Financial markets provide an ideal frame for the study of first-passage time events of non-

Default Risk Modeling the First-Passage Approximation Extended Black-Cox Model
2010/10/18
We develop a generalization of the Black-Cox structural model of default risk. The extended model captures uncertainty related to firm's ability to avoid default even if company's liabilities momentar...

First passage event fluctuation theory ladder process multivariate L´ evy process
2010/11/3
For the sum process X = X1 + X2 of a bivariate L´evy process (X1,X2) with possibly dependent components, we derive a quintuple law describing the first upwards passage event of X over a fixed ba...
In this work we develop a tractable structural model with analytical default probabilities depending on a random default barrier and possibly random volatil-ity ideally associated with a scenario base...
