Circular Flow of Income Model

Circular Flow of Income

The circular flow of income is a model that illustrates the flow of income and expenditures between different sectors of an economy.

Key Sectors:

• Households: Provide factor services (labor, entrepreneurship, capital) to firms and receive income in the form of wages, rent, and profits.
• Firms: Produce goods and services using factor services, and sell them to households.
• Government: Collects taxes from households and firms, and provides public goods and services.
• Rest of the World: Represents foreign countries that trade with the domestic economy.

Flows of Income:

• Factor Income: Households receive income from firms for their factor services (labor, entrepreneurship, capital).
• Goods and Services: Firms sell goods and services to households, generating revenue.
• Taxes: Households and firms pay taxes to the government.
• Government Expenditures: Government spends on public goods and services, and transfers to households and firms.
• Imports and Exports: Trade between the domestic economy and the rest of the world.

Leakages and Injections:

• Leakages: Savings, taxes, and imports that reduce the flow of income.
• Injections: Investments, government expenditures, and exports that increase the flow of income.

Equilibrium:

• The circular flow of income is in equilibrium when the total value of leakages equals the total value of injections.
• Equilibrium is achieved when aggregate demand equals aggregate supply.

Importance of the Circular Flow of Income:

• Helps understand the interconnectedness of different sectors of the economy.
• Illustrates the flow of income and expenditures between sectors.
• Enables analysis of the impact of economic shocks and policy changes on the economy.
