正统经济学微观理论基础的解构

The Deconstruction of the Foundation of Orthodox Microeconomics

正统经济学的微观理论范式隐含了三个基础性假设:偏好的内涵不变性、偏好的外延无关性和经济资源的完全可替代性。行为经济学研究揭示了选择行为的结构化效应、引出效应、占有效应。这些研究表明,偏好关系在决策者与其身处的环境之间高度随机的互动过程中被塑造,并动态演进,偏好的内涵不变性和外延无关性假设受到了致命的质疑。思维会计原理作为多元的结构化过程,取消了经济资源的完全可替代性。正统经济学微观理论基础遭到了行为经济学的系统解构,经济学的关系论转向基本形成。

There are three assumptions hidden in the orthodox microeconomics ： the connotation invariance, extension independence, perfect substitutability of preference. Behavioral economists have systematicly illustrated framing effect, elicitation effect, and endowment effect. These important results demonstrate that preference relations are constructed by stochastic interaction between the decision - maker and the environment, and con- tinually evolve, which abrogates the assumptions of connotation invariance and extension independence. And the mental accounting discovered by behavioral economists abrogate the assumption of perfect substitutability of economic resources. All these results have deconstructed the foundation of orthodox microeconomics. Relationalism turn of economics came up.
