Valeur, prix de (re)production et développement économique

This paper has two aims. Firstly, it has a pedagogical object : it talks about the theoretical controversies about value, relation between value, accumulation of capital and economic development. The Solow's model of growth, its criticism from Cambridge and the expression of production prices, are by turns reexamined. Since the production of commodities can be reduced to a succession of works placed at intervals during the time, Marx has demonstrated that the capitalism can be developped if the work force is exploited and if the surplus of value is invested by the capitalists. Secondly, this paper tries to replace analysis of development in a more large vision of social relations and of their reproduction. By starting from a theory of value which is a theory of social relations and not a microeconomic theory of prices, we arrive to a criticism of accumulation, particularly necessary in the present period of financial accumulation. So, we find again the approach of sustainability of development that we have presented in fore papers.(Full text in French)
