Nelson Bills joined the Cornell faculty in 1985 after an 18-year career with the USDA's Economic Research Service. He conducts research and extension programs on a variety of subjects related to rural land use and public policy. A particular interest is land and water issues encountered in farm and food production. His research program focuses on state and local farmland protection programs, property taxation, farmland markets and values, and regional economic analysis. Current projects also deal with prospects for agricultural-based economic development, landscape management concerns in the Northeastern U.S., and assessment of behaviors in residential property markets.
