Research

Kahn's research focuses on environmental, urban, real estate and energy economics. He investigates the causes and effects of urban economic growth^[1] and related issues of quality of life in cities. He has conducted and published research on public transit, sprawl, and the costs and benefits of environmental regulation in urban settings,^[6] as well as a comparison of the carbon footprints of different cities and investigation of how people living in cities are adapting to climate change.^[7] He is also known for his work on social capital.^[8] He blogs on these topics at greeneconomics.blogspot.com.
