level conditionality), France and Germany maintained such approaches for much longer during the 1990s, and also turned to ‘activation’ strategies (tightening third-level conditionality) much later than Denmark and the UK. This framework for analysing change in the conditionality of unemployment support helps to highlight a certain number of potentially salient cross-national similarities and diﬀerences. Firstly, until 1995 there appears to be no particularly strategic reorientation in the management of the risk of unemployment in any of the countries, with the main focus being a general tightening of available conditionality levers – retrenchment – across all cases, albeit with a generally broader range of conditionality levers being used to this eﬀect in Denmark and the UK. Since 1995, however, it is possible to identify a clear change in the way that unemployment is managed in these two countries, with levers of eligibility or entitlement increasingly untouched on the one hand, and with status based risk management conditions becoming less, and behaviour based risk management conditions more, relevant. Over and above the continuing and often highlighted diﬀerences between the approaches to unemployment policy in the UK and Denmark (e.g. Torﬁng, 1999; Barbier, 2004), the framework shows a certain structural aﬃnity in the way that the management of the unemployment risk is being reconceptualized in these two countries. This distinguishes them very clearly from France and Germany, although the recent reforms in Germany – and notably the broadening of the deﬁnition of unemployment and concomitant tightening of behavioural requirements – suggests that the Federal Republic too may be increasingly shifting towards a new model of risk management in unemployment, rather than merely adjusting the existing framework.

CONCLUSIONS The aim of this chapter was to try to elaborate a framework through which the extent of certain changes in welfare states, and notably the widely touted notion of an emergent new ‘model’ or ‘paradigm’ within the social citizenship relationship, could be empirically investigated and scrutinized

Measuring change within welfare states

185

in cross-national analysis. As argued in its ﬁrst part, these kinds of changes are diﬃcult to capture with the standard expenditure, macro-institutional or ‘social rights’ based dependent variables that are commonly deployed in welfare state research. By identifying lower-level institutional features that are more pertinent to the dynamics expressed by the qualitative leitmotifs of welfare state change, we have shown that it is possible to develop comparative benchmarks against which policy trajectories can be judged, concentrating on particular policy programmes and their inherent dimensions and dynamic balance of conditionality. As its application in the analysis of unemployment beneﬁt reforms in four countries has shown, such benchmarks are capable of systematically identifying patterns of similarity and diﬀerence in legislative activity and direction of welfare state change. Viewed in isolation, such a framework of course has a number of limitations. As emphasized earlier, it is mainly a device for comparing the emphasis, direction and structure of national reform trajectories over time. It thus can obviously not help analysts interested in a direct comparison of policy outputs. The conditionality framework could not tell us, for example, that unemployment beneﬁts remain much more generous and encompassing in Denmark than in the UK. Nor could it tell us that levels of investment in active labour market policies for every unemployed person are far lower in the UK than in Denmark, and indeed than in Germany or France. Our motivation here, however, has not been to develop a ‘competitor’ to the more habitual indicators that can better inform us of these dimensions of cross-national variation (in these two examples, social rights indicators and ‘adjusted’ social expenditure indicators, respectively). Rather, it has been to develop a framework that could complement these more standard indicators by capturing other dynamics of change within which other dimensions of variation can be nested. Though, say, the British situation seems as unlike the Danish as it is possible to be on indicators of the generosity of social rights for the unemployed or investment in active labour market policies, it is important for our explanatory perspectives and causal analyses to know – and be able to show – that the UK is in certain structural respects following a much more similar reform trajectory to Denmark than is either France or Germany. The above indicates another advantage of the framework suggested here, namely that of giving rise to new research perspectives or questions. In our example, it would lead us to ask about the causes of cross-national similarities and variation, linking the Danish and British reform proﬁles in contrast to the French and German. In keeping with Part I of this volume, directed at the ‘dependent variable’ problem in comparative welfare state analysis, this chapter has deliberately not engaged in explanatory analysis (for this, see Clasen and Clegg, 2006b). Instead, it has sought to highlight

186

State generosity, social rights and obligations

the substantive advantages of a framework that can be used to tease out and demonstrate the patterns and logics at work in social policy reform that are either missed or not systematically treated within more standard analytical approaches. Though we have focused here on unemployment beneﬁts, our framework could indeed usefully be applied in a similar way to enrich cross-national analysis of a number of other areas of welfare state reform – such as family beneﬁts, disability provision etc. – where similar or equivalent qualitative shifts in risk management, or the social citizenship relationship, seem likely. At a minimum, and more methodologically, this kind of framework can help to steer and discipline qualitative crossnational analysis, limiting the number of potentially relevant observations and organizing ﬁndings on a common analytical grid. This in itself would help to promote the generation of more systematic cross-national knowledge on the very many areas of welfare state variation and dynamics of welfare state change that are easily overlooked when it is the available dependent variables that guide the questions we ask in comparative analysis, rather than the other way around.

9. Exploring diversity: measuring welfare state change with fuzzy-set methodology Jon Kvist1 INTRODUCTION Is the glass half-empty? Is it more empty than full? Such questions are often linked to judgements which concern qualitative states and changes in degree and kind. Abounding in comparative studies, such judgements bring forward issues of how best to conceptualize and measure. In comparative studies of the welfare state they prompt reﬂections on what constitutes the welfare state (see Bonoli, Chapter 3 in this volume), how to operationalize it and how to measure change over time and space. Comparative welfare state research has made signiﬁcant progress in the theoretical understanding of the welfare state itself, not least due to a dialogue between qualitatively and quantitatively oriented studies (Amenta, 2003). Since 1990, when Gøsta Esping-Andersen published Three Worlds of Welfare Capitalism, a common starting point has been the distinction between diﬀerent types of welfare state regime: identifying a liberal, conservative and a social-democratic welfare state regime. In short, diversity – the co-existence of similarities and diﬀerences – characterizes diﬀerent welfare states. Comparative research however has made much less progress in the measurement of welfare state and welfare state change (see Clasen and Siegel, Chapter 1 of this volume). A lack of consensus about how to measure either is the main reason why scholars disagree on the direction and magnitude of recent change in social policy, i.e. whether reforms amount to fundamental or marginal change (Clayton and Pontusson, 1998 with Pierson, 1996; or Gilbert, 2002 with Kvist, 1999). Of course, neglecting issues of measurement is not unique to comparative welfare state research. In a review of macro-level comparative studies, Bollen et al. (1993) found that although researchers acknowledge problems of measurement, they largely ignore their consequences. And yet, because 198

researchers are often unable to apply statistical tests of data validity and reliability because of the small number of countries (the small-n problem), they have a particular need to reﬂect on and tackle measurement problems in alternative ways. Otherwise, they run the risk of making (false) heroic conclusions on small n (Lieberson, 1991). Concentrating on the connection between theory and data, a relationship also known as measurement validity (Adcock and Collier, 2001), the subsequent discussion could apply to a large number of substantive areas. However I concentrate on problems of measurement in comparative welfare state studies not only for illustrative purposes but also because this is a large area of research which has paid relatively little attention to methodological aspects of this kind, with some notable exceptions, such as Castles (2002), who defends the use of social expenditure as an indicator for measuring welfare state change. The key question is whether measurement meaningfully captures the ideas contained in concepts and ideal types. Although social expenditure is ‘widely seen as providing misleading indicators of the nature and extent of welfare state activity’, Castles (2002: 618) argues that we should reﬁne the approach as a ‘second best solution’. This chapter oﬀers an alternative approach to measurement and a very diﬀerent strategy, that of formulating a new way of going about measurement by using fuzzy sets and axioms in fuzzy-set theory. The aim is to advance the application of fuzzy-set theory as a new method for conceptualization and measurement (see Ragin, 2000 for a broad introduction to fuzzy-set social science). I argue that the fuzzy-set approach is particularly useful for assessing diversity and change across a limited set of cases, and that it can overcome some of the problems typically related to measurement validity and precision. In other words, using fuzzy sets help to assess whether the glass is half-full or half-empty, or how, if at all, the welfare state is retrenched or restructured. Introducing the issue and focusing on key theoretical concepts, the subsequent section concentrates on welfare state diversity (1). The following sections argue that cases and ideal types can be viewed as conﬁgurations of concepts (2) and discuss how concepts can be conceived and operationalized as fuzzy sets (3). Finally the chapter demonstrates how to formally examine concepts and ideal types with fuzzy-set theory.

WELFARE STATE DIVERSITY AND SOCIAL CITIZENSHIP One set of burning questions in comparative welfare state research concerns whether the welfare state is undergoing retrenchment or restructuring or

Residual Figure 9.1

Institutional The dichotomy of residual and institutional welfare states

whether it is resilient to change (Mishra, 1990; Kvist, 1997; Taylor-Gooby, 2002). Before 1990 it was common to distinguish between residual and institutional welfare states (Titmuss, 1958; Wilensky and Lebeaux, 1958; Alber, 1988), locating real welfare states on a continuum stretching from a residual welfare state at one end of the spectrum to an institutional welfare state at the other (Figure 9.1). According to the dominant thinking for the last 30 years, cash transfers in the institutional welfare state were typically universal and generous, whereas beneﬁts in the residual welfare state guaranteed a minimum but were targeted and reserved for the deserving poor. Welfare states, therefore, were perceived as moving only in two directions: either expanding to become more institutional, or retrenching and becoming more residual. Such views regarded historical trajectories of welfare states as initially going through a phase of expansion, eventually reaching a point of maturity (Flora, 1987b) or turning point leading to retrenchment (Mishra, 1990) from the mid 1980s onwards. Advanced by Esping-Andersen (1990), the idea that welfare states come in three types, and not two, did not alter the notion of welfare states moving either in an institutional or a residual direction. Indeed, Paul Pierson’s (1994) inﬂuential text on change and politics of the welfare state mainly added a point of no return, i.e. welfare states’ resilience to change. However, since the mid 1990s a growing number of scholars have argued that we are witnessing changes which can not be captured by unilinear, onedimensional conceptions of more, the same or less welfare state (e.g. Kvist, 1997). Revisiting Esping-Andersen’s (1990) Three Worlds of Welfare Capitalism, researchers pointed out that welfare state ideal types reﬂect diﬀerent political ideological notions of social citizenship constituted by social rights and obligations (Marshall, 1950) which, in turn, are manifested in speciﬁc conﬁgurations of beneﬁt characteristics, such as generosity and eligibility. To illustrate, the liberal welfare state model depicts an ideal type where beneﬁts are meagre and targeted at the needy, positioned in the lower left hand quadrant of Figure 9.2, while generous beneﬁts in the conservative model are selective, favouring labour market insiders, thus placing its ideal typical position in the upper left hand quadrant. The ideal typical socialdemocratic welfare state model can be found in the upper right hand quadrant, granting both universal and generous beneﬁts. Finally, the combination of easily accessible but not generous beneﬁts (lower right hand quadrant – and not caught by Esping-Andersen’s trilogy) – is perhaps best

described as the Beveridgean, the lib-lab model (Room, 1979), or, simply, the labour model. Methodologically, the above describes welfare state diversity on a lower level of abstraction, i.e. that of social rights. With reference to Robert Adcock and David Collier (2001), the welfare state is regarded as a ‘background concept’ with broad constellations of meanings and understandings whereas social citizenship is a ‘systematized concept’ that entails a speciﬁc formulation. Depending on speciﬁc research interests, systematized concepts other than ‘social citizenship’ might have been employed to inform the study of the welfare state. Whereas ‘social citizenship’ (or ‘social rights’) are theoretical concepts relating to the output, or policy, side of the welfare state, more outcome oriented research might opt for concepts such as ‘autonomy’ or ‘equality’, whilst more input oriented studies might make use of concepts such as ‘welfare eﬀort’ or ‘popular support’. The use of social rights as a systematized concept allows for the identiﬁcation of diﬀerent combinations of ‘less’, ‘the same’ or ‘more’ of the two constitutive dimensions of social rights, accessibility and generosity. In turn, this facilitates the investigation of multidimensional change, or a process described as ‘restructuring’. For example, if the generosity of a particular beneﬁt (I) improves between one point in time (t1) and another (t2) while it simultaneously becomes more diﬃcult to access (see Figure 9.2), it could be argued that the direction of change is towards a conservative welfare state model. The same may also be true in instances where one dimension remains stable and the other dimension enhances a trait which is characteristic of the conservative welfare state model (see II in Figure 9.2). Whether the observed alteration amounts to a qualitative change depends on the start and end points of the beneﬁt trajectory. For example, in Figure 9.1, beneﬁt I is subject to a change in degree, not in kind or type. Put diﬀerently, change here means that I has moved closer to the ideal type of the conservative welfare state model. The closer to the corner, the more the beneﬁt reﬂects the ideal type. The change within beneﬁt I illustrates a situation where it belongs more strongly to the ideal type of the conservative welfare state regime at t2 than at t1. The change, therefore, is quantitative. Beneﬁt II is subject to both quantitative and qualitative change. The quantitative change implies that beneﬁt II becomes much less accessible. Moreover, as Figure 9.2 shows, beneﬁt II is in the upper right hand quadrant at t1 and in the upper left hand quadrant at t2. This shifting of corners reﬂects a qualitative change. The example demonstrates how beneﬁt II moves from belonging to a social-democratic welfare state model to belonging to that of a conservative welfare state model. Starting points also matter for the assessment of change. Although the change in beneﬁt II may be argued to be stronger and of a more qualitative

nature than the change in beneﬁt I, Figure 9.2 still shows that beneﬁt I, rather than beneﬁt II, is closer to the ideal typical corner that symbolizes the conservative welfare state model.

CONFIGURATIONS OF CONCEPTS Social citizenship is constituted of both rights and obligations, and so far we have only set out two dimensions of rights. Looking only at rights and neglecting obligations is in line with most conventional analyses of social citizenship as exempliﬁed by the Social Citizenship Indicator Project (SCIP) at SOFI, Stockholm University, a database which has information on coverage and generosity, but none on obligations. Twenty years ago, researchers and politicians might have been able to justify this neglect in theory and political practice. This is no longer the case. With the general shift in welfare policies towards more active, employment centred objectives, there has been an increasing emphasis on individual obligations, both prior to and during the receipt of beneﬁts. In Figure 9.3, a third dimension, obligations, has thus been added to the core analytical concept. The further a beneﬁt is situated towards the back of this cube, the stronger the attached obligations and vice versa. As

Obligations Accessibility

Figure 9.3

Analytical property space for social citizenship

a consequence of adding obligations as a third dimension, four new ideal types emerge which may be labelled ‘new’ in contrast to the original four ‘old’ ideal types. For example, the ‘old social-democratic’ welfare state regime is located in the upper front right hand quadrant, while the ‘new social-democratic’ welfare state regime, with a stronger emphasis on individual obligations, is closer to the upper back right hand corner. In a Weberian sense the corners of the cube constitute eight ideal types and can thus be regarded as yardsticks, measuring how close or distant given empirical phenomena are to or from these ideal types and to or from each other (Weber, 1949; Kvist, 1999). In the analysis here, the relevant measurement is the extent to which national welfare states conform to the various ideal typical welfare state regimes, and to what extent national welfare states are moving closer to each other, so-called ‘convergence’, or away from each other, ‘divergence’ (see also Chapter 10 by O’Connor in this volume). Another way of illustrating the diversity and analytical constructs applied here is the use of a truth table, displaying the combinations which are possible (Lazarsfeld, 1937). Table 9.1 shows this method for models of social citizenship, arising from simple yes-or-no dichotomies. Alternatively, a simple eight-cell table might be used (see Table 9.2) which, as Becker (1998) emphasized, has the advantage that the researcher can add a fourth variable by inserting the value in each cell. From the vantage point of concepts and ideal type analysis however, what the eightcell table shares with truth tables is the disadvantage of requiring aspects to be dichotomies.

Here the interest is in substantive issues which are insuﬃciently captured by dichotomies, such as ‘yes’ or ‘no’. Such an approach does not allow the assessment of changes, both small and large, in relation to one another and to some analytical constructs. But how can the conformity of cases to ideal types, and to each other, be constructed and measured? The remainder of this chapter discusses the ways in which fuzzy-set theory may provide innovative and powerful answers to this question.

CONSTRUCTING FUZZY SETS ON CONCEPTS Fuzzy sets are not fuzzy in the sense of being imprecise or ambiguous. On the contrary, fuzzy sets should be designed to accurately reﬂect theoretical concepts and analytical constructs which have a precise meaning to those researchers using them. Fuzzy sets provide a way of operationalizing a concept into a 0-to-1 metric, from being ‘fully out’ to ‘fully in’ a set. This requires drawing a demarcation line between ‘A’ and ‘not-A’. In the analysis here, operationalizing implies the construction of sets that reﬂect accessibility, generosity and obligations. These, in turn, will – in diﬀerent conﬁgurations – constitute diﬀerent ideal types of welfare states.

205

Lines between diﬀerent membership sets are drawn on the basis of substantive and theoretical knowledge. By having to draw a line or curve reﬂecting the particular concept under consideration, the researcher centres his or her focus on the concept rather than on the variables themselves. Focusing on the concept moves the analysis closer to the theoretical body that deals with concepts in the ﬁrst place. A reference to ‘generous beneﬁts’ is more informative than speaking of ‘beneﬁts with a net replacement rate above X percentage’. Moreover using this term also helps to minimize measurement bias, that is, the gap between theory and reality. While ‘fully generous’ and ‘fully not-generous’ refer to extremes, many intermediary concepts link these two categories. Depending on the substance of the concept and the raw material, various fuzzy category intervals may be used (see Ragin, 2000). Here a nine-value fuzzy set is applied, where continuous fuzzy scores between 0 (fully out) and 1 (fully in) indicate partial membership in the following way: ● ● ● ● ● ● ●

scores from 0.83 to 0.99 is almost fully in; 0.67 to 0.82 is fairly in; 0.51 to 0.66 is more or less in; 0.5 is the cross-over point where the case is neither more in nor more out; 0.33 to 0.49 is more or less out; 0.17 to 0.32 is fairly out; 0.01 to 0.16 is almost fully out.

