In so doing we bring together two important but hitherto largely unrelated areas of the forecasting literature in economics, density forecasting and forecast...

This paper proposes and analyses the Kullback-Leibler information criterion (KLIC) as a unified statistical tool to evaluate, compare and combine density forecasts. Use of the KLIC is particularly attractive, as well as operationally convenient, given its equivalence with the widely used...
