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 argues that UK monetary policymakers did not respond to the inflation rate during most of the "Great Moderation" that ran from the early 1990s to the mid-2000s. We derive a generalisation of the New Keynesian Phillips curve in which inflation is a non-linear function of the output gap...

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...

The optimal monetary policy response to an increase in aggregate demand may be to reduce the interest rate. This apparently perverse response of interest rates can occur when the Phillips curve is non-linear.
