Marktübergreifendes Wachstum in der Digitalwirtschaft

What economic motives underlie the cross-market growth of digital gatekeepers and how can the resulting problems for competition be legally addressed? This work explores the core of this question. Based on the findings, proposals for competition regulation are developed, including an assessment of the rules of the Digital Markets Act and Section 19a GWB. A concrete legislative proposal for a reform of merger control is submitted. A plea is made for the introduction of a special merger control regime for competitively relevant strategic acquisitions by digital gatekeepers.
