【摘要】We propose a notion of "robust rationalizability": an action is robustly rationalizable for a given type if it is rationalizable for any small perturbation of higher-order beliefs of that type. We give a full characterization of robust rationalizability, and apply it to economic environments such as auctions and the Cournot competition. We also revisit Weinstein and Yildiz (2007), which, under a so-called richness assumption, provides a critique for selection/refinements based on global games.Our result delineates the boundary of the Weinstein-Yildiz critique.
