Professor Hildebrand supervises PhD thesis on digital platforms and competition
Sung Yoon Yang with co-supervisors Hildegard Schneider, Michael Faure and Doris Hildebrand
The thesis addresses regulation of abuse of a dominant position by multi-sided platforms and legislative efforts to prevent or restore the unfair competitive environment caused by gatekeeper platforms in the EU, the US, and Korea.
The study was written based on a ‘comparing’ methodology, using case analysis research methods, interviews and surveys, as well as a review of publicly available resources.
The thesis suggests a new three-phase model competition authorities can apply in regulating multi-sided platforms. For gatekeeper platforms, the thesis suggests pre-regulatory legislative measures and dominance abuse enforcement. For non-gatekeeper platforms in a dominant position, the thesis suggests dominance abuse enforcement. For non-dominant platforms, unfair trade practices enforcement might be applied.
Professor Hildebrand advised Sung Yoon/Ms Yang based on her own expertise as an academic at Paris Sorbonne University and as economic expert at EE&MC.
