Is the brain drain a curse or a boon for developing countries? This paper reviews what is known to date about the magnitude of the brain drain from developing to developed countries, its determinants and the way it affects the well-being of those left behind. First, I present alternative...

While gender gaps in average math performance are close to zero in developed countries, women are still strongly underrepresented among math high performers. Using data from five successive waves of the Programme for International Student Assessment (PISA), we show that this underrepresentation...

Why does inequality vary across societies? We advance the hypothesis that in a market economy, where earning differentials reflect variations in productive traits among individuals, a significant component of the differences in inequality across societies can be attributed to variation in...

For a large set of countries, we document how the labor earnings inequality varies with GDP per capita. As countries get richer, the mean-to-median ratio and the Gini coefficient decline. Yet, this decline masks divergent patterns: while inequality at the top of the earnings distribution falls,...

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...

Social scientists study two kinds of inequality: inequality between persons (as in income inequality) and inequality between subgroups (as in racial inequality). This paper analyzes the mathematical connections between the two kinds of inequality. The paper proceeds by exploring a set of...

Since Aristotle, a vast literature has suggested that economic inequality has important political consequences. Higher inequality is thought to increase demand for government income redistribution in democracies and to discourage democratization and promote class conflict and revolution in...

The widespread consumer adoption of low-carbon technologies (LCTs) is a cornerstone of net zero targets worldwide, however LCTs may not be equally distributed across socioeconomic characteristics. Our paper contributes to the literature by exploring socioeconomic inequality in LCT adoption and...
