Mortgage originators use credit score cutoff rules to determine how carefully to screen loan applicants. Recent research has hypothesized that these cutoff rules result from a securitization rule of thumb. Under this theory, an observed jump in defaults at the cutoff would imply that...

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...

Strategic default behavior suggests that the default process is not only a matter of inability to pay. Economic costs and benefits affect the incidence and timing of defaults. As with prior research, the authors find that people default strategically as their home value falls below the mortgage...

This editorial, which mirrors Bruce Jacobs's book Too Smart for Our Own Good: Ingenious Investment Strategies, Illusions of Safety, and Market Crashes, finds that “free-lunch” strategies and products that promise to increase returns while reducing risk can attract substantial investments and...

We analyze how the inflow of liquidity through TARP funds in the wake of the 2007/2008 financial crisis impacted banks' interbank market activity. We show that TARP banks increased interbank market activity statistically and economically in a very significant way. Their interbank lending...

Mortgage originators use credit score cutoff rules to determine how carefully to screen loan applicants. Recent research has hypothesized that these cutoff rules result from a securitization rule of thumb. Under this theory, an observed jump in defaults at the cutoff would imply that...

Credit score cutoff rules result in very similar potential borrowers being treated differently by mortgage lenders. Recent research has used variation induced by these rules to investigate the connection between securitization and lender moral hazard in the recent financial crisis. However, the...

Banks and other financial institutions which were too-big-to-fail (TBTF) played a central role during the Global Financial Crisis of 2007-2009. The present article lays out how misguided policies enabled banks to grow both in size as well as in complexity and therefore acquire TBTF status,...
