Humanity needs a new economic theory, rather than a new public policy based on old theory, to guide us toward sustainability. This book provides a systematic critique of neoclassical economic approaches and their limitations with respect to sustainability. Leading institutional economists discuss theoretical perspectives about appropriate institutions for sustainable forest management, markets for environmental services, deforestation and specialization, and experiences of the Kyoto Protocol, international trade, biodiversity conservation, and sustainable forest management in general. The second volume in the series includes ideas from old and new institutional economics and discusses the main features of Post-Newtonian economics.
