Is there a trade-off between people's preference for income equality and income mobility? Testing for the existence of such a trade-off is difficult because mobility is a multifaceted concept. We analyse results from a questionnaire experiment based on simple precise concepts of income...

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...

Firms are usually better informed than tax authorities about market conditions and the potential profits of competitors. They may try to exploit this situation by underreporting their own taxable profits. The tax authority could offset firms' informational advantage by adopting "smarter" audit...

We provide a parsimonious axiomatisation of the complete class of absolute nequalityindices. Our approach uses only a weak form of decomposability and does not require a priori that the measures be differentiable.

We show how classic source-decomposition and subgroup-decomposition methodscan be reconciled with regression methodology used in the recent literature. We alsohighlight some pitfalls that arise from uncritical use of the regression approach. TheLIS database is used to compare the approaches...

Specific functional forms are often used in economic models of distributions; goodness-of-fit measures are used to assess whether a functional form is appropriate in the light of real-world data. Standard approaches use a distance criterion based on the EDF, an aggregation of differences in...

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...

We examine the specification and interpretation of the transfer principle in analysing income distributions. The early work by Pigou and Dalton on this topic left open the possibility of a variety of specifications and interpretation of the principle. The modern development of the theory since...
