Voter turnout and district-level competitiveness in mixed-member electoral systems

It has been suggested that one of the reasons why majoritarian electoral systems are associated with lower voter turnout in comparison to proportional electoral systems is that citizens in uncompetitive districts (“safe seats”) are not motivated to vote. This study brings this thesis into a new context and tests it with unique data. Mixed-member electoral systems have both majoritarian and proportional components. The relative importance of these components differs between mixed-member proportional (MMP) and mixed-member majoritarian (MMM) systems. I argue that, due to this difference, the impact of district-level competitiveness on turnout is stronger in MMM than in MMP. An analysis of district-level electoral data from four countries confirms this hypothesis. Findings from this study advance our theoretical understanding of voter participation and also of the functioning of mixed-member electoral systems.     

Mixed electoral rules’ impact on party systems

The growing literature about mixed electoral systems has addressed their effect on party systems, voting behavior, campaign strategies, legislative roll-call voting, and other issues in a handful of countries. But, the effect of mixed systems has not been fully evaluated cross-nationally or longitudinally. Using data from the World Bank’s Database of Political Institutions, we address this gap in the literature by investigating two related questions. First, do mixed electoral rules produce different election outcomes than other election rules? Second, are these results attenuated by the definitions of mixed systems that scholars employ? We find that mixed systems generate outcomes that are distinct from other electoral systems and that these findings are generally robust across different definitions.     

Electoral Volatility and Party Decline in Western Democracies: 1970–1995

In 1970, Richard Rose and Derek Urwin published a seminal piece on the stability of party support in Western democracies, 'Persistence and Change in Western Party Systems Since 1945'. Everywhere they looked, established parties seemed to reflect stability rather than change, lending credence to the notion that party systems were 'frozen'. Numerous subsequent studies, however, have produced mixed results. Part of what seems to be fueling this debate lies in the disparate measures researchers use to gauge stability. In this update of Rose and Urwin's study, I address the issue of comparable results by maintaining the same data source and methods they used to gauge the stability of party support, extending the study to the present. The results indicate that party system instability is on the rise throughout much of the West since 1970, with statistically significant increases seen in Scandinavia and across all regions combined. Furthermore, the parties which seem to be experiencing the most change are not only the newest parties – as the frozen cleavages thesis might predict – but also those parties formed during the interwar period, the large majority of which showed much greater stability in 1970.     

How electoral vulnerability affects pension politics: Introducing a concept,measure and empirical application

Are electorally vulnerable politicians really less likely to support controversial legislation, such as pension reforms? While the literature on welfare state retrenchment has increasingly pointed to the role of electoral factors in the dynamics of social policy cutbacks, there are few studies that actually measure the magnitude of electoral pressure and its consequent impact on the politics of reform. To this end, the authors have developed a quantitative measure of the electoral vulnerability of politicians and tested its impact on pension reform outcomes using an original dataset comprising 16 Western European countries from 1980 to 2003. In line with expectations, the results show that the impact of electoral vulnerability on reform depends upon the system of interest intermediation. In corporatist systems, electoral vulnerability indeed impedes reform. But in pluralist systems, increased electoral vulnerability is associated with higher levels of reform. This is because unions in corporatist (but not in pluralist) systems can exploit electoral vulnerability in pre‐legislative bargaining, and thus pressure politicians. Consequently, this study has broader implications for the differential responsiveness of democracies to redistributive issues more generally.     

It's Only Made Things Worse: A Critique of Electoral Reform in Britain

Since it came to power, New Labour has introduced a range of new electoral system into the British political system, implicitly accepting the argument that Britain's traditional electoral system - first-past-the-post (FPTP) - has been a cause of voter disenchantment with Britain's representative democracy. In this article, it is asserted that Labour's reforms have merely compounded this problem, while demonstrating that all electoral systems have significant flaws. Indeed, it is argued that the flaws of the new systems are more serious than those of FPTP and threaten an even greater disconnection between UK politicians and the people they represent."     

How do voters perceive ideological congruence? The effects of winning and losing under different electoral rules

The degree of ideological congruence between citizens and their elected representatives is an important feature of democratic systems of government. A long tradition of literature has examined the ideological linkages between citizens and governments, often drawing attention to the differences (or lack thereof) in congruence across different types of electoral systems. Previous research has largely relied on aggregate-level measures of ideological congruence, such as the ideological distance between the position of the median voter and the government. We turn our attention here to how congruence relationships are perceived by individual voters, and how the perceptions of congruence may vary across electoral system types. This individual-level measure of ideological congruence is important in that individual-level, rather than aggregate-level, congruence has been shown to influence other outcomes such as citizen satisfaction with democratic performance. We expect electoral “winners” – those who voted for a party that entered government – to perceive greater ideological congruence between themselves and the government compared to electoral “losers”. We expect this effect to be stronger in majoritarian systems where political competition takes place primarily between two parties, than in proportional systems where electoral losers are more likely to receive a proportional share of representation. We test these expectations by estimating random-effects regressions of perceived individual-level congruence using data from 54 elections held in 23 democracies included in the Comparative Study of Electoral Systems (CSES). The results provide consistent support for our expectations. Electoral winners in all types of electoral systems perceive greater ideological congruence between themselves and the government, and this effect is stronger in majoritarian systems.     

