    Abstract

    A short overview of how risk is conceived by practitioners reveals nine features of risk while theoreticians worry more about the way of solving the discrepancies between the predictions of the expected utility paradigm and the actual behaviour of people. Anyway, quickly expanding new theories of risk do not encompass enough components of risk. The last section of this paper is devoted to the new bipolar theory of risk proposed by the author, where risk is a vector and could benefit from a multicriterion approach. Un survol limité du concept du risque chez les praticiens nous révèle neuf caractéristiques du risque, tandis que les théoriciens s’intéressent surtout à la réduction des écarts entre les prédictions du paradigme de l’espérance d’utilité et le comportement des décideurs. Le foisonnement des nouvelles théories du risque n’incorporent pourtant pas assez de composantes du risque. Enfin, la dernière section de ce papier envisage une nouvelle théorie du risque : dans cette théorie bipolaire, le risque vectoriel peut bénéficier d’une approche multicritère.
