实际经济周期理论述评

Comments on Real Business Cycle Theory

由于卢卡斯批评的出现,宏观经济学在最近的20年里,又开始重新重视经济周期问题的研究。芬·基德兰德和爱德华·普雷斯科特开辟了这项问题的研究的一条新路,创立了所谓的“实际经济周期理论”。这一理论特别注意对经济微观主体应对经济环境变化的行为的观察。实际经济周期理论强调技术冲击是经济波劝的主要来源。在过去十多年里,实际经济周期理论的概念和方法已开始进入宏观经济学的主流。

With the Lucas Critique, macroeconomics has considerably refocused on the business cycle theory over the last twenty years. Finn Kydland and Edward Prcscott have led the way into what is now called Real Business Cycle Theory (RBC) with several studies featuring representative agents subject to technology innovations. And RBC holds that technology shocks are a major source of business fluctuations. In the last decade these concepts and methods have diffused into macroeconomics.
