Competition regime: EU Market definition
The concept of the relevant market plays a central and often critical role in the application of EU competition law. The definition of the relevant market features in all decisions made under Articles 101 and 102 of the Treaty on the Functioning of the European Union and the EU Merger Regulation. The market definition adopted by the European Commission often has a decisive bearing on the outcome of a particular inquiry. This Practice note describes the economic principles used by the Commission to define markets and the type of evidence that can be used in such definition. It provides a checklist of points to consider in establishing a workable market definition.
