The financial crisis of 2007-09 has sparked keen interest in models of financial frictions and their impact on macro activity. Most models share the feature that borrowers suffer a contraction in the quantity of credit. However, the evidence suggests that although bank lending contracted during...

A fundamental conclusion drawn from the recent financial crisis is that the supervision and regulation of financial firms in isolation - a purely microprudential perspective - are not sufficient to maintain financial stability. Rather, a macroprudential perspective, which evaluates and responds...

The pattern of disagreement between bond raters suggests that bank and insurance firms are inherently more opaque than other firms. Moody's and Standard and Poor's split more frequently over these financial intermediaries, and the splits are more lopsided, as theory here predicts. Uncertainty...

We identify and track over time the factors that make the financial system vulnerable to fire sales by constructing an index of aggregate vulnerability. The index starts increasing quickly in 2004, before most other major systemic risk measures, and triples by 2008. The fire-sale-specific...

I study the effects of an increase in the supply of local mortgage credit on local house prices and employment by exploiting a natural experiment from Switzerland. In mid-2008, losses in U.S. security holdings triggered a migration of dissatisfied retail customers from a large, universal bank,...

Banks are regulated more than most firms, making them good subjects to study regulatory arbitrage (avoidance). Their latest arbitrage opportunity may be the new leverage rule covering the largest U.S. banks; leverage rules require equal capital against assets with unequal risks, so banks can...

We find that competition from payday lenders leads depository institutions to raise overdraft fees and reduce the availability of “free” checking accounts. We attribute this rise in prices partly to adverse selection created by banks’ practice of charging a flat fee regardless of the...

The value of assets in the digital ecosystem has grown rapidly amid periods of high volatility. Does the digital financial system create new potential challenges to financial stability? This paper explores this question using the Federal Reserve’s framework for analyzing vulnerabilities in the...

We provide a critical review of the empirical and theoretical literature on bank supervision. The review focuses on microprudential supervision: the supervision of individual banking institutions aimed at assessing the financial and operational health of those firms. Theory suggests that...

Using highly detailed data on the loan portfolios of large U.S. banks, we document that these banks "specialize" by concentrating their lending disproportionately into one industry. This specialization improves a bank’s industry-specific knowledge and allows it to offer generous loan terms to...
