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...

This study examines empirically the impact of income polarization on economic growth in an unbalanced panel of more than 70 countries during the 1960–2005 period. We calculate various polarization indices using existing micro-level datasets, as well as datasets reconstructed from grouped data...

Theoretical and empirical studies exploring the effects of income inequality upon growth reach a disappointing inconclusive result. This paper postulates that one reason for this ambiguity is that income inequality is actually a composite measure of at least two different sorts of inequality:...

Evidence of an increase in inequality since the 1970s has motivated research on its relationship to growth and development. The findings of that research are contradictory and inconclusive. One source of these divergent results is that researchers rely on different group measures of inequality....

In this paper we argue that a better understanding of the relationship between inequality and growth can be obtained by shifting the analysis from the space of final achievements to the space of opportunities. To this end, we introduce the Opportunity Growth Incidence Curve (OGIC) that can be...

This paper frames growth incidence analysis within the logic of social impact evaluation understood as an assessment of variations in individual and social outcomes attributable to shocks and policies. It uses recentered influence function (RIF) regression to link the growth incidence curve...
