First published in 1999, this work of economic history explores the evolution of the single market and of economic and political integration in Europe since World War II. Beginning with European integration and the genesis of the Customs Union, Bill Lucarelli then proceeds through the Trans-Atlantic Rivalry, the European Monetary Union (EMU) the European Monetary System (EMS) and on to Maastricht. The study intends to be a critique of the prevailing theories of negative integration, weighting economic integration against political integration, with a particular focus on the concept of ‘spill-over’. Lucarelli argues against prevailing functionalist and neo-liberal interpretations of the process of economic integration. The conclusion is critical of the strategy toward European Monetary Union. The book is informed by Marxian and Post-Keynesian Economic theories.
