Building on empirical research and relevant literature, this book describes and analyzes sustainable economic alternatives and looks at their role in a world where the old paradigms of aggregate economic growth, free trade and perfectly competitive markets are fast losing their appeal. What do the eco-social enterprises do? How do they differ from the mainstream? What are the motivations and implications of their organisational and governance structures? How are they conceptualised from different ideological and geopolitical perspectives? This book addresses these questions and others about these new approaches to production, trading, consumption and finance.
