偏好结构、策略远见和集体行动

Preference Structure,Strategic Foresight and Collective Action

个体参与集体行动的微观动因既有偏好性因素也有策略性成分。本文用框架依赖的效用函数同时表达自利偏好和不同类型社会偏好的作用,以个体行为理性为逻辑起点推导了个体依据框架调整的集体行动合作行为,其行为符合新古典需求理论。根据策略远见理论解释了集体行动中个体合作的策略动因。通过单次博弈的公共物品实验和问卷调查,分离了偏好结构与策略远见对集体行动的影响。实验结果表明存在一定的基于远见而合作的个体,个体同时也具有利他和不平等厌恶等偏好动因,个体的主要集体行动合作动因是偏好结构与策略远见的复合动因。这一结果说明个体在单期和长期内的合作都需要综合考虑自利理性和社会偏好等多重动因。

The individual motivation of participation in collective action includes preference and strategy considerations.This paper employs the framework-dependent utility function to analyze the influence of self-regarding preference and several kinds of social preference,and explains the individual framework-dependent cooperation behavior based on rationality assumptions.The individual behavior can be described by using neo-classical demand theory.The strategic foresight theory has been used to rationalize the individual cooperation.The impact of preference structure and rationality has been separated using a one-shot public good experiment and a questionnaire followed it.The result shows that,there exist some foresight-based cooperating subjects;people also have social preference motivation such as altruism and inequality averse.The main individual cooperation motivation are the synthetical reason of preference structure and strategic foresight.This result highlights the reason why subjects cooperate in collective action.It suggests that we should consider self-regarding rationalization and social preference motivation.
