Spencer Banzhaf is a professor of agricultural and resource economics at North Carolina State University. Prior, he was a professor of economics at Georgia State University’s Andrew Young School of Policy Studies. He also is a research associate at the National Bureau of Economic Research and a senior fellow at the Property and Environment Research Center. Banzhaf’s primary field of study is environmental policy analysis, especially related to the urban environment (such as sprawl and land use) and to issues related to energy and air pollution. One common theme in his work is the interaction among local environmental quality, local real estate markets, and the demographic composition of cities, which together can drive the correlations observed between pollution and poverty, as described by the environmental justice movement. He received his Ph.D., M.A., and B.A. in economics from Duke University.
