Claus Kastberg Nielsen


Dr Claus Kastberg Nielsen helps private and public sector clients to reach favourable outcomes in antitrust matters, mergers, state aid, damage claims, and cases concerning regulatory design and management.

Claus is the founder of Copenhagen Economics and heads our Dispute Support service, acting as an expert witness in court cases of these matters.

His international experience spans the network and service sectors, including industrial production, agriculture, construction and retail.

Claus’ breadth of experience and expertise has helped clients in a wide variety of cases. One such example is that of Norwegian dairy producer Tine, where Claus helped to counter a claim of abuse of dominant position in the Norwegian dairy markets.

The Global Competition Review’s 'Who’s Who Legal' features Claus as one of the world’s leading competition economists.

I have great experience in providing and communicating clear results to Nordic and European competition authorities and as an expert witness to courts
