The slave trades out of Africa represent one of the most significant forced migration experiences in history. In this paper, I illustrate their long-term consequences on contemporaneous socio-economic outcomes, drawing from my own previous work on the topic and from an extensive review of the available literature. I first consider the influence of the slave trade on the "sending" countries in Africa, with attention to their economic, institutional, demographic, and social implications. Next, I evaluate the consequences of the slave trade on the "receiving" countries in the Americas. Here, I distinguish between the case of Latin America and that of the USA. Overall, I show that the slave trades exert a lasting impact along several contemporaneous socio-economic dimensions and across diverse areas of the world.
