Overview
This lecture covers the circular flow of the economy for Grade 12 Economics, focusing on participants, flows of goods and money, public goods, injections, withdrawals, different markets, and exam-style questions.
Participants in the Circular Flow
- Four main participants: households (consumers), businesses (firms), government (state), and the foreign sector (trade partners).
- Households buy goods/services from product markets and sell factors of production (land, labor, capital, entrepreneurship) to factor markets.
- Businesses buy factors from households, produce goods/services, sell to households, pay taxes, and may receive subsidies.
- Government provides public goods to households and subsidies to businesses, collecting taxes from both.
- Foreign sector engages in imports (goods to product market) and exports (goods from product market).
Real Flow and Money Flow
- Real flow: movement of physical goods, services, and factors of production (not money).
- Money flow: movement of money, such as wages, payments for goods/services, and taxes.
- Real flows represent economic resources; money flows represent income and expenses.
Injections and Withdrawals (Leakages)
- Injections add money to the economy: investments (by businesses), government spending, and exports.
- Withdrawals remove money: savings, taxes, and imports.
- If withdrawals exceed injections, national income decreases.
Types of Markets in the Circular Flow
- Product Market: where goods and services are sold.
- Factor Market: where factors of production are traded for wages, rent, interest, and profit.
- Financial Market: includes money market (short-term funds) and capital market (long-term investment).
- Foreign Exchange Market: currency is traded for imports/exports.
Public Goods
- Public goods (e.g., free healthcare, education) are provided by the government for all; it's not possible to exclude individuals.
Exam Tips and Example Questions
- Two flows in an open economy: real flow and money flow.
- Participants owning factors of production: households.
- Examples of public goods: free education, healthcare, housing.
- If injections < withdrawals, national income falls.
- Decreased taxes increase income, demand, and production.
Key Terms & Definitions

- Households — Consumers who own and sell factors of production.
- Businesses (Firms) — Producers that buy factors, make goods/services, and sell them.
- Government (State/Public Sector) — Provides public goods, collects taxes, and supports businesses.

- Product Market — Where goods/services are traded.
- Factor Market — Where factors of production are traded.
- Public Goods — Goods/services provided by government, accessible to all.
Action Items / Next Steps
- Review notes on circular flow participants, flows, and markets.
- Practice essay questions on markets and the impact of injections.
- Prepare for term test on macroeconomics, focusing on real and money flows, markets, and public goods.
