Competitive Harm From Vertical Mergers, Herbert J. Hovenkamp

All Faculty Scholarship

The antitrust enforcement Agencies' 2020 Vertical Merger Guidelines introduce a nontechnical application of bargaining theory into the assessment of competitive effects from vertical acquisitions. The economics of such bargaining is complex and can produce skepticism among judges, who might regard its mathematics as overly technical, its game theory as excessively theoretical or speculative, or its assumptions as unrealistic.

However, we have been there before. The introduction of concentration indexes, particularly the HHI, in the Merger Guidelines was initially met with skepticism but gradually they were accepted as judges became more comfortable with them. The same thing very largely happened again …

All Faculty Scholarship

The House Judiciary Antitrust Subcommittee asked me to submit suggestions concerning the adequacy of existing antitrust laws, enforcement policies, and enforcement levels insofar as they impact the state of competition in the digital marketplace.
