多重均衡选择中的风险占优与混合策略

均衡选择理论是博弈理论的重要组成部分.风险占优均衡是人们经济决策或行为的一个主要结果.利用混合策略及其性质和“抵制”的概念,“支持”了海萨尼和泽尔腾用公理定义的风险占优概念,且具体给出了识别风险占优均衡的标准和方法,并把它们推广到对称博弈中去.最后对均衡占优的直觉概念和风险占优相冲突的一些博弈进行了类似的讨论.

Risk Dominance in Multi-equilibrium Selection and Mixed Strategy

The theory of equilibrium selection is an important part of game theory. An equilibrium of risk dominance is a main outcome of economic decision and behavior for man. In this paper, we will use mixed strategy and its properties, the concept of resistance, and support the risk dominance is defined by J.Harsanyi and R.Selten applying axiom, and give explicitly the criterion and method of distinguishing a risk dominance and generate they to symmetric games. Finally, we will discuss similarly to some games in which there is conflict among the intuitional concept of equilibrium dominance with risk dominance.
