Self-similar processes in collective risk theory. (English) Zbl 0937.60029

Conditions are given for an insurance risk process to converge weakly to a long-range dependent process, in particular fractional Brownian motion. Convergence of the associated ruin probabilities is discussed and various estimates of the ruin probabilities for fractional Brownian motion are given. The occurrence of long-range dependence in insurance risk is motivated by an example with alternating periods of safe and risky conditions, along the lines of D. Heath, S. Resnick and G. Samorodnitsky [Ann. Appl. Probab. 9, No. 2, 352-375 (1999)].