Using this nine-value fuzzy set throughout the chapter helps to translate interval fuzzy membership scores into verbal concepts or verbal qualiﬁers. For example, if a beneﬁt has a fuzzy score of 0.75 the score is presented as a ‘fairly generous’ beneﬁt, a fuzzy score of 0.60 translates to a ‘more or less generous’ beneﬁt. Constructing fuzzy sets involves two steps: ﬁrst to establish empirical indicators for the fuzzy set, and second to calibrate the fuzzy set. The following two subsections elaborate these steps. Empirical Indicators To reduce the gap between theory and reality, empirical indicators are needed which reﬂect the chosen concepts as closely as possible. The quest for useful empirical indicators should be guided by theories and substantive knowledge with reﬂections made explicit. Applying the example of social citizenship, three sets have been identiﬁed which reﬂect theoretically important concepts. The ﬁrst set, accessibility of

206

State generosity, social rights and obligations

unemployment beneﬁts, is measured by an index based on scores for the scope of application and various eligibility criteria (e.g., work demands, deﬁnition of employment records, and membership requirements, if any). The set for generosity of unemployment beneﬁts is measured by net replacement rates that express the ratio of beneﬁts to former wages after taxation. This ‘generosity’ measure has become common in the literature. Here the net replacement rate for a single person with previous earnings at the level of the Average Production Worker (APW) has been used. This has two main caveats: ﬁrst, net replacement rates calculated at other points in the income interval may suggest deviating values of generosity. Second, the existence of tax allowances and/or supplements for children may cause diﬀerences in net replacement rates of persons in single individual households and non-single households. Aggregate measures such as average net replacement rates for diﬀerent income and family situations do not indicate how national systems work for any particular population group but simply conﬂate otherwise useful information. As most national unemployment insurance schemes are strongly individualized, and as unemployment is concentrated among groups with lower levels of education, the net replacement rate for a single APW as empirical indicator for beneﬁt generosity seems justiﬁed here. The third set on obligations of unemployment beneﬁt claimants can be measured in numerous ways. Here an index of negative sanctions, as stipulated in legal texts, has been applied. In other words, the measurement reﬂects negative sanctions that may be imposed if a person becomes unemployed voluntarily or because of misconduct, and on beneﬁt claimants who refuse to accept a job oﬀer or participation in an active labour market programme. Acknowledging that the implementation of sanctions may not always follow the letter of the law, legal stipulations give at least an important signal to both administrative authorities and claimants, and can therefore be seen as reﬂecting politicians’ positions on the issue of obligations. Calibration of Sets Having identiﬁed the best possible empirical evidence, how do the data reﬂect theoretical concepts? In practical terms, the best approach is, ﬁrst, to establish when something is fully in and fully out of the set and, second, to ﬁne-tune the set by describing how it looks in the range from fully out to fully in. This calibration of sets must be informed by theoretical and substantive knowledge since it aﬀects the measurement of fuzzy membership scores. Any fuzzy-set analysis is only as good as its sets, making the infusion of knowledge into sets indispensable. The starting point for the accessibility index here is the assumption that people aged between 18 and the oﬃcial retirement age should be able to

qualify for unemployment beneﬁts after six months of employment within a 12 month period, taking into account activities other than ordinary paid work which might count towards eligibility, e.g. training and child caring. If qualiﬁcation is possible under these conditions, the beneﬁt system is deemed to be more easy than diﬃcult to access (i.e. the membership score is greater than 0.5). If these conditions are insuﬃcient for beneﬁt qualiﬁcation, the system is diﬃcult to access (i.e. membership scores lower than 0.5). Table 9.3 shows the translation of raw data – index scores – into fuzzy membership scores and labels. The higher the index score, the easier the access to beneﬁts. For the set on generosity, the ﬁrst qualitative breakpoint occurs when the beneﬁt is fully not-generous. Below this point variation is meaningless since distinguishing between degrees to which beneﬁts exceed ‘fully not-generous’ does not make sense. The second qualitative breakpoint occurs when the beneﬁt is fully generous. Above this point variation is meaningless because distinguishing between degrees to which beneﬁts exceed ‘fully generous’

208

State generosity, social rights and obligations

does not make sense. The third qualitative breakpoint is the cross-over point, where the beneﬁt switches from being ‘more not-generous than generous’ to becoming ‘more generous than not-generous’. According to national consumption surveys (Hansen, 1998) persons cannot maintain any attained standards of living if their income is reduced by four-ﬁfths, as they will soon have to rearrange their ﬁnancial aﬀairs dramatically. Hence, if the net replacement rate is below 20 per cent, we deem it fully not-generous. Having a job or participating in an active labour market policy programme involves costs for mobility and various other expenses. In most countries – for example, Denmark – workers are granted tax allowances to partially cover such costs and participants in active labour market policy programmes may earn something extra before their beneﬁts are reduced. Both the earnings exemption and the tax allowances amount to approximately 10 per cent of the APW earnings in the Danish example. For this reason we label net replacement rates of 90 per cent and more as fully generous. Establishing when beneﬁts are more generous than not is more diﬃcult. We have put the point at 55.5 per cent. For the speciﬁc translation of net replacement rates into fuzzy scores and labels, see Table 9.3. The ﬁnal fuzzy set on obligations concerns the severity of negative sanctions, measured by an empirical indicator of the number of weeks for which claimants may have their beneﬁts suspended and the timing thereof. The earlier strict sanctions are imposed, the higher the score. The longer – and thus more severe – the sanctions, the higher the index score. Table 9.3 also shows the translation of fuzzy membership scores into nine verbal labels, ranging from ‘fully accessible’ to ‘fully not-accessible’. These labels are used for the analysis of the conformity of cases to concepts and ideal types. For example, if a beneﬁt scores 70.2 in the set on generosity this translates as a ‘fairly generous’ beneﬁt. Scoring Cases How can fuzzy sets be constructed? Basically, there are two options. The ﬁrst is to separately investigate each dimension of the policy development; the second is to use formal set theory axioms to study conﬁgurations of sets. This section gives a brief example of the ﬁrst option applied to empirical developments in Denmark. The subsequent section illustrates the potential of applying the second option. In 1990, Danish unemployment insurance beneﬁts were almost fully accessible (see Table 9.4). By 1998, the beneﬁts had become only more or less accessible, because the required work period preceding unemployment increased from 26 to 52 weeks. Beneﬁt generosity fell in the same

period from fairly generous to more or less generous (see Table 9.4). This drop did not result from any direct cuts in beneﬁt levels or in the beneﬁt formulae but came about for two reasons: beneﬁt indexation lagged behind wage developments and the introduction of a gross tax (a so-called ‘labour market contribution’) of 5 per cent in 1994, increased to 8 per cent in 1997. However obligations have seen the most dramatic degree of change. During the 1990s demands on wage and geographical and occupational mobility on the part of unemployed beneﬁt claimants became stronger, accompanied by tougher negative sanctions for the rejection of jobs or training oﬀers. While obligations were fairly lax in 1990, they became almost completely strong by 1998 (see Table 9.4). In other words, the marked development of obligations also led to a qualitative change from lax to strong obligations. In the 1980s beneﬁts were easy to access in Denmark, with hardly any strings attached, leading some Danish observers at the time to describe the unemployment beneﬁt system as a citizen wage (Langager, 1997). This description is no longer accurate. The tightening of eligibility criteria and the strengthening of obligations means that there is ‘no free lunch’ when it comes to claiming unemployment insurance beneﬁts. Conﬁguration of Fuzzy Sets into Ideal Types Esping-Andersen’s (1990) welfare state typology lives up to Weber’s deﬁnition of an ideal type as ‘formed by the one-sided accentuation of one or more points of view and by the synthesis of a great many diﬀuse, more or less present and occasionally absent concrete individual phenomena, which are arranged according to those one-sidedly emphasized viewpoints into a uniﬁed analytical construct’ (Weber, 1949: 147). Here, fuzzy-set theory is used for the study of ideal types. Although fuzzy sets and ideal types may be seen as opposites, they are not. Fuzzy-set theory

210

State generosity, social rights and obligations

can be applied to the conﬁgurational view of crucial aspects and concepts combining in ideal types (see Ragin, 2000; Kvist, 2006). Logical operations in fuzzy-set theory allow the construction and measurement of alternative types in formal and precise manners. Basically, operations with fuzzy sets are generalizations of operations on crisp sets (see Zadeh, 1965; Ragin, 2000). Suppose case x has a membership value va in fuzzy set A for , a membership value vg in fuzzy set G for , and a membership value vo in fuzzy set O for . In the presentation of the analytical property space (Lazarsfeld, 1937; Becker, 1998), the new social-democratic model of social citizenship in relation to unemployed people can be expressed in fuzzy-set terms as the ideal typical location –  * *, (A*G*O*) – or, in plain English, as a model characterized by easily accessible, generous beneﬁts with strong obligations imposed on claimants. Fuzzy set theory contains formal rules for dealing with set theoretic relationships like this one. In this case, we can make use of the intersection rule. The value of x in A*G*O is the minimum value of va, vg, and vo. This operation represents logical , denoted *, and is called the minimum principle in fuzzy-set theory. Applying the minimum principle to the membership scores in Table 9.4 suggests that the minimum value for Denmark in 1990 was 0.22. Put diﬀerently, due to lax obligation requirements Denmark was fairly out of the new social-democratic model in the early 1990s. As obligations were strengthened markedly in 1994, Denmark changed to belonging more or less (0.63) to the new social-democratic model by 1995. Due to tighter eligibility criteria making access to beneﬁts more diﬃcult in 1996, Denmark was barely a member of the new social-democratic model in 1998. Of course, cases’ membership in other models can be studied too. The old social-democratic welfare state model, for example, comprised easily accessible and generous beneﬁts that were not subject to strong obligations. Here the complement rule can be applied, i.e. that the value of x in A is 1va, where means ‘not’. This operation ﬁnds the complement to A, and is called principle of negation in fuzzy-set theory. The value of x in A*G*O is the minimum value of va, vg, and 1vo. Again, looking at the scores in Table 9.4 suggests that Denmark operated a fairly old social-democratic welfare state model, i.e. equal to a score of 0.71, in 1990. However, eight years later it was almost fully out, with a score of only 0.06 (i.e. 10.94). Behind this fundamental change in the Danish model lies a labour market reform with a series of subsequent modiﬁcations, exacerbating certain traits (such as increased obligations) uncommon to the

old social-democratic model. Combining tougher obligations with stricter accessibility (see Table 9.4) moved the Danish case into the boundary regions of the new conservative (0.47) and new social-democratic welfare state models (0.53). Finally, let us accept, for the moment, Esping-Andersen’s (1990) argument that there is only one ‘liberal’ model, i.e. that a distinction between liberal and labour is not necessary. In this case the rule of union can be applied, e.g. the value of x in AGO is the maximum value of va, vg, and vo. This operation represents the logical , denoted , and is called the maximum principle. Applied to an analysis of the liberal model, it means that the value x in (A A)*G is given by the maximum of these two expressions. In plain English, it means that the fuzzy membership score of the liberal model is the highest score of the model characterized by either not-accessible, not-generous beneﬁts or by accessible, not-generous beneﬁts. Note that the aspect of obligations is left out entirely. The view of cases as conﬁgurations of aspects introduces the idea that a single diﬀerence in an aspect between two cases may constitute a diﬀerence in kind – a qualitative distinction. Moreover, the analytical property spaces or truth tables indicate that aspects should not be viewed as independent, separable variables, but rather as elements of conﬁgurations (Ragin, 2000). Of course, in principle it remains possible that not all eight feasible combinations have empirical validity or are of theoretical relevance. However, even when some of the ideal types are empirically irrelevant, listing them helps the researcher to get an overview of the subject (see Ragin, 1987; Becker, 1998; and Ragin, 2000 for set theory ways of reducing the property space).

IDEAL TYPE ANALYSIS Table 9.5 sets out fuzzy membership scores for seven countries in the eight possible welfare state ideal types for unemployment insurance. Using these qualitative distinctions, it can be analysed which ideal type a country comes close to and its degree of membership determined. Moreover, statements can be made about which ideal type the country is furthest away from. This analysis allows nuanced judgements on the (shifting) character of national welfare states. Table 9.5 shows that Denmark and Sweden have moved from belonging to an old social-democratic unemployment insurance model to belonging to a new social-democratic model. Moreover, these were not incremental shifts. Both Sweden and Denmark moved from being fairly out of the new socialdemocratic model to becoming fairly in, and more or less in respectively. Indeed, the greater emphasis on obligations in the two Nordic countries can

be interpreted as having brought about a qualitative change in the unemployment insurance model. Furthermore, these two countries were almost fully out of many of the other ideal types during large parts of the 1990s. In other words, their unemployment insurance models are fairly distinctive most of the time. In contrast, Finland presents a more ambiguous case. Throughout the 1990s, Finland belonged to the old social-democratic ideal type, although to varying degrees. However, as the scores in Table 9.5 show, Finland is only more or less out of a number of other models. This can be interpreted as Finland having an unemployment insurance model which is less distinctive than the ones in the other two Nordic countries. The fourth Nordic country, Norway, had a fairly strong new social-democratic unemployment insurance model during the 1990s. Moreover, Norway was neither close to nor very distant from many other models. In short, the Nordic countries live up to the expectation that they operate social-democratic unemployment insurance models. However, with the exception of Finland, by the end of the 1990s they belonged to a version which could be labelled the new social-democratic model, stressing strong obligations. Due to welfare reforms, particularly in Denmark and Sweden, there has been some convergence toward the new social-democratic model in unemployment insurance across the Nordic countries. However there has been no convergence between the four Nordic and the three non-Nordic countries listed in Table 9.5. Although all seven countries intensiﬁed obligations on the part of the unemployed, the result was continued diversity, or what we have described elsewhere as ‘parallel trends, persistent diversity’ (Kautto and Kvist, 2002). The Netherlands in particular experienced a qualitative change from an old to a new conservative welfare state model. In contrast, developments in Germany and the UK have been less dramatic. Being a member of the new conservative model, Germany is not as distinct as the Netherlands, a fact which is underlined by an examination of its membership scores in other models. The scores for the UK indicate a distinctive case, i.e. that the country is fully out of both social-democratic and conservative models. In fact, the UK is situated in the border region between the labour and the liberal models. The UK seems to have stronger aﬃnities across the Atlantic than with the other European countries.

CONCLUDING REMARKS The ideal type analysis has illustrated two advantages of using fuzzy-set theory for measurement purposes. First, fuzzy sets can be constructed in order to reﬂect the ideas of theoretical concepts, thereby directly tackling

214

State generosity, social rights and obligations

the key concern of achieving measurement validity. Fuzzy-set theory demands a high degree of correspondence between concepts and fuzzy membership scores in sets established to reﬂect such concepts. Researchers must pay great attention to constructing analytical concepts, criteria for establishing qualitative breaking points, and the empirical evidence. Crucial decisions need to be made on the basis of theory, substantive knowledge and the availability and nature of data. In any case, such decisions should be suﬃciently explicit to allow for scientiﬁc dialogue and replication of the analysis. Second, it has been demonstrated how axioms in fuzzy set theory allow the interrogation of the analytical property space (i.e. the inside of the cube), and the observation of how cases move around over time. Using comparative welfare state studies for illustrative purposes has indicated how concepts such as ‘resilience’ and ‘retrenchment’ are inadequate for capturing ongoing welfare reform. Instead, often the latter could be better characterized as ‘restructuring’ due to simultaneous change in several dimensions. Using fuzzy-set theory allows qualiﬁed statements on such changes and, in the case of unemployment insurance, the identiﬁcation of a cross-country process of parallel trends but persistent diversity. In short, the chapter has aimed to illustrate how advanced fuzzy-set theory can be used for measurement purposes. If nothing else, applying the approach requires researchers to be more knowledgeable about theory and cases. In turn, such knowledge may greatly inform discussions of whether the glass is half-empty or whether it is more empty than full.

PART IV

Capturing the nature of welfare state change

10. Convergence in European welfare state analysis: convergence of what? Julia S. O’Connor INTRODUCTION Our understanding of institutional change and convergence is generally more intuitive than systematic. We think we know what we mean by convergence but in fact several alternative understandings are possible. Institutions and policies could become more alike, for instance, by becoming more like those already in existence in one country, or they could all change to some new conﬁguration. (Kitschelt et al., 1999: 438) . . . policy convergence can be deﬁned as any increase in the similarity between one or more of the characteristics of a certain policy (e.g. policy objectives, policy instruments, policy settings) across a given set of political jurisdictions over a given period of time. (Knill, 2005: 768) [Convergence is] the tendency of societies to grow more alike, to develop similarities in structures, processes and performances. (Kerr, 1983: 3)

These quotations point to two levels at which convergence is considered: institutional convergence and policy convergence. Studies of convergence often concentrate on the change in ‘performances,’ to use Kerr’s terminology, as reﬂected in structural and/or social indicators such as GDP per capita, social expenditure as a percentage of GDP or rates of unemployment but the basis on which convergence, or its absence, is asserted is often not suﬃciently speciﬁed. This includes a failure to identify clearly the dependent variable, the scope of convergence and the relevant time period over which it is measured. With a view to assessing its usefulness in comparative welfare state analysis and the apparently contradictory claims relating to convergence or its absence, this chapter addresses three issues: ﬁrst, it asks what are the essential elements of convergence, and how it might be measured. Second, it situates an examination of convergence in European Union welfare states within the context of a discussion of European integration which has the objective of political, economic and 217

218

social integration; it also focuses on Europeanization and harmonization as processes that diﬀer from, but may contribute to, convergence. Third, it examines the evidence on convergence in the European Union 15 under three headings: convergence as decreased variation in measures of welfare eﬀort, convergence through catch-up of laggards on leaders and convergence of ideas through change in the domestic frame of reference associated with the process of European integration. The chapter concludes with a discussion of the implications of the analysis for the eﬀective measurement and examination of convergence in studies of welfare states in the context of changing global pressures.

CONVERGENCE: A CONCEPT WITH MULTIPLE MEANINGS The common element in the deﬁnitions of convergence outlined above is the concept of similarity. But similarity is an ambiguous and subjective concept without clear cut-oﬀ points. Overcoming this ambiguity calls for speciﬁcation of ‘what’ is converging, the period of time over which change is measured and how it is to be measured. To this end I consider (1) societal level convergence; (2) policy convergence; and (3) measurement of convergence. Societal Level Convergence Macro-level convergence explanations are almost synonymous with the logic of industrialism view of social change originally formulated in 1960 by Kerr et al. as a response to the Marxist logic of capitalism analysis, which argued for convergence towards crisis because of the inherent contradictions of the capitalist mode of production (O’Connor, 1973). The essence of the logic of industrialism argument is that industrialization is associated with economic growth, changes in social organization, class and demographic structure and the emergence of new needs, such as a dependent population over retirement age. Social programmes are considered as a response to these needs and are facilitated by the additional resources available because of economic growth and technological change (Wilensky, 1975; 1976).1 The economic and technological determinism of the logic of industrialism and logic of capitalism approaches to social change have few proponents in the contemporary period. Yet, there is widespread acknowledgement that there are common pressures on national governments associated with globalization of trade, production and technological developments, trade openness and internationalization of ﬁnance, although the

positive and/or negative consequences of these and the ability and political commitment of national governments to resist them are debated. This resistance must take into account the role of supranational regional inﬂuences such as the European Union which may be seen as interacting with, exacerbating or ﬁltering global pressures. Whereas the earlier arguments about convergence focused on addressing the development of welfare eﬀort, as reﬂected in the percentage of GDP devoted to social welfare beneﬁts and activities, the more recent variants have focused on whether or not there has been an impact of exogenous pressures on existing welfare state eﬀort, in particular on whether a range of pressures associated with globalization have been associated with downward convergence in objectives and outcomes through retrenchment. However, at the regional level there may be diﬀerent, or at least additional, dynamics operating. The European Union identiﬁes economic and social convergence as a policy objective, for example. I consider this issue in the next section. Focusing on the global level some analysts have asked whether the exogenous pressures associated with capitalist development in the second part of the 20th century have been associated with institutional change and the convergence, or not, of all models of capitalism towards a neo-liberal model (Kitschelt et al., 1999). Based on variation in the degree to which scarce resources are controlled politically or by the market, Kitschelt et al. identify three models of the development of capitalism since the 1950s: the Liberal Market Convergence Model, the Mixed Economy Convergence Model and the Organized Capitalism Convergence Model.2 What is at issue here is not convergence or divergence but the path dependent contexts within which convergence pressures occur and their interaction with divergence pressures. The authors conclude that the three models demonstrate diﬀerent types of convergence over three periods, 1950–73 (so-called ‘Golden Age of Postwar Capitalism’), 1973–82 (‘Initial Shocks and Crises’ associated with the oil crises) and 1982 onwards (‘Transformation of Advanced Capitalist Economies’). They examine pre-existing institutional arrangements, particularly those relating to producer groups, political parties and the capacity of the bureaucracy to inﬂuence and possibly constrain the eﬀects of common exogenous challenges, and conclude that it is unlikely that there will be convergence to any unique model of capitalism. Of course this does not preclude convergence at sectoral level or on a range of dimensions. Kitschelt et al. (1999) argue for ‘a logic of “refracted divergence” in which some of the past patterns of diversity disappear, are replaced by new ones, reﬂecting institutionally mediated responses to the challenges posed by the new environment’ (ibid.: 443). In striving to balance economic growth, income inequality, political participation and government eﬀectiveness within the context of contemporary capitalism, and the associated

220

Capturing the nature of welfare state change

institutional constraints, countries respond in partially path dependent ways and path dependence is greater where institutions are more embedded. Societal convergence may encompass policy convergence that ranges from relatively minor to extensive but the absence of societal convergence does not necessarily imply the absence of policy convergence. Furthermore, an exclusive macro-level focus may obscure processes leading to policy convergence (Bennett, 1991: 217; Busch and Jorgens, 2005: 862). Analysis of policy convergence raises a wide range of questions. Do ﬁndings of convergence or its absence refer only to one aspect of a policy area or policy or the entire area or policy; one dimension of a programme, such as a regulatory programme; one aspect of social protection or the entire programme or even the orientation of the overall social policy framework? And can convergence in some programmes co-exist with divergence in other programmes? This chapter focuses largely on dimensions of policy convergence with particular focus on policy eﬀort as reﬂected in social protection expenditure processes. Policy Convergence In discussing policy convergence it is important to delineate its relationship with several other concepts which are sometimes used synonymously with it, sometimes as causal factors, and sometimes as mechanisms through which convergence is achieved. Policy transfer and policy diﬀusion are the most frequently occurring of these (Dolowitz and Marsh, 2000; Knill, 2005). Policy transfer and policy diﬀusion are processes of policy change describing how knowledge about policy characteristics is transferred or diﬀused. In contrast, convergence is the process eﬀect. Policy convergence describes ‘the end result of a process of policy change over time towards some common point regardless of the causal process’ (Knill, 2005: 768). This process may be a policy transfer or policy diﬀusion although neither necessarily results in convergence (Radaelli, 2005). These concepts are often used interchangeably and seen to result from similar causal factors although some authors emphasize the uncoordinated and voluntary nature of diﬀusion. In contrast to these processes, the dependent variable in analysis of policy convergence is the change in the diﬀerence between units, for example policy goals, content, instruments, or expenditure levels, over a period of time. Measuring Convergence Overcoming the ambiguities associated with the concept of similarity underlying convergence necessitates clear speciﬁcation not only of what is