How electoral systems affect MPs’ positions

The question how different electoral systems affect the representation of voters in parliaments has been a thorny issue for a considerable time. While some research suggests that first-past-the-posts systems should lead to a closer correspondence between the preferences of the electoral district’s median voter and of its representative, other work concludes that in proportional representation (PR) systems, especially with open lists, candidates have an incentive to cultivate a strong personal vote.     

Income inequality,electoral systems and party polarisation

This study analyses why income inequality and party polarisation proceed together in some countries but not in others. By focusing on the relationship between income inequality, the permissiveness of electoral systems and party polarisation, the study offers a theoretical explanation for how the combination of income inequality and permissive electoral systems generates higher party polarisation. After analysing a cross‐national dataset of party polarisation, income inequality and electoral institutions covering 24 advanced democracies between 1960 and 2011, it is found that a simple correlation between income inequality and party polarisation is not strong. However, the empirical results indicate that greater income inequality under permissive electoral systems contributes to growing party polarisation, which suggests that parties only have diverging ideological platforms due to greater income inequality when electoral systems encourage their moves towards the extreme; parties do not diverge when electoral systems discourage their moves towards the extreme.     

Increasing irrationality? The equilibrium relationship between electoral and legislative party system size, 1950–2005

Institutional theories of party system size tell us that voters and parties should anticipate the mechanical effects of electoral systems and adjust their behaviour accordingly. If these expectations hold true, then the size of the party system at the electoral and legislative levels should maintain a long-run equilibrium relationship, as the number of parties receiving votes is adjusted in response to the number of parties in the legislature. I estimate a series of error-correction models to examine this expectation in 16 Western democracies from 1950 to 2005. Party system size at the electoral level does exhibit a general, equilibrium relationship with party system size in the legislature. However, this relationship has recently disappeared in single-member-district systems. This growing disparity between party system size at the electoral and legislative levels signals important changes in the nature of electoral representation.     

Disproportionality and voter turnout in new and old democracies

A long-standing puzzle in electoral research is why the disproportionality of electoral systems has a negative effect on voter participation in established democracies, but not in new democracies. We propose a learning theory of electoral system’s effects, and test it in a cross-national analysis and by using Spain as a case study. Electoral disproportionality is unrelated to voter participation in early elections after democratization, but the relationship is increasingly visible as democracies grow older. The case study uncovers two mechanisms: small parties optimize their mobilization strategy only after the first democratic elections, and the difference in the turnout rates of small party supporters and large party supporters grows over time. Time is needed before the consequences of electoral systems are fully revealed. Importantly, the findings suggest that studies carried out just after an electoral system is created or reformed may provide downward biased estimates of their long-term consequences.     

Party systems,electoral systems and constraints on corruption

This article explores the relationship between the party system, electoral formulas and corruption. Previous research has focused on the various incentives for political actors to monitor, or engage in corruption based on variations in the electoral formula. However, the electoral formula has mainly served as a proxy for the party system – whether multi-party or two-party. In this analysis, I test directly the relationship between party systems and corruption and in addition, add a degree of nuance to the established line of thinking within this literature. I argue that two-party systems in countries with predominantly single-member district (SMD) electoral formulas will demonstrate lower corruption on average than multi-party systems in SMD countries. However, I argue that this interaction effect does not play out in countries with proportional representation (PR). I test this hypothesis on 70 democratic and semi-democratic countries from 1987 to 2005 and find strong empirical support for the claim that multipartism in SMD countries is associated with higher levels of corruption, while the party system’s relationship with corruption plays no role in PR countries.     

A test of candidate equilibrium

Richard McKelvey predicts that candidates will converge to an equilibrium if candidates and voters maximize their utility and voters' preferences conform to stringent assumptions. Although there are discrepancies between electoral data and the requirements of the theory, an analysis of 1972 and 1976 survey data lends support to basic components of the theory. First, most voters did choose the candidate who provided the greater utility. Second, voter distribution was not asymmetrical enough to allow a candidate to win by moving away from the median toward a concentration of voters. Third, the winning strategy for a candidate was to locate at or near the median. While formal theories' predictions will not hold in their precisely stated form, the assumptions can be robust enough to offer an explanation of electoral choices.     

