内容提要本文通过应用神经元经济学中的双系统理论,建模分析了经济决策者的理性程度与其财富水平间的关系。通过引入有限自我控制、鸵鸟效应等行为经济学概念,并通过剖析脑内不同脑区的互动过程,提出双系统模型并用以预测了两项经验事实:(1)决策者的理性程度随财富水平变化而变化;(2)在商品市场和金融市场中,这一变化方向是相反的,即在商品市场上,相对贫穷个体的消费行为更理性,而在金融市场上,相对富裕的个体行为更理性。本文在此基础上提出,效率与公平并非简单的此消彼长关系,当非理性经济行为广泛存在时,社会公平将有益于经济效率。 
AbstractThis paper models and analyses the relationship between a decision maker’s degree of rationality and his wealth level. By introducing some behavioral economic concepts, such as limited self-control and ostrich effect, and describing formally the interaction among neuro-systems, this paper developed a model, predicting to empirical facts: First, the degree of rationality varies with wealth level. Second, how the degree of rationality changes with wealth varies in commodity market and financial market; that is, the poor are more rational in budgeting, while the rich are more rational in investing. Based on these predictions, this paper argues that there seems to be a more complicated relationship between efficiency and equity. A more unprejudiced economy makes is, in some sense, more efficient, when irrationality is present.
