How Do Switching Costs Affect Market Concentration and Prices in Network Industries?
通过动态双寡头价格竞争模型，研究了转换成本在网络产业中的作用，发现其影响取决于网络效应和外部选择的存在性。
I investigate the effects of switching costs on the market outcome in network industries using a dynamic duopoly model of price competition in the presence of an outside option. I find that the role of switching costs depends on network effects and the outside option. Without a viable outside option, high switching costs can neutralize the tendency towards high market concentration associated with network effects, but with a viable outside option, switching costs increase market concentration. Furthermore, switching costs lower prices if network effects are modest and there exists a viable outside option, but generally raise prices otherwise.
