Concentrating attention on the bivariate copula, we compare its behavior at the instant of default with its evolution between two defaults. The assumptions for our results will be expressed in terms of conditional hazard rates. publisher: Springer date: 2010 type: Book Section type: PeerReviewed identifier: Foschi, Rachele and Spizzichino, Fabio Dynamics of Dependence Properties for Lifetimes Influenced by Unobservable Environmental Factors.
