含有货币变量的宏观经济模型简析

Analysis on the Macroeconomic Model Including Money

现代宏观经济分析中,一般均衡框架是必不可少的重要因素。但是传统的一般均衡模型通常缺乏实际经济运行过程中一种不可或缺的因素———货币。所以,在传统的均衡或者非均衡模型中引入货币变量,并且判断和分析货币变量及货币政策的作用机制,就成为了货币经济学面对的一个挑战。通过对Tobin货币模型、货币内在效用模型和现金在先模型的分析表明,货币在经济中应该起到的确切作用和所承担的功能,尚未完全被清楚地认识,这为货币政策传导机制和作用机制过程中存在的不确定性留有大量理论探索的余地。

In the macroeconomic analysis, general equilibrium framework is a indispensable factor. However, traditionally general equilibrium models lack a essential factol through the real economic process - money. Therefore, it is a challenge faced by monetary economics that money variable is included in traditionally equilibrium or unequilibrium model and judge and analyze the effect mechanism of money variable and monetary policy. Through Tobin money model, money -in -the -utility function model and cash -in -advance model, this article analyzes that it is not fully understood the exact effect and functions of money, which provides the theory research for uncertainty in the transmission mechanism and effect mechanism of monetary policy.
