In this paper we show that a simple model of fairness preferences explains major experimental regularities of common pool resource (CPR) experiments. The evidence indicates that in standard CPR games without communication and without sanctioning possibilities inefficient excess appropriation is...

In an experiment we study market outcomes under alternative incentive structures for thirdparty enforcers. Our transactions resemble an anonymous credit market where lenders can give loans and borrowers can repay them. When borrowers default, judges are free to enforce repayment but are...

This paper provides evidence that free riders are heavily punished even if punishment is costly and does not provide any material benefits for the punisher. The more free riders negatively deviate from the group standard the more they are punished. As a consequence, the existence of an...

We use an experiment to explore how subjects learn to play against computers which are programmed to follow one of a number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious play, imitation, reinforcement learning, and a trial...

We experimentally investigate how reputational concerns affect behavior in repeated Tullock contests by comparing expenditures of participants interacting in fixed groups with the expenditures of participants interacting with randomly changing opponents. When participants receive full...

We experimentally investigate spillover effects of affirmative action policies on team performance and the willingness to work in teams. We find that such policies in form of gender quotas do not harm performance and cooperation within teams, and do not discourage selection into teams.

A growing experimental literature studies the endogenous choice of institutions to solve cooperation problems arising in prisoners' dilemmas, public goods games, and common pool resource games. Participants in these experiments have the opportunity to influence the rules of the game before they...
