During the past forty years, the simultaneous, symbiotic growth of financial innovation, disintermediation and deregulation has created an environment with extremely complex, opaque investment instruments. That system has now collapsed. At the very center of the crisis are a small group of...

This study develops and evaluates a model that generates synthetic credit ratings using accounting and market based information. The model performs very well in explaining agency ratings, suggesting that fitted values for unrated companies are likely to be reasonably precise. In addition, the...

This paper explores the implications of systemic risk in Credit Structured Finance (CSF). Risk measurement issues loomed large during the 2007-08 financial crisis, as the massive, unprecedented number of downgrades of AAA senior bond tranches inflicted severe losses on banks, calling into...

The role of credit rating agencies has been questioned in the recent years. Existing empirical studies provide mixed evidence on the informational value of bond ratings for financial investors. In this study we examine the relationship between bond ratings and credit spreads for US corporate...

Using an international sample of more than 65,000 rating actions by Fitch, Moody's and S&P, we analyze the effect of the Dodd-Frank Act on credit ratings. We document that (i) rating report content changes significantly after Dodd-Frank and (ii) show, by exploiting within firm-quarter variation,...

Relying on a perspective borrowed from monetary policy announcements and introducing an econometric twist in the traditional event study analysis, we document the existence of an "event risk transfer", namely a significant credit risk transmission from the sovereign to the corporate sector after...

Certifiers contribute to the sound functioning of markets by reducing a symmetric information. They, however, have been heavily criticized during the 2008-09 financial crisis. This paper investigates on which side of the market a monopolistic profit-maximizing certifier offers his service. If...

We develop a four-factor model intended to capture size, value, and credit rating transition patterns in excess returns for a panel of predominantly mid- and large-cap entities. Using credit transition matrices and rating histories from 48 US issuers, we provide evidence to support a...
