Tim Xiao: This paper argues that the reduced-form jump diffusion model may not be appropriate for credit risk modeling. To correctly value hybrid defaultable financial instruments, e.g., convertible bonds, we present a new framework that relies on the probability distribution of a default jump...

We present a flexible approach for the valuation of interest rate derivatives based on affine processes. We extend the methodology proposed in Keller-Ressel et al. (in press) by changing the choice of the state space. We provide semi-closed-form solutions for the pricing of caps and floors. We...

This study provides a rigorous empirical comparison of structural and reduced-form credit risk frameworks. As major difference we focus on the discriminative modeling of default time. In contrast to previous literature, we calibrate both approaches to bond and equity prices. By using same input...

This paper focuses on the key credit risk parameter Loss Given Default (LGD). We describe its general properties and determinants with respect to seniority of debt, characteristics of debtors or macroeconomic conditions. Further, we illustrate how the LGD can be extracted from market observable...

The ground-breaking Black-Scholes-Merton model has brought about a generation of derivative pricing models that have been successfully applied in the financial industry. It has been a long standing puzzle that the structural models of credit risk, as an application of the same modeling paradigm,...

Using a sample of 161 global banks in 23 countries, we examine the applicability of structural models and bank fundamentals to price global bank credit risk. First, we find that variables predicted by structural models (leverage, volatility, and risk-free rate) are significantly associated with...

It has been a long standing puzzle that the structural models of credit risk, as an application of the same modeling paradigm,...

In recent years, a liquid market for options on a broad credit default swap index (CDX) has developed. We study the extent to which these options are priced consistently with options on a broad equity index (SPX). We consider a rich structural credit risk model in which firm assets follow a...

This paper investigates predictions of structural credit risk models for interest rate sensitivities of corporate bond returns. Recent evidence has shown that the existing models fail to capture this sensitivity (a stylized fact referred to as the interest rate sensitivity puzzle). We propose...

This paper propses a contingent claims model to value a firm's debt and equity as functions of observable book values appearing in published financial statements. Equity fair value critically depends on expected earnings, equity book value and earnings volatility, because of the options to...
