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...

This paper demonstrates the proper use of the disaggregation of the Gini coefficient by factor components by deriving a formula of the elasticity of the Gini coefficient with respect to specific income components. The method is then applied to Australian household expenditure survey data to find...

This paper develops an economic measure of relative deprivation and explores its relationship to envy and economic inequality. It is demonstrated that, while the concept of envy is virtually identical with that of relative deprivation, economic inequality, although a related concept, and a...

A new procedure is proposed for estimating Engel elasticities using the Lorenz/concentration curve approach. The method is an extension of works by N. C. Kakwani and S. Yitzhaki. However, the proposed procedure is more flexible in permitting the estimation of standard errors through the usual...

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...
