Revisions to the Merger Guidelines: Above All, Do No Harm
My sense is that there is no need to revise the DOJ/FTC Horizontal Merger Guidelines, with one exception. As Greg Werden points out, “a thorough revision would take up to three years and occupy some of the agencies’ best people for a total of more than two thousand hours.” The current guidelines lay out the ...

Fix the Supply Side
Do the Merger Guidelines need revision? No. Thanks for having me. OK. Yes–and market definition/market shares, and in particular the effective incorporation of supply-side effects, seem to me like the most pressing issues in need of attention. Judge Posner, in the first edition of his justly celebrated Antitrust Law, noted that market definition was an ... Fix the Supply Side
"Standardizing" the Horizontal Merger Guidelines
I’m confident that my esteemed colleagues, who have far more expertise about the merger guidelines than I, will offer all sorts of terrific ideas for revising the substance of the guidelines. While I would certainly advocate a few specific changes (i.e., revise the HHI thresholds to reflect actual agency practice), I’ll leave the devilish details ...

Herbert Hovenkamp on Revising the Merger Guidelines
Yes, the Merger Guidelines should be revised; in particular: a. The discussion of concentration thresholds for collusion facilitating mergers must be aligned more closely with both recent case law and actual enforcement practices; otherwise they fail to provide guidance. The current Guidelines indicate that concentrations greater than 1800 HHI and a post-merger increase exceeding 100HHI ... Herbert Hovenkamp on Revising the Merger Guidelines
Let Sleeping Dogs…
I feel no great urgency to revise the Guidelines. True enough, they’re more of an analytical thought experiment than an accurate description of how merger review takes place in the agencies, but who’s really fooled? Perhaps some business people think that the Guidelines are a computer program waiting for the introduction of the relevant data ... Let Sleeping Dogs…
Andrew Gavil on Revising the Merger Guidelines
1. Do the Merger Guidelines Need Revision? Yes. Conceptually, the current Guidelines incorporate multiple strands of intellectual and legal history with respect to merger analysis that have been layered one upon the other over time, but never effectively integrated. This now encumbers the application of the Guidelines and may be inhibiting the government’s capacity to ... Andrew Gavil on Revising the Merger Guidelines
The Guidelines Should Be Revised to Reject the PNB Structural Presumption
Yes, the Merger Guidelines should be revised. The Guidelines primary purpose is to “articulate the analytical framework the Agency applies in determining whether a merger is likely substantially to lessen competition.” While the Guidelines have been very successful in articulating a useful economic framework for analyzing mergers, their performance in terms of satisfying that goal ... The Guidelines Should Be Revised to Reject the PNB Structural Presumption
Do the Merger Guidelines Need Revision?
The merger guidelines should be revised, not only to provide clearer guidance, but because the current version makes it harder for the agencies to win cases when they do challenge a merger. The reason is that the guidelines often don’t fit actual agency practice or modern economic theory. For example, part of the reason the ... Do the Merger Guidelines Need Revision?
Dynamic Competition in Antitrust Law
The Horizontal Merger Guidelines are the intellectual cornerstone of modern antitrust law, yet they contain little discussion of innovation or dynamic competition. Although the Merger Guidelines do not constitute law merely by virtue of their promulgation by the agencies, the courts previously have accepted the revised principles that the agencies have advocated. By embracing the ... Dynamic Competition in Antitrust Law
Comments on Updating the Merger Guidelines
Of course, the Merger Guidelines need to be updated. Except for efficiencies, they haven’t been updated in 17 years. Lawyers and economists with a regular antitrust practice may not require an update in light of their knowledge of the 2006 Commentary, speeches and agency experience. But, the rest of the antitrust world does. The most ... Comments on Updating the Merger Guidelines
Robert Gertner on Revising the Guidelines
The stated purpose of the DOJ/FTC Horizontal Merger Guidelines is to “reduce the uncertainty associated with enforcement of the antitrust laws.” The Guidelines have had limited success in achieving this goal. They generally succeed in two important dimensions and fail in one. First, the Guidelines lay out a five step analysis consisting of market definition, ... Robert Gertner on Revising the Guidelines
