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.

Network Effects In Action, Christopher S. Yoo

All Faculty Scholarship

This Chapter begins by examining and exploring the theoretical and empirical limits of the possible bases of network effects, paying particular attention to the most commonly cited framework known as Metcalfe’s Law. It continues by exploring the concept of network externalities, defined as the positive external consumption benefits that the decision to join a network creates for the other members of the network, which is more ambiguous than commonly realized. It then reviews the structural factors needed for models based on network effects to have anticompetitive effects and identifies other factors that can dissipate those effects. Finally, it identifies alternative …

Competitive Harm From Vertical Mergers, Herbert J. Hovenkamp

All Faculty Scholarship

The antitrust enforcement Agencies' 2020 Vertical Merger Guidelines introduce a nontechnical application of bargaining theory into the assessment of competitive effects from vertical acquisitions. The economics of such bargaining is complex and can produce skepticism among judges, who might regard its mathematics as overly technical, its game theory as excessively theoretical or speculative, or its assumptions as unrealistic.

However, we have been there before. The introduction of concentration indexes, particularly the HHI, in the Merger Guidelines was initially met with skepticism but gradually they were accepted as judges became more comfortable with them. The same thing very largely happened again …

The Post-Chicago Antitrust Revolution: A Retrospective, Christopher S. Yoo

All Faculty Scholarship

A symposium examining the contributions of the post-Chicago School provides an appropriate opportunity to offer some thoughts on both the past and the future of antitrust. This afterword reviews the excellent papers with an eye toward appreciating the contributions and limitations of both the Chicago School, in terms of promoting the consumer welfare standard and embracing price theory as the preferred mode of economic analysis, and the post-Chicago School, with its emphasis on game theory and firm-level strategic conduct. It then explores two emerging trends, specifically neo-Brandeisian advocacy for abandoning consumer welfare as the sole goal of antitrust and the …

Prophylactic Merger Policy, Herbert J. Hovenkamp

All Faculty Scholarship

An important purpose of the antitrust merger law is to arrest certain anticompetitive practices or outcomes in their “incipiency.” Many Clayton Act decisions involving both mergers and other practices had recognized the idea as early as the 1920s. In Brown Shoe the Supreme Court doubled down on the idea, attributing to Congress a concern about a “rising tide of economic concentration” that must be halted “at its outset and before it gathered momentum.” The Supreme Court did not explain why an incipiency test was needed to address this particular problem. Once structural thresholds for identifying problematic mergers are identified there …

Framing A Purpose For Corporate Law, William W. Bratton

All Faculty Scholarship

This article seeks to frame a short statement of purpose for corporate law on which all reasonable observers can agree. The statement, in order to succeed at its intended purpose, must satisfy two strict conditions: first, it must have enough content to be meaningful; second, it must be completely uncontroversial, both descriptively and normatively. The exercise, thus described, involves avoiding the issues that occupy center stage in discussions about corporate law while at the same time highlighting the discussants’ generally held presuppositions. Three closely interconnected issues arise. First, whether the statement of the purpose of corporate law should speak in …

Distributive Justice And Consumer Welfare In Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

The dominant view of antitrust policy in the United States is that it is intended to promote some version of economic welfare. More specifically, 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.

The distribution concern that has dominated debates over United States antitrust policy over the last several decades is whether antitrust should adopt a “consumer welfare” principle rather than a more general neoclassical “total welfare” principle. In The Antitrust Paradox Robert …

Antitrust And The Costs Of Movement, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust is rightfully concerned about the structure of markets as well as the bargaining that occurs in them. As a result, the absolute cost of redeploying resources can be just as important as the transaction costs of arranging for their movement. This paper examines several broad themes in antitrust, considering the role of various assumptions about the costs of getting resources moved toward superior positions and the ability of the antitrust system to facilitate this movement. Part II very briefly examines structuralism as a theory underlying antitrust enforcement, particularly its assumptions about the difficulty and costs of moving resources. Harvard …