Convergence in European welfare state analysis

221

converging but of the diﬀerent types of policy development and of the time over which change is measured. Contrary to many of the earlier studies arguing for convergence, which based their conclusions on the demonstration of diﬀerences across countries at diﬀerent levels of development at one point in time, contemporary analyses accept that convergence, as a temporal concept, must be demonstrated over time and across units. This means that ‘conclusions are drawn from the changes in diﬀerence over time’ (Seeliger, 1996: 289, emphasis in original). While the following illustrations use quantitative terminology, analysis does not have to be quantitative or use large numbers of cases; what is required is clear classiﬁcation of the dependent variable which allows transparent measurement of change. The type of policy development depends on the direction of change in the diﬀerence () between entities at time one (t1) and time two (t2). Convergence is indicated if the diﬀerence in t2 is less than the diﬀerence in time t1 ( t1 t2; divergence is indicated if the diﬀerence is greater ( t1 t2).3 These analytical categories refer to relative policy development for a deﬁned time period. The importance of specifying the time period has been demonstrated empirically in studies of welfare eﬀort; for example, O’Connor (1988) and Bouget (2003) demonstrate periods of divergence within longer periods of convergence in social expenditure in OECD countries. Furthermore, the type of policy issue, the policy dimensions and the length of their typical policy cycle are all relevant for deciding on the appropriate time frame over which convergence should be measured. The two most widely identiﬁed types of convergence are decreasing variation over time, or sigma convergence ( ), and catch-up by laggards on leaders over time, that is beta convergence (). Sigma convergence is measured using the standard deviation or coeﬃcient of variation; for example we may wish to measure the extent to which variation decreases over time in the European Union 15 or 25. Here we are talking about the variation across the entire EU 15 or 25 at diﬀerent times. This must be supplemented by examination of the patterns for individual countries – to what extent individual countries are converging or diverging; whether some countries are contributing disproportionately to the overall pattern. A necessary condition for the existence of sigma convergence is catch-up by some units or beta convergence (). But the opposite is not necessary. We could ﬁnd catch-up by some units without a decrease in the overall variation measured across the entire group. Catch-up convergence is measured by correlation or regression analysis demonstrating for example that social expenditure as a percentage of GDP at a certain time is negatively associated with its level at an earlier period and positively associated with exogenous variables inﬂuencing the growth of social expenditure. Improvement in the position

222

Capturing the nature of welfare state change

of the Cohesion Countries relative to the EU 15 level of expenditure or of the 2004 accession countries relative to EU 25 expenditure would exemplify catch-up convergence. This could be achieved by above average growth in social expenditure in the cohesion or accession countries and/or a slow down in its growth in other EU 15 or EU 25 countries. Although not widely used in welfare state analysis, mobility of units exemplifying a change in ranking over time may assist in specifying the type of change that is taking place for example within the European Union over time.4 These distinctions are important for interpreting results of convergence analysis and particularly in making comparisons across studies. Elements and Dimensions of Policy Convergence If we accept that convergence is an over time process eﬀect, we specify the time period over which it is measured and identify the type of convergence being demonstrated, we are still left with the issue of the elements of policies being compared in policy convergence research (Bennett, 1991). Some analysts argue that the focus should be conﬁned to policy output, on the grounds that the impact of intervening variables between output and outcome makes the identiﬁcation of causative links very diﬃcult in the case of outcomes (Holzinger and Knill, 2005: 776; see also Green-Pedersen, Chapter 2 in this volume). However, it is important to recognize that outcomes are increasingly the focus of convergence in the European Union reﬂected in the emphasis on Structural Indicators as an instrument to assess the progress towards meeting the Lisbon objectives (European Commission, 2006a; Eurostat, 2006b). Consequently, depending on circumstances, policy outputs, or outcomes as reﬂected in social indicators, may be the appropriate focus for the measurement of convergence. In line with this argument, policy convergence may refer to policy goals (for example, lower relative poverty rates, increased labour force participation or reduction of regional disparities in income); policy content (formal aspects such as legislation, regulations, administrative rules); policy instruments (regulatory, administrative or judicial tools); policy eﬀort or orientation (as reﬂected in level and types of expenditure), or policy outcomes (poverty rates, labour force participation rates or regional income disparities). In summary, convergence or divergence is a process eﬀect and must be demonstrated to have occurred over time and across units. It is the end result of quantitative or qualitative change in similarity or diﬀerence across units over time – these units may be societies, policies, elements of policies or expenditure. Its measurement is complex. A conclusion that convergence has occurred is indicated only if variation across units has decreased over a speciﬁed time period or if there has been catch-up by laggards on leaders

223

over time or if there has been a change in ranking over time. Speciﬁcation of the type of convergence is theoretically and empirically important in analysing and explaining the nature of the change taking place. In addition, the elements and dimensions of policy must be precisely speciﬁed if legitimate comparisons are to be made. We now turn to the issue of convergence in the EU 15 welfare states with some reference to other OECD countries.

CONVERGENCE IN EUROPEAN UNION WELFARE STATES In broad terms we can identify references to two types of convergence in the EU: on the one hand, references to upward economic and social convergence as an objective of European integration are pervasive in EU documents; on the other hand, downward convergence in the social policy area is identiﬁed as a probable negative unintended consequence of action on economic integration and more broadly as a response to the pressure of globalization forces. These facts make the EU a particularly interesting locus for analysis of convergence. Before discussing the evidence relating to types of convergence in EU welfare states it is necessary to outline what we mean by European integration and Europeanization and how they might contribute to convergence in social policy. European Integration and Europeanization European integration and Europeanization are frequently used interchangeably but they are not synonymous. In Radaelli’s words, Europeanization is ‘concerned with what happens once EU institutions are in place and produce their eﬀects’; and it is distinct from the process leading to EU policy formation – it is ‘the reverberation of that policy in national arenas’ (Radaelli, 2003: 33–4). As with globalization and convergence, Europeanization is variously deﬁned and often mistakenly used synonymously not only with European integration but with convergence and harmonization. Europeanization is not convergence – but convergence can be a consequence; it is not synonymous with harmonization – harmonization reduces diversity, Europeanization may or may not. Clearly Europeanization is a contested concept and is the subject of a voluminous literature. It is used in this chapter in the sense of change by and in Member States to meet the requirements and/or consequences of European integration. Suﬃce it to say here in relation to the European integration-Europeanization-convergence link that its examination

224

Capturing the nature of welfare state change

requires recognition of the mechanisms underlying European integration, namely, positive and negative integration (Scharpf, 1998) and framing mechanisms including the Open Method of Coordination (OMC). Positive integration refers to action taken by the Union to bring Member States’ policies and practices into conformity with a European institutional model, for example directives on environmental protection, health and safety, consumer protection and some aspects of social policy broadly conceived. Europeanization refers to the incorporation of these into the domestic framework. Negative integration refers to the removal of barriers to EU integration, for example barriers to competition to facilitate the single market. This may change the distribution of power and resources between actors in Member States. Negative integration is strengthened by European Court of Justice rulings ensuring Member State compliance with the removal of barriers to competition. These may impact on those social policy areas, such as health insurance, where a market dimension exists and where competition issues arise (Leibfried and Pierson, 2000). Privatization of other social and health areas will widen their range of inﬂuence and may constrain traditional social policy making capacity and increase pressure for convergence in strategies if not in principles. Rather than mandating particular changes, as in positive integration or altering the domestic situation to facilitate integration as in negative integration measures, framing integration alters the domestic frame of reference. Some analysts interpret this as making the domestic environment more supportive of future changes. For example, some recommendations and directives that can be transposed though relatively symbolic action may change the domestic frame of reference and the context within which future directives demanding greater change will be debated (Knill and Lehmkull, 1999). The concept of framing is used in a related but stronger and more encompassing sense by Liebert and colleagues in their studies of gender equality directives which they conclude have enhanced convergence without harmonization of EU Member States’ policy frameworks (Liebert, 2003).5 These two usages of the concept of framing indicate that it results from the working out of positive integration measures such as directives but increasingly in the social policy area it may also result from ‘facilitated coordination’ which is the term used by Bulmer and Radaelli (2005) to refer to the broad range of mechanisms of coordination where the EU institutions have relatively weak powers and where the concern is with the convergence of ideas. These include political declarations as at Council summits and/or soft law which are not legally enforceable but are directed to inﬂuencing policy practice. The OMC, which is based on soft law mechanisms such as guidelines, indicators, benchmarking and sharing of best practice and voluntary compliance, to which EU Member States have committed themselves, is an

225

increasingly important example of facilitated coordination or framing integration in the EU. This was initiated in 1997 in relation to employment and subsequently extended to other areas including poverty and social exclusion, pensions and health and social care. Already it has generated a huge literature and contradictory conclusions relating to its potential for the convergence of social policy goals and outcomes (Scharpf, 2002; Borrás and Jacobsson, 2004; Hemerijck and Berghman, 2004; O’Connor, 2005a; Zeitlin et al., 2005; Friedrich, 2006). Examination of the European integration-Europeanization-convergence link is subject to the same caveats relating to causality as any investigation of convergence with the added dimension of the European integrationEuropeanization-globalization link. Globalization is being used here to refer to the ‘transformation in the spatial organization of social relations and transactions – assessed in terms of their extensity, intensity, velocity and impact – generating transcontinental or interregional ﬂows and networks of activity, interaction and the exercise of power’ (Held et al., 1999: 16). European integration and the resulting Europeanization can be seen as defensive strategy in the context of globalization and associated neoliberalism. This is not to deny the evidence of neo-liberalism in European Union policy making (Wincott, 2003). It recognizes the fact that globalization can be seen as a threat to the European social model and that Europeanization has been identiﬁed as a ﬁlter for globalization (Wallace, 2000: 381). Yet it is important to recognize that the demonstration of causal links between globalization and/or Europeanization, on the one hand, and downward pressure on welfare services and expenditure, on the other, cannot be unambiguously demonstrated (O’Connor, 2005b). Furthermore, the relative importance not only of European integration and globalization but also of domestic political factors may vary between countries, over time and depends on the type of pressure. Convergence in the EU 15 Welfare States In this subsection we discuss convergence as decreased variation by considering how it is measured in quantitative cross-national studies of welfare eﬀort in the EU 15 and brieﬂy consider the ﬁndings of comparative case studies and studies using qualitative policy analysis. This is followed by a discussion of evidence on the changing position of the Cohesion Countries relative to the EU 15 in terms of catch-up convergence. The section concludes with a discussion of evidence on frame convergence through directives on gender equality and the Open Method of Coordination which may contribute to convergence as reﬂected in decreased variation and catch-up.

226

Capturing the nature of welfare state change

Convergence as decreased variation The convergence of social protection objectives and policies was the subject of a recommendation of the European Council in 1992 (92/442/EEC).6 It is noteworthy that this was a compromise recommendation in place of a proposal for harmonization which has consistently been resisted in the social policy area by most Member States (Chassard, 2001). Convergence in social protection was also stressed in the 1994 White Paper on Social Policy, later papers on modernizing social protection and the 2000 Social Policy Agenda (European Commission, 1994; 1997; 1999; 2000). On the basis of EU social protection expenditure data, taxes and duties as a percentage of GDP, and expenditure on active compared to passive labour market measures, Greve (1996) argued that there was evidence of social policy convergence in the European Union from 1980 to 1993. Based on evidence of relatively greater percentage increases in social protection expenditure per capita at 1985 prices by Portugal, Spain, Greece and Italy than by the mature welfare states he concluded that this was largely a consequence of catch-up convergence (Greve, 1996: 363). What does the present evidence tell us and what kind of evidence would allow us to conclude that we are witnessing convergence? Several studies provide quantitative evidence relating to the period from 1980 to the late 1990s. Cornelisse and Goudswaard (2002), Wolf (2002), Bouget (2003) and Castles (2004) all base their analysis on data from the OECD but each argues for a diﬀerent measure of social expenditure. The statistical measures of convergence used in all of the studies are relatively similar – standard deviation, coeﬃcient of variation and analysis of the contribution of particular countries to the overall variation. Wolf and Castles respectively examine the evidence for catch-up convergence through regression analysis and correlation. All recognize the importance of measuring convergence/divergence as a process that must be measured over time.7 Despite the diﬀerences in the dependent variable the ﬁndings are relatively similar in giving some support for decreased variation in welfare eﬀort in the EU 15, or the EU 15 minus one member depending on data availability, over the 1980 to 1998 period. The most detailed study of convergence in terms of its focus on EU issues is Bouget’s (2003) analysis of total public social expenditure and per capita social expenditure from 1980 to 1998 in 21 OECD countries and the EU 15 (minus Austria). He justiﬁes these dependent variables on the grounds that the possibility for substitution between social beneﬁts can be missed out when the focus is on particular social policies and the fact that macroeconomic pressure is a global one on national social expenditure. Using the standard deviation and coeﬃcient of variation, he ﬁnds convergence in the period 1980–90, divergence in 1990–93 and convergence in the

sub-period 1993–98. He explains the divergence trend between 1990 and 1993 by the international economic recession when some countries were non-sensitive (Ireland and Luxembourg) and others (Sweden and Finland) responded with dramatic increases in social expenditure. In contrast to Greve’s conclusion relating to the 1980–93 period, Bouget’s analysis does not indicate a process of catch-up in social expenditure by the Southern European countries with the exception of Greece nor does it indicate a cutback by the original more generous welfare states. Unfortunately, Greve and Bouget are using diﬀerent measures of welfare eﬀort. Greve is using EU data on social protection while Bouget is using a broader measure of social expenditure from the OECD. These deﬁnitions of social expenditure diﬀer signiﬁcantly (see De Deken and Kittel, Chapter 5, this volume).8 Bouget’s overall conclusion is that the empirical data on social expenditure do not support the thesis of convergence due to European integration. Castles (2004), who also uses the OECD Social Expenditure database but a slightly diﬀerent dependent variable to Bouget, reaches a similar conclusion relating to the absence of evidence of a European integration eﬀect. Castles excludes spending on active labour market programmes because of incomplete data in the earlier years. While ﬁnding little evidence for a distinct European Social Model based on a range of measures of welfare expenditure, he does ﬁnd evidence of convergence as measured by the coeﬃcient of variation for the OECD, Europe as a whole and the EU 15 minus Luxembourg. But he ﬁnds no evidence of ‘downward harmonization’ of social spending. Wolf (2002) reaches a similar conclusion in his analysis of the European Union from 1980 to 1997. While ﬁnding no evidence for a race to the bottom he concludes that there is ‘a more general convergence trend towards an intermediate social expenditure share’ (Wolf, 2002: 8). Cornelisse and Goudswaard (2002) analyse social security expenditure as a percentage of GDP and replacement rates for unemployment beneﬁts. Taking gross replacement rates of unemployment beneﬁts in the EU 15, excluding Luxembourg, for 1979, 1989 and 1997 they ﬁnd a consistently decreasing standard deviation and coeﬃcient of variation. When they consider social security expenditure as a percentage of GDP over the 40 year period 1960–99 for the EU 15 (excluding Luxembourg), they ﬁnd almost continuous relative convergence, as measured by the coeﬃcient of variation, but absolute convergence, as measured by the standard deviation, only in the period after 1980.9 They argue that it is too early to conclude that the convergence trends within the EU are the result of European integration, although pointing out that intensiﬁed contacts and the possibility of demonstration eﬀects of successful countries may promote convergence.

Capturing the nature of welfare state change

Considering a range of welfare state dimensions Kautto and Kvist (2002) analyse convergence in the EU 15 over the 1990 to 1997 period. Their primary focus is on trends in Nordic welfare states, Germany, the Netherlands and the UK. They argue for restructuring rather than retrenchment and while recognizing some weak evidence of convergence in some welfare state dimensions, including social protection expenditure, they conclude that Nordic welfare states illustrate ‘parallel trends’ to the other countries but ‘persistent diversity’ even in response to similar challenges. Updating their analysis of social protection expenditure as a percentage of GDP to the period from 1990 to 2003 the trend of very modest convergence in social protection expenditure is maintained (see second, third and fourth columns of Table 10.1). However, when we analyse the variation in social expenditure in Purchasing Power Standards (PPS)10 evidence of convergence is stronger (see second, third and fourth columns of Table 10.2). The signiﬁcance of PPS is that it removes the distortions due to price level diﬀerences across countries so that we are comparing equivalent purchasing power in each country. Ideally, these measures should be considered in parallel with social outcome indicators. Unfortunately this is not possible due Table 10.1

to the non-availability of a range of such indicators over a suﬃcient length of time to measure convergence. Considering, ﬁrst, social protection expenditure as a per cent of GDP we ﬁnd that the Netherlands, Ireland and Spain, the latter to a minuscule extent, are the only countries with decreased expenditure over the entire period from 1990 to 2003 (Table 10.1). It is noteworthy that the decrease in the Netherlands was in the context of expenditure that was second highest of the EU 15 in 1990 while expenditure in Ireland and Spain was among the lowest in the EU 15. Luxembourg and Sweden had decreases in expenditure in the 1990 to 2000 period. But this was not only reversed between 2000 and 2003, as it was in the other cut-back countries, it had slightly surpassed its former level in both countries by 2003 and Sweden continued to be the highest social protection spender in terms of GDP percentage. In contrast, social protection expenditure in PPS increased in all EU 15 countries between 1992 and 2003 (see column 5 of Table 10.2). The analysis of Table 10.2

the contribution of individual countries points, with some exceptions, to a process of catch-up by the initially lower spending countries and some variation in ranking particularly in the middle of the distribution. Speciﬁcally, Portugal, Greece and Ireland all increased their social protection expenditure in PPS by 84 per cent or more over the 1992 to 2003 period compared to EU 15 average and median increases of 54 and 49 per cent, respectively. In contrast, both Spain and Italy had relatively low increases of 46 and 34 per cent. Luxembourg is the exception amongst the initially higher spending countries, as measured by social protection expenditure in PPS, with an increase of 86 per cent over the period bringing its social expenditure in PPS to the top of the EU 15 countries in 2003 from a position of third highest in 1990. As noted in Table 10.2 Luxembourg is atypical due to the share of beneﬁts paid to persons living outside the country (mainly family allowances). Adjusting for this, its social expenditure in PPS is still highest in the EU 15 in 2003 (Eurostat, 2005b). More importantly, Luxembourg is also atypical because of its extreme outlier status in terms of GDP per capita. In 2003 its GDP per capita was 194 per cent of the EU average. The next highest in GDP per capita terms were Ireland at 123 and the Netherlands at 115 per cent (European Commission, 2005a). Like the quantitative studies of expenditure, recent comparative case studies of various aspects of policy give weak support for convergence in particular policy areas across two to four countries and illustrate the diﬃculties of reaching conclusions about convergence (Taylor-Gooby, 2003).11 These diﬃculties include the identiﬁcation of the aspect of policy in relation to which convergence can be demonstrated – convergence of objectives that are not operationalized and remain at the symbolic level, what Hvinden (2003) identiﬁes as ‘thin’ convergence, or convergence of operational goals and policy instruments. For example, Daguerre and Taylor-Gooby (2004) conclude that while France and the UK had relatively similar objectives in addressing challenges associated with labour market change in the 1990s, they display strong patterns of path dependency in responses and do not exhibit ‘strong tendencies to converge’. The importance of the time period over which convergence is measured has already been illustrated, for example by Bouget (2003) and in earlier studies by Castles (1982b) and O’Connor (1988) and is highlighted by Hinrichs and Kangas (2003) in their study of pension systems in Germany and Finland. They point out that change in pension systems that may eventually be characterized as a systemic change tends to occur incrementally making it diﬃcult to identify it except in the long run. The time factor also inﬂuences the appropriateness of expenditure patterns as a yardstick for assessing change: speciﬁcally, current pension expenditure is the result of past decisions, often the quite distant past, and the result of present decisions

may not be evident for many years and sometimes even decades. Jaeger and Kvist (2003) make a related point in distinguishing between ‘crises’ and challenges, which create suﬃcient pressure to demand a policy response such as welfare state restriction and/or greater eﬃciency in use of resources, and ‘controversies’, such as demographic and labour market change, whose impact is long-term, not clear-cut and can only be established empirically. These studies not only support the emphasis on identifying the appropriate time frame within which convergence should be considered, they also point to the importance of taking diﬀerent dimensions of expenditure into account in explaining over time patterns – the appropriate time frame is likely to vary across dimensions of expenditure and depending on the nature of the pressure on the welfare state. Hvinden (2003) ﬁnds no evidence for the occurrence, or likelihood, of convergence in redistributive policies relating to disability across four welfare regimes in Western Europe – the Nordic, Continental, Southern and Western, that is the liberal, ‘Social Europes’ (Ferrera, 1998) in the 1990s.12 He argues that the potential for convergence is greater in regulatory areas where there are more ‘vacant areas’ in the sense of less policy development. These are the areas in which EU action in relation to equal opportunities may be seen as more legitimated. They are also the areas in which the EU has been developing a disability strategy since the 1990s; this has been a rights based approach relating to equal opportunities, antidiscrimination and mainstreaming (CEU, 1996) that resulted in a directive establishing a general framework for equal treatment in employment and occupation in 2000 (CEU, 2000a, 2000b). This relates to the issue of convergence through framing that is discussed further on. In summary, quantitative measures of welfare eﬀort over the EU 15 provide more evidence of convergence than do qualitative studies of particular dimensions of social policy in two to four countries. Several studies using quantitative measures of welfare eﬀort as a percentage of GDP provide some evidence of decreased variation over time in the EU 15 but the strength of convergence is rather weak. When welfare eﬀort is measured by social protection expenditure in PPS there is stronger evidence not only of decreased variation but of catch-up convergence. There is no evidence of a race to the bottom in terms of welfare eﬀort in the EU 15 between 1990 and 2003 whether measured as a percentage of GDP or as social protection expenditure in PPS. We now turn to a more detailed analysis of catch-up convergence. Catch-up Convergence? Catch-up convergence is of particular relevance in the European Union in the context of the 2004 enlargement. The Structural Funds are one of the

