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 Center (PERC).
My primarily field of study is environmental policy analysis, especially issues related to the urban
environment, like air pollution and green space. One common theme in my work is the interactions among
local environmental amenities, 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 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.
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 supported
by the National Science Foundation, the Environmental Protection Agency, the Lincoln
Institute of Land Policy, and others.
I received my PhD in economics from Duke University in 2001.
