Today our guest is Professor William Goetzmann, here to talk about his book Money Changes Everything: How Finance Made Civilization Possible. Will is the Edwin J. Beinecke Professor of Finance and Management Studies and Faculty Director of the International Center for Finance at the Yale School of Management. I think of him as sort of an economic archeologist and polymath whose past work includes stock market predictability, alternative investing, factor investing, behavioral finance and the art market to name a few. Professor Goetzmann has written and co-authored a number of books, two of my personal favorites in addition to our conversation today are The Origins of Value: The Financial Innovations that Created Modern Capital Markets and The Great Mirror of Folly: Finance, Culture and the Crash of 1720 –both of which he contributed to and edited.
