Voters often express support for a candidate whose policy platforms differ from their ideal policy preferences. We argue that under these circumstance acts of expressing support can causally change voters’ policy preferences. We conceptualize our arguments in a theoretical model of policy...

A conclave is a voting mechanism in which a committee selects an alternative by voting until a sufficient supermajority is reached. We study experimentally welfare properties of simple three-voter conclaves with privately known preferences over two outcomes and waiting costs. The resulting game...

Group-based identity undermines democracy by impeding democratic change of government. A substantial literature has therefore studied how to make democracy consistent with group identity. We contribute to this literature by introducing the role of group decisiveness into voting incentives and...

This paper analyses a model of electoral competition with lobbying, where candidates hold private information about their willingness to pander to lobbies, if elected. I show that this uncertainty induces risk-averse voters to choose candidates who implement policies biased in favor of the...

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...

In this chapter, we assess recent contributions of computational models to the study of politics. We focus primarily on agent-based models developed by economists and political scientists. These models address collective action problems, questions related to institutional design and performance,...
