Based on unit record data from four household surveys conducted by Statistics New Zealand for the years 1983/1984, 1991/1992, 1995/1996 and 1997/1998, this paper addresses some ethnic dimensions of income inequality among New Zealanders over the period of the surveys. It applies alternative...

The purpose of this paper is to analyse income inequality trends in New Zealand and Sweden from 1983 to 1997, a period when both New Zealand and Sweden implemented economic reforms that transformed their respective welfare systems. The results do not suggest that the more extensive reform...

Measures of income inequality based on current income are well known to overstate lifetime income inequality for two reasons: intracohort mobility and the shape of the age-earnings profile. Utilizing the concept of age equivalence scales along with varying assumptions concerning the extent of...

This paper proposes a method of estimating total expenditure elasticities based on the implicit Engel equations derived from the Lorenz curve of total expenditure and concentration curves of commodity-specific expenditures. The proposed procedure is computationally easy to implement and produces...

This paper proposes a new method of explaining the temporal change in economic inequality in terms of changes in the sources of income. The method is based on the decomposition of the Gini coefficient by source of income. Using this method, the paper also examines changes of the sources of...
