社会偏好下的互惠行为博弈扩展模型分析

Analysis of the Extended Game Model of Reciprocity Behavior Based on Social Preference

在博弈理论框架下,运用心理学和行为经济学理论方法建立互惠行为偏好函数,探讨互惠利他行为相互作用规律。在所提出的互惠行为偏好中,参与人的互惠行为偏好不仅依赖于自己行为所表示的善意或恶意,还依赖于其他参与人行为所表示的善意或恶意。该模型描述的心理和推理过程克服了已有社会偏好函数中存在的一些问题,并用于经典博弈的分析。

This paper applies the theory and methodology of behavior economics and psychology under the framework of game theory to construct a social preference function for researching the interactional law of reciprocity behaviors.A player＇s reciprocity preference not only depends on his hostile or friendly behavior,but also relies on another player＇ hostile or friendly behavior.The model resolves some problems that exist in other social preference theories,which can be applied to make classical game analyses.
