消费者连续统集合下一种投入产出经济的均衡和一般均衡价格

Input-output Economy Equilibrium and General Equilibrium Price with a Continuum of Consumers

本文给出了一个经济模型把跨期间的一般均衡理论和neo Ricardian的生产价格理论联系起来 ,并改进了Rose AnneDana模型[1] [2 ] ,即把消费者有限改变消费者连续统 ,并在Rose AnneDana模型的基础上 ,加了条件C .4和C .7,得出了两个重要的结果 :(1)在标准条件下 ,此模型有一均衡使得每一个生产者的每期最大利润是相等的 ;(2 )如考虑生产价格是稳定价格 ,且等于最大利润 ,则在适当的条件下 ,这样的价格系统是存在且是唯一的 ,而所定义的均衡的非折扣的价格序列收敛于生产价格。因此均衡价格依赖于技术和消费者特征 ,但在取极限时 ,有关价格仅依赖于技术。

This paper gives an economics model which relates intertemporal general equilibrium theory with neo Ricardian production price theory and develops the model of Rose Anne Dana, which modifies finite consumers to consumers continuum. It adds two assumptions on the basis of the model of Rose Anne Dana, obtaining two main results:(1) under standard assumptions, this intertemporal model has an equilibrium such that in each period the rate of maximum profit is uniform among producers,(2)if it considers prices of production are stationary,which is equal to the rate of maximun profits,under mild conditions such a price system exists and is unique, and the sequence of undercounted prices of the equilibrium defined above converge to production price. Therefore, the equilibrium price relies on technology feature, but the price involved relies on technology when resolving limit.
