We develop an approximate solution method for a classical saving for retirement problem in case of random payment scheme and value at risk (VaR) defined investor preferences. As the results of our numerical calculations indicate our approximate approach provides greater accuracy and reduces...

In this paper we give some methods to set up confidence bounds for the discounted IBNR reserve. We start with a loglinear regression model and estimate the parameters by maximum likelihood such as given for example in Doray, 1996. The knowledge of the distribution function of the discounted IBNR...

In this paper we consider different approximations for computing the distribution function or risk measures related to a discrete sum of nonindependent lognormal random variables. Comonotonic upper bound and lower bound approximations for such sums have been proposed in Dhaene et al. (2002a,b)....
