交换经济的一种市场过程

A Market Process of the Pure Exchange Economy

本文描述和分析了经济的一种市场交换过程，试图为一般均衡理论找到现实世界的交易基础，文章证明了以下结论：（1）在一定条件下，商品交换会形成稳定的均衡市场，而商品交换的一般结果是帕累托最优的交换结果：（2）个人主观的商品价值判断通过商品交换形成一个客观和统一的商品价值判断；（3）重复交易的预期会使一般交换结果成为一般均衡的交换结果，因此，商品价格是由经济主体自由的商品交换形成的，这为现实交换和一般均衡理论搭起了一座桥梁。

This paper develops a theoretical model that describes and analyzes the process of market exchange.It tries to fill the gap between the pattern of real-world transactions and the existing general equilibrium results.Several results emerge from the theory.First,market transactions form a stable equilibrium market under certain conditions and the final allocation is Pareto optimal.Second,Individuals'subjective valuation is translated into a common objective social valuation via market transactions. Third,the expectation of repeated transactions induces dispersed market transactions to form a general equilibrium.This last result gives general equilibrium prices a transaction- based foundation and thus closes the gap between real-world transactions and the general equilibrium results.
