A two-person infinite-horizon bargaining model where one of the players may have either of two discount factors, has a multiplicity of perfect Bayesian equilibria. Introducing the slightest possibility that either player may be one of a rich variety of stationary behavioral types singles out a...

We develop a general model, with the exponential bandit as a special case, in which high-ability agents are more likely to achieve early success but also learn faster that their project is not promising. These counteracting effects give rise to a signaling model in which the single-crossing...

Principal-agent problems can reduce gains from exchange available in long distance trade. One solution to mitigate this problem is multilateral punishment, whereby groups of principals jointly punish cheating agents by giving them bad reputations. But how does such punishment work when there is...
