The Testable Implications of Zero-sum Games

Lee, Sangmok

Abstract

We study Nash-rationalizable joint choice behavior under restriction on zero- sum games. We show that interchangeability of choice behavior is the only additional condition which distinguishes zero-sum games from general non-cooperative games with respect to testable implications. This observation implies that in some sense interchangeability is not only a necessary but also a sufficient property which differentiates zero-sum games.
