We study the long-term determinants of the high rates of HIV infection in sub-Saharan Africa, particularly among women, with a focus on family structure and sexual behavior as shaped by the demographic shock following the transatlantic slave trade. First we show that, in clusters where polygyny...

We revisit the effect of long run income growth on population fertility in some of the poorest countries in the world. Causal inference is enabled through proxying income windfalls by oil price shocks in oil rich versus oil poor provinces. Using various fertility measures as outcomes, we find...

We explore the effect of historical ethnic borders on contemporary conflict in Africa. We document that both the intensive and extensive margins of contemporary conflict are higher close to historical ethnic borders. Exploiting variations across artificial regions within an ethnicity's...
