Antitrust and Competition

A key distinction in economic viewpoints that goes oft-unnoticed is between pro-business and pro-market. A good bellwether to where someone stands on the pro-business/market continuum is his/her stance on antitrust policy: pro-business usually favors incumbents, while pro-market calls for aggressive antitrust enforcement to facilitate competition.
“I would not dispute that even a monopoly-ridden market would be preferable to any economic system trying to operate without any kind of a market. But given the prevalence or the danger of substantial intrusion of monopoly into the market, the logic of the laissez faire defense of the market against state-intervention collapses and there is called for instead, by its very logic, state-suppression or state-regulation of monopoly practices, which one may wish to call, as Henry Simons called it, an instance of “positive laissez faire” or, as I prefer, as an instance of deliberate departure from laissez faire.” Jacob Viner – The Intellectual History of Laissez Faire (1960)

Meta’s Winning Market Definition in Its Monopoly Case Relied on a Flawed Empirical Assumption

Clement Mulock
Meta prevailed in its monopoly case against the Federal Trade Commission by showing that the FTC’s market definition of personal social media was too narrow. However, Meta’s argument—and Judge James Boasberg’s ruling—rested on a flawed empirical assumption that confuses how users divert their time to other activities when no longer able to use a Meta platform with true product substitution.

Everyone Wants Competition. Few Ask What Kind

Shai Agmon
In a new volume chapter, Shai Agmon and Samuel Bagg argue that academic and policy references to “competition” often fail to distinguish between competition’s many forms. Their disaggregation of competition into two complementary processes—parallel and friction competition—helps to clarify the neo-Brandeisian approach to competition policy and its advantages over the traditional consumer welfare approach.

AI Transforms Search in a Way That Could Make Google’s Default Advantage Stronger

Cristian Santesteban
Judge Amit Mehta’s remedies for Google’s search monopoly stopped short of banning payments for default search placement, reflecting the hope that generative AI will erode the power of traditional search. Cristian Santesteban argues the opposite: in the AI era of search, defaults may matter more by steering critical data and learning signals from AI-powered search sessions to the most dominant product. This mechanism can potentially compound Google’s advantage.

Repealing P2B-Regulation as Part of Digital Omnibus Allows the EU To AI-Proof the DMA

Jan-Frederick Göhsl
The EU’s proposed Digital Omnibus to simplify digital regulation suggests repealing the 2019 Platform-to-Business Regulation. This poses a problem for the Digital Markets Act, which relies on the P2B-Regulation for how to define core platform services like search engines. Moving forward with the repeal will require legislators to renegotiate first the DMA, which is necessary anyways to adapt the law to the age of artificial intelligence, writes Jan-Frederick Göhsl.

The Jedi Blue Network Bidding Agreement Is Monopoly Maintenance

Joshua Gray
Previous plaintiffs have argued unsuccessfully that Google’s Jedi Blue agreement with Facebook is anticompetitive and illegal. The agreement grants Facebook preferential access to Google’s dominant digital advertisement system in exchange for not building competing technologies. The plaintiffs’ challenges to Jedi Blue would have been on stronger ground had they argued that Jedi Blue is compelling evidence of illegal monopoly maintenance, as occurred in Microsoft, writes Joshua B. Gray.

The Nexstar-Tegna Merger Will Raise Your Cable Bill, and Then Some

Diana L. Moss
The proposed merger of local broadcast television station owners Nexstar and Tegna will create a behemoth that threatens to raise consumer prices for multi-video programming subscriptions, increase advertising rates for local businesses, and reduce viewers’ exposure to diverse viewpoints. The government can and should block the merger but politics threatens to usurp law and economics, writes Diana L. Moss.
