GDP and Welfare

Correct answer: B. जब अपुनर्नवीकरणीय संसाधनों का तीव्र क्षय हो

The governing concept is sustainability: current production should not undermine the resources and environmental conditions needed by future generations. Rapid depletion of non-renewable resources may raise current GDP through extraction, yet reduce future productive capacity and welfare. Therefore option B is correct. Renewable energy, education investment, and forest conservation generally strengthen long-term welfare when managed effectively.

Correct answer: C. क्योंकि बाजार व्यय बढ़ सकता है जबकि सुरक्षा और स्वास्थ्य बिगड़ते हैं

GDP measures market production and expenditure, so purchases of alarms, security equipment, or medical treatment may increase measured output. However, that spending can be a defensive response to crime and does not represent an improvement in safety or health; it may merely repair social harm. Thus option C is correct. Options A and D incorrectly exclude valued services, while B is an absolute and false claim.

Correct answer: D. सकल घरेलू उत्पाद बढ़ सकता है, लेकिन जीवन गुणवत्ता घट सकती है

GDP counts the value of market production but does not directly assign a monetary value to lost leisure or the stress associated with longer working time. Consequently, output can rise while people’s non-market well-being and quality of life decline. Option D is correct. A assumes GDP and welfare always move together, B denies the value of leisure, and C contradicts the stated increase in output.

Correct answer: A. Welfare may rise while GDP remains nearly unchanged

GDP mainly records the market value of final goods and services exchanged for money. Volunteer medical camps can improve health, prevent suffering and increase welfare, yet their unpaid services may not be fully included in measured GDP. Therefore, welfare can rise even when market output is almost unchanged. Options B and C use unjustified words such as “must,” while D wrongly denies the social value of unpaid work.

Correct answer: B. Because marginal utility of income may be higher for low-income groups

Real GDP measures the volume of aggregate production, not how that production income is distributed. Under the diminishing marginal utility of income, an additional rupee generally gives greater satisfaction to a low-income household than to a rich household. If income shifts toward the rich while total output stays fixed, the loss of utility among poorer people may exceed the gain among richer people. Thus B is correct; A, C and D contradict the situation.

Correct answer: C. Because it separates the effect of price changes

Nominal GDP values current production at current prices, so it can increase merely because prices have risen. Real GDP values production using constant or base-year prices and therefore focuses more closely on changes in the quantity of output. This makes comparisons across years more meaningful for welfare analysis, although real GDP still does not fully capture distribution, unpaid work or environmental quality. Hence C is correct.

Correct answer: D. GDP may rise while safety-related welfare declines

Government-provided prison services are counted in GDP through the cost or value of public production. However, if spending rises because crime has increased, the expenditure may be defensive: it responds to damage or insecurity rather than representing an improvement in people’s lives. GDP can therefore rise while safety and welfare deteriorate. B is factually incorrect, and A, C ignore the reason and social cost behind the spending.

Correct answer: A. Economic output and human welfare can move in opposite directions

Real per capita GDP indicates average inflation-adjusted output or income per person, but it is not a complete measure of human well-being. Life expectancy reflects an important health outcome. If the average economic indicator rises while life expectancy declines, the two outcomes show that production and welfare can move in opposite directions. B dismisses health, C is not logically necessary, and D cannot be inferred from an average increase.

Correct answer: B. GDP may rise but welfare may fall because of time loss and pollution

Fuel purchased for longer commuting is a market transaction and can add to measured GDP, provided it represents counted final expenditure. Yet longer travel consumes time that could be used for leisure or family activities, and extra fuel use can create congestion and pollution. These external and non-market costs may reduce welfare even as market sales increase. Therefore B is correct; A is too absolute, while C and D are false.

Correct answer: C. Useful and harmful goods of equal value may have different welfare effects

GDP aggregates the monetary value of final goods and services, but equal monetary values do not imply equal social benefits. Education, nutritious food or preventive care may improve capabilities, whereas pollution-generating or harmful goods may impose social costs. Consequently, the composition and purpose of production matter for welfare, not merely its total value. C states this distinction accurately; A, B and D incorrectly treat all output as socially equivalent.

Correct answer: D. Timber value is added but loss of forest wealth is not fully deducted

When timber is sold, the value of the recorded market production is added to GDP. Ordinary GDP, however, generally does not deduct the full depletion of the forest as a natural asset or the lost ecological services, such as biodiversity and carbon absorption. Thus measured output may rise even while national wealth and environmental welfare decline. D correctly describes this limitation; A, B and C deny the relevant accounting issue.

Correct answer: B. Because higher spending may result from greater illness

Paid healthcare services and medicines are generally included in GDP, so pandemic-related medical expenditure can raise measured output. But the spending may have increased because more people became ill, not because they became healthier or better off. GDP records the value of the response, while it does not automatically show the underlying loss of health or the suffering caused by disease. Therefore B is correct; A and D are false, and C is unsupported.

