We use the citizen-candidate model to study the differential incentives that alternative voting rules provide for candidate entry, and their effect on policy polarization. In particular, we show that allowing voters to cast multiple votes leads to equilibria which support multiple candidate...

Does party polarization affect the electoral prospects of a new centrist candidate? The paper investigates this question in the context of a laboratory experiment where a centrist candidate is added to the race between a left candidate and a right candidate. The experimental design varies the...

Countries that elect their policy-makers by means of Plurality Voting tend to have a two-party system. We conduct laboratory experiments to study whether alternative voting procedures yield a two-party system as well. Plurality Voting is compared with Approval Voting and Dual Voting, both of...

Does party polarization affect the electoral prospects of a new centrist candidate? The paper investigates this question in the context of a laboratory experiment where a centrist candidate is added to the race, between a left candidate and a right candidate. The experimental design varies the...

We analyze the relative importance of party ideology and rents from office in the formation of coalitions in a parliamentary democracy. In equilibrium, the types of coalitions that are formed may be minimal winning, minority or surplus and they may be deologically 'disconnected'. The coalitions...

We study a game theoretic model of a parliamentary democracy under proportional representation where ideologically motivated citizen groups form parties, voting occurs and governments are formed. We study the coalition governments that emerge as functions of the parties' seat shares, the size of...
