Research Statement

Professor Stephan Seiler’s research focuses on analyzing consumer choice in various markets. He analyzes issues ranging from the choice of hospital for a bypass operation to the reaction of consumers to promotions on laundry detergent. He is particularly interested in understanding consumer search behavior, i.e., how informed consumers are about prices or other product characteristics when making a purchase decision. Another strand of research analyzes the production and impact of user-generated content on platforms such as Wikipedia and Twitter.


Professor Seiler received a PhD in Economics from the London School of Economics and joined Stanford GSB in the summer of 2011. From 2008 to 2010 he served as a teaching fellow at the LSE. In this capacity he taught both Microeconomics and Industrial Organization and Competition Policy to graduate students. During his studies he worked at various think tanks such as Deutsche Bank Research. He also served a stint at the Office of Fair Trading, the UK-equivalent of the FTC, analyzing the effects of market power on productivity and innovation. At Stanford he teaches Data and Decisions and Applied Econometrics for Public Policy.
