In the very popular FOX TV reality show, American Idol, the judges, who are presumably experts in evaluating singing effort, have no voting power when the field is narrowed to the top twenty-four contestants. It is only the votes of viewers that count. In the 2007 season of the show, Simon...

Consider a world with two people, 1 and 2, where person 1 (the proposer) may offer to help person 2 (the responder). The proposer may be altruistic towards the responder either out of a genuine desire to make her happy or out of guilt. The responder derives disutility from apparent acts of...

Richer and more educated citizens demand better governance than poorer citizens. They participate more in the political process, are more difficult to buy off, and tend to have the financial resources to support a revolt. An autocrat who is politically insecure may therefore not invest in...

We consider a differential game of a conflict between two factions who both have a desire to exact revenge. We show that, in contrast to conventional wisdom, the desire for revenge need not lead to escalation of conflicts. Surprisingly, in the open-loop equilibrium, the weaker faction exerts a...

I present a two-player nested contest which is a convex combination of two widely studied contests: the Tullock (lottery) contest and the all-pay auction. A Nash equilibrium exists for all parameters of the nested contest. If and only if the contest is sufficiently asymmetric, then there is an...

A primary means of bureaucratic oversight is consumer complaints. Yet, this important control mechanism has received very little attention in the literature on corruption. I study a model of corruption with incomplete information in which consumers require a government service from officials who...
