We investigate the problem of modeling defaults of dependent credits. In the framework of the class of structural default models we study threshold models where for each credit the underling ability-to-pay process is a transformation of a Wiener processes. We propose a model for dependent...

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...

Structural models have been developed and used in financial literature to assess the probability of default of corporations. This article aims at reversing this approach, using this probability as an input and investigating if the default barrier can be considered flat, as done in similar...

I empirically decompose sovereign credit spreads into a default-risk component and its associated (credit) risk premium and study the effect of political uncertainty on them. On average, credit risk premia account for 42 percent of the observed spreads in the European sovereign credit market. I...

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...

The objective of this paper is to consider defaultable term structure models in a general setting beyond standard risk-neutral models. Using as numeraire the growth optimal portfolio, defaultable interest rate derivatives are priced under the real-world probability measure. Therefore, the...

We derive a simple integral equation for the default probability over a finite time horizon of a company that makes coupon payments on its debt and infrequently returns to its leverage target by increasing its debt unless it defaults on its debt. Compared to the conventional (constant default...

In a default corridor [0,B] that the stock price can never enter, a deep out-of-the-money American put replicates a pure credit contract (Carr and Wu, 2011). Assuming discrete (one-period-ahead predictable) cash flows, we show an endogenous credit-risk model generates, along with the default...

We consider a situation in which general financial products such as options, CDS, and other derivatives, are traded to investigate the effect of cross-ownerships on market stability. We prove the existence and uniqueness of a clearing payment vector under the assumption of the fictitious default...

Extracting information from daily CDS spreads, we propose a measure of correlated default risk, which we show is a meaningful predictor of bankruptcy clusters. Focusing on U.S. corporate bonds, we also find that our measure of correlated default risk is more pronounced and commands a higher...
