Abstract. An insurance activity model that allows to evaluate the duration of the negative surplus is presented in this paper. Assuming the surplus process as continuing if ruin occurs, we consider how long this process will stay below zero. The compound Poisson continuous time surplus process is used for the model development. Analytical formulas are obtained for estimating the expected value ...

Prepaid customers in mobile telecommunications are not bound by a contract and can therefore change operators (‘churn’) at their convenience and without notification. This makes the task of predicting prepaid churn both challenging and financially rewarding. This paper presents an explorative, real world study of prepaid churn modeling by varying the experimental setup on three dimensions: data...
