Forward Looking

SummaryThis paper evaluates the performance of optimal simple policy rules in the presence of news shocks. It is shown that the inclusion of forward-looking elements enhances the performance of simple optimized interest rate rules when agents learn about future disturbances in advance. We provide a rationale for this result by demonstrating that, if shocks are news shocks, the optimal unrestricted control rule under commitment contains as a basic principle a forward-looking element.

Forward Looking

This paper develops a general equilibrium model with a banking system and a reserves market and shows that (i) the macroeconomic stabilizing properties of the nominal interest rate rules change quite substantially when we move from a model without a banking system to one with a banking system and a reserves market; (ii) the interplay between fiscal and monetary policies, in particular inflation-indexed versus non-indexed bonds, is crucial in determining the macroeconomic stabilizing properties of monetary rules; (iii) active rules and passive rules perform equally in regard to their macroeconomic stabilizing properties; (iv) continuous- and discrete-time specifications deliver the same/different (in)determinacy results for both the labor-only model and the endogenous-capital model under forward-looking/current-looking rules; (v) the inclusion of physical investment narrows the indeterminacy region under forward-looking rules; and (vi) current-looking rules make equilibrium determinacy impossible for both the labor-only economy and the endogenous-capital economy. Economic intuitions are provided.

The Impact

This paper is critical of the conceptual foundations and methodology adopted by Smithin (2020) in his exploration of the impact of different interest-rate policy rules on inflation. His modelling framework is too narrow to adequately discriminate between different interest-rate rules in terms of their broader macroeconomic impacts.
