Getting Merger Guidelines Right, Keith N. Hylton

Faculty Scholarship

This paper is on the new Merger Guidelines. It makes several arguments. First, that the Guidelines should be understood as existing in a political equilibrium. Second, that the new structural presumption of the Merger Guidelines (HHI = 1,800) is too strict, and that an economically reasonable revision in the structural presumption would have increased rather than decreased the threshold. Whereas the new Guidelines lowers the threshold to HHI 1,800 from HHI 2,500, an economically reasonable revision would have increased the threshold to HHI 3,200. I justify this argument using a bare-bones model of Cournot competition. Third, it seems unlikely, …

Inflation, Market Failures, And Algorithms, Rory Van Loo

Faculty Scholarship

Inflation is a problem of tremendous scale. But the leading response to inflation-raising interest rates-also poses economic risks. Raising interest rates rapidly may increase unemployment and heighten the chance of recession. This Article argues that there is a better way to think about antiinflation policy. Rather than defaulting to interest rate hikes that harm markets, policymakers should prioritize laws that lower prices while improving markets. Most importantly, there is evidence that businesses have raised prices by colluding with one another, exploiting consumers' behavioral and informational limits, and lobbying for protectionist laws that block competition. Artificial intelligence pricing algorithms and dark …

On The Misuse Of Regressions Of Price On The Hhi In Merger Review, Jonathan Baker

Articles in Law Reviews & Other Academic Journals

The article explains why regressions of price on HHI should not be used in merger review. Both price and HHI are equilibrium outcomes determined by demand, supply, and the factors that drive them. Thus, a regression of price on the HHI does not recover a causal effect that could inform the likely competitive effects of a merger. Nonetheless, economic theory is consistent with the legal presumption that a merger is likely to have adverse competitive effects if it occurs in a concentrated market and makes that market more concentrated.

The Separation Of Platforms And Commerce, Lina M. Khan

Faculty Scholarship

A handful of digital platforms mediate a growing share of online commerce and communications. By structuring access to markets, these firms function as gatekeepers for billions of dollars in economic activity. One feature dominant digital platforms share is that they have inte­grated across business lines such that they both operate a platform and market their own goods and services on it. This structure places domi­nant platforms in direct competition with some of the businesses that de­pend on them, creating a conflict of interest that platforms can exploit to further entrench their dominance, thwart competition, and stifle innovation.

This Article argues …

Horizontal Shareholding And Antitrust Policy, Fiona M. Scott Morton, Herbert J. Hovenkamp

All Faculty Scholarship

“Horizontal shareholding” occurs when one or more equity funds own shares of competitors operating in a concentrated product market. For example, the four largest mutual fund companies might be large shareholders of all the major United States air carriers. A growing body of empirical literature concludes that under these conditions market output in the product market is lower and prices higher than they would otherwise be.

Here we consider how the antitrust laws might be applied to this practice, identifying the issues that courts are likely to encounter and attempting to anticipate litigation problems. We assume that neither the mutual …

Modifying Merger Consent Decrees To Improve Merger Enforcement Policy, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

This article analyzes my short proposal for reviewing and modifying merger consent decrees to permit additional relief if the provisions of the initial consent merger are found to fail to preserve or restore competition in a reasonable period of time after the merger was consummated. My proposal also would involve more frequent reviews of consummated mergers that have been cleared without challenge, particularly those that were close calls. While “Don't Look Back” might be the best anthem for artists, economic decision theory would not support that approach to merger policy.

Second-Generation Monopolization: Parallel Exclusion In Derivatives Markets, Felix B. Chang

Faculty Articles and Other Publications

The reluctance of antitrust to condemn parallel exclusion permits oligopolies to be entrenched. This is because parallel exclusion—multiple-firm conduct that inhibits market entrants—cannot satisfy the current strictures of monopolization, which is understood to prohibit single-firm conduct. Yet this is an outdated way of conceptualizing monopolization. An expansion of monopolization—to cover parallel, non-collusive acts by an oligopoly—is due.

To push the law toward recognizing parallel exclusion, this Article examines concentration in the markets for financial derivatives, which are perennially dominated by the same big banks. Even after losses under first-generation antitrust claims, the dominant derivatives dealers have found ways to retain …

Progressive Legal Thought, Herbert J. Hovenkamp

All Faculty Scholarship

A widely accepted model of American legal history is that "classical" legal thought, which dominated much of the nineteenth century, was displaced by "progressive" legal thought, which survived through the New Deal and in some form to this day. Within its domain, this was a revolution nearly on a par with Copernicus or Newton. This paradigm has been adopted by both progressive liberals who defend this revolution and by classical liberals who lament it.

