Alan, in addition to those already sent you, I would add the following: 1) Eric Williams, _Capitalism and Slavery_ (1944) - a classic on the topic, the author's (later the PM of Trinidad and Tobago) Howard U. Ph.D. dissertation, argues that the slave trade was key to capitalist development, along with Walter Rodney's argument (in How Europe Underdeveloped Africa) that the underdevelopment of Africa was also the result of the same historical system, comprises the "Williams-Rodney" thesis. 2) William Darity, Jr., "A Model of Original Sin: Rise of the West and the Lag of the Rest," _American Economic Review_ (1992), follows in the Williams-Rodney tradition, showing that various mercantilist authors (e.g., Josiah Child, Thomas Dalby) also understood how the slave trade contributed to capitalist development. Theoretically draws on Hirschman's ideas of forward and backward intersectoral linkages to show the connections between the slave trade and the rise of industries such as gun-making, shipbuilding, sugar, textile, etc. also by the same author: 3) William Darity, Jr. "The Numbers Game and the Profitability of the British Trade in Slaves" _The Journal of Economic History_ (1985). 4) Bailey, Ronald, 1992, "The Slave(ry) Trade and the Development of Capitalism in the United States," in J. Inikori and S. Engerman (eds.): _The Atlantic Slave Trade_, Duke University Press (reprint from Social Science History, 1990). - also in the Williams-Rodney tradition, title speaks for itself, also other contributions in the same volume, and other important articles by the same author, such as: 5) Bailey, Ronald, 1997, "Out of Sight, Out of Mind" in T. Boston (ed.): A Different Vision, Volume Two, London: Routledge. 6) Oliver Cromwell Cox, _Caste, Class, and Race_ (1948) - another classic, by the great African-American Marxist sociologist, I even call the thesis the "Williams-Rodney-Cox" thesis, as Cox's arguments complement and complete the argument made by Williams that racism was the result not the cause of the Enslavement: because the slave trade was profitable, it was justified by racism. 7) Darity, "Mercantilism, Slavery, and the Industrial Revolution," _Research in Political Economy_ (1982) - along the same lines as the author's other contributions 8) Darity, "British Industry and the West Indian Plantations" _Social Science History_ (1990) - ditto For more, let me know.
