Understanding New Zealand s Changing Income Distribution 1983 98:A Semiparametric Analysis
AbstractThis paper analyses changes in the distribution of equivalised gross household income and income inequality in New Zealand between 1983 and 1998. We analyse the distributional effects of changes in household structure, National Superannuation (old age pension), household socio- demographic attributes and employment outcomes, and in the economic returns to such attributes and employment outcomes, using a semiparametric kernel density approach, and assess the impact of these factors on alternative summary measures of inequality over the period. We find that changes in household structure and in the socio-demographic characteristics of households are the main factors contributing to the rise in inequality, while the large changes in the employment outcomes had a more modest impact, and there is little evidence of systematic effects of changes in the economic returns. The results are qualitatively robust to a variety of equivalisation, income, and weighting measures.
