What types of exchanges are shown in the circular flow model?

The circular flow model illustrates two main types of exchanges: the exchange of goods and services between households and firms, and the exchange of factors of production (like labor) for income. Households provide labor to firms in return for wages, while firms produce goods and services that households purchase. This model highlights the interdependence between the two sectors and how money flows in both directions—through spending and income. Additionally, it can include government and foreign sectors, showing taxes, public spending, and international trade.
