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...

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...

We investigate the effect of credit analyst rotation in the context of long-term ratings of S&P 500 issuers between 2002 and 2015. We find that analyst rotation in the coverage of issuers is associated with higher rating activity and a lower credit risk assessment (e.g., rating downgrades)...
