TL;DR: In this paper, the authors present a survey of the literature on policy diffusion, focusing on the who, what, when, where, how and why of policy diffusion. But they do not discuss the main contributions and omissions in current scholarship.
Abstract: 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.

TL;DR: The authors discusses recent research on party politics and the welfare state that differs from traditional "partisan politics theory" that states that left-wing and right-wing parties hold contrasting positions on welfare issues, depending on the interests of their respective electorates.
Abstract: This article discusses recent research on party politics and the welfare state that differs from traditional ‘partisan politics theory’. The traditional approach states that left-wing and right-wing parties hold contrasting positions on welfare issues, depending on the interests of their respective electorates. This view has recently been challenged by three strands of research, which emphasize (1) the effects of electoral change on parties’ policy positions, (2) the role of context, notably electoral institutions, party competition and the configuration of party systems, and (3) the impact of different linkages between parties and electorates (particularistic versus programmatic). The implications of these arguments for the applicability of partisan theory are presented, and theoretical and empirical issues are identified for further research.

TL;DR: In this article, the authors demonstrate that naming and shaming is associated with improved human rights outcomes in autocracies, but with either no effect or a worsening of outcomes in democracies and hybrid regimes.
Abstract: Does naming and shaming states affect respect for human rights in those states? This article argues that incentives to change repressive behaviour when facing international condemnation vary across regime types. In democracies and hybrid regimes – which combine democratic and authoritarian elements – opposition parties and relatively free presses paradoxically make rulers less likely to change behaviour when facing international criticism. In contrast, autocracies, which lack these domestic sources of information on abuses, are more sensitive to international shaming. Using data on naming and shaming taken from Western press reports and Amnesty International, the authors demonstrate that naming and shaming is associated with improved human rights outcomes in autocracies, but with either no effect or a worsening of outcomes in democracies and hybrid regimes.

TL;DR: In this article, the authors examine whether exposure to public versus commercial news influences the knowledge citizens possess about current affairs, both domestically and internationally, and test, using propensity score analysis, whether there is variation across public service broadcasters in this regard.
Abstract: Public service broadcasters (PSBs) are a central part of national news media landscapes. In many countries, PSBs are the first choice of citizens when it comes to news providers. And in perhaps more countries still, PSBs are thought of as specialists in provision of hard news. We test this proposition here using survey data from a large crossnational survey involving indicators of current affairs knowledge and media consumption. Specifically, we examine whether exposure to public versus commercial news influences the knowledge citizens possess about current affairs, both domestically and internationally. We also test, using propensity score analysis, whether there is variation across PSBs in this regard. Results indicate that compared to commercial news, watching PSB has a net positive influence on knowledge of hard news, though not all PSBs are equally effective in contributing to knowledge acquisition. This knowledge gap between PSB and commercial news media consumption appears to be mitigated by factors such as de jure independence,proportion of public financing, and audience share.

TL;DR: The authors explored two other dimensions of economic voting, position and patrimony, and estimated their impact on vote intention, using a carefully specified system of equations, revealing a "compleat" economic voter who wields considerable power over electoral choice in Britain.
Abstract: Almost all the prolific work done on economic voting has been based on the classic reward–punishment model, which treats the economy as a valence issue. The economy is a valence issue, but it is much more than that. This article explores two other dimensions of economic voting – position and patrimony. Investigating a 2010 British survey containing relevant measures on these three dimensions, the authors estimate their impact on vote intention, using a carefully specified system of equations. According to the evidence reported, each dimension of economic voting has its own independent effect. Moreover, together, they reveal a ‘compleat’ economic voter, who wields considerable power over electoral choice in Britain. This new result confirms and extends recent work on American and French elections.

TL;DR: In this article, the occurrence of natural disasters has little effect on protest or leader survival in large coalition systems such as democracies, but if large numbers of people die in these disasters, more protests occur and leader survival diminishes.
Abstract: Analyses of the occurrence of natural disasters show that in large coalition systems, such as democracies, their occurrence has little effect on protest or leader survival. However, if large numbers of people die in these disasters, more protests occur and leader survival diminishes. In contrast, for leaders in small coalition systems, the occurrence of disasters increases protests and reduces tenure, but the level of fatalities has little effect. The anticipation of these potential political effects accounts for why many more people die in disasters in small coalition systems than in large coalition systems.

