This article examines the role of cognitive ability or intelligence on slave exports from Africa. We test a hypothesis that countries which were endowed with higher levels of cognitive ability were more likely to experience lower levels of slave exports from Africa probably due to comparatively better capacities to organize, co-operate, oversee and confront slave traders. The investigated hypothesis is valid from alternative specifications involving varying conditioning information sets. The findings are also robust to the control of outliers. JEL: I20, I29, N30

非洲的情报和奴隶出口

本文探讨了认知能力或智力对非洲奴隶出口的作用。我们检验了一个假设，即具有较高认知能力的国家更有可能经历来自非洲的奴隶出口量较低的情况，这可能是由于组织，合作，监督和对抗奴隶贸易者的能力相对较强。从涉及不同条件信息集的替代规范中，所研究的假设是有效的。这些发现对于控制异常值也很可靠。JEL：I20，I29，N30
