Abstract

The first method, essentmlly due to GOOVAERTS and DE VYLDER, uses the

connection between the probabiliy of ruin and the maximal aggregate loss random

variable, and the fact that the latter has a compound geometric distribution.

For the second method, the claim amount distribution is supposed to be a

combination of exponential or translated exponential distributions. Then the

probability of ruin can be calculated in a transparent fashion; the main problem

is to determine the nontrivial roots of the equation that defines the adjustment

coefficient. For the third method one observes that the probability of ruin is

related to the stationary distribution of a certain associated process. Thus it can

be determined by a single simulation of the latter. For the second and third

methods the assumption of only proper (positive) claims is not needed.