TL;DR: In this paper, the authors conducted a survey of public employees in Bolivia, Brazil, and Chile to establish the link between state capacity and development and found that within-country, cross-agency diversity in capacity often overwhelms the variation encountered across public sectors considered in their entireties.
Abstract: Studies of the link between state capacity and development often utilize national-level governance indicators to explain fine-grained development outcomes. As capacity in some bureaucratic agencies matters more for these outcomes than capacity in others, this work proxies for capacity within the set of relevant agencies by using a measure of ‘mean’ capacity across all agencies in a polity. This practice is problematic for two reasons: (1) within-country, cross-agency diversity in capacity often overwhelms the variation encountered across public sectors considered in their entireties; (2) national-level reputations for capacity are not particularly informative about differences in capacity in functionally equivalent agencies in different countries. The article draws on the author's survey of public employees in Bolivia, Brazil and Chile to establish these points.

TL;DR: In this paper, the authors argue that the question of whether democracy is a requirement of justice or an instrument for realizing it depends on the background circumstances against which democracy is defended, and the conclusion is that theories of justice designed for our world should be centrally concerned with democracy.
Abstract: Is democracy a requirement of justice or an instrument for realizing it? This article argues that the correct answer to this question depends on the background circumstances against which democracy is defended. In the presence of thin reasonable disagreement about justice, we should value democracy only instrumentally (if at all); in the presence of thick reasonable disagreement about justice, we should value it also intrinsically, as a necessary demand of justice. Since the latter type of disagreement is pervasive in real-world politics, the conclusion is that theories of justice designed for our world should be centrally concerned with democracy.

TL;DR: For example, the authors analyzed district-level data from 6,745 single-member district election contests from 53 democratic countries to test the evidence for Duverger's Law and Hypothesis.
Abstract: In districts where only one seat is contested, the electoral formula (plurality or majority) should be a major determinant of the number of parties that receive votes. Specifically, plurality rule should generate two-party competition while other institutional arrangements should generate electoral fragmentation. Yet tests of these propositions using district-level data have focused on a limited number of cases; they rarely contrast different electoral systems and have reached mixed conclusions. This study analyses district-level data from 6,745 single-member district election contests from 53 democratic countries to test the evidence for Duverger's Law and Hypothesis. Double-ballot majoritarian systems have large numbers of candidates, as predicted, but while the average outcome under plurality rule is generally consistent with two-party competition, it is not perfectly so. The two largest parties typically dominate the districts (generally receiving more than 90 per cent of the vote), and there is very little support for parties finishing fourth or worse. Yet third-place parties do not completely disappear, and ethnic divisions shape party fragmentation levels, even under plurality rule. Finally, institutional rules that generate multiparty systems elsewhere in the country increase electoral fragmentation in single-member plurality districts.

TL;DR: In this article, the effect of government repression on terrorist group dynamics is examined using data on terrorist groups for the 1976-2006 period; support is found for these conjectures on the terrorist group duration and outcomes.
Abstract: The question of how coercive government policies affect the duration and outcome of terrorist campaigns has only recently started to attract scholarly interest. This article argues that the effect of repression on terrorist group dynamics is conditional on the country's regime type. Repression is expected to produce a backlash effect in democracies, subsequently lengthening the duration of terrorist organizations and lowering the probability of outcomes favourable to the government. In authoritarian regimes, however, coercive strategies are expected to deter groups’ engagement in terrorism, thus reducing the lifespan of terrorist groups and increasing the likelihood of government success. These hypotheses are examined using data on terrorist groups for the 1976–2006 period; support is found for these conjectures on terrorist group duration and outcomes.

