Mixed-member proportional electoral systems – the best of both worlds?

Mixed electoral systems are often associated with the hope of combining proportional election outcomes with a concentrated party system, and thus achieving the best of both worlds in electoral system design. It is especially the mixed-member proportional (MMP) variant that has retained a good reputation in this regard. Via a comparative analysis, we analyze whether or not the general praise for MMP systems is corroborated empirically. Our results show that the performance of MMP systems is heavily influenced by technical details, and elections conducted under MMP vary broadly with regard to possible proportionality–concentration combinations.     

Political knowledge about electoral rules: Comparing mixed member proportional systems in Germany and New Zealand

Mixed Member Proportional (MMP) electoral systems are considered by some to be “the best of both worlds” because they combine single member district representation with proportional outcomes. Critics, however, maintain that such systems cause voter confusion leading some voters to cast misinformed votes. Survey data from Germany and New Zealand are used to investigate voter's political knowledge of the electoral system and their voting behavior. The findings suggest that knowledge about the electoral system is similar in New Zealand and in Germany. Although some may very well find the system complex, there is no evidence to suggest that a lack of knowledge about the electoral system influences voting behavior. The results undermine the claims made by skeptics who fear that misunderstanding threatens the legitimacy of electoral outcomes.     

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.     

An Opposing View of Scotland's Ballot Paper Problem: Arbuthnott and the Government had the Right Idea

The May 2007 Scottish Parliament election used a different ballot format from the one used in the previous elections, one that combined the regional and constituency votes onto one ballot paper (two separate papers were used before). Because there were many more invalid votes in 2007, the problem was blamed on the two‐vote ballot paper, which was recommended by the Arbuthnott Commission to prevent misunderstandings about what the two votes were for. Other places that use the mixed‐member proportional (MMP) electoral system tend to use a two‐vote ballot paper, with Germany and New Zealand seeing low levels of invalid votes. While the decision to revert to two separate papers in future Scottish Parliament elections might reduce the number of invalid votes, the price could be more confusion about the proportional nature of the electoral system unless public education improves significantly.     

Conditional political budget cycles: a review of recent evidence

Until recently, most research on political budget cycles was based on the (often implicit) presumption that these cycles do not differ across countries. However, more recent studies focus on heterogeneity. This paper surveys studies examining the factors conditioning the occurrence and strength of manipulation of fiscal policy for electoral purposes, at the aggregate level or at the level of a particular type of government expenditure. Conditioning factors discussed include: the level of development, institutional quality, age and level of democracy, electoral rules and form of government, transparency of the political process, the presence of checks and balances, and fiscal rules.     

Electoral reform in New Zealand: The report of the Royal Commission

In late 1986 the Royal Commission on the Electoral System in New Zealand published its report. The Commission's recommendations were both radical and comprehensive. Amongst other things it proposed the introduction of a mixed member proportional (MMP) electoral system, the abolition of the four Maori seats, a substantial increase in the number of MPs, the state funding of political parties, and various changes to the system of boundary redistribution and the administration of elections. This paper outlines the background to the establishment of the Royal Commission, briefly examines the Commission's principal findings, and considers the prospects for reform.     

Balancing district and party seats: The arithmetic of mixed-member proportional electoral systems

Mixed-member proportional electoral systems (MMP) are widely praised because they combine the direct, personal election of MPs from single-seat constituencies with a proportional seat allocation. However, the size of the proportional tier matters for the question of whether the system's overall proportionality is preserved. Hence, a key challenge for constitution-makers and scholars is finding the right balance between district and proportional seats, so as to maximise district representation and guarantee proportional representation.This paper develops the first theoretical model that helps to locate this sweet spot for district and party seats. The novel solution builds on Taagepera's “logical models” about party sizes. The model is tested on 58 national parliamentary elections under MMP rules.     

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.     

