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...

We develop and test a framework of mental information representation in an asset market setting. The model predicts heterogeneous trading behavior as a consequence of two distinct mental capabilities: analytical skills and mentalizing, where the former involves quantitative, objective aspects of...

We study the stability of voluntary cooperation in response to varying rates at which a group grows. Using a laboratory public-good game with voluntary contributions and economies of scale, we construct a situation in which expanding a group's size yields potential efficiency gains, but only if...

In this paper we show that subtle forms of deceit undermine the effectiveness of incentives. We design an experiment in which the principal has an interest in underreporting the true performance difference between the agents in a dynamic tournament. According to the standard approach, rational...
