Author Description

The notion of market power is central to antitrust law. Under EC law, antitrust rules refer to appreciable restrictions of competition (Article 81(1) EC), the elimination of competition for a substantial part of the market (Article (81(3) EC), dominant positions (Article 82 EC) and substantial impediment to effective competition, in particular by creating or reinforcing a dominant position (Article 2 of the EC Merger Regulation). At first sight, only the concept of dominant position relates to market power but it is the aim of this book to demonstrate that the other concepts are directly linked to the notion of market power. This is done by reference to the case law of the EC Courts and the precedents of the European Commission and the author goes on to argue that for very good reasons (clarity and enforceability, among others) the rules should be interpreted in this way.Beginning with market definition, the book reviews the different rules and the different degrees of market power they incorporate. Thus it analyses the notion of 'appreciable restriction of competition' to find a moderate market power obtained by agreement among competitors to be the benchmark for the application of Article 81 EC. It then goes on to the concept of dominance under Article 82 EC, which is equivalent to substantial (or important) market power and then focuses on the old and new tests for EC merger control. Finally, it addresses the idea of elimination of competition in respect of a substantial part of the market (ex Article 81 (3) (b) EC), in which the last two types of market power (ex Article 82 and Ex ECMR) converge. To exemplify this, an in-depth study of the notion of collective dominance is made.The book concludes that a paradigm of market power exists under the EC antitrust rules that both fits with past practice and provides for a useful framework of analysis for the general application of the rules by administrative and even more importantly judicial authorities in the Memb
