Data and Code for: The Side Effects of Immunity: African Slavery in the United States

This paper documents the role of malaria in the diffusion of African slavery in the United States. The novel empirical evidence reveals that the introduction of malaria triggered a demand for malaria-resistant labor, which led to a massive expansion of African enslaved workers in the more malaria-infested areas. Further results document that, among African slaves, more malaria-resistant individuals, i.e. those born in the most malaria-ridden regions of Africa, commanded signicantly higher prices.<br><br>
