SPECIFICATION ANALYSIS OF STRUCTURAL CREDIT RISK MODEL WITH STOCHASTIC VOLATILITY

Specification Analysis of Structural Credit Risk Models

In this paper we conduct a specification analysis of structural credit risk models, using term structure of credit default swap (CDS) spreads and equity volatility from high-frequency return data. Our study provides consistent econometric estimation of the pricing model parameters and specification tests based on the joint behavior of time-series asset dynamics and cross-sectional pricing error...

Modeling the Dynamics of Credit Spreads with Stochastic Volatility

This paper investigates a two-factor affine model for the credit spreads on corporate bonds. The Þrst factor can be interpreted as the level of the spread, and the second factor is the volatility of the spread. The riskless interest rate is modeled using a standard two-factor affine model, thus leading to a four-factor model for corporate yields. This approach allows us to model the volatility ...

A Risk-Neutral Stochastic Volatility Model

We construct a risk-neutral stochastic volatility model using no-arbitrage pricing principles. We then study the behavior of the implied volatility of options that are deep in and out of the money according to this model. The motivation of this study is to show the diierence in the asymptotic behavior of the distribution tails between the usual Black-Scholes log-normal distribution and the risk...

Bayesian Analysis of a Stochastic Volatility Model

A Structural Model for Sovereign Credit Risk

This paper provides, and empirically estimates, a structural model of sovereign default risk on external debt. The sovereign endogenously determines its level of foreign debt and default policy. Consistent with default crisis episodes, the sovereign and its lenders bargain at default over a reduction of the debt service. The potential for debt restructuring o¤ers the sovereign greater incentive...
