We study an incomplete information game in which players are involved in a reciprocal relationship that allows them to coordinate their actions by contracting among themselves. We model this as a competing mechanism game in which players have the ability to write contracts. We characterize the...

We study a mechanism design problem in which players can take part in a mechanism to coordinate their actions in a default game. By refusing to participate in the mechanism, a player can revert to playing the default game non-cooperatively. We show with an example that some allocation rules are...

We study the optimal auction problem with participation costs in the symmetric independent private values setting, where bidders know their valuations when they make independent participation decisions. After characterizing the optimal auction in terms of participation cutoffs, we provide an...

I study a multi-player mechanism design problem where the players are able to collude. I characterize the extent that the principal can link the compensation level of one of these players to the production performance of the other. I use this characterization result to identify the optimal...

We study an adverse selection problem, where an agent is able to understate his productivity, but not allowed to overstate it. The solution to this problem is generally different than the solution to the standard problem, where no restriction is made on the statements of the agent. We identify a...

We analyze an adverse selection environment with third party supervision. We assume that the "supervisor" and the "agent" can collude while interacting with the "principal". As long as the supervisor is symmetrically informed with the agent, the former's existence does not improve the...

In this paper, we develop a model of law enforcement with the possibility of corruption between enforcers and potential offenders. We study how the violation rate changes with the level of the fine imposed on violations. We find, in contrast to the conventional wisdom, that the fine level that...
