摘要:

An information framework is proposed for studying uncertainty anddisagreement of economic forecasters. This framework builds upon themixture model of combining density forecasts through a systematic application of the information theory. The framework encompasses the measuresused in the literature and leads to their generalizations. The focal measureis the Jensen–Shannon divergence of the mixture which admits Kullback–Leibler and mutual information representations. Illustrations include exploringthe dynamics of the individual and aggregate uncertainty about the USinflation rate using the survey of professional forecasters (SPF). We showthat the normalized entropy index corrects some of the distortions causedby changes of the design of the SPF over time. Bayesian hierarchical modelsare used to examine the association of the inflation uncertainty with theanticipated inflation and the dispersion of point forecasts.Implementationof the information framework based on the variance and Dirichlet modelfor capturing uncertainty about the probability distribution of the economicvariable are briefly discussed.
