The ability of financial frictions to amplify the output response of monetary policy, as in the financial accelerator model of Bernanke et al (1999), is analysed for a wider class of policy rules where the policy interest rate responds to both inflation and the output gap. When policy makers...

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...

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, stochastic simulations of the Reserve Bank of New Zealand's new macroeconomic model, FPS, are used to examine the issue of which price index monetary policy should stabilise in a small open economy. Under the class of policy rules considered, targeting a measure of domestic...

Real Business Cycle (RBC) and Dynamic Stochastic General Equilibrium (DSGE) methods have become essential components of the macroeconomist’s toolkit. This literature review stresses recently developed (often Bayesian) techniques for computation and inference, providing a supplement to the...

This paper analyzes the transmission mechanism of banking sector shocks in an international real business cycle model with heterogeneous bank sizes. We examine to what extent the financial exposure of the banking sector affects the transmission of foreign banking sector shocks. In our model, the...

We compute classical real GDP business cycles and growth cycles, contrast classical recessions with 'technical' recessions, and assess the sensitivity of our peaks and troughs to data revisions. Calling a technical recession after two successive quarters of negative growth can provide...

This paper investigates labour market dynamics in New Zealand by estimating a structural small open economy model enriched with standard search and matching frictions in the labour market. We show that the model its the business cycle features of key macroeconomic variables reasonably well and...

We estimate changes in the volatility of firm-level sales, earnings and employment growth of US firms. Our method differs from existing measures for firm-level sales and employment volatility in that it not only captures longer-run changes in volatility, but also measures cyclical changes in...
