The Real Effects of Sovereign Credit Rating Downgrades∗
We study the effect of sovereign credit rating downgrades on firm investment and financial policy. We identify causal effects by exploiting the effect of sovereign downgrades on corporate ratings that is due to sovereign ceiling policies followed by rating agencies. We find that sovereign downgrades lead to greater decreases in investment and leverage of firms that are at the sovereign rating b...

Before the outbreak of the financial crisis, market participants did not differentiate between credit risk born by individual states despite different lev...
متن کاملOn sovereign credit migration: A study of alternative estimators and rating dynamics
This paper investigates the finite-sample behaviour of sovereign credit migration estimators and analyzes the properties of the rating process. Through bootstrap simulations, we compare a discrete multinomial estimator and two continuous hazard rate methods which differ in that one neglects time heterogeneity in the rating process whereas the other accounts for it. The study is based on Moody’s...
متن کاملA process model to develop an internal rating system: Sovereign credit ratings
The Basel II capital accord encourages financial institutions to develop rating systems for assessing the risk of default of their credit portfolios in order to better calculate the minimum regulatory capital needed to cover unexpected losses. In the internal ratings based approach, financial institutions are allowed to build their own models based on collected data. In this paper, a generic pr...
متن کاملPredicting Credit Rating and Credit Rating Changes: A New Approach
In this paper, we propose a hazard rate model for studying credit rating and credit rating changes. Theoretically the hazard rate model is more appropriate than the previous static models. Yet it is difficult to estimate hazard rate model, especially when the covariates are time-varying. This paper extends the results of Shumway(2001) and shows that a multiple-state hazard rate model can be est...
