Taming digital gatekeepers: the 'more regulatory approach' to antitrust law

Antitrust enforcement and competition policy in the digital economy is high on the agenda of authorities and policymakers. The distinctive features of digital markets and the strategic role played by large platforms apparently require a rethinking of the antitrust regime. Several reform proposals point to the need to integrate the antitrust toolkit with ex ante measures since there is a risk that ex post enforcement would be too slow to successfully keep markets competitive and contestable. The aim of this paper is to investigate whether the invoked regulatory approach reflects the distinctive structural features of digital markets or whether it is just an enforcement short-cut.
