关于宏观经济学微观基础的若干问题

An Analysis of the Problems Existing in the Micro-basis Study of Macroeconomics

传统宏观经济理论缺乏微观基础,而新古典(New Classical)革命和新凯恩斯(New Keynesian)革命都试图把宏观经济分析建立在稳固的微观基础上,认为宏观经济学应是经济主体在约束条件限制下,根据对宏观经济形势的预期进行最优化行为这一基础上去确定宏观经济总量,但是宏观经济学的微观基础研究的局限性也随之突显出来。因此,从物理经济学的角度,分别讨论宏观经济学的微观基础,旨在探讨研究中所涉及的"代表性个体"、"预期机制"、"计量验证"等分析模式中可能存在的问题。

Traditional macroeconomic theories lack a microeconomic basis, so theories of New Classical Economics and New Keynesian Economics have both tried to base their macroeconomics on the stable microeconomic basis, holding that macroeconomics is intended to help the subject of macro - economy make the rational choice by predicting the macroeeonomic situation, thus pursuing the optimal interest. Nevertheless, as the result of it, the limitations of the micro - basis study of macroeconomics are made apparent. Hence this paper attempts to expound the potential problems existing in the analytical pattern involved in the micro - basis study of macroeconomics such as ＂representative individual＂, ＂expectation mechanism＂, ＂econometric verification＂ from the perspective of econophysics.
