Prof. William Goetzmann: Learning from Financial Market History (EP.248)
The Rational Reminder Podcast
The Long-Term History of the Stock Market
If you want to understand the deep rhythms of markets and society, you really have to take a long-term historical view. Over very long stretches of time, the stock market returns some amount in a relatively narrow band once you control for things like inflation. It could take you 20, 30, 40 years to really understand what the expected return or what the average historical return is. But we like to think that once you've discovered something that makes money, it's going to keep on going before you can put any kind of boundary under it at all.
How the financial system works and how we interact with it has grown in complex ways and is a fascinating but nuanced topic. To guide us through the history of the economy is Professor William Goetzmann, who is an expert in finance, economics and art history, and whose research has been featured in top publications. As a highly respected scholar, he's authored numerous books on topics such as real estate and behavioural finance. It is fair to say Professor Goetzmann's work has left a significant impact on both academia and the world. In our conversation, we dive into financial market history and explore more than just broad market returns. We unpack the fascinating phenomenon of economic bubbles and booms, and how they have evolved and shaped the financial system. He also shares crucial insights from the past and advice for investors looking to leverage the market. And to wrap things up, Professor Goetzmann shares his views on money after digging deep into its historical roots. Tune in to unlock the secrets of the past and gain valuable insights for the future as we journey through the fascinating world of economic history. Tune in now!
