The Use and Abuse of Game Theory in International Relations

The author argues that the theory of moves, which has gained popularity in recent years as an alternative to game-theoretic analysis of strategic interaction, is fundamentally flawed. The theory's adherents argue that it makes theoretical progress by endogenizing the structure of games and introducing new ways of analyzing repeated interactions. The author analyzes the theory of moves from a game-theoretic perspective and challenges its theoretical claims. The author then reanalyzes several recent articles that have used the theory of moves, showing that its application to empirical cases is strained and that game theory can provide models that do a better job of fitting the stories the authors tell about them.
