Inequality measures are often used to summarise information about empirical income distributions. However , the resulting picture of the distribution and of the changes in the distribution can be severely distorted if the data are contaminated. The nature of this distortion will in general...

The tax-payer-as-gambler (TAG) model of tax non-compliance is the classic vehicle for providing some simple insights. Under fairly general conditions this model supports the following four propositions: (1) if the rate of return to evasion is positive everyone evades tax; (2) people with higher...

Instead of Inequality analysis sometimes neglects the problem of allowing differences in people's non-income characteristics in the comparison of income distribution, I would say, At the heart of any distributional analysis there is the problem of allowing for differences in people's non-income...

Orderings of income distribution in terms of inequality should be closely related to orderings in terms of risk. Using a novel mult-country questgionnaire experiment we examine the basis for this claim in terms of respondents' distributional perceptions. We show that in terms of both inequality...

Lorenz curves and second-order dominance criteria are known to be sensitive to data contamination in the right tail of the distribution. We propose two ways of dealing with the problem: (1) Estimate Lorenz curves using parametric models for income distributions, and (2) Combine empirical...

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...
