Seminar Series

2021 - 2022

Speaker: Andrea Mantovani (TBS).

Title: “Regulating Platform Fees under Price Parity”

joint with Renato Gomes (TSE).

Date: Thursday, January 6th at 12h30 (Paris Time).

Abstract: Online intermediaries greatly expand consumer information, but also raise sellers’ marginal costs by charging high commissions. To prevent disintermediation, some platforms adopted price parity and anti-steering provisions, which restrict sellers’ ability to use alternative sales channels. Whether to uphold, reform, or ban these provisions has been at the center of the policy debate, but, so far, little consensus has emerged. As an alternative, this paper studies how to cap platforms’ commissions. The utilitarian cap reflects the Pigouvian precept according to which the platform should charge net fees no greater than the informational externality it exerts on other market participants.
