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

We focus on a relatively neglected area of the tax-compliance literature in economics, the behaviour of firms. We examine the impact of alternative audit rules on receipts from a tax on profits in the context of strategic inter- dependence of firms. In the market firms may compete in terms of...

The potential impact of smart cards is examined in the context of a standard model of direct and indirect taxation. The distinction between the two types of tax is made in terms of the information required to implement them. Electronic cards in general are understood as devices for enriching and...

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...

Starting from the axiomatisation of polarisation contained in Esteban and Ray (1994) and Chakravarty and Majumdar (2001) we investigate wheather paople's perceptions of income polarisation is consistent with the key axioms. This is carried out using a questionnaire-experimental approach that...

Much of the theoretical literature on inequality assumes that the equalisand is a cardinal variable like income or wealth. However, health status is generally measured as a categorical variable expressing a qualitative order. Traditional solutions involve reclassifying the variable by means of...

Building on previous studies on perceptions of inequality, welfare and risk we investigate the structure of individuals' rankings of uncertain prospects in terms of risk and their relationship to individual preferences. We examine three interlinked propositions that are fundamental to the...

Theil’s information-theoretic approach to the measurement of inequality (Theil 1967) is set in the context of subsequent developments over recent decades. It is shown that Theil’s initial insight leads naturally to a very general class of inequality measures. It is thus closely related to a...
