National Income Accounting — Practice

Question 1

From the following data, calculate (i) GNP at MP and (ii) National Income (NNP at FC). GDP at MP = ₹5,000 crore. NFIA = ₹200 crore. Depreciation = ₹300 crore. Net Indirect Taxes = ₹150 crore.

Accepted Answer

(i) GNP at MP = GDP at MP + NFIA = ₹5,000 + ₹200 = ₹5,200 crore. (ii) National Income = NNP at FC = GNP at MP − Depreciation − Net Indirect Taxes = ₹5,200 − ₹300 − ₹150 = ₹4,750 crore. Step-by-step: Start with GDP at MP (₹5,000) → add NFIA to get GNP at MP (₹5,200) → subtract Depreciation to get NNP at MP (₹4,900) → subtract NIT to get NNP at FC = National Income (₹4,750).

Question 2

Using the value-added method, calculate GDP from the following data for a simple economy: Farmer sells wheat to miller for ₹200. Miller sells flour to baker for ₹350. Baker sells bread to consumer for ₹500. Also, the baker buys electricity worth ₹20 from the power company, which is not included above.

Accepted Answer

The value-added method sums GROSS VALUE ADDED at each stage, avoiding double counting. Farmer: Sells wheat ₹200. No intermediate inputs (uses own land). GVA = ₹200. Miller: Sells flour ₹350. Intermediate input = wheat ₹200. GVA = ₹350 − ₹200 = ₹150. Baker: Sells bread ₹500. Intermediate inputs = flour ₹350 + electricity ₹20 = ₹370. GVA = ₹500 − ₹370 = ₹130. Power Company: Sells electricity ₹20. Assume no intermediate inputs. GVA = ₹20. GDP (Value-Added Method) = ₹200 + ₹150 + ₹130 + ₹20 = ₹500. VERIFICATION: This equals the value of the FINAL GOOD (bread, ₹500) — as it should. The GDP is ₹500 crore.

Question 3

Explain the limitations of GDP as a measure of economic welfare. Why might two countries with the same GDP per capita have very different standards of living?

Accepted Answer

GDP AS AN IMPERFECT WELFARE MEASURE: GDP (Gross Domestic Product) measures the total monetary value of all final goods and services produced in an economy in a year. It is the most widely used measure of economic size and growth. But it is a deeply imperfect measure of WELFARE — how well people actually live. LIMITATION 1 — NON-MONETARY ACTIVITIES EXCLUDED: GDP only counts transactions involving money. It EXCLUDES: household work (cooking, childcare — performed by millions of women in India, adding enormous value but unpriced), volunteer work, subsistence farming (consumed directly by the farm family). A country where most families buy meals from restaurants will have a higher GDP than one where families cook at home — but their welfare might be similar. LIMITATION 2 — INEQUALITY IGNORED: GDP per capita is an AVERAGE. It hides extreme inequality. India's GDP per capita is ~$2,500 — but this average includes both billionaires and subsistence farmers. Two countries can have the same GDP per capita with vastly different income distributions (one highly equal, one with extreme inequality). The poorer half may be far worse off in the more unequal country. LIMITATION 3 — ENVIRONMENTAL DAMAGE NOT SUBTRACTED: GDP COUNTS activities like oil spill cleanup (which is spending — so it adds to GDP!) while NOT subtracting the environmental damage the spill caused. Deforestation adds to GDP (timber sold). The loss of forest ecosystem services (water regulation, biodiversity) is not subtracted. This means GDP can RISE as environmental quality DETERIORATES. LIMITATION 4 — QUALITY OF LIFE NOT CAPTURED: Leisure time, mental health, political freedom, social trust, safety — none of these appear in GDP. A country that forces 80-hour work weeks will have higher GDP but lower quality of life. LIMITATION 5 — EXTERNALITIES: Pollution is a NEGATIVE externality — it harms health and environment, but these harms are not subtracted from GDP. A factory that pollutes a river adds its output to GDP; the medical costs of sick people living downstream also add to GDP. ALTERNATIVES: Human Development Index (HDI) — combines income, education, and health. Green GDP — adjusts for environmental costs. Gross National Happiness (Bhutan). These attempt to measure welfare, not just production. CONCLUSION: GDP is the best single measure of economic ACTIVITY — but as Robert Kennedy said in 1968: 'GDP measures everything except that which makes life worthwhile.'
