Joseph is an experienced competition economist and qualified accountant providing advice on litigation, antitrust, market investigations and mergers. He has a particular specialism in matters that require the application of empirical analysis, such as econometrics, to assess underlying competition issues or harms. He is one of Oxera’s leading advisers in the area of follow-on antitrust litigation. Able to work across jurisdictions, Joseph has led projects providing evidence to competition authorities (including the CMA and European Commission) and a number of national courts.

An experienced communicator, one of Joseph’s core skills is making complex economics concepts practical, relevant and clear, and he has experience of providing expert testimony in the UK and to the European Commission. He is a trainer on Oxera’s established Economics for Competition Law course, providing economics training to solicitors, barristers and in-house counsel across Europe. He has also delivered EU-sponsored courses on the quantification of competition damages for member state judges.

Providing advice across a wide range of industry sectors, Joseph has particular experience working in the fields of payments services and telecoms. Prior to joining Oxera, Joseph worked for four years in BT Group’s finance division, where he received his accountancy training. He also conducted an econometric research project at the Bank of England.
