Laws and policies designed to harness self-regarding preferences to public ends may fail when they compromise the beneficial effects of pro-social preferences. Experimental evidence indicates that incentives that appeal to self interest may reduce the salience of intrinsic motivation,...

This paper reports an experiment involving two mechanisms that allocate a single unit of an indivisible private good among two players, at no cost to either of them. Both mechanisms, proposed by Moore (1992) and Perry and Reny (1999), are compared in terms of their relative performance to assign...

This paper studies Nash implementation when the outcomes of the mechanism can be renegotiated among the agents but the planner does not know the renegotiation function that they will use. We characterize the social objectives that can be implemented in Nash equilibrium when the same mechanism...

This paper studies a 2-agent, 2-type principal-multiagent model of adverse selection under the assumption that the agents each have complete information. We construct a mechanism implementing the first-best contracts in Nash equilibrium that: satisfies a condition related to individual...

We study the dynamic implementation of the first-best forKing Solomon's Dilemma, on the assumption that boundedly rational players find their way to equilibrium using monotonic evolutionary dynamics. We find that all the mechanisms proposed by the literature fail to implement the first best...
