My recent Essay, Has the Obama Justice Department Reinvigorated Antitrust Enforcement?, examined the three major areas of antitrust enforcement—cartels, mergers, and civil non-merger—and argued that, contrary to some popular impressions, the Obama Justice Department has not “reinvigorated” antitrust enforcement. Jonathan Baker and Carl Shapiro have published a response, which focuses solely on merger enforcement. Baker and Shapiro’s argument that the Obama Justice Department actually did reinvigorate merger enforcement is unconvincing.
