Description: This paper presents a new approach for pricing insurance contracts. The approach is based both on economic and probabilistic arguments. The novel property of this paper is that the pricing argument is based on two factors determining the insurer's expected profit: the first one is the net revenue from selling insurance contracts and the second is the possible loss due to insolvency. From the Actuarial Research Clearing House ARCH 1997 Vol. 1.

Description: We propose an age-shift model to modify the LC model and deal with the problem of parameters. The proposed method attains smaller estimation errors with respect to mean absolute percentage error or mean square error. We also apply the proposed age-shift model to the mortality rates of these four countries to evaluate the longevity risk in annuity products by measuring life expectancy.
