Lexicographic Probabilities and Equilibrium Refinements
从决策理论出发，用非阿基米德主观期望效用理论刻画了正规形式的完美均衡和适当均衡，为博弈论学者提供了新的均衡精炼方法。
This paper develops a decision-theoretic approach to normal-form refinements of Nash equilibrium and provides characterizations of (normal-form) perfect equilibrium and proper equilibrium. The approach relies on a theory of single-person decision-making that is a non-Archimedean version of subjective expected utility theory. Copyright 1991 by The Econometric Society.