Classical legal thought is generally identified with efforts to systematize legal rules along lines that had become familiar in the natural sciences. This methodology involved not …

Too Libor, Too Late: Time To Move To A Market Rate, Michael S. Barr

Articles

Barclays has been fined, the British have issued their report, and now the market is anxious for everything to go on as usual with the London Interbank Offer Rate (“LIBOR”). I think that would be a serious mistake. The U.S. and British investigations into rate-fixing by Barclays revealed a widespread culture of pervasive, deceitful conduct in the setting of the most important private sector benchmark for over $300 trillion in derivative contracts and $10 trillion in adjustable-rate loans. It is highly unlikely that Barclays was the only major bank engaging in this conduct, and public investigations and private lawsuits against …

Efficiencies In Merger Analysis: Alchemy In The Age Of Empiricism?, Thomas L. Greaney

All Faculty Scholarship

One is hard-pressed to find in law an undertaking more fraught with uncertainty than the application of the efficiencies defense in merger analysis. Generalist fact finders (judges) and politically-attuned government officials (prosecutors and regulators) are charged with two Herculean tasks: (1) predicting the outcome of organic changes in business enterprises and (2) comparing the magnitude of those changes to the equally uncertain amount of harm to future competition that the transaction will cause. Given the enormous, perhaps intractable, uncertainty of this inquiry, it is therefore paradoxical that many of the strongest advocates for strengthening the role of efficiencies analysis in …

Taking Certification Seriously – Why There Is No Such Thing As An Adequate Representative In A Securities Fraud Class Action, Richard A. Booth

Working Paper Series

Securities fraud class actions (SFCAs) arising under Rule 10b-5 are well established as a feature of the legal landscape, but they are a vestige of a largely outdated view of investor behavior and preferences. In the 1960s, most investors were undiversified stock pickers. Today, most investors hold stock through well diversified institutions. As a result, most investors are net losers from SFCAs. Moreover, it is arguable that it is irrational for most investors not to be diversified. A passive investor who fails to diversify assumes unnecessary risk for the same expected return that diversified investors enjoy. Given that federal securities …

Thirty Years Of Solicitude: Antitrust Law And Physician Cartels, Thomas L. Greaney

All Faculty Scholarship

Over the last thirty years the Federal Trade Commission and the Department of Justice have challenged dozens of physician cartels, networks, and other arrangements that they alleged constituted price fixing or other restraints of trade under the antitrust laws. In addition, the antitrust agencies have issued numerous advisory opinions, published detailed statements of enforcement policy, and made dozens of public statements on the issue of physician collaboration. The puzzle explored in this essay is why the government's deployment of unparalleled enforcement resources has not curtailed physician attempts to engage in collective bargaining and other attempts to restrain price competition. It …

Mission, Margin, And Trust In The Nonprofit Health Care Enterprise, Thomas L. Greaney, Kathleen Boozang

All Faculty Scholarship

The law governing charitable corporations remains neglected and thoroughly muddled. Still unsettled are central issues regarding the accountability of directors and management, legal standards governing organic changes by nonprofit institutions, and mechanisms to ensure fidelity to the organization's charitable mission. For nonprofit corporations in the health care sector, which represent a large proportion of all health services supplied nationwide, particularly charity care, these shortcomings have had serious repercussions. The central issue addressed in this Article is how fidelity to the mission of the charitable health care corporation should be monitored. It advances the normative perspective that the law should maximize …

Night Landings On An Aircraft Carrier: Hospital Mergers And Antitrust Law, Thomas L. Greaney

All Faculty Scholarship

Abstract: Analysis of the competitive effects of hospital mergers requires antitrust tribunals to make exceedingly fine-tuned appraisals of complex economic relationships. The law requires fact finding in a number of complex areas, e.g., defining product and geographic markets, predicting the possibility of that firms will engage in coordinated behavior; and assessing efficiencies flowing from the merger. Further complicating the process is the fact that these decisions require judgments regarding what the future may hold in an industry undergoing revolutionary change. Like pilots landing at night aboard an aircraft carrier, courts are aiming for a target that is small, shifting and …

Price Effects Of Horizontal Mergers, Alan A. Fisher Ph.D., Frederick I. Johnson Ph.D., Robert H. Lande

All Faculty Scholarship

When should the government challenge a merger that might increase market power but also generate efficiency gains? The dominant belief has been that the government and courts should evaluate these mergers solely in terms of economic efficiency. Congress, however, wanted the courts to stop any merger significantly likely to raise prices. Substantially likely efficiency gains should therefore affect the legality of mergers to the extent that they are likely to prevent price increases. This standard is more strict than the economic efficiency criterion, because the latter would permit mergers substantially likely to lead to higher prices, if sufficient efficiency gains …

Quality Of Care And Market Failure Defenses In Antitrust Health Care Litigation, Thomas L. Greaney

All Faculty Scholarship

This article considers quality-based justifications for antitrust challenges to collaboration among health care professionals. It first examines doctrinal developments resisting such justifications and, with a skeptical eye, analyzes attempts to interject quality of care and worthy motive defenses into antitrust appraisals of horizontal restraints of trade. Next the article assesses the economic basis and the risks and benefits of a market failure defense that would allow some quality-enhancing restraints of trade to escape antitrust challenge. Its principle recommendation is that courts recognize a narrow, market failure defense subject to several limiting principles to cabin its reach. The article concludes by …
