Inequality and Welfare Evaluation of Heterogeneous Income Distributions

This paper establishes the principles which should govern the welfare and inequality analysis of heterogeneous income distributions. Two basic criteria?the ?equity preference? condition and the ?compensation principle??are shown to be fundamentally incompatible. The paper favours the latter, thereby vindicating the traditional method of dealing with heterogeneous samples. However, inequality and welfare comparisons will usually be well defined only if equivalent incomes are obtained using constant scale factors; and researchers will need to distinguish clearly between inequality of nominal incomes and inequality of living standards. Furthermore, household observations must always be weighted according to family size.income distribution, inequality, living standards, needs

Ungrouping Income Distributions: Synthesising Samples for Inequality and Poverty Analysis

We describe a new method of facilitating inequality and poverty analysis of grouped distributional data by allowing individual income observations to be reconstructed from any feasible grouping pattern. In contrast to earlier methods, our procedure ensures that the characteristics of the synthetic sample exactly match the reported values. The performance of the algorithm is evaluated first by using household survey records to compare true income observations with their synthetic counterparts, then by comparing the true and generated values of the Gini coefficient and other inequality indices. The results indicate that the new technique is capable of reproducing individual data from grouped statistics with a high degree of accuracy.grouped data, income distribution, inequality, poverty

In what ways does gender matter for voting behaviour in GE2017?

In an election characterised by a focus on Brexit, gender-neutral campaigns, and a dominant Conservative Party supported by more men than women, Rosalind Shorrocks explains the ways in which gender may affect vote choice. She writes that although Labour is particularly popular among young women, this is also the demographic most undecided about how to vote

The Liberal Democrats could get an electoral boost from undecideds – especially women

In past elections, undecided women were more likely to vote for the Liberal Democrats than undecided men, and decided male and female voters. In this post, Rosalind Shorrocks asks whether this pattern is likely to be repeated in the election in May

A decomposition analysis of regional poverty in Russia

This paper applies a new decomposition technique to the study of variations in poverty across the regions of Russia. The procedure, which is based on the Shapley value in cooperative game theory, allows the deviation in regional poverty levels from the all- Russia average to be attributed to three proximate sources; mean income per capita, inequality, and local prices. Contrary to expectation, regional poverty variations turn out to be due more to differences in inequality across regions than to differences in real income per capita. However, when real income per capita is split into nominal income and price components, differences in nominal incomes emerge as more important than either inequality or price effects for the majority of regions
