Du risque à l'incertitude dans les modèles de décisions

Abstract: It is not common for a result in theory, expressed in mathematical terms, to bear upon economic analysis and its applications - specially in insurance and finance - as is the case with the von Neumann-Morgenstern model of decision - making under risk. However this model is dependent upon the existence of a probability distribution to describe the risk facing the decision-maker. In an increasing number of situations challenging the sustainability of development - consequences of climate change, public health issues, etc. - uncertainty doesn't boil down to risk, i.e. uncertainty may not be characterized with a probability distribution. However criteria have recently been found, that generalize the von Neumann-Morgenstern one, for an operational approach of decision-making under uncertainty.
