摘要
经济行为人的理性假设是现代经济学体系构建的逻辑基础。主流经济学以完全理性作为其前提假设,并得出行为人可以在诸多决策方案中进行最优选择的结论;但是,完全理性假设不仅在真实性方面存在缺陷,而且在逻辑推理上和实践检验中都遭到质疑。实际上,行为人的理性是有限的,在此前提下,新制度经济学、演化经济学和行为经济学等经济学分支构建了自己的学科体系并创建了行为人在有限理性条件下的真实选择模式。
The rationality hypothesis of economic agents is the logic foundation of modern economics. Homo-economics is based on agents＇ perfect rationality, and agents can attain the maximum object out of all the choices. However, the perfect rationality not only fails to be true, but fails in the logic reason and practical examination. Actually, agents have only bounded rationality on which new institutional economics, evolutionary economics and behavior economics, etc, establish respective system and construct the agents＇ real choice models.
