Optimal privatization and uniform subsidy policies: A note


  • Ming Hsin Lin
  • Toshihiro Matsumura


The privatization neutrality theorem states that the share of public ownership in a firm does not affect welfare under an optimal uniform tax‐subsidy policy. We revisit this neutrality result. First, we investigate the case in which the private firm is domestic. We show that this neutrality result does not hold unless public and private firms have the same cost function. Next, we investigate a case in which both domestic and foreign investors own the private firm. We show that the optimal degree of privatization is never zero, and thus, the neutrality result does not hold, even when there is no cost difference between public and private firms.
