Abstract:In this paper, we define new stochastic orders in higher dimensions called weak correlation orders. It is shown that weak correlation orders imply stop-loss order of sums of multivariate dependent risks with same marginals. Moreover, some properties and relations of stochastic orders are discussed. | |||

Abstract:Let ${ec{X}_{k}, k geq 1}$ be a sequence ofindependent identically distributed non-negative random vectors withcommon marginal distributions $F_{1}$, $F_{2}$ having extendedregularly varying tails, joint distribution function $F_{1,2}$ andfinite mean $ec{mu}=epec{X}_{1}$. The two components of$ec{X}_{1}$ are allowed to be dependent. Under some mildassumptions, precise large deviations for both the partial sums$ec{S}_{n}=sum_{k=1}^{n}ec{X}_{k}$ and the random sums$ec{S}_{N(t)}=sum_{k=1}^{N(t)}ec{X}_{k}$ are investigated,where $N(t)$ is a counting process independent of the sequence${ec{X}_{k}, k geq 1}$. | |||

Abstract:The computation of the bilateralcounterparty valuation adjustment of CDS is in effect the modelingof the default correlation between the investor, the protectionseller, and the reference entity. We present a contagion model,where defaults of three parties are all driven by a commoncontinuous-time Markov process. We give the explicit formula for thebilateral credit valuation adjustment (CVA) of the CDS and examinethe effect of the regime switching on the CVA. | |||

Abstract:A scale-free tree with the parameter β is very close to a star if βis just a bit larger than -1, whereas it is close to a randomrecursive tree if β is very large. Through the Zagreb index, the whole scene of the evolution of the scale-free trees model is consideredas β goes from -1 to +∞. And the first two moments and the asymptotic behaviors of this index of a scale-free tree are obtained for all β>-1. | |||

Abstract:This paper investigates the hitting timeand the last exit time of a Cox risk process whose intensity processis a markovian jump process. By a ``backward differential argument"and the Markov property of the intensity process, we derive theintegro-differential equation satisfied by the Laplace transform ofthe hitting time. Exact solution to this equation could beconstructed by the probability method. Further, we investigate thesituation when the intensity process is an n-state Markov process | |||
