理性选择向非理性选择转化的行为分析

A Behavioral Analysis of the Transformation from Rational Choice to Irrational Choice

本文针对不确定条件下的人类选择行为提出一个新的可供研究的观点:人的非理性选择在很大程度上是由理性选择转化而来的。文章首先简要评说了早期行为经济学的动物实验和认知心理学,认为人的选择行为是理性和非理性的同构;继而,通过解析丹尼尔·卡尼曼等人创立的前景理论所蕴涵的理性向非理性选择转化的思想,构建了这种转化的抽象模型;最后,作为对本文分析观点的一种联系实际的论证,研究了金融市场中的非理性选择以说明这种转化现象的客观存在。本文的分析可视为对行为经济学非理性选择理论之深邃见解的一种挖掘。

Aiming at human choice behaviors under uncertainty, this paper puts forward a new and needing well researched viewpoint： human＇s irrational choices transform to a great extent from rational choices. First this thesis comments briefly animal experiments in early behavior economics and perceive psychics, and deems that human choice behaviors are the isomorphism of rationality and irrationality; Secondly, through parsing the transforming thought from rationality to irrationality in D. Kahneman＇s prospect theory, the author conceives an abstract transformation model; Lastly, as a practical demonstration, we study those irrational choices in financial markets to prove the objective exist of those transformation phenomena. This paper＇ s analysis can be counted a dig out of behavior economics＇ abstruse opinion about irrational choice theory.
