We analyze the evolution over time of portfolios of life insurance contracts referring to different cohorts or risk classes of insureds. We model the intensity of mortality as a random field, in order to capture cross-generations (risk classes) effects induced by the on-going management of...

We discuss the fair valuation of Guaranteed Annuity Options, i.e. options providing the right to convert deferred survival benefits into annuities at fixed conversion rates. The use of doubly stochastic stopping times and of affine processes provides great computational and analytical...

We consider a class of stochastic intensities of mortality that generalizes the model proposed by Lee and Carter (1992), allowing general diffusions to drive the mortality time-trend. We analyze the stability of such class of intensities under measure changes and show how a risk-neutral version...

We address the risk analysis and market valuation of life insurance contracts in a jump-diffusion setup. We exploit the analytical tractability of affine processes to deal simultaneously with financial and demographic risks affecting a wide range of insurance covers. We then focus on mortality...
