科斯命题的博弈特征与法律实效主义

Game Interpretation of Coase's Proposition and Legal Pragmaticism

科斯的方法特别强调相互性,从而导致我们从总体的角度看待法律问题。交易成本是法律经济学的关键词,交易成本主要来自于策略行为,所以现实中的科斯命题放在法律博弈论框架下会得到比较好的理解。纳什均衡的自我强制性为法律实施的有效性提供了基础,由此我们初步提出了法律实效主义大纲。

Coase's method focuses on reciprocity different from Pigou tax, so an overall perspective should be taken when allocation of right is taken into account. Transaction cost, mainly caused by strategy, is the core of Law and Economics; therefore, Coase's proposition can be better understood through Game Theory. Legal efficacy is based on enforcement by themselves in Nash equilibrium; thus an outline of Legal Pragmaticisim is worked out.
