The Tableau économique or Economic Table is an economic model first described by François Quesnay in 1759, which laid the foundation of the Physiocrats’ economic theories.
The model Quesnay created consisted of three economic agents: the "proprietary" class consisted only of landowners; the "productive" class consisted of agricultural laborers; the "sterile" class was made up of artisans and merchants. The flow of production and/or cash between the three classes originated with the proprietary class because they owned the land and bought from both of the other classes.
