Valor, essência e aparência e o conceito da mais-valia extraordinária

In the context of the discussion about the concept of extraordinary surplus-value, within the Brazilian Society of Economic Policy, raised by Francisco Paulo Cipolla (UFPR) in an article published by the entity’s publication (june 2003), this article proposes an articulation of the value and price concepts from wich the extraordinary surplus-value results as the only possibility of functional expression of the profit phenomenon. In this rereading of Marx, in a moderne perspective, although the concept of absolute-surplus-value is recognized as pertinent and as one of many ways through wich, historically, capital unduly misappropriates the surplus wich is functionally owned to labor, and deprivies it - in behalf of the extraordinary surplus-value - of the function of structuring a theoretical explanation of profit, in a modern perspective.
