We study the endogenous information acquisition and withdrawal-redeposit decisions of individual agents when a liquidity event triggers a spreading rumor and therefore exposes a bank to a run. Uncertainty about the bank's liquidity and potential failure motivates agents who hear the rumor to...

We study information acquisition and dynamic withdrawal decisions when a spreading rumor exposes a solvent bank to a run. Uncertainty about the bank's liquidity and potential failure motivates depositors who hear the rumor to acquire additional noisy signals. Depositors with less informative...

How does the speed by which information diffuses affect its value to a stock market investor? In a structural model solved in closed-form, this speed has two opposing effects on the empirically dominant term of the value of information. Faster-diffusing information means quicker and less noisy...

We estimate the shadow cost of capital requirements using data on a costly loophole that allowed banks to relax these constraints. This loophole — liquidity guarantees to asset-backed commercial paper conduits — was exploited by the largest banks before the crisis of 2008. We show...

Hub-and-spoke regulation, where a central regulator with legal power over firms delegates monitoring to local supervisors, can improve information collection, but can also lead to agency problems and capture. We document that following the closure of a US bank regulator's field offices, the...

We use a text-based measure of popular sentiment toward finance to study how finance sentiment responds to rare historical disasters and to the ongoing COVID-19 pandemic. Finance sentiment declines after epidemics and earthquakes, but rises following severe droughts, floods, and landslides....

We evaluate the Black-Litterman equilibrium model approach to portfolio choice. We quantify the improvement in portfolio performance of a privately informed investor who learns from market prices over an equally informed, but dogmatic investor who only uses private information. We extend the...

We propose an approach to measuring the state of the economy via textual analysis of business news. From the full text content of 800,000 Wall Street Journal articles for 1984{2017, we estimate a topic model that summarizes business news as easily interpretable topical themes and quantifies the...
