Abstract:
In this work, we discuss the stochastic comparison of two classical surplus processes in a one-year insurance period. Under the Marshall–Olkin extended exponential random aggregate claim amounts, we extend one result of Khaledi and Ahmadi [J. Statist. Plann. Inference, 138 (2008), pp. 2243–2251]. Applications of our results to the value-at-risk and ruin probability are also given. Our results show that the heterogeneity of the risks in a given insurance portfolio tends to make the portfolio volatile, which in turn leads to requiring more capital.
Keywords:
Marshall–Olkin extended exponential distribution, usual multivariate stochastic order, multivariate chain majorization, order statistics, hazard rate function, aggregate claim amounts, value-at-risk, ruin probability.
