Results well known in the actuarial community about closed-form expressions to Gompertz and Gompertz-Makeham life expectancies for a person aged x are still being independently rediscovered this day. This note seeks acknowledge previous results expectancies, especially science field, hoping stimulate interdisciplinarity provide background further developments, since derivation of expectancy (an...

Abstract In most industrialised countries, one of the major societal challenges is demographic change coming along with ageing population. The increasing life expectancy observed over last decades underlines importance to find ways appropriately cover financial needs elderly.

Abstract In this paper, we recall actuarial and financial applications of sums dependent random variables that follow a non-Gaussian mean-reverting process contemplate distribution approximations. Our work complements previous related studies restricted to lognormal variables; revisit approximations suggest new ones. We then derive moment-based for attuned Asian option pricing computation risk ...
