We provide a framework for analyzing collective action in contentious contexts such as protests or revolutions when individuals are uncertain about the relative payoffs of the status quo and revolution. We model the "calculus of protest" of individuals who must decide whether to submit to the...

In this study, we examine the effectiveness of the individual-punishment mechanism in larger groups, comparing groups of four to groups of 40 participants. We find that the individual punishment mechanism is remarkably robust when the MPCR is held constant despite the coordination problems...

We examine the effectiveness of the individual-punishment mechanism in larger groups, comparing groups of four to groups of 40 participants. We find that the individual punishment mechanism is remarkably robust when the marginal per capita return (MPCR), i.e. the return to each participant from...

We study informal insurance within communities, explicitly recognizing the possibility that subgroups of individuals may destabilize insurance arrangements among the larger group. We therefore consider self-enforcing risk-sharing agreements that are robust not only to single-person deviations...

Social and political inequality among individuals is a common driving force behind the breakdown in cooperation. In this paper, we theoretically and experimentally study cooperation among individuals faced with a sequence of collective-action problems in which the benefits to cooperation are...
