Privatizing Multi-Subsidiary Public Firm in Location Model

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 multi-subsidiaries, instead of privatizing the public firm as its entirety, the government may privatize only one of the subsidiaries (for example the manufacturing subsidiary).
