Note 765 — Chapter II · : THE APOGEE AND DECLINE OF THE CLASSICAL SCHOOL. JOHN STUART MILL
R. (Robert) Richards translation
“The rise or the fall continues until the demand and supply are again equal to one another: and the value which a commodity will bring in any market is no other than the value which in that market gives a demand just sufficient to carry off the existing or expected supply.” (Principles, Book III, chap. 2, § 4.)
Cournot in his criticisms of the law of demand and supply had anticipated Mill. But it is very probable that Mill was not acquainted with the Recherches.
