Class of 1934 Robert Gordon Sproul Distinguished Professor in Agricultural Economics and Professor of Agricultural and Resource Economics | Department Chair
Sofia Berto Villas-Boas is a professor in the Department of Agricultural and Resource Economics at U C Berkeley. She holds the Class of 1934 Robert Gordon Sproul Chair in Agricultural Economics. Born in Portugal in 1971 she received her Ph.D. in Economics from U. C. Berkeley in May 2002 and an undergraduate degree in Economics from the Universidade Católica Portuguesa. She teaches Econometrics in the ARE Ph. D. program and in the undergraduate major of Environmental Economics and Policy at the Rausser College of Natural Resources. She has published in top economics and field journals such as Review of Economic Studies, Rand Journal of Economics, American Journal of Agricultural Economics, Journal of Environmental Economics and Management, Marketing Science, Management Science, and Review of Economics and Statistics.
Her research interests include industrial organization, consumer behavior, food policy, and environmental regulation. Her recent empirical work estimates the effects of policies on consumer behavior, such a bottled water tax, a plastic bag ban, and a soda tax campaign and its implementation. Other published work has focused on the economics behind wholesale price discrimination banning legislation, contractual relationships along a vertical supply chain, and identifying the role of those contracts in explaining pass-through of cost shocks along the supply chain into retail prices that consumers face.
