Abigail L. Swingen, Competing Visions of Empire: Labor, Slavery, and the Origins of the British Atlantic Empire (New Haven: Yale University Press, 2015).
There have been some fantastic new contributions of late that explore connections between slavery, economics, and empire. In his 2008 analysis of the American political economy, economic historian Gavin Wright concluded that the dependence on slave labor came not because of any institutional efficiency on the part of plantations, but rather, that no other form of coerced labor could have been made to meet the labor demands. Sven Beckart’s Bancroft Prize-winning book, Empire of Cotton, analyzes connections between cotton, and the slave labor behind it, and the rise of modern capitalism. Ed Baptist’s book, The Half Has Never Been Told, explores slavery’s role in the making of American capitalism.
