* Wikipedia: The Wikipedia entry on "Circular Flow of Income" provides a concise overview of the concept and its assumptions.
Specific Assumptions:
* Two-sector model: The basic model typically assumes only two sectors: households and firms.
* Closed economy: The model often ignores international trade, focusing solely on internal transactions within the economy.
* No government intervention: The simplest model assumes no government spending, taxes, or transfer payments.
* No savings or investment: The model may initially ignore these factors, assuming all income is spent on consumption.
* Full employment: The model typically assumes that all resources are fully employed, with no unemployment or unused capacity.
Beyond the Basics:
Once you understand the basic circular flow model, you can explore more complex versions that incorporate:
* Government: Including government spending, taxes, and transfer payments.
* International trade: Accounting for exports and imports.
* Savings and investment: Recognizing how savings lead to investment and capital formation.
* Leakages and injections: Examining how factors like savings, taxes, and imports withdraw funds from the circular flow, while investment, government spending, and exports inject funds back in.
By understanding the assumptions and limitations of the circular flow of income model, you can appreciate its value as a simplified framework for understanding the complex interactions within an economy.
