In Marxian economics, the equivalent to Schumpeterian rent is the extra surplus value that is extracted from the laborer during the rise of local productivity, meaning the development of the productive forces through innovation owned by the respective capitalist, while all other enterprises are left with yet undeveloped productive forces. The result is the rise of the local rate of profit, as the respective commodity is now produced cheaper by this enterprise alone, yet can still be sold for its general market price. In Marxian theory, the earning of extra surplus value is what drives and guides the capitalist, and thus capitalism itself.[3]
