論文提要

This paper constructs a two-dimensional framework to take into consideration both horizontal and vertical differentiation. The focus of the paper is on the impact of vertical (quality) differentiation to firms’ location configuration. It employs a two-stage game, in which firms first simultaneously decide optimal locations and then play Bertrand price competition with three pricing policies. This paper shows that while the Principle of Minimum Differentiation may occur, the Principle of Maximum Differentiation can never emerge, if firms engage in spatially discriminatory pricing. It also shows that spatial agglomeration is the unique location equilibrium in both cases where firms charge uniform delivered and mill pricings. Moreover, this paper proves that the above results still hold even if the quality levels are endogenously determined.
