Outline of Final Research Achievements

This research explores economic impact of the antimonopoly law through the case studies of recent court and tribunal decisions. In Japan, collaboration between legal scholars and economists, which sharpens the conception and way of thinking regarding enforcement, has not been so active as in Europe and the USA. Economic analysis is able to help with clarifying the universality and idiosyncrasy of the Japanese antimonopoly law. Hence we try extracting lessons and best practices from recent important court and tribunal decisions that have great impact on the case laws in Japan. Our research contributes to practitioners by reinterpreting and clarifying legal judgements and formulating reasonable code of conducts and guidelines for business people. Especially, it is important to scrutinize the validity of empirical evidences that are premises of sound legal judgements. Our research suggests that the recent case laws become economically reasonable, especially in collusion and merger.
