Multiproduct Search and the Joint Search Effect
构建了一个消费者从多产品企业顺序搜索多个产品的模型，发现多产品搜索会显著影响企业定价，甚至使市场价格随搜索成本下降，并讨论了模型的应用。
This paper presents a sequential search model where consumers look for several products from multiproduct firms. Multiproduct search can significantly influence firms' pricing decisions. For example, it can make market prices decrease with search costs. Possible applications of the model are also discussed.
