This book provides, for the first time, a systematic and comprehensive narrative of the history of one central idea in economics, namely the division of labour, over the past two and a half millennia, with special focus on that having occurred in the most recent two and a half centuries. Quite contrary to the widely held belief, the idea has a fascinating biography, much richer than that exemplified by the pin-making story that was popularized by Adam Smith’s classical work published in 1776.
