This paper argues that the adoption of an inflation target reduces the persistence of inflation.We develop the theoretical literature on inflation persistence by introducing a Taylor rule for monetary policy into a model of persistence and showing that inflation targets reduce inflation...

This paper argues that the parameters of monetary policy rules affect the persistence of inflation and output. Persistence is lower if monetary policy emphasises the price level or if there is an inflation target. A greater emphasis on output increases persistence. There is a simple New...

This paper analyses a model of non-linear exchange rate adjustment that extends the literature by allowing asymmetric responses to over- and under-valuations. Applying the model to Greece and Turkey, we find that adjustment is asymmetric and that exchange rates depend on the sign as well as the...

This paper analyses the impact of uncertainty about the true state of the economy on monetary policy rules in the US since the early 1980s. Extending the Taylor rule to allow for this type of uncertainty, we find evidence that the predictions of the theoretical literature on responses to...

We argue that an increase in aggregate demand can lead to a reduction in the interest rate.This apparently perverse optimal response of interest rates can occur when the Phillips curve is non-linear. In that case, an increase in aggregate demand tends to increase inflation and output but also to...

We propose a simply yet flexible framework for the analysis of optimal monetary policy rules that produces the type of non-linear responses derived in the literature as special cases. Perhaps more importantly, our framework suggests a richer set of nonlinear responses than have been considered...

We estimate a flexible model of the behaviour of UK monetary policymakers in the era of inflation targeting based on a new representation of policymaker’s preferences. This enables us to address a range of issues that are beyond the scope of the existing literature. We find a complex...
