This paper studies the effects of bilateral foreign aid on conflict escalation and de-escalation. We make three major contributions. First, we combine data on civil wars with data on low level conflicts in a new ordinal measure capturing the two-sided and multifaceted nature of conflict. Second,...

This research explores the economic causes and consequences of language structures. It advances the hypothesis and establishes empirically that variations in pre-industrial geographical characteristics that were conducive to higher return to agricultural investment, larger gender gap in...

The importance of evolutionary forces for comparative economic performance across societies has been the focus of a vibrant literature, highlighting the roles played by the Neolithic Revolution and the prehistoric “out of Africa” migration of anatomically modern humans in generating...

This research establishes that the emergence, prevalence, recurrence, and severity of intrastate conflicts in the modern era reflect the long shadow of prehistory. Exploiting variations across national populations, it demonstrates that genetic diversity, as determined predominantly during the...

This paper defines economic slumps as sequences of structural breaks exhibiting a specific pattern. We identify 58 such episodes between 1950 and 2008 among 138 countries, and then examine the phases of decline and their duration. In some countries declines last extremely long, and we put...

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 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...

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...

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 essay explores the deepest roots of economic development. It underscores the significance of evolutionary processes in shaping fundamental individual and cultural traits, such as time preference, risk and loss aversion, and predisposition towards child quality, that have contributed to...
