Mike Mazzeo became dean of WashU Olin Business School on September 1, 2023. He joined the Olin faculty as a professor of economics after a 25-year career as a researcher, scholar and educator at Northwestern University’s Kellogg School of Management, where he was a professor of strategy and a faculty associate at the university’s Institute for Policy Research. Mazzeo has had a distinguished and prolific career as a researcher, and his work—focused on empirical industrial organization—has been cited thousands of times.
Students have recognized Mazzeo with teaching awards numerous times for his work as a strategy instructor in Kellogg’s MBA and executive MBA programs. He served as faculty director for Kellogg’s evening and weekend MBA programs and its Master of Science in management studies program. He was the school’s senior associate dean for curriculum and teaching from 2017 through 2020.
As a scholar, Mazzeo has developed new statistical methodologies for examining the relationship between product differentiation and market competition, with insights spanning the airline, banking, healthcare, hospitality, retail and telecommunications industries and applications for both business strategy and antitrust analysis. He serves on the editorial board of the Review of Industrial Organization and is coauthor of Roadside MBA: Back Road Lessons for Entrepreneurs, Executives and Small Business Owners.
That 2014 book, a collaboration with fellow business professors from Stanford and the University of Utah, was based on visits with more than 250 small- and medium-size businesses over a dozen years. Covering more than 30 states and 12 countries, the team shared stories illustrating the important concepts taught in leading MBA programs.
