ABSTRACT
In this chapter an attempt will be made to summarize the main reactions of French socialists when the Marxian theory of value began to be seriously threatened by the rise of marginal economic analysis. The date of 1872 was chosen as the starting point, because Jules Roy translated and edited in French the first volume of Marx’s Kapital between 1872 and 1875. Moreover, this publication date is not far from that of the first edition of Leon Walras’s Elements d’Economie Pure in two volumes between 1874 and 1877. We took the year 1914 as the end of our period since the content of French socialism changed sharply after World War 1.
