Using the capital stock series recently released by Statistics New Zealand, two approaches have been employed to estimate a production function. The first approach is based on the estimation of a constant elasticity of substitution (CES) production function with a value added form. The second...

This paper documents the structure and key properties of a computable general equilibrium (CGE) model of the New Zealand economy. It is a three-good, small open economy model, which features a well-developed production block. This production block has been estimated as a system using Full...

This paper investigates and compares the dynamic properties of the New Zealand Treasury model (NZTM) and the current version of the Reserve Bank's Forecasting and Policy System model (FPS). The main use of both two models is to produce macroeconomic forecasts. The NZTM model produces forecasts...

This paper estimates the non-increasing inflation rate of unemployment or NAIRU for New Zealand. A NAIRU that varies over time has important implications in considering inflationary pressures. This paper estimates the time-varying NAIRU using a Kalman filter on a reduced form approach and...

The composition of the New Zealand workforce has changed considerably over the past two decades. Qualification levels have risen, labour force participation has trended upwards for women, immigrants have increasingly been sourced from Asia, and the large baby-boom cohort has contributed to an...

The Treasury has been testing the assumptions on the potential growth rate of the New Zealand economy. In this paper, we estimate a small macro model using Bayesian techniques, which allows us to assess the level of uncertainty of the estimates of the output gap. The model is based on the work...

This paper seeks to quantify how the welfare of different types of household changed between 2006/07 and 2009/10; a period which included the 2008/09 recession. We use three measures of household welfare: income, expenditure and the equivalent variation metric. The equivalent variation is a...

This paper has two main aims. First, the poor targeting of a policy of zero-rating food in a goods and services tax (GST) is illustrated in a simple model where the revenue lost from zero-rating food is instead devoted to a universal transfer payment, with a larger effect on progressivity....
