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.
