This book provides solid academic evidence of a lively debate and dialogue between US and EU scholars about Multilevel Governance (MLG) and Intergovernmental Relations (IGR). Beyond the contingencies of the terms and the path dependency of their historical developments, there are elements of convergence and overlap. This publication is a good example of how academic transatlantic dialogues result in a stronger understanding of the premises of our concepts, and of the functioning of our systems.' - Geert Bouckaert, Public Management Institute and European Group for Public Administration, Leuven, Belgium This book represents a major attempt to draw together two fundamental streams of research; Intergovernmental Relations and Multi-Level governance. Combining US and European schools of thought, this timely volume outlines key areas of convergence and divergence.
