We define a new approach to manage prepayment, default and interest rate risks simultaneously in some standard asset-backed securities structures. We propose a parsimonious top-down approach, by modeling directly the portfolio loss process and the amortization process. Both are correlated to...

We provide a rigorous proof of granularity adjustment (GA) formulas to evaluate loss distributions and risk measures (value-at-risk) in the case of heterogenous portfolios, multiple systematic factors and random recoveries. As a significant improvement with respect to the literature, we detail...

In competing risks model, several failure times arise potentially. The smallest failure time and its index only are observed. Without specific assumptions, the joint or even the marginal distribution functions of the underlying failure times are not identifiable (A. Tsiatis, Proc. Natl. Acad....

[fre] Réduction collective et individuelle du temps de travail : que souhaitent les salariés ? En mars 1995, moins d'un quart des salariés à temps complet se déclarent prêts à réduire proportionnellement leur temps de travail et leur salaire. Les plus aisés, les plus diplômés, et les...

[fre] Les rythmes de travail hors norme. Travailler sept ou huit heures par jour, du lundi au vendredi et aux mêmes horaires toute l'année, demeure encore la norme. Cependant, trois actifs sur dix ont connu, en 1 995, un rythme de travail autre : irrégularité des jours ou, des horaires de...

The data consists of multivariate failure times under right random censorship. By the kernel smoothing technique, convolutions of cumulative multivariate hazard functions suggest estimators of the so-called multivariate hazard functions. We establish strong i.i.d. representations and uniform...

This paper defines two distribution free goodness-of-fit test statistics for copulas. It states their asymptotic distributions under some composite parametric assumptions in an independent identically distributed framework. A short simulation study is provided to assess their power performances.
