Mergers in digital markets have been much discussed in recent years, following the growing concerns around the acquisition strategies of major tech platforms. In parallel to the well-known debate on killer acquisitions and notification thresholds, new questions have started to emerge about the suitability of existing theories of harm for an effective assessment of mergers in digital markets. In June 2023 the OECD held a roundtable discussing the theories of harm currently used in the analysis of digital mergers, the potential need to develop new ones that could better capture competitive harms, and the challenges that this may bring for competition authorities. KEY FINDINGS FROM THE JUNE 2023 DISCUSSION The discussion highlighted the fact that specific features of digital mergers, such as the prominent role of platform ecosystems relying on strong network effects, high quality algorithms, economies of scale and data-driven economies of scope, bring into question the ability of traditional theories of harm to reflect the real competitive harm that may result from mergers in these markets. Contributions from delegates indicated that many jurisdictions have already sought to fine-tune theories of harm to better reflect the specific characteristics of digital markets, including to account for network effects, harms to innovation and privacy, and the potential for mergers to entrench ecosystems. Some delegates indicated their intention to move further in this direction, including through the revision of merger guidelines, while others encouraged caution and a need to first identify a clear enforcement gap in unambiguous terms. Challenges were identified, including with respect to the ability of competition authorities to continue meet legal tests and standards of proof.
2024 OECD COMPETITION OPEN DAY EXPLORES THEORIES OF HARM FOR DIGITAL MERGERS The topic will again be explored again on 6 March 2024 during the 2024 OECD Competition Open Day, an event open to the public. Learn more about it and register now to attend in person or online!
