Does mutual knowledge of preferences lead to more Nash equilibrium play? Experimental evidence

摘要

People frequently exhibit behavior that seems to be inconsistent with the standard Nash equilibrium prediction. Prominent examples are cooperation in one-shot social dilemma situations such as in prisoner's dilemma games or in public goods games. It does not seem plausible that a lack of rationality is the driving factor of this behavior because the underlying interactions are rather simple. 1 In many applications, Nash equilibria are determined by using the players' own material payoffs in the game. Typically,
