Disruptions to Foreign Trade and U.S. Banks’ Returns
We develop a market-based measure of firms' and industries' exposure to foreign trade disruptions. Combining this approach with detailed supervisory data, we quantify large U.S. banks' exposure to such disruptions and propose a novel bank-level vulnerability index. We show that banks with greater exposure experienced significantly larger stock price declines following the April 2025 tariff announcements. Our vulnerability index explains 18% of the cross-sectional variation in bank returns during this episode.

Regulating Financial Networks Under Uncertainty
I study the problem of regulating a network of interdependent financial institutions that is prone to contagion when there is uncertainty regarding its precise structure. I show that such uncertainty reduces the scope for welfare-improving interventions. While improving network transparency potentially reduces this uncertainty, it does not always lead to welfare improvements. Under certain conditions, regulation that reduces the risk-taking incentives of a small set of institutions can improve welfare. The size and composition of such a set crucially depend on the interplay between (i) the ...

Firm Networks and Asset Returns
This paper argues that changes in the propagation of idiosyncratic shocks along firm networks are important to understanding variations in asset returns. When calibrated to match key features of supplier-customer networks in the United States, an equilibrium model in which investors have recursive preferences and firms are interlinked via enduring relationships generates long-run consumption risks. Additionally, the model matches cross-sectional patterns of portfolio returns sorted by network centrality, a feature unaccounted for by standard asset pricing models.

Supply Chain Risk and Bank Lending Amid Trade Policy Uncertainty
During times of increased trade policy uncertainty and geopolitical tensions, supply chain disruptions can be an important source of instability. Due to the interconnected nature of modern economies, problems in one market can often ripple across others, triggering logistical bottlenecks and longer delivery times.

The Dynamics of the U.S. Overnight Triparty Repo Market
The overnight segment of the triparty repurchase agreement (repo) market plays a pivotal role in the normal functioning of the U.S. financial system by acting as an important source of secured short-term funding and supporting the liquidity of key fixed income markets, including U.S. Treasury and agency securities. This over-the-counter market accounts for over $1 trillion in daily transactions and provides a unique venue in which a diverse set of market participants invest their cash as well as obtain short-term funding.

Imperfect Information Transmission from Banks to Investors: Macroeconomic Implications
Our goal is to elucidate the interaction of banks' screening effort and strategic information production in loan-backed asset markets using a general equilibrium framework. Asset quality is unobserved by investors, but banks may purchase error-prone ratings. The premium paid on highly rated assets emerges as the main determinant of banks' screening effort. The fact that rating strategies reflect banks' private information about asset quality helps keep this premium high. Conventional regulatory policies interfere with this decision margin, thereby reducing signaling value of high ratings and ...

Imperfect Information Transmission from Banks to Investors: Macroeconomic Implications
We study the interaction of information production in loan-backed asset markets and credit allocation in a general equilibrium framework. Originating banks can screen their borrowers, but can inform investors of their asset type only through an error-prone rating technology. The premium paid on highly rated assets emerges as the main determinant of screening effort. Because the rating technology is imperfect, this premium is insufficient to induce the efficient level of screening. However, the fact that banks know their asset quality and produce ratings accordingly helps keep the premium ...
