We investigate lower and upper bounds for right tails (stop-loss premiums) of deterministic and stochastic sums of nonindependent random variables. The bounds are derived using the concepts of comonotonicity, convex order, and conditioning. The performance of the presented approximations is...

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...
