We compare single round vs runoff elections under plurality rule, allowing for partly endogenous party formation. Under runoff elections, the number of political candidates is larger, but the influence of extremist voters on equilibrium policy and hence policy volatility are smaller, because the...

We consider a framework where the optimal decision rule determining the collective choice depends in a simple way on the decision makers' posterior probabilities of a particular state of nature. Nevertheless, voting is generally an inefficient way to make collective choices and this paper sheds...

This paper studies the impact of immigration on public policy setting. As a natural experiment, we exploit the sudden arrival of eight million forced migrants in West Germany after World War II. These migrants were on average poorer than the West German population, but unlike most international...

Economic and social interactions often take place in open communities but the dynamics of the community choice process and its impact on cooperation of its members are yet not well understood. We experimentally investigate community choice in social dilemmas. Participants repeatedly choose...

We show that an institutional change designed expressly to heighten competition for the provision of union services can have a substantial effect on unionization and employment relations. We study a French reform of 2008 that introduced mandatory elections for representation of workers at firm,...

We exploit a discontinuity in Brazilian municipal election rules to investigate whether political competition has a causal impact on policy choices. In municipalities with less than 200,000 voters mayors are elected with a plurality of the vote. In municipalities with more than 200,000 voters a...

Previous research has established that good-looking political candidates win more votes. We extend this line of research by examining differences between parties on the left and on the right of the political spectrum. Our study combines data on personal votes in real elections with a web survey...

Does voting have downstream consequences for turnout and political preferences? While research initially showed strong support for the notion that the experience of voting fosters civic habits and political engagement, recent work has cast doubt on how universal these patterns are. We contribute...

We study communication in committees selecting one of two alternatives when consensus is required and agents have private information about their preferences. Delaying the decision is costly, so a form of multiplayer war of attrition emerges. Waiting allows voters to express the intensity of...