TL;DR: A simple technique for imputing missing values in such situations, which is a variant of hot deck imputation, drawing from the conditional distribution of the variable with missing values to preserve the discrete measure of theVariable.
Abstract: Missing values are a frequent problem in empirical political science research. Surprisingly, there has been little attention to the match between the measurement of the missing values and the correcting algorithms used. While multiple imputation is a vast improvement over the deletion of cases with missing values, it is often ill suited for imputing highly non-granular discrete data. We develop a simple technique for imputing missing values in such situations, which is a variant of hot deck imputation, drawing from the conditional distribution of the variable with missing values to preserve the discrete measure of the variable. This method is tested against existing techniques using Monte Carlo analysis and then applied to real data on democratisation and modernisation theory. We provide software for our imputation technique in a free and easy-to-use package for the R statistical environment.

Journal ArticleDOI
TL;DR: In this paper, a social network-based theory about the ways that legislators' social relationships affect floor voting behavior is proposed, which is argued that legislators establish contacts with both political friends and enemies and use the information they receive from these contacts to increase their confidence in their own policy positions.
Abstract: The authors contribute to the existing literature on the determinants of legislative voting by offering a social network-based theory about the ways that legislators’ social relationships affect floor voting behaviour. It is argued that legislators establish contacts with both political friends and enemies, and that they use the information they receive from these contacts to increase their confidence in their own policy positions. Social contacts between political allies have greater value the more the two allies agree on policy issues, while social contacts between political adversaries have greater value the more the two adversaries disagree on policy issues. To test these propositions, we use social network analysis tools and demonstrate how to account for network dependence using a multilevel modelling approach.

Journal ArticleDOI
TL;DR: In this paper, the authors developed a theory of election fraud based on the candidates' loyalty networks as the agents manipulating the electoral process, which predicts that the relationship between violence and fraud follows an inverted U-shape and that loyalty networks of both incumbent and challenger react differently to the security situation on the ground.
Abstract: What explains local variation in electoral manipulation in countries with ongoing internal conflict? The theory of election fraud developed in this article relies on the candidates’ loyalty networks as the agents manipulating the electoral process It predicts (i) that the relationship between violence and fraud follows an inverted U-shape and (ii) that loyalty networks of both incumbent and challenger react differently to the security situation on the ground Disaggregated violence and election results data from the 2009 Afghanistan presidential election provide empirical results consistent with this theory Fraud is measured both by a forensic measure, and by using results from a visual inspection of a random sample of the ballot boxes The results align with the two predicted relationships, and are robust to other violence and fraud measures

Journal ArticleDOI
TL;DR: In this article, an agent-based model of coalition building in multilateral negotiations is presented, which demonstrates that consensual decisions may emerge as an unintended by-product of government representatives' desire to form blocking coalitions.
Abstract: Although qualified-majority voting is possible, member states in the Council of the European Union (EU) still adopt most policies by consensus. The agent-based model of coalition building in multilateral negotiations presented here addresses this puzzle. The model demonstrates that consensual decisions may emerge as an unintended by-product of government representatives’ desire to form blocking coalitions. A qualitative case study demonstrates the plausibility of the model's assumptions and resulting coalition-building dynamics. Moreover, a quantitative test shows that the model's predictions correspond closely to the observed consensus rates. Finally, computational experiments predict a positive effect of the voting threshold but no effect of increases in membership on winning coalition size, which has important practical implications for institutional design and enlargement policy.

TL;DR: In this article, a hierarchical item-response model of individual judges' votes is estimated in order to identify judges' locations along a one-dimensional policy space, and the model is found to be no better than a null model that predicts that every judge will vote with the majority with the same probability.
Abstract: Policy-sensitive models of judicial behaviour, whether attitudinal or strategic, have largely passed Britain by. This article argues that this neglect has been benign, because explanations of judicial decisions in terms of the positions of individual judges fare poorly in the British case. To support this argument, the non-unanimous opinions of British Law Lords between 1969 and 2009 are analysed. A hierarchical item-response model of individual judges’ votes is estimated in order to identify judges’ locations along a one-dimensional policy space. Such a model is found to be no better than a null model that predicts that every judge will vote with the majority with the same probability. Locations generated by the model do not represent judges’ political attitudes, only their propensity to dissent. Consequently, judges’ individual votes should not be used to describe them in political terms.

