Template-Type: ReDIF-Paper 1.0 Title: Strategies Under Strategic Uncertainty Author-Name: Helene Mass Author-Email: hmass@uni-bonn.de Classification-JEL: D81, D82, D83 Keywords: Incomplete Information, Informational Robustness, Rationalizability Abstract: I investigate the decision problem of a player in a game of incomplete information who faces uncertainty about the other players’ strategies. I propose a new decision criterion — the rational maximin criterion — which works in two steps. First, I assume common knowledge of rationality and eliminate all strategies which are not rationalizable. Second, I apply the maximin criterion. Using this decision criterion, one can derive predictions about outcomes and recommendations for players facing strategic uncertainty. I analyze applications to first-price auctions, contests, and bilateral trade.
