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,...

Despite the extensive attention that the Basel capital adequacy standards have received internationally, significant variation exists in the implementation of these standards across countries. Furthermore, a significant number of countries increase or decrease the stringency of capital...

I study how bank relationships affected the timing and geographic distribution of Paycheck Protection Program (PPP) lending. Half of banks' PPP loans went to borrowers within 2 miles of a branch, mostly driven by relationship lending. Firms near less active lenders shifted to fintechs and other...

We assess the effects of geographic expansion on bank efficiency using cost and profit efficiency for over 7,000 U.S. banks, 1993-1998. We find that parent organizations exercise some control over the efficiency of their affiliates, although this control tends to dissipate with distance to the...

We study how bank loan rates responded to a 50% increase in capital requirements for a subcategory of construction lending, High Volatility Commercial Real Estate (HVCRE). To identify this effect, we exploit variation in the loan terms determining whether a loan is classified as HVCRE and the...

This paper studies the role banking supervision plays in improving access to credit for minorities by investigating how enforcement decisions and orders (EDOs) affect the bank borrower base. We find that, after an EDO's termination, banks significantly increase residential mortgage lending to...

We study how competition between banks and non-banks affects lending standards. Banks have private information about some borrowers and are subject to capital requirements to mitigate risk-taking incentives from deposit insurance. Non-banks are uninformed and market forces determine their...

Banks add value by monitoring borrowers. High funding costs make banks reluctant to lend. A central bank can ease funding by purchasing loans, but cannot distinguish which loans require more or less monitoring, exposing it to adverse selection. A multi-tier loan pricing facility arises as the...

Did government mortgage programs mitigate the adverse economic effects of the financial crisis? We find that counties with greater participation in traditional government mortgage programs experienced less severe economic downturns during the Great Recession. In particular, counties with higher...

This paper examines the relationship between money market fund (MMF) risks and outcomes during crises, with a focus on the ABCP crisis in 2007 and the run on money funds in 2008. I analyze three broad types of MMF risks: portfolio risks arising from a fund's assets, investor risk reflecting the...
