I am a Professor in the Dept. of Economics at Georgia State's Andrew Young School of Policy Studies. I am also a Research
Associate at the National Bureau of Economic Research (NBER) and a Senior Research Fellow at the Property and Environment Research
My primarily field of study is environmental policy analysis, especially related to the urban environment and to issues related to
air pollution and energy. One common theme in my work is the interactions among local environmental amenities, local real estate markets,
and the demographic composition of cities. For example, I have studied the way these social mechanisms interact to drive the correlations
between pollution and poor households, as described by the "Environmental Justice" movement.
I also use tools from these models to gain insights into people's values for the natural environment and for other public goods that
are not traded in markets. Whenever people pay more for a house because it is in a cleaner, safer community with good schools, they
reveal something about their values for a clean environment, safety, and education. I apply such insights to benefit-cost analysis
and to the design of environmental policies. In other work, I have similarly applied such tools to "green accounting" (that is, to
reforming GDP and similar statistics so they account for the environment). In related work, I have suggested ways to measure and
construct indexes of ecosystem services.
Finally, I conduct research into the history of applied welfare economics and other applied economics, primarily focusing on the
early to mid 20th century. I find this history fascinating in itself, but also a complementary tool for policy analysis. For example,
lessons from earlier struggles with creating an architecture for measuring income (GDP), inflation (CPI), and for project benefits
(benefit-cost analysis) provide valuable lessons for public policy today.
My research has been published in such journals as the American Economic Review, International Economic Review, Journal of Applied
Econometrics, Journal of Public Economics, Journal of Environmental Economics and Management, Journal of Urban Economics, and
History of Political Economy. It has been funded by such agencies as the National Science Foundation, the Environmental Protection
Agency, and the Lincoln Institute of Land Policy.
I teach Microeconomic Theory as well as Environmental Economics to PhD students and an Introduction to Microeconomics to undergraduate students.
I received my PhD in economics from Duke University in 2001. Before coming to GSU, I was a fellow at Resources for the Future (RFF).
