What does the circular flow of income model primarily depict?

The circular flow of income model primarily illustrates the flow of income and expenditure in an economy, highlighting how money moves between different sectors, primarily households and businesses. In this model, households provide factors of production, such as labor, to businesses, which in turn produce goods and services. Households spend income earned from these factors on consumption, creating a cycle that shows the interdependence between consumption and production in an economy.

This model is essential for understanding how economies function at a macro level, emphasizing that every transaction between consumers and producers gives rise to new expenditure, thereby generating income. It allows for the examination of how flows of money, goods, and services circulate and contribute to total economic activity.

While the relationships between production and distribution, mechanisms of government spending, and roles of businesses and households in savings are all significant economic concepts, they do not fully encapsulate the comprehensive nature of income and expenditure flows represented in the circular flow model.
