GDP and Welfare

The governing concept is a negative externality: production can impose costs on nearby people without a complete market payment to them. Noise may cause stress, poor sleep, reduced concentration, and health damage, so its social cost is not fully recorded in the value of industrial output. Option D is correct. Wages, raw materials, and machinery are ordinary production costs more directly included in market transactions.

The governing concept is per capita GDP, calculated as total GDP divided by population. Here, ₹12,000 crore ÷ 8 crore = ₹1,500 per person; the crore units cancel because both figures use the same unit. Therefore option A is correct. ₹96,000 comes from multiplication, while ₹4,000 and ₹800 do not result from the required division.

The governing concept is that the composition and distribution of output matter for welfare, not merely its total value. If growth is concentrated in luxury goods purchased by rich households, most people may receive little benefit and basic needs may remain unmet. Therefore option B is correct. Final goods are not excluded from GDP, and the question gives no basis for claims about population or imports.

The governing concept is that employment quantity alone cannot measure welfare. Secure contracts, adequate wages, safe conditions, working hours, and social protection influence workers’ living standards. Hence option C is correct: a rise in job numbers may coexist with poor-quality employment. Options A and B ignore job conditions, while option D is unsupported because employment data alone cannot prove that GDP fell.

The governing concept is that GDP records the market value of current final goods and services, not whether the spending arose from a beneficial event. Paid medical treatment and reconstruction generate market transactions and are therefore counted in GDP, so option D is correct. However, this does not mean welfare necessarily rises, because the disaster caused losses, suffering, and destruction that GDP may not fully show.

The governing concept is inclusive welfare: real per capita GDP reflects inflation-adjusted output per person, while lower inequality suggests that gains are distributed more broadly. When both indicators improve, living standards are generally expected to improve for a larger share of the population, making option A correct. The other choices contradict the information or introduce unrelated claims about prices and population.

The governing concept is that public services can improve welfare even when their benefits are not fully represented by direct private purchases. Free libraries expand access to books, information, study space, and learning opportunities, which can build human capabilities and support education. Therefore option B is correct. Exports, population decline, and rising market prices are neither necessary results of libraries nor explanations of their welfare benefit.

The governing concept is that GDP should be considered alongside social and health indicators when assessing welfare. Rising output measures more market production, but sharply higher sick-leave days may signal unsafe workplaces, stress, pollution, or worsening health. Therefore option C is correct. The evidence does not show that every worker is healthy, that GDP is wrongly measured, or that output fell.

GDP measures the market value of final goods and services, but it does not fully capture safety, freedom from fear, or peace of mind. If crime falls while recorded output stays unchanged, people may feel safer and spend less time and money protecting themselves. Therefore, social welfare may increase even though GDP is constant. Options A, B, and C ignore this important non-market improvement.

GDP is calculated mainly from recorded market transactions involving final goods and services. Clean air provides a substantial benefit, but when it is freely available, no buyer normally pays a measurable market price for that environmental service. Consequently, its welfare value is usually omitted from GDP. Option B is unrelated, option C misclassifies air, and option D is false because clean air clearly improves health and well-being.

The relevant concept is diminishing marginal utility of income. An additional unit of income usually gives less extra satisfaction to a rich family than to a poor family that cannot adequately afford food, housing, health care, or education. If redistribution helps the poor meet these necessities, total social welfare can rise even though aggregate income and output remain unchanged. Options A, C, and D do not follow from redistribution.

GDP records the market value of production, so a quantity sold at the same price may contribute the same measured value even when its quality and usefulness improve. Consumers nevertheless receive greater satisfaction, durability, safety, or performance. Because these non-price quality gains are difficult to measure fully, GDP can understate the welfare increase. Option C captures this measurement limitation; the other choices are unsupported.

The governing idea is net social benefit: welfare depends on benefits as well as costs imposed on residents and the environment. Tourism may increase sales, wages, tax revenue, and measured GDP, but waste disposal, traffic delays, noise, pollution, and loss of local amenity reduce welfare. A proper assessment therefore compares the income gains with these external costs and deducts them where possible. Options A–C measure only one benefit.

Infant mortality is a social and health indicator, not a direct measure of exports, inflation, or public debt. A lower rate generally suggests improved nutrition, sanitation, maternal care, medical access, and living conditions. When it falls alongside GDP growth, the evidence points to economic progress being accompanied by a possible improvement in social welfare. Therefore, option A is the only appropriate conclusion.

Per capita GDP is average output or income per person; it does not show how many jobs exist or how income is distributed. If this average rises while unemployment increases, output may be growing through automation, capital-intensive production, or gains concentrated among fewer workers. The appropriate conclusion is that growth may be jobless and may not improve welfare for everyone. Thus B is correct; the other options are extreme or unrelated.

GDP is a flow measure of current production, whereas natural resources such as forests, soil, minerals, and groundwater are part of the productive asset base. Extracting them may raise present output while reducing the economy’s future capacity and imposing environmental costs. Sustainable welfare therefore requires considering resource stocks, depletion, regeneration, and long-term effects, not GDP alone. Option C expresses this intergenerational limitation.

The concept illustrated here is defensive expenditure. Purchases of alarms, locks, cameras, or other security equipment are market transactions and can increase measured GDP. However, the underlying rise in crime creates fear, loss of freedom, and possible harm, reducing welfare. The spending may protect people from some danger but does not make the original insecurity a benefit. Hence GDP may rise while security-related welfare falls, making D correct.

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 capture health, environmental quality, or quality of life. If output rises while pollution lowers life expectancy, economic production has increased but an important component of welfare has deteriorated. Thus option C is correct; the other choices wrongly treat GDP as a complete welfare measure or make an unrelated claim.
