Abstract

We present a general model of mixed oligopoly, where competing firms exercise spatial price discrimination. Our findings indicate that the Nash equilibrium locations of firms are always socially optimal irrespective of the number of competitors, the level of privatization, the form of the transportation costs and the number and/or the varieties of the produced goods. An immediate implication of this result is that this form of competition is preferable from a welfare point of view.
