Calculating credit value adjustments can be very numerically intensive, often involving nested Monte Carlo simulations. Pierre Henry-Labordère uses marked branching diffusions to construct an efficient algorithm based on a Galton-Watson random tree,...
This paper analyzes the impact of several popular factor models on the calculation of value-at-risk (VaR) for the loss of a credit portfolio with many obligors. The study covers linear and nonlinear factor models focusing on the importance of tail dependence....
We propose two structural models for stochastic loss given default that allow the credit losses of a portfolio of defaultable financial instruments to be modeled. The credit losses are integrated into a structural model of default events accounting for...
We extend the framework of Leland, who proposed a structural model of rollover debt structure in a Black-Scholes framework.We apply this to the case of a doubleexponential jump-diffusion process, considering a trade-off model with firm risk, risk-free...
The Basel Accords have created the need to develop and implement models for probability of default (PD), loss given default (LGD) and exposure at default (EAD). Although PD is quite well researched, LGD and EAD lag behind in terms of both theoretical...