232

Capturing the nature of welfare state change

key measures developed by the EU to address regional inequalities in income, employment, investment and growth.13 Structural Funds and national social expenditure are rarely linked in the analysis of convergence. Yet, if standard of living is the concern both dimensions of redistribution are relevant. When we examine both dimensions we ﬁnd conﬂicting patterns. Despite acknowledging the persistence of signiﬁcant disparities across the EU, the European Commission reports on economic and social cohesion provide evidence of convergence, in particular the catching up of the Objective 1 Regions in terms of GDP per capita throughout the 1989–93 and 1994–99 programme periods (European Commission, 1996; 2001a). The 2004 report points to the positive impact of structural intervention on the growth of the Cohesion Countries – Greece, Ireland, Portugal and Spain (European Commission, 2004). The catch-up, or not, of these countries since they joined the EU (or former EC) is of particular relevance in the context of the EU enlargement process. The 2004 accession countries and the applicant countries are, like the Cohesion Countries at their time of accession, considerably below the EU average in terms of GDP per capita and social development. Despite some evidence to the contrary, most academic studies of the impact of the Structural Funds support the Commission position and conclude that the allocation of regional funding to new EU members does assist the process of catch-up convergence as the additional ﬁnancial resources allow for investment in crucial infrastructure such as transportation networks. This, in turn, has an impact on the speed at which economic development progresses. A key factor in inﬂuencing this is the national policy choices and context (see McClelland and O’Connor, 2006 for a review). Delhey (2001) analyses GDP per capita, social expenditure as a percentage of GDP in the Cohesion Countries and concludes that EU membership has had largely positive implications for new Member States in the 1970 to 1997 period. In the following analysis the time period is extended to 2003, the performance of the Cohesion Countries is considered relative to the EU 1514 and social expenditure per capita in purchasing power standards (PPS) is included in the analysis. The GDP per capita in PPS of the Cohesion Countries relative to the EU 15 for selected years from 1970 to 2004 is presented in Table 10.3. With the exception of Greece, these countries have improved their position, as measured by GDP per capita, relative to the EU average between their dates of accession and 2004 although the pattern and degree of catch-up has varied considerably. Ireland has been a member of the EU since 1973 when its GDP per capita in PPS was 60 per cent of the EU 15 average. Its pattern is one of modest catch-up to the mid 1990s – its GDP per capita in PPS was only 65 per cent of the EU 15 average

in 1986 when Spain and Portugal joined the EU. From the mid 1990s catchup of GDP per capita was marked and is now second highest in the EU after Luxembourg. In contrast to Ireland, Portugal demonstrates relatively signiﬁcant catch-up in its ﬁrst 12 years of EU membership – its GDP per capita in PPS increased from 54 per cent of the EU average in 1986 to almost 74 per cent in 1999. Since then the pattern has been one of decline to 70 per cent in 2004. Spain’s catch-up in GDP per capita has been relatively steady throughout the period of its membership – from 72 to 91 per cent between 1986 and 2004. Greece as noted above is the exception to this pattern of catch-up. Its GDP per capita in PPS declined from almost 80 per cent of the EU average in 1981, when it became an EC member, to about 64 per cent in the late 1990s. By 2004 it had reached 75 per cent, which although lower than its relative position in 1981, indicates considerable progress from the late 1990s.15 While all the Cohesion Countries beneﬁted from the Structural Funds, national policy choices relating to their use, the fruition of long-term choices, for example relating to education in Ireland, and other factors such as a favourable demographic structure contributed to the outcomes. The pattern or catch-up demonstrated in GDP per capita is reversed when social expenditure as a percentage of GDP is considered from 1993 to 2003 (Table 10.4).16 Ireland and Spain demonstrated the strongest catch-up in GDP per capita but their social expenditure as a percentage of GDP and relative to the EU 15 has declined consistently since the early 1990s.

particularly evident in the case of Ireland whose social protection expenditure as a percentage of GDP was only 58 per cent of the EU average in 2003. This measure of social protection expenditure did increase signiﬁcantly in the earlier years of Ireland’s membership up to the late 1980s. In contrast to Spain and Ireland, social expenditure as a percentage of GDP in Portugal and Greece demonstrates catch-up relative to the EU 15 average between accession and 2003, when Portugal had reached 86 per cent, and Greece 93 per cent, of the EU average. At one level the relatively poor performance of Ireland and Spain is not surprising since in the context of GDP growth maintenance of the real value of social expenditure is possible despite a constant or even declining percentage of GDP. When social protection expenditure is presented in PPS per capita, all of the Cohesion Countries with the exception of Spain have improved their position relative to the EU 15 over the period from 1993 to 2003 (Table 10.4, third column for each country). The improvement is most marked for Greece which increased it PPS expenditure per capita from 45 to 67 per cent of the EU 15 average; Portugal increased its PPS expenditure from 46 to 60 per cent of the average while Ireland improved from 59 to 71 per cent. Ireland’s relative position in terms of the EU average is the best of the Cohesion Countries in 2003 but the catch-up of Portugal and Greece between the early 1990s and 2003 was considerably greater; a review of their expenditures in PPS demonstrates that Portugal more than doubled and Greece almost doubled its social protection expenditure in real terms over this period (see column 5 of Table 10.2). Despite these improvements over the 1990 to 2003 period, the Cohesion Countries in 2003 still had the lowest social expenditure in PPS in the EU 15 and while Ireland is best in PPS terms it is noteworthy that this is in the context of a signiﬁcantly higher GDP than the other Cohesion Countries and its expenditure in PPS is exceedingly low when considered relative to countries at the same level of GDP per capita. Ireland’s low social expenditure is in part due to its low old-age dependency – 17 per cent relative to an EU average of 24 per cent and an associated less than 4 per cent of GDP on old-age and survivors beneﬁts compared to almost 13 per cent for the EU 15 in 2001 (calculated from Eurostat, 2005b). However, the exclusion of this category of expenditure still leaves Irish expenditure below the EU 15 average, higher than the other Cohesion Countries and Italy but considerably lower than those countries around the average EU 15 GDP per capita (O’Connor, 2003: 393). The summary of the outcomes in terms of GDP per capita and social protection expenditure for the Cohesion Countries up to 2003 presented in Table 10.5 reinforces the conclusions of earlier studies in demonstrating that convergence has to be viewed as a long-term process that may include periods of stagnation or reversal of progress in relative terms. But it also

demonstrates that catch-up in one dimension of progress or in one measure of welfare eﬀort does not guarantee catch-up in other dimensions or measures; in particular, growth in GDP per capita relative to the EU 15 average does not guarantee a similar level of progress in social expenditure as a percentage of GDP – this is particularly evident in relation to Ireland and Spain; furthermore, divergence in one measure of welfare eﬀort – social protection as a percentage of GDP – may occur in the context of convergence in welfare eﬀort as measured by PPS as is evident for Ireland because of its increased GDP. In contrast to Ireland and Spain, both Greece and Portugal demonstrate strong catch-up relative to the EU 15 in both social protection expenditure measures since accession to the EU despite only recent modest catch-up, following earlier decline, in GDP per capita for Greece and relatively modest catch-up in GDP for Portugal since its accession. Case studies indicate progress in some areas other than income maintenance, for example gender equality provisions in Ireland (O’Connor,

237

2003) and welfare services in Spain and Greece (Guillén and Matsaganis, 2000). The situation is relation to poverty is less encouraging. Matsaganis et al. (2003) examine anti-poverty policies in Greece, Italy, Portugal and Spain and conclude that while there were signiﬁcant policy innovations in relation to poverty and social exclusion during the 1990s stimulated by EU initiatives, the safety net for people who are highly vulnerable economically continues to be frail when considered in the EU context. They point to particular constraints associated with the role of families and the relative weakness of the administrative capacity of the state in this area. In relation to Ireland, O’Connor (2003) demonstrates the persistence of high levels of relative income inequality despite improvement in ‘consistent poverty’, a measure weighted by indicators of material deprivation. Because of the short length of time over which data are available it is not possible to present a statistical assessment of the pattern of variation in poverty measures reﬂected by income after social transfer payments in the EU 15. Based on the share of persons with a disposable income below 60 per cent of the median equivalized disposable income after social transfers the evidence for the period 1999 to 2003 and 2004 indicates continuing high levels of relative poverty and social inequality in the Cohesion Countries. The evidence also indicates an overall increase in this measure of poverty in the EU 15 in 2004 at 17 per cent compared to 16 per cent in 1999, and it shows continuing diversity and the persistence of the highest levels of poverty in the EU 15 in the Cohesion Countries (Eurostat, 2006b).17 The development of Structural Indicators and the associated data together with the reporting on the National Action Plans on Poverty and Social Exclusion element of the OMC will over time enhance the possibility of examining the evidence for convergence of outcomes or its absence in this area as in others in the EU 25. In summary while we have strong evidence of catch-up as measured by GDP per capita in the Cohesion Countries relative to the EU 15, the evidence for social expenditure as a percentage of GDP presents a more mixed picture. Catch-up in this measure of social expenditure is evident only for Portugal and Greece, the countries with the weakest dynamic of economic catch-up.18 When we consider social protection in purchasing power standards we ﬁnd catch-up for these countries and for Ireland. This indicates that while the share of social protection as a percentage of GDP may decline, as in Ireland, the relative welfare eﬀort in purchasing power standards may be maintained or increased because of increased GDP. A somewhat similar pattern associated with rapidly increasing GDP is evident for Luxembourg with the signiﬁcant diﬀerence that its welfare eﬀort as percentage of GDP over the entire 1990 to 2003 period also increased. Despite catch-up convergence as measured by both measures of welfare eﬀort in

238

Greece and Portugal and in social expenditure in PPS in Ireland, the Cohesion Countries were still amongst the countries with the lowest social protection expenditure as a percentage of GDP in the EU 15 in 2003 as in 1990 and had the lowest social protection expenditure in PPS in both years. Despite the evidence of varying catch-up in expenditure patterns and progress in some other areas there is no evidence of change in the parameters of existing institutional structures – a liberal welfare regime in Ireland and adherence to the Southern model in Greece, Spain and Portugal (Guillén and Matsaganis, 2000; O’Connor, 2003) – although we may ﬁnd convergence in policy discourse and frame convergence in areas other than social protection. Convergence through Framing? The Structural Funds may contribute to catch-up convergence in particular in GDP per capita and may contribute to convergence in social expenditure but convergence in aspects of the broad social policy domain may also be the outcome of other processes in particular the related concepts of frame convergence and ‘cognitive Europeanization’. Understood as ‘the shaping and reshaping of the perceptions of, and attitudes towards, social problems and the way to tackle them’ (Radaelli, 2000), cognitive Europeanization is increasingly recognized as a signiﬁcant inﬂuence on aspects of the social policy framework, for example, welfare services in Spain, Portugal and Greece (Guillén and Palier, 2004) and gender equality in Ireland (O’Connor, 2003). Cognitive Europeanization contributes to frame convergence. We have already referred to the fact that frame convergence may be associated with the transposition of directives into national policy – an example of positive integration – and/or the broader mechanisms of facilitated coordination through political declarations as at Council summits and/or through soft law such as OMC, which is increasingly important in the broad social policy area. This form of coordination is concerned with the convergence of ideas (Bulmer and Radaelli, 2005). In both instances we are concerned with the change in the domestic frame of reference associated with the process of European integration. But this change does not necessarily imply harmonization in the sense of identity of policy output in member states nor does it necessarily imply convergence. We use harmonization to refer to a process that may but does not necessarily lead to convergence.19 Furthermore, we may identify convergence which is unrelated to EU initiatives that aim at harmonizing Member State legislation. For example, in discussing the impact of Europeanization on social and economic gender rights in six EU countries with contrasting welfare and gender regimes, Liebert (2003) argues that while EU equality

239

norms have enhanced convergence they have not produced harmonization.20 The implementation of the gender equality directives between 1975 and 2000 varied considerably depending on ‘domestic frames of mind’ but by 1998 ‘all 15 Member States had implemented the equality acquis communautaire, though without jeopardising national distinctions’ (Liebert, 2003: 13). The term ‘harmonization’ was used in the original EEC Treaty (Article 117) and has not been removed in subsequent treaties but by 1992, when the European Council made a Recommendation ‘on the convergence of social protection objectives and policies’ (92/442/EEC), it was clear that harmonization did not have the support of Member States. This is reﬂected in increasing emphasis on ‘a positive and active conception of subsidiarity’ as the key to cooperation between the European Union, Member States and citizens (European Commission, 1994: 4; Hantrais, 1995: 199–202). The processes by which EU directives are implemented by Member States vary, that is, the implementation mechanisms are not harmonized. Consistent with the primacy of subsidiarity, identical policy processes are not the objectives of convergence in the European Union – the interest is in convergence of outcomes as reﬂected in key structural and social indicators. Despite the transposition of directives on gender equality by Member States the Report on Equality between Men and Women by the European Commission (2006b) indicates that there is considerable leeway for progress and variation across member states, not only the 2004 accession countries but the EU 15, in outcomes such as the gender gap in employment, unemployment and pay rates. As Rubery puts it there are ‘many diﬀerent aspirations lying behind an apparent common commitment to pursue equal opportunities’ (Rubery, 2003: 4). Yet, while we are at the stage of convergence of ideas about key issues in gender equality rather then convergence of outcomes, we cannot assume that the latter will not occur. At a minimum the introduction of a framework of structural and social indicators will aﬀord the opportunity to assess outcomes comparatively over time, including outcomes not only in employment and unemployment disaggregated by gender but also in the gender pay gap. The OMC is a means for spreading best practice and achieving convergence towards EU goals (Bulmer and Radaelli, 2005). In so doing it is a mechanism for reconciling the potentially conﬂicting demands of economic and social policy on the one hand and Member State and EU objectives on the other (Moreno and Palier, 2004). But ideational convergence is not automatically or inevitably associated with eﬀective policy change. The monitoring of implementation of commitments made in the various National Action Plans and the assessment of progress as well as the collection of data on key structural and social indicators are important dimensions of the radical potential of the OMC. But unless they are coupled with

240

the mobilization of national stakeholders around the formulation and implementation of National Action Plans the potential will not be realized (O’Connor, 2005a).

CONCLUSIONS The concept of convergence has enjoyed varying levels of prominence in studies of welfare eﬀort and policy output but its analytical and theoretical value has been constrained by a failure to specify clearly its range of meanings and the dependent variables being examined. Convergence refers to the end result of processes of quantitative or qualitative change in similarity or diﬀerence across units over time – these units may be societies, policies, elements of policies, expenditure or outcomes. Analysis of convergence has much to contribute to the understanding of public and social policy change. To achieve this it must be part of well designed studies that specify clearly each of the following factors. What is converging and how is it to be measured: is it institutional structures or policies, if policies are we talking of policy objectives, outputs or outcomes? If policy outputs what dimension/s of policies, if outcomes what are the appropriate indicators? Is the time frame appropriate for the type of policy issue, dimension or outcome? What type of convergence is being examined – decreased variation, catch-up by laggards on leaders or change in ranking? Decisions on these questions provide guidelines on appropriate comparative frameworks for the identiﬁcation of convergence or its absence although data limitations are likely to impose constraints. A further signiﬁcant constraint in the analysis of convergence is the fact that it is widely used to refer to a process of change that is diﬃcult to delineate, namely convergence of ideas. This is evident in the general welfare state literature with reference to economic, ﬁnancial and cultural globalization and common challenges associated with demographic and labour market changes. The issue of ideational convergence is particularly evident in discussion of welfare states in the European Union in the context of European integration and the phenomena of ‘cognitive Europeanization’ and the framing of integration. Such framing alters the domestic frame of reference within which policy discussion and formulation take place and varies from the explicit transposition of EU directives into national legislation and policy to the increasingly important ‘facilitated coordination’ (Bulmer and Radaelli, 2005) through European Council declarations and soft law as reﬂected particularly in the OMC in various areas. To what extent these processes will be reﬂected in changes beyond ideational convergence, speciﬁcally, convergence in operational goals and policy instruments, is a

241

matter for systematic over time comparative analysis. More importantly the key issue is to what extent they will result in convergence of policy outcomes irrespective of the policy instruments chosen. The non-availability of social outcome indicators for a suﬃciently lengthy period of time and range of countries means that such analysis is not possible at present. It is also one of the reasons why analysts interested in the identiﬁcation of convergence or its absence across more than a few countries over an extended period of time rely on expenditure data on welfare eﬀort (but see Scruggs, Chapter 7, this volume). The potential contribution of this kind of analysis will be greatly enhanced by the over time availability of the social outcome indicators now being collected for the EU 25. European integration and Europeanization are frequently identiﬁed as the key causes of convergence towards the top or the bottom in terms of social policy standards in the European Union. It has been argued in this chapter that a hypothesized Europeanization-convergence link must be unpacked to take into account the mechanism underlying European integration – positive integration, negative integration or framing integration through positive integration as in directives or facilitated coordination as in the open method of coordination. None of these mechanisms operates in a vacuum – their operation is facilitated and constrained by a range of policy and country speciﬁc factors. Most importantly, they are constrained by domestic political factors and policy choices. This emphasis on the importance of political and institutional factors echoes the challenges to the logic of industrialism and logic of capitalism arguments of the 1960s and 1970s relating to the welfare state. Those studies emphasized the importance of political and institutional factors in explaining persisting diﬀerences and in some instances growing diversity across welfare states. Similarly, those studies that directly addressed the issue of convergence or divergence and found evidence of convergence in relation to particular measure of welfare eﬀort over particular periods, and its absence in other time periods and in other measures of welfare eﬀort, stressed the signiﬁcance of political and institutional variables (Castles, 1982b; Uusitalo, 1984; O’Connor, 1988; Montanari, 2001 re social rights). In this analysis we have concentrated on the European Union 15 and identiﬁed the possible inﬂuence of various dimensions of European integration. This is an incomplete exercise: the European integrationEuropeanization-convergence linkage must also include the overarching inﬂuence of globalization of economic and ﬁnancial ﬂows – as was pointed out, Europeanization may be seen as a conduit or ﬁlter for globalization inﬂuences on Member States. Furthermore, inﬂuence on policy frames is not conﬁned to the European Union – the inﬂuence of the OECD for example in its economic reports (Armingeon, 2004) and probably more strongly in

242

relation to activation is likely to have inﬂuenced the employment policy frame in most EU countries and in addition was ﬁltered through EU policy. Work on convergence stems from sources with diverse theoretical, ideological and disciplinary backgrounds. While this has been associated to date with diﬀerent parallel streams of analysis, cross-fertilization could contribute to a vibrant research agenda. Such a development is not only essential for eﬀective analysis of convergence but is particularly appropriate in this area that brings into consideration the impact of globalization, European integration and Europeanization on contemporary public and social policy.

