实验检验累积前景理论

An experimental test on cumulative prospect theory

累积前景理论是前景理论的改进版本.前者使用CE范式对美国被试进行研究,得出如下几点结论:(1)人们的风险态度呈四分模式;(2)概率中大时,得时的风险回避比失时的风险寻求更明显;(3)价值函数的指数、权重函数的指数都小于1.采用相同的范式对中国被试进行考察,发现:(1)仍适用;(3)并不总是适用;(2)总是并不适用.

Cumulative Prospect Theory is a revised version of Prospect Theory. The former adopted CE research norm to study American subjects and got such conclusions： （i） People＇s risk attitudes have four-fold pattern; （ii） Risk aversion for gain is more pronounced than risk seeking for loss when the probabilities are moderate or high; （iii） The indexes of value function and weight function are less than I. This research adopted the same research norm to investigate Chinese subjects and found： （i） can be applied to Chinese subjects; （iii） cannot always be applied to Chinese subjects; （ii） can never applied to Chinese subjects.
