【摘要】 不同带宽的网络接入服务商(ISP)需要有不同的定价策略.在消费者的单位时间成本不同情况下,分析了网络接入商的定价博弈.通过比较静态和动态的纳什均衡价格与收益,得到了接入服务商的先动优势,也得到了技术进步对宽带接入的有利性.然后分析了形成价格联盟后的最优定价,得出了不同带宽的接入服务商之间具有形成价格联盟的激励的结论,并使窄带接入退出市场.最后探讨了结成价格联盟以后社会总福利的变化情况,指出这种结盟对于社会整体来说是无益的.更多还原

【Abstract】 ISPs with different bandwidths should have different pricing strategies. This paper analyzes a pricing game between two ISPs with different bandwidths, considering consumers with different unit time costs. We get the ISP’s first_mover advantage through comparing static and dynamic Nash equilibrium prices and incomes. We also get the conclusion that the progress of technology will benefit ISP with broad bandwidth. Then, by analyzing optimal pricing of price alliance, we get the incentive of forming a price alliance and a conclusion that low bandwidth ISP will be cleared out from the market. Finally, comparison of social welfare before and after price alliance forming is presented to point out that this type of alliance may decrease total social welfare.更多还原
