| Outline of Final Research Achievements |
I take up some horizontal merger cases realized in 1990’s Japanese market, and compare the real price changes and the estimated result of merger simulation analysis. As a result, I find merger simulation have an overestimation bias to price change in Japan. In addition, in some Japanese differentiated market, I attempt market definition analysis using SSNIP test. However, I cannot find the boundary of the relevant market, and as a result, I cannot run the merger simulation analysis. Therefore, when we use the merger simulation analysis in Japanese market, we should be careful and restrictive to the role of supplement to usual competitive market analysis.
