Preferences over jurisdictional architecture are the product of three irreduciblelogics: efficiency, distribution and identity. This article substantiates thefollowing claims: (a) European integration has become politicized in electionsand referendums; (b) as a result, the preferences of the general public and ofnational political parties have become decisive for jurisdictional outcomes; (c)identity is critical in shaping contestation on Europe.

It has been said about the United States that it is now suffering ‘a crisis of regime’. Europe, we have been told, is in little better condition: ‘all over Europe the First World War broke up the structure of society which, before 1914, had provided the necessary basis of confidence between government and governed. There no longer exists, except in a few places such as Switzerland, that general acceptance of the conduct of national affairs that adds to the vigor of government and society alike.’1 These are the kinds of practical political problems to which the concept of political support, as found in systems analysis, has been directed.

The article compares different political systems with respect to one property: their capacity to produce policy change. I define the basic concept of the article, the ‘veto player’: veto players are individual or collective actors whose agreement (by majority rule for collective actors) is required for a change of the status quo. Two categories of veto players are identified in the article: institutional and partisan. Institutional veto players (president, chambers) exist in presidential systems while partisan veto players (parties) exist at least in parliamentary systems. Westminster systems, dominant party systems and single-party minority governments have only one veto player, while coalitions in parliamentary systems, presidential or federal systems have multiple veto players. The potential for policy change decreases with the number of veto players, the lack of congruence (dissimilarity of policy positions among veto players) and the cohesion (similarity of policy positions among the constituent units of each veto player) of these players. The veto player framework produces results different from existing theories in comparative politics, but congruent with existing empirical studies. In addition, it permits comparisons across different political and party systems. Finally, the veto player framework enables predictions about government instability (in parliamentary systems) or regime instability (in presidential systems); these predictions are supported by available evidence.

Since the 1960s, successive protest movements have challenged public policies, established modes of political participation and socio-economic institutions in advanced industrial democracies. Social scientists have responded by conducting case studies of such movements. Comparative analyses, particularly cross-national comparisons of social movements, however, remain rare, although opportunities abound to observe movements with similar objectives or forms of mobilization in diverse settings.

American elections depend substantially on the vitality of the national economy. Prosperity benefits candidates for the House of Representatives from the incumbent party (defined as the party that controls the presidency at the time of the election), whereas economic downturns enhance the electoral fortunes of opposition candidates. Short-term fluctuations in economic conditions also appear to affect the electorate's presidential choice, as well as the level of public approval conferred upon the president during his term. By this evidence, the political consequences of macroeconomic conditions are both pervasive and powerful. But just how do citizens know whether the incumbent party has succeeded or failed? What kinds of economic evidence do people weigh in their political appraisals? The purpose of our paper is to examine two contrasting depictions of individual citizens – one emphasizing the political significance of citizens' own economic predicaments, the other stressing the political importance of citizens' assessments of the nation's economic predicament – that might underlie the aggregate entwining of economics and politics. Ours is an inquiry into the political economy of individual citizens.

This article assesses the influence of material interests and cultural identities on European opinion about immigration. Analysis of respondents in twenty countries sampled in the 2002–03 European Social Survey demonstrates that they are unenthusiastic about high levels of immigration and typically overestimate the actual number of immigrants living in their country. At the individual level, cultural and national identity, economic interests and the level of information about immigration are all important predictors of attitudes. ‘Symbolic’ predispositions, such as preferences for cultural unity, have a stronger statistical effect than economic dissatisfaction. Variation across countries in both the level and the predictors of opposition to immigration are mostly unrelated to contextual factors cited in previous research, notably the amount of immigration into a country and the overall state of its economy. The ramifications of these findings for policy makers are discussed in the context of current debates about immigration and European integration.

This article provides a statistical analysis of core contentions of the ‘varieties of capitalism’ perspective on comparative capitalism. The authors construct indices to assess whether patterns of co-ordination in the OECD economies conform to the predictions of the theory and compare the correspondence of institutions across subspheres of the political economy. They test whether institutional complementarities occur across these subspheres by estimating the impact of complementarities in labour relations and corporate governance on growth rates. To assess the durability of varieties of capitalism, they report on the extent of institutional change in the 1980s and 1990s. Powerful interaction effects across institutions in the subspheres of the political economy must be considered if assessments of the economic impact of institutional reform in any one sphere are to be accurate.

