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...

This research explores the origins of the variation in the prevalence and nature of political institutions across globe. It advances the hypothesis and establishes empirically that variation in the inherent diversity across human societies, as determined in the course of the exodus of Homo...

This research presents the first evidence that moderate fecundity had maximized long-run reproductive success in the human population. Using a reconstructed genealogy for nearly half a million individuals in Quebec during the 1608-1800 period, we find that while a high fecundity was associated...

The importance of the prehistoric migration of anatomically modern humans from Africa for comparative economic development has been the focus of a vibrant research agenda in the past decade. This influential literature has attracted the attention of some scholars from other disciplines, and in...

Exploiting a novel geo-referenced data set of population diversity across ethnic groups, this research advances the hypothesis and empirically establishes that variation in population diversity across human societies, as determined in the course of the exodus of human from Africa tens of...
