To resolve the IPO underpricing puzzle it is essential to analyze who knows what when during the issuing process. In Germany, broker-dealers make a market in IPOs during the subscription period. We examine these pre-issue prices and find that they are highly informative. They are closer to the...

Using an asset-based model of default, I derive rating characteristics if ratings are meant to look 'through the cycle' as opposed to being based on the borrowers' current condition. The through-the-cycle method, which is employed by most rating agencies, requires a separation of permanent and...

Agency ratings and market-based measures of default risk are useful complements. Combining the two improves the prediction of defaults over the use of a single measure. While in-sample analysis suggests that one should give more weight to ratings as the horizon increases, or issuers become less...

This paper shows that the stock price of the rating agency Moody's reacts negatively to rating actions that are perceived to indicate low rating quality. The reaction is economically significant. The cumulative effect corresponds to a 20% loss in market capitalization. This suggests that market...

Recent literature has proposed new methods for measuring the systemic risk of financial institutions based on observed stock returns. In this paper we examine the reliability and robustness of such risk measures, focusing on CoVaR, marginal expected shortfall, and option-based tail risk...

This paper examines whether the stock price of the rating agency Moody’s reacts negatively to rating actions that could indicate low rating quality. The reaction to rating reversals, which Moody’s describes as particularly damaging to investors, is economically significant. It suggests that...

Rating agencies claim to look through the cycle when assigning corporate credit ratings, which entails that they are able to separate trend components of default risk from transitory ones. To test whether agencies possess this competence, I take market-based estimates of 1-year default...

A firm’s current leverage ratio is one of the core characteristics of credit quality used in statistical default prediction models. Based on the capital structure literature, which shows that leverage is mean-reverting to a target leverage, we forecast future leverage ratios and include them...
