We investigate the historical origins of mistrust within Africa. Combining contemporary household survey data with historic data on slave shipments, we show that individuals whose ancestors were heavily raided during the slave trade today exhibit less trust in neighbors, relatives, and their local government. We confirm that the relationship is causal by using the historic distance from the coast of a respondent’s ancestors as an instrument for the intensity of the slave trade, while controlling for the individual’s current distance from the coast. We undertake a number of falsification tests, all of which suggest that the necessary exclusion restriction is satisfied. Exploiting variation among individuals who live in locations different from their ancestors, we show that most of the impact of the slave trade works through factors that are internal to the individual, such as cultural norms, beliefs, and values.
Como? Bem, vamos aos autores:
Using fine-grained individual-level survey data, we test whether the slave trade caused a culture of mistrust to develop within Africa. Early in the slave trade, slaves were primarily captured through state organized raids and warfare. By the end of the trade, because of the environment of ubiquitous insecurity that had developed, individuals – even friends and family members – began to turn on one another, kidnapping, tricking, and selling each other into slavery (e.g., Koelle, 1854, Hair, 1965, Piot, 1996). We hypothesize that in this environment, where everyone had to constantly be on guard against being sold or tricked into slavery by those around them, a culture of mistrust may have evolved, and that this mistrust may continue to persist today.
