Marca Weinberg returned to ERS as a senior economist in the Resource and Rural Economics Division (RRED) in September 2020. She previously served as Acting Administrator (2019-2020) and RRED director (2012-2019), and served earlier stints as associate director for RRED and chief of the division's Resource, Environmental, and Science Policy Branch. In her current position, she leads a program of research, analysis, and data collection to support policy makers and program managers concerned with the structure and performance of the farm sector, rural community development and well-being, conservation programs and implications of environmental regulations. Prior positions include assistant professor, University of California, Davis, Department of Environmental Sciences and Policy, and economist with the Congressional Budget Office. Her primary research focus was on estimating costs, benefits, and distributional implications of policy design options for addressing water use and water quality concerns associated with agricultural production.
