Empirical Effects of Competition Policies


Rhys is a PhD student in Economics at the University of Cambridge, supervised by Christos Genakos, Michael Pollitt and Kamiar Mohaddes. His research interests are in empirical IO, and he is currently researching the effect of quality ratings on consumer search in the healthcare sector. Future research ideas intend to investigate the application and effect of vertical restraints.

As a Director of the Workshop Series at the King’s Entrepreneurship Lab, an ecosystem designed to educate and inform future entrepreneurs, Rhys is involved in organising and facilitating workshops covering a range of entrepreneurial skills such as developing a pitch, marketing, hiring a team and exit options.

Rhys has over 5 years’ experience working in an economics consultancy, advising the EU, UK Government, and other organisations on matters of public policy. In particular, he was heavily involved in the EU DG Comp’s evaluation of the Vertical Block Exemptions Regulation, taking an empirical look at the effects of resale price maintenance in the book sector, and building a theoretical framework to consider the state of competition in the professional business services sector.
