The debate around whether or not antitrust tools need to be adapted to the digital economy continues across major jurisdictions. Antitrust and big tech has become a political issue in the US Presidential campaign as well as with a new European Commission taking shape in Europe. The following questions will be addressed: • What are the implications for future enforcement of the various hearings and studies we are seeing, including at the US FTC and by Commissioner Vestager’s special advisers? • How should we think about online platforms and vertical integration, which is an issue being investigated on both sides of the ocean. • Is there an antitrust theory of harm around self-favouring? The discussion continues around the data economy and data sharing as an antitrust remedy: • Do we need new tools or theories of harm to address network effects and ‘tipping’ markets? • How do we look at defining relevant markets and market power in view of competition between ecosystems, competition for attention, two/multi-sided platform markets, an increasing focus on non-price effects, and data privacy as an element of product design? This panel gathers leading experts from regulators, private practice, corporates and academia to give their different perspectives on digitalisation.
