We examine how leadership affects a dynamic public goods game. Using a setting where cooperation gains can be reinvested, our findings suggest that leadership has a positive impact on final wealth. Somewhat surprisingly, leadership also has a positive impact on reducing inequality within groups...

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...

The provision of public goods often relies on voluntary contributions and cooperation. While most of the experimental literature focuses on individual contributions, many real-world problems involve the formation of institutions among subgroups (coalitions) of players. International agreements...

Providing public goods is hard, because providers are best off free-riding. Is it even harder if one group's public good is a public bad for another group or, conversely, gives the latter a windfall profit? We experimentally study public goods provision embedded in a social context and find that...

We consider the interaction of intrinsic motivation and concerns for social approval in a laboratory experiment. We elicit a proxy for Fairtrade preferences before the experiment. In the experiment, we elicit willingness to pay for conventional and Fairtrade chocolate. Treatments vary whether...

We develop a model of social preferences for network games and study its predictions in a local public goods game with multiple equilibria. The key feature is that players' social preferences are heterogeneous. This gives room for disagreement between players about the "right" payoff ordering....

Public goods provision often involves groups of contributors repeatedly interacting with administrators who can extract rents from the pool of contributions. We suggest a novel identification approach that exploits the sequential ordering of decisions in a panel vector autoregressive model to...
