This paper addresses whether non-uniqueness of equilibrium is a substantive problem for the analysis of fiscal policy in New-Keynesian (NK) models at the zero lower bound (ZLB). There would be a substantive problem if there were no compelling way to select among different equilibria that give...

This paper studies how the monetary policy regime affects the relative importance of nominal exchange rates and inflation rates in shaping the response of real exchange rates to shocks. We document two facts about countries with floating exchange rates where monetary policy controls inflation...

In the history of monetary theory and monetary policy, there can be little doubt that the 1980’s are seen as a watershed. Following a disastrous decade of inflation and recession in the 1970’s, the monetarist ideas of Milton Friedman are largely seen to have triumphed then over the older...

This paper documents two facts about countries with floating exchange rates where monetary policy controls inflation using a short-term interest rate. First, the current real exchange rate predicts future changes in the nominal exchange rate at horizons greater than two years both in sample and...

We analyze the framework for monetary policy in view of the effective lower bound (ELB). We find that the ELB is likely to bind in most future recessions and propose some ways that theoretical models imply that the framework could be strengthened. We also discuss ways that commitment strategies,...
