Poverty and inequality are often estimated from grouped data as complete household surveys are neither always available to researchers nor easy to analyze. In this study we assess the performance of functional forms proposed by Kakwani (1980a) and Villasenor and Arnold(1989) to estimate the...

This article conceives poverty in terms of the consumption of essential food, makes use of a new deprivation (or poverty) function, and examines the effects of changes in the mean and the variance of the income distribution on poverty, assuming a log-normal income distribution. The presence of a...

This article examines inequality and poverty among older people in Japan. It compares Japan with that of a sample of other OECD countries. Provisions within the social insurance system that enable old-age pensioners to work and draw incomes from labor explain some of the inequality and poverty...

Accounting for environmental damage is relevant to how one measures the extent and severity of inequality and poverty, and the question of ecological distribution - how the costs associated with environmental damage are distributed across the population - is critical. Following Khan’s (1997)...

The Income Reference Period (IRP), the measurement period of income, differs across micro-economic databases of household or individual incomes; typically it is a year, a quarter (of a year) or a month. The length of the IRP affects the shape of the income distribution and derived distributional...

Inequality measurement involves explicit or implicit value judgements. The subjective approach to inequality measurement is a relatively new and fast-developing area which focueses direct attention on these judgements. It is 'subjective' in the sense that it takes accounts of peoples' views on...

Should raising the growth rate of GDP per capita be a policy goal of governments in general, and of the British government in particular? Many people would say no, for the following reasons: 1) GDP is hopelessly flawed as a measure of welfare; 2) Growing GDP is pointless since most people don’t...

Theil’s information-theoretic approach to the measurement of inequality (Theil 1967) is set in the context of subsequent developments over recent decades. It is shown that Theil’s initial insight leads naturally to a very general class of inequality measures. It is thus closely related to a...

Starting from the axiomatisation of polarisation contained in Esteban and Ray (1994) and Chakravarty and Majumdar (2001) we investigate whether people's perceptions of income polarisation is consistent with the key axioms. This is carried out using a questionnaire-experimental approach that...

The techniques of simple random sampling are seldom appropriate in the empirical analysis of income distributions. Various types of weighting schemes are usually required either from the point of view of welfare-economic considerations (the mapping of household/family distributions into...
