In new research, Wolfgang Kerber argues that the European Union's decision to require a third option in Meta's "consent or pay" model focuses too heavily on user consent and ignores the broader goal in the Digital Markets Act of reducing gatekeeper advantages and increasing competition.

The following is an excerpt from Seeing Like a Supply Chain by Miriam Posner, now out at Yale University Press.

As banks grow, tiered regulation places them in stricter categories to address their greater risks. In new research, Pedro M. Batista finds that transition periods between tiers might delay when some higher standards become mandatory, potentially leaving growing banks exposed while known risks remain unresolved, as happened with Silicon Valley Bank. Federal Reserve reforms should address this gap between growing risks and delayed safeguards.

Freeman, Danxia Xie, Hanzhe Zhang, and Hanzhang Zhou discuss in new research, prizewinners in economics continue to come from a narrow set of American institutions.  

For decades antitrust agencies, courts, and scholars have debated whether Section 7 of the Clayton Act permits an efficiency defense, in which merging firms can argue that enhanced efficiencies from the merger show that it does not reduce competition. However, the Supreme Court’s recent establishment of the “major questions doctrine,” which enforces or re-enforces a textualist reading of regulatory statues, undermines proponents of the efficiency defense, because the Clayton Act does not clearly and explicitly contain an efficiency defense. The “major questions doctrine” essentially acts as textualism on steroids,” writes Robert H. Lande.

In new analysis, Madhav Parikh examines how competition among banks in the United States shapes the way monetary policy reaches depositors. Tracking U.S. banks from late 2021 through mid-2026, he finds that banks in more concentrated local markets repriced their deposit interest rates less than banks in competitive markets, both as the Fed raised rates and as it cut them.

The Digital Markets Act establishes central rules and enforcement for digital platforms across the European Union, but allows decentralized private enforcement on the national level.
