ABSTRACT
Francois Quesnay points out that any change in the proportion of income spent on luxuries by the several social classes is bound to affect the total annual revenue for better or for worse. Actually Marquis de Mirabeau himself produced a more satisfactory account of economics, and so did Anne Robert Jacques Turgot, another member of the physiocratic circle, both of whom, no doubt, owed much to Quesnay. Mirabeau was energetic, enthusiastic, and a vivacious propagandist who gained many converts, made physiocratic economics known all the world over, and took a very active part in the work connected with the earliest periodicals devoted to economic and social problems, namely the Journal de l’Agriculture and the Ephemerides. As will have been seen from the foregoing account, Richard Cantillon, Mirabeau, and Turgot, to say nothing of others, produced systematic treatises on economics of considerable merit.
