In her current research, Professor Seim studies the role of consumer inattention in firm pricing and competition in online markets. She analyzes how firms make product introduction, market entry, and pricing decisions in response to public policies involving subsidization, entry and technology deployment regulations, competition, and tax.

Professor Seim’s work also evaluates how market power affects government efforts to efficiently procure goods and services and sell assets. She has substantial expertise in the economics of price setting, including price discrimination and nonlinear pricing, particularly in the context of communications and information industries.

Professor Seim’s work has appeared in leading academic journals, such as the American Economic Review, Econometrica, Marketing Science, and the RAND Journal of Economics. She is a coeditor of the American Economic Review, and formerly coedited the RAND Journal of Economics.

Professor Seim is a research fellow at the Centre for Economic and Policy Research (CEPR) and the Mannheim Centre for Competition and Innovation, and a research associate at the National Bureau of Economic Research (NBER). She is a nonresident fellow in the Economic Studies Program at the Brookings Institution.

At Yale, Professor Seim teaches courses on industrial organization, probability modeling and statistics, and regulation. She previously served on the faculties of the Wharton School, University of Pennsylvania, and the Stanford Graduate School of Business.
