My book on labor input and productivity growth in England during the Industrial Revolution has been published by OUP in 2001. Reviewers have called it "both novel and ingenious" (Greg Clark, JEH) "bold, original, intelligent, and important" (Penelope Corfield, Business History Review), "important and impressive" (Jon White, English History Review), "surely .. one of the most influential books ever written both on the industrial revolution and on the issue of time use ... a masterpiece of econometric history" (Social History Society Bulletin). You can buy it from Oxford University Press,  Amazon and selected booksellers.
