| 摘 要： | 建立一个考虑到市场效率因素的非线性非瓦尔拉斯均衡蛛网模型,在确定与非确定两种情形下对其研究分析.模型的均衡特征分析表明,现实市场具有四种可能情形的均衡,一种传统的瓦尔拉斯意义下的均衡和三种非瓦尔拉斯均衡.无论在确定的还是在非确定的市场中,在一定条件和一定收敛意义下,市场价格都可以稳定到市场的均衡价格,从而把市场推向这四种可能的均衡之一. |
| 关 键 词： | 蛛网模型 非瓦尔拉斯均衡 均衡价格 均衡特征. |

| Abstract: | A nonlinear cobweb model of non-Walrasian equilibrium, inwhich the market efficiency is taken into consideration, is studied forboththe deterministic and stochastic cases. The analysis of the equilibriumcharacters shows that in the real market there are four kinds ofequilibria, of which one is traditionally Walrasian and the others arenon-Walrasian. Under the given conditions and in some sense ofconvergence, the market price can, in both the deterministic andstochastic cases, approach to the equilibrium price, hence drives themarket to one of the four equilibria. |
