Robert Shiller and Eugene Fama debate financial market theories

Economist Robert Shiller explores the relationship between financial systems and the concept of ‘animal spirits.’ He argues that excessive leverage leads to a cycle of financial, economic, and sovereign debt crises. Shiller suggests that the primary objective of fund managers is often the preservation of self-esteem rather than mere profit maximization.

In contrast, Eugene Fama utilized data from the University of Chicago’s Center for Research in Security Prices to support the efficient market hypothesis. Fama’s research posits that market speculation contributes to perfect market prices, a conclusion that remains controversial in the field of financial theory.
