Josh Linn is a professor in the Department of Agricultural and Resource Economics at the University of Maryland and a senior fellow at Resources for the Future. His research centers on the effects of environmental policies and economic incentives for new technologies in the transportation, electricity, and industrial sectors. His transportation research assesses passenger vehicle taxation, electric vehicle subsidies, and fuel economy standards in the United States and Europe. He has examined the effects of Beijing’s vehicle ownership restrictions on travel behavior, labor supply, and fertility. Linn’s work on the electricity sector has compared the effectiveness of policy instruments in promoting new technology and reducing emissions of carbon dioxide and local air pollutants. He has compared the roles of natural gas prices and environmental regulation in explaining coal mine closures and the shift away from coal-fired generation in the United States. He has examined the implications of low-cost storage for reducing electricity sector emissions, as well as the factors driving electricity demand and implications for retail prices. Linn was a senior economist at the Council of Economic Advisers from 2014–2015, and he has served on a National Academies of Sciences, Engineering, and Medicine committee on light-duty fuel economy. He was a co-editor for the Journal of Environmental Economics and Management. He received his Ph.D. in economics from the Massachusetts Institute of Technology.
