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

From 2007 to 2012 I worked at the Stockholm Environment Institute’s U.S. Center, often in collaboration with Elizabeth A. Stanton and Ramòn Bueno.

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 Grist., among others 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.

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.
