The rational-voter model is often criticized on the grounds that two of its central predictions (the paradox of voting and Duverger's law) are at odds with reality. Recent theoretical advances suggest that these empirically unsound predictions might be an artifact of an assumption in those...

This paper both theoretically and experimentally studies the properties of plurality and approval voting when the majority is divided as a result of information imperfections. The minority backs a third alternative, which the majority views as strictly inferior. The majority thus faces two...

This paper compares the properties of three electoral systems when voters have imperfect information. Imperfect information blurs voter decisions and may divorce the electoral outcome from the true preferences of the electorate. The challenge for electoral design is therefore to translate the...

Ranking have become increasingly popular on markets for study programs, restaurants, wines, cars, etc. This paper analyses the welfare implication of such rankings. Consumers have to make a choice between two goods of unknown quality with exogenous presence or absence of an informative ranking....

Consider a group of agents whose goal is to reform the status quo if and only if this is Pareto improving. Agents have private information and may have common or private objectives, which creates a tension between information aggregation and minority protection. We propose a simple voting system...

Why are U.S. congressmen reluctant to support gun control regulations, despite the fact that most Americans are in favor of them? We argue that re-election motives can lead politicians to take a pro-gun stance against the interests of an apathetic majority of the electorate, but in line with the...

There is often a gap between the prescriptions of an "optimal" tax system and actual tax systems, some of which can be neither efficient economically nor efficient at redistributing income. With a focus on personal income taxes, this paper reviews the political economics literature on tax...

We present in this paper a bench-mark model for the optimal speed of transition from a state-owned to a private market economy, based on the consumption-savings decision in a closed economy. This bench-mark model abstracts from rigidities or frictions to focus on the macroeconomic conditions for...

Voting Theory generally concludes that, in first-past-the-post elections, all votes should go to effective candidates (Duverger’s Law), and parties should adopt a similar platform (Median Voter Theorem). Such predictions are not always met in practice, however. We show why divergence and vote...

We analyse how the governance structure of political parties influences electoral competition. Parties choose their organization to manipulate the incentives of politicians to provide effort. We show that intra- and inter-party competition interact to shape these incentives. We also get new...