TL;DR: This paper analyzed the relationship between migrants' remittances and elections in their countries of origin, and argued that migrants' decisions to remit reflect their home countries' electoral calendars and political context.
Abstract: Elections, the defining feature of representative democracy, are generally considered domestic matters. However, elections are increasingly influenced by and conducted on the international stage, and migrants have become increasingly important political actors in home country elections. This article analyses the relationship between migrants’ remittances and elections in their countries of origin, and argues that migrants’ decisions to remit reflect their home countries’ electoral calendars and political context. An analysis of remittance flows to eighty-one developing countries, 1990–2005, provides systematic evidence for the existence of political remittance cycles. Remittances increase in election years, an effect that is larger the more contested the election and the poorer the home country, suggesting an understudied link between developing countries’ domestic politics and their citizens living abroad.

TL;DR: This paper studied the distribution of federal spending across U.S. states over the period 1978-2002 and found no evidence that the allocation of federal money to the states is distorted by strategic manipulation to win electoral support.
Abstract: This paper tests various hypotheses about distributive politics by studying the distribution of federal spending across U.S. states over the period 1978-2002. We improve on previous work by using survey data to measure the share of voters in each state that are Democrats, Republicans, and independents, or liberals, conservatives and moderates. We nd no evidence that the allocation of federal spending to the states is distorted by strategic manipulation to win electoral support. States with many swing voters are not advantaged compared to states with more loyal voters, nor do \battleground states" attract more federal funds. Spending appears to have little or no eect on voters’ choices, while partisanship and ideology have large eects.

Journal ArticleDOI
TL;DR: This article found that 25% of voters do not believe their ballot choices are kept secret and over 70% report sharing their vote choices with others, which supports the broader claim that the intended benefits of institutional rules may not be realized if people's perceptions of these rules differ from their formal characteristics.
Abstract: Do people believe the votes they cast are truly secret? Novel items added to a nationally representative survey show that 25 per cent of respondents report not believing their ballot choices are kept secret and over 70 per cent report sharing their vote choices with others. These findings suggest that standard models of candidate choice should account for the potential effects of doubts about ballot secrecy. Consistent with this view, regression analysis shows that social forces appear to have a greater effect on vote choices among people who doubt the formal secrecy of the ballot. This analysis supports the broader claim that the intended benefits of institutional rules may not be realized if people's perceptions of these rules differ from their formal characteristics.

Journal ArticleDOI
TL;DR: In this paper, voters hold coalitions of parties collectively responsible for their valence-related performances, such as how voters evaluate governing parties' competence in handling issues like the economy, crime and foreign policy crises.
Abstract: Adams and Merrill have developed a model of policy-seeking parties in a parliamentary democracy competing in a PR electoral system, in which party elites are uncertain about voters’ evaluations of the parties’ valence attributes such as competence, integrity and charisma. This article extends that model to situations where voters hold coalitions of parties collectively responsible for their valence-related performances, such as how voters evaluate governing parties’ competence in handling issues like the economy, crime and foreign policy crises. It may also be relevant to voters’ evaluations of proto-coalitions of opposition parties. Computations suggest the central substantive conclusions reported in Adams and Merrill extend to this generalized model, and that collective responsibility enhances coalition members’ incentives to converge to similar policy positions but depresses their prospects of achieving their policy objectives.

TL;DR: In this paper, a tipping point version of Vogel's "California Effect" was studied in the context of the diffusion of human rights practices, with strong empirical support for this threshold effect, provided that the average level of respect for human rights in importing countries is sufficiently high.
Abstract: Drawing on a panel of 136 countries over the period 1982–2004, we study a tipping point version of Vogel's ‘California Effect’ in the context of the diffusion of human rights practices. Because human rights practices are often deeply embedded in a society's customs and political institutions, we expect that a high level of pressure from the importing countries is needed to bring about changes in an exporting country's human rights records. We find strong empirical support for this threshold effect; provided that the average level of respect for human rights in importing countries is sufficiently high, trading relationships can operate as transmission belts for the diffusion of human rights practices from importing to exporting countries.

