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。 Von Neumann utility theory is the analysis of consumer behavior theory that occurs repeatedly in logic time under risky conditions. This theory holds the cardinality point of view, which defines utility through the choice of probability and is now widely used in theoretical analysis of monetary economics. The theoretical significance of von Neumann’s utility lies in that it has injected new vitality into the classical cardinal utility theory and its existing problem is that the objectivity of the utility index is widely questioned.
