Document Details : Title: On the Moments of Aggregate Discounted Claims with Dependence Introduced by a FGM Copula Author(s): BARGÈS, Mathieu , COSSETTE, Hélène , LOISEL, Stéphane , MARCEAU, Étienne Journal: ASTIN Bulletin Volume: 41 Issue: 1 Date: 2011 Pages: 215-238 DOI: 10.2143/AST.41.1.2084392 Abstract : In this paper, we investigate the computation of the moments of the compound Poisson sums with discounted claims when introducing dependence between the interclaim time and the subsequent claim size. The dependence structure between the two random variables is defined by a Farlie-Gumbel-Morgenstern copula. Assuming that the claim distribution has finite moments, we give expressions for the first and the second moments and then we obtain a general formula for any mth order moment. The results are illustrated with applications to premium calculation and approximations based on moment matching methods. |
