Mortality models are fundamental to quantify mortality/longevity risks and provide the basis of pricing and reserving. In this paper, we consider a family of mortality jump models and propose a new generalized Lee-Carter model with asymmetric double exponential jumps. It is asymmetric in terms...

Mortality is a stochastic process. We have imprecise knowledge about the probability distribution of mortality rates in the future. Mortality risk, therefore, can be defined in a broad term of ambiguity. In this paper, we investigate the effects of ambiguity and ambiguity aversion on prices of...
