Navigating the Platform Age : the ‘More Regulatory Approach’ to Antitrust Law in the EU and the U.S

The economic features of digital markets and the strategic role played by large platforms represent the premises of a significant shift in the approach to the interface between antitrust and regulation, whereas traditionally the former has been seen as preferable to the latter.
