This paper presents a model of delivered nonlinear pricing by duopolists operating in a linear city with two types of consumers and having incomplete information. At each location, the higher cost firm offers a uniform price equal to its delivered marginal cost while the lower cost firm offers a nonlinear tariff. For nearby locations, the lower cost firm may charge monopoly nonlinear prices, but as the distance increases the quantity consumed by the low valuation consumer becomes less inefficient than under monopoly. In the market region closest to the competitor's market we get an efficient outcome. If firms choose locations, before choosing tariff schedules, they will locate at the median of their equilibrium sales distribution.
