For most of human history, economic growth was, well, pretty bleak. But around the Enlightenment, things started clicking. This year's Nobel Memorial Prize in Economic Sciences went to a trio of researchers whose work focuses on how technological progress led to this sustained economic growth. Today we hear from one of them, Joel Mokyr, about his work on European economic history.
