The subjective forecasts used in decision analysis should, in principle, synthesize all available evidence about the subject in analysis. In this manner, when part of the evidence consists of a variety of forecasting models or expert opinions, Decision Theory requires the decision maker to formulate a combination of these predictors. This work takes into account the Bayesian methodologies outperformance and quasi-Bayes, as well as the classical model of optimal combination, all applied to the linear combination of petroleum price forecasts, generated by experts from Petrobras-the Brazilian oil company-for several international markets. It presents a theoretical description of the methodologies followed by a comparative analysis between performances of the best experts' forecasts and combinations. The performances and features of these combinations are also compared.
