Résumé
In this paper, we consider an extension of the classical risk model. A tail dependence structure between claim amounts and inter-loss times with a Brownian disturbance is introduced via the Spearman copula in order to evaluate the Gerber-Shiu functions and the loss probabilities. Integro-differential equations are derived for the Gerber-Shiu function, from which expressions for the Laplace transforms of the time to ruin and the deficit at ruin are obtained, assuming exponential claim amounts.
