The economic theory of Marxism is one of the fundamental trends that continue the classical tradition in economic science. Like any body of theoretical knowledge, the economic theory of Marxism cannot become outdated; it can only be discarded by managerial practice as unwanted. Practice shows that within modern management, situations increasingly arise that can only be explained adequately within the framework of classical political economy. The awakening of interest in the classical tradition, and accordingly, in Marx's economic theory, is due to the fact that it retains within itself the whole indispensable set of instruments for economic analysis of the state of the modern economy. Moreover, the basic positions of Marxism coincide in some cases with ultra - modern (institutional) concepts. Today, a return to the ideas of Marxism is possible only on several conditions: a) if this theoretical current is cleansed of accumulated vulgarisms and distortions; b) if there is a rethinking of outmoded positions that have been disproved by reality; c) if Marxist methodology is employed for analysing the present - day economy. This course of instruction is aimed at the study and assimilation of the theoretical bases of the classical, politico - economic school in economic science - Marxism.
