While estimating National Income through the Expenditure Method, the following precautions must be taken:
1. Avoid Double Counting:
- Only final expenditure should be included, excluding intermediate goods and resale transactions.
2. Exclude Transfer Payments:
- Payments such as pensions, scholarships, and social security benefits should not be counted, as they are not part of actual production.
3. Include Imputed Values:
- The value of self-consumed goods, owner-occupied houses, and free public services should be estimated and included.
Conclusion:
Proper precautions ensure accurate measurement of national income and prevent overestimation or underestimation.
