构建宏观经济学的微观基础——论新凯恩斯主义学派对凯恩斯经济学的完善和发展

Constructing the Micro-foundation for Macro-economics: On the Contribution of Neo-Keynesianism to Keynesian Economics

传统凯恩斯经济学的一个致命软肋是缺乏微观基础,忽视供给分析,违背了经济人追求利益最大化的假设。"卢卡斯批评"抓住这一缺陷,构成了对传统凯恩斯主义经济学的理论挑战。新凯恩斯主义经济学家通过分析微观经济主体在产品、劳动、资本三大市场上的理性选择和追求最大化行为,深刻论证了导致宏观经济失衡的供给因素,揭示了微观主体行为同宏观经济失衡的内在联系,为凯恩斯宏观经济学构建了坚实的微观基础。

One definite weakness of the Keynesian orthodoxy is its lack of a micro-foundation and goes against the hypothesis of the pursuit of the optimal interest of economic man. 'Lucas Critique' poses a theoretic challenge to the Keynesian orthodoxy. The economists of Neo-Keynesianism have analyzed the rational choice and the pursuit of the optimal interest at the product, labor and capital markets by the subject of micro-economy and expounds the factors resulting in the un-equilibrium of micro-economy and its endogenous relation with the behavior of the micro-economics of Keynesianism.
