MENGER, JEVONS AND WALRAS DE-HOMOGENIZED

In this essay, emphasis is laid on the differences between the "revolutionary" innovations of Menger, jevons and Walras. The main point is that the persistent historiographic practice of classifying these authors together simply as independent discoverers of very much the same marginal utility principle has obscured essential differences not only in the original intent and design of their theoretical edifices, but also in the influence their major works exerted, each in a way of its own, upon the subsequent development of economic thought.
