Protecting economic competition has become a major objective of government in Western Europe, and competition law has become a central part of economic and legal experience. National competition laws have long helped shape the relationship between government and the economy, and their influence has grown dramatically during the last decade. Competition law has also played a key role in the process of European integration, and is likely to do so in the future. Yet, despite its importance, images of European experience with competition law often remain vague and are sometimes dangerously distorted. This book examines that experience, analysing the dynamics of European competition law systems, revealing their impacts and assessing the political and economic issues they raise.
