subjective utility

In this paper, we analyze the limitations of traditional expected utility theory,study people s different attitudes towards risk under different gaining probabilities,construct security coefficient SC(p), and found subjective expected utility model on the base of SC(p).

分析了传统的期望效用理论在实践中的一些局限,研究了人们在不同获取概率下对风险的不同的态度,引入安全系数SC(p),建立了主观期望效用模型,并用此模型解释了一些期望效用理论模型所无法解释的矛盾。

Subjective expectation utility theory claims that personal probability distribution may derive from the behavioral preference,and a rational person s behavior choice should follow subjective expectation utility theory,however,the Ellsberg paradox demonstrates that no probability measure can be ascertained,and people s actual behavior choice is not always con- sistent with this theory.

主观期望效用理论认为个体的概率分布可以由行为的偏好导出,并且理性人的行为选择应该遵循主观期望效用理论,但是,埃尔斯伯格悖论显示了没有一个主观的概率测度,而且实际行为的选择并不总是和该理论的结果相一致。
