国内外已有的关于公平偏好的研究主要集中于获取人们普遍存在公平偏好心理的证据,尚缺乏对公平偏好固有性质的深入挖掘。本文借鉴Andreoni等的研究方法,设计了参照依赖实验,规范组织实施了多场次可控实验,探索了公平偏好的性质特征。实验结果显示人们的同情偏好呈现敏感性递减的变化规律且不存在拐点,而嫉妒偏好和自豪偏好均呈现先敏感性递减后经过拐点敏感性递增的变化规律;通过拟合公平偏好的函数表达式,分析其数学性质和经济学属性,发现嫉妒偏好的边际效用几乎是同情偏好的10倍,解决了将公平偏好因子引入传统的委托-代理模型的合理性问题,修正了传统的委托-代理模型。
The existing researches on fair preference both at home and abroad have focused on obtaining evidence that people have a fair psychological preference. However, there is still a lack of in-depth exploration of the intrinsic nature of fair preference. This article draws on Andreoni et al.’s research methods, designs the reference dependence experiment, standardizes the organization and implementation of the multi-field controllable experiment, explores the nature and characteristics of the fair preference. The experimental results show that people’s sympathy preferences show a decreasing trend of sensitivity and there is no inflection point, while the preferences of jealousy and pride preference show the changing rule of sensitivity increasing gradually after the sensitivity decreases. By fitting the function formula of fair preference , Analyzes its mathematical properties and economics attributes and finds that the marginal utility of jealous preference is almost 10 times the preference of sympathy and solves the problem of rationality of introducing fair preference factor into traditional principal-agent model, and modifies the traditional principal-agent model .
