As especificidades da mercadoria força de trabalho: Marx revisitado

Coming along with Polanyi's ideas of fictitious commodity, this paper seeks to reveal the logical inconsistencies and silents in the economic science arguments on the labor force as a commodity. Once Marx's influence on the anti-capitalist movements is outstanding, we need to show his contribution, through his economic thought, to the scientific economism. As is well known, when proposed that the commodity sell by the worker was the 'labor force' instead the labor, as the classical economists used to say, Marx was able to built his theory on the capitalist economy theory, which relies on the concept of surplus value.. That is the reason why the paper is specially concern with the failures or weaknesses present in one of the huge Marx contribution to the economics thought: the concept of labor force. (English)
