Recent studies attempt to quantify the extent to which income inequality is due to income components, such as earnings, investment income and transfer income. This paper examines the fundamental issues and problems involved in assigning inequality contributions to components. Different...

This paper considers a wide class of inequality indices and identifies those which are additively decomposable. The sub-class of mean independent, additively decomposable measures turns out to be a single parameter family which includes the squared coefficient of variation and the two Theil's...

We provide the first estimate of the level and distribution of global household wealth. Mean assets and debts within countries are measured, partly or wholly, for 39 countries using household balance sheet and survey data centred on the year 2000. Determinants of mean financial assets,...

The theoretical analysis of tax progressivity has proceeded on the unrealistic assumption that tax liability is never zero, thereby precluding a systematic examination of the progressivity effects of such basic tax reforms as an increase in personal allowances. This paper extends the core...

Stochastic dominance and Lorenz dominance are examples of orderings which require unanimous agreement among an infinite set of indices. This paper considers various subsets of inequality measures that respect Lorenz dominance, and assesses the extent to which a small number of indices can...

We provide the first estimate of the level and distribution of global household wealth. The level of assets and debts for 39 countries are measured using household balance sheet and survey data centred on the year 2000. Average wealth holdings are imputed to countries lacking direct evidence....
