Players often engage in high-profile public communications to demonstrate their confidence in winning before they carry out actual competitive activities. We investigate players’ incentives to engage in such pre-contest communication. Our key assumption is that a player suffers a cost when he...

We consider a dynamic tournament where contestants choose a productive effort and to help or sabotage their opponents. Sabotage lowers the output of the victim. Moreover, sabotage imposes an additional direct psychic cost on the victim. Because the current leader is sabotaged most strongly in...

We model strategic mediation of the communication between an informed expert with a discrete type space and an uninformed decision maker. A strategic mediator can improve communication even when he is biased into the same direction as the expert.

This paper considers incentives for information acquisition ahead of conflicts. First, we characterize the (unique) equilibrium of the all-pay auction between two players with one-sided asymmetric information where one player has private information about his valuation. Then, we use our results...

This article presents a new theoretical perspective on the diversionary use of force. Players are partitioned into groups and choose how to allocate their resources to production, fighting against other groups, and fighting internally. The model gives a rationalist explanation of the group...

This paper completely characterizes the set of equilibria of the Vickrey auction for multiple identical units when buyers have non-increasing marginal valuations and there are at least three potential buyers. There are two types of equilibria: In the first class of equilibria there are positive...

In an interesting recent paper, Dari-Mattiacci and Parisi (2005) extended Tullock's (1980) rent-seeking game with an entry decision. The mixed strategies identified by Dari-Mattiacci and Parisi for the case of increasing returns in the contest success function (r2) do not constitute an...

This paper studies rent-seeking contests where the contestants do not know the number of actively competing contestants. Two models are compared. In the first, all players are risk neutral; in the second, all have constant absolute risk aversion. If the expected fraction of active contestants is...