As most political scientists know, the outcome of the American presidential election can be predicted within a few percentage points (in the popular vote), based on information available months before the election. Thus, the general campaign for president seems irrelevant to the outcome (except in very close elections), despite all the media coverage of campaign strategy. However, it is also well known that the pre-election opinion polls can vary wildly over the campaign, and this variation is generally attributed to events in the campaign. How can campaign events affect people's opinions on whom they plan to vote for, and yet not affect the outcome of the election? For that matter, why do voters consistently increase their support for a candidate during his nominating convention, even though the conventions are almost entirely predictable events whose effects can be rationally forecast?

In this exploratory study, we consider several intuitively appealing, but ultimately wrong, resolutions to this puzzle and discuss our current understanding of what causes opinion polls to fluctuate while reaching a predictable outcome. Our evidence is based on graphical presentation and analysis of over 67,000 individual-level responses from forty-nine commercial polls during the 1988 campaign and many other aggregate poll results from the 1952–92 campaigns.

We show that responses to pollsters during the campaign are not generally informed or even, in a sense we describe, ‘rational’. In contrast, voters decide, based on their enlightened preferences, as formed by the information they have learned during the campaign, as well as basic political cues such as ideology and party identification, which candidate to support eventually. We cannot prove this conclusion, but we do show that it is consistent with the aggregate forecasts and individual-level opinion poll responses. Based on the enlightened preferences hypothesis, we conclude that the news media have an important effect on the outcome of presidential elections – not through misleading advertisements, sound bites, or spin doctors, but rather by conveying candidates' positions on important issues.

Variance in how citizens interact with the political world constitutes one of many classes of individual difference. Understanding the antecedents of this variance is the central objective for students of political behaviour, and researchers draw on numerous factors in addressing this task. Unfortunately, one potentially vital factor, personality, has received only sporadic attention in recent decades. Neglect of personality was understandable for many years, as psychological research on personality failed to produce concise taxonomies applicable to the study of politics. As the present analysis demonstrates, however, this situation has changed. Research on personality has gained new footing with the emergence of a series of five-factor models, and these frameworks hold great potential for the study of political behaviour. This thesis is advanced in a two-part analysis. First, we outline how and why our understanding of citizen politics may be improved through application of five-factor models of personality. In doing so, we focus on the components of one specific taxonomy, the Big Five lexical model. Secondly, using three datasets, we explore the link between the Big Five personality factors and a wide array of political attitudes and behaviours. Results reveal that all facets of personality captured by the Big Five framework matter for citizen politics, and that personality effects operate on virtually all aspects of political behaviour. These findings demonstrate the insight that can emerge with further application of broad-scale models of personality.

This article presents the results of the first Deliberative Poll, in which a national British sample discussed the issue of rising crime and what to do about it. We describe Deliberative Polling and its rationale, the representativeness of the deliberative sample, the extent to which the participants acquired factual information about the issue and about politics generally, and how much and how they changed their views. We also weigh the extent to which such changes of view hinge on small group influences versus information gains.

Comparable survey data from Norway, Sweden and the United States are used to examine trends in political trust for the period 1964–86. During the early part of that period trust declined in all three countries; later it recovered for Norway but continued to plummet in Sweden and the United States. Three major features of the party system are hypothesized to explain the difference in these trends for the three countries. These features are: the structural aspects of the party system; the public's cognitive judgements of the parties as representatives of the policy interests; and the possibility that a negative rejection of political parties as undesirable institutions may spill over to citizen evaluations of government more generally.

Why is government corruption more pervasive in some societies than in others? In this article we examine public choice explanations that attribute corruption to a lack of competition in either political or economic arenas or both. The principal part of our analysis draws on recently-published data about levels of corruption for a broad cross-section of countries reported for the early 1980s. We supplement this with an additional analysis of a second dataset on corruption measured during the late 1980s. Our analyses confirm that political competition affects level of corruption, but this effect is nonlinear. Corruption is typically lower in dictatorships than in countries that have partially democratized. But once past a threshold, democratic practices inhibit corruption. However, we obtained mixed results with respect to the relationship of economic competition and corruption: government size does not systematically affect corruption, but membership of the Oil Producing and Exporting Countries (OPEC) does. Finally, corruption is more pervasive in low-income countries which tend to underpay public sector employees.

