We experimentally investigate information aggregation through majority voting when some voters are biased. In such situations, majority voting can have a "dark side", that is, result in groups making choices inferior to those made by individuals acting alone. In line with theoretical...

Whether individuals vote strategically is one of the most important questions at the intersection of economics and political science. Exploiting a aw in the German electoral system by which a party may gain seats by receiving fewer votes, this paper documents patterns of preference...

Experiments can be used to relax technical assumptions that are made by necessity in theoretical analysis, and further test the robustness of theoretical predictions. To illustrate this point we conduct a three-person bargaining experiment examining the effect of different decision rules...

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...

Weak electoral registration requirements are commonly thought to encourage electoral participation, but may also promote electoral fraud. For one, candidates and their supporters can more easily mobilize voters outside the district to register and vote for the candidates, even though these...

Enhanced deliberation has been prescribed as the way forward to improve democratic decision-making, while generating positive attributes like trust and legitimacy. Yet, we do not know to what extent different decision-making election rules affect the deliberative process and its outcome. This...

There are many situations in which different groups make collective decisions by committee voting, with each group represented by a single person. A natural question is what voting system such a committee should use. Concepts based on voting power provide guidelines for this choice. The two most...

In two laboratory surveys run in France during the 2014 European Elections, we asked the participants to provide their personal evaluations of the parties in terms of ideological proximity, and asked how they would vote under three proportional, closed-list voting rules: the (official)...
