This ambitious Handbook covers the history, functioning and impact of cohesion policy, arguably the most tangible presence of the European Union in its twenty-eight member states. The contributions combine world-renowned scholars and country experts to discuss, in six parts, the policy's history and governing principles; the theoretical approaches from which it can be assessed; the inter-institutional and multi-level dynamics that it elicits; its practical implementation and impact on EU Member States; its interactions with other EU policies and strategies; and the cognitive maps and narratives with which it can be associated. This Handbook will be an invaluable resource to students and scholars of EU policies and politics and other related disciplines. In particular, they will benefit from the clarity with which the history and functioning of cohesion policy is laid out. Policy makers and other practitioners will also find this book of interest, due to its presentation of relevant debates.
