| | Phases of the Marginalist Revolution |
 | | The idea of a demand function itself was proposed by Charles D'Avenant (1699), who even attempted to estimate one for wheat (on the basis of data allegedly provided by Gregory King (1696)). |
 | | This, of course, was not all: in addition to demand functions, Cournot introduced the concepts of marginal revenue, marginal cost, the concept of the profit-maximizing firm, monopoly, duopoly, perfect competition and, of course, his famous "reaction functions". |
 | | Marginal utility, let us be frank, is hardly a scientific concept: unobservable, unmeasurable and untestable, marginal utility is a notion with very dubious scientific standing. |
