I consider a model in which an autocrat can be removed from power either through a military coup or a revolution by the citizens. In the event of a revolt by the citizens, the military may choose to support the autocrat to crush the revolt or play a passive role. The autocrat determines the...

This paper reviews the relatively small literature on sabotage in contests. It looks at both the formal game-theoretic literature and the empirical and experimental literatures. The treatment is intended to be intuitive with minimal use of technical jargon.

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...

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...

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...

There are two factions in a conflict. A third-party may choose to intervene by supporting one of the factions. We consider a third-party who maximizes a weighted sum of the welfare of the warring factions and the non-combatant population. In the case of a nonmilitary intervention, we obtain the...

Using the popular FOX TV reality show, American Idol, this paper makes a contribution to the literatures on the design of contests, the allocation of voting rights in committees, and the desirability of low-powered incentive schemes. In American Idol, the judges, who are presumably experts in...

People feel a sense of gratitude when they receive gifts, transfers, or assistance. Based on psychological literature, I argue that gratitude is different from standard notions of reciprocity. Indeed, people derive utility from in-kind transfers (i.e., feel grateful), even if they do not like or...

We examine equilibrium selection in a two-stage sequential elimination contest in which contestants compete for a single prize. This game has a continuum of equilibria, only one of which satisfies the Coalition-Proof Nash Equilibrium (CPNE) refinement. That equilibrium involves “burning out”...

In psychological games, higher-order beliefs, emotions, and motives - in addition to actions - affect players’ payoffs. Suppose you are tolerated as opposed to being genuinely accepted by your peers and “friends”. In particular, suppose you are invited to a party, movie, dinner, etc not...
