This paper examines the choice of a monetary-policy rule in a simple macroeconomic model. In a closed economy, the optimal policy is a output and inflation. In an open economy, the optimal rule changes in two ways. First, the policy instrument is a Conditions Index the exchange rate. Second, on...

We study how changes in the value of the steady-state real interest rate affect the optimal inflation target, both in the U.S. and the euro area, using an estimated New Keynesian DSGE model that incorporates the zero (or effective) lower bound on the nominal interest rate. We find that this...

This paper deals with the relationship between inflation targeting and exchange rates. I address three specific issues: first, I analyze the effectiveness of nominal exchange rates as shock absorbers in countries with inflation targeting. This issue is closely related to the magnitude of the...

Forward guidance about future policy settings, in the form of a published policy-rate path, has for many years been a natural part of normal monetary policy for several central banks, including the Reserve Bank of New Zealand and the Swedish Riksbank. More recently, the Federal Reserve has...

We assess the power of forward guidance—promises about future interest rates—as a monetary tool in a liquidity trap using a quantitative incomplete-markets model. Our results suggest the effects of forward guidance are negligible. A commitment to keep future nominal interest rates low for a...

The relationship between interest rates and exchange rates is puzzling and poorly understood. But under some standard assumptions, interest rates can be adjusted to smooth real exchange rate movements at the possible price of increased volatility in other variables. In New Zealand, estimates...

Inflation targeting is a monetary-policy strategy that is characterized by an announced numerical inflation target, an implementation of monetary policy that gives a major role to an inflation forecast and has been called forecast targeting, and a high degree of transparency and accountability....

In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

In recent years, large fluctuations in world food prices have renewed interest in the question of how monetary policy in small open economies should react to imported price shocks. We address this issue in an open economy setting similar to previous ones except that food plays a distinctive role...
