There is a collection of exogenously given socially feasible sets, and, for each one of them, each individual in a group chooses from an individually feasible set. The fact that the product of the individually feasible sets is larger than the socially feasible set notwithstanding, there arises...

In this paper, we develop a revealed preference methodology that allows us to explore whether time inconsistencies in household choice are the product of individual preference nonstationarities or the result of individual heterogeneity and renegotiation within the collective unit. An empirical...

Trust is fragile. It is hard to build but easy to destroy. In this paper, we explore the fragility of trust in a stylized laboratory environment. We ask whether transgression outside a direct send-and-return relationship destroys trust and, if so, whether a competition against outsiders or an...

We propose a simple non-cooperative game model in which two fragmented teams compete to increase their performance. The theoretical framework is based on the theory of conflict. We show that, depending on the value of a parameter in the model, the power of the competing teams may be expressed as...

We conduct a laboratory experiment to examine the performance of a market for protection. As the central feature of our treatment comparisons, we vary the access that “peasants” have to violence-empowered “elites”. The focus of the experiment is to observe how elites enforce and operate...
