A structural VAR model of the New Zealand business cycle

New Zealand Treasury Working Paper 02/26

Published: December 2002

Authors: Robert A Buckle, Kunhong Kim, Heather Kirkham, Nathan McLellan and Jared Sharma

Abstract

This paper develops a new open economy structural VAR model of the New Zealand economy. The model adopts techniques introduced by Cushman and Zha (1997) and Dungey and Pagan (2000) to identify international and domestic shocks and dynamic responses to these shocks in a small open economy. The international variables are block exogenous and the model includes restrictions on contemporaneous and lagged variables. Novel features include the introduction of an expanded set of domestic financial variables not captured in previous New Zealand VAR models, the use of a forward looking Taylor Rule to identify monetary policy, and the introduction of a climate variable to capture the impact of climatic conditions on the business cycle. Key results to emerge are the significant influence of international variables on the New Zealand business cycle, the importance of separately identifying import price and export price shocks, and the significant influence of climate.

The model developed in this paper arose from the need within Treasury to better understand the forces that contribute to fluctuations in New Zealand’s GDP and to provide a basis for applying structural VAR modelling to other policy related issues.
