Aggregation of coherent experts opinion: a tractable extreme-outcomes consistent rule


  • Marcello Basili


  • Alain Chateauneuf



The paper defines a consensus distribution with respect to experts’ opinions by a multiple quantile utility model. The paper points out that the Steiner Point is the representative consensus probability. The new rule of experts’ opinions aggregation, that can be evaluated by the Shapley value in a simple way, is prudential and coherent.
