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.

Prizewinning research in most science-related academic fields has become less concentrated among institutions. However, as Richard B. 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.

Financial crises routinely trigger sweeping overhauls of financial regulation, but whose interests do these reforms serve? In new research, Orkun Saka, Yuemei Ji, and Clement Minaudier find that political leaders facing term limits are much more likely to respond to financial crises by introducing reforms that benefit banks over the public or long-term financial stability. This phenomenon occurs more frequently in countries where the revolving door between politics and finance is common.

Firms can now charge each shopper a different price, and regulators worry that the gains will flow from consumers to companies. But personalized pricing has two built-in limits: shoppers learn to hide how much they want things, and cheap purchases can be resold, writes Nursultan Mukhtaruly.
