Two-part tariff competition in duopoly

    (Department of Economics and Finance, La Trobe University)

Built on the location model, this paper studies the rivalry of two firms in an industry through two-part tariffs. It is found that kinky profit functions are responsible for the coincidence of imperfectly competitive equilibrium and cartelization outcome. A duopoly likely results in higher entry fees and industry profits and lower net consumers surplus than a monopoly because each duopolist has a smaller market size than the monopolist. But social welfare in the monopoly is lower than in the duopoly. In comparison with uniform pricing, two-part tariffs tend to have lower prices, more profits and welfare but the magnitude of net consumers surplus is ambiguous.
