ON THE VALUE OF A LARGE CUSTOMER BASE IN MARKETS WITH SWITCHING COSTS*
在标准假设下（同质商品、均匀分布转换成本）证明，庞大客户基础可能因加剧价格竞争而损害企业利益，且转换成本降低市场竞争的效应比以往研究更强。
It is usually acknowledged that firms benefit from a large customer base in markets with switching costs. However, Klemperer [1995] argues that this may not be true if an increase in the size of a firm's customer base induces fierce price competition, making the firm worse off. This paper shows that such an outcome can be obtained under standard assumptions, such as homogeneous goods and uniformly distributed switching costs. In the model, firms have very limited incentives to fight for market shares, and the notion that switching costs make markets less competitive is stronger than previously shown.
