The Side Effects of Immunity: Malaria and African Slavery in the United States
研究揭示疟疾引入美国后，对疟疾有抵抗力的劳动力需求激增，导致非洲奴隶在疟疾高发区大规模扩张，且来自非洲疟疾重灾区的奴隶价格更高。
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 significantly higher prices.
