Andrei Shleifer | Crisis of Beliefs: A New Model of Investor Psychology

In Episode 70 of Hidden Forces, Demetri Kofinas speaks with Andrei Shleifer, professor of economics at Harvard University. Dr. Shleifer is the most cited economist in the world according to RePEc’s database. Throughout the course of his career, Andrei Shleifer has worked in the areas of comparative corporate governance, law & finance, behavioral finance, as well as institutional economics. He has published seven books, including, A Crisis of Beliefs: Investor Psychology and Financial Fragility with his co-author Nicola Gennaioli.   

Demetri’s conversation with Andrei centers on the subject of beliefs: how they impact markets and how economists and financial practitioners are attempting to model them using data about people’s expectations, assumptions, and attitudes in order to make better-informed investment and policy decisions.

The first half of the episode is devoted to exploring the mechanics of the 2007-2008 credit crisis, and the role played by structured products and derivatives, off-balance sheet vehicles, money market funds, GSE’s, and a policy of ultra-low interest rates that fueled over-confidence in the power of regulators and in the sustainability of the status quo. In the second half, Dr. Shleifer provides us with a more formal approach to thinking about Hyman Minsky’s instability hypothesis and how market participants can draw radically different conclusions about that same data when their beliefs about the world change dramatically.

Given the destabilizing forces of populist politics, trade tensions, and changing geopolitical fault lines, the ability to draw valuable insights from data about expectations and beliefs is invaluable for any investor or policymaker looking to gain a sense of market sentiment: where it stands and where it might be going.
