GDP and Welfare

The governing concept is real GDP per capita, calculated as real GDP divided by population. For country A, ₹1,200 crore divided by 20 lakh people equals ₹6,000 per person. For country B, ₹900 crore divided by 10 lakh people equals ₹9,000 per person. Hence country B has the higher real output per person, so option B is correct; comparing totals alone would incorrectly favour A.

GDP mainly records measured market production and government expenditure, whereas welfare includes health, survival, time saved, and the value of services received without a market payment. If clean water is supplied efficiently with little recorded spending, disease may fall substantially while GDP changes only slightly. Option A is correct; B confuses expenditure with welfare, and C and D are plainly unsupported.

GDP applies market prices to measured final output; it does not directly measure the satisfaction, quality, durability, or usefulness consumers obtain from that output. Therefore two economies with equal GDP can provide different welfare when one produces short-lived, low-utility goods. Option A states this limitation. B is false because GDP includes many nondurable goods, while C and D incorrectly equate utility with price.

The governing concept is green accounting: conventional GDP can rise when production creates pollution or depletes forests, minerals, and other natural capital, even though sustainable welfare may decline. Deducting estimated environmental damage and resource depletion gives a measure closer to net green output, so option A is correct. Double-counting taxes, mishandling imports, or adding used-goods sales would not correct this environmental omission.

GDP counts many paid market transactions but generally does not assign the full market value of unpaid voluntary work. If volunteers replace purchased services, recorded expenditure and GDP may decline even though people receive valuable care, support, and community benefits. Thus welfare can improve while measured GDP falls, making option B correct. The words “may” and “actual welfare” prevent the absolute claims in the other options.

The governing identity is real GDP per capita = real GDP divided by population. In growth-rate form, approximately, per-capita GDP growth equals total real GDP growth minus population growth. Therefore population growth is approximately 8% − 2% = 6%. Option B is correct. The exact multiplicative calculation gives a very similar figure, so the approximation is appropriate; 2%, 8%, and 10% confuse one of the given rates or add them incorrectly.

The governing concept is the distinction between nominal value and real output. A rise in rent can increase the money value assigned to housing services without improving their quantity, quality, safety, or comfort. Therefore, welfare analysis should adjust for price changes and examine real services. Option A is correct; B is false because measured rent can enter GDP, while C and D confuse price or one indicator with actual welfare.

GDP measures the value of current production, including many publicly provided services, but it does not judge whether the underlying situation is desirable. More prison spending may reflect increased crime, insecurity, or social distress. Thus the expenditure can raise measured GDP while welfare falls. Option B is correct; A and C incorrectly deny the value of public services, and D assumes an unjustified positive relationship.

The governing concept is that an average is not the same as an equitable distribution. Per-capita income can rise if gains go mainly to richer households, while the incomes of poorer households stagnate or decline relative to the poverty line. Therefore, welfare analysis must examine both average income and distribution. Option A is correct; B denies the relevance of poverty, C is false, and D does not logically follow.

GDP records the value of measured output, not every benefit people receive from production. If technology produces the same output with fewer inputs and working hours, people may enjoy more leisure, lower resource pressure, and reduced costs. These benefits can raise welfare even without higher GDP. Option A is correct; B ignores non-market benefits, C is too narrow, and D confuses leisure with counted income.

The governing concept is that welfare is multidimensional. Real GDP per capita indicates average purchasing power or production, but it does not fully measure political rights, personal safety, dignity, equality, or freedom from fear. Consequently, high income cannot automatically establish high welfare. Option B is correct; A overstates the power of income, C denies an important welfare factor, and D falsely claims complete GDP coverage.

The governing idea is that net welfare should consider both the benefits of output and the external costs created during production. A 5% real-output gain does not guarantee a welfare gain when pollution costs rise by an estimated 7% of output; the net effect may be negative, although exact welfare requires careful measurement. Option B is correct. A ignores costs, C denies externalities, and D incorrectly adds percentages.

GDP generally records market production, whereas unpaid household services are often outside measured GDP. When the same childcare activity moves from unpaid family work to a paid centre, measured market output and GDP can rise even if the amount and quality of care do not change. Option A is correct. B misclassifies the service, C makes an unjustified welfare claim, and D contradicts the treatment of paid final services.

Overall welfare is multidimensional, so no single economic total is sufficient. Real GDP per capita helps compare real average output after allowing for prices and population, while distribution, health, education, environmental quality, and leisure capture important aspects omitted by GDP. Option B is therefore the most suitable combination. A, C, and D each use only one limited indicator and cannot represent total welfare.