Making rules credible: divided government and political budget cycles

Political budget cycles (PBCs) can result from the credibility problems office-motivated incumbents face under asymmetric information, due to the temptation to manipulate fiscal policy to increase their electoral chances. We analyze the role of rules that limit public debt, because borrowing is a necessary condition for aggregate PBCs. Since the legislature must typically authorize new debt, divided government can make these fiscal rules credible. Commitment is undermined by either unified government or imperfect compliance with the budget law, which can help explain why PBCs are stronger in developing countries and in new democracies. When divided government affects efficiency, voters must trade off electoral distortions and government competence.     

District magnitude,electoral formula,and the number of parties

Abstract. Duverger's propositions concerning the psychological and mechanical consequences of electoral rules have previously been examined mainly through the lens of district magnitude, comparing the properties of single–member district plurality elections with those of multimember proportional representation elections. The empirical consequences of multimember plurality (MMP) rules, on the other hand, have received scant attention. Theory suggests that the effect of district magnitude on the number and concentration of parties will differ with regard to whether the allocation rules are plurality–based or proportional. I test this theory by drawing on a uniquely large–sample dataset where district magnitude and electoral formula vary but the basic universe of political parties is held constant, applying regression analysis to data from several thousand Hungarian local bodies elected in 1994 consisting of municipal councils, county councils, and mayors. The results indicate that omitting the variable of electoral formula has the potential to cause significant bias in estimates of Duvergerian consequences of district magnitude. In addition, the analysis of multi–member plurality elections from the local election dataset reveals counter–intuitively that candidate and party entry may increase with district magnitude under MMP, suggesting important directions for future investigation of MMP rules.     

The servant of two masters: Electoral incentives in the Scottish Parliament

Scholars have pointed out the potential impact of different electoral systems on the incentives for representatives to cultivate personal versus party reputations. The mixed-member proportional system (MMP) allows us to examine the effects of electoral systems on legislators’ incentives. Scholars have argued that MMP may be the ‘best of both worlds’; however, MMP may lead to competing demands on list representatives if they are also allowed to run as constituency candidates, as happens in the Scottish Parliament. I show that this leads to different levels of committee activity—which I use as a surrogate for party activity—from constituency Members of Scottish Parliament (MSPs), pure-list MSPs (who are elected via the party list and do not run in constituencies), and dual-candidate list MSPs (list MSPs who also run in constituencies), and that the proximity of elections also affects committee activity for those who run in constituencies.     

Proportional representation and attitudes about politics: results from New Zealand

PR systems often are credited with producing more equitable outcomes between political parties and encouraging wider social group representation than majoritarian systems. Theory suggests that this should instill greater trust, efficacy, and faith in the political system. We assume that citizens disadvantaged by majoritarian rules (political minorities) will have a relatively greater shift toward positive attitudes about democracy following a transition from a majoritarian system to proportional representation. We employ panel data from the 1993–1996 New Zealand Election Study (NZES) to test hypotheses about the effects of electoral system change on attitudes about governmental responsiveness, trust in government, and political efficacy. We find that there is a general shift in mass opinion toward more positive attitudes on some measures of efficacy and responsiveness. Political minorities display a greater shift toward feelings of efficacy than other voters.     

The demise of the last westminster system? Comments on the report of New Zealand's Royal Commission on the Electoral System

The New Zealand government set up a Royal Commission to consider the country's electoral system. It produced an unexpectedly radical Report, challenging some of the basic assumptions of the Westminster system under which New Zealand has been governed for 100 years. This article considers the wider implications of the Report, criticizing some of its assumptions, but accepting its basic analysis—a general philosophical dislike of the principle of concentrating power in the hands of the majority. It also explores the Report's treatment of alternative forms of proportional representation.     

Perceptions of Fairness and Support for Proportional Representation

This paper explores the causes and consequences of evaluations of the political system and support for electoral system change. In 1993, New Zealand voters adopted a referendum that fundamentally changed the way representatives are elected, moving from a plurality to a proportional (PR) electoral system. We examine the role of cynicism about the political system in adopting PR and how electoral change may shape evaluations of the political system. We expect that political minorities and those dissatisfied with the current performance of government are more likely to be cynical about the fairness of the political process and that these evaluations are related to support for PR. In turn, supporters of the referendum should judge the political system more favorably once the reform is implemented. Using panel data from the 1993 and 1996 New Zealand Election Studies, we find that support for PR is based on more general evaluations of the fairness of the political system and partisan self-interest. Those who supported PR and are politically aware are also more likely to have an increase in favorable evaluations of the political system.     

