Abstract:Abstract. This paper extends Matsushima and Matsumura (2003) by incorporating a large production cost difference between public and private firms in a quantity setting spatial mixed oligopoly. The public and private firms first choose their locations in a linear market and then compete in quantities. It is shown that for a significant inefficiency of the public firm, all firms (including both public and private firms) agglomerate at the market centre.
“…And they consider the privatization of the downstream subsidiary while we consider the privatization of the upstream subsidiary. 4 Hotelling model is quite popular in analyzing mixed oligopoly market, see for example Cremer, Marchand, and Thisse (1991), Cardenas (2007), Heywood and Ye (2009), Inoue, Kamijo, and Tomaru (2009), Shuai (2017, and Kitahara and Matsumura (2013) .…”
Abstract:This paper examines a different way of privatization from existing literature. In a mixed duopoly Hotelling type model in which the public firm consists of multiple subsidiaries, instead of privatizing the public firm as its entirety, the government may privatize only one of the subsidiaries (for example the manufacturing subsidiary). We find that this kind of privatization always improves social welfare comparing to no privatization at all. And comparing to privatizing the public firm in its entirety, privatizing only the manufacturing subsidiary always results in larger consumer welfare and results in larger social welfare when transport cost or R&D cost is sufficiently large.

“…More recent work by Kitahara and Matsumura () introduces elastic demand to the mixed‐duopoly Hotelling model. Different from these works assuming firms engaging in Betrand competition, Cardenas () assumes that firms engage in Cournot competition in a Hotelling‐type model. What distinguishes our paper from existing literature is that we allow the two firms, public and private, to engage in subcontracting.…”
Existing literature on mixed oligopoly focuses on competition among different types of firms but ignores their possible cooperation. We allow cooperation between a public firm and a private firm through subcontracting in a Hotelling mixed-duopoly model. We find that when subcontracting is possible, the equilibrium without subcontracting is not socially optimal because subcontracting can lower total production costs. And if both firms engage in subcontracting, the existence of a public firm can guarantee the first best equilibrium, whether it is the low-cost firm or not. But when a private firm is the low-cost firm, it is more profitable for it to choose vertical foreclosure. And the consequent equilibrium is not socially desirable anymore.
