O aumento da taxa de mais-valia como contratendência à queda da taxa de lucro

Abstract

The article discusses two issues related to Marx’s law of the tendential fall in the rate of profit. Firstly, it resumes the discussion about one of Marx’s assumptions in the formulation of the law: whether the rate of surplus value remains constant, its increase being considered only later, when analyzing the countertendencies; or whetherthe rate of surplus value increases, its increase deriving, in this case, from the increase in labor productivity. Secondly, it discusses whether the increase in the rate of surplus value resulting from the increase in labor productivity should be considered as a countertendency, or whether the status of countertendency should be restricted to increases in the rate of surplus value that assume the organic composition of capital to be constant, resulting from the prolongation of the working day and certain methods of labour intensification.
