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.


Network Effects In Action, Christopher S. Yoo Nov 2020

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 …

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 Jan 2020

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 …
