In this paper, we want to characterize the optimal health insurance contract with adverse selection and moral hazard. We assume that policyholders differ by the permanent health status loss and choose an unobservable preventive effort in order to reduce the probability of illness which is...

This paper investigates the impact of health risk on insurance contract with hazard moral. We use a bi-dimensional utility function (wealth and health status). We prove that the type of health risk influences the equilibrium of insurance market. A full coverage is possible with moral hazard....

An F-cone is a pointed and generating convex cone of a real vector space that is the union of a countable family of finite dimensional polyedral convex cones such that each of which is an extremel subset of the subsequent one. In this paper, we study securities markets with countably many...

Dans un contexte de vieillissement de la population, différents scenarii sont envisagés pour réformer l'organisation et le financement de la prise en charge des personnes âgées dépendantes. La place de la prévoyance individuelle dans le financement de la dépendance est à ce titre...

Insurance coverage for natural disasters remains low in many exposed areas. A limited supply of insurance is commonly identified as a primary causal factor in this low insurance coverage. The French overseas departments provide a rare natural experiment of a well-developed supply of natural...

The European Union is completely redesigning the system of prudential supervision of insurance institutions as part of the Solvency Directive II. During its implementation, the Directive, which can be compared to the Basel II prudential standard, was analysed above all in terms of actuarial...

The new prudential standards, Solvency II, consider the question of controling of insurer and reinsurer’s solvency. In this thesis, we’ve proposed technical solution for solvency capital assessment to keep ruin’s probability under the target of 0.5% aimed by the Solvency II project in...

This article deals with optimal insurance contracts in the framework of imprecise probabilities and adverse selection. Agents differ not only in the objective risk they face but also in the perception of risk. In monopoly, a range of configurations that VNM preferences preclude appears: a...

Private insurance for long-term care is underdeveloped in European countries and in the US. This paper tries to understand why the market is underdevelopped by using a theoretical approach and putting the emphasis on insurance demand. It shows that demand for long term care insurance can be low...