Political parties, electoral systems and democracy: A cross-national analysis

Abstract.  The number of political parties and the type of electoral system may impact the level of democratic functioning within a government. Models are used to explore whether the number of political parties increases a country's democracy score on the POLITY IV measure of democracy, and whether countries with proportional representation electoral systems have higher democracy scores than those without. Multiple regression analysis reveals that countries with proportional electoral systems have higher democracy scores. Countries involved in the Third Wave of democracy may find the choice of an electoral system among the most important issues in structuring a democratic government.     

The Impact of Electoral Reform on the Public Service: The New Zealand Case

October 1996 marked the beginning of a new era in New Zealand politics, with the advent of a system of proportional representation based on the German model. This article explores the impact of electoral reform on the public service. First, it summarises the extensive public sector reforms during the mid-to-late 1980s and considers the preparations undertaken by the public service for proportional representation. Second, it outlines the concerns and expectations about the likely consequences of the new electoral system on the bureaucracy. Third, against this background, the article examines the extent to which the public service has been affected by electoral reform. It is argued that despite some notable changes to the political environment within which officials operate, the overall impact of proportional representation on the public service to date has been modest. The analysis presented here is based on a series of interviews conducted during 1997 with ministers, senior public servants, ministerial advisers and parliamentary officials, along with a range of secondary sources.     

Ideological congruence over government mandates under majoritarian and proportional representation electoral systems

The existing literature on ideological congruence has typically looked at congruence immediately after elections when governments are formed. This article goes beyond that comparative static approach by examining changes in citizen-government ideological congruence between two fixed points in time, namely at the beginning and end of government mandates. Building on a veto player approach and dynamics of party competition under majoritarian and proportional representation (PR) electoral systems, the results indicate, first, that government positions are more stable in between elections, as the number of parties and their ideological distance increase in cabinet. Second, it appears that single-party and homogeneous coalition governments decrease ideological congruence between elections under low levels of polarisation, while they increase congruence under very high levels of polarisation. Third, it was found that governments under majoritarian systems slightly decrease congruence between elections while congruence stays stable on average under PR systems. The different levels of party system polarisation across majoritarian and PR electoral systems mostly explain this difference.     

Coalition government and satisfaction with democracy: An analysis of New Zealand's reaction to proportional representation

Following approval of a referendum in 1993, New Zealand replaced its first–past–the–post electoral system with proportional representation (PR). Although support for PR was initially high, less than a third expressed support for the new system a year and a half after its implementation. We examine two explanations for this decline. One theory assumes that dissatisfaction with the new system is the result of a growing alienation with politics, exacerbated by an unpopular coalition government that voters neither expected nor desired. Another theory assumes that evaluations of the new system are mediated by a preference for coalition or single party government. Our results indicate that a preference for single party government, guided primarily by partisan self–interest, has the largest impact. Nevertheless, negative evaluations of the performance of the coalition government helped contribute to a loss in support for PR suggesting that government performance can affect citizen's evaluation of political institutions, particularly when systems undergo radical change.

Executive Authority, the Personal Vote, and Budget Discipline in Latin American and Caribbean Countries

Recent scholarship on budgeting in Latin American and Caribbean (LAC) countries indicates that political institutions impact the level of budget discipline. Building upon this previous research, we argue that the principal problem that must be addressed in both the government and the legislature to insure strong fiscal discipline is the common pool resource (CPR) problem. At the cabinet level, the CPR problem arises because ministers consider the implications of decisions on their ministries only. The level of the CPR problem in the legislature depends upon the electoral system. Using a data set of LAC countries for the period 1988–97, we find that executive power in the budget process is most effective in reducing budget deficits when electoral incentives for the personal vote is high in the legislature, while strengthening the president (or prime minister) in countries where the personal vote is low in the legislature has no effect .
