Sums of pairwise quasi-asymptotically independent random variables with consistent variation

Y Chen, KC Yuen - Stochastic Models, 2009 - Taylor & Francis
This article investigates the tail asymptotic behavior of the sum of pairwise quasi-
asymptotically independent random variables with consistently varying tails. We prove that …

Tail behavior of the product of two dependent random variables with applications to risk theory

Y Yang, Y Wang - Extremes, 2013 - Springer
Let the random vector (X, Y) follow a bivariate Sarmanov distribution, where X is real-valued
and Y is nonnegative. In this paper we investigate the impact of such a dependence …

Tail asymptotics for the sum of two heavy-tailed dependent risks

H Albrecher, S Asmussen, D Kortschak - Extremes, 2006 - Springer
Let X 1, X 2 denote positive heavy-tailed random variables with continuous marginal
distribution functions F 1 and F 2, respectively. The asymptotic behavior of the tail of X 1+ X 2 …

The finite-time ruin probability with dependent insurance and financial risks

Y Chen - Journal of Applied Probability, 2011 - cambridge.org
Consider a discrete-time insurance risk model. Within period i, the net insurance loss is
denoted by a real-valued random variable X i. The insurer makes both risk-free and risky …

Uniform tail asymptotics for the stochastic present value of aggregate claims in the renewal risk model

Q Tang, G Wang, KC Yuen - Insurance: Mathematics and Economics, 2010 - Elsevier
Consider an insurer who is allowed to make risk-free and risky investments. The price
process of the investment portfolio is described as a geometric Lévy process. We study the …

The distribution of the sum of dependent risks is a crucial aspect in actuarial sciences, risk
management and in many branches of applied probability. In this paper, we obtain analytic …

Tail risk measures and risk allocation for the class of multivariate normal mean–variance mixture distributions

JHT Kim, SY Kim - Insurance: Mathematics and Economics, 2019 - Elsevier
