Ashley Langer is an econometrics, energy, and industrial organization expert. Professor Langer applies sophisticated empirical methods to study regulation, competition, and firm and consumer behavior. She analyzes a range of economic issues, including those involving energy markets, transportation, and the environment. Professor Langer has testified on issues related to class certification and economic damages, including in such high-profile class actions as Guzman et al. v. Polaris Inc. et al. and Garcia et al. v. Volkswagen Group of America Inc. et al.
Professor Langer has analyzed consumer decisions, including those related to the automotive and oil industries. She has evaluated decisions on which vehicles to drive, how preferences form, when and where to purchase fuel, and whether to adopt electric vehicles. She has also investigated the impact of consumer demographic group preferences on vehicle pricing.
In her recent research, Professor Langer has assessed energy and environmental policy design issues. For example, she has analyzed international oil markets and the factors that influence pricing, as well as how Clean Air Act regulatory enforcement affects pollution levels and firms’ investment decisions. Further, she has studied the impact of energy policy on durable goods such as automobiles and residential solar. In particular, Professor Langer has examined how households respond to solar subsidies that change over time, how uncertainty surrounding policy enforcement affects coal power plant retirement and upgrade decisions, and how taxing vehicle mileage (rather than fuel consumption) changes Highway Trust Fund revenues. Her earlier work includes assessing the effect of congestion tolling on urban land use.
Professor Langer’s research has been published in leading academic journals, including the American Economic Review, the Journal of Public Economics, and the Review of Economics and Statistics. She is a research associate at the National Bureau of Economic Research (NBER).
At the University of Arizona, Professor Langer teaches courses in business strategy, empirical research methods, environmental economics, energy and environmental policy, and government regulation. She has been honored with several teaching and advising awards. In addition, Professor Langer presents on industrial organization and empirical research methods, as well as transportation, energy, and environmental topics, at professional conferences and universities in the United States and internationally.
Professor Langer previously taught at the Ford School of Public Policy at the University of Michigan. She was a visiting scholar at Columbia Business School and the Energy Policy Institute of Chicago, University of Chicago.
