This website pulls together my work on a range of issues in economics and environment. It emphasizes publications since the mid-1990s; most of my earlier writing is not available in electronic form.

Most of my work since 2007 has been on the economics of climate change and energy. See also the website of the Stockholm Environment Institute’s U.S. Center, where I worked from 2007 to 2012, often in collaboration with Elizabeth A. Stanton and Ramòn Bueno.

Since 2012 I have been at Synapse Energy Economics; some of my recent reports appear on the Synapse website but not here.

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.

My blog posts have appeared on Triple Crisis, Real Climate Economics, CPRblog, and occasionally on Grist. I don’t do Twitter or Facebook.

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.

On a very different note, my wife, Becky Sarah, has written an excellent book, Grandmothering: Real Life in Real Families. I recommend it, for anyone who is or knows a grandmother.
