摘要
前景理论对基于个体理性的期望效用最大化决策原则提出了批判,该理论认为,不确定性条件下的个体决策存在框架效应、参考点和确定性效应等非理性行为。对120名大学生实验参加者进行了实验室实验,实验结果表明,不确定性条件下的个体决策存在风险态度的差异,这种差异表明个体的决策过程并不单纯是由期望效用所驱使,还受多种心理因素的影响,实验结果验证了个体决策过程中框架效应、参考点和确定性效应等非理性心理特征的存在。
Prospect theory has challenged the decision-making principle of expected utility maximization which based on rationality. According to the prospect theory, there are some irrational such as frame effect, reference point and cer-tainty effect in individual decision making under uncertainty. 120 undergraduates are made the subjects of the laboratory experiment, the experiment showing that the attitudes to risk are different under uncertainty. The difference indicates the decision making of individual is not only prompted by expected utility, but also influenced by some psychological factors. There are some irrational psychological characteristics, such as the frame effect, reference point and certainty effect.
