超越经济人的社会偏好理论:一个基于实验经济学的综述

实验经济学对传统经济人假设的系统反驳促使社会偏好理论应运而生.社会偏好理论的各个模型试图在维持理性假设下,通过将基于心理学和社会学的诸如公平、互利等与“自利”假设有着明显涵义辨识度的一些人类社会性情感因素纳入到效用函数中来进而修正经济人假设,并以博弈论为基本的分析工具力图构建新的博弈均衡来解释实验经济学所揭示的一系列悖论.本文围绕社会偏好在已有文献的基础上对其产生的背景、模型、测度、外溢以及检验等问题作了一个详细而系统的梳理

Theories of Social Preferences Beyond Homo Economicus:A Review Based on the Experimental Economics

Theories of social preferences is developed when experimental economists have gathered overwhelming evidences that systematically refute the self-interest hypothesis.Maintaining the assumptions of rationality,economic models of social preferences try to take the elements of people’s social emotions such as fairness,reciprocity and so on into the utility functions to modify the assumptions of self-interest.In this way,theories of social preferences try to construct new game equilibriums in order to explain the paradox in experimental games using the game theory as the basic analysis tools.This paper made a detailed and systemic review based on the literatures about the context,models,measurment,external validity and test of theories of social preferences.
