On the Equivalence of Bayesian and Dominant Strategy Implementation for Environments with Non-Linear Utilities

We extend the equivalence between Bayesian and dominant strategy implementation (Manelli and Vincent, Econometrica, 2010; Gershkov et al. Econometrica, 2013) to environments where agents have utilities that are non-linear in allocations and satisfy a convex-valued assumption. The new equivalence result produces novel implications to the literature on the principal-agent problem with allocative externalities, environmental mechanism design, and public good provision
