We present experimental results on a repeated coordination game with Pareto-ranked equilibria in which a payoff from choosing an action is positive only if a critical mass of players choose that action. We design a baseline version of the game in which payoffs remain constant for values above...

In finitely repeated prisoner dilemma games, two-person teams start out with significantly less cooperation than individuals, consistent with results reported in the social psychology literature. However, safety concerns quickly give way to teams cooperating significantly more than individuals....

We compare a partners condition where the same small group of subjects plays arepeated public good game to astrangers condition where subjects play this game in changing group formations.Subjects in the partners conditioncontribute from the first period on significantly more to the public good...

Experimental social scientists working at research-intensive institutions deal inevitably with subjects who have most likely participated in previous experiments. It is an important methodological question to know whether participants that have acquired a high level of lab-sophistication show...

This paper examines experimentally the reputation building role of disclosure in an investment / trust game. It provides experimental evidence in support of sequential equilibrium behavior in a finitely repeated investment / trust game where information asymmetry raises the possibility of...
