The key puzzle in the long-run economic history of the world is “Why did the Industrial Revolution occur in 1800, thousands of years after the development of the institutions necessary for economic growth?” according to Gregory Clark, professor of economics at UC Davis.
Here is a video of his Aug 13th, 2008 talk at the University of Canterbury. He talks about the central argument of this book, “A Farewell to Alms.” He also presents some new evidence to buttress that argument.
The slides he presents are hard to see in the video. But that should not be too hard for us to follow since we do have the hard copy of the book to read. I recommend watching his presentation, in addition to reading the book.
