GDP and Welfare

GDP indicates growth in measured economic production, while access to clean water is an important social and public-health indicator. Better water access can reduce disease, improve sanitation, support school attendance, and raise living standards. When both indicators improve, it is reasonable to infer that economic growth may be accompanied by better quality of life, although one indicator cannot prove every aspect of welfare. Therefore, A is the appropriate answer.

Per capita income is calculated by dividing total income by total population. Therefore, ₹15,000 crore ÷ 10 crore = ₹1,500 per person. The crore units cancel because both amounts use crore. Option B is correct; ₹1,000 and ₹15,000 use incorrect calculations, while ₹1,50,000 results from multiplying instead of dividing.

GDP measures the market value of final goods and services, but it does not fully reflect health or environmental quality. If pollution lowers life expectancy while output rises, production has increased but an important aspect of welfare—health—has deteriorated. Therefore, option C is correct.

A product of better quality at the same price can give consumers greater satisfaction, even if recorded spending and measured GDP do not rise. Thus consumer welfare can improve without an increase in measured GDP, making option D correct.

More rural health centres can bring medical advice, treatment, and preventive services closer to residents, reducing barriers such as travel distance. Better access can support improved health and welfare. Therefore, option A is correct; the other outcomes do not follow from expanding health services.

A poor family may not be able to meet essential needs fully. Additional income can help it afford more or better food, housing, and other necessities, so it can make a substantial difference to welfare. Option B gives the relevant reason; the other choices do not explain the value of extra income.

Medical treatment is a service whose market value contributes to measured GDP. But GDP does not fully account for the pain, disability, and loss of quality of life caused by accidents. Thus treatment spending can raise measured output even while welfare is harmed, which is the limitation described in option C.

Average income can rise even when the gains from growth are unevenly shared. A widening rural-urban income gap indicates increasing inequality between the regions. Therefore, option D is correct; the increase in average income alone does not show that all regions benefit equally.

Parks and playgrounds provide spaces for physical activity, recreation, and social interaction. These benefits can support health and well-being, even if they are not fully reflected in GDP. Therefore, option A is correct; the other outcomes do not necessarily follow from adding public spaces.

Real income reflects income's purchasing power after accounting for price changes. If real income does not increase, households cannot necessarily afford more goods and services, even when output rises. Thus improvement in purchasing power may be limited, making option B correct.

Welfare assessment should consider a project’s overall social benefits and costs, not just its output. A dam can provide electricity, but submerging villages may destroy homes, livelihoods and community resources. Comparing these benefits and costs gives a fuller assessment, so option C is correct.

GDP measures the market value of final goods and services, but it does not fully capture children’s leisure, learning or development. If their study and play time falls, their well-being and future opportunities may suffer. Therefore, option D is correct.

Real GDP measures output at constant prices, so it can remain unchanged when the same output is produced in fewer hours. The extra time may be used for leisure or rest, which can improve quality of life. Thus, welfare may rise, making option A correct.

Per capita income is an average monetary indicator, usually calculated by dividing national income by population. It does not capture every aspect of well-being. Reduced access to mental-health care can lower quality of life even when average income rises, so option B is correct.

GDP mainly records the value of production measured through market prices or other accounting methods. Free, non-commercial materials can improve knowledge and skills, but if they have no market price, their educational benefit may not be fully reflected in measured GDP. Therefore, option C is correct.

GDP records the value of current production, but it does not automatically subtract all environmental damage caused by that production. Rising carbon emissions can increase climate risks, pollution and health costs, potentially reducing long-term welfare. Thus, option D is correct.

Inclusive growth means that the benefits of economic expansion reach disadvantaged groups and improve their living conditions. Better access to safe housing for poor families alongside rising GDP may indicate that growth is benefiting a wider section of society. Therefore, option A is correct.

GDP per capita is total GDP divided by population. It can fall if population grows faster than total GDP. For example, if total GDP rises by 3% while population rises by 5%, GDP per capita declines because the population increase outweighs the output increase. Thus, option B is correct.

Automation can raise productivity and total output, but it can also displace workers. If displaced workers cannot quickly find new jobs or receive support, their income and security may decline even as GDP rises. Therefore, option C is correct.

GDP records market activity, including private medical services. If improved public health reduces the need for private treatment, that spending and its contribution to measured GDP may fall. Yet better health can improve quality of life and productivity, so welfare may rise. Therefore, option D is correct.

GDP measures market production, but welfare also depends on people’s health, education, jobs, distribution of income, environmental conditions, and safety. Considering these indicators gives a broader picture than GDP alone. Therefore, B is correct.

The governing concept is that GDP measures the market value of final goods and services, but it is not a complete measure of welfare. If GDP rises while libraries and community centres decline, people may lose access to education, culture, recreation, and social support. Therefore, welfare may decrease despite higher GDP, making option B correct. Options C and D do not logically follow, while A ignores important non-market services.

GDP is more likely to reflect higher economic welfare when the additional output consists of goods and services that genuinely satisfy human needs and when the resulting benefits reach a broad share of the population. A is therefore correct. Rising pollution, greater inequality, defensive expenditure, and declining leisure or health can weaken or reverse the welfare effect even if measured output increases.

GDP primarily represents the value of market production and income, but human welfare also depends on capabilities that income alone cannot fully reveal. Life expectancy indicates an important health outcome, while literacy reflects access to and attainment in education. C is correct because these indicators add non-income dimensions. They do not prevent double counting, stabilise prices, or measure only exports.

GDP can increase because market production and income have expanded, yet it does not guarantee improvement in every component of quality of life. Safe drinking water is a basic health and living-condition indicator; declining access represents a welfare loss even alongside economic growth. D is therefore correct. A is too absolute, B does not follow from a welfare change, and C ignores the direct health importance of safe water.
