Excess of loss reinsurance and Gerber’s inequality in the Sparre Andersen model. (Excess of loss reinsurance and Gerber’s inequality in the Sparre Anderson model.) (English) Zbl 1074.91567

Summary: Assuming that the reinsurance premium is calculated according to the expected value principle we study an upper bound for the probability of ruin in finite horizon, as function of the excess of loss retention limit. The upper bound used is an extension proved by J. Grandell [Aspects of Risk Theory. New York: Springer (1991; Zbl 0717.62100)] of Gerber’s bound, see [H. U. Gerber, Mitt. Verein. Schweiz. Versicherungsmath. 73, 205–216 (1973; Zbl 0278.60047)], for the Sparre Andersen model [“On the collective theory of risk in the case of contagious between the claims”, in: Proceedings of the Transactions on XV International Congress of Actuaries, New York (1957)].
