Martin Peitz Can Multiple Platforms Profitably Co-Exist in Digital Markets?
Martin Peitz is Professor of Economics at the University of Mannheim and co-director of the Mannheim Centre of Competition and Innovation (MaCCI). His research focuses on theoretical industrial organization and ongoing projects include work on non-standard consumer behavior and regulation and competition issues in digital markets. He holds research fellowships with the Centre on Regulation in Europe (CERRE) and the Economics Network for Competition and Regulation (ENCORE) among others. The second edition of Peitz’s book Industrial Organization: Markets and Strategies (co-authored with Paul Belleflame) was published in 2015.

In the internet age, digital platforms are providing increasingly important settings for buyers and sellers to interact. In this video, MARTIN PEITZ investigates why some markets tend to be dominated by single platforms (e.g. Google for internet search) while others (e.g. hotel booking) allow multiple platforms to profitably co-exist. Using theoretical modeling, the research indicates that sellers in particular markets may prefer to locate themselves in distinct platforms in order to reduce the intensity of competition. Enhancing our understanding of how digital markets function, Peitz’s work provides valuable underpinning for future competition policy.
