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 inflation itself is unlikely to cause the greatest economic harm during inflationary periods. Instead, a more likely source of devastation will be policymakers’ response to inflation. Their main anti-inflation tools, most notably increasing interest rates, increase unemployment and the risk of recessions. This Article argues that there is a better approach. Rather than defaulting to interest rate hikes that harm markets, policy makers should prioritize laws that lower prices while improving markets. For decades, businesses have raised prices by manipulating consumers, exercising monopoly power, and lobbying for laws that block competition. Automated …

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 …

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 …

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 …
