摘  要: In insurance risk management, modelling of a dependence structure between different type of risks is a critical task for both practicing actuaries and academics. This paper considers a discrete-time risk model by introducing a temporal dependence between the number of claims. The risk model is based on INAR(1) process with various kind of innovations, which allows equal-dispersion, over-dispersion and zero-inflation. We investigate the moment generating function of the discounted aggregate claim amount within this framework. With mixed Erlang claim size, related risk measures such as the stop-loss premium, VaR and TVaR are discussed. The findings are illustrated by numerical examples.
