This paper studies the principal-multiagent model of a firm subject to adverse selection. We focus on agents who have complete information. We propose some desirable properties to be satisfied by mechanisms implementing the first-best in Nash equilibrium: (i) enforceability (a property related...

We consider the problem of allocating m(m=2) infinitely divisible commodities among agents with single-peaked preferences. In the two-agents case any strategy-proof and efficient solution is dictatorial. First, we propose a solution that, in the two-agents case, is the only one that satisfies...