The ﬁndings and methodological approach of these studies were challenged by studies starting from a focus on the explanation of diversity in welfare state development amongst countries at a broadly similar level of development that demonstrated the importance of class mobilization in trade unions and political parties (Korpi, 1983; Stephens, 1979). Since both sets of studies were cross-sectional they demonstrated diﬀerence not convergence or divergence (Castles, 1982a). Later studies did consider the issue of change over time and demonstrated the importance of the time period over which convergence was measured and the indicator of the welfare state used. Convergence was evident only in relation to social transfer payments aspects of social expenditure (see O’Connor, 1988 for a review). Political control aggregates direct state control of the economy, as reﬂected in state ownership and the extent to which factors other than proﬁtability inﬂuence decisions; indirect state control as reﬂected in subsidies, taxes and regulations; welfare state interventions and labour market organization. Seeliger (1996: 289–96) uses synchronous development to describe identical diﬀerences between units at both times. This is identiﬁed by Heichel, Pape and Sommerer (2005) as gamma-convergence ( ). They also identify delta-convergence () to describe the minimizing of distance from an exemplary model, for example, as promoted by an international organization. Liebert and colleagues deﬁne Europeanization as ‘transnational processes conducive to shared frameworks, such that, as Helen Wallace puts it, “a European dimension becomes an embedded feature which frames politics and policy within the European states” ’ (Wallace, 2000: 370) (Liebert, 2003: 14). In the same year the Council passed recommendation 92/441/EEC concerning suﬃcient resources for social protection in social protection systems. Many of the studies in the 1970s purporting to demonstrate convergence were crosssectional, based on countries at vastly diﬀerent levels of economic development (Cutright, 1967; Miller, 1976; Wilensky, 1975). The components of social expenditure included in the OECD measure are public and private mandatory programmes of cash beneﬁts for old age, disability and family; sickness and survivors’ beneﬁts; unemployment; public expenditure on health; housing; family services; services for elderly and disabled people; occupational injury and disease; active labour market programmes; and other contingencies. Social protection in the European Union includes the following beneﬁts: old-age and survivors’; sickness/health care; disability; family; unemployment; housing and social exclusion. In contrast, the non-EU countries considered – Norway, Switzerland, the United States, Japan and Australia – demonstrate consistent divergence as reﬂected in increasing standard deviations since 1980. This conﬂicts with Castles’ (2004) conclusions, in which

he identiﬁes the convergence of a Northern European grouping composed of the Scandinavian and continental Western European countries, all members of the European Union (Austria, France, Germany, the Netherlands and Belgium) but also Switzerland (Castles, 2004: 80). As pointed out above the measures of welfare eﬀort used by Cornelisse and Goudswaard and Castles are very diﬀerent (see note 8). Purchasing Power Standards refer to an independent unit of any national currency that removes the distortions due to price level diﬀerences. The PPS values are derived by using Purchasing Power Parities (PPPs) as a weighted average of relative price ratios in respect of a homogeneous basket of goods and services, comparable and representative for each Member State (Eurostat, 2005a). Social Policy and Administration 37(6) in 2003 brings together several studies. The division is based on four characteristics of the countries’ social protection systems: eligibility, beneﬁt formulae, ﬁnancing regulations and organizational-managerial relations (Hvinden, 2003: 613). Article 158 of the Consolidated Version of the Treaty Establishing the European Community outlines its economic and social cohesion provisions in terms of promoting overall ‘harmonious development’ to be achieved by ‘reducing disparities between the levels of development of the various regions and the backwardness of the least favoured regions or islands, including rural areas’. According to the European Commission the reduction of disparities in their geographical dimension is taken to mean ‘convergence of basic incomes through GDP growth, of competitiveness and of employment’ (European Commission, 1996: 13–14). Delhey (2001) situates social expenditure relative to the EU 12, that is the EU 15 without Austria, Finland and Sweden in the 1970 to 1997 period and GDP relative to the EU 15 up to 1998. Delhey (2001: 222) argues that the Greek experience of EU membership reﬂects the economic risks of premature accession. The year 1993 is the ﬁrst year for which ﬁgures relative to the EU 15100 are available. http://epp.eurostat.cec.eu.int/portal/page?_pageid1996,45323734&_dadportal&_ schemaPORTAL&screenwelcomeref&open/&productSTRIND_SOCOHE& depth2. This provides the social cohesion tables that are part of the broader Structural Indicators series. Signiﬁcant catch-up in social expenditure is not always associated with lower GDP. Focusing on 21 OECD countries between 1980 and 1998, Castles (2004: 25) found the highest increase in total public social expenditure based on OECD data in Switzerland, a country with high GDP per capita. Its increase was 13 per cent; Greece was next highest with 11 per cent, then Sweden and Norway with 8 per cent and Portugal with a 7 per cent increase. The overall mean increase was 4 per cent. Harmonization is sometimes used synonymously with convergence, for example, Castles (2004: 74–5) speaks of upward and downward harmonization in the same vein as upward and downward convergence of social protection. The countries studied are France, Germany, Italy, the UK, Spain and Sweden.

11. (In)Dependence as dependent variable: conceptualizing and measuring ‘de-familization’ Sigrid Leitner and Stephan Lessenich INTRODUCTION Looking at the current wave of social policy reform in Western Europe, it might seem as if these were pretty good times for the ‘women-friendly welfare state’ feminist politics and research have been striving for over the last two decades or so. In the context of a broad reform process framed almost everywhere throughout the EU (15) in terms of ‘employability’ and ‘activation’, the advancement of female labour market participation ranks high – if not ﬁrst – on the political agenda of social policy makers. Women’s well-being (or ‘well-fare’), understood as their belated labour market individualization, stands at the centre of a new, postindustrial welfare equilibrium. As Gøsta Esping-Andersen (2002a: 3), the spiritus rector of European welfare state restructuring, puts it, ‘[i]deological predilections aside, it should be evident to all that we cannot aﬀord not to be egalitarians in the advanced economies of the twenty-ﬁrst century,’ and gender equality, at least as far as access to the labour market is concerned, is absolutely central to the agenda of the new egalitarianism. In order to free women from family care responsibilities and to enable their labour market participation, the ‘de-familization’ of welfare production has been established as the golden rule of welfare reform. The locus classicus of the mainstream understanding of ‘de-familization’ (or, as he puts it, ‘de-familialization’) is Esping-Andersen’s The Social Foundations of Post-Industrial Economies (1999: 45–6, 50–1). The simple formula to be found there, equating ‘an active policy committed to lessening the caring burdens of the family’ (1999: 45) with (a) the promotion of labour market participation and (b) the enhancement of economic independence of (c) women, has become common wisdom in scientiﬁc and political discourses alike. In line with Esping-Andersen’s deﬁnition, ‘de-familization’ is unequivocally used to denote ‘policies . . . that maximize individuals’ command of 244

Conceptualizing and measuring ‘de-familization’

245

economic resources independently of familial or conjugal reciprocities’ (1999: 45) – ‘individuals’ always and evidently meaning ‘females’: ‘Hence, defamilialization would indicate the degree to which social policy (or perhaps markets) render women autonomous to become “commodiﬁed”, or to set up independent households, in the ﬁrst place’ (1999: 51). It comes as no surprise, then, that Esping-Andersen’s widely shared vision of ‘a Viable New European Welfare Architecture’ (2002a: 5) is centered around ‘defamilization’ – even if the term does not ﬁgure explicitly in his policy outline written for the Belgian Presidency of the European Union. To put it in a nutshell, Esping-Andersen’s recommendation to policy makers in postindustrial Europe (2002a, b, c) is to do it the Nordic way (minus labour market segregation by sex), i.e. to stick to a combined policy strategy focused on child welfare and gender equality, the links of which ‘all boil down to women’s employment’ (2002c: 67). The ‘basic “women-friendly” policy package’ (2002c: 73) propagated by Esping-Andersen thus includes measures to counteract the crisis of the industrial male breadwinner by way of ‘female life course masculinization’ (2002c: 95), i.e.: de-familization. According to the author, this strategy represents a substantial positive-sum game, reconciling in a virtuous circle family welfare (in terms of reduced child poverty and enhanced psychological well-being of children) and ‘the common good’ (meaning, above all, rising fertility rates and increased educational standards) with women’s liberation from family responsibilities and economic dependence. In the year 2000, the European Council acted in line with this argumentation when recommending to raise female employment rates in all member countries from the then average of 51 per cent to over 60 per cent by 2010. In 2002, the European Commission as well as the European Council even extended the European Employment Strategy and formulated targets for the expansion of child care facilities: by 2010 ‘[c]hild care should be available to at least 90 per cent of children between three years old and the mandatory school age and to at least 33 per cent of children under three years of age’ (CEC, 2002: 20). The so-called ‘adult worker model’ (Lewis, 2001) builds the new foundation for economic and social policies promoted by the European Union, and recent legislation in many European countries makes an attempt to comply with the EU targets. Even in the hitherto highly ‘familialistic’, conservative welfare regimes of continental Europe the welfare state has been reinvented as an ‘independent variable’ for female independence. Or so it may seem, at ﬁrst glance. In what follows, we will challenge the notion of ‘de-familization’ and its equation with female independence so common in both feminist and main(male)stream welfare state analysis. It will be shown that the concept of ‘de-familization’ has to be deconstructed analytically in order to account for its – at a second glance – highly ambivalent eﬀects on the choices and economic self-reliance of women.

RECONSTRUCTING ‘DE-FAMILIZATION’: BETWEEN DEPENDENCY AND INDEPENDENCE In this section we will embed the concept of de-familization within the feminist tradition of welfare state research. It will be shown that women’s care work provided within the family was identiﬁed as one of the main sources of the gender division in modern social policy. As a consequence, feminists called for the de-familization of women through the expansion of public care services for children and older people. But the shifting of caring responsibilities from the family to the welfare state is only one way to alter women’s dependency status. We will, in the ﬁrst step of our argument, highlight the remaining pieces of the picture of female economic independence. Early feminist research strongly distrusted the welfare state as such which was conceived as a male dominated system that reinforces patriarchy. The focus of analysis was on the ways in which social policies worked in order to suppress women and to uphold male dominance (Riedmüller, 1984; Abramovitz, 1988; Gerhard et al., 1988; Pateman, 1989). As a result, the welfare state was often rejected as a whole – at least by radical feminists. Another branch of feminist work asserted a shift from private to public patriarchy (Hernes, 1984): the emergence and expansion of the welfare state decreased women’s economic dependence from individual men but – at the same time – established a new form of female dependence with regard to the welfare state and its institutions. Since women were under-represented in the political arena of parties, parliaments and corporatist decision making, they had little power over the structures of the welfare system. Thus, women were clients, consumers and employees of the welfare state but not fully integrated citizens. Men were the agents and women the objects within the political system (Siim, 1987). Nevertheless, the social rights provided by the welfare state were seen to hold an emancipatory potential for women. The transformation from private to public dependence has not only improved women’s economic independence from the male breadwinner but also provides new resources for mobilization, protest and political inﬂuence (Fox Piven, 1984; Dahlerup, 1987). While this early feminist work concentrated on ‘the welfare state’ as a macrostructure (or even ‘superstructure’) of patriarchal domination, further research tried to identify and analyse more speciﬁcally the arrangements and mechanisms making for the gendered character of social rights in the context of diﬀering national histories of welfare state development. In general, feminist research identiﬁed two dimensions of gender discrimination in the welfare state (cf. Orloﬀ, 1993: 315). On the one hand, welfare states distinguish between employment (or wage labour) and unpaid labour. Whereas employment is covered by contributory social security

Conceptualizing and measuring ‘de-familization’

247

systems that predominantly beneﬁt men, unpaid labour’s social rights are bound to social assistance programmes that serve a predominantly female clientele. This ‘two-tier’ system (Nelson, 1984) prolongs the inferior status of women. Their unpaid labour does not generate equal social rights since social assistance programmes are mostly means tested and subject to social control of the clients while social insurance beneﬁts are received as earned rights due to contribution payments.1 On the other hand, the welfare state treats women as dependants by granting derived social rights for married women. This incorporation of women on the basis of their husbands’ contributions to the social security system institutionalizes and reproduces women’s dependency on the male breadwinner, which makes them especially vulnerable in cases of divorce (Lewis, 1992). The familization of women, i.e. their dominant role in the provision of care, was identiﬁed as the main hindrance to women’s labour market participation. According to feminist accounts, their way to economic independence was blocked due to the division of care work between women and the state2 as well as between women and men. Moreover, the welfare state refused to reward paid and unpaid work equally. The inferior treatment of women’s unpaid care work kept them in a status of economic dependency. They were either clients of stigmatizing social assistance programmes or dependent on a breadwinner. From these feminist deﬁcit analyses emerged demands for a women-friendly welfare state that would promote the independence of women. We will shortly discuss the most prominent proposals for a women-friendly welfare state in what follows. Ann Orloﬀ (1993: 319–22) claimed that welfare states should provide women with the capacity to form and maintain an autonomous household. According to her, this could be achieved by two diﬀerent strategies: (1) providing payments for family care that secure economic independence of the carer and her dependants or (2) improving women’s access to paid work and unburdening the family from care work through the expansion of public services.3 There is an obvious tension between the two strategies, but they could also be combined. Although Orloﬀ is holding up both options, she seems to have a preference for the second strategy, arguing that the history of payments for care shows that the beneﬁts provided were usually very low and not comparable to wage earners’ beneﬁts. Taking a historical stance she claims that, recurring conﬂicts of interest among women notwithstanding, most postwar women’s movements promoted women’s labour market participation instead of a ‘mothers’ (or carers’) wage’. Since the political decision for one or the other of these strategies should democratically reﬂect women’s real interests, history suggests – according to Orloﬀ – a normative preference for the second strategy which feminist welfare state theory cannot ignore. In a later article, Orloﬀ (1997) distinguishes between contemporary women’s

248

Capturing the nature of welfare state change

movements in the liberal countries and in Scandinavia that pursue women’s access to employment, and women’s movements in some continental European countries and the historical women’s movements that are (were) in favour of payments for care. Orloﬀ argues that women might well have diﬀerent ‘contextualised interests’, but that there still is the overall goal of ‘emancipation’ operating as a common strategic gender interest throughout diﬀerent political contexts. Since the emancipatory eﬀects of payments for care are disputed, access to employment seems to be the more legitimate strategy – and the more so in times of ﬁscal austerity and budget cuts that render the guarantee of real ‘choice’ an unrealistic policy option.4 In her postindustrial thought experiment, Nancy Fraser (1997: 42–65) examines the two strategies which she calls the Caregiver Parity model and the Universal Breadwinner model. Whereas the ﬁrst focuses on state provision of care giver allowances, the second relies on employment enabling services. Fraser concludes that both (ideal) models are good at preventing women’s poverty and exploitation. As far as it goes, each of them would contribute to the independence of women. However, Fraser goes beyond the notion of independence. She develops ﬁve additional criteria which have to be met in order to achieve true gender equity: income equality, leisure-time equality, equality of respect, anti-marginalization and antiandrocentrism. Only in a Universal Caregiver model can all of these criteria be met. This would imply that all, women and men, combine breadwinning and care giving and that the institutions of employment and care are redesigned in a way that systematically allows for this combination. Working hours would have to be reduced and employment enabling services would be available for everybody. Informal care work would be publicly supported and would be provided inside and outside households by relatives, friends and ‘civil society’ at large. Also, people without kin based responsibilities would have to provide care. Another approach that radicalizes the focus on care (and payments for care) as a fundamental element of social citizenship is the one elaborated by Trudie Knijn and Monique Kremer (1997). Within their concept of inclusive citizenship, paid work and care are of equal importance since every citizen will – at least once in his or her life – either provide care or be in need of care. Knijn and Kremer systematically distinguish between the right to time for care and the right to receive care. Whereas the ﬁrst enables informal care giving – without enforcing it – by direct ﬁnancial compensation of care, the second guarantees access to qualitatively good professional provision of care. Quite interestingly for our context, Knijn and Kremer do not give normative priority to the ‘independence’ of citizens but rather stress their mutual (inter)dependence and the reciprocity of care and ‘care giving’, which for them is not only a matter of giving help, but also of

Conceptualizing and measuring ‘de-familization’

249

receiving (immaterial, emotional etc.) rewards. Their claim is to recognize the central importance of care giving and care receiving in the context of not (only) the political economy, but the sociology (i.e. the social order) of the welfare state. It should be clear from this review of selected (and exemplary) feminist visions of a women-friendly welfare state that ‘de-familization’ understood (as is most generally done) as the unburdening of ‘the family’ (read: women) from care responsibilities represents only one dimension within an allencompassing feminist agenda for restructuring the gendered welfare state. The individualization of social rights is just as much on this agenda as the ﬁnancial compensation of family care and the redistribution of care work from women to men within and beyond the family. Thus, it seems only fair at this point to stress that, according to feminist theorizing on the welfare state, access to paid labour or, more speciﬁcally, to public services enabling and facilitating women’s labour market participation is not the one and only way to women’s independence and to gender equality in the welfare state.

DECONSTRUCTING ‘DE-FAMILIZATION’ AND ‘INDEPENDENCE’ Having said (and shown) this, we will now try to adapt the ‘mainstream’ conceptualization of ‘de-familization’ to the whole of theoretical knowledge as developed by feminist welfare state research. In the next step of our argument we will make plausible that on a conceptual level – and contrary to what policy makers and their political consultants across Europe are telling us and trying to make us believe – de-familization (a) is not automatically and unequivocally increasing the ‘independence’ of women (or men), that de-familization (b) includes not only an economic but also a social dimension, and that de-familization (c) comprises not only the care giver’s but also the care receiver’s perspective. Things are more complicated than they seem at ﬁrst glance – and than mainstream concepts of ‘defamilization’ would like to have them. De-familization is a complex, multifaceted concept. At its core is the question of ‘who cares’. De-familization was ﬁrst deﬁned by Eithne McLaughlin and Caroline Glendinning (1994: 65) as follows: . . . de-familisation is constituted by those provisions and practices which vary the extent to which well-being is dependent on ‘our’ relation to the (patriarchal) family. . . . de-familisation is about the terms and conditions under which people engage in families, and the extent to which they can uphold an acceptable standard of living independently of (patriarchal) ‘family’ participation.

