Ce chapitre présente le domaine professionnel et la prise en compte des risques organisationnels, les résultats de recherche en risques organisationnels et le modèle d'identification des risques organisationnels à partir de la coordination.

We study an optimal investment problem under contagion risk in a financial model subject to multiple jumps and defaults. The global market information is formulated as progressive enlargement of a default-free Brownian filtration, and the dependence of default times is modelled by a conditional...

Purpose of the paper: Risk orientated disclosure is a focal issue of corporate communication. Many provisions have been implemented in the USA and in Europe to promote transparency about risks faced by companies, especially by quoted ones. The increase of mandatory risk reporting applying to...

The standard literature on the value of life relies on Yaari’s (1965) model, which includes an implicit assumption of risk neutrality with respect to life duration. To overpass this limitation, we extend the theory to a simple variety of nonadditively separable preferences. The enlargement we...

Recently, the concept of real options had raised in popularity among scholars. Although, real options allow to analyze measure and value uncertainty which are critical steps in decision making, real options are scarcely used in practice. The complexity of the concept is one of the main reasons...

In this article the authors examine the motivation behind the formation of risk pools. They do so by using as suitable study data survey information collected among the rural poor of the Philippines. They discuss the possibility that network formation comes as the result of an attempt to...

This paper analyses the qualitative properties of optimal contracts when agents have multiple priors and are uncertainty averse in an infinite state space framework. The case of the epsilon-contamination of a given prior, a basic tool in robustness theory is fully developped. It is shown that if...

Sorting models consist in assigning alternatives evaluated on several criteria to ordered categories. To implement such models it is necessary to set the values of the preference parameters used in the model. Rather than fixing the values of these parameters directly, a usual approach is to...

This paper is based on a randomised social experiment conducted in order to understand the low take-up rate of a Complementary health-insurance voucher program for the poorest in France (the Aide Complémentaire Santé: ACS). We explore two of the main hypotheses put forward to explain low...
