Lecture 11 - Behavioral Finance and the Role of Psychology

Overview

Deviating from an absolute belief in the principle of rationality, Professor Shiller elaborates on human failings and foibles. Acknowledging impulses to exploit these weaknesses, he emphasizes the role of factors that keep these impulses in check, specifically the desire for praise-worthiness from Adam Smith's The Theory of Moral Sentiments. After a discourse on Personality Psychology, Professor Shiller starts a list of important topics in Behavioral Finance with Daniel Kahneman's and Amos Tversky's Prospect Theory. The value function and the probability weighting function, as two key components of this theory, help explain certain patterns in people's everyday decision making, e.g. the existence of diamond ring insurance and airline flight insurance. An in-class experiment underscores the prevalence and importance of the concept of overconfidence. Further topics include Regret Theory, gambling behavior, cognitive dissonance, anchoring, the representativeness heuristic, and social contagion. Professor Shiller concludes the lecture with some perspectives on moral judgment in the business world, addressing shared values and integrity.
