演講摘要 : I develop a game-theoretic solution concept in which agents have misperceptions about causality. In an observation-consistent equilibrium (OE), each player best responds to a belief about Nature or other players' actions consistent with observed outcomes. A maximum-entropy observation-consistent equilibrium (MOE) is an OE in which each player's belief maximizes the Shannon entropy among all observation-consistent beliefs. Every finite extensive-form game with perfect recall has a MOE. The equilibrium captures common causal misperceptions of correlation neglect, omitted-variable bias, and simultaneity bias. When players observe outcomes perfectly, OE and MOE are equivalent to self-confirming equilibrium and perfect Bayesian equilibrium.
