This paper defines an efficient rule for monetary policy as one that minimises a weighted sum of output variance and inflation variance. It derives several results about the efficiency of alternative rules in a simple macroeconomic model. First, efficient rules can be expressed as "Taylor rules"...

Recently it has been argued that a monetary policy of nominal income targeting would result in dynamically unstable processes for output and inflation. That result holds in a theoretical model that includes backward-looking IS and Phillips curve relations, but these are rather special and...

Recent research has found evidence of increasing co-movement in CPI inflation rates across industrialised countries. This paper considers whether this increased international co-movement in inflation rates can be attributed to greater global integration of product markets. To examine this...

New evidence from a large survey of over 5300 firms provides insight into price-setting behaviour in New Zealand. There is considerable heterogeneity in behaviour both between and within sectors, and marked asymmetry in the responses to shocks. The median number of prices reviews is twice per...

We show that internationalised production, modelled as trade in intermediate goods, brings the dynamics of a small open economy closer to that observed in the data. We build a stylized new-Keynesian small open economy model and we show that when production is internationalised, movements of...

We conduct a high frequency event analysis to estimate the effects of monetary policy surprises, data surprises, and central bank verbal statements on the New Zealand-US dollar and the New Zealand-Australian dollar exchange rates. We find data surprises and monetary policy surprises have...

We estimate underlying macroeconomic policy objectives of three of the earliest explicit inflation targeters - Australia, Canada and New Zealand - within the context of a small open economy DSGE model. We assume central banks set policy optimally, such that we can reverse engineer policy...

This paper examines stabilisation bias - the difference between the inferior macroeconomic outcomes attained with discretionary monetary policy relative to the ideal that could be attained with commitment policy. The paper works within the linear-quadratic framework and represents the monetary...

New Zealand data show that the inflation-output relationship is asymmetric. This asymmetry implies that positive demand shocks tend to increase inflation by more than negative demand shocks of similar magnitudes reduce it. An important implication of this asymmetry is that a monetary authority...

This paper quantifies the costs of mitigating exchange rate volatility within the context of a flexible inflation targeting central bank. Within a standard linearquadratic formulation of inflation targeting, we append a term that penalises deviations in the exchange rate to the central bank’s...
