Most of my work since 2007 has been on the economics of climate change and energy, often in collaboration with Elizabeth Stanton and Ramòn Bueno. See also the website of the Stockholm Environment Institute’s U.S. Center, where I worked from 2007 to mid-2012.
Most of my work from 2000 to 2006 focused on cost-benefit analysis and regulations, with applications to toxic hazards and chemicals policy. Lisa Heinzerling and Rachel Massey were frequent coauthors.
In the same years I also examined the economic and environmental impacts of globalization and trade liberalization, with Kevin Gallagher and other coauthors.
Writing on economic theory and methods was a major focus in the late 1990s, often in collaboration with Neva Goodwin and others at Tufts University’s Global Development and Environment Institute (where I worked from 1995 to 2007).
Earlier in the 1990s, my work centered on the economics of waste and recycling. Selected publications are listed here; many of my studies in this area, done at the Tellus Institute, are available only in hard copy.
A final area of interest - a short list of publications for now - involves macroeconomics and crisis.
It has unfortunately become necessary to add a page responding to Richard Tol's attacks on my work. Please read and sign the economists' statement of support for my work, found on that page.
