The Ministry of Economy, Trade and Industry requested a study on the use of economic analysis in business combination examinations in Japan and other major countries.

NERA conducted comparative research on the basic policies, guidelines, and implementation of business combination examinations in Japan and overseas, as well as the utilization status of economic analysis. Our study also investigated regulatory status and published cases regarding business alliances in Japan, the United States, and Europe.

Our suggestions were summarized for corporate practice and policy.
