Neva Goodwin, Co-Director

Neva Goodwin is active in a variety of attempts to systematize and institutionalize an economic theory – “contextual economics” – that will have more relevance to contemporary real-world concerns than does the dominant economic paradigm. She has edited more than a dozen books, and is the lead author of three introductory textbooks: Microeconomics in Context, Macroeconomics in Context, and Principles of Economics in Context. A Transitional Economies Edition was translated into Russian and Vietnamese, and a European edition of the macro text is being prepared.

Over the past decade, Dr. Goodwin led the creation of a “social science library” called Frontier Thinking in Sustainable Development and Human Well-Being which contains nearly 10,000 full bibliographic references, representing seven social sciences, and including full text PDFs for a third of the referenced articles and book chapters. This is being distributed widely in 100 developing and transitional countries, with special efforts to reach institutions with poor or no Internet access. The goal is that this will also be available online through Tufts in early 2017.

Dr. Goodwin seeks ways to translate an understanding of the economy in its full social and ecological contexts into action and policy. She also seeks a deeper theoretic understanding from exposure to on-the-ground experiments in alternative socio-economic institutional design, and is involved with efforts to motivate business to recognize social and ecological health as significant, long-term corporate goals.

Some of Dr. Goodwin’s papers that receive continuing attention include:
Core Support for the New Economy [Draft working paper] June 2016
Prices and Work in The New Economy, April 2014
Five Kinds of Capital: Useful Concepts for Sustainable Development, September 2003

Dr. Goodwin received an MPA from Harvard Kennedy School (’82) and a Ph.D. in Economics from Boston University (’87). For more about Dr. Goodwin, see her Wikipedia entry and her ResearchGate profile, where several of her articles and working papers are also available.

William Moomaw, Co-Director

William R. Moomaw is Emeritus Professor of International Environmental Policy and Founding Director of the Center for International Environment and Resource Policy at The Fletcher School, Tufts University. He is also Co-Director of the Global Development and Environment Institute at Tufts. He received his BA degree in chemistry from Williams College and PhD in physical chemistry from MIT. Following a 26-year career in chemistry and environmental studies at Williams College, where he directed the Center for Environmental Studies, he began working on science diplomacy and climate change.

His research and teaching address climate change and low-carbon renewable energy and related global issues including water, forests, agriculture, nitrogen pollution and oceans. He has also developed the field of Sustainable Development Diplomacy as a means of implementing sustainable development and the Sustainable Development Goals. His current research examines the full range of fossil fuel consequences, the role of Restorative Development in removing carbon dioxide from the atmosphere by forests, wetlands, grasslands and agricultural soils, and correctly accounting for emissions from bioenergy.
