In response to a growing interest in comparing inequality levels and trends across countries, a number of cross-national inequality databases are now available. These databases differ considerably in purpose, coverage, data sources, inclusion and exclusion criteria, and quality of documentation....

The Gini coefficient of labor earnings in Brazil fell by nearly a fifth between 1995 and 2012, from 0.50 to 0.41. The decline in earnings inequality was even larger by other measures, with the 90-10 percentile ratio falling by almost 40 percent. Although the conventional explanation of a falling...

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....

"Shared prosperity" has become a common phrase in the development policy discourse. This short paper provides its most widely used operational definition - the growth rate in the average income of the poorest 40 percent of a country's population - and describes its origins. The paper discusses...

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...

Income differences arise from many sources. While some kinds of inequality, caused by effort differences, might be associated with faster economic growth, other kinds, arising from unequal opportunities for investment, might be detrimental to economic progress. We construct two new metadata...

We axiomatically characterize two classes of poverty measures which are sensitive to inequality of opportunity - one a strict subset of the other. The proposed indices are sensitive not only to income shortfalls from the poverty line, but also to differences in opportunities faced by people with...

Thirty years after the "Washington Consensus", is there a new policy consensus that addresses the problem of inequality? This paper argues that there is widespread acceptance that multiple, interrelated and mutually reinforcing inequalities exist - in income, wealth, education, health, power,...

This paper asks whether prioritarianism - the view that social welfare orderings should give explicit priority to the worse-off - is consistent with the normative theory of equality of opportunity. We show that there are inherent tensions between some of the axioms underpinning prioritarianism...
