本文首先研究了今年诺贝尔经济学奖获得者基德兰德和普雷斯科特在宏观经济领域的主要学术贡献。他们共同创造了真实经济周期模型,重新解释了引起经济波动的原因以及相应的动力传播机制,为宏观经济学的发展指明了一个新的方向,同时对各国宏观经济政策的制定影响深远。最后,本文讨论了学术界对这一理论的批评。 This paper first studies the major academic contributions made by Kidd Randall and Prescott to this year’s macroeconomics in this year’s Nobel prize laureate in economics. Together, they created a real economic cycle model, reinterpreted the causes of economic fluctuations and the corresponding mechanisms of motivation, pointed out a new direction for the development of macroeconomics and profoundly influenced the formulation of macroeconomic policies in various countries. Finally, this article discusses the critics of this theory in academia.
