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 principal’s rent extraction. This is due to the coalitional efficiency between(More)
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 implementable only with mechanisms which will be rejected on(More)
We consider an adverse selection environment, where an agent is able to understate his productivity, but not allowed to overstate it. We characterize the principal’s optimization problem. The solution to this problem is generally different than the solution to the standard problem, where no restriction is made on the statements that the agent can make. We(More)
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 cuto¤s, we provide an example where it is asymmetric. We then investigate when the(More)
We study an incomplete information game in which players can coordinate their actions by contracting among themselves. We model this relationship as a reciprocal contracting procedure where each player has the ability to make commitments contingent on the other players’commitments. We characterize the outcomes that can be supported as perfect Bayesian(More)
