本文研究了网络化Bertrand寡头垄断市场中位于网络顶点的厂商与相邻厂商进行价格竞争的行为演化。这种网络模型也适用于多维差异化产品的市场。在非网络化市场中,Bertrand-Nash均衡定价是进化稳定的。然而,我们发现,在我们的大型网络化市场中,Bertrand-Nash均衡价格是不稳定的,但合谋价格是弱选择下的进化稳定。随着运输成本的增加,从长远来看,企业收取的价格会更加合谋。结果表明,合谋定价盛行在一个大的市场,当且仅当它是网络。
This paper studies evolution of firms’ behavior in a networked Bertrand oligopoly market, in which firms who are located on vertices of a network compete in price with their neighbors. This network model is also applied to a market with multi-dimensionally differentiated products. In a non-networked market, it is known that the Bertrand–Nash equilibrium pricing is evolutionarily stable. We show, however, that in our large networked market, the Bertrand–Nash equilibrium price is not stable but a collusive price is evolutionarily stable under weak selection. As the magnitude of transportation cost increases, firms charge a more collusive price in the long run. The results suggest that collusive pricing prevails in a large market if and only if it is networked.
