The Rise of Ecosystem Theories: Where are we after Microsoft/Activision and Booking/etraveli?

By UCL Laws (other events)

Tuesday, October 31 2023 5:30 PM 7:45 PM BST

The “ecosystem theory of harm” was a major focus of the CMA’s investigation of Microsoft/Activision, which has just been approved with revised undertakings. The EC recently blocked Bookings/eTraveli on “ecosystem” grounds. And beyond mergers, new antitrust complaints (Amazon) have a strong “ecosystem” flavour.  How does one articulate such a theory, and what should be the standard of proof?  What economic work do we need to make it more durable?
