The dualistic theory of value and the prculiarities of studying economics as a complex system

Abstract

The article analyzes the cognitive potential of the classical paradigm and the theory of K. Marx for understanding the systemic connections of economics. The model of an isolated economy is considered as a prerequisite for studying the logic of the formation of basic economic notions. The author reveals the peculiarities of K.Marx’s dualistic approach to the analysis of value relationships, as well as to the development of the theory of supply of goods and to the theory of demand. The importance of this approach is shown for revising the ideas about the cost and productivity of labor as basic categories, as well as about the whole categorial grid of economic theory.