It's Parties That Choose Electoral Systems (or, Duverger's Laws Upside Down)

This article presents, discusses and tests the hypothesis that it is the number of parties that can explain the choice of electoral systems, rather than the other way around. Already-existing political parties tend to choose electoral systems that, rather than generate new party systems by themselves, will crystallize, consolidate or reinforce previously existing party configurations. A general model develops the argument and presents the concept of 'behavioral-institutional equilibrium' to account for the relation between electoral systems and party systems. The most comprehensive dataset and test of these notions to date, encompassing 219 elections in 87 countries since the 19th century, are presented. The analysis gives strong support to the hypotheses that political party configurations dominated by a few parties tend to establish majority rule electoral systems, while multi-party systems already existed before the introduction of proportional representation. It also offers the new theoretical proposition that strategic party choice of electoral systems leads to a general trend toward proportional representation over time.     

Candidate-centred electoral systems and voter turnout

Abstract

This study evaluates contradictory theoretical predictions concerning the relationship between the candidate-centredness of electoral systems and voter turnout. Candidate-centredness has been proposed to both stimulate and depress turnout. Cross-sectional time-series data from 36 democracies between 1990 and 2014 are used to test the competing assumptions made about the impact of the personal vote on turnout. Three measures assessing the extent to which electoral systems create incentives to cultivate a personal vote are employed. The results show that turnout is the lowest in candidate-centred systems and the highest in party-centred systems with closed and ordered lists, while controlling for a host of contextual factors that have been linked to aggregate turnout. In addition, the finding that candidate-centredness is negatively related to turnout holds up even when taking into account district magnitude, electoral disproportionality and effective number of parties.     

Catalysts and barriers: Explaining electoral reform in Western Europe

Most accounts of electoral system change tend to consider it as being driven by purely partisan interests. Political parties are expected to change the electoral rules as a way to maximise gains or minimise losses. However, little work has been done on the question of why electoral reforms are so scarce in spite of these potential benefits. In this study, a wide range of both factors that may foster (‘catalysts’) and ones that may hinder (‘barriers’) the change of electoral institutions are investigated. A statistical analysis is performed of 16 West European countries from 1975 to 2005, covering 23 reforms of the proportionality of their electoral systems. It is found that procedural barriers are more effective for explaining the likelihood of electoral reforms than (most of) the catalysts. Additionally, there are indications that courts may play a more active role in triggering reform than previously thought.     

Preference votes without preference? Institutional effects on preference voting: an experiment

A classical question of political science is to what extent electoral systems influence voting behaviour. Yet, many of these studies examine how different electoral systems affect the election results in terms of vote distribution across parties. Instead, we investigate how electoral rules affect intra party preference voting. Given the importance of the debate on the personalization of politics, insight into how electoral rules shape intra-party choice is a valuable contribution to the literature. In our study, we focus on the effect of two specific rules: the option to cast a list vote and on a single versus multiple preference votes. The results of experiments conducted in Belgium and the Netherlands show that electoral rules indeed influence voting behaviour with regard to intra party preference voting, although differences exist between the Netherlands and Belgium. Moreover, we find that the option to cast a list vote equally affects votes for the first candidate on the list, as well as lower positioned candidates. This suggests that preference votes might be less preferential than has often been assumed.     

Voter preferences and party loyalty under cumulative voting: Political behaviour after electoral reform in Bremen and Hamburg

Many electoral systems constrain voters to one or two votes at election time. Reformers often see this as a failing because voters' preferences are both broader and more varied than the number of choices allowed. New electoral systems therefore often permit more preferences to be expressed. In this paper we examine what happens when cumulative voting is introduced in two German states. Even when we allow for tactical considerations, we find that the principle of unconstrained choice is not widely embraced by voters, although in practice, too, many seem to have preferences for more than just one party. This finding has implications for arguments relating to electoral reform as well as how to conceive of party affiliations in multi-party systems.     

The impact of the electoral system on post-communist party development: The case of the 1993 Russian parliamentary elections

This paper uses a case study of the 1993 Russian parliamentary elections to explore the influence of proportional representation and plurality electoral systems on party formation in a post-communist regime. The mixed PR-plurality electoral system used by Russia in the 1993 elections is a particularly useful case for such analysis for it allows the simultaneous study of these two electoral systems under the same set of social, economic, and cultural conditions. This study found that common emphasis placed on the number of parties allowed by PR versus plurality systems is misplaced in the context of Russian politics. The vital impact of electoral systems under post-communist conditions is their permeability to independent candidates. PR systems tend to impose party labels on the electorate and elites and thus bolster the status of parties as electoral agents. Plurality systems allow independents to compete on a level playing field with partisan candidates, robbing parties of the preferential treatment they need to get established in the initial years of democratic governance.     

The political consequences of the electoral system in the Republic of Ireland

The single transferable vote electoral system, popular with many electoral reformers, has been used for parliamentary elections in the Republic of Ireland since 1922. Examination of its impact shows that it has delivered as high a degree of proportionality as most PR systems despite the unavoidable use of relatively small district magnitudes. It has not produced either a fragmented party system or unstable governments. Critics have blamed it for contributing to a weak parliament, but these criticisms remain unproven. Suggestions are made for the wider use of STV, especially in countries currently employing preferential list systems.
