Online seminar on the Economics of Platforms

April 14, 2020 Research

The online Economics of Platforms Seminar will meet fortnightly.

Hosted by TSE Digital Center, this virtual seminar series is focused on the economics of platforms. Seminars can cover all aspects related to the economics of platforms including, for example, competition, strategy, design, governance, and policy issues. We hope to attract a good mix of applied theory, empirical papers, and policy discussions.
