Solow provides important insights for understanding the economics of slavery in the Americas. This posthumous volume brings together some of her seminal publications based on her research throughout the past twenty-five years. It well deserves to be collected in a convenient volume for scholars who study slavery in the Americas. The central theme is the significance of the institution of slavery in modern economic development. Always written with a brilliance and flare, Solow’s work ably outlines the basic features of slavery as a system and economic structure. Although her analysis is heavily weighted toward British and North American history, her explanation of slavery’s underpinnings in economic terms applies to any society in any time period.
