| Résumé anglais |
This article demonstrates that the concept of uncertainty, as understood by Keynes and Knight, need not entail a radical indeterminacy in economic phenomena. On the contrary, uncertainty can be correlated to specific forms of behaviour that can be formalised. It is possible to distinguish between financial relations involving risk, on the one hand, and uncertainty, on the other — where traditional bargaining corresponds to the former, and uncertainty, to the latter. In order to establish these points, we present a precise and operational formalisation of uncertainty. The hypothesis of a mimetic or imitative logic of interaction is used to specify behabioural patterns within situations of uncertainty. The result is a model enabling us to eliminate some of the vagueness traditionally linked to the notion of uncertainty. Source : Éditeur (via Persée) |
