The purpose of the paper is to use the age of claims in the prediction of risks. A dynamic random effects model on longitudinal count data is presented...

This paper proposes bonus-malus systems for fleets of vehicles, by using the individual characteristics of both the vehicles and the carriers. Bonus-malus coefficients are computed from the history of claims or from the history of safety offences of the carriers and the drivers...

This paper provides bonus-malus systems which rest on different types ofclaims. Consistent estimators are given for some moments of the mixingdistribution of a multi equation Poisson model with random effects...

This paper presents a case study of a portfolio of individual long-term insurance contracts sold by a Spanish mutual company. We describe the risk levels, the rating structure and the implied cross-subsidies on a portfolio of policies providing health, life and long-term care insurance. We show...

This paper presents statistical models which lead to experience rating in insurance. Serial correlation for risk variables can receive endogeneous or exogeneous explanations. The interpretation retained by actuarial models is exogeneous and reflects the positive contagion usually observed for...

Road safety policies and automobile insurance contracts often use incentive mechanisms based on traffic violations and accidents to promote safe driving. Can these mechanisms improve road safety efficiently? Do they reduce asymmetric information between drivers and insurers and regulators? In...

Road safety policies often use incentive mechanisms based on traffic violations to promote safe driving. Examples of mechanisms are fines, experience rating and point-record driving licenses. We analyse the effectiveness of these mechanisms in promoting safe driving. We derive their theoretical...

A captive is an insurance or reinsurance company established by a parent group to finance its own risks. Captives mix internal risk pooling between the business units of the parent group and risk transfer toward the reinsurance market. We analyze captives from an optimal insurance contract...

This paper analyzes the rationale of long-term care insurance purchasing, from a statistical analysis of insurance data and a life cycle model. We make a short survey of the pros and cons of LTC insurance purchase. Then risk distributions in the occurrence and duration dimension are estimated on...

Les biais de sélection sont créés par des disparités entre le domaine d'estimation d'un modèle statistique et son domaine d'application. C'est le cas pour les modèles évaluant le risque de fraude, qui sont estimés sur les seuls sinistres audités mais appliqués sur tous les sinistres...
