A number of papers have shown that a strict Nash equilibrium action profile of a game may never be played if there is a small amount of incomplete information. The authors present a general approach to analyzing the robustness of equilibria to a small amount of incomplete information. A Nash...

If an agent's preferences over subjectively uncertain acts are consistent with him having a subjective probability distribution over the states of nature, then those preferences can induce consistent preferences over 'objectively' risky lotteries. Such 'probabilistically sophisticated' behavior...
