传统经济学在对垄断分析中,总是将垄断厂商的低供给水平,看作是衡量垄断的指标,即垄断厂商通过低供给来实现垄断.没有低供给这条假设,似乎就不能找到判定垄断是否存在的标准了.本文通过对垄断厂商与购买者的议价博弈进行分析,建立了一个产出可以由一系列议价结果所表示的模型.并指出如果将垄断厂商的议价信心指数(α)纳入到产量选择上,垄断厂商的决策将有很大改变.最后,本文得出,低供给只是解释垄断的部分原因.

A TU Game Analysis of Molopolists'Capacity Choice

This paper shows that undersuply determines monopoly only partially.And the monopolist's view of...
