Nonparametric tests for strategic interaction effects with rationalizability

Research output: Contribution to journalArticle


We introduce the first nonparametric tests for the presence and the sign of strategic interaction effects in discrete 2 × 2 games of complete information under the assumption of rationalizable behavior, which includes Nash Equilibrium as a special case but allows for incorrect beliefs. Our tests assume the existence of an observable covariate with a positive stochastic relationship with the payoffs of a particular player.
