THE COMPOSITION AND CONSTRUCTION OF MONETARY AGGREGATES

An economic monetary aggregate is composed from a set of monetary goods that are at least weakly separable from other goods in the optimizing agent's utility function. We construct such an aggregate using a Divisia index number. We demonstrate that through the middle of the 1980s forecasts of the inflation rate based on our economic monetary aggregate are superior to forecasts based on the simple sum monetary aggregates M1 or M2.
