NON-WALRASIAN EQUILIBRIUM ANAlYSIS OF A COBWEB MODEL AND ITS RANDOM MODEL
一个非瓦尔拉斯均衡蛛网模型及其随机模型的研究

A nonlinear cobweb model of non-Walrasian equilibrium, in which the marketefficiency is taken into consideration, is studied for both the deterministic and stochastic cases.The analysis of the equilibrium characters shows that in the real market there are four kindsof equilibria, of which one is traditionally Walrasian and the others are non-Walrasian. Underthe given conditions and in some sense of convergence, the market price can, in both thedeterministic and stochastic cases, approach to the equilibrium price, hence drives the marketto one of the four equilibria.
