We study the determinants of efficient behavior in stag hunt games (2x2 symmetric coordination games with Pareto ranked equilibria) using both data from eight previous experiments on stag hunt games and data from a new experiment which allows for a more systematic variation of parameters. In...

We use a two-phase experimental design to study how systematically manipulated beliefs about trust and trustworthiness can promote or deter cooperation. We use decisions in an initially played trust game to create five environments that differ in the information subjects have about the relative...

We investigate situations in which players make costly contributions as group members in a group conflict, and at the same time engage in contest with fellow group members to appropriate the possible reward. We introduce within group power asymmetry and complementarity in members' efforts, and...
