This timely book explores the development of the European Social Model and questions whether the relatively high level of social protection provided, both in terms of social welfare provision and in the creation of workers rights and employment regulation, is sustainable. At the 2000 Lisbon Council the Member States agreed that this model was in need of modernisation if the objective of creating the most competitive and dynamic knowledge-based economy in Europe was to be achieved. Consequently, this book examines the economic rationale for EU social policy, identifies the main factors promoting reform and assesses the priorities for reform in the enlarged EU.As a result of a fruitful collaboration between two authors from different disciplines, and culminating in several contributions to the economic-legal analysis of the EU social policy, this forward-looking book will be of great interest to academics, EU policymakers and law practitioners.
