We show that, in environments with independent private values and transferable utility, a privately informed principal can solve her mechanism selection problem by implementing an allocation that is ex-ante optimal for her. No type of the principal can gain from proposing an alternative...

We investigate the issue of implementation via individually rational ex-post budget-balanced Bayesian mechanisms. We demonstrate that all social choice rules that generate a nonnegative ex-ante surplus, including ex-post efficient ones, can generically be implemented via such mechanisms. The...

In this paper we analyze a simple two-sided adverse selection model with one principal and one agent. They are both risk neutral and have private information about their type. We also assume that the private information of the principal is correlated with the one of the agent. The main result of...
