Cost-Benefit Analysis Without the Benefits or the Analysis: How Not to Draft Merger Guidelines

Abstract

Previous iterations of the DOJ/FTC Merger Guidelines have articulated a clear, rigorous, and transparent methodology for balancing the pro-competitive benefits of mergers against their anticompetitive costs. By describing agency practice, guidelines facilitate compliance, ensure consistent and reasonable enforcement, increase public understanding and confidence, and promote international cooperation.

But the 2023 Draft Merger Guidelines do not. They go to great lengths to articulate the potential anticompetitive costs of mergers but with no way to gauge “substantiality.” Most significantly, they ignore potential benefits, which eliminates the need for balancing. In other words, the Draft Guidelines provide very little guidance about current practice which adds risk, which deters mergers, which seems to be the point. We offer specific recommendations for Horizontal, Vertical, and Tech Mergers that do a better job differentiating procompetitive mergers from anticompetitive ones.
