Circular Flow of Income
- Circular flow of income is the unending flow of production, income, and expenditure between sectors of an economy.
- Income circulates continuously - firms pay factor incomes to households, and households spend that income back on goods and services produced by firms.

Circular Flow of Income
CBSE: Class 12
Simple Two-Sector Economy (Basic Model)
This model involves only two sectors: Households and Firms, with the following assumptions:
- No government
- No foreign trade
- No saving - households spend their entire income on goods and services.
How It Works
- Firms pay factor payments to households → wages, interest, profit, rent.
- Households spend all income back on goods and services from firms.
- This creates a continuous, circular movement of income.

Three Methods of Measuring National Income
The same aggregate income can be measured at three different points in the circular flow:
| Method | Measured As |
|---|---|
| Product Method | Total value of final output produced |
| Income Method | Total factor payments made (wages + interest + profit + rent) |
| Expenditure Method | Total expenditure on final goods and services |

Three Phases of Circular Flow
| Phase | Description |
|---|---|
| Production Phase | Goods and services are produced by firms. |
| Income Phase | Factor incomes (wages, rent, interest, profit) are paid to households. |
| Expenditure Phase | Households spend income on goods and services. |

Four Sectors of the Economy
In the complete model (beyond the basic two-sector), four sectors participate:
- Household Sector
- Producing Sector (Firms)
- Government Sector
- Rest of the World

Real Flow vs. Money Flow
| Type | What Flows |
|---|---|
| Real Flow | Physical flow of factor services (labour, capital, land, enterprise) and goods/services between sectors. |
| Money Flow | Monetary payments made in exchange for those factor services and goods. |
National Testing Agency: Class 12
Leakages and Injections
| Leakages (Withdraw from Flow) | Injections (Add to Flow) |
|---|---|
| Savings | Investment |
| Taxes | Government Spending |
| Imports | Exports |
- Leakages reduce the flow of income circulating in the economy.
- Injections increase the flow of income circulating in the economy.

Key Points: Circular Flow of Income and Methods of Calculating National Income
- Circular flow = unending flow of production → income → expenditure between sectors.
- In a two-sector economy (no govt., no foreign trade, no saving): firms pay factor incomes → households spend all income back on goods.
- National income can be measured equally by the product, income, or expenditure method - all three give the same result in the simplified model.
- Three phases: Production → Income → Expenditure.
- Real flow = physical movement of goods/factor services; Money flow = monetary payments for those goods/services.
- Leakages (savings, taxes, imports) withdraw from the flow; Injections (investment, govt. spending, exports) add to it.
- Four sectors in the full model: Households, Firms, Government, and Rest of the World.
