Abstract

We consider the properties of two monetary policy rules (monetary targeting, Taylor-type interest rate rule) in an intertemporal equilibrium model with capital accumulation and two outside assets (government bonds, fiat money). The paper shows that the long-run behaviour of the economy depends critically on whether under the monetary-fiscal regime the steady-state real interest rate is independent of inflation. If this is the case, there exists in our model a unique steady state with stable adjustment dynamics under either monetary policy rule. By contrast, if superneutrality fails, dynamics under the interest rate rule may suffer from global indeterminacy arising from multiple steady states which do not necessarily differ in terms of the 'activeness' of the interest rate feedback on inflation. This is ruled out under monetary targeting.
