This paper studies the discriminatory power and calibration quality of the structural credit risk models under the 'exogenous default boundary' approach including those proposed by Longstaff and Schwartz (1995) and Collin-Dufresne and Goldstein (2001), and 'endogenous default boundary' approach...

This paper assesses whether agency ratings and market-based default risk measures are consistent for East Asian banks during the period from 1996 to 2006. While the market-based measures are broadly consistent with the credit rating assessments for the banks in the developed economies, the...

This paper develops a simple model based on an options approach to measure provisions covering expected losses of collateralised retail lending due to default. The measurement of provisions against expected losses of retail lending secured by collateral is important for improving the capital...

Empirical findings and theoretical studies suggest that firms adjust toward time-varying target leverage ratios. This paper studies the performances of the default probabilities generated from two structural credit risk models (one with time-dependent leverage ratios and one with constant target...

This paper presents a benchmarking model for validation of default probabilities of listed companies for Basel II purposes. The model is based on the recent studies on the predictive capability of structural credit risk models. Benchmark ratings and one-year default probabilities are assigned to...
