On 18 July 2024, the current President of the European Commission (“Commission”), Ursula von der Leyen, was reconfirmed by the European Parliament for a second 5-year term. As part of her reconfirmation, President von der Leyen delivered a speech before the European Parliament, complemented by a 30-page program, which lays down the Commission’s political program for the next five years.

A key pillar of the program – “A new plan for Europe’s sustainable prosperity and competitiveness” – has the objective of combining competitiveness and prosperity with the achievement of the European Green Deal goals.

Specifically on competition policy, according to President von der Leyen, a new approach is needed to achieve this objective. This blog post projects where competition policy is likely headed in the 2024-2029 period by commenting on the most relevant paragraphs of the program.Continue Reading The 2024-2029 Commission Political Guidelines: Where Is Competition Policy Likely Headed?

On July 19, 2023, the Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice (collectively, “the Agencies”) issued a new set of merger guidelines in draft form for public comment (the “Draft Guidelines”).  The Draft Guidelines, if adopted, will replace the Horizontal Merger Guidelines issued in 2010 and the Vertical Merger Guidelines issued in 2020 (the latter of which the FTC withdrew in September 2021).  The updates make significant changes to the guidelines, such as:

  • Lowering the thresholds for when the Agencies are likely to presume that horizontal mergers are illegal;
  • Including—for the first time—a presumption of illegality for certain vertical mergers;
  • Adding guidelines focused on serial acquisitions and acquisitions of potential competitors;
  • Introducing concepts related specifically to multi-sided “platforms”; and
  • Explicitly addressing the effects of transactions on labor markets for the first time.

On December 10th, the Antitrust Division of the U.S. Department of Justice announced its first criminal indictment targeting an alleged conspiracy to reduce employee wages. The DOJ charged the former owner of a therapist staffing company with conspiring to reduce pay rates for healthcare worker contractors, but did not charge the company itself. Specifically, the indictment alleges that, for a six-month period in 2017, the defendant and his co-conspirators exchanged non-public information on rates paid to healthcare workers; discussed and agreed to decrease rates paid to healthcare workers; implemented rate decreases in accordance with their agreement; and paid healthcare workers at collusive and noncompetitive rates. The indictment alleges that the defendant’s behavior constitutes a per se violation of the antitrust laws and seeks penalties including fines and potential imprisonment. The indictment also includes an obstruction of justice charge, stemming from allegedly false or misleading information the defendant provided the Federal Trade Commission during the agency’s investigation of the same subject matter.
