Conventional economics and behavioral economics; Subscriptions and differences

According to Marshall, most human behavior is based on intuitive cognitive systems. Psychologists have shown that new methods of rationality follow categorical patterns, which traditional theories of economics cannot explain. Tyler also proved that people do not behave in accordance with economic theories, and in fact, the connection and cooperation of several disciplines can improve the existing gaps. Therefore, the purpose of this study is to study conventional economics and behavioral economics and to study and recognize consumer behavior. The method used in the present study is applied in terms of purpose and descriptive-survey in terms of data collection. Structural equation modeling has been used to study the conceptual model and research hypotheses. The statistical population of this study included 350 graduate students of economics at the University of Tehran in 1399. Using simple random sampling method and Cochran's formula, 183 people were selected as the statistical sample size. Using the data obtained from the questionnaire and with the help of Smart PLS statistical software, the degree of reliability was measured by measuring Cronbach's alpha and combined reliability. Finally, we came to the conclusion that there is a positive and significant relationship between behavioral economics (with the dimensions of past feelings and emotions, intuition, other people's decisions and how to express the problem and beliefs and values) and decisions of conventional economics. The present study also shows that behavioral economics increases the explanatory power of economic models, and ultimately suggests more appropriate macro policies. We also concluded that behavioral economics and consumer behavior are largely compatible with the view of the Holy Qur'an, and that conventional economics is less adaptable; These results show the truth of consumer behavior.
