实际经济周期理论(Real Business Cycle Theory,以下简称为RBC)是在20世纪70、80年代形成并发展起来的研究西方发达国家经济周期的理论。RBC理论的主要代表人物是卡耐基-梅隆大学的FinnKydland、明尼苏达大学的Edward Prescott、罗彻斯特大学的John Long等新古典宏观经济学家。其核心思想是较小的技术冲击可以产生较大的经济波动,经济周期是理性个人对实际冲击最优选择的结果,均衡结果是帕累托最优状态,政府干预并不能增进人们的福利水平。
The Real Business Cycle Theory (RBC) is a theory that was developed and developed in the 1970s and 1980s to study the economic cycle in the developed western countries. The main representatives of RBC theory are neo-classical macro-economists such as FinnKydland of Carnegie-Mellon University, Edward Prescott of the University of Minnesota, and John Long of the University of Rochester. The core idea is that smaller technical shocks can lead to greater economic volatility. Economic cycles are the result of rational individuals’ optimal choice of actual impact. The equilibrium result is Pareto optimality. Government intervention does not improve people’s welfare level .
