Mixed duopoly under hotelling with convex production costs

Dragone and Lambertini (Reg Sci Urban Econ 84:103568, 2020) show that in a Hotelling duopoly with linear transport cost, sufficiently convex production cost generates an elevated price equilibrium with collocation at the middle. We examine the consequences of a mixed duopoly under these cost assumptions. No equilibrium exists in a mixed duopoly with simultaneous location. Equilibria exist under location leadership. Private firm leadership generates greater welfare than public firm leadership, a result different from previous examinations. A mixed duopoly with a foreign firm generates an equilibrium with firms usually located apart but with the public firm serving all interior customers. This typically increases welfare relative to the fully private market.
