Abstract: We study a moral hazard problem with adverse selection in which a risk-neutral agent can directly control the output distribution and possesses private information about the production environment. The principal designs a menu of contracts, subject to limited liability, to induce effort. Departing from classical models, the principal can not only induce specific levels of effort but also regulate the supports of the implemented output distributions through contract design. We characterize the set of implementable output distributions in this environment. We provide sufficient conditions for the optimality of pooling and screening. In the latter case, it is necessary that the supports of the output distributions overlap only to a limited extent.
