Recent bargaining experiments demonstrated an impact of anonymity and incomplete information on subjects' behavior. This has rekindled the question whether “fair” behavior is inspired by regard for others or is explained by external forces. To test for the importance of external pressure we...

We contrast a standard deterministic signaling game with one where the signal-generating mechanism is stochastic. With stochastic signals a unique equilibrium emerges that involves separation and has intuitive comparative-static properties as the degree of signaling depends on the prior type...

This paper provides a comparative statics analysis of punishment in public-good experiments. We vary systematically the effectiveness of punishment, that is, the factor by which punishment reduces the punished player’s income, and we find that contributions to the public good increase...
