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...

Technical supplement to the paper forthcoming in Rand Journal of Economics.

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...

This paper studies the bilateral contracting environment where multiple principals negotiate contracts with multiple agents independently. It is shown that equilibrium allocations associated with (pure strategy) perfect Bayesian equilibria relative to any ad hoc set of negotiation schemes can be...

We investigate equilibria of sealed-bid second price auctions with bidder participation costs in the independent private values environment. We focus on equilibria in which bidders use cut-off strategies (bid the valuation if it is greater than a certain cut-off point, otherwise do not...

We investigate whether efficient collusive bidding mechanisms are affected by potential information leakage from bidders' decisions to participate in them within the independent private values setting. We apply the concept of ratifiability introduced by Cramton and Palfrey (1995) and show that...

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...

This paper studies asymmetric first-price menu auctions in the procurement environment where the buyer does not commit to a decision rule and asymmetric sellers have interdependent costs and statistically affiliated signals. Sellers compete in bidding a menu of contracts, where a contract...

If the agent's preference relation satisfies a strict monotonicity condition in common agency under the asymmetric information, the set of all equilibrium allocations in the menu game where menus of contracts are allowed coincides with the set of all equilibrium allocations in the single...
