【摘要】This paper is the first to investigate the impact of the presence of a public firm on the profitability of two-firm mergers in a spatial price discrimination model. The presence of the public firm may increase the set of mergers for two private firms to profitably merge. Merger increases social welfare in the presence of a public follower alone. However; privatizing the public firm never increases social welfare.
