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...

The 2002 Policy Targets Agreement (PTA) between the Reserve Bank of New Zealand and the government asks the Reserve Bank to target inflation "over the medium term" rather than over an annual target. This medium term objective shifts inflation targeting towards a "halfway-house" between inflation...

This paper uses wavelets to develop a core inflation measure for inflation targeting central banks. The analysis is applied to the case of New Zealand – the country with the longest history of explicit inflation targeting. We compare the performance of our proposed measure against some popular...

This paper tests the standard quadratic approximation to central bank preferences on data from Australia and New Zealand, two of the earliest explicit inflation targeting countries. The standard linear-quadratic monetary policy model assumes central bank preferences over key macroeconomic...

Counterfactual experiments with the Reserve Bank of New Zealand's core model provide some insight into the implications for New Zealand's economic performance over the 1990s, had it credibly fixed its currency to the Australian dollar. If New Zealand had faced the relatively more stimulatory...

I develop a new estimate of core inflation for New Zealand and Australia based on a dynamic factor model. By using an over-identification restriction, the factors of the model are classified as tradable and nontradable factors. This innovation allows us to examine the relative contributions of...

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 introduces a new indicator of core inflation for New Zealand, estimated using a dynamic factor model and disaggregate price data. Using disaggregate price data we can directly compare the predictive performance of our core indicator with a wide range of other ‘core inflation’...

In this paper, measures of the uncertainty surrounding estimates of New Zealand's potential output are used to consider whether the output gap is a useful concept for the monetary authority to base policy actions on. The analysis relies on stochastic simulations of the Reserve Bank of New...

This paper reviews the concept of core inflation, focusing on the alternative interpretations of core inflation as the persistent or generalised element of inflation. The role of a core inflation measure in policy formulation, communication and accountability is also discussed. The paper also...
