“科斯定理”并不是一个演绎的结论

Coase theorem isn't a deductive conclusion at all

一位经济学诺贝尔奖获得者乔治.斯蒂格勒(GeorgeStigler)宣称:"科斯定理"是一个演绎的结论.另一方面,在众多的经济学文献中都以一个双头模型来解释或证明所谓的"科斯定理".对于这个模型中所给的证明,众多引用此证明的文献都没有直接提出异议.笔者将在详细分析该模型的基础上指出,该模型中的证明是一个虚假的证明,这个所谓的证明从推导到结论的给出存在着隐蔽的诡辩.事实上,"科斯定理"根本不可能是一个"演绎"的结论.

A Economic Nobel Prize gainer allege that Coase theorem is a deductive conclusion. On the other hand, multitudinous literatures explain or prove so-called Coase theorem with duopoly model. But for the proof in this model, these literatures doesn＇t demur for it. This text points out on the basic of analyzing the model that the proof in this model is false one in which there exists covert sophism from deduction to conclusion. In fact, the Coase theorem isn＇t a deductive conclusion at all.