Thus, de-familization refers to the question of (in)dependence within familial care relationships. Since a care relationship comprises the care giver on the one side and the care receiver on the other, de-familization cannot be reduced analytically to the situation of the care giver. De-familization processes change the care relationship as a whole and therefore also have an impact on the care receiver. The ﬁrst part of the quote given above allows us to think of de-familization in this double perspective: on the one hand, de-familization has to be judged from the perspective of persons receiving care. We must ask for their status of dependence on or independence from the family, i.e. care receivers might be dependent on care given by a member of their own family (or household) or on ﬁnancial support by the family in order to meet care needs. Care receivers might also be given a right to receive care as suggested by Knijn and Kremer (1997) who refer to a guaranteed access to qualitatively good professional care.5 On the other hand, de-familization has to be judged from the perspective of care givers. We must ask for their dependence on or independence from other members of their family or household. They might be dependent on ﬁnancial support by the family breadwinner in order to meet care obligations or they might be bound by the expectations of care receivers that their needs should be met by close family members. Thus, the status of the care giver might be strengthened by a right to care which enables and rewards care giving through ﬁnancial compensation as well as by a right not to care (cf. Lewis, 1997) which allows the care giver to leave a care relationship, e.g. because professional care takes over care obligations.6 Drawing from this clariﬁcation of diﬀerent perspectives of (in)dependence we argue that the dependency or independence of both care receivers and care givers falls into two analytical dimensions: the degree of social (de-)familization, on the one hand, and of economic (de-)familization, on the other. In what follows, we will elaborate further these two dimensions with regard to care relationships between parents and children.7 The social dimension of (de-)familization is about the social and emotional relationship between the care giver (parent) and the care receiver (child). Usually, the parent feels an obligation to care for the child while the child is young and heavily emotionally bound to the parent.8 From the parent’s perspective, however, social de-familization would mean the right not to care for his or her child. Although we do not assume that parents could (or even should) be completely de-familized in this sense, they might nevertheless be de-familized gradually. On the one hand, the provision of child care services will contribute to the social de-familization of the parent, especially if they are low-cost, high-quality and easily available. On the other hand, the parent can become socially de-familized if other persons of the family or household take over (part of the) child care. Most obviously,

this could be the case within a model of shared parenthood with both parents accepting care responsibilities or within an intergenerational care arrangement with the grandparents providing care for their grandchildren.9 It should be acknowledged, however, that the social de-familization of the parent enables him or her to follow other interests besides child care. Labour market participation could be – but does not automatically have to be – such an interest. From the child’s perspective, social de-familization means the right not to be cared for by the (i.e. one) parent exclusively. Children have a need for additional care relationships with other family members (e.g. the other parent or the grandparents) and also with other persons from outside the family or household in order to fully develop their cognitive, intellectual and emotional potentials. The child’s right to both parents and its access to child care services outside the family’s household is thus central for the child’s degree of social de-familization. It is of course an open question (to be answered diﬀerently in diﬀerent cases and contexts) what degree of social de-familization ﬁts a child’s need. An intercessor or ‘child advocate’ could strengthen the position of the child within the care relationship and make sure that the child’s needs are assessed and met.10 The economic dimension of (de-)familization (to be distinguished from the social relationship conceptualized so far) describes diﬀerent variants of choice for the care giver and the care receiver. From the perspective of the care giver (parent) the decision to what extent the child will be cared for by him or her depends also – and not least – on the ﬁnancial possibilities (or restrictions) of the parent. A situation in which the parent is ﬁnancially dependent on other members of his/her family or household might enable the parent economically to care just as well as if the parent receives direct payments for child care. But only ﬁnancial independence of the parent gives him/her a substantial right to care and thus provides what could be called a ‘real choice’. The economic de-familization of the parent therefore requires his or her ﬁnancial independence which would be best granted by payments for child care that allow the parent to form and maintain an autonomous household (cf. Orloﬀ, 1993). An eﬀective right to care is guaranteed only by direct and individualized payments for care.11 From an analytical perspective focusing on the child’s (or the care receiver’s) well-being, economic (de-)familization concentrates on the question of who covers the costs of the child’s care needs. Children have a right to choose additional care relationships besides their relations to close family members. These will standardly be care services or educational services which will have to be paid for. The costs of the child’s right to choose such services could be borne either by the family (or household) or by the welfare state. But, to be sure, only a socialization of these costs through

252

public transfer payments can, from the child’s perspective, guarantee ‘real choice’ and the economic de-familization of the child. When seen against the backdrop of this thorough analytical ‘deconstruction’ of the concept, the restrictions and shortcomings of the mainstream debate on de-familization should become immediately obvious. The common use of the concept distorts, and in a sense ‘de-problematizes’, the real-world processes and constellations of a ‘de-familization’ of care. We can distinguish two main aspects with regard to the inadequacy and undercomplexity of mainstream conceptualizations. First and most fundamentally, when talking of the need to de-familize care, the talk usually refers to the care giver only, disregarding the person in need of care and the consequences that de-familization may entail for him or her. (If the situation of the needy part of the care relationship is taken into account at all, it is commonly presupposed that the act of de-familization has unambiguously positive eﬀects on the well-being of those receiving care.) Correspondingly, the independence the care giver is meant to enjoy through de-familization is strictly deﬁned in the sense of ﬁnancial independence, basically ignoring the social and emotional aspects of the care giver’s ‘liberation’ from his or her care responsibilities. (Again, where such considerations are given at all, there is no discussion of possible trade-oﬀs between both dimensions because it is generally assumed that the social and/or emotional independence of the care giver with regard to the person in need of care is a value in itself.) Thus, what we are currently facing in the political as well as in the scientiﬁc debate on ‘de-familization’ is a signiﬁcant conceptual reductionism (Table 11.1).12 Building on this reductionism, the next simpliﬁcation characterizing current debates is that de-familizing the care giver (understood unidimensionally as the unburdening of the parent from care responsibilities, i.e. our dimension of social de-familization) is supposed to lead quasiautomatically to his or her economic independence, while the familization of care work (understood correspondingly as the burdening of the parent with care responsibilities, i.e. our dimension of social familization) is systematically equated with the economic dependency of the care giver – the care giver, almost needless to say, explicitly or implicitly being supposed to be the child’s mother and not the father. In other words: mainstream theorizing on and politicizing for ‘de-familization’ is characterized not only by Table 11.1

an exclusive focus on care givers, on the social (de-)familization of care givers and on the economic (in)dependence (via labour market participation) of care givers – read: women – but also by a remarkably low tolerance for ambiguity, i.e. for the ambivalences and trade-oﬀs the road to ‘defamilization’ (or, more exactly, to this variety of de-familization) might be paved with. Even if we, as a ﬁrst step, accept part of the reductionism of mainstream conceptualizations and concentrate on the perspective of the care givers, there still remain counterintuitive interrelations between the two dimensions of social and economic (de-)familization and the (in)dependence of care givers. These amours dangereux for the dominant de-familization discourse, which commonly remain unacknowledged, may be systematized as shown in Table 11.2. Stating our argument in the most general terms, it is important to understand that there is no given, predetermined correlation between ‘(de-) familization’ of care (in its diﬀerent facets) and the economic or social independence of women as care givers (always supposing that the ‘normal’ care giver is female, which is (a) empirically true and (b) politically assumed). The four ‘intuitive’ (‘i’) and ‘counter-intuitive’ (‘c’) cases derived from Table 11.2 will be explained in the following by referring again to care relationships between parent and child: (1) (i) If parents are socially familized as care givers, because there is no possibility to share child care either within the family nor by using child care Table 11.2 Intuitive and counterintuitive relations between social/economic (de-)familization and economic/social (in)dependence from the care giver’s perspective If . . .

facilities, the intuition would be (and actually is) to count them as ﬁnancially dependent. Given that they are not willing to neglect their children, no options to gain ﬁnancial independence via labour market participation are available for socially familized parents. (c) But: Even if the parent is the only provider of child care so that he or she is totally socially familized, the parent might be (at least partially) economically independent, e.g. due to individualized payments for care like paid parental leave. The degree of the parent’s independence would then be determined by the character (most importantly: the amount) of the payments for care, which allow the parent to develop (at least to a certain degree) economic independence from other household members and their earned incomes. However, payments for care might be (a) very low in terms of the amount and/or the duration of the beneﬁt or (b) not fully individualized, e.g. if the amount of the beneﬁt depends on the household income. In these cases (and especially if both (a) and (b) apply) the economic independence of the carer from his or her family will not be extended suﬃciently. The most widespread individualized payment for child care is paid parental leave. Interestingly, countries which provide poor rates of formal child care (for children under three years old) and thus aim at the social familization of parents tend to have (if at all) also poor individualized beneﬁts for child care. Their parental leave beneﬁts are mostly low ﬂat-rate payments which do not allow for the ﬁnancial independence of the parent, e.g. the monthly ﬂat rate amounts to €436 in Austria and – depending on the household income and the duration of the leave – to a maximum of €300 or €450 in Germany. In Italy, the beneﬁt amounts to 30 per cent of the former wage and lasts only for six months whereas Germany provides payments for a maximum of two years and Austria even for a maximum of three years (cf. Leitner, 2003: 371). Thus, there is little empirical evidence for our argument, but the example of Luxembourg shows that high social familization of parents might indeed go hand in hand with high ﬁnancial independence: Since 1999, parents can take six months of full-time leave from employment with a monthly beneﬁt of €1,693 attached to it or 12 months of half-time leave with a monthly beneﬁt of €846 (SSA, 2004). Moreover, the most recent German proposal to reform parental leave beneﬁts aims at introducing a beneﬁt based on 67 per cent of the parent’s former wage. Starting from 2007, the so called Elterngeld is supposed to be paid for ten months and can be extended to 14 months if the other parent takes at least two months of the leave. Besides individualized payments for care, socially familized parents can be thought of being economically independent due to contingent reasons (personal wealth or the existence of other income ﬂows) or because of – and this is an important point to keep in mind with regard to possible social

policy reforms in the future – a welfare state systematically geared towards guaranteeing a basic income to every citizen. (We will be coming back to this last argument in the concluding part of the chapter.) (2) (i) If parents are socially de-familized – either due to the availability of child care facilities or because other family members share care responsibilities – they are supposed to be enabled to gain income via employment and thus (may) become economically independent. This is EspingAndersen’s (and the de-familization mainstream’s) line of argumentation described in the introduction to this chapter. We should nevertheless not forget to point out that there are also countries with high rates of formal child care (even for very young children) which provide comparatively high individualized payments for child care and thus contribute to the ﬁnancial independence of parents: e.g. in Sweden the parental leave beneﬁt amounts to 75 per cent of former earnings and the Danish ﬂat rate during parental leave is rather high (cf. Leitner, 2003: 371).13 (c) But: We should be aware of the fact that the social de-familization of the parent does not necessarily increase his or her economic independence. In spite of the new opportunity structure (in terms of mothers’ labour market participation) brought about by the social de-familization of child care, the former care giver might not succeed in the labour market and earn only insuﬃcient incomes to make him/her (or his/her household) truly ‘independent’. Many employed mothers are still ﬁnancially dependent on their husband’s income or on welfare payments. In a situation of high unemployment, the chances for mothers to (re-) enter the labour market are a priori restricted. In fact, women’s increased employment rates tend to be based on more ‘ﬂexible’ jobs with low job security and low wages (Lewis and Giullari, 2005: 82). Those who are employed are often working part-time to reconcile work and family life. Although women, in general, have high part-time rates, mothers’ incidence of part-time work is even higher, especially if there are two or more children. The Netherlands has the highest rate of part-time workers among mothers: 80 per cent of mothers with two or more children work part-time. In Australia, Germany, Switzerland and the United Kingdom, the share amounts to more than 60 per cent. Like women in general, working mothers earn, on average, 16 per cent less than men per hour worked. Besides direct wage discrimination, this gender wage gap accounts for the occupational and sectoral as well as the vertical segregation of employment by gender. Due to shorter working hours and the gender wage gap, there is also a considerable monthly wage gap between men and women. In the Netherlands and the United Kingdom, the monthly gender wage gap is highest with women earning just over half of what men earn. But

256

Capturing the nature of welfare state change

even in Sweden, one of Esping-Andersen’s best-practice countries, women earn only 70 per cent of men’s monthly income (cf. OECD, 2002). Thus, the achievement of economic independence through labour market participation is at least dubious for mothers. Their chances seem to rest more on a gradual economic autonomy. Moreover, despite the fact that the availability of child care, i.e. the social de-familization of the parent, is one of the most important prerequisites for mothers’ employment, the sound reconciliation of work and child care requires more than the availability of child care services. Flexible time structures would be needed for both child care and working hours to make ends meet. After all, at least part of the constraint on mothers’ employment is the low availability of part-time employment. This is especially important for Greece, Ireland, Italy, Luxembourg, and Spain (Daly, 2000: 491). Apart from these structural constraints of the labour market, cultural constraints for the employment of mothers have to be taken into consideration. The social de-familization of the parent will not lead to his/her economic independence via labour market participation if the employment of mothers is culturally rejected. In Belgium, e.g., half of all children between two and a half years and ﬁve years of age were attending child care facilities at the beginning of the 20th century. During the two world wars the number rose to two-thirds of all children in this age group and climbed up to the 100 per cent mark during the postwar period until 1970. But, up to the mid 1970s, this social de-familization of the parent did not result in a growing female employment rate. In contrast, the female employment rate fell constantly from two-thirds to one-third between 1850 and 1960. Yet in 1970, we ﬁnd that Belgian women left the labour market without return after their ﬁrst child had been born (cf. Leitner, 2005). (3) (i) Parents who are economically familized – e.g. by the lack of individualized payments for care or by indirect payments for care or by insuﬃcient market income – are usually seen as socially dependent which means that they are obliged to take over child care. (c) But: This does not necessarily have to be the case. Parents could be economically familized and socially independent – i.e. free from child care obligations – at the same time, if e.g. a parent becomes (long-term) unemployed, and thus dependent on the income of the other parent, but does not increase his/her engagement in child care since the child has free access to extra-familial child care facilities anyway. The social independence of the economically familized parent would be best supported by child care services which not only have the function of enabling the reconciliation of work and child care (by just ‘billeting’ children), but which also aim at providing a high-quality educational function for the child.14

Conceptualizing and measuring ‘de-familization’

257

(4) (i) If parents are economically de-familized by an income from labour market participation, they could increase their social independence (and commonly are supposed to do so) in so far as child care is taken over by other family members or by child care services. (c) But: Social independence of parents with regard to their children will never be (and arguably should not be) reached completely. The economic defamilization of the parent could even strengthen his/her social dependence, if it comes through individualized payments for care. Quite interestingly, in Finland, parents were given the option to choose between the right to a daycare place for their children and a Child Home Care Allowance (CHCA) for those who did not take up a day-care place. This led to a high percentage of parents opting for the payment for care instead of the day-care place: in 1998, 45 per cent of children under three were cared for through CHCA whereas 24 per cent were covered by day care (Kröger et al., 2003: 40–3). Thus, the majority of parents opted for economic de-familization and social dependence. A lack of child care services and of inner-familial care sharing will also serve to uphold a high level of social dependence of the economically defamilized parent. Especially for working women (as opposed to men, at least in many or even most cases), de-familization in the sense of social independence from child care (and from familial as well as social child care expectations) can be said to be a chimera. What should have become clear at this point in our chapter is that ‘defamilization’ is a complex and, in terms of its potential for ‘autonomization’, highly ambivalent concept. To measure the degree of ‘dependency’ or ‘independence’ of care givers, then, it is of crucial importance to be clear about the dimensions of de-familization as well as about the facets of (female) independence that are under consideration. Under these circumstances, it should be uncontroversial at least analytically – if not politically – that diﬀerent dimensions and degrees of female (in)dependence would have to be distinguished with regard to both the familization and de-familization of care givers in advanced welfare states. Moving now – if only brieﬂy – on to the perspective of the care receiver, i.e. the child to be cared for by his or her parents, the ‘de-familization game’ becomes even more complicated. In the dominant discourse as reviewed above, de-familization is almost self-evidently supposed to be in the interest not only of women (because of it paving their way into the labour market) and the society at large (because of the mobilization of the hitherto untapped female labour reserve) but also of children. Children (or rather: many of them) are said to proﬁt from being de-familized because of the improvement of their life chances brought about by detaching their education at least partially from their families (and thus relieving them

258

Capturing the nature of welfare state change

from their families’ educational failure; cf. Esping-Andersen, 2002b). But if the child’s perspective on de-familization really was to be taken seriously, things would look quite diﬀerent – and rather more complex. Again, as in the case of the care giver’s perspective, there would have to be distinguished a social from an economic dimension of de-familization. The child as the person to be cared for has social needs, on the one hand, and economic requirements, on the other. The child’s social needs may be familized, meaning that his or her care is taken over by one (or both) of the parents, or they may be de-familized, care being then delivered by other institutions (private or public services). Similarly, the child’s economic needs may be met by his/her family, i.e. the costs of child raising may be internalized into the parents’ household and thus familized; or these economic needs may be eﬀectively de-familized in the sense of externalizing, i.e. socializing the cost of children (by way of public transfers to households with children covering part or the whole of their child related expenses). As opposed to the case of the parent as the care giver, the child as care receiver cannot be supposed – the younger, the less – to be in a situation to make real choices between the familization or de-familization of his/her economic and (even less so) social needs; real-world children do not opt for social or economic dependence upon or independence from their families. But to do justice to children as a constitutive part of the child–parent care relationship, we should take into consideration the ‘would-be’ choices of children with regard to them being (de-)familized – choices (children as) real actors would make. In this sense, it is not too adventurous to assume that indeed economic de-familization is always in the child’s interest as care receiver. With regard to social de-familization, however, things are less clear, and it would seem to be in the child’s interest to really have, as far as possible, a real choice between being cared for by one of his or her parents, by both of them, by other family members (wherever applicable) or by extra-familial care givers – or even by a combination of two or more of these options. Just like in the case of a women-friendly welfare state, a ‘children-friendly welfare state’ would, above all, enable choices – and take children seriously as an essential and equitable part of the care relationship.

CONCLUSION Having said all this, we may keep our concluding section short and restrict it to two ﬁnal remarks, an analytical and a political one. With respect to the analytical remark, we would like to ﬁnish our chapter by paraphrasing Esping-Andersen (as quoted in the introduction): ideological predilections aside, it should be evident to all that we cannot aﬀord

Conceptualizing and measuring ‘de-familization’

259

not to deconstruct and diﬀerentiate the concept of ‘de-familization’ in advanced welfare state research of the 21st century. Taking ‘de-familization’ (analytically) seriously means taking into account both sides of the care coin: care givers and care receivers, parents and children alike. Care is ‘inherently relational’ (Lewis and Giullari, 2005: 94) – which means that not only women, but women, children and even men have to be analysed with regard to their needs, wants and interests concerning the familization or defamilization of care. Women’s, children’s and men’s autonomy and interdependence must be accounted for by an analytically sound concept of de-familization. Thus, the mainstream conceptualization focusing on liberating women from care burdens in order to guide them into (alleged) economic independence via labour market participation is only one possible variety of de-familization – and, to be sure, one that acknowledges gender equality, care work and children’s rights only ‘in a particular, partial and instrumental way’ (Lewis and Giullari, 2005: 78). In this context, a political remark may be permitted as well. If what is at stake is a welfare state that gives ‘a real choice’ – not only to women, but to children and, quite unconventionally, even to men – concerning the issue of care, its ‘familization’ or ‘de-familization’, we would have to head for a basic-income welfare state which would indeed leave the shaping of social relations of care open to the autonomous and interdependent decisions of its (family) citizens (van Parijs, 1995). Choice is socially ‘embedded’ and ‘genuine choice’ or ‘real freedom to choose’ in respect of the balance of paid and unpaid work at the level of the household (and hence gender equality) will involve not only a rebalancing of paid work between men and women, but a complicated rebalancing of unpaid work between the market, state and men and women. (Lewis and Giullari, 2005: 78)

If we include children as fully-ﬂedged members of the care/work relationship in this picture of a world of ‘real choices’, we get an impression of what de-familization is – or should be – about: the collective well-being of women, men and children being part of a social collectivity of care givers and care receivers. Instead of subjecting care and care relations to productivist policy designs, we should wonder about how social policies could do justice to the complex arrangement of autonomy and interdependence – and of time, money, and love – which ‘care’ is all about.

