"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
"It is often argued that regional groupings of states are becoming more important in world politics, but it remains puzzling why regions have taken shape in such different ways around the world and how these differences matter. In this pathbreaking book on the logic and diversity of regional cooperation, Acharya and Johnston provide the best available answers yet to these puzzles....The book makes clear that the world's regions are not all following a single, Western-style trajectory; instead, they are evolving in unique ways to cope with distinct geographic, cultural, and geopolitical realities."
