The strategic incentives, with respect to the choice of price policy in spatial competition, are analyzed in a duopoly model. Price discrimination emerges as the unique equilibriu m outcome in games with either simultaneous choice of policy and pric e or sequential choice where firms may commit first to uniform mill p ricing before the actual market stage. Nevertheless, profits may be h igher with uniform pricing. The authors' models are applied to analyz e some common business practices that arise in geographical pricing, like the basing point system, and in the pricing of varieties or opti ons from a base product in a product-differentiation context.
