Partage des risques et création de valeur ajoutée
Abstract[fre] Partage des risques et crÃ©ation de valeur ajoutÃ©e. . Les notions de prix d'achat et de prix de vente d'une loterie sont prÃ©sentÃ©es pour dÃ©finir les conditions d'un transfert de risque entre deux agents.. L'Ã©change optimal consiste, dans cet article, Ã maximiser la valeur ajoutÃ©e crÃ©Ã©e par le transfert. Nous montrons sous des hypothÃ¨ses concernant la forme de l'Ã©change (transfert proportionnel) qu'il existe une solution unique Ã ce problÃ¨me d'optimisation.. Nous prÃ©sentons plusieurs exemples d'application permettant de prÃ©ciser l'importance de la valeur ajoutÃ©e crÃ©Ã©e par le transfert de risque. [eng] Risk sharing and value-added creation . . Asking and bid priees of a lottery are used to analyze the exchange of risks between two agents. The optimum trade is defined by the maximization of the value-added created by the transfer. As is usual, this value-added is measured by the difference between asking and bid priees. We prove that under a proportional transfer, the maximization problem has a unique solution. Several examples are provided, which illustrate the value-added created by the exchange.
