Details

Big Tech Acquisitions and Merger Control is a book elucidating the phenomenon which is now often referred to as ‘killer acquisitions’ and which raises problems with regard to both the jurisdictional and the substantive aspects of merger control. Albeit legal analysis of (merger-related) firm dominance in ‘Big Tech’ has emphasised the so-called GAFAM – Google, Amazon, Facebook, Apple, and Microsoft – this important book stresses the necessity for a much broader view. Several large tech platforms continue to seek dominance in and across various market segments by acquiring small start-up companies with high competitive potential but yet little or no turnover, thereby running the risk of escaping antitrust scrutiny.

What’s in this book:

Drawing on legislative initiatives and enforcement practice, especially in the European Union and the United Kingdom, and through an in-depth analysis of the most prominent decisions concerning Big Tech acquisitions, the author spells out the nature of the following relevant legal issues and strategies:

the economic principles of platform competition and the particularities of digital ‘ecosystems’, including their implications for merger control
an extensive comparison of different jurisdictional rules and notification requirements beyond standard turnover thresholds
how Big Tech acquisitions can be subjected to scrutiny in the European Union via referrals under Article 22 of the European Union Merger Regulation (EUMR), potentially in combination with national ‘call-in’ tools and/or Article 14 of the Digital Markets Act (DMA), and how the latter compares to the reporting requirement under the Digital Markets, Competition and Consumers (DMCC) Act in the United Kingdom
market definition and market power assessments, including but not limited to social media and advertising markets
how both traditional and novel theories of harm can be applied in the context of digital platforms and ecosystems
application of theories of harm relating to ‘killer acquisitions’ and ‘reverse killer acquisitions’
the development of an ‘ecosystem’ theory of harm, and
artificial intelligence as the new frontier

Policy proposals and the academic legal literature are accounted for, with due regard to economic considerations as well.

How this will help you:

As competition authorities and legislators around the globe struggle to find a befitting response to the expansion and consolidation of dominance in various digital markets, it becomes imperative to contemplate alternatives to the current turnover-based notification thresholds and to rethink the substantive assessment of Big Tech acquisitions. This book, with its thorough guidance on the characteristics, challenges, and treatment of digital platforms and ecosystems in the context of merger control – and its clear exposition of applicable theories of harm – will significantly aid practitioners, competition authorities, and policymakers in effectively navigating the challenging tasks of establishing jurisdiction, defining relevant markets, and assessing market power and competitive harm.
