Step-by-step explanation:
The two sectors of the economy in the simple circular flow model are households and businesses. This model highlights the continuous movement of money, resources, and goods and services between these two sectors through different markets.
Essentially, in this model, households provide labor to businesses, and in return, they receive wages, salaries, and benefits. This interaction takes place in the labor market. On the other hand, businesses produce goods and services, which they sell to households in exchange for revenues in the goods and services market.
This dual relationship forms the basis of economic activity in a simplified market economy, showcasing how money and resources circulate within an economy.
