Behavioral economics and anomalies: An analysis on the BIST

Behavioral economic theory has revealed the realistic individual approach, which expresses the limited rational individual instead of the rational and mechanical individual understanding. As a result of studies conducted in recent years, it has been determined that individuals do not comply with the definition of human in the traditional economic model. On the other hand, studies in the field of behavioral economics have shown that human-specific factors are effective in the decision-making process. The aim of this study; It is to explain the reason for the volatility in the Bist-100 return price dollar index in terms of behavioral finance and to determine how investors behave while making their decisions. In this study, Bist-100 price-dollar index was used as dependent variable, CDS, RİSE, VIX and real TL interest rate were used as independent variables between 2008 and 2021. In the analysis, unit root tests, ARDL bounds test and Toda Yamamoto causality test were applied, respectively. As a result, it has been observed that financial decisions include complexity and uncertainty for individuals.