Journal ArticleDOI
TL;DR: The authors argue that the saliency of identities as cues to affinity and difference vary with the distribution of types in the system and that the tendency for states to form alliances based on certain affinities is best thought of as a variable, rather than as a constant.
Abstract: In international politics ‘friends’ co-ally. But friendship is relational and contextual. Countries are more likely to act on particular common interests if few other actors share that identity. In contrast, new cleavages are likely to emerge as an identity becomes ubiquitous. The tendency for states to form alliances based on certain affinities is thus best thought of as a variable, rather than as a constant. For example, in systems where democracies are scarce, democracies eagerly co-ally. As democracy becomes common, however, incentives binding democratic allies together weaken compared to other definitions of mutual interest. This argument, and the evidence we provide, suggest that the salience of identities as cues to affinity and difference vary with the distribution of types in the system.

Journal ArticleDOI
TL;DR: This paper explored the sensitivity of the KF measure to violations of its core assumptions through simulation experiments and used public opinion data to assess the degree to which consequential levels of violation occur in actual democratic systems.
Abstract: A large number of studies of ideological congruence, and of the effect of public opinion on policy outcomes more generally, have relied on the Kim-Fording (KF) measure of median voter opinion. This measure has the great virtue of being readily calculable – no direct measurement of voter opinion is required – but it rests on assumptions concerning party locations and voter behaviour that are unquestionably incorrect, at least some of the time. This article explores the sensitivity of the KF measure to violations of its core assumptions through simulation experiments. It then uses public opinion data to assess the degree to which consequential levels of violation occur in actual democratic systems. The article concludes with a discussion of what the KF median really measures and where it can – and cannot – be safely used.

Journal ArticleDOI
TL;DR: In this article, the influence of Protestant missionaries on male-female educational inequalities in colonial India was explored, showing that competition between religious and secular groups spurred missionaries to play a key role in the development of mass female schooling.
Abstract: This article explores the influence of Protestant missionaries on male–female educational inequalities in colonial India. Causal mechanisms drawn from the sociology and economics of religion highlight the importance of religious competition for the provision of public goods. Competition between religious and secular groups spurred missionaries to play a key role in the development of mass female schooling. A case study of Kerala illustrates this. The statistical analysis, with district-level datasets, covers colonial and post-colonial periods for most of India. Missionary effects are compared with those of British colonial rule, modernization, European presence, education expenditures, post-colonial democracy, Islam, caste and tribal status, and land tenure. Christian missionary activity is consistently associated with better female education outcomes in both the colonial and post-colonial periods.

Journal ArticleDOI
TL;DR: In this paper, the effect of contextual, textual and interpreter characteristics on the interpretability of constitutional documents was investigated, and it was found that the most important determinants of variance are not contextual (for example, era, language or culture), but textual.
Abstract: An implicit element of many theories of constitutional enforcement is the degree to which those subject to constitutional law can agree on what its provisions mean (call this constitutional interpretability). Unfortunately, there is little evidence on baseline levels of constitutional interpretability or the variance therein. This article seeks to fill this gap in the literature, by assessing the effect of contextual, textual and interpreter characteristics on the interpretability of constitutional documents. Constitutions are found to vary in their degree of interpretability. Surprisingly, however, the most important determinants of variance are not contextual (for example, era, language or culture), but textual. This result emphasizes the important role that constitutional drafters play in the implementation of their product.

Journal ArticleDOI
TL;DR: In this article, the authors investigate whether returns to policy investment guide political management and statecraft, and find that returns, risk profiles and the uncertainty in public signals influence the prioritization of policies.
Abstract: This article sets out and tests a theory of public policy investment – how democratic governments seek to enhance their chances of re-election by managing a portfolio of policy priorities for the public, analogous to the relationship between investment manager and client. Governments choose policies that yield returns the public values; and rebalance their policy priorities later to adjust risk and stabilize return. Do the public reward returns to policy capital or punish risky policy investments? The article investigates whether returns to policy investment guide political management and statecraft. Time-series analyses of risk and return in Britain 1971–2000 reveal that risk and return on government policy portfolios predict election outcomes, and that returns, risk profiles and the uncertainty in public signals influence the prioritization of policies.

