1 Life Insurance Model In order to model a life insurance policy we consider a person aged x and denote by T the future life span and we remark that actually one would have to denote it T (x) since it is dependent on the age x. 1) and we assume that there exists a probability density function for T. Hence we can write: g(t)dt = P [t < T < t + dt]. 8) 0 ◦ and we remark that ex is the expected future life span of a person aged x. We also remark that qx := 1 qx and px := 1 px . Based on the above definitions we get the following equations: t qx+s = Gx+s (t) = P [T (x + s) < t] G(s + t) − G(s) , 1 − G(s) 1 − G(s + t) , t px+s = P [T ≥ s + t|T > s] = 1 − G(s) s+t px = 1 − G(s + t) 1 − G(s + t) = s px t px+s , = (1 − G(s)) 1 − G(s) s|t qx = G(s + t) − G(s) = P [T (x) ≤ s + t|T (x) > s] = G(s + t) − G(s) = s px t qx+s .
