antitrust uses and misuses (in the age of Big Data)

antitrust uses and misuses (in the age of Big Data)

Talk I gave at the conference "Designing antitrust for the digital era" (Brasília, Brazil). TL;DR: antitrust agencies shouldn't go around imposing fines and breaking up companies just because "network effects" or "data as an essential facility". Public policy must be evidence-based. And the evidence suggests that network effects and access to personal data are not preventing competition.
