We show that bank shocks to firms propagate along the production network with stronger upstream than downstream effects. Our identification relies on (i) administrative datasets from Spain covering supplier-customer transactions and bank loans, (ii) bank ...

Social Preferences over Ordinal Outcomes

By Sandro Ambuehl and B. Douglas Bernheim

We study social preferences in settings where someone who chooses on behalf of others knows how those individuals rank the available options but may lack cardinal information concerning those comparisons. Contrary to majoritarian principles, most people p...

By Iacopo Morchio and Christian Moser

American Economic Review, May 2026

Using linked employer-employee data from Brazil, we document a significant gender pay gap, which is largely attributed to women working at lower-paying employers. To interpret this fact, we develop an equilibrium search model with endogenous firm pay, ame...

Efficiency Criteria, Income Taxation, and Heterogeneous Elasticities

American Economic Review, May 2026

A common interpretation of Pareto-efficient policies is that, for some cardinal utility representations of preferences, they maximize utilitarian welfare. We show in the context of income taxation that such cardinalizations are often extreme, requiring un...

By Noor Kumar, Uyseok Lee, Matt Lowe, and Olaitan Ogunnote

American Economic Review, May 2026

Weekly lotteries determine which politicians ask the UK prime minister a question in front of a male-dominated, noisy chamber. Lottery winners receive 4 percent higher vote margin in the next election, but women are 12 percent less likely to submit questi...
