This paper investigates the effect of aggregate-level information shocks regarding support for a populist right-wing party on the individual disposition to report a respective political preference in survey interviews. Despite controversial debates about the social acceptability of its...

In this paper I study the strategic implications of coalition formation in an assembly. A coalition forms a voting bloc to coordinate the voting behavior of its members, acting as a single player and affecting the policy outcome. In a game of endogenous coalition formation, I show that voting...

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...

Informed voters are believed to be necessary for the well-functioning of elections. However, the puzzle is raised: Why are voters and politicians becoming more polarized despite the increased availability of information? We consider an election with policy-motivated candidates and partially...

Interest groups are introduced in a spatial model of electoral competition between two political parties. We show that, by coordinating voting behavior, these interest groups increase the winning set, which is defined as the set of policy platforms for the challenger that will defeat the...

A small committee has to approve/reject a project with uncertain return. Members have different preferences: some are value-maximizers, others are biased towards approval. We focus on the efficient use of scarce information when communication is not guaranteed, and we provide insights on the...

There are many situations in which different groups make collective decisions by committee voting, where each group is represented by a single person. Theoretical concepts suggest how the voting systems in such committees should be designed, but these abstract rules can usually not be...

This paper analyzes responsibility attributions for outcomes of collective decision making processes. In particular, we ask if decision makers are blamed for being pivotal if they implement an unpopular outcome in a sequential voting process. We conduct an experimental voting game in which...
