新古典宏观经济学的产生及其发展

Emergence and Development of New Classical Macroeconomics

从卢卡斯开始的理性预期革命对凯恩斯宏观经济进行了严厉批判，并在西方经济学界倡导了所谓寻找宏观经济学的微观基础的思想，８０年代以后，巴罗、普雷斯科特等为代表的新古典宏观经济学“第二代”学者以实际周期理论代替货币周期理论，并对财政政策和政府决策行为进行了新的探索。本文在介绍分析新古典宏观经济学的产生及发展的基础上认为，该学派研究促进了人们对宏观经济理论和政府决策行为的深入思考，但该学派保守的思想倾向以及过于关注计量经济学方法而忽视经济学的价值判断的研究方法却是根本错误的。

Abstract The Rational Prediction Revolution initiated by Robert Lucas severely criticized the Keynesian Macroeco-nomics, and innovated a movement of searching for the micro basis of macroeconomics among the Western economists. After the 80s, a second generation of the New Classical Macroeconomists represented by Robert Barro and Edward Prescott put forward a practical cycle theory to replace the currency cycle theory, and undertooknew explorations into the financial POlicies and policy-making of the government. Having attempted to analyzethe rise and development of the New Classical Macroeconomics, this article points out that studies of this schoolof economics has promoted profound considerations into the theories of macroeconomics and the POlicy--making ofthe government. However, it's conservative tendency and over-emphasis on the method of quantitative economicswhile neglecting value judgement of economics are its serious defects.
