When families reform there are implications for the income distribution through a number of economic mechanisms: income sharing, changes in household need, reweighting the distribution. These changes are distinct from those that generate changes in factor income or transfers and may affect...

We examine the sensitivity of estimates and inequality indices to extreme values, in the sense of their robustness properties and of their statistical performance. We establish that these measures are very sensitive to the properties of the income distribution. Estimation and inference can be...

We develop two simple measures of how much inequality is explained by individual population characteristics or groups of characteristics, analogous to R2 in regression analysis. We investigate the measures' empirical implementation using several alternative theoretically consistent approaches to...

Using a simple axiomatic structure we characterise two classes ofinequality indices - absolute and relative - that take into account "envy"in the income distribution. The concept of envy incorporated hereconcerns the distance of each person's income from his or herimmediately richer neighbour....

The 'prediction approach' proposed by Dearden, Machin and Reed (DMR) consists in (1) regressing the observed incomes of the child and parent families on separate sets of predetermined variables, and (2) regressing the child's predicted income on that of the parents. Conceptually, this estimator...

In this paper we examine the concept of "vulnerability" within the context of incomemobility of the poor. We test for the dynamics of vulnerable households in the UKusing Waves 1 - 12 of the British Household Panel Study and find that, of threedifferent types of risks that we test for,...

Temkin (1986,1993) sets out a philosophical basis for the analysis of income inequality that provides an important alternative to the mainstream welfarist approach. We show that the Temkin principles can be characterised by a parsimonious axiomatic structure and we use this structure to derive a...

Drawing on recent work concerning the statistical robustness of inequality statistics we examine the sensitivity of poverty indices to data contamination using the concept of the influence function. We show that poverty and inequality indices have fundamentally different robustness properties,...

We examine the evidence on rank and income mobility in China during the decades immediately preceding and immediately following the millennium using panel data from the China Health and Nutrition Survey. We show that rank mobility changed markedly over the period: in this respect China is...

We address a puzzle in welfare economics - the possibility that rational people may be simultaneously against two apparently con‡icting forms of "tyranny." In fact the two types of tyranny can be reconciled but at the possible cost of con‡ict with other standard welfare principles. We...
