The circular flow of income refers to the continuous flow of goods, services, and money among households, businesses, and the government in an economy. This flow illustrates how these different economic agents are interdependent and rely on each other for their economic well-being. Households provide factors of production such as labor and capital to businesses, which use these factors to produce goods and services. The households, in turn, purchase these goods and services from businesses, generating revenue for the businesses. The government also plays a role in this flow, collecting taxes from households and businesses, and using that revenue to provide public goods and services. The circular flow of income is an important concept in macroeconomics and helps to explain how the overall economy functions.
