In this paper,11Version of 2012/07/08. we are interested in the optimization of computing time when using Monte-Carlo simulations for the pricing of the embedded options in life insurance contracts. We propose a very simple method which consists in grouping the trajectories of the initial...

The Solvency 2 advent and the best-estimate methodology in future cash-flows valuation lead insurers to focus particularly on their assumptions. In mortality, hypothesis are critical as insurers use best-estimate laws instead of standard mortality tables. Backtesting methods, i.e. ex-post...

We consider the problem of the global minimization of a function observed with noise. This problem occurs for example when the objective function is estimated through stochastic simulations. We propose an original method for iteratively partitioning the search domain when this area is a nite...

Dans cet article, nous mettons en évidence les principales composantes d'un générateur de scénarios économiques (GSE) que ce soit au niveau de sa conception théorique ou au niveau de sa mise en oeuvre pratique. Le choix de ces composantes est supposé être lié à la vocation finale du...

We are interested in modeling the mortality of long-term care (LTC) claimants having the same level of severeness (heavy claimant). Practitioners often use empirical methods that rely heavily on expert opinions. We propose approaches not depending on an expert’s advice. We analyze the...

Business and credit cycles have an impact on credit insurance, as they do on other businesses. Nevertheless, in credit insurance, the impact of the systemic risk is even more important and can lead to major losses during a crisis. Because of this, the insurer surveils and manages policies almost...

We consider the problem of the global minimization of a function observed with noise. This problem occurs for example when the objective function is estimated through stochastic simulations. We propose an original method for iteratively partitioning the search domain when this area is a nite...

This paper investigates the robustness of the Solvency Capital Requirement (SCR) when a log-normal reference model is slightly disturbed by the heaviness of its tail distribution. It is shown that situations with "almost" lognormal data and a rather important variation between the "disturbed"...

Cette étude présente une mesure et une interprétation de l'hétérogénéité dans la mortalité en Afrique subsaharienne francophone. Ce travail est effectué d'une part au niveau de la population générale, et d'autre part au niveau de la population assurée (c'est-à-dire couverte par...

Dans ce papier, nous nous intéressons à la couverture des contrats en unités de compte avec garanties décès. Nous présentons des stratégies de couverture opérationnelles permettant de réduire de façon significative les coûts futurs liés à ce type de contrats. Suivant les...
