Default dependence among corporate bond issuers: empirical evidence from time series data
This study shows that the extent to which the asset returns of different obligors are correlated is of vital importance for a realistic assessment credit portfolio risk. The high empirical relevance of this phenomenon is demonstrated by applying a likelihood-based estimation procedure to time series data on historical default frequencies. It turns out that, apparently, the default probabilities of speculative-grade debtors are much more highly correlated than the ones of investment-grade borrowers.
