This Handbook is remarkable for the breadth and quality of its contributors. Kudos to the Editors for assembling such a comprehensive collection of chapters on cooperatives and mutuals theory, governance, and practice. -- Brent Hueth, U.S Department of Agriculture, Washington DC, US Cooperatives define a multidimensional, complex set of organizational arrangements. This Handbook mobilizes an impressive group of experts to review the nature, role, governance, and diffusion of cooperatives worldwide, whilst exploring the numerous problems they face. It is a must-read for researchers and students as well as practitioners. -- Claude Menard, University of Paris, France Cooperatives and mutuals are a significant part of the economic landscape in most countries, but we have lacked a comprehensive source for knowledge and understanding of them and their potential to improve economic outcomes for members. This book, comprised of contributions from a distinguished group of international scholars and practitioners, fills this need and is an indispensable reference for researchers, practitioners, and policymakers. -- Richard Sexton, University of California, Davis, US
