La comparaison des secteurs non lucratifs américain et français commence par un état des lieux en 1995. Les données empiriques strictement comparables sont interprétées par les ideal-types libéral anglo-saxon et partenarial européen de bien-être. Dans un deuxième temps, on analyse...

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...

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...

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,...

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...

In this paper, we formulate a noncooperative game to model a non-life insurance market. The aim is to analyze the e ects of competition between insurers through di erent indicators: the market premium, the solvency level, the market share and the underwriting results. Resulting premium Nash...

The European Union in its widening movement shows five clusters of Third sector organisations with complex bonds and ties with the surrounding societies and national identities In introduction, we compare briefly the Europe's Third sector features to North America's ones (Historical and...

En décembre 2008, le BIT a recommandé d'adjoindre à l'Enquête Emploi un bref questionnaire pour mesurer le travail bénévole. L'article examine en premier lieu les faiblesses méthodologiques des enquêtes sur le bénévolat en France et dans quelques pays anglo-saxons pour montrer la...
