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...

Central bank balance sheet expansion is financed by commercial banks. It involves not just a substitution of liquid central bank reserves for other assets held by commercial banks, but also a counterpart alteration in commercial bank liabilities, such as in short-term deposits issued to finance...

We build a model with heterogeneous firms and banks to analyze how policy affects credit allocation and long-term economic outcomes. When firms are hit by small negative shocks, conventional monetary policy can restore efficient bank lending and production by lowering interest rates. Large...

The crisis of 2007-09 has been characterized by a sudden freeze in the market for short-term, secured borrowing. We present a model that can explain a sudden collapse in the amount that can be borrowed against finitely-lived assets with little credit risk. The borrowing in this model takes the...

What is the effect of financial crises and their resolution on banks' choice of liquid asset holdings? When risky assets have limited pledgeability and banks have relative expertise in employing risky assets, the market for these assets clears only at fire-sale prices following a large number of...

We study the crash of bank stock prices during the COVID-19 pandemic. We find evidence consistent with a "credit line drawdown channel". Stock prices of banks with large ex-ante exposures to undrawn credit lines as well as large ex-post gross drawdowns decline more. The effect is attenuated for...

We analyze international trade and health policy coordination during a pandemic by developing a two-economy, two-sector trade model integrated into a micro-founded SIR model of infection dynamics. Disease transmission intensity can differ by goods (manufactured versus services and domestic...

When the Federal Reserve (Fed) expanded its balance sheet via quantitative easing (QE), commercial banks financed reserve holdings with deposits and reduced their average maturity. They also issued lines of credit to corporations. However, when the Fed halted its balance-sheet expansion in 2014...

We study an economy subject to recurrent disasters when agents have imprecise information about the frequency and duration of the disasters. Uncertainty about the persistence of states can lead to seemingly pessimistic behavior in bad times and optimistic behavior in good times. In a disaster,...

We explore the design of climate stress tests to assess and manage macro-prudential risks from climate change in the financial sector. We review the climate stress scenarios currently employed by regulators, highlighting the need to (i) consider many transition risks as dynamic policy choices;...
