We characterize a firm as a nexus of activities and projects with their associated cashflows. Production and operations activities and real risk management activities distribute cashflows over states of nature and time periods, leading to a transformation possibility frontier similar to a...

A discrete time probabilistic model, for optimal equity allocation and portfolio selection, is formulated so as to apply to (at least) reinsurance. In the context of a company with several portfolios (or subsidiaries), representing both liabilities and assets, it is proved that the model has...

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...

In this paper we consider two particular Canadian defined benefit pension plans to illustrate the importance of adequate mortality forecasting on actuarial liabilities. An employer who sets up an employee defined benefit pension plan promises to periodically pay a certain sum to the participant...

Examining the global reinsurance market for catastrophic losses, we propose a new theory of optimal risk sharing that finds its inspiration in the economic theory of the firm. Our model offers a theoretical foundation for the vertical and horizontal tranching of insurance contracts (also known...

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...

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....

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...
