Co-operative and mutual enterprise is one of the oldest and most enduring forms of business, encompassing co-operatives, mutual firms, friendly societies, and credit unions. This book provides an expert overview of contemporary research in this important field. Governments around the world have encouraged the development of co-operative and mutual enterprises (CMEs), yet relatively little attention has been given to them within the mainstream business and economics research literature. In this book, the author summarises the origins, impacts, and structure of the research field. The book does so by focusing on the CME business model and is structured around a conceptual framework for research into CMEs. It also explores the historical evolution of the CME research field and presents a systematic review of the literature. Foundation theories relevant to CMEs are discussed before detailed discussions of the research from a systems, enterprise, and member level perspective. This book critically analyses the state of knowledge in the field of CMEs which delivers a concise and valuable book for scholars and students in the fields of business and management around the world.
