Reexamination of Maskin's Theorem on Nash implementability

  • Ziad, Abderrahmane

Abstract

We reexamine Maskin's Theorem by proposing slight modifications on Maskin's conditions of monotonicity and no veto power. We show that any social choice correspondence (SCC) that satisfies strict monotonicity, strict no veto power and unanimity can be implemented in Nash equilibria.
