Introduction to the RIO Special Issue on Antitrust and the Platform Economy

The emergence of large technology platforms has raised fundamental questions about antitrust enforcement. These questions, which are the subject of this RIO special issue, are now challenging scholars and policy makers. The topics covered here include the role of economics and the consumer welfare standard in antitrust; lessons from historic antitrust cases; the role of big data in antitrust analysis; antitrust analysis of multi-sided markets; and the interplay between competition and privacy regulation.
