Is plurality or majority electoral reform a sensible option in Germany’s muddled electoral system debate? Yes, it is. Since Germany’s mixed-member proportional system fails to concentrate the party system in a sufficient way, Peggy Matauschek searches for a suitable alternative to the principle of proportional representation. She discusses the following options according to their contextual conditions: single-member plurality and majority electoral systems—like the alternative vote system—, parallel systems, proportional representation systems with a low district magnitude and majority bonus systems. In light of its balanced performance, the study advocates the introduction of a system with a majority bonus for a coalition.

We propose that leaders play a more important role in voters’ party sympathy in proportional representation systems (PR) than previous research has suggested. Voters, from the 2018 Swedish General Election, were in an experiment asked to describe leaders and parties with three indicative keywords. Statistical models were conducted on these text data to predict their vote choice. The results show that despite that the voters vote for a party, the descriptions of leaders predicted vote choice to a similar extent as descriptions of parties. However, the order of the questions mattered, so that the first questions were more predictive than the second question. These analyses indicate that voters tend to conflate characteristics of leaders with their parties during election campaigns, and that leaders are a more important aspect of voting under PR than previous literature has suggested. Overall, this suggests that statistical analysis of words sheds new light of underlying sympathies related to voting.

The Relationship

How do electoral rules shape the substantive representation of traditionally underrepresented groups? Using an original dataset of introduced and passed bills in the Korean National Assembly, which has both single-member districts and proportional representation, we examine the extent to which institutions condition the relationship between lawmaker gender and the substantive representation of women. While women lawmakers engage in higher levels of substantive representation of women, proportional representation allows both women and men to introduce more women’s issue bills than their counterparts elected through single-member districts. Furthermore, legislators elected through proportional representation are more effective at achieving passage of women’s issue legislation when compared with those elected in single-member districts, and this effect is especially pronounced for men. Our findings show that electoral systems matter for the representation of marginalized groups and that proportional representation systems allow both female and male politicians to increase their substantive representation of women.

Representation Systems

A paradox in the comparative literature on electoral systems is that one of the most common systems in Europe – flexible-list proportional representation systems – may be the least understood. Any study of flexible-list systems must start by acknowledging a puzzle: why candidates spend time and effort striving to win preference votes when typically these votes make no difference between election and defeat. Offering the first comprehensive multi-country test of this key puzzle, we provide evidence from Belgium, the Czech Republic, and Slovakia that parties will promote to better list ranks in the next election those candidates who are successful at winning preference votes, thereby improving their prospects of election in the longer term and incentivizing them to cultivate personal reputations. Our findings have important implications for party scholars and practitioners when designing, or reforming, political institutions.

Representation Systems

Spatial models of party competition constitute a recent and incrementally developing literature which seeks to explore the relationships between citizens' decisions and candidates' strategies. Despite the mathematical and deductive rigor of this approach, it is only now that political scientists can begin to see the incorporation of those considerations which less formal analyses identify as salient, and perhaps crucial, features of election contests.One such consideration concerns the candidates' objectives. Specifically, spatial analysis often confuses the distinction between candidates who maximize votes and candidates who maximize plurality. Downs and Garvey, for example, assume explicitly that candidates maximize votes, though plurality maximization is clearly the assumption which Garvey actually employs, while Downs frequently assumes that vote maximization, plurality maximization, and the goal of winning are equivalent. Downs, nevertheless, attempts to disentangle these objectives, observing that plurality maximization is the appropriate objective for candidates in a single-member district, while vote maximization is appropriate in proportional representation systems with many parties. All subsequent spatial analysis research, however, assumes either implicitly or explicitly that candidates maximize plurality. If Downs is correct, therefore, this research may not be relevant for a general understanding of electoral competition in diverse constitutional or historical circumstances. The question then is whether those strategies that maximize votes differ from those strategies that maximize plurality.

The Impact

Research on the impact of gender quotas in open-list proportional representation systems has described quotas as ineffective or even paradoxical. While some authors argue that gender quotas without a placement mandate will be essentially ineffective since most women will be nominated to unpromising positions, others suppose that women will be disadvantaged by gender quotas because the increase in the number of female candidates will decrease the average number of preferential votes cast for women. We reexamine the evidence for these claims by analyzing the case of Poland. We demonstrate that the gender quota introduced there in 2011 increased the number of women placed at promising ballot positions and had very little impact on the number of preferential votes cast for women. Additionally, using simulations, we show that the quota had a positive impact on the number of elected women.
