What is circular flow of national income?
Show model answer
The circular flow of national income shows the continuous flow of money, goods and services between households and firms. Households supply factors of production (land, labour, capital, entrepreneurship) to firms and receive factor payments (rent, wages, interest, profit) in return; firms use these to produce goods/services sold back to households, who spend their income on them. This forms a continuous circular flow — an inner loop of real goods/factor services and an outer loop of matching money payments — which repeats endlessly through the economy.
