科斯定理的数学阐述及思考

Mathematical proof and rethinking on Coase Theorem

有关论述科斯定理的文献大都将注意力集中于讨论定理揭示的经济意义,而忽略了定理本身的推导和证明。文章从"农夫与养牛者"的案例出发,给出科斯定理的数学推导,并试图分析不同产权界定对收入分配的影响及市场谈判对经济产出的影响。结果表明,不同的产权界定和谈判双方力量对比虽然不改变经济产出,却改变了经济个体的收入和财富分配。

Most literature on Coase Theorem focuses on the economical implications derived from this significant theory, however,the mathematical proof of the theorem has been disregarded. In this paper,on the basis of the case of 'the farmer and the rancher' mentioned by Ronald Coase,Coase Theorem is verified in a way of mathemetics,and the effects of different definitions of the property right on income allocation and the effects of commercial negotiations on outputs are analyzed.
