What are the key challenges digital markets pose for competition authorities, and how can they navigate this complexity? In this video, Renato Ferrandi (Director of International and EU Affairs, Italian Competition Authority), Antonio Capobianco (Deputy Head, OECD Competition Division), and Gábor Gál (Member of the Competition Council, Hungarian Competition Authority) explore the main digital challenges for competition policy. Their discussion builds on insights from the Competition Lab for Judges, organised by the OECD-GVH Regional Centre for Competition in Budapest in May 2023, with financial support from the European Commission.
