格雷欣法则与其逆法则转换机制探究--兼论完备理性及其实用性

摘要

本文试图提出完备理性假设，并将完备理性假设与完全理性假设和有限理性假设进行对比，通过引入理性度—制度效率模型，说明在完备理性假设条件下，制度作为外生变量对格雷欣法则与其逆法则转换之间的作用以及伴随转换而来的社会效率的帕累托改进。%This paper tries to put forward the complete rational hypothesis, and will compare the complete ratio-nal hypothesis, the completely rational assumption and the limited rationality hypothesis. By introducing the rational degree-system efficiency model,it shows that under the condition of a complete rationality postulate,the system as an exogenous variable has made a Pareto improvement on the social efficiency brought by the interaction between Gresh-am law and its law of inverse transformation and the conversion.
