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 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...

The economic analysis of income distribution and related topics makes extensive use of dominance criteria to draw inferences about welfare comparisons. However it is possible that - just as some inequality statistics can be very sensitive to extreme values - conclusions drawn from empirical...

What are the principal issues on which research on income distributionand inequality focus? How might that focus shift in the immediate future?Prepared for the The Elgar Handbook of Socio-Economics.

Inequality comparisons between countries and over time should take into account problems of data imperfection. We examine the contrasting experience of the UK and spain during the 1980s in terms of the distribution of disposable income. We consider whether the apparent divergence of inequality...