Capturing the nature of welfare state change beneﬁts are less disciminatory since they are not means tested, their ﬂat-rate character makes them equally inferior to social security beneﬁts. The expansion of public care services distinguished the Scandinavian model from other welfare states and was acknowledged (in principle) as a women-friendly policy by feminist social policy research though Scandinavian feminists also identiﬁed a trade-oﬀ between economic independence and dependence on the state for public services (Borchorst and Siim, 1987: 138). Or as Jane Lewis (1997: 173–4) puts it: (1) the right to do unpaid work and not to engage in paid work or (2) the right to do paid work and not to engage in unpaid work. Ilona Ostner (2004) discusses and criticizes this ‘ideological’ narrowing of the feminist debate which according to her eventually came to dominate the editorial policies of the main journal of feminist welfare state research, Social Politics. Obviously, family care could not be received by right, although if we think of the care relationship between parents and children, the care obligation of the parent is very strong, and sometimes even enforced by the law. Elisabeth Hammer and August Österle (2003: 41f.) propose – from a care giver perspective – to measure de-familization by (a) the freedom of choice to provide care due to payments for care and (b) the freedom of choice not to provide care which for them depends on the availability and accessibility of social services as well as on the care giver’s access to the labour market. Care relationships between (non-demented) adult persons diﬀer from parent–child relationships in many respects. It is beyond the scope of this chapter to refer to these diﬀerences in a comprehensive way, but we will at least give some references when they seem appropriate. Similarly, in old-age care the care giver (usually) feels an obligation to care whereas the care receiver (usually) expects the family to provide care. Similarly, in old-age care the care giver could be socially de-familized by care services for the elderly or if care giving is shared with other family members. Due to the fact that in many cases the care giver is the partner of the care receiver, the idea of care sharing between partners is much more widespread with regard to child care than in terms of elderly care. In elderly care the social de-familization of care receivers would mean to enable them to become independent of the availability and willingness of family members to provide care. Easy access to social care services would guarantee this kind of choice. An intercessor would also be a necessary prerequisite for the social de-familization of demented care receivers. Payments that are adressed to the care receiver – as it is often the case in old-age care – will not (or only in a very indirect way) contribute to the economic de-familization of the care giver. This critique refers to mainstream social policy research. In contrast, feminist research comprises a much more comprehensive discourse on care (for an overview see Leira and Saraceno, 2005). From early on, care giving was analysed as a ‘labour of love’ (Finch and Groves, 1983) with a highly complex social dimension of interpersonal relationships of love and obligation. The interconnectedness of ‘caring for’ and ‘caring about’ (cf. Tronto, 1993; Sevenhuijsen, 1998) as well as the mutuality of the care relationship were described as a special ‘rationality of caring’ (Wærness, 1987). Moreover, care policies as well as policies to bring carers into paid employment have been a central ﬁeld of analysis (e.g. Ungerson, 1997; Lewis, 2002; Gornick and Meyers, 2003). It should be noted, though, that services and payments are probably not used simultaneously. Parents would rather consume parental leave beneﬁts immediately after the birth of the child and make use of care services later on. The sharing of care work within the family might be a less legitimate claim if one parent is not in the labour market.

12. Pension reform: beyond path dependency? Sven Jochem Change is eternal. Nothing ever changes. Both clichés are true. (Immanuel M. Wallerstein, 1974: 3)

INTRODUCTION1 It hardly seems necessary to emphasize that over the past two decades mature welfare states have changed in more than one respect. How can we assess these changes? Do these developments reﬂect dynamic adaptations of welfare programmes which, in the end, reinforce the basic welfare state institutions that had been founded several decades ago? In other words: are contemporary changes path dependent? Or do these changes imply programmatic and institutional innovations which alter the fundamental logic of welfare states? Contemporary welfare state research focuses on the question whether historical welfare paths are stable or undergo profound changes, which would imply that they have transcended the boundaries of historical paths. In this respect, the concept of path dependency is widely used, especially in comparative pension policy research. This chapter discusses basic dimensions of the path dependency concept in comparative welfare state research (cf. Thelen, 1999; 2004; Mahoney, 2000; Schwartz, 2000; Pierson, 2004; Streeck and Thelen, 2005). Diﬀerent approaches to measuring processes of path dependency are introduced, discussed (second section) and confronted with results of case studies on recent pension developments in Denmark, Germany, the Netherlands, and Sweden (third section). Developments in mature pension systems are chosen because they serve as the locus classicus for path dependency arguments (Myles and Pierson, 2001). As a conclusion in the fourth section, I argue that path dependency is indeed a valuable concept which helps to understand contemporary welfare dynamics. The core problem of this approach, however, is the concise measurement of welfare state paths as well as the speciﬁc assessment of crucial thresholds which mark path departures. 261

Capturing the nature of welfare state change

PATH CONSTRUCTION AND DIMENSIONS OF CHANGE The path dependency concept was originally used to circumscribe the eﬀects of economic and political institutions on economic and political dynamics of change. Within the broad ﬁeld of contemporary neo-institutionalism, the concept was particularly discussed in the historical branch of the research community. Thus, the impact of historical patterns and speciﬁc political ‘rules of the game’ (Immergut, 1992) on welfare policies was analysed. Political institutions introduced earlier in history were assumed to have speciﬁc eﬀects on policy making processes at later points in time, even if the political basis which led to the introduction of these institutions years ago was no longer in place. In other words, the historical inertia of institutions has an impact on future welfare developments. One might argue that this perspective, applied to welfare state dynamics, corresponds with the famous ‘freezing-hypothesis’ in party system research, formulated decades ago by Lipset and Rokkan (1967). In the literature dealing with this issue most attention is currently paid to the question of how institutions determine political behaviour. As Beyer (2005) shows, at least seven mechanisms might explain why a particular path chosen in the past is often followed in the future. Historical ‘sequencing’, the ‘layering’ of institutions, or ‘positive returns’ built into institutional conﬁgurations, to mention but three of such mechanisms, shed light on the diﬃculty of changing historically shaped paths. However, as Beyer (2005), Ebbinghaus (2005), Pierson (2004) or Streeck and Thelen (2005) emphasize, the same mechanisms which stabilize developmental paths may also be conducive to path departures if, for example, the political environment changes or political actors change their preferences. Beyond ‘simple’ notions of path dependency, which claim that there are some insurmountable lock-in eﬀects blocking path deviant developments, there are also more ‘enlighted’ versions of the concept which aim to explain institutional path stability as well as path departure (for an early critique of this ambition cf. Schwartz, 2000). In the context of this volume, it is not the causal eﬀects of political institutions, nor the usage of the path dependency concept as an independent variable, which this chapter concentrates on. Some of the theoretical aspects of path dependency will be discussed, but excursively in the case studies that follow. The main focus here is the use of the concept as a ‘dependent variable’, or a metaphor for the dependent variable, indicating the degree of welfare state change or continuity. Within comparative welfare state research the path dependency thesis is attractive to those commentators who do not regard the numerous changes during the past decades as having fundamentally altered the logic of modern welfare states. Nor have such

263

changes diminished cross-national diﬀerences. Analysing national welfare states as an entity, contemporary research is dominated by three ‘holy trinities’. Assessed from a macro or ‘bird’s eye’ view (Siegel, 2002), the familiar concepts of diﬀerent paths include the three ‘Regimes of Welfare Capitalism’ (Esping-Andersen, 1990; 1999), the diﬀerent ‘Families of Nations’ (Castles, 1993; 2004) and the three ‘Varieties of Capitalism’ (Hall and Soskice, 2001; Hall and Gingerich, 2004). All these macrotypological approaches rest on a great number of diﬀerent concepts, variables and data, quantitative as well as qualitative in nature, which were put together to describe the overall dynamics of diﬀerent welfare paths. In accordance with these ‘holy trinities’ recent research has provided empirical evidence supporting the notion of path dependent dynamics. In the words of Gøsta Esping-Andersen: ‘In sum, within the advanced industrial democracies the contemporary politics of the welfare state is a politics of the status quo’ (Esping-Andersen, 1996b: 266–7; cf. also Esping-Andersen, 1999). Using public spending data, Francis G. Castles (2004) too provides evidence in favour of path dependent developments. Using his ‘family of nations’ concept as a means of grouping advanced OECD democracies, he concludes: ‘What appears to have been occurring during this period [i.e. 1980 until 1998] was that aggregate spending levels within expenditure share types and families of nations were becoming internally more homogeneous, without the spending levels of the types themselves necessarily becoming markedly more similar to each other.’ Indeed, Castles argues that incremental reforms seem to even stabilize historical paths and continue to foster cross-country diﬀerences. In those cases in which the political foundations of speciﬁc welfare institutions withered away, ‘their welfare state eﬀects are likely to live long after them’ (Castles, 2004: 176). As a conclusion he predicts: ‘The diversity of welfare state regimes and families of nations is with us for the long-term’ (Castles, 2004: 174). In a similar vein, Peter A. Hall and Daniel W. Gingerich conclude their empirical analysis of the dynamics in diﬀerent varieties of capitalism in favour of a path dependent explanation: ‘On balance, we read these ﬁgures as an indication that institutional practices did not converge dramatically across political economies during the 1980s and 1990s [. . .] The absence of wholesale convergence in the face of the substantial economic pressures experienced during the 1980s and 1990s suggests that the distinctions drawn by the varieties of capitalism literature between diﬀerent types of political economies are likely to be relevant for some time to come’ (Hall and Gingerich, 2004: 35). I do not intend to explore these macro paths and their contemporary dynamics in any detail at this point (cf. Scruggs, Chapter 7, this volume). It will suﬃce to note that these assessments are based mostly on quantitative

264

data covering the aggregated output side of complex welfare state processes. Esping-Andersen (1999) combines quantitative data with some qualitative data, but he too concentrates to a great extent on the output side of the policy process. Hence, these perspectives on welfare state paths cover only a limited range of possible path characteristics. Possibly exceeding the methodological potential of this ‘bird’s eye’ perspective, particularly programmatic proﬁles of diﬀerent welfare states are not covered in any detail. In what follows, I shall disentangle the ‘dependent variable’ and the path dependency concept to a certain extent and focus on pension paths and their dynamics during the past two decades. Due to the complex nature of the path dependency concept I follow Jørgen Goul Andersen (2005) who argues that the measurement of this concept should – at least – cover three dimensions: the (1) basic political process, (2) the basic programmatic rules and (3) the main outcome of welfare systems. Before discussing some possible measurements of each of these dimensions, however, it needs to be emphasized that at the start of empirical research which addresses the question of path dependency, major political institutions are regarded as crucial. In other words, formal institutions such as corporatism, proportional representation, or bicameralism, inﬂuence the policy making process in the welfare state. From this perspective, political institutions ﬁgure as independent variables whereas the policy output is the dependent variable. Paul Pierson has suggested that we transcend this separation by arguing that programmatic rules of welfare policies should themselves be interpreted as institutions. ‘Leaving aside the formal institutions typically explored by sociologists, the institutions that impinge on the modern citizen most directly and intensively as she goes about her daily life are in fact public policies, not the formal political institutions that have preoccupied political scientists’ (Pierson, 2004: 165, emphasis in original). This broadening of the institutional concept has the merit of covering exactly those policy rules that determine the ‘rules of the game’ in welfare policies to a great extent. The programmatic logic of PAYG pension schemes or the programmatic logic of labour market policies (cf. Clasen and Clegg, Chapter 8, this volume) diﬀer across countries and, as we can assume, imply diﬀerent rooms for manoeuvre for policy makers. But by accepting this broader perspective of the institutional path dependency concept, the contours of the welfare state become even more blurred. Especially the analytical separation between the dependent and the independent variable becomes a knotty problem in empirical research. Additionally, while formal political institutions are most of the time ‘sticky’, we can assume that welfare policies are not as stable as basic political institutions, such as constitutional structures. Hence, Pierson’s broadening of the path dependency concept further challenges valid measurements of welfare state changes as well as their explanations.

Pension reform: beyond path dependency?

265

The path dependency argument for mature pension systems is discussed controversially in the literature. Assessing programmatic changes within this policy ﬁeld some authors argue that most recent developments scarcely transcend historical paths (cf. Myles and Pierson, 2001). Others challenge path dependency arguments. As Karl Hinrichs (2000) states, the pension ‘elephants’ seem to be ‘on the move’ (cf. also Hinrichs and Kangas, 2003). And according to Martin Hering’s analysis of European pension schemes, due to the impact of the European monetary regime, a process of convergence is actually taking place within the European Union (Hering, 2005). Therefore, the current scientiﬁc dispute addresses the crucial question whether observable empirical changes are ‘minor’ or ‘big’, ‘not important’ for the logic of the system or, quite the contrary, changing the ‘fundamental rules’ of pension systems – and should therefore be seen as path breaking. How can we conceptually disentangle pension paths in a way that enables us to measure pension policy characteristics and their dynamics over time? First, the political process is crucial. Pension policies are naturally focused on long time horizons. This helps to explain that policy making in some European countries has been based not on political competition but on consensual reform practices. Policy consensus may entail broad issue-coalitions or a corporatist integration of interests into the framing of, and decision on, policy reforms. Therefore, the ﬁrst measure of the welfare path should be a categorization of the political process in a dynamic perspective. Second, the policy proﬁle of pension policies may be disentangled through diﬀerent perspectives on diﬀerent pension pillars and tiers (cf. Figure 12.1). Representing the ‘sector’ of a speciﬁc pension scheme the ﬁrst pillar stands for the public sector, the second for the occupational sector, and the third for the private sector. This perspective makes use of the distinction between the state and the market sphere which is a prominent basic categorical diﬀerentiation in welfare research. Furthermore, the term ‘tier’ will reﬂect the type (or logic) of pension beneﬁt. It matters whether beneﬁts are targeted, minimum, ﬂat-rate, earnings related or deﬁned contribution. In this perspective, an additional distinction between mandatory and voluntary pension schemes becomes essential. Disentangling complex pension schemes further, it is possible to diﬀerentiate between various schemes for diﬀerent occupational groups. Due to a lack of space such an undertaking is not possible in this chapter (but see the contributions to Anderson et al., 2006). In Figure 12.1 these perspectives, as well as some examples from European pension systems, are displayed. Applying this analytical perspective it becomes possible to localise programmatic changes. Hence, we know where to look. But this does not imply that we also know exactly how to measure the scope, extent or the quality of change. To address this problem, I propose a combined strategy.

we can measure programmatic proﬁles for each pillar of a pension scheme, using the full range of information available, i.e. spending and ﬁnancing data, programmatic rules, and changes to the programmatic proﬁle of a speciﬁc pillar. Second, the outcome of pension schemes is to be assessed in this broader perspective, too. The replacement rate of the ﬁrst pillar, for example, may be measured as well as the overall performance of pension schemes to avoid poverty in old age. Such an approach leads to two further challenges. First, how is it possible to measure programmatic rules? As Clasen and Clegg (Chapter 8, this

Pension reform: beyond path dependency?

267

volume) argue, we can assess programmatic tendencies in a qualitative way. For pension policies I follow Hinrichs and Kangas (2003) who argue that the logic of the pillar mix should be the basis for the assessment of change. However, the crucial question in assessing the dynamics of change is: how can crucial thresholds be deﬁned? When is a change still to be classiﬁed as path dependent, and in which cases do the dynamics transcend the historical path and result in path deviations? Here I propose a two-step procedure. As a ﬁrst step, the overall programmatic contours of four European countries are illustratively sketched for the early 1980s. As a second step, the dynamics are described and measured. As a process, path departure is deﬁned as a dynamic of change where the basic logic and the basic mix of the diﬀerent pension pillars have changed (here since the beginning of the 1980s). Based on this deﬁnition, the introduction of a new pillar is to be seen as step towards path departure. Additionally, a process of path departure can be assumed if signiﬁcant changes in the programmatic perspective occur. A signiﬁcant change in the political process alone may not automatically imply new pension rules (albeit changing political constellations may provide the leeway for programmatic changes in the future). Similarly, the output of pension systems is determined at present by old programmatic rules. From an output perspective it seems necessary to measure the current output performance as well as taking account of output forecasts for the near future. The political processes as well as the outcome of pension schemes provide additional information, but the decisive measurement is the programmatic proﬁle of national pension schemes. In sum, the measurement of institutional path dependency or path departure is a complex endeavour. As a means to disentangle the path dependency concept it seems useful to measure change or continuity in the political process, the programmatic proﬁle, and selected outcome dimensions. However, the programmatic dimension especially is diﬃcult to measure. As will be shown below, the perspective of pillars and tiers, as well as the use of qualitative and quantitative data, might provide a ﬁrst step towards measuring pension system dynamics across several countries over time.

PENSION DYNAMICS – BEYOND PATH DEPENDENCY? At the beginning of the 1980s, the pension systems of Denmark, the Netherlands, Sweden, and Germany were clustering into two families with distinctive historical legacies. In the ﬁrst, Germany represented the protoBismarckian country which had pioneered and established a public PAYG

268

system for industrial workers in the 1880s. Subsequently, this pension system was extended, particularly remarkably after World War II, in respect of coverage, beneﬁt levels, and range of entitlements. In contrast, Denmark, Sweden, and the Netherlands are all members of the family of Beveridge countries, in which pension policies developed out of the ‘poor-law’ tradition. During the 1960s, the Beveridge countries split up, as Sweden successfully implemented a mandatory public complementary pension scheme (ATP) (Hinrichs, 2000). However, the Swedish pension system still diﬀered from the German one, as the dominant ﬁrst pillar had been supplemented by a multitude of occupational pension schemes since the 1960s. Before the introduction of the ATP system, labour market parties already negotiated occupational pension schemes. In the early 1980s the coverage for white collar employees and blue collar workers diﬀered by between 10 per cent and 40 per cent (Palme and Svensson, 1997: 20). In Denmark and the Netherlands, in contrast, a similar shift towards the Bismarckian model did not occur. In both countries, complementary pension schemes were more or less absent until the early 1980s (in Denmark), or occupational pension schemes served as a functional equivalent for those

pensioners who looked back on lengthy employment careers. Regulated by the state but negotiated by labour market parties, an early dispersion of occupational pension schemes was observable in the Netherlands. Applying the conceptual map of pension policy changes outlined in the previous section, until the early 1980s the German as well as the Swedish pension path relied on the ﬁrst pillar and the ﬁrst and second tier. In Sweden, the second pillar had already been growing in size and importance since the 1960s. In contrast to Germany it should be noted that in Sweden a minimum protection level was established through the national basic pension. Unlike this ﬁrst group, Denmark relied on the ﬁrst pillar and the ﬁrst tier, whereas the Netherlands relied on the ﬁrst pillar and a quasi-mandatory second-pillar, i.e. a mixture of mandatory occupational and voluntary occupational schemes (cf. Figure 12.2). Voluntary private pension schemes are not covered in this overview. What happened after the early 1980s? For which countries are path departing pension dynamics observable? And what were the political reasons for continuity and change? These questions are addressed in the following case studies. Denmark – Incremental Path Departure Introduced in 1956, the universal pension scheme was the cornerstone of the Danish pension system until the early 1990s. In 1964, the government and the Danish parliament agreed to expand this pillar towards a generous, ﬂat-rate, tax ﬁnanced universal pension scheme (the reform came into force in 1970). The upgrading of the universal pension scheme was partially the consequence of blocked ambitions which had been pursued by major parts of the Danish Social Democrats (SD) who had preferred the path chosen by the Swedish ‘brother’. They aimed at layering the basic pension scheme with a generous and mandatory income related state pension scheme. Because of the weakness of the SD in parliament, and because of internal splits in the trade union movement, this reform ambition was watered down. Instead, a marginal ATP scheme was introduced which by no means guaranteed income maintenance after the age of 67, the then oﬃcial retirement age (which was reduced to the age of 65 only in 2002) (cf. GreenPedersen, 2006). This political defeat of social-democratic pension plans in Denmark did not only cause a signiﬁcant divergence from the development of the Swedish pension system. This political stalemate also left the question of how to regulate an income related pension scheme unsettled. Danish civil servants, and increasingly since the 1960s, white collar employees in the public sector, had privileged access to funded occupational pension plans.

