Labor Antitrust Analysis Should Focus on Actual Anticompetitive Agreements

Alden Abbott —  5 May 2022

Biden administration enforcers at the U.S. Justice Department (DOJ) and the Federal Trade Commission (FTC) have prioritized labor-market monopsony issues for antitrust scrutiny (see, for example, here and here). This heightened interest comes in light of claims that labor markets are highly concentrated and are rife with largely neglected competitive problems that depress workers’ income. Such concerns are reflected in a March 2022 U.S. Treasury Department report on “The State of Labor Market Competition.”

Monopsony is the “flip side” of monopoly and U.S. antitrust law clearly condemns agreements designed to undermine the “buyer side” competitive process (see, for example, this U.S. government submission to the OECD). But is a special new emphasis on labor markets warranted, given that antitrust enforcers ideally should seek to allocate their scarce resources to the most pressing (highest valued) areas of competitive concern?

A May 2022 Information Technology & Innovation (ITIF) study from ITIF Associate Director (and former FTC economist) Julie Carlson indicates that the degree of emphasis the administration’s antitrust enforcers are placing on labor issues may be misplaced. In particular, the ITIF study debunks the Treasury report’s findings of high levels of labor-market concentration and the claim that workers face a “decrease in wages [due to labor market power] at roughly 20 percent relative to the level in a fully competitive market.” Furthermore, while noting the importance of DOJ antitrust prosecutions of hard-core anticompetitive agreements among employers (wage-fixing and no-poach agreements), the ITIF report emphasizes policy reforms unrelated to antitrust as key to improving workers’ lot.

Key takeaways from the ITIF report include:

  • Labor markets are not highly concentrated. Local labor-market concentration has been declining for decades, with the most concentrated markets seeing the largest declines.
  • Labor-market power is largely due to labor-market frictions, such as worker preferences, search costs, bargaining, and occupational licensing, rather than concentration.
  • As a case study, changes in concentration in the labor market for nurses have little to no effect on wages, whereas nurses’ preferences over job location are estimated to lead to wage markdowns of 50%.
  • Firms are not profiting at the expense of workers. The decline in the labor share of national income is primarily due to rising home values, not increased labor-market concentration.
  • Policy reform should focus on reducing labor-market frictions and strengthening workers’ ability to collectively bargain. Policies targeting concentration are misguided and will be ineffective at improving outcomes for workers.

The ITIF report also throws cold water on the notion of emphasizing labor-market issues in merger reviews, which was teed up in the January 2022 joint DOJ/FTC request for information (RFI) on merger enforcement. The ITIF report explains:

Introducing the evaluation of labor market effects unnecessarily complicates merger review and needlessly ties up agency resources at a time when the agencies are facing severe resource constraints.48 As discussed previously, labor markets are not highly concentrated, nor is labor market concentration a key factor driving down wages.

A proposed merger that is reportable to the agencies under the Hart-Scott-Rodino Act and likely to have an anticompetitive effect in a relevant labor market is also likely to have an anticompetitive effect in a relevant product market. … Evaluating mergers for labor market effects is unnecessary and costly for both firms and the agencies. The current merger guidelines adequately address competition concerns in input markets, so any contemplated revision to the guidelines should not incorporate a “framework to analyze mergers that may lessen competition in labor markets.” [Citation to Request for Information on Merger Enforcement omitted.]

In sum, the administration’s recent pronouncements about highly anticompetitive labor markets that have resulted in severely underpaid workers—used as the basis to justify heightened antitrust emphasis on labor issues—appear to be based on false premises. As such, they are a species of government misinformation, which, if acted upon, threatens to misallocate scarce enforcement resources and thereby undermine efficient government antitrust enforcement. What’s more, an unnecessary overemphasis on labor-market antitrust questions could impose unwarranted investigative costs on companies and chill potentially efficient business transactions. (Think of a proposed merger that would reduce production costs and benefit consumers but result in a workforce reduction by the merged firm.)

Perhaps the administration will take heed of the ITIF report and rethink its plans to ramp up labor-market antitrust-enforcement initiatives. Promoting pro-market regulatory reforms that benefit both labor and consumers (for instance, excessive occupational-licensing restrictions) would be a welfare-superior and cheaper alternative to misbegotten antitrust actions.
