We study mechanism design problems in quasi-linear environments where the envelope theorem and revenue equivalence principle fail due to non-convex and non-differentiable valuations. We obtain a characterization of incentive compatibility based on the Mirrlees representation of the indirect...

We study a class of population games called stable games. These games are characterized by self-defeating externalities: when agents revise their strategies, the improvements in the payoffs of strategies to which revising agents are switching are always exceeded by the improvements in the...

We offer a parsimonious definition of large population potential games, provide some alternate characterizations, and demonstrate the advantages of the new definition over the existing definition, but also show the equivalence of the two definitions.
