The generic alliance game considers players in an alliance who fight against an external enemy. After victory, the alliance may break up, and its members fight against each other about the spoils of the victory. Our experimental analysis of this game shows: In-group solidarity vanishes after the...

In the light of violent clashes between Kyrgyz and ethnic Uzbeks in Kyrgyzstan in June 2010 we investigate the association between economic welfare and ethnicity in this country. We intend to answer two questions. First, are Uzbek households better off than Kyrgyz households, as is often claimed...

What is the optimal size of expert committees? To address this question, I present a model of a committee of experts with career concerns. Each expert may observe an argument about the state of the world and is unsure about the argument s soundness. Experts may remain silent or compete for the...

We examine lobby influence on policy outcomes in a legislative vote-buying model with two competing lobbyists and endogenous policy proposals.

We analyze the provision of a step-level public good in an experiment. Specifically, we investigate how the order of moves and the introduction of a second step-level affects public-good provision. We find that the sequential-move game improves public-good provision and payoffs. An additional...

In using their citizen candidate framework, Besley and Coate (2001) fi nd that if citizen candidates with sufficiently extreme preferences are available, lobbying has no in fluence on equilibrium policy. I show that this result does not hold in a model with ideological parties instead of citizen...

We investigate whether peer punishment is an efficient mechanism for enforcing cooperation in an experiment with a long time horizon. Previous evidence suggests that the costs of peer punishment can be outweighed by the benefits of higher cooperation, if (i) there is a sufficiently long time...

Which decision rule should we use to make a binary collective choice? While voting procedures are applied ubiquitously, they are criticized for being inefficient. Using monetary transfers, efficient choices can be made at the cost of a budget imbalance. Is it optimal to do so? And why are...
