“People in Traditional Finance are rational. People in Behavioral Finance are normal.”
Mier Statman, Ph.D.
Behavioral finance as behavioral economics and is further defined as combining the twin discipline of psychology and economics to explain why and how people make seemingly irrational or illogical decisions, and why they save, invest, spend, and borrow money.
Belsky and Gilowich (1999)
Behavioral finance tries to understand how people forget fundamentals and make investments based on emotions.
Verma (2004)
asserts that behavioral finance is the study of the influence of psychology on the behavior of financial practitioners and the subsequent effect on markets.
Swell (2005)
