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...

"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 paper explores the question of structural transformation and income distribution through the eyes of the pioneer in such analysis, Simon Kuznets. It argues that his 1955 paper stands the test of time in providing insights which are relevant to understanding current phenomena like the...

Both raw intuition and past experience suggest that the success of an employment guarantee scheme (EGS) in safeguarding the welfare of the poor depends both on the wage it promises, and the ease with which any worker can gain access. An EGS is thus at once a wage guarantee and a rationing...

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....

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....

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...

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...

Wealthy individuals often voluntarily provide public goods that the poor also consume. Such philanthropy is perceived as legitimizing one's wealth. Governments routinely exempt the rich from taxation on grounds of their charitable expenditure. We examine the normative logic of this exemption. We...

In this paper we argue that the decline in global inequality over the last decades has spurred a 'sunshine' narrative of falling global inequality that has been rather oversold, in the sense, we argue, it is likely to be temporary. We argue the decline in global inequality will reverse due to...
