摘 要: 本文的目的是在现代经济学框架内分析非市场化利率偏低条件下一国经济的特征,并讨论进行利率市场化将对经济产生的影响。在经典拉姆齐模型的基础上,本文建立了一个劳动收入者和资本收入者相分离的双代表性个体的模型,劳动者作为储蓄者获得利息,而资本所有者作为投资者获得利润。这样,资本所有者和劳动所有者将面临不同的优化问题。我们发现利率非市场化的经济存在多条鞍点稳定路径。本文的分析着重考虑市场化之前经济的均衡和动态调整特征,以及市场化之后新的均衡和原均衡在资本存量与消费水平方面存在的差别,以刻画利率改革将对经济整体产生的影响。 The aim of this paper is to analyze what will happen when the interest rate begins to float freely from a regu- lated low level.The preliminary analysis of the paper shows that in the classical one-agent Ramsey model,the effect of interest rate is neutral.Going further from the classical Ramsey model,we build a two-agent model in which the labor-income and the capital-income are divided separately.In our model,labor earns wage and in- terest through saving;and capital earns profit as the owner of firm.The capital and labor will face different opti- mizing problem.Our discussion focus on the capital stock and consumption level change after the interest rate starts to float reflecting the supply and demand of the market
