John Davies is an Executive Vice President with Compass Lexecon, based in Paris and London. He began his career in 1994 as a consulting economist specializing in regulation and competition, working on mergers (such as HP/Compaq), regulatory reviews in gas, electricity and airports and privatization of utilities.

John returned to consulting in 2016, after 12 years of working in several public sector roles. He was Director of Economic Analysis and then Chief Economist at the UK Competition Commission (CC) from 2003 – 2008, leading the CC’s team of economists and responsible for economic analysis on all the CC’s cases, including the major Groceries, Airports and Payment Protection Insurance market investigations, merger investigations such as BSkyB/ITV, Somerfield/Morrisons and rail franchise mergers, as well as regulatory reviews in energy, telecoms and transport. John left the UK CC in 2008 to found the Competition Commission of Mauritius where, as Chief Executive, he established the organization and led it through its first years of enforcing the new competition law in Mauritius.

In 2011, John moved to head the OECD’s competition division. He led the team in organizing regular ‘roundtable’ meetings of competition agency heads from around the world, including supervising the analytical papers produced for those events. John also led the OECD’s capacity-building programs for newer agencies in Asia and Eastern Europe and advised Governments at ministerial level on competition policy.

At Compass Lexecon, John has advised clients on a wide range of competition matters, with a particular focus on pharmaceuticals and the tech sector. He has advised on Phase I merger investigations by the UK CMA and DG Competition, as well as Phase II mergers in Brussels. He has advised clients both defending against and bringing claims of abuse of dominance in the UK and Brussels and is an expert witness in follow-on claims arising from the E.C. power cables cartel case. He was also co-author of a major report on the competitive effects of standard-setting organizations. He is joint head of Compass Lexecon’s London office.
