Competition by Choice: The Effect of Consumer Search on Firm Location Decisions
研究企业选址与消费者搜索的关系，发现企业可能选择聚集在一起以吸引消费者比价，尽管这会加剧本地竞争，且在合理条件下这是唯一均衡结果。
This paper relates firm location choice and consumer search. Firms that cluster together attract consumers by facilitating price comparison, but clustering increases the intensity of local competition. The author constructs a simple model which shows that firms may choose head-on competition by locating together. Under reasonable conditions, this is the only equilibrium outcome.
