Using a new dataset, we investigate the determinants of violence against women in Africa. We focus on cultural factors arising from pre-colonial customs and find evidence consistent with two hypotheses. First, ancient socioeconomic conditions determine social norms about gender roles, family...

We study the impact of plausibly exogenous global food price shocks on local violence across the African continent. In food-producing areas, higher food prices reduce conflict over the control of territory (what we call "factor conflict") and increase conflict over the appropriation of surplus...
