In the context of diversification of knowledge in finance (Schinckus, 2008), behavioral
finance is a new approach which studies the financial reality by taking into account the
psychological dimension of investment. In the past 30 years, neoclassical finance and its
masterpieces1 have been challenged by empirical evidence and psychological studies.2
Progressively, behavioral finance has become a strong alternative framework to
neoclassical finance and some authors (Thaler, 1999) do not hesitate to present this field
as the future main paradigm of financial economics.
The emergence of the behavioral approach in finance is generally dated back to the 1980s
(Schinckus, 2009), but a few papers are dedicated to the presentation of the investors’
behavioral analysis developed in the first part of the 20th century. In their book entitled, The
Story of Behavioral Finance, Adams and Finn (2006) date the emergence of this paradigm in
the 1980s as the result of a convergence of the advances in psychology and financial
economics. Schleifer (2002, p. vi) explains that when he was a graduate student in the 1980s,
“there were only a handful of academic papers in behavioral finance written by people like
Robert Shiller, Larry Summers and Richard Thaller”. According to Shefrin (2002, p. 7),
behavioral finance burgeoned when the advances made by psychologists came to the
attention of the economists. The author claims that we had to wait until the 1980s to have,
in finance, a true behavioral perspective founded on an organized body of knowledge. |
