Enforcing the Digital Markets Act: institutional choices, compliance, and antitrust

This article discusses how the European Commission can achieve the goal of effectively implementing the Digital Markets Act. Based on legal and economic reasoning, we highlight the important role of the gatekeeper's compliance report, and discuss how to incentivize gatekeepers to write useful reports. In addition, we develop recommendations regarding the internal organization of the Commission, the prioritization of cases, and how to effectively use the concurrent enforcement powers of the Digital Markets Act and Article 102 of the TFEU. We illustrate the principles we develop using four different EU antitrust cases. Furthermore, we discuss coordination between the Commission and National Competition Authorities and the need to already develop an independent evaluation process for the Digital Markets Act.
