'Remarkable, theoretically challenging, and rigorously conceived and researched, this outstanding volume cuts across existing IR theory paradigms to deliver the most cutting edge contribution to date to the comparative study of the design and efficacy of regional international institutions.' Emanuel Adler, Andrea and Charles Bronfman Professor of Israeli Studies, University of Toronto

'This comprehensive collection applies institutional design theory to the analysis of comparative regionalism. It thus enhances and deepens our understanding of an increasingly regional world. Sharp in its three analytical essays and rich in its five empirical case studies, the uniformly excellent chapters make this collection much more than the sum of its parts.' Peter J. Katzenstein, Walter S. Carpenter Jr Professor of International Studies, Cornell University

'In this examination of how institutions resolve regional cooperation problems, a top-flight range of authors deploy serious area studies knowledge within a rich and carefully crafted analytical framework. The book should be of a great interest to both general IR scholars and to regional specialists. A winning combination.' Andrew Hurrell, Director, Centre for International Studies, Oxford University
