We study the stability of voluntary cooperation in response to varying group growth rates. Using a laboratory public-good game, we construct a situation where increasing group size yields potential efficiency gains, but only with sustained cooperation. We then study the effect of exogenously...

Twenty-four laboratory sessions were conducted to evaluate the roles of communication and group heterogeneity when … the public good. Without communication, members of heterogeneous groups tend to coordinate more on equal contribution … communication and heterogeneity, leading to less equitable distributions of payoffs as heterogeneity becomes more complex. A model …

Cheap talk communication thus completely solves miscoordination within groups and makes … group members act as a single agent. Furthermore, it is the larger group that benefits from communication at the expense of …

We test a mechanism whereby groups are formed voluntarily, through the use of voting. These groups play a public-goods game, where efficiency increases with group size (up to a limit, in one treatment). It is feasible to exclude group members, to exit one's group, or to form larger groups...

Understanding the motivations behind people’s voluntary contributions to public goods is crucial for the broader issues of economic and social development. By using the experimental design of Fischbacher, Gächter, and Fehr (2001), we investigate the distribution of contribution types in two...

This paper compares two methods to encourage socially optimal provision of a public good. We compare the efficacy of vigilante justice, as represented by peer-to-peer punishment, to delegated policing, as represented by the “hired gun” mechanism, to deter free riding and improve group...

We investigate the impact of various audit schemes on the provision of public goods, when contributing less than the average of the other group members is centrally sanctioned and the probability of an audit is unknown. We study how individuals update their beliefs about the probability of being...
