Reading the National Income Numbers: GDP, GNP and Welfare Claims
The statistical office of a small open economy releases the following figures for the year, all in ₹ crore: private final consumption expenditure 1,200; government final consumption expenditure 400; gross domestic fixed capital formation 460; change in stocks 40; exports of goods and services 250; imports of goods and services 300; net factor income from abroad −40; consumption of fixed capital 150; net indirect taxes 120; current transfers (remittances) from abroad 90; sale of a second-hand building 60; purchase of shares by residents 25. A newspaper headline reports that 'national income has been computed at ₹2,050 crore'. The finance ministry separately claims credit for an 11% rise in nominal GDP, notes that the GDP deflator rose 5% and that population grew 1.8%, and says living standards have improved for everyone. An opposition member points to the ₹90 crore of remittances and argues they should be added because they are received from abroad.
1. Compute national income from these figures and explain how the remittances, the second-hand building and the share purchase should be treated.

Expenditure build-up. GDP at market prices = C + G + gross capital formation + (X − M) = 1,200 + 400 + (460 + 40) + (250 − 300) = ₹2,050 crore This is the figure the newspaper mislabels as national income: it is domestic product at market prices, gross of depreciation and net of nothing.
GNP at market prices = 2,050 + (−40) = ₹2,010 crore NNP at market prices = 2,010 − 150 = ₹1,860 crore National income (NNP at factor cost) = 1,860 − 120 = ₹1,740 crore
Treatment of the three items.
- Remittances, ₹90 crore: these are current transfers, not payment for a factor service, so they are excluded from net factor income from abroad and hence from national income. The opposition member is wrong for national income but not for welfare: transfers do add to the income households can spend, which is why a separate measure (gross national disposable income) adds them. Accepting them into NNP would also double count, since most of what they finance already appears in consumption.
- Second-hand building, ₹60 crore: not current production, so excluded; only any broker's commission this year would count as a service produced now.
- Shares, ₹25 crore: a financial transaction that merely swaps one asset for another, not production, so excluded from GDP.
Conclusion: the headline overstates national income by ₹310 crore (depreciation plus net indirect taxes plus the negative factor income).
2. The ministry claims an 11% nominal GDP rise proves living standards improved 'for everyone'. Assess that claim using the deflator and population figures, and identify what the national income data cannot show.

Adjusting the claim. Real GDP growth = (1.11 ÷ 1.05) − 1 = +5.71%, not 11% - about 5 percentage points of the headline is price change, not output. Real GDP per person = (1.0571 ÷ 1.018) − 1 = +3.85%
So the defensible statement is that real output per head rose by under 4%, not that nominal income rose 11%. The ministry has used a nominal magnitude and a per-capita welfare conclusion, which are two different measurements.
What the data cannot establish.
- Distribution. A rising average is compatible with most households stagnating if gains are concentrated; national income has no median.
- Depreciation. GDP is gross: part of the 11% may merely replace worn-out capital. NNP grew by less.
- Non-market production. Unpaid household and care work never enters these figures, so an increase in measured output may reflect activity shifting into the market rather than new welfare.
- Composition and externalities. More output of a polluting activity raises GDP while reducing welfare; defensive spending on cleaning up pollution is counted as output, not as a cost.
- Remittances. The ₹90 crore supports spending but is not domestic production, so consumption-based comfort can rise without national income rising.
Judgement for the candidate: use real per-capita NNP or a distribution-aware measure before making welfare statements, and state the price and population assumptions explicitly, because a claim that 'everyone' gained is a distributional claim that aggregate national accounts cannot support.
