Minimal Converse Consistent Extension of the Men Optimal Solution

Description

Minimal Converse Consistent Extension of the Men-Optimal Solution? I˙pek Ozkal-Sanver† November 8, 2009 Abstract In this paper we study two-sided, one-to-one matching problems and consider the most wellknown solution concept: the men-optimal solution. The men-optimal solution fails to satisfy consistency as well as converse consistency. Thanks to Sasaki and Toda (1992), we know that the minimal consistent extension of the men-optimal solution equals the core (Thomson, 1994a). In this paper, we compute the minimal converse consistent extension of the men-optimal solution as a correspondence which associates with each problem the set consist- ing of the men-optimal matching, and all stable and men-barterproof matchings for this problem.
