Wettbewerb auf ad tech-Märkten

Online advertising is one of the main sources for funding the digital economy. The book examines the competitive conditions in ad tech markets. In particular, self-preferencing practices by the leading company Google are analysed with regard to an abuse of market power. For this purpose, the systematics of antitrust law based on the decision-making practice of the competition authorities and the draft guidelines on abusive exclusionary conduct as well as new instruments of digital legislation (DMA, DSA, § 19a German Act against restraints of competition (GWB)) are assessed. The research question is of relevance for the functioning of digital markets in general and thus concerns wider societal aspects.
