冯·诺依曼效用理论述评

The von Neumann's Expected Utility Hypothesis: A Review

冯.诺依曼效用理论是分析在有风险条件下存在于逻辑时间内事件重复出现的消费者行为理论。这一理论持基数观点,它通过选择的概率来定义效用,目前广泛应用于货币经济学理论分析中。冯.诺依曼效用的理论意义在于给古典的基数效用论注入了新的生机,其存在的问题是效用指数的客观性受到广泛质疑。

The utility hypothesis of von Neumann analyses consumers＇behavior in recurring events in a period of logic time under risk. Following the cardinal utility approach, it defines utility in terms of selected probability and has been widely used in theoretical analysis of monetary economics. Its theoretical significance lies in the fact that it injects new vitality into classical cardinal approach, but there is widespread doubt about the objectivity of its utility index.
