This essay explores the deepest roots of comparative economic development. It underscores the significance of evolutionary processes since the Neolithic Revolution in shaping a society's endowment of fundamental traits, such as predisposition towards child quality, time preference, loss...

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...

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...

This research advances the hypothesis and establishes empirically that interpersonal population diversity has contributed significantly to the emergence, prevalence, recurrence, and severity of intrasocietal conflicts. Exploiting an exogenous source of variations in population diversity across...

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...

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 income inequality across societies can be attributed to...

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...

We question the received wisdom that birth limitation was absent among historical populations before the fertility transition of the late nineteenth-century. Using duration and panel models on family-level data, we find a causal, negative short-run effect of living standards on birth spacing in...

We use duration models on a well-known historical dataset of more than 15,000 families and 60,000 births in England for the period 1540-1850 to show that the sampled families adjusted the timing of their births in accordance with the economic conditions as well as their stock of dependent...

We provide a simple framework for interpreting instrumental variable regressions when there is a gap in time between the impact of the instrument and the measurement of the endogenous variable, highlighting a particular violation of the exclusion restriction that can arise in this setting. In...
