David GlancyLoan modifications can either amplify or mitigate credit losses depending on the strategy lenders employ. Using detailed supervisory data and a model incorporating various frictions that could encourage modifications (liquidity constraints, foreclosure costs, and loss recognition costs), I assess why banks extend CRE loans. I find that extensions predominantly address temporary payment frictions, both in normal times and following the Spring 2023 bank stress episode.

Benjamin Knox and Annette Vissing-JorgensenWe survey and extend work on the Federal Reserve’s effect on the stock market, focusing on three empirical findings: The effect of monetary policy surprises in a narrow window around announcements from the Federal Open Market Committee (FOMC), the pre-FOMC announcement drift, and the FOMC cycle in stock returns.

Pawel M. Krolikowski and Andrew H. McCallumWe study tariffs in a general equilibrium dynamic model with search frictions between heterogeneous exporting producers and importing retailers. We show the model has a unique equilibrium and analytically characterize home unilateral import tariffs that maximize welfare given a passive foreign country.

Anne Lundgaard HansenThis paper proposes a validation framework for LLM-generated measurements when reliable benchmarks are unavailable. Validity is established by testing whether an LLM can reconstruct passages from annotated labels while maintaining semantic consistency with the original text. The framework avoids circular reasoning by establishing testable prerequisite properties that must be met for a validation to be considered successful.
