演習（Big Tech and competition law）
How Has Competition Law Dealt with GAFA?
Google, Amazon, Facebook and Apple play an important role in the digital economy and in our daily lives. But the rapid growth and market power of these companies has also raised concerns. Have these companies become digital monopolies that threaten competition? Have they abused their market power to exclude smaller competitors? Have they engaged in “killer acquisitions”?
This seminar will look at how competition law - known in Japan as antimonopoly law 独占禁止法 - has dealt with these questions. The core of the seminar will be an analysis and discussion of the main cases that have been brought against Google, Amazon, Facebook and Apple. What was at issue in these cases? What has been the impact of these cases? The focus will be on cases brought by the European Commission, which enforces EU competition law, but cases brought by U.S. authorities and the Japan Fair Trade Commission can also be discussed.
