Joint Submission of Antitrust Economists, Legal Scholars, and Practitioners to the House Judiciary Committee on the State of Antitrust Law and Implications for Protecting Competition in Digital Markets

Written Testimonies & Filings Pursuant to the House Judiciary Committee’s request for information to aid its inquiry concerning the state of existing antitrust laws, Antitrust Economists, Legal Scholars, and Practitioners offer the following joint submission.

Pursuant to the Committee’s request for information to aid its inquiry concerning the state of existing antitrust laws, we offer the following joint submission: 

We are economists, legal scholars, and practitioners—focused on antitrust law, economics, and policy—who believe in maintaining healthy markets and well-functioning antitrust institutions. We value the important role of antitrust as the “Magna Carta of free enterprise,” which sets the rules that govern how firms compete against one another in our modern economy. Many of us have served in antitrust enforcement agencies. Each of us believes it is vital that the antitrust laws promote competitive markets, innovation, and productivity by deterring anticompetitive conduct throughout our economy, including in digital markets. 

We write because the modern antitrust debate has become characterized by sustained attacks on the integrity of antitrust institutions and by unsubstantiated dismissals of debate. This atmosphere has led to a variety of proposals for radical changes to the antitrust laws and their enforcement that we believe are unsupported by the evidence, counterproductive to promoting competition and consumer welfare, and offered with an unwarranted degree of certainty. 

Vigorous debate and disagreement have long been a hallmark of antitrust scholarship and policy. Competition policy has been formed through an iterative process echoed in the courts’evolving doctrine over more than a century. Today, however, efforts to sidestep the discussion, or to declare it over, and to force hasty and far-reaching changes have come to the fore. These proposals are numerous and include: (1) abandoning the consumer welfare standard; (2) overturning unanimous and supermajority judicial precedents, which are foundational to modern antitrust law; (3) imposing obsolete and arbitrary market share tests to determine the legality of mergers; (4) shifting the burden of proof from plaintiffs to defendants to render large swaths of business behavior presumptively unlawful; (5) creating another federal regulator to oversee competition in digital markets; (6) breaking up major tech companies or their products without evidence of antitrust harm or that the remedy would make consumers better off; and (7) imposing a general prohibition on all mergers either involving specific firms or during the current health crisis.

Such proposals would abandon the legal and political traditions that helped transform antitrust from an unprincipled and incoherent body of law, marred by internal contradictions, into a workable system that contributes positively to American competitiveness and consumer welfare. It should be noted that we use the term “consumer welfare” throughout this letter, consistent with modern parlance about competition policy, to include the benefits of competition to the welfare of workers and other input suppliers, as well as consumers. Thus, the consumer welfare standard is not a narrowly circumscribed objective, but rather a prescription for the general social wellbeing generated by the competitive process. By contrast, many of the current proposals would (1) undermine the rule of law; (2) undo the healthy evolution of antitrust law in the courts over time; (3) require antitrust agencies to micromanage the economy by picking winners and losers; (4) abandon a focus on consumer welfare in favor of vague and politically-oriented goals; and (5) undermine successful American businesses and their competitiveness in the global economy at the worst-imaginable time. 

The assertions about the state of antitrust law and policy that purportedly justify these radical changes are not supported by the evidence. A more accurate reading of the evidence supports the following view of the American economy and the role of antitrust law:

  1. The American economy—including the digital sector—is competitive, innovative, and serves consumers well. Debate about whether the antitrust laws should be fundamentally re-written originated from a concern that markets have recently become more concentrated and that competition had decreased as a result. The popular narrative, that increases in concentration have caused harm to competition throughout the economy, does not withstand close scrutiny. In reality, most markets in the American economy—including digital markets—are competitive, and thriving, and create huge benefits for consumers.
  2. Structural changes in the economy have resulted from increased competition. The economic data show that intense competition, winner-take-all rivalry, and the adoption of new successful technologies in relevant antitrust markets were major economic forces that led to structural changes (i.e., increased national-level concentration) in the economy. The existence of these structural changes does not itself support changes in the law.
  3. Lax antitrust enforcement has not allowed systematic increases in market power. There is little evidence to support the view that anemic antitrust enforcement has led to a systematic rise in market power in the American economy. The evidence is especially weak as it relates to digital markets.
  4. Existing antitrust law is adequate for protecting competition in the modern economy. Antitrust law has developed incrementally through the common law approach. A strength of antitrust law is that it can incorporate learning about new business practices and economics to protect competition in an evolving economy. The existing antitrust laws and enforcement framework, when correctly applied, are more than adequate to deter anticompetitive conduct today, including in new and growing digital markets.
  5. History teaches that discarding the modern approach to antitrust would harm consumers. Many of the radical reforms being proposed today seek to return antitrust to what it was in the 1960s. But antitrust during that time was based primarily on per se rules that prohibited economic analysis and fact-based defenses. This created a body of law, fundamentally marred by internal contradiction, that frequently protected individual competitors over consumers and did not focus on the central goal of protecting competition. Congress has considered and rejected radical proposals to overhaul antitrust in the past and should do so again.
  6. Common sense reforms should be pursued to improve antitrust enforcement. A positive agenda for antitrust reform would pursue common-sense initiatives that build upon prior learning while incorporating advances in industrial organization economics, empirical research, and analytical techniques. These proposals should focus antitrust enforcement on areas that will have the biggest return for consumers and input suppliers, support balanced retrospectives of agency decisions to identify gaps in enforcement, and address any institutional impediments to effective enforcement.