Journal ArticleDOI
TL;DR: The authors argue that Gordon Brown's rewriting of the British monetary constitution in May 1997 constituted political manipulation in a Rikerian sense, and that the institutionalization of discipline enabled New Labour to achieve economic and political goals.
Abstract: This article combines theory and narrative to shed new light on the politics surrounding the making of central bank independence in contemporary Britain. Its central argument is that Gordon Brown's rewriting of the British monetary constitution in May 1997 constituted political manipulation in a Rikerian sense. The government removed a contentious issue from party politics in order to signal competence and enforce internal discipline. Building on Elster's constraint theory, the paper argues that Brown adopted a pre-commitment strategy aimed at binding others. The heresthetic move had dual consequences, both constraining and enabling. The institutionalization of discipline enabled New Labour to achieve economic and political goals. By revisiting the political rationality of precommitment, this article questions the dominant credibility story underlying the choice of economic institutions.

Journal ArticleDOI
TL;DR: In this article, the authors argue that national parties compete with each other in an attempt to upload their own policy positions to their Europarty, and their ability to succeed in these attempts depends on their legislative resources.
Abstract: While Europarties have received increasing attention in recent years, little is known about how they arrive at common policy positions, given their strong internal ideological heterogeneity. In order to explain position formation within Europarties, this article argues that national parties compete with each other in an attempt to upload their own policy positions to their Europarty. The article hypothesizes that their ability to succeed in these attempts depends on their legislative resources. The argument is tested by analysing position formation within the four major Europarties for all European Parliament elections between 1979 and 2004. The empirical results confirm that position choice is skewed towards parties with a large seat share, which has important implications for political representation in Europe.

Journal ArticleDOI
TL;DR: The authors found that incumbent representatives indeed move their constituents' opinions in a particular direction, and that representatives have a stronger impact on constituents who are more frequently exposed to their messages, while Republican representatives shift constituents’ opinions in the pro-Republican and conservative direction.
Abstract: Most research on political representation focuses on how citizens’ ideology and partisanship influence their support for political candidates – leaving the question of whether (and how) elected officials influence citizens’ positions on political issues open to debate. The hypothesis tested here – using a unique, quasi-experimental design with American National Election Study data between 1956 and 2004 – is that Democratic representatives shift the opinions of constituents in the pro-Democratic and liberal direction, while Republican representatives shift constituents’ opinions in the pro-Republican and conservative direction. The findings show that incumbent representatives indeed move their constituents’ opinions in a particular direction, and that representatives have a stronger impact on constituents who are more frequently exposed to their messages.

Journal ArticleDOI
TL;DR: In this paper, a new dataset of territorial dispute hot spots from 1960-1998 is used to test the argument that the likelihood of conflict and the observation of joint democracy tend to cluster regionally.
Abstract: The likelihood of conflict and the observation of joint democracy tend to cluster regionally. This article tests the argument that these clusters can be explained by regional variations in the stability of international borders using a new dataset of territorial dispute hot spots from 1960–1998. These hot spots identify spatial and temporal correlations in the territorial dispute data and therefore serve as close proxies for regional or neighbourhood instability. The addition of these hot spots also eliminates a common form of omitted variable bias – the spatial clustering of conflict – in international conflict models. These results confirm that joint democracy is only statistically significant as a predictor of fatal militarized interstate disputes in more peaceful neighbourhoods once territorial hot spots are jointly estimated. The interaction between joint democracy and regional instability confirms that the effects of regime type on continued conflict apply mostly to dyads in peaceful regions.

Journal ArticleDOI
TL;DR: This paper presented a model of individual-level politicization of policy preference, which draws on psychological and political explanations and posits that greater external political efficacy results in a stronger effect of political ideology on concrete policy preference.
Abstract: How does individual political efficacy affect the construction of policy preferences? This article presents a model of individual-level politicization of policy preference, which draws on psychological and political explanations and posits that greater external political efficacy results in a stronger effect of political ideology on concrete policy preference. Two empirical studies that test this hypothesis are reported: an original survey experiment conducted in Israel, and an analysis that relies on the 2002 wave of the European Social Survey. The empirical findings support the hypothesis. In contrast to the established conviction that no association exists between political efficacy and policy preferences, these findings reveal that external political efficacy has a polarizing effect on expressed policy preferences.
