ABSTRACT
Karl Marx value can be expressed only through money, as a "money-mediated" form of appearance registering the general exchangeability of commodities. D. Ricardo criticised the quantity theory of money on the basis of the argument that money "has an intrinsic value". Marx initially describes money in the context of its functions as a measure of value as a standard of prices and as a medium of circulation - during the process of exchange, in accordance with the formula commodity-money-commodity. Marx formulated and then developed the theory of capital on the basis of the concept of value. The capitalist appears on the market as the owner of money buying commodities which consist of means of production and labour power. Surplus-value production is a process of exploitation of the labourers by the capitalist. According to Marx's theory, the capitalist productive process is simultaneously a process of exploitation and domination of the working class by the class of capitalists.
