Money In Monetary Policy Design: Monetary Cross-Checking In The New-Keynesian Model

In the New-Keynesian model, optimal interest rate policy under uncertainty is formulated without reference to monetary aggregates as long as certain standard assumptions on the distributions of unobservable are satisfied. The model has been criticized for failing to explain common trends in money growth and inflation, and that therefore money should be used as a cross-check in policy formulation (see Lucas (2007)). The authors show that the New-Keynesian model can explain such trends if one allow for the possibility of persistent central bank misperceptions. Such misperceptions motivate the search for policies that include additional robustness checks. In earlier work, they proposed an interest rate rule that is near-optimal in normal times but includes a cross-check with monetary information.
