I develop a model where the sovereign debt capacity depends on the capitalization of domestic banks. Low-capital banks optimally tilt their government bond portfolio toward domestic securities, linking their destiny to that of the sovereign. If the sovereign risk is sufficiently high,...

I develop a model where governments might prefer to have an undercapitalized domestic financial sector during crises. Weak banks optimally tilt their sovereign bond portfolio towards domestic securities that are positively correlated with banks' other sources of revenues. Governments anticipate...

We find that banks differ in their propensity to lend to minorities based on their stakeholders' aversion to inequality. Using mortgage application data collected under the Home Mortgage Disclosure Act, we document a large and persistent cross-sectional variation in banks' propensity to lend to...

Amid the current U.S.-China technological race, the U.S. has imposed export controls to deny China access to strategic technologies. We document that these measures prompted a broad-based decoupling of U.S. and Chinese supply chains. Once their Chinese customers are subject to export controls,...

We study the design of lender of last resort interventions and show that the provision of long-term liquidity incentivizes purchases of high-yield short-term securities by banks. Using a unique security-level data set, we find that the European Central Bank's three-year Long-Term Refinancing...

I develop a model where the sovereign debt capacity depends on the capitalization of domestic banks. Low-capital banks optimally tilt their government bond portfolio toward domestic securities, linking their destiny to that of the sovereign. If the sovereign risk is sufficiently high,...

We document capital misallocation in the U.S. investment-grade (IG) corporate bond market, driven by quantitative easing (QE). Prospective fallen angels - risky firms just above the IG rating cutoff-enjoyed subsidized bond financing since 2009, especially when the scale of QE purchases peaked...

We document the propagation effects through supply chains of the most damaging cyberattack in history and the important role of banks in mitigating its impact. Customers of directly hit firms saw reductions in revenues, profitability, and trade credit relative to similar firms. The losses were...

We show that "zombie credit" - cheap credit to impaired firms - has a disinflationary effect. By helping distressed firms to stay afloat, such credit creates excess production capacity, thereby putting downward pressure on product prices. Granular European data on inflation, firms, and banks...
