This book argues that mainstream economics, with its present methodological approach, is limited in its ability to analyze and develop adequate public policy to deal with environmental problems and sustainable development. Each chapter provides major insights into many of todays environmental problems such as global warming and sustainable growth. Building on the strengths and insights of Post Keynesian and ecological economics and incorporating cutting-edge work in economic complexity, bounded rationality and socio-economic dynamics, this book provides an interdisciplinary approach to deal with a broad range of environmental concerns. The contributors show how and where the two traditions share common ground concerning environmental problems and shed light on how the two schools can learn from one another. The book will be of great value to Post Keynesian and ecological economists as well as to those interested in new approaches to important global environmental issues.
