"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...

This study uses German social security records to provide novel evidence about the heterogeneity in life expectancy by lifetime earnings and, additionally, documents the distributional implications of this earnings-related heterogeneity. We find a strong association between lifetime earnings and...

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....

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...

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...

In this paper, we study how the tax-and-transfer system reduces the inequality of lifetime income by redistributing lifetime earnings between individuals with different skill endowments and by providing individuals with insurance against lifetime earnings risk. Based on a dynamic life-cycle...

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...

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,...

Drawing on a comprehensive compilation of quantile shares and inequality measures for 34 countries, including over 5,600 estimated Gini coefficients, we review the measurement of income inequality in Latin America and the Caribbean over the last seven decades. We find that there is quite a bit...

Scholars have sought to quantify the extent of inequality which is inherited from past generations in multiple ways, including a large body of work on intergenerational mobility and inequality of opportunity. This paper makes two contributions to that broad literature. First, we show that many...
