社会再生产视角下的经济波动:一个马克思主义RBC模型

Economic Fluctuation from the Perspective of Social Reproduction:A Marxist RBC Model

本文在吸收借鉴马克思主义最优经济增长理论的基础上,构建了一个马克思主义RBC模型,并以此来探讨社会再生产视角下的经济周期特征。研究发现,两大部类的技术进步冲击对劳动配置与经济波动的影响截然不同。任何一个部类的技术进步都将引导劳动更多地配置于该部类之中,同时也将改变两大部类的产出量,并进一步引发社会再生产结构的变化。伴随着上述过程,两大部类单位产品所包含的价值也会发生变化,进而导致价值总量、资本有机构成与利润率相应变动。此外,本文还对反映剥削程度的劳资关系进行了分析,通过模拟发现劳资关系的变化将显著改变经济周期在波动性、协动性以及粘持性等方面的特征。

This paper constructs a Marxist RBC model,based on absorbing the Optimal Economic Growth Theory of Marxism,to explore the characteristics of the economic cycle from the perspective of social reproduction.The research presents that the impact of the Two Major Categories'technological progress on the allocation of labors and economic fluctuations is different.Whichever of the Two Major Categories achieve technical progress will lead much more labor allocation in the sector,and will change the output of the two categories,furthermore will cause changes in the structure of social reproduction.Accompanied by the process above,every commodity's value of the Two Major Categories will probably change,with a corresponding modification in the total value of capital,the organic composition of capital and profitability.In addition,this paper also analyzes the labor relations which reflect the degree of exploitation,our simulation presents that changes in labor relations will significantly change the economic cycle on the character of volatility,comovement and persistence.