Correct answer: C. When income growth is concentrated in a very small high-income group

Per capita GDP is an average: total real GDP is divided by population. A small group with exceptionally large income gains can raise the average even if the majority experience falling real incomes. This is the limitation of using an average without examining distribution and household-level data. C describes that situation. Equal income growth, broad employment growth and falling prices would generally support, rather than imply, a fall in most households’ real income.

Correct answer: D. The value of previously non-market services begins to be recorded in the market

The governing concept is the coverage of national income accounting. Unpaid household work may provide real services, but its imputed value is generally excluded from measured GDP. When the same activity is purchased in the market, a recorded payment and market value enter GDP, even if the physical service has not increased. Therefore D is correct; the other choices claim effects that are not necessary.

Correct answer: A. When useful output rises and benefits are broadly distributed

GDP is more likely to reflect economic welfare when its increase represents useful goods and services and the resulting gains reach a broad share of the population. Thus A is correct. Rising pollution, greater inequality, reduced leisure, or spending caused by accidents can raise measured GDP while weakening quality of life, so B, C, and D do not strengthen the relationship.

Correct answer: B. Net welfare improvement may be doubtful or negative

The governing idea is that GDP records gross market output, not every social cost. A 4% rise in real GDP shows greater inflation-adjusted production, but a 6% rise in environmental damage can offset or exceed the associated benefit. Hence B is correct: net welfare improvement is uncertain and could be negative. A ignores costs, while C and D are false.

Correct answer: C. They show non-income dimensions of health and education

GDP mainly indicates the monetary value of final goods and services, so it does not fully describe human development. Life expectancy supplies information about health, while literacy reflects educational achievement and capability. Therefore C is correct: these indicators add important non-income dimensions. They do not primarily prevent double counting, stabilise prices, or measure only trade.

Correct answer: D. A basic aspect of quality of life worsened despite economic growth

The governing concept is the distinction between economic growth and broader welfare. GDP can increase because more market output is produced, yet reduced access to safe water harms health, security, and basic living conditions. Thus D is correct. A wrongly treats GDP growth as proof of welfare growth; B is not established by the information; and C ignores a basic welfare requirement.

Correct answer: A. Only the commission for the broker's current service

GDP measures current production within the accounting period. The old house was produced in an earlier period, so its resale value is not counted again as current output; otherwise there would be double counting. However, the broker provides a new service during the current period, and the commission is payment for that service. Therefore A is correct, not B, C, or D.

Correct answer: B. Broad income security may not improve despite higher output

Jobless growth means measured output rises without a comparable expansion of employment. Since many households depend on labour income, higher GDP may fail to provide them with earnings, security, or improved purchasing power. B is therefore correct. A assumes equal gains without evidence, C contradicts the meaning of jobless growth, and D wrongly dismisses distribution as a welfare concern.

Correct answer: C. Vaccination reducing infection in the community

A positive externality exists when an activity creates benefits for third parties that are not fully reflected in the buyer's private payment. Vaccination protects the recipient and lowers the probability of infection for other community members, so its social benefit exceeds its private market valuation. C is correct. Smoke and deforestation create negative externalities, while crime-related security spending does not represent this positive spillover.

Correct answer: D. GDP may rise while worker welfare declines

GDP records the value of current market production, but it does not automatically adjust for pain, injury, lost safety, or reduced quality of working life. If output rises while workplace accidents increase sharply, production may expand even as workers face greater health and personal costs. D is correct. The other choices wrongly treat output growth as a complete welfare measure or deny accident costs.

Correct answer: A. Welfare may rise even if fuel sales decline

Market sales are only one part of welfare. Better public transport can reduce private fuel purchases while saving commuters' time, lowering congestion, and possibly reducing pollution. These benefits may improve well-being even if one component of market expenditure falls. A is therefore correct. B and D ignore the value of time and public benefits, while C incorrectly claims GDP and welfare always move together.

Correct answer: B. It may hide the low income of the majority behind an average

Per capita GDP is calculated by dividing total GDP by population, so it gives only an average income or output figure. It does not show how income is distributed among households. If the richest five percent receive a very large share, their high incomes can raise the average while most people remain poor. Therefore, option B is correct; the other options confuse distribution with output, population counting, or prices.

Correct answer: C. The full value of the quality improvement may not appear in GDP

Many non-market government services are valued in national accounts using their cost of production, such as wages and operating expenses. If the service becomes better but its measured cost does not change, the improvement may not increase recorded GDP proportionately. Thus option C is correct. Option A is too absolute, B is false because public services are included, and D does not necessarily follow.
