Les pays d'Afrique subsaharienne ont à scolariser un nombre croissant d'enfants, dans un contexte d'approfondissement de la pauvreté. Si les taux de scolarisation sont plus faibles en milieu rural, les villes connaissent également de fortes difficultés. Cet article analyse, pour Conakry,...

This paper shows that some policy features are crucial to explain the decision of the policyholder to surrender her contract. We point it out by applying two segmentation models to a life insurance portfolio: the Logistic Regression model and the Classification And Regression Trees model....

In this paper we raise the matter of considering a stochastic modeling of the surrender rate instead of the classical S-shaped deterministic curve (in function of the spread), still used in almost all insurance companies. A stochastic model in which surrenders are conditionally independent with...

We present a new model of loss processes in insurance. The process is a couple $(N, \, L)$ where $N$ is a univariate Markov-modulated Poisson process (MMPP) and $L$ is a multivariate loss process whose behaviour is driven by $N$. We prove the strong consistency of the maximum likelihood...

Cette note correspond à la mise en ordre d'un ensemble d'informations sur la situation présente des transports à Cuba. Avec l'introduction de la bicyclette comme mode de transport quotidien, le pays connaît non seulement une mutation très importante de son système de transport urbain mais...

For operational purposes, in Enterprise Risk Management or in insurance for example, it may be important to estimate remote (but not extreme) quantiles of some function ƒ of some random vector. The call to ƒ may be time- and resource-consuming so that one aims at reducing as much as possible...

En jetant un regard sur les écrits qui concernent le thème de la ville international, on aperçoit trois séries d'interrogation qui se complètent et suggèrent une progression très classique, depuis une compréhension élémentaire des choses jusqu'à des prescriptions de politiques...

The purpose of this paper is to point out that an asymptotic rule "A+B/u" for the ultimate ruin probability applies to a wide class of dependent risk models, in discrete and continuous time. Dependence is incorporated through a mixing approach among claim amounts or claim inter-arrival times,...

En matière d'offre de santé en Afrique subsaharienne, les villes apparaissent mieux loties que les villages; aussi, les disparités d'accessibilité aux lieux de soins ont-elles été peu étudiées à l'échelle intra-urbaine. Dans quelle mesure, en contexte de pauvreté, l'accès des...

This paper studies a new risk measure derived from the expected area in red introduced in Loisel (2005). Specifically, we derive various properties of a risk measure defined as the smallest initial capital needed to ensure that the expected time-integrated negative part of the risk process on a...
