对等收费下网络之间的价格竞争

为促进竞争对手进入由在位者支配的网络产业,各国政府往往会制订一些管理定价规划,最常见的是对等收费,即对互联各方索取相同的接收费用,消除网内和网间的价格差别,使垄断可能性降低,据此,以电信市场为例,评估对等收费对网络间价格竞争的影响,在古诺模型和豪泰林模型的基础上,建立两个互联网络的价格竞争模型,在对称均衡下,网间电话的价格超过网内电话价格,这种内部电话折扣,即网络外部性促使市场倾斜,使产业走向垄断,通过对接收等价收取费用,即对等收费,消除了网内和网间价格差别,使垄断可能性降低。

Pricing Competition under the Principle of Reciprocity

It evaluates the effectiveness of the reciprocity pricing rule intended to promote entry into a network industry dominated by an incumbent carrier is studied.Drawing on the work of Cournot and Hotelling,a model of competiton between two interconnected networks are builded.In a symmetric equilibrium,the price of cross-network calls exceeds the price of internal calls.This tends to "tip" the industry to a monopoly equlibrium as a network externality.Byequalizing charges for terminating calls,reciprocity eliminates differences between internal and cross network prices and makes monopoly less likely.
