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...

This paper develops a criterion of opportunity equalization, that is consistent with theoretical views of equality of opportunity. Our analysis rests on the characterization of inequality of opportunity as a situation where some groups in society enjoy an illegitimate advantage. In this context,...

This paper looks at the association between wage satisfaction and different notions of reference wage, based on a matched employer-employee dataset. It shows that workers’ satisfaction depends on other-people’s income in different ways. Relative income concerns are important, but we also...

This paper introduces a new Lorenz dominance criterion that allows ranking income distributions according to ray-invariant intermediate inequality measures. In doing so, it defines a-Lorenz curves by adapting the generalized Lorenz curves to this case. In addition, it provides an empirical...

A widely accepted criterion for pro-poorness of an income growth pattern is that it should reduce a (chosen) measure of poverty by more than if all incomes were growing equiproportionately. Inequality reduction is not generally seen as either necessary or sufficient for pro-poorness. As shown in...

Previous estimates of unfair inequality of opportunity (IOp) are only lower bounds because of the unobservability of the full set of endowed circumstances beyond the sphere of individual responsibility. In this paper, we suggest a new estimator based on a fixed effects panel model which...

The paper examines the identification of the “middle class” using data from LIS and LWS. It first considers definitions based purely on income, examining the rationale for different approaches and illustrating the implications for changes over time. It argues that the concept of “class”...