We believe open discussion of existing evidence is necessary to advance contemporary debates about the performance of antitrust institutions in the digital economy. We welcome that discussion. We discuss below various dimensions of antitrust law, economics, and institutions that have been the targets of radical reform proposals. The signatories to this letter hold a steadfast belief that antitrust institutions, including the courts, are up to the task of protecting competition, and that the federal antitrust laws as written are effective in accomplishing that goal. While many signatories have offered diverse proposals to improve the functioning of those institutions—a few of which we share in this letter—we hold the common view that the proposed radical reforms would make consumers worse off in the short run and over the long haul by chilling efficient behavior and stymieing innovation.

by Michael Baye, Bert Elwert Professor of Business at the Kelley School of Business, Indiana University, and former Director of the Bureau of Economics, FTC

Imagine a world where competition and consumer protection authorities base their final decisions on scientific evidence of potential harm. Imagine a world where well-intentioned policymakers do not use “possibility theorems” to rationalize decisions that are, in reality, based on idiosyncratic biases or beliefs. Imagine a world where “harm” is measured using a scientific yardstick that accounts for the economic benefits and costs of attempting to remedy potentially harmful business practices.

Many economists—conservatives and liberals alike—have the luxury of pondering this world in the safe confines of ivory towers; they publish in journals read by a like-minded audience that also relies on the scientific method.

Congratulations and thanks, Josh, for superbly articulating these messages in the more relevant—but more hostile—world outside of the ivory tower.

To those of you who might disagree with a few (or all) of Josh’s decisions, I challenge you to examine honestly whether your views on a particular matter are based on objective (scientific) evidence, or on your personal, subjective beliefs. Evidence-based policymaking can be discomforting: It sometimes induces those with philosophical biases in favor of intervention to make laissez-faire decisions, and it sometimes induces people with a bias for non-intervention to make decisions to intervene.

Is Antitrust Too Complicated for Generalist Judges? The Impact of Economic Complexity & Judicial Training on Appeals

Scholarship Abstract The recent increase in the demand for expert economic analysis in antitrust litigation has improved the welfare of economists; however, the law and economics . . .


The recent increase in the demand for expert economic analysis in antitrust litigation has improved the welfare of economists; however, the law and economics literature is silent on the effects of economic complexity or judges’ economic training on judicial decision-making. We use a unique data set on antitrust litigation in federal district and administrative courts during 1996-2006 to examine whether economic complexity impacts antitrust decisions, and provide a novel test of the hypothesis that antitrust analysis has become too complex for generalist judges. We also examine the impact of basic economic training by judges. We find that decisions involving the evaluation of complex economic evidence are significantly more likely to be appealed, and decisions of judges trained in basic economics are significantly less likely to be appealed than are decisions by their untrained counterparts. Our analysis supports the hypothesis that some antitrust cases are too complicated for generalist judges.

We are a group of economists (listed at the end of this letter) with extensive experience working on antitrust issues, including horizontal mergers. We applaud the Federal Trade Commission and the Department of Justice for inviting comments from the public on the proposed Horizontal Merger Guidelines (HMGs). The proposed HMGs represent a substantial advance over the existing guidelines by better explaining the methodologies actually employed at the Department of Justice and Federal Trade Commission in their evaluations of mergers. We are writing to comment on one specific aspect of the proposed HMGs: the use of price/cost margins in merger analysis.
