I consider the decision of a parliament that might change the electoral system for the forthcoming elections from plurality rule to proportional representation. Parties are o¢ ce-motivated. They care about winning and about the share of seats obtained. I consider two di¤erent scenarios of how...

The top-two primary is the new primary system passed in several states of the US that creates a single ballot in which the top two vote getters pass to the general election. Primary elections induce a sequential game with three stages: the candidate-entry stage, the primary election stage, and...

We propose a model in which different types of journalists have superior information to a newspaper's editor. Journalists compete for having their report published, but when writing their reports, they are uncertain about the preferences of the editor. We analyze the effects of competition and...

This paper analyzes the political economy of income redistribution when voters are concerned about fairness in tax compliance. We consider a two stage-model where there is a two-party competition over the tax rate and over the intensity of the tax enforcement policy in the first stage, and...

We model an election between two downsian candidates and a third deterministic one. There is uncertainty about the state of the world. Candidates receive signals on the state and propose a policy to implement. There are two types of voters: social concerned and biased. For both the cases in...

I analyze a model of electoral competition in which a candidate?s reputation and his need of cred- ibility restricts his policy choice to a certain subset of the policy space, its ideology set. Candidates are o¢ ce-motivated. They care about winning and also about the share of votes they get. I...
