This paper is concerned with the problem of ruin in the classical compound binomial and compound Poisson risk models. Our primary purpose is to extend to those models an exact formula derived by Picard and Lefèvre (1997) for the probability of (non-)ruin within finite time. First, a standard...

We propose an effective equity model adapted for medium term and long term risk assessment. One of its specific aspects is to allow an asymetrical dampening of the equity risk (called the dampener effect) conditional to the cyclical level of equity prices and to enable accurate Value At Risk...
