Outline of Final Research Achievements

This research explores economic impact of antimonopoly laws through the case
studies of recent court and tribunal decisions. Our research focuses on an increasing number of antitrust cases regarding unilateral conducts, coordinated conducts and mergers by multinationals, which provokes fresh concerns for declining competition and persistent supra-normal profits among them. We also examine the digital economy posing many unsolved challenges for competition authorities: merger control for data collection; collusion using algorithms; vertical restraints and exclusion in e-commerce; jurisdictional disputes and extra-territoriality; privacy and security policy on the internet, to name a few. Our research suggests that the recent case laws become economically reasonable, although digital economies pose many unsolved issues to be clarified in future research.
