Brett Hollenbeck's research focuses on empirical industrial organization and quantitative marketing. His recent studies have looked at economies of scale in retail and service industries, the relationship between mergers and innovation, the economics of online reviews and ratings on online platforms, the regulation of rating manipulation on these platforms, and the role of imperfect competition in optimizing taxation and regulation of the growing legal cannabis industry.

Before pursuing his Ph.D. in economics at the University of Texas at Austin, Hollenbeck worked as an economist in the Office of Tax Policy at the U.S. Department of the Treasury and as a research fellow at the U.S. Chamber of Commerce. He teaches Customer Assessment and Analytics at Anderson, equipping his MBA students with quantitative tools to measure customer preferences and use models to analyze data.

Originally from Missouri, Hollenbeck is a film buff (foreign and Western), an avid traveler and a big supporter of Texas Longhorns football.
