"We conduct a systematic comparison of confidence intervals around estimated probabilities of default (PD), using several analytical approaches from large-sample theory and bootstrapped small-sample confidence intervals. We do so for two different PD estimation methods--cohort and duration...

In 2002, the Securities and Exchange Commission mandated that the chief executive officers of large, publicly traded firms certify the accuracy of their company financial statements. In this paper, I investigate whether CEO certification has had a measurable effect on the stock market valuation...

In response to the sharp decline in prices of financial stocks in the fall of 2008, regulators in a number of countries banned short selling of particular stocks and industries. Evidence suggests that these bans did little to stop the slide in stock prices, but significantly increased costs of...

More than three-quarters of U.S. households bear consumer debt, yet we have little understanding of the relationship between financial education and the debt behavior of U.S. consumers. In this paper, we study the effects of exposure to financial training on debt outcomes in early adulthood....

We study credit ratings on subprime and Alt-A mortgage-backed-securities (MBS) deals issued between 2001 and 2007, the period leading up to the subprime crisis. The fraction of highly rated securities in each deal is decreasing in mortgage credit risk (measured either ex ante or ex post),...

In this paper, we provide an overview of the subprime mortgage securitization process and the seven key informational frictions that arise. We discuss the ways that market participants work to minimize these frictions and speculate on how this process broke down. We continue with a complete...

We conduct a systematic comparison of confidence intervals around estimated probabilities of default (PD), using several analytical approaches from large-sample theory and bootstrapped small-sample confidence intervals. We do so for two different PD estimation methods-cohort and duration...

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...
