Social Norms and Economic Theory
对比了经济学中的理性人假设与社会学中的社会人假设,探讨了经济学家将规范导向行为还原为优化行为的尝试,并提出了关于社会规范与自利、共同利益及遗传适应度之间关系的若干问题。
One of the most persistent cleavages in the social sciences is the opposition between two lines of thought conveniently associated with Adam Smith and Emile Durkheim, between homo economicus and homo sociologicus. Of these, the former is supposed to be guided by instrumental rationality, while the behavior of the latter is dictated by social norms. In this paper I characterize this contrast more fully, and discuss attempts by economists to reduce normoriented action to some type of optimizing behavior. Social norms, as I understand them here, are emotional and behavioral propensities of individuals. Are norms rationalizations of self-interest? Are norms followed out of self-interest? Do norms exist to promote self-interest? Do norms exist to promote common interests? Do norms exist to promote genetic fitness?
