Implementation of Bargaining Sets via Simple Mechanisms

We propose two simple mechanisms that implement two bargaining sets in super-additive environments. The first bargaining set is a close variation of the one proposed by L. Zhou (1994, Games Econom. Behav.6, 512-526), and the second is the Pareto optimum payoffs of the A. Mas-Colell (1989, J. Math. Econom.18, 129-139) bargaining set. We adopt a simple framework in which the cooperative outcomes are realized as non-cooperative subgame perfect equilibria in pure strategies of a two-stage game played by an auxiliary set of individuals competing over the cooperative agents.
