Who propounded the theory of the circular flow?

Answer 1

The theory of circular flow was primarily propounded by economists such as François Quesnay in the 18th century, who introduced the concept through his "Tableau Économique." This model illustrated the flow of goods and services between different sectors of the economy, emphasizing the interdependence of households and businesses. Later economists, including John Maynard Keynes, expanded upon this idea, integrating it into broader economic theories.
