|March 2017||Roots of Autocracy|
with Oded Galor: w23301
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 thousands of years ago, contributed to the differential formation of pre-colonial autocratic institutions within ethnic groups and the emergence of autocratic institutions across countries. Diversity has amplified the importance of institutions in mitigating the adverse effects of non-cohesiveness on productivity, while contributing to the scope for domination, leading to the formation of institutions of the autocratic type.
|April 2015||Diversity and Conflict|
with Cemal Eren Arbatlı, Quamrul H. Ashraf, Oded Galor: w21079
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 nations and ethnic groups, it demonstrates that population diversity, as determined predominantly during the exodus of humans from Africa tens of thousands of years ago, has contributed significantly to the risk and intensity of historical and contemporary civil conflicts. The findings arguably reflect the adverse effect of population diversity on interpersonal trust, its contribution to divergence in preferences for public goods and redistributive policies, and its impact on the degree of fractional...
|September 2014||The Biocultural Origins of Human Capital Formation|
with Oded Galor: w20474
This research explores the biocultural origins of human capital formation. It presents the first evidence that moderate fecundity and thus predisposition towards investment in child quality was conducive for long-run reproductive success within the human species. Using an extensive genealogical record for nearly half a million individuals in Quebec from the sixteenth to the eighteenth centuries, the study explores the effect of fecundity on the number of descendants of early inhabitants in the subsequent four generations. The research exploits variation in the random component of the time interval between the date of first marriage and the first birth to establish that while higher fecundity is associated with a larger number of children, an intermediate level maximizes long-run reproducti...
