This new book examines the economic foundations of the European Union and seeks to give the reader a solid grounding of the core concepts that explain why EU law looks and works as it does. Law and Economics of the European Union emphasizes case law and comparisons to analogous doctrines and problems that arise in the implementation of U.S. federalism. The authors strike a balance between the "constitutional" aspects of the EU—the establishment and the delineation of the institutions, with emphasis on their powers vis-à-vis the states that make up the Union—and the regulatory product of the European Community, in particular the law that implements the freedom of movement of goods, services, persons, and capital. The final chapter looks at competition law in the EU, with multiple comparisons to U.S. antitrust law. This book reflects the authors' judgment that the EU, as an institution and the source of a body of law, has played, and will continue to play, an important role in contemporary international and business life.
