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 consider an exchange economy in which agents possess private information at the time of engaging in state contingent contracts. While com-munication of private information is permitted, the true information state is not verifiable. The enforcement of contracts is, therefore, limited by...

An extensive experimental literature has documented miscoordination in establishing cooperative relationships when they can be supported in indefinitely repeated games: some people systematically try to cooperate, while others do not. The literature has had little success in finding personal...
