Building on earlier work by political philosophers, economists have recently sought to define a concept of equity that accommodates the fairness of reward to individual responsibility and effort, while allowing for the existence of some inequalities which are unfair and should be compensated....

Taxes and transfers can have significant impacts on poverty and inequality. All standard measures are by definition anonymous in the sense that we do not know the identity of winners and losers. That a given combination of taxes and transfers makes some of the poor poorer, however, may be...

Despite a recent surge in the number of studies attempting to measure inequality of opportunity in various countries, methodological differences have so far prevented meaningful international comparisons. This paper presents a comparison of ex-ante measures of inequality of economic opportunity...

The paper defines the Gini index as the sum of individual contributions where individual contributions are interpreted as the degree of diversity of each individual from all other members of society.

In the literature there are a number of generalizations of the Gini coefficient which inherit most of its appealing properties. These families allow the incorporation of different value judgments and all of them are more sensitive to transfers among the poorest individuals in society than to...

We apply a standard tax and benefit incidence analysis to estimate the impact on inequality and poverty of direct taxes, indirect taxes and subsidies, and social spending (cash and food transfers and in-kind transfers in education and health). The extent of inequality reduction induced by direct...
