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.
