We study early default, defined as serious delinquency or foreclosure in the first year, among nonprime mortgages from the 2001 to 2007 vintages. After documenting a dramatic rise in such defaults and discussing their correlates, we examine two primary explanations: changes in underwriting...

We document the emergence of a disconnect between mortgage and Treasury interest rates in the summer of 2003. Following the end of the Federal Reserve's expansionary cycle in June 2003, mortgage rates failed to rise according to their historical relationship with Treasury yields, leading to...

We summarize and evaluate Fannie Mae and Freddie Mac's credit risk transfer (CRT) programs, which have been used since 2013 to shift a portion of credit risk on more than $1.8 trillion of mortgages to private sector investors. We argue that the CRT programs have been successful in reducing the...

We study bank supervision by combining a theoretical model that distinguishes supervision from regulation and a novel dataset on work hours of Federal Reserve supervisors. We highlight the trade-offs between the benefits and costs of supervision and use the model to interpret the relationship...

We define predatory lending as a welfare-reducing provision of credit. Using a textbook model, we show that lenders profit if they can tempt households into “debt traps,” that is, overborrowing and delinquency. We then test whether payday lending fits our definition of predatory. We find...
