经济学正在寻求新的微观基础吗
Is Economics Seeking a New Micro Basis
-
摘要: 西蒙和卡尼曼等人发展的行为经济学本质上采取了一种“经济学方法论弱个体主义”。这种新的理论范式坚持从个体出发，探讨社会经济问题；同时又通过认知双系统理论来引入社会因素，通过人的自利偏好与社会偏好的互动关系来刻画人的丰富性与多样性，这样就可以避开高度社会化的理论陷阱。但现在的行为与实验经济学的发展已经逐步偏离了西蒙、卡尼曼等人开创的研究路径，转而选择对新古典经济学的修补。行为与实验经济学有可能为经济学提供一个新的微观基础，但前提是回到西蒙与卡尼曼等人的思想路径。Abstract: The behavioral economics developed by Simon and Kahneman et al. essentially adopted a kind of “methodological weak individualism in economics”, the new theoretical paradigm insists on exploring social and economic issues from the perspective of individuals; at the same time, it introduces social factors through the cognitive dual system theory, and depicts the richness and diversity of human beings through the interaction between people’s self-interest preference and social preference, so as to avoid the theoretical trap of high socialization. However, the development of behavioral and experimental economics has gradually deviated from the research path initiated by Simon and Kahneman, and turned to mend the neoclassical economics. Behavioral and experimental economics may provide a new micro basis for economics, but the premise is to return to the ideological path of Simon and Kahneman.
