We present a general and tractable oligopoly model of multi-sided platforms with endogenous side and platform choices of heterogeneous end-users, considering any mix of single-homing and multi-homing platforms and in which participating on one side could preclude doing so on others. We show the...

Large digital platform companies increasingly integrate vertically by building Internet infrastructure, such as edge computing facilities, content delivery networks, or submarine cables. These investments enable new services while changing their bargaining power towards the upstream supplier. I...

Competition authorities are under severe political pressure to intervene quickly against the digital behemoth for a variety of reasons. Various expert reports have suggested that traditional antitrust or competition law enforcement and merger control are inadequate or insufficient to deal with...

This paper contributes to the analysis of mergers in two-sided markets, notably those in which a platform provides its service for free on one side but obtains all its revenues from the other, as in the digital TV industry. Specifically, we assess a decision of the French competition authority...

Digital antitrust is at the forefront of all expert discussions and is far from becoming an area of consensus among researchers. Moreover, the prescriptions for developed countries do not fit well the situation in developing countries, and namely in BRICS: where the violator of antitrust laws is...

The majority of digital platform research has focused on consumer-centric platforms. Driven by the vast growth potential of direct consumer market access, industrial communities locked behind the conventional gatekeepers in their respective value chains have lately started to tinker with their...

This paper describes the different forces that shape the market structure of four different 'online platform ecosystems' and the competition between them. The paper focuses on the following categories of platforms, which represent a wide scope of online activities: (i) e-commerce marketplaces;...

The aim of this paper is to explain evidence of unfair practices by online platforms towards business users, particularly SME's. First, using survey data, we show that sellers operating with four different categories of platforms multi-home (marketplaces, app stores, social networks and online...

This report presents evidence on the relationship between online platforms and businesses using these platforms to reach consumers or conduct their operations. First, we review the literature on vertical relationships both from a classic approach and from a multi-sided market perspective....

In theoretical analyses on terrorism and the media, the structure of the media market has thus far been neglected. The present paper adopts a multi-sided market framework in order to explore the ways in which the markets for terrorism, advertising, and the media influence each other. Although...
