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...

The nature of expectations matters when conducting monetary policy. Models with a learning process can exhibit very different properties from models with other types of expectations rules. This paper draws on the work of Orphanides and Williams (2002), extending it to allow for the possibility...

Simple rules for guiding monetary policy actions have been shown to achieve policy objectives effectively. In many of these simple rules, policy prescriptions depend on the economy's level of potential output. However, potential output is unobservable and is estimated with uncertainty. We...

Some observers have worried that under or over-estimating the output gap may unnecessarily induce tightening or loosening of monetary conditions, causing real fluctuations. To investigate the relationship between the output gap and inflation, we examine models of inflation that do and do not use...

This paper develops a stochastically-based method of measuring core inflation, extending earlier research by Bryan and Cecchetti (1993) and Roger (1995).

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...

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...

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...
