Entrusting the power to punish to a central authority is a hallmark of civilization. We study a collective action dilemma in which self-interest should produce a sub-optimal outcome absent sanctions for non-cooperation. We then test experimentally whether subjects make the theoretically optimal...

Affirmative action rules are often implemented to promote women on labor markets. Little is known, however, about how and whether such rules emerge endogenously in groups of potentially affected subjects. We experimentally investigate whether subjects vote for affirmative action rules, against,...

We examine determinants of immigration requirements in a public goods game experiment with endogenous groups. Initially, the game consists of in-group players who enjoy an existing public good and out-group players who may subsequently enter the group. Motivated by different current migration...

We study the effect of voting when insiders ́public goods provision may affect passive outsiders. Without voting insiders ́contributions do not differ, regardless of whether outsiders are positively or negatively affected or even unaffected. Voting on the recommended contribution level...

This study investigates the degree to which framing and context influence observed rates of free-riding behavior in a negative externality laboratory experiment. Building on the work of Andreoni (1995a) and Messer et al. (2007) we frame the decision not to contribute to a public fund as...

I conduct an experiment to assess whether majority voting on a non- binding sharing norm affects subsequent behavior in a dictator game. In a baseline treatment, subjects play a one shot dictator game. In a voting treatment, subjects are ï¬rst placed behind a 'veil of ignorance' and vote on...
