Does a disadvantaged candidate always choose an extremist program? When does a less competent candidate have an incentive to move to extreme positions in order to differentiate himself from the more competent candidate? Recent works answer by the affirmative (Groseclose 1999, Ansolabehere and...

I investigate the impact of proportional representation (PR) and majoritarian rule (MR) on voter turnout and minority representation using theory and experiments. Numerous empirical studies have compared turnout across PR and MR. However, the empirical evidence is mixed. I show theoretically and...

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,...

In this survey, we investigate the general mechanisms underlying the political economy of attention and review their empirical relevance, in particular for electoral accountability. The focus is on exogenous or stimulus-driven attention that political actors try to win or divert when pursuing...

This paper studies the effects of power-concentrating institutions on the quality of political selection, i.e., the voters' capacity to identify and empower competent politicians. In our model, candidates are privately informed about their abilities and are driven by office rents as well as...

Do established parties change political institutions to disadvantage smaller, non-mainstream parties if the latters' electoral prospects improve? We study this question with a natural experiment from the German federal State of Hesse. The experiment is the abolishment of an explicit electoral...

We investigate the geographical concentration of representatives and the distribution of fiscal transfers both theoretically and empirically. We develop a model which predicts that funds to an area are positively correlated with the number of representatives residing in that area. Our empirical...

We suggest a model of electoral competition between two parties which is extended by a third player : mass media. The classical one-dimensional competition model is changed by introducing an issue-specific sensibility-coefficient and by allowing for non-voting. The winner is selected by majority...

In their pursuit of being elected, politicians might not provide their constituents with independent viewpoints, but just try to outguess popular opinion. Although rational voters see through such populism, candidates can not resist resorting to it when the spoils of office are too large. For an...
