Associate Professor of Economics

(On leave 2007-2008)

Professor Keohane's research concerns the theory and practice of environmental policy. His current research focuses on how market-based policies such as cap-and-trade programs affect the adoption and innovation of new methods to control pollution. Other projects include hedonic estimation of the value of clean air, and a study of how firms respond to the threat of regulatory enforcement. Professor Keohane is on leave for the academic year 2007-2008, working as a senior economist on climate change policy at Environmental Defense, a non-profit advocacy organziation based in New York.
