This paper studies investment incentives in the steady state of a dynamic bilateral matching market. Because of search frictions, both parties in a match are partially locked–in when they bargain over the joint surplus from their sunk investments. The associated holdup problem depends on...

We study contracting between a consumer and an expert. The expert can invest in diagnosis to obtain a noisy signal about whether a low–cost service is sufficient or whether a high–cost treatment is required to solve the consumer’s problem. This involves moral hazard because...

We study an elimination tournament with heterogenous contestants whose ability is common-knowledge. Each pair-wise match is modeled as an all-pay auction where the winner gets the right to compete at the next round. Equilibrium efforts are in mixed strategies, yielding rather complex play...

We study the effects of allocative and informational externalities in (multi-object) auctions and related mechanisms. Such externalities naturally arise in models that embed auctions in larger economic contexts. In particular, they appear when there is downstream interaction among bidders after...

We consider social contracts for resolving conflicts between two agents who are uncertain about each other's fighting potential. Applications include international conflict, litigation, and elections. Even though only a peaceful agreement avoids a loss of resources, if this loss is small enough,...

We study the optimal design of organizations under the assumption that agents in a contest care about their relative position. A judicious definition of status categories can be used by a principal in order to influence the agents’ performance. We first consider a pure status case where...

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004This paper provides an analytical framework for studying principal-agent problems with adverse selection and limited commitment. By allowing the principal to use noisy communication we solve two fundamental problems of...

This paper analyzes bilateral contracting in an environment with contractual incompleteness and asymmetric information. One party (the seller) makes an unverifiable quality choice and the other party (the buyer) has private information about its valuation. A simple exit option contract, which...

This paper views authority as the right to undertake decisions that impose externalities on other members of the organization. When only decision rights can be contractually assigned to one of the organization’s stakeholders, the optimal assignment minimizes the resulting inefficiencies...

We study two-sided markets with a finite numbers of agents on each side, and with two-sided incomplete information. Agents are matched assortatively on the basis of costly signals. A main goal is to identify conditions under which the potential increase in expected output due to assortative...
