The main task of economic theory is to give an explanation of the events taking place in economic life with the help of models of reality. Therefore, it is customary to distinguish between positive economic theory, the purpose of which is to study the behavior of economic agents, and normative theory, the purpose of which is the development of economic policy.
The subject of study of economic theory is the behavior of an economic agent in a certain economic system. By "Economic agent" is meant not a real person or group of people, but a simplified (idealized) model that is convenient for analysis. To study behavior, economics models the process of individual choice from a set of options under the condition of limited resources. All economic processes at the group level and at the macro level are interpreted as the result of many individual decisions. Correct aggregation of individual solutions is a problem in itself.
Economic theory consists of three main sections: microeconomics, macroeconomics and econometrics. Basic models and concepts are used in narrower areas of science: the theory of economic growth, development economics, international economics (the theory of international trade and the theory of international finance), economics of the public sector, the theory of industrial markets, the theory of auctions, various sections of finance and other areas.
The methodology of economic science and the history of economic doctrines are directly adjacent to economic theory. In addition, a large amount of research is carried out at the interface with other social sciences: history, law, criminology, sociology, political science, as well as neurobiology and psychology (neuroeconomics).
