Book excerpt: This is the twelfth in a series on EU Competition Law and Policy produced by the Robert Schuman Centre of the European University Institute in Florence. The volume reproduces the written contributions and transcripts in connection with a roundtable debate which examined the EU's enforcement policy as regards the abuse of a dominant position under Article 82 EC. The workshop participants included: senior enforcement officials and policy makers from the European Commission, from the national competition authorities of certain EU Member States and from the US Department of Justice and Federal Trade Commission; and renowned international academics, legal practitioners and professional economists. In an intense, intimate environment, this group of experts debated a number of legal and economic issues structured according to three broad lines of discussion: 1) comparisons of the concept of monopolization under Section 2 of the Sherman Act with that of abuse of dominance under Article 82 EC; 2) a reformed approach to exclusionary unilateral conduct; and 3) exploitative unilateral conduct and related remedies.
