The paper is devoted to critical analysis of economic methodology movement equating models and metaphors, without making any difference between mathematic models and verbal descriptions ("stories"). The author characterizes some approaches to models' methodological treatment in economics; describes models' features permitting to obtain new knowledge and, finally, validates the lack of these features in most verbal descriptions of economic processes. The analysis shows that models and verbal stories have essentially different cognitive potential for economics' development.

To understand the depth of transformations in all spheres of society generated by
migration, new terminology is needed. The notion of "postmigrant societies" implies that the
distinction between local and migrant population loses its relevance in certain social spheres.
According to the familiar epistemological framework, societies are presented as consisting of
"local population" on the one hand, and "migrant population" on the other. This understanding,
however, is becoming obsolete. First, it does not reflect the fact that the phenomenon of spatial
mobility is embedded in the social structure. A significant part of the so-called local population
is itself included in migration processes. People who are considered to be part of the
"autochthonous population" are in fact migrants themselves due to different circumstances
(contract work, long-term stay in another country due to studies, involvement in joint business
projects, participation in international scientific teams, availability of real estate abroad, etc.). At
the same time, those people who are regarded as "migrants" by common sense can be well
integrated into the social institutions of their new homeland. Second, the traditional
epistemological framework does not reflect contemporary demographic trends. It is unable to
capture two points: (a) population rotation within the framework of circular/pendulum migration;
(b) qualitative change in the urban population of industrialized countries.

The concept of permanent revolution was formulated in the XIX century became a subject of constant debate in humanities circle. In contrast-scientific and technological revolutions are natural components at all steps of human development. Their permanence is commonly recognized imperative, followed by numerous confirmations with a convincing inevitability. Information and industrial revolutions taking place now in the world are such evidences. Experts declare today the fourth industrial revolution. Peter Drucker fairly predicted the fourth information revolution. It is interesting that the most important trait of both revolutions is the artificial intelligence which functions in the sphere of Big Data and Internet of Things. The application field (not the only) is the economy-its structure and content. Experts state the emergence of information capitalism and the information economy — innovations obtaining special and revolutional traits. The article is devoted to analysis of main components of the innovations and offers the ways how they should be reflected in the curriculum for modern economists and managers.

Modern economic science studies the behavior of an individual making choice in conditions of limited resources, and seeking to satisfy his own interests as a result of this choice. Economics is a social science as it studies the behavior of an individual which involves the interests of other people and communities. Economics is close to natural sciences as it considers the behavior of an individual in a material world of limited resources. Besides, a human being may be considered as a material system in which there are certain biological processes influencing its behavior. The question of how fully can economics use methodological assumptions of natural sciences, is sharply debatable. The author's position is that the cooperation between economics and natural sciences has both objective grounds and objective problems. In any case, economics is not a natural science, and the natural sciences shouldn't have a priority in this dialogue. It is only a new stage in self-reflection of different sciences. The importance of this research is defined by the need of studying the scientific status of economics and the prospects of its development in terms of the subject and methodology.
