Subjective Evaluation of Composite Econometric Policy Inputs

"Subjective Evaluation of Composite Econometric Policy Inputs," Socio-Economic Planning Sciences, Vol. 20 (1986), 51-55 (with J.L. Ringuest and J.A. Richardson). Studies have suggested that a composite forecast may be preferred to a single forecast. In addition, forecasting objectives are often conflicting. For example, one forecast may have the smallest sum of absolute forecast errors, while another has the smallest maximum absolute error. This paper examines the appropriateness of using multiple objective linear programming to determine weighted linear combinations of forecasts to be used as inputs for policy analysis. An example is presented where the methodology is used to combine the forecasts for several policy variables. The forecasts are selected from large econometric, consensus, and univariate time series models.
