Comments on the Interpretation of Game Theory
讨论博弈论的解释问题，前半部分探讨“策略”概念，认为均衡策略描述玩家的行动计划及其最优性支持；后半部分主张好的博弈模型应真实反映决策者对现实社会现象的感知。
The paper is a discussion of the interpretation of game theory. The first half of the paper deals with the notion of "strategy". The paper endorses the view that equilibrium strategy describes a player's plan of action, as well as those considerations which support the optimality of his plan rather than being merely described as a "plan of action". In the second half of the paper it is argued that a good model in game theory has to be realistic in the sense that it provides a model for the perception of real life social phenomena. It should incorporate a description of the relevant factors involved, as perceived by the decision makers. Copyright 1991 by The Econometric Society.
