Theoretical and methodological grounds of mainstream and their application in the context of shadow economy

The goal of the article lies in the study of basic theoretical and methodological prerequisites and principles of modern mainstream and also possibilities of their application in the context of shadow economy. Analysing and generalising economic theories of Nobel laureates, the article considers problems of limited rationality, information asymmetry and opportunistic behaviour of economic agents. The article justifies preferences of the institutional direction as the most appropriate to real conditions of the market activity of subjects of shadow economy. Prospects of further studies are analysis and modification of the theory of economic crimes with consideration of specific features of the shadow component of national economy.
