Based on the report “Handicap-Incapacités-Dépendance” of the French “Ministère de la Santé” and on scenarios for the disability of elder persons, the rating, the reserving and the financial balance relative to such a disability porfolio are examined in a prospective approach. The...

The purpose of this paper is to offer customer relationship insights in what is a fast developing new e-commerce development strategy. We examine the potential synergies between digital social networks (DSN) and e-commerce websites, thus bringing e-commerce and DSN websites into the same...

Le potentiel des réseaux sociaux numériques (RSN) reste à démontrer lorsqu'ils sont utilisés conjointement aux sites web marchands. Pour réussir à utiliser les RSN en vue de faire des profits, les organisations de toutes tailles qui pratiquent déjà le commerce électronique doivent...

Private insurance for long-term care is underdeveloped in European countries and in the US. In order to better understand this actual market failure, it is interesting to study the characteristics of insurance demand. This paper uses banking data to estimate the likelihood to buy a long-term...

We present mathematical results allowing one to evaluate the moments of order 1 and 2 of the cedent's share in the framework of reinsurance treaties based on ordered claim sizes. These results consist of closed analytical formulas that do not involve any approximation procedure. This is...

Using classical results on the projective limit of a sequence of subsets, we show the existence of martingale selectors for a multivalued martingale (and supermartingale) with closed values in a separable Banach space X. The existence of L1(X)-bounded or uniformly integrable martingale selectors...

We first establish a general version of the Birkhoff Ergodic Theorem for quasi-integrable extended real-valued random variables without assuming ergodicity. The key argument involves the Poincaré Recurrence Theorem. Our extension of the Birkhoff Ergodic Theorem is also shown to hold for...

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...
