Ashley Langer

Associate Professor of Economics,
Eller College of Management,
University of Arizona

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). Lexology Index (formerly Who’s Who Legal) has named Professor Langer a Future Leader among global competition experts and has also recommended her as a leading competition economist and consulting expert.

At the University of Arizona, Professor Langer teaches courses in business strategy, empirical research methods, environmental economics, energy and environmental policy, and government regulation.

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.

Antitrust and Competition Capabilities

Our experience in matters involving allegations of anticompetitive horizontal conduct includes cases in which plaintiffs alleged price fixing, agreements to allocate territories or customers, or group boycotts. We have worked on major cases for the joint defense and for individual clients including recent cases involving labor markets, payment cards, energy, pharmaceuticals, financial instruments, and auto parts. In these and other assignments, we have assessed the economic incentives of the alleged participants, tested hypotheses that distinguish competitive from collusive behavior, and assessed the likelihood and quantum of damages.

We have analyzed claims of monopolization, tying, exclusive dealing, and anticompetitive pricing practices, such as loyalty or volume discounts and bundled rebates. We have assessed whether these practices can be attributed to competition among firms, are the result of hard bargaining between buyers and sellers, and have efficiencies that outweigh any potential harm to competition. Our recent experience includes cases involving high-technology products and services, pharmaceuticals, and health insurance.

Cornerstone Research has worked on many direct and indirect purchaser class certification matters. Our case experience and analytical breadth enables us to meet the changing demand for rigorous empirical and conceptual assessment of both the questions of common impact and common proof and of the merits issues that bear on those questions. Recently, we have assisted counsel in antitrust matters involving mobile devices, pharmaceuticals, and employment practices.

We have analyzed the potential competitive effects of horizontal and vertical mergers in the context of the early stages of potential deals, enforcement agency reviews, government litigation and private litigation, in the United States, Europe, and other jurisdictions. We have applied economic theory and quantitative economic methods to define relevant markets, identify close competitors, determine competitive interactions, analyze potential price impacts and potential for foreclosure, and assess whether there are efficiencies associated with the proposed collaboration.

We are also experienced at assisting clients with complying with Second Requests, in a manner that is both efficient and fully responsive to the agency’s request.

Cornerstone Research experts have testified on matters involving failing firm defenses and exiting assets arguments in a number of industries, including healthcare, finance, and technology. Our experts have assisted antitrust authorities in evaluating the merits of failing firm claims and consulted to merging parties arguing the failing firm defense affirmatively. Assessing failing firm arguments from both the enforcement agencies’ and merging parties’ perspectives gives us distinct insight into the rigorous demands of this defense.
