We consider Bayesian incentive compatible and individually rational mechanisms for resolving conflicts between two agents who are uncertain about each other's fighting potential. We model the default option of outright conflict as a probabilistic contest. Examples of such contests may be...

A hierarchically structured rent-seeking contest may be associated with lower equilibrium expenditure than a corresponding flat contest. In this chapter we discuss how this fact may be used to explain the structure of organizations such as firms, including why firms commonly have outside owners.

This paper studies strategic delegation in two-player contests for an indivisible prize (as in, e.g. litigation) where one party's probability of winning is determined by the relative investments of both. Even though neither player stands to gain anything from the possibility of one player...

In a first-price all-pay auction buyers have an incentive to delegate the bidding to agents and to provide these agents with incentives to make bids that differ from the bids the buyers would like to make. Both buyers are better off in this strictly non-cooperative delegation equilibrium and the...

We consider a two-player contest for a prize of common but uncertain value. We show that less resources are spent in equilibrium if one party is privately informed about the value of the prize than if either both agents are informed or neither agent is informed. Furthermore, the uninformed agent...

We discuss attempts to justify conditional cooperation in the Prisoners’ Dilemma based on the idea of identifying an opponent’s strategy. We note that the concept of such complete transparency of decision procedures is logically inconsistent. Furthermore, we observe that attempts to justify...

We suggest an operational definition of transaction cost as the expected value of strategy information in games played by individuals randomly matched from a large population. We relate the concept of a transaction cost minimum to those of Nash equilibrium, efficiency, and evolutionary...

We study the long-run behavior of an economy where agents who are heterogeneous with respect to risk attitudes can either earn a certain income or enter a risky rent seeking contest. In contrast with standard evolutionary game theory, we distinguish between utility and material payoffs, and...
