摘要：We show that in symmetric two-player exact potential games, the simple decision rule imitate-if-bettercannot be beaten by any strategy in a repeated game by more than the maximal payo¤ di¤erence of the one-period game. Our results apply to many interesting games including examples like 2x2 games, Cournot duopoly, price competition, public goods games, common pool resource games, and mini- mum e¤ort coordination games.
