The Looming Crisis In Antitrust Economics, Herbert J. Hovenkamp Jan 2021

The Looming Crisis In Antitrust Economics, Herbert J. Hovenkamp

All Faculty Scholarship

As in so many areas of law and politics in the United States, antitrust’s center is at bay. It is besieged by a right wing that wants to limit antitrust even more than it has been limited over the last quarter century. On the left, it faces revisionists who propose significantly greater enforcement.

One thing the two extremes share, however, is denigration of the role of economics in antitrust analysis. On the right, the Supreme Court’s two most recent antitrust decisions at this writing reveal that economic analysis no longer occupies the central role that it once had. On the …


Is The Digital Economy Too Concentrated?, Jonathan Klick Nov 2020

Is The Digital Economy Too Concentrated?, Jonathan Klick

All Faculty Scholarship

Concentration in the digital economy in the United States has sparked loud criticism and spurred calls for wide-ranging reforms. These reforms include everything from increased enforcement of existing antitrust laws, such as challenging more mergers and breaking up firms, to an abandonment of the consumer welfare standard. Critics cite corruption and more systemic public choice problems, while others invoke the populist origins of antitrust to slay the digital Goliaths. On the other side, there is skepticism regarding these arguments. This chapter continues much of that skepticism.


House Judiciary Inquiry Into Competition In Digital Markets: Statement, Herbert J. Hovenkamp Apr 2020

House Judiciary Inquiry Into Competition In Digital Markets: Statement, Herbert J. Hovenkamp

All Faculty Scholarship

This is a response to a query from the Judiciary Committee of the U.S. House of Representatives, requesting my views about the adequacy of existing antitrust policy in digital markets.

The statutory text of the United States antitrust laws is very broad, condemning all anticompetitive restraints on trade, monopolization, and mergers and interbrand contractual exclusion whose effect “may be substantially to lessen competition or tend to create a monopoly.” Federal judicial interpretation is much narrower, however, for several reasons. One is the residue of a reaction against excessive antitrust enforcement in the 1970s and earlier. However, since that time antitrust …


Platforms And The Rule Of Reason: The American Express Case, Herbert J. Hovenkamp Jan 2019

Platforms And The Rule Of Reason: The American Express Case, Herbert J. Hovenkamp

All Faculty Scholarship

In Ohio v. American Express Co., the Supreme Court applied antitrust’s rule of reason to a two-sided platform. The challenge was to an “anti-steering” rule, a vertical restraint preventing merchants from shifting customers who offered an AmEx card from to a less costly alternative such as Visa or Mastercard.

A two-sided platform is a business that depends on relationships between two different, noncompeting groups of transaction partners. For example, a printed periodical such as a newspaper earns revenue by selling both advertising and subscriptions to the paper itself. Success depends on a platform’s ability to maintain the appropriate balance …


Hipster Antitrust: New Bottles, Same Old W(H)Ine?, Christopher S. Yoo Apr 2018

Hipster Antitrust: New Bottles, Same Old W(H)Ine?, Christopher S. Yoo

All Faculty Scholarship

Although the debate over hipster antitrust is often portrayed as something new, experienced observers recognize it as a replay of an old argument that was resolved by the global consensus that antitrust should focus on consumer welfare rather than on the size of firms, the levels of industry concentration, and other considerations. Moreover, the history of the Federal Trade Commission’s Section 5 authority to prevent unfair methods of competition stands as a reminder of the dangers of allowing enforcement policy to be guided by vague and uncertain standards.


Antitrust And Information Technologies, Herbert J. Hovenkamp Mar 2016

Antitrust And Information Technologies, Herbert J. Hovenkamp

All Faculty Scholarship

Technological change strongly affects the use of information to facilitate anticompetitive practices. The effects result mainly from digitization and the many products and processes that it enables. These technologies of information also account for a significant portion of the difficulties that antitrust law encounters when its addresses intellectual property rights. In addition, changes in the technologies of information affect the structures of certain products, in the process either increasing or decreasing the potential for competitive harm.

For example, digital technology affects the way firms exercise market power, but it also imposes serious measurement difficulties. The digital revolution has occurred in …


Implementing Antitrust's Welfare Goals, Herbert J. Hovenkamp Jan 2014

Implementing Antitrust's Welfare Goals, Herbert J. Hovenkamp

All Faculty Scholarship

United States antitrust policy is said to promote some version of economic welfare. Antitrust promotes allocative efficiency by ensuring that markets are as competitive as they can practicably be, and that firms do not face unreasonable roadblocks to attaining productive efficiency, which refers to both cost minimization and innovation. One important welfare debate is whether antitrust should adopt a “consumer welfare” principle rather than a more general “total welfare” principle.

The simple version of the consumer welfare test is not a balancing test. If consumers are harmed by reduced output or higher prices resulting from the exercise of market power, …


Harm To Competition Under The 2010 Horizontal Merger Guidelines, Herbert J. Hovenkamp Jan 2014

Harm To Competition Under The 2010 Horizontal Merger Guidelines, Herbert J. Hovenkamp

All Faculty Scholarship

In August, 2010, the Antitrust Division and the Federal Trade Commission issued new Guidelines for assessing the competitive effects of horizontal mergers under the antitrust laws. These Guidelines were long awaited not merely because of the lengthy interval between them and previous Guidelines but also because enforcement policy had drifted far from the standards articulated in the previous Guidelines. The 2010 Guidelines are distinctive mainly for two things. One is briefer and less detailed treatment of market delineation. The other is an expanded set of theories of harm that justify preventing mergers or reversing mergers that have already occurred.

The …


Is There A Role For Common Carriage In An Internet-Based World?, Christopher S. Yoo Jan 2013

Is There A Role For Common Carriage In An Internet-Based World?, Christopher S. Yoo

All Faculty Scholarship

During the course of the network neutrality debate, advocates have proposed extending common carriage regulation to broadband Internet access services. Others have endorsed extending common carriage to a wide range of other Internet-based services, including search engines, cloud computing, Apple devices, online maps, and social networks. All too often, however, those who focus exclusively on the Internet era pay too little attention to the lessons of the legacy of regulated industries, which has long struggled to develop a coherent rationale for determining which industries should be subject to common carriage. Of the four rationales for determining the scope of common …


When Antitrust Met Facebook, Christopher S. Yoo Jul 2012

When Antitrust Met Facebook, Christopher S. Yoo

All Faculty Scholarship

Social networks are among the hottest phenomena on the Internet. Facebook eclipsed Google as the most visited website in both 2010 and 2011. Moreover, according to Nielsen estimates, as of the end of 2011 the average American spent nearly seven hours per month on Facebook, which is more time than they spent on Google, Yahoo!, YouTube, Microsoft, and Wikipedia combined. LinkedIn’s May 19, 2011 initial public offering (“IPO”) surpassed expectations, placing the value of the company at nearly $9 billion, and approximately a year later, its stock price had risen another 20 percent. Facebook followed suit a year later with …
