Theoretical credit risk models a la Merton (1974) predict a non-linear negative link between a firm's default likelihood and asset value. This motivates us to propose a flexible empirical Markov-switching bivariate copula that allows for distinct time-varying dependence between credit default...

Basel III seeks to improve the financial sector's resilience to stress scenarios which calls for a reassessment of banks' credit risk models and, particularly, of their dependence on business cycles. This paper advocates a Mixture of Markov Chains (MMC) model to account for stochastic business...

We analyze the channels for the cross-border propagation of sovereign credit risk in the international sovereign debt market. We study sovereign credit contagion through the immediate effects of credit events as defined by CDS spread jumps on the credit spreads of other regional sovereigns and...

This paper examines the quarter-ahead out-of-sample predictability of Brazil, Mexico, the Philippines and Turkey credit spreads before and after the Lehman Brothers' default. A model based on the country-specific credit spread curve factors predicts no better than the random walk and slope...
