Research spanning various disciplines underscores the significance of cultural diversity in facilitating cross-pollination of ideas, while diminishing social cohesiveness. Yet, the exploration of the impact of an equally intriguing dimension of diversity has remained uncharted: has the...

This research explores the effects of within-group heterogeneity on group-level productivity. It establishes that observed genetic diversity of 230 worldwide ethnic groups, as well as predicted genetic diversity of 1,331 ethnic groups across the globe, has a hump-shaped effect on economic...

This research explores the persistent effect of the Neolithic Revolution on the evolution of life expectancy in the course of human history. It advances the hypothesis and establishes empirically that the onset of the Neolithic Revolution and the associated rise in infectious diseases triggered...

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

Evidence suggests that the prehistoric Out of Africa Migration has impacted the degree of intra-population genetic and phenotypic diversity across the globe. This paper provides the first evidence that this migration has shaped cultural diversity. Leveraging a folklore catalogue of 958 oral...