270

Capturing the nature of welfare state change

Since 1956, the government had provided marginal subsidies for private and occupational pension schemes. While in 1960 approximately 20 per cent of all employees were covered by occupational pension schemes (mainly in the public sector), the coverage increased only slightly until the early 1980s (to approximately 35 per cent of all Danish wage earners). As a consequence, the majority of the working age population was not covered by occupational pensions and relied on the (relatively generous) basic pension scheme (Green-Pedersen, 2006). The labour movement criticized this situation as low-wage earners especially faced old-age poverty. During the 1980s, the SD as well as trade unions pushed the bourgeois government to make occupational pension schemes mandatory for all wage earners. After the national elections in 1988, the bourgeois coalition lost its tacit support in parliament and had to rely on the right-wing populist Progress Party – or the SD. As a consequence and to calm down tensions in labour relations (cf. Jochem, 2003), the executive revitalized tripartite concertation talks. The broad pension commission (Arbejdsmarkedpensionsudvalget) favoured mandatory occupational pension schemes but the bourgeois coalition was internally split on this issue. While employers and employees in the public sector continued to expand occupational pension schemes through self-governance, the trade unions in the private sector hesitantly waited for legislation and focused exclusively on wage issues. The government ﬁnally invited the largest party in opposition, the SD, to negotiations. As Green-Pedersen argues (2006), the executive was willing to accept a legislative solution in exchange for commitments on the part of the SD on tax and other reform issues. However, aiming to strengthen its proﬁle as a tough opposition party, the SD eventually undermined negotiations. When negotiations failed, the Metalworkers Union changed its strategy and opted for occupational pension schemes regulated via wage bargaining, which were, for the ﬁrst time, negotiated in 1991. This reform process – together with the adjustment in 1993/94, which made national pensions more means tested – paved the way for an impressively rapid spread of occupational pension plans. Currently up to 93 per cent of all Danish employees are covered by occupational pension plans (Green-Pedersen, 2006). As a result, a universal ‘ “Rolls Royce” version of ﬂat rate universalism’ (Goul Andersen, 2002a: 133) is now combined with occupational income related and funded pension schemes. Given the broad coverage of wage negotiations, occupational pensions have become ‘quasi-mandatory’ (Green-Pedersen, 2006). For the ﬁrst pillar, the government is the responsible regulatory body, overseeing the expansion of means testing in 1993/94. For the second pillar, trade unions and employers’ associations

271

negotiate and regulate occupational pension issues without state interference. Hence, the development of the Danish pension scheme led to a multipillar scheme that went beyond the old pillar structure and logic. A parliamentary stalemate, ineﬃcient tripartism, and the politics of nondecisions opened up the way for social partners to transcend their role to move beyond wage bargaining. This ‘silent revolution’ (Goul Andersen, 2005: 7) may be interpreted as a path departure which is not observable in public pension spending data (which remained rather stable). Hence it clearly shows that expenditure ﬁgures are to be interpreted very cautiously and are not useful as an indicator of change (or continuity) for this type of outcome. Additionally, new actors entered the policy ﬁeld, new pension schemes expanded rapidly without direct interference of the executive – a paradigmatic case of incremental path departure. Germany – Incremental Path Layering Germany is one of the most cited examples of reform gridlock and path dependent welfare state change. Despite numerous reform steps, it is argued that path dependent and incremental change was prevalent until the end of the 1990s (Alber, 2000; Jochem, 2001; Schmidt, 2005). The last encompassing pension reform before German uniﬁcation was passed in parliament in 1989 and, with most parts becoming eﬀective in 1992 or later, contributed to a continuation of the historical path (Hinrichs, 1998) despite far reaching cost containment measures (Schulze and Jochem, 2006). Until the mid 1990s Norbert Blüm, the Minister for Labour and Social Aﬀairs then in oﬃce, repeated that the future of German pensions would be safeguarded, despite the ﬁnancial burden of German uniﬁcation, and high and increasing unemployment, as well as ongoing demographic change. Consequently, in the process of uniﬁcation the West German pension system was transferred to the former GDR, based on a generous beneﬁt calculation mechanism for most pensioners in the East. From the mid 1990s onwards, the centre-right government started to opt for new policy instruments in the ﬁrst pillar. However, these innovations (e.g. the introduction of a ‘demographic factor’ inﬂuencing the uprating of pension levels) were postponed and ﬁnally abolished by the red-green government after 1998. Furthermore, the Grand Coalition in pension policies between the ruling Christian Democrats and the Social Democrats in Opposition was eroded further during this time. While there were some new policy ideas swirling around in the public debate, during the last few years of the centre-right coalition no structural innovations were implemented. By and large, the Kohl government restricted its reform eﬀorts to cost containment measures.

272

Capturing the nature of welfare state change

After some fumbling of the red-green government on welfare policies, in 2001 a pension reform changed the contours of the German pension scheme (Trampusch, 2005b). As Winfried Schmähl put it, the 2001 reforms marked a ‘paradigm shift’ in German pension policies (Schmähl, 2002; see also Hering, 2003; Hinrichs, 2004; Rüb and Lamping, 2005). The replacement rate was signiﬁcantly reduced. The joint (employer and employee) contribution rate was capped at 20 per cent of gross wages. In order to compensate for the traditional principle that the ﬁrst pillar should secure the standard of living of pensioners (Lebensstandardsicherung), the government subsidized private pensions (Riester-Rente), targeted especially at the lowincome brackets. After political negotiations and the intervention of trade unions, the opportunity for occupational pensions (Entgeltumwandlung) was included in the system of tax incentives, thereby giving the labour market parties new responsibilities (Schmähl, 2004). The reform complemented or layered the old pension system, which will in fact change the public-private mix of future pensioner generations. This paved the way (as was the case in Denmark) for new actors – private insurance companies – to enter the inner core of pension policy making. Because of far reaching tax incentives it also gave the Ministry of Finance an important veto power in this policy domain (Rüb and Lamping, 2005). In 2004 this ‘direction setting law’ (Rüb and Lamping, 2005: 2) was complemented by two reforms which openly rejected the idea that pensions provided by the ﬁrst pillar could secure a standard of living which used to be the norm. Under the heading of a ‘sustainability factor’ the replacement rate was further reduced in the ﬁrst policy package. Its construction enables the government to adjust pension upratings in an ad hoc fashion if the combined contribution rate of employers and employees threatens to rise above the ﬁxed limit of 20 per cent. Additionally, the second reform (following a verdict of the Constitutional Court) will make future pension beneﬁts taxable, which implies a further reduction of the net replacement rate. Undoubtedly, many parts of the old system still exist and for most retired Germans the bulk of pension income will continue to be provided through the ﬁrst pillar pension in the near future. A successful ﬁnancial consolidation of the public pension schemes has not occurred. On the contrary, public pension spending has been steadily increasing since the 1990s. The reduction of beneﬁt levels will be noticeable after 2010 at the earliest. Nevertheless, the logic of the German pension system has changed. The role of the ﬁrst pillar has been reduced and will be further diminished in the future. Until today, the incentives of the Riester-Rente are only used scantily, especially by low-income earners. However, under the Grand Coalition, in 2005 the government announced that mandatory private or occupational pension schemes were not necessary and, hence, law making not on the

273

political agenda, because coverage rates for both private and occupational voluntary schemes were increasing (Rentenbericht, 2005). In order to dampen future expenditure growth for the ﬁrst pillar, the Grand Coalition decided to increase the oﬃcial retirement age to 67 years. This change will be gradually implemented between 2007 and 2029. Incrementally, the pension system, the pillar mix and the logic of the whole pension system will change due to these and more recent reform measures. The future replacement rate of the ﬁrst pillar will be signiﬁcantly lower than at present and a consensus is observable in the political discourse as all political parties emphasize the increasing importance of occupational and private supplementary pensions. The prototypical Bismarckian German pension system has thus started to change its path due to institutional layering with supplementary and voluntary pension schemes. The Netherlands – Path Dependent Policy Blockage The Dutch pension system illustrates the power of policy inertia and path dependency because of reform blockages. In the Netherlands, a complex multi-pillar pension system with a universal basic pension scheme emerged after World War II (adopted in 1956), which is complemented by occupational pensions. The universal basic pension is ﬁnanced through contributions (in 2005 the contribution rate stood at 17.9 per cent of gross wages). Every Dutch resident over 65 (with 50 years of residence)2 beneﬁts from the basic pension (AOW). This ﬁrst pillar scheme is complemented by funded earnings related occupational pensions. As early as 1908, the Dutch state regulated occupational pensions for the ﬁrst time and 750 diﬀerent occupational pension funds existed by 1938. Today, approximately 90 per cent of all wage earners are covered by occupational pension schemes. De jure, the Dutch government has the power to declare occupational pensions as mandatory for speciﬁc economic sectors. The government provides far reaching tax incentives in order to stimulate coverage of these pension schemes. In 2003, these tax deductions amounted to 2.1 per cent of GDP (Anderson, 2006). Since the implementation of the AOW, the contribution rate to the basic pension scheme increased signiﬁcantly from 6.75 per cent of gross wages in 1957 to 17.9 per cent in 2001 (Anderson, 2006). One prominent measure used frequently by governments since the 1980s has been to freeze the universal pension beneﬁt. For three subsequent years (1993, 1994, 1995) the indexation of pension beneﬁts was suspended (Visser and Hemerijck, 1997). However, as most political observers of the 1994 general elections commented, the then major party in government – the Christian Democratic CDA – had to pay a high price for these cost containment measures. Two

274

Capturing the nature of welfare state change

parties representing the interests of pensioners were able to gain votes and entered parliament for the ﬁrst time. And as a consequence of a disastrous electoral defeat, for the ﬁrst time since 1918 the CDA was not part of the ruling coalition government. Instead, the Social Democratic Party (PvDA) together with two liberal parties (VVD, D66) formed a ‘purple coalition’ in 1994. The new government blocked the cost saving measures which the previous government had suggested and tried to introduce new calculation rules for supplements in the AOW. However, after ﬁerce opposition, the coalition withdrew this reform initiative. Since the 1994 national elections, cost containment measures in the AOW seem to be politically taboo. The PvDA started to discuss the future role of the basic pension and publicly deliberated whether well-oﬀ pensioners should contribute to the ﬁnancing of the scheme (which would in eﬀect imply means testing) and to set up a supplementary pension fund to cushion the impact of the future increase of the number of pensioners as a result of demographic change. After ﬁerce political debates, the government failed to reach its goals. In eﬀect, an AOW fund was established, but the government feeds this fund with taxes and through contributions. Well-oﬀ pensioners were not obliged to co-ﬁnance this fund. Hence, Dutch reform politics could not structurally alter the basic pension scheme, but policy blockage implied the introduction of a functional ‘lifebelt’ for the AOW for the time when the baby boomers approach retirement age. A discussion of the politics and policies of pension reform in the Netherlands cannot exclude a major area of reform: the disability pension scheme (WAO) as the ‘jewel in the crown’ of the social security system (Kuipers, 2004: 150). Introduced in 1967, the Dutch disability scheme serves as a major route from work to welfare. Since the economic crises of the 1970s and 1980s, a steady inﬂow of participants has induced huge ﬁnancial burdens. The Grand Coalition ﬁrst introduced cost containment measures in the WAO in 1991 (tightening access criteria, reducing beneﬁt replacement rates and other measures). This caused the largest public protest march since World War II (Hemerijck, 2003: 249). In 1992, the focus of intervention changed. Now administering the system, the social partners were accused of not following political guidelines. As the head of a parliamentary commission stated: while the historical legacy has led to corporatist administrations, policy making can not suddenly abolish them, however, ‘an attempt must be made to break their power in another way’ (Buurmeijer, cited in Kuipers, 2004: 177). The work of this commission opened the way for a shift in the governance structure of the WAO. This way of making a political intervention enabled the partial privatization of the sickness insurance as well as a

de-corporatization of Dutch welfare administration. Televised hearings in the commission convinced public opinion that the administration was to blame for the Dutch ‘disability crisis’, enabling politicians to forge ahead with this reform despite resistance from the trade unions. But it is necessary to emphasize that this institutional reform neither altered the programmatic instruments of the WAO nor did it result in a decline of the dependency ratio. The Dutch history of pension policies during the past two decades shows how policy inertia shapes future developments. The early dynamics of the second pillar have inﬂuenced the historical dynamic until today. Beyond short-sighted cost containment measures, the members of the executive could not alter the fundamental proﬁle and principal logic of the pension system. Especially in the ﬁeld of early retirement, various governments could not push through institutional innovations. They all failed (to a great extent) because the pension issue was highly prioritized in public debate. Since the elections in 1994, no major party has openly suggested far-reaching structural reforms in the ﬁrst pillar. Blocked pension policies imply dynamics in line with historical institutions, which were only layered by a functional ‘lifebelt’, the AOW fund. It is necessary to note that the Dutch pension system already had a diversiﬁed pillar mix in the early 1980s. Nevertheless, the dynamics during the past decades reﬂect policy stalemate and the status quo regarding the logic of the whole pension system. Sweden – Big-Bang Reform with Path Departure? In the comparative welfare state literature Sweden is usually presented as an example of a country which introduced major reform of a mature pension system. It was an informal Grand Coalition, consisting of the four bourgeois parties in government and the major opposition party, the Social Democratic Party (SAP), which changed the fabric of pension rules in one major policy package. The political circumstances as well as the one-shot political reform process both stand out in a comparative perspective. Sweden was an ‘early bird’ in pension scheme innovation, implementing a basic pension as early as 1914, which was updated and renamed in 1935 (folkpension). Pension beneﬁts were meagre, and in the early 1950s the mean beneﬁt level was only equal to approximately 30 per cent of the average industrial wage (Anderson and Immergut, 2006). Similarly to the Danish situation, employees in the public sector were members of an earnings related occupational pension scheme, and trade unions in the private sector forcefully demanded an earnings related public pension scheme for the whole working population. After several years of policy deliberations and despite highly insecure political circumstances (Immergut and Jochem,

276

Capturing the nature of welfare state change

2006), the national supplementary pension scheme (ATP), as ‘jewel in the [Swedish] crown’ (Lundberg, 2003), passed parliament. Rather unusually for a contribution based public pension scheme the ATP was partially funded.3 Even more importantly, the ATP became a national symbol for social-democratic Sweden (Svensson, 1994; Lundberg, 2003). Hence, due to historical developments, by the early 1980s the Swedish pension pillar mix was to a great extent diversiﬁed. The big pension reform that was agreed upon in 1994 was gradually implemented until 1998 under minority governments led by the Social Democratic Party. Several reform aspects contribute to the conclusion that this pension reform seems to be a ‘radical overhaul of the existing system’ (Anderson and Immergut, 2005: 20). First, the universal ﬂat-rate basic pension was replaced by a new ‘guarantee pension’. Pension levels have been indexed in line with inﬂation since 2003, hence also marking a major shift away from wage or wage and price related pension adjustments. Second, the old ATP deﬁned beneﬁt scheme was replaced by two deﬁned contribution schemes. The new public ‘income pension’ is supplemented by a ‘premium pension’ which is a funded individual account scheme administered by a state agency. Into this ‘premium reserve’ 2.5 percentage points of gross wages (out of a total contribution rate of 18.5 per cent) can be invested in diﬀerent funds. Alternatively the wage earner may decide to let the state administer the money. Third, the new income pension beneﬁts are indexed in line with economic growth and life expectancy. Furthermore, earnings related beneﬁts are now based on lifetime earnings instead of the best 15 out of 30 years. Finally, while in the ATP system pension contributions were paid entirely by employers, the new system is jointly ﬁnanced by employers and employees, each paying half of the contribution rate. Indisputably, the pension reform of 1994–98 changed the dominant pension rules with one major reform step. But from our perspective the logic of the whole system mainly changed the ﬁrst pillar, while other pillars were not directly targeted by the reform. As far-reaching as these changes might be, the programmatic changes ‘only’ altered the functioning of the ﬁrst and second tier within the ﬁrst pillar. The single privatization measure was the introduction of the ‘premium pension’, through which employees have the freedom of choice how to invest the money. It is noteworthy that in 2006 beneﬁt increases in the new system were higher than they would have been under the old ATP rules (Settergren, 2005). Additionally, occupational pensions spread further across the economy. Today, occupational pensions in Sweden are quasi-mandatory (Anderson and Immergut, 2006). In sum, the programmatic rules within the ﬁrst pillar changed to a great extent; the pillar mix, however, remained more or less stable. Therefore, the Swedish case is in our conception of path dependency a borderline case.

Pension reform: beyond path dependency?

277

CONCLUSION Strictly speaking, every policy change is path dependent, as every change in the policy proﬁle responds to problems built into the old system to a certain extent (Goul Andersen, 2005). Hence, pension reform always involves programmatic change and programmatic continuity. Contemporary welfare state research is confronted with the challenge of assessing whether observable changes are undermining historical paths, or have at least the potential to do so in the long run. From a ‘bird’s eye’ view, concepts such as welfare regimes, families of nations, or varieties of capitalism (Esping-Andersen, 1999; Castles, 2004; Hall and Gingerich, 2004) may still oﬀer valuable analytical frameworks for the shape of welfare paths over time. From a ‘micro’ perspective that focuses on changes within existing pension systems, however, we can observe changes which, in some cases, transcend the historical pension scheme logic. In Germany and Denmark, and with some limitations even in Sweden, political reforms and self-steering processes of labour market parties have paved the way for profound new programmatic logics in pension policies. As Hering (2005) and Bonoli (2003b) argue, there is indeed evidence that current pension systems start to converge ‘towards the multipillar end of the spectrum’ (Bonoli, 2003b: 414). Therefore, the usage and usefulness of the path dependency concept depend on the perspective we take. The holistic perspective may provide evidence for dynamic continuity and the robustness of crucial diﬀerences between several countries, while a more detailed perspective, which also takes programmatic dynamics into account, may provide evidence for path departures. The ‘dependent variable problem’ may not be solved with a ‘silver bullet’. Diﬀerent perspectives are not only legitimate but necessary. We should bear in mind that our arguments concerning historical patterns crucially depend on our analytical perspective and categories. This chapter has dealt with the measurement of path dependency in four European pension systems. The proposed analytical perspective covers the political process, the programmatic proﬁle as well as the outcome of pension policy. Three observations can be made. First, analysing pension spending patterns, the overall stability is impressive (cf. Table 12.1). Despite some small ﬂuctuations – and the German trend of increasing spending – the overall assessment reveals continuity. If we analyse spending projections, which are based on OECD calculations and updated by Reimann (2005), the results are diﬀerent. The most severe increases are forecast for the Netherlands and Germany, whereas the anticipated spending increase in Denmark is rather moderate. According to these estimates, the Swedish pension system will face one of the lowest growth dynamics until the year 2050. If the most recent German reforms (between 2001 and 2004) were included the anticipated

spending increase would be only 3.3 percentage points (instead of 5.0) by the year 2050, approaching the group of the best performers (Reimann, 2005: 5). Second, the governance mode changed notably in Denmark as well as in Germany and in Sweden, where the (partial) funding of pension schemes opened access for new policy actors in policy making. In the Dutch case, dismantling the corporatist welfare administration was a notable change. However, the consequence of this development for future programmatic dynamics remains to be seen. Third, as the case studies showed, important changes to the programmatic proﬁle and the mix of pension pillars occurred in Denmark and Germany. The Swedish case stands for an all-encompassing reform in a single step, but it seems questionable whether path departure is really as noticeable as it is considered to be in several assessments of only the Swedish example. The Dutch case provides evidence for policy stalemate and a stable logic of pension policies (cf. Figure 12.3). In all four countries programmatic innovations were inﬂuenced by policy inertia. Hence, to focus on the historical paths provides useful insights into

the dynamics of pension systems over time. Most innovations reported here layered already existing institutions. Both old and new schemes when combined, however, induced a new logic of the Danish and German pension systems. The most impressive case in this regard is the change of the German pension system. In the Federal Republic the pillar mix was expanded stepwise towards subsidized occupational and private pensions. The Danish case is an example of political stalemate and – as a consequence of the encompassing nature of labour relations – of an impressive growth of quasi-mandatory occupational pensions negotiated outside the parliamentary arena. The Swedish development is ambivalent in this respect. Some basic programmatic rules in the ﬁrst pillar have changed. Noteworthy is the introduction of a third tier in the ﬁrst pillar. The expansion of occupational pensions, however, had already been initiated in the 1970s. Strictly speaking therefore, the latest pension reform did not generate a major change within the pillar mix, but mainly recalibrated the rules within the ﬁrst pillar. Finally, the Dutch pension system already represented an example of a diversiﬁed pension system in the early 1980s and

280

Capturing the nature of welfare state change

indicates merely gradual change since then. From this perspective, cost containment in the ﬁrst pillar is the most urgent political question, which has not yet been solved. Up to this point, changes in diﬀerent dimensions have been reported, but how are they measured? Certainly, the assessment oﬀered in this chapter relies on qualitative comparative analyses which are diﬃcult to translate into quantitative data. But the perspective applied opens the way to focus on programmatic innovation. Changes in this dimension are made explicit and are traceable. Because the path dependency concept is in danger of becoming a ‘catch-all’ phrase (Goul Andersen, 2002a: 131), the approach adopted in this chapter provides a clear perspective on pension dynamics. It deﬁnes thresholds of path departures and enables qualitative assessment. The approach applied in this contribution enables us to assess degrees of change and their implication for the pillar mix in mature welfare states. Its application underlines Immanuel Wallerstein’s statement that ‘change is eternal. Nothing ever changes. Both clichés are true’ (Wallerstein, 1974: 3).

For fewer years of residence, 2 per cent is subtracted from the pension beneﬁt for each missing year. 3. The AP funds cushioned the transition costs during the reform. Up to 2004, the AP funds transferred approximately €38 billion to the government budget in order to compensate for the costs of transforming the pension system (Andersen and Immergut, 2006).
