Outline of Final Research Achievements

(1) We have examined the impact that a merger between a public firm and a private firm has on social welfare in a mixed oligopolistic market. We have simulated the comparison of social welfare before and after the merger between a public firm and a private firm to investigate whether the merger improves social welfare by specifying the functional forms of cost function.
(2) We have investigated the neutrality theorem on whether welfare is exactly the same before and after merging. We have shown that when regulating authorities can implement the appropriate subsidy policies to regulated firms, the privatization neutrality theorem can be satisfied in a broader economic environment. (3) We have analyzed the international harmonization of regulations. We have clarified that even if a country cares about other countries, income transfer from a transferor inhibits capital accumulation and the social welfare of the transferor is less likely to improve.
