Personal profile


I am a Professor of Competition Economics. My research maps around various issues in law and economics, and competition economics. My current work includes the evaluation of the distributional impact of competition policy, and the consumer impact of autonomous recommendation systems. In previous works I have addressed topics such as deterrence, reputation, and private sanctions, and have published several papers and done consultancy works on ex post estimating the impact of competition policy. In my work I explore novel methodological tools such the use of machine learning methods for social science research. I have published in both economics and law journals of international excellence.

Beside my academic achievements, I have several years of policy analysis experience working for the Hungarian Competition Authority and the OECD.

I am a member of the Competition and Markets Authority's Academic Board.

I have provided advice and delivered various reports for the European Commission, the OECD, UNCTAD, and the World Bank on issues related to economic impact evaluation and the estimation of the consumer benefits of competition policy. Some of these are publicly available:

Key Research Interests and Expertise

My research is mapped around various topics in law and economics, including the analysis of the effect of private sanctions, measuring cartel detection and deterrence, the anti-competitive effects of mergers, and the ex post evaluation of the impact of competition enforcement including the analysis of the deterrent effect of law enforcement. I am currently working on more general questions of law and economics, such as the reputational effects of crime. I generally welcome PhD applications on any of these wider areas. Methodologically I am currently exploring how machine learning can contribute to studying social sciences, and especially competition law and economics.

Teaching Interests

At undergraduate level I teach Economics for Business and Economics for International Business. I am module organiser for the MBA module International Economic Environment.
