(A) Meera and Shahid are two classmates, who were comparing India's economic growth over the years. Meera referred to the increase in Gross Domestic Product (GDP) at current prices prevailing in market, while Sahid insisted on considering GDP after adjusting for inflation. Their debate on which of the two measures gives a true picture of people's well-being, remained inconclusive. Considering the above mentioned situation, elaborate with valid reason, which of the two variables is considered a better indicator of welfare and why ?
OR
(B) Two friends, Ravi and Harry were discussing whether the money received from sale of an old car should be included in India's National income. Ravi was of the view that it should be included in India's National income while Harry did not agree with him. They also had difference of opinion on the treatment of brokerage paid to the car dealer. As their Economics teacher, state the treatments with valid arguments.

(A) GDP at constant prices (Real GDP) is the better indicator of welfare.
GDP at current prices (Nominal GDP, Meera's measure) can rise purely because prices have gone up, without any actual increase in the quantity of goods and services produced. This gives a misleadingly rosy picture of well-being. GDP at constant prices (Real GDP, Shahid's measure) removes the effect of inflation and reflects the true change in physical volume of output, so a rise in Real GDP genuinely means more goods and services are available to people — a real improvement in welfare.
(B) Treatment of the two items
- Sale of the old car — NOT included in national income. It is a sale of a second-hand/used good; its value was already counted as production in the year it was first manufactured. The current transaction is merely a transfer of ownership, not new production.
- Brokerage paid to the dealer — INCLUDED in national income. The brokerage is payment for a current productive service (facilitating the sale) rendered by the dealer in the current year, and hence counts as factor income/value added in this year.
Marking Scheme
- 1Part A: 1 mark for identifying Real GDP (GDP at constant prices) as the better welfare indicator.
- 2Part A: 2 marks for valid reasoning — nominal GDP can rise due to inflation alone without real output increase, while real GDP reflects the actual physical volume of goods/services.
- 3Part B: 1.5 marks for correctly excluding the sale of the old car with reason (value already counted in year of production; mere transfer of ownership).
- 4Part B: 1.5 marks for correctly including brokerage with reason (payment for a current productive service, hence a factor income).
Hint
GDP that adjusts for price changes reflects true output; second-hand sales are excluded but service charges linked to them are included.
Quick Oral Answer
Real GDP is the better welfare indicator since it nets out price-level changes and shows the true rise in output; and while a second-hand car's sale value is excluded from national income, the broker's commission is included as it is a current factor income.
Analysis & Explanation
This question checks whether students can distinguish nominal from real magnitudes, and can correctly separate production from mere asset-transfer.
Part (A) — exam trap: Students often assume 'higher GDP = higher welfare' without checking whether the rise is due to prices or real output. Always state that Real GDP is deflated using a price index (GDP deflator) to strip out inflation.
Part (B) — exam trap: The general rule is 'second-hand sales are excluded, but any current service linked to the sale (brokerage, commission, transportation) is included' because such services represent fresh value addition in the current year, whereas the underlying asset itself was already counted once, in the year it was produced.
Real-world relevance: This is why economists always compare Real GDP growth rates across years/countries rather than Nominal GDP — a country with high inflation can show large nominal GDP growth while its citizens are no better off.
Common Mistakes
- 1Stating that higher GDP always means higher welfare, without distinguishing nominal from real GDP.
- 2Including the entire sale value of the old car in national income instead of only recognising the brokerage as new value addition.
- 3Forgetting to justify WHY brokerage is included (linking it to 'current productive service') and just asserting it without reasoning.
Interesting Facts
The GDP deflator (Nominal GDP/Real GDP × 100) is itself used by economists as the broadest measure of inflation in the economy, wider even than the CPI.
India rebased its GDP series in 2015 (base year 2011-12) precisely to keep Real GDP comparisons meaningful over time.
The exclusion of second-hand sales from GDP is why real estate resale transactions do not directly add to GDP, even though brokerage/registration fees on them do.

Frequently Asked Questions
Why can't Nominal GDP alone measure economic welfare?
Nominal GDP is measured at current market prices, so it can increase simply because prices have risen, even if the actual quantity of goods and services produced remains unchanged or falls — this gives a false sense of improved welfare.
Is the entire amount received from selling an old car ever included in GDP?
No. Only new production in the current year counts toward GDP. Any service charge linked to the resale, like brokerage or commission, is included since it represents current value addition, but the asset's own value is not counted again.
