【摘要】This paper examines the socially optimal (and also equilibrium) locations of two stores or libraries on a linear market of unit length. If each consumer has probability $$w$$ of finding a desired product at each store; then the socially optimal locations are never completely centralized for full information; but are completely centralized for $$w \le 0.5$$ when costly visit search is necessary. The Nash equilibrium locations of two stores; and various alternative models for the socially optimal locations of two stores; are also examined.
