In this paper we systematically evaluate how central banks respond to inflation deviations from target. We present a stylized New Keynesian model in which agents' inflation expectations are sensitive to inflation deviations from target. To (re-)establish credibility, optimal monetary policy...

We develop simple diagrams that can be used by undergraduates to understand interest rate setting by policy-makers. We combine an inflation target, Fisher equation, policy reaction function and short and long run aggregate supply analysis to give a depiction of the policy problem. We illustrate...

“Forecast targeting,” forward-looking monetary policy that uses central-bank judgment to construct optimal policy projections of the target variables and the instrument rate, may perform substantially better than monetary policy that disregards judgment and follows a given instrument rule....

After decades using monetary aggregates as the main instrument of monetary policy and having different varieties of crawling peg exchange rate regimes, Colombia adopted a full-fledged inflation-targeting (IT) regime in 1999, with inflation as the nominal anchor, a floating exchange rate, and the...

I analyze how the introduction of financial frictions can affect the trade-off between output stabilization and inflation stability and whether, in the presence of financial frictions, the optimal outcome can be realized or approached more closely if monetary policy is allowed to react to...

What role does (should) money play in modern central banking? To answer this question, it is necessary to distinguish between the different level playing fields of monetary policy. At the operational level, it is a short-term money market rate which the central bank tries to and can control....

Conventional wisdom says that commitment eliminates the inflationary bias of monetary policy. However, this paper shows that the inflation bias can persist even when the central bank commits. A simple model is presented in which the central bank precommits by setting the policy instrument, and...

We investigate the relative roles of monetary policy and shocks in causing the Great Moderation, using indirect inference where a DSGE model is tested for its ability to mimic a VAR describing the data. A New Keynesian model with a Taylor Rule and one with the Optimal Timeless Rule are both...

This paper assumes that a central bank commits itself to maintaining an inflation target and then asks what measure of the inflation rate the central bank should use if it wants to maximize economic stability. The paper first formalizes this problem and examines its microeconomic foundations. It...
