A MODEL OF SHOPPING CENTERS*
研究了开发商在购物中心租户组合和选址上的策略，发现消费者对产品多样性的偏好强弱决定了购物中心是聚集还是分散布局。
ABSTRACT In this paper, we propose a model of developers' strategies for tenant mixes and the locations of shopping centers (SCs). Consumers have preferences for product variety, and tenants in the SCs sell differentiated goods. The consumers can choose two shopping behaviors: patronizing one or both of the two SCs. We show that if the consumers have strong preferences for product variety, the SCs agglomerate to free‐ride on the rivals' product varieties, and the consumers patronize both SCs. On the other hand, if consumer preferences are weak, the SCs locate at different locations, and the consumers patronize one of the two SCs.
