In this paper we investigate the problem of selecting an optimal horizon for inflation targeting in the United Kingdom. Since there are two key ways of thinking about an optimal horizon, we look at optimal horizons for both of these interpretations. In addition, to see whether our results are...

This paper analyzes the central bank’s optimal objective function in a small open economy model allowing for incomplete exchange rate pass-through. The results indicate that there are welfare gains from different types of monetary policy inertia. The welfare improvements of exchange rate...

The central bank's optimal reaction to foreign and domestic shocks is analyzed in an inflation targeting model allowing for incomplete exchange rate pass-through. Limited pass-through is incorporated through nominal rigidities in an aggregate supply-aggregate demand model derived from some...

A central bank pursuing the policy of inflation targeting aims to keep inflation as close as possible to a pre-announced value. But which 'inflation' should this be? Quarterly, annual, biennial? In theoretical models it is typically inflation during one period. We analyze how changing the period...

What are the implications of targeting different measures of inflation? We extend a basic theoretical framework of optimal monetary policy under inflation targeting to include several components of CPI inflation ratio, and analyze the implications of using different measures of inflation as...

This paper derives closed-form expressions for optimal monetary policy rules when the central bank can influence inflation directly with a one-period lag as well as a two-period lagged effect via the output gap. It turns out that even a modest one-period inflation effect from monetary policy...