Electoral rules and constitutional structures can influence the level of political corruption. We show that proportional representation (PR) systems are more susceptible to corrupt political rent-seeking than plurality systems. We argue that this result depends on the different loci of rents in PR and plurality systems, and on the monitoring difficulties faced by both voters and opposition parties under PR. We also examine the interaction between electoral rules and presidentialism. We test our main predictions and interaction effects on a cross-section of up to ninety-four democracies. The empirical findings strongly support our hypothesis that PR systems, especially together with presidentialism, are associated with higher levels of corrupt political rent-seeking.

This article explores belief in political rumors surrounding the health care reforms enacted by Congress in 2010. Refuting rumors with statements from unlikely sources can, under certain circumstances, increase the willingness of citizens to reject rumors regardless of their own political predilections. Such source credibility effects, while well known in the political persuasion literature, have not been applied to the study of rumor. Though source credibility appears to be an effective tool for debunking political rumors, risks remain. Drawing upon research from psychology on ‘fluency’ – the ease of information recall – this article argues that rumors acquire power through familiarity. Attempting to quash rumors through direct refutation may facilitate their diffusion by increasing fluency. The empirical results find that merely repeating a rumor increases its power.

Over the past fifty years, top political science journals have published hundreds of articles about policy diffusion. This article reports on network analyses of how the ideas and approaches in these articles have spread both within and across the subfields of American politics, comparative politics and international relations. Then, based on a survey of the literature, the who, what, when, where, how and why of policy diffusion are addressed in order to identify and assess some of the main contributions and omissions in current scholarship. It is argued that studies of diffusion would benefit from paying more attention to developments in other subfields and from taking a more systematic approach to tackling the questions of when and how policy diffusion takes place.

Political parties are prominent in legislative politics and legislative research. Using data from the 99th Congress, this article assesses the degree to which significant party behaviour – defined and operationalized as behaviour that is independent of preferences – occurs in two key stages of legislative organization: the formation of standing committees and the appointment of conferees. Four hypotheses are developed and tested. When controlling for preferences and other hypothesized effects, positive and significant party effects are rare. A discussion addresses some criticisms of this unorthodox approach and attempts to reconcile some differences between these and previous findings.

This article considers how parties can decide on policy when there is no reliable information about the effect of these decisions on voting. Where this is the case they must base their stands on a priori assumptions about appropriate priorities, namely on political ideologies. These indicate the general policy area a party should occupy, but do not give detailed guidance on which position to take within it. Five different ways of deciding on this, within ideological constraints, are specified. The predictions derived from these models well anticipate the actual decisions made by post-war parties in twenty democracies, as summarized in the unique spatial maps of policy movements published by the Manifesto Research Group of the European Consortium for Political Research.

Previous research explains the evolution of parties' ideological positions in terms of decision rules that stress the uncertainty of the political environment. The authors extend this research by examining whether parties adjust their ideologies in response to two possible influences: shifts in public opinion, and past election results. Their empirical analyses, which are based on the Comparative Manifesto Project's codings of parties' post-war programmes in eight West European nations, suggest that parties respond to shifts in public opinion, but that these effects are only significant in situations where public opinion is clearly shifting away from the party's policy positions. By contrast, no evidence is found here that parties adjust their ideologies in response to past election results. These findings have important implications for parties' election strategies and for models of political representation.

Recent findings show an apparent erosion in the United States over the post-war years of ‘social capital’ understood as the propensity of individuals to associate together on a regular basis, to trust one another, and to engage in community affairs. This article examines the British case for similar trends, finding no equivalent erosion. It proposes explanations for the resilience of social capital in Britain, rooted in educational reform, the transformation of the class structure, and government policy. It concludes by drawing some general lessons from the British case that stress the importance of the distributive dimensions of social capital and the impact that governments can have on it.
