Aggregation of not necessarily independent opinions
We consider an aggregation scheme of opinions expressed through different probability distributions or multiple priors decision model. The decision-maker adopts entropy maximization as a measure of risk diversification and a rational form of prudence for valuing uncertain outcomes. We show a new aggregation rule formalization based on the idea that the decision-maker has a more reliable set of outcomes called ordinary and two fat tails that include more ambiguous and extreme events.
