Since the 1950s, traditional financial models have dominated the field of finance. Traditional finance is based on the assumption that individuals are rational. The premise of investors' rationality, which results in the efficient operation of bond and stock markets, serves as the basis for traditional financial theories.

Standard finance is a paradigm of finance based on the concepts of Miller and Modigliani, the capital asset pricing model (CAPM) developed by Sharpe, Scholes, Linter, and Black and Merton, and Markowitz's Portfolio principles (Statman, 1999). Standard finance presupposes that participants in investment market make decisions in an effort to maximize their own self-interest. This presumption serves as the foundation for the concept of market rationality. Traditional finance theory, according to Jensen and Merckling (1994), is centered on the concept of "rational man", a person who is significantly distinct from the individual.
