I use newly-developed data on Africa to estimate the effects of the international slave trades (circa 1500–1850) on the institutional structures of African economies and societies (circa 1900). I find that: (1) societies in slave catchment zones adopted slavery to defend against further enslavement; (2) slave trades spread slavery and polygyny together; (3) politically centralized aristocratic slave regimes emerge in West Africa and family-based accumulations of slave wealth in East Africa. I discuss implications for literatures on long-term legacies in African political and economic development.

国际奴隶如何交易不发达的非洲

我使用新开发的非洲数据来估计国际奴隶贸易（大约 1500-1850 年）对非洲经济和社会制度结构（大约 1900 年）的影响。我发现：（1）奴隶集结区的社会采用奴隶制来抵御进一步的奴役；(2) 奴隶贸易将奴隶制和一夫多妻制传播在一起；(3) 西非出现政治集中的贵族奴隶制政权，东非出现以家庭为基础的奴隶财富积累。我讨论了有关非洲政治和经济发展中长期遗产的文献的意义。
