Default Dependence: The Equity Default Relationship

Abstract

Les auteurs étudient la relation non linéaire entre les prix des actions et les primes de swaps sur défaillance dans le cadre de trois modèles structurels qui formalisent le processus d'évolution du prix des actions et qui se différencient par leur spécification du seuil de défaillance. Ils estiment et comparent ces modèles à partir de données relatives aux primes de swaps sur défaillance et aux prix des actions d'un éventail d'entreprises. Ils constatent que le modèle à seuil stochastique présente une meilleure adéquation statistique et permet de mieux prévoir les primes de swaps hors échantillon que les modèles à seuil constant et à seuil incertain. Les auteurs mettent aussi en évidence l'existence d'un lien entre, d'une part, le seuil de défaillance, l'intensité du saut et la volatilité du seuil estimés à l'aide de leurs modèles et, d'autre part, des variables indicatrices du risque de défaillance propre à l'entreprise telles que la cote de crédit de celle-ci, la volatilité du prix de ses actions et ses ratios de levier.

The paper examines three equity-based structural models to study the nonlinear relationship between equity and credit default swap (CDS) prices. These models differ in the specification of the default barrier. With cross-firm CDS premia and equity information, we are able to estimate and compare the three models. We find that the stochastic barrier model performs better than the constant and uncertain barrier models in terms of both in-sample fit and out-of-sample forecasting of CDS premia. In addition, we demonstrate a linkage between the default barrier, jump intensity, and barrier volatility estimated from our models and firm-specific variables related to default risk, such as credit ratings, equity volatility, and leverage ratios.
