Zingales & Renzetti on Digital Platform Ecosystems and Conglomerate Mergers: A Review of the Brazilian Experience

Nicolo Zingales (Getulio Vargas Foundation (FGV); Tilburg Law and Economics Center (TILEC); Stanford University – Stanford Law School Center for Internet and Society) and Bruno Renzetti (Yale University, Law School; University of Sao Paulo (USP), Faculty of Law (FD)) have posted “Digital Platform Ecosystems and Conglomerate Mergers: A Review of the Brazilian Experience” (World Competition 45 (4) (2022)) on SSRN. Here is the abstract:

This paper highlights some of the key challenges for the Brazilian merger control regime in dealing with mergers involving digital platform ecosystems (DPEs). After a quick introduction to DPEs, we illustrate how conglomerate effects that are raised by such mergers remain largely unaddressed in the current landscape for merger control in Brazil. The paper is divided in four sections. First, we introduce the reader to the framework for merger control in Brazil. Second, we identify the possible theories of harm related to conglomerate mergers, and elaborate on the way in which their application may be affected by the context of DPEs. Third, we conduct a review of previous mergers involving DPEs in Brazil, aiming to identify the theories of harm employed (and those that could have been explored) in each case. Fourth and finally, we summarize and results and suggest adaptations to the current regime, advancing proposals for a more consistent and predictable analysis.
