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...

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 article provides a generalized two-firm model of default correlation, based on the structural approach that incorporates interest rate risk. In most structural models default is driven by the firms' asset dynamics. In this article, a two-firm model of default is instead driven by the...
