This summer school is dedicated to some of the central questions in platform economics, their application to competition cases and the ensuing formulation of competition policy.
The lectures, given by Prof. Kai-Uwe Kühn, former Chief Economist of DG Competition, explore three central topics: Vertical restraints, competition between marketplaces, and two-sided markets. They focus on the exposition of the theory, adding empirical evidence and examples from competition cases.
The lectures are supplemented by empirical and legal clinics. The empirical clinics explore a particular empirical problem and expose a key method through lecture, demonstration and discussion. The legal clinics deepen the understanding of each lecture through an in- depth discussion of case(s) with a panel led by at least one lawyer and one economist.
The first lecture is dedicated to a review of the theory of vertical restraints and related evidence because a thorough understanding of vertical restraints is critical for many platform cases. The second and third lectures are devoted to two important externalities in platform markets that fundamentally affect antitrust analysis: externalities between different sellers on a marketplace and externalities between different customer groups on a multi-sided platform.
