GDP and Welfare

NDP records the value of measured domestic production after deducting depreciation, but it may not fully subtract every environmental cost caused by production. If a polluting industry expands, NDP can increase even as health, environmental quality, and people’s quality of life deteriorate. Thus, the net welfare effect cannot be determined from the rise in NDP alone.

The income method measures NDP at factor cost by adding the factor incomes generated in domestic production: compensation of employees, operating surplus and mixed income. Hence NDP at factor cost = 1,300 + 780 + 420 = 2,500 crore rupees. Option B is correct. The other choices reflect incomplete addition or an unjustified extra amount; no depreciation or net factor income adjustment is required for this stated aggregate.

The governing welfare measure is per-capita NDP, calculated as total NDP divided by population. Total NDP can rise while population grows at a faster rate; in that case, NDP per person falls and average material availability may decline. Therefore option A is correct. The other choices are not necessary conditions: depreciation need not be zero, exports need not stop, and taxes ending does not logically explain a lower per-capita output.

The governing relationship is GDP = NDP + depreciation, because NDP is obtained after deducting consumption of fixed capital from GDP. Since both countries have the same NDP, the country with greater depreciation will have the greater GDP after it is added back. Therefore, the first country is correct. Equal NDP alone does not imply equal GDP when depreciation differs.

Government schooling is generally a non-market service because it is not sold at a normal market price to students. In national accounting, such services are valued by their cost of production, especially the compensation paid to employees such as teachers, along with relevant operating costs. Thus option B is correct. Fees, building value and examination results do not measure the current flow of teaching service.

Per-capita NDP is an average: total NDP divided by population. An equal average can hide very different income distributions; one country may have greater inequality while the other distributes income more broadly. Welfare also depends on access to health care, education, public safety, leisure, and environmental quality, which the aggregate does not fully measure. Currency names, flags, and census dates do not directly determine welfare. Hence option A is correct.

Conventional NDP can record the value of production without fully subtracting environmental damage. So it may rise by ₹850 crore even as environmental costs reduce welfare. If the two amounts are comparable and the damage is counted, the net change after this cost is ₹850 crore − ₹1,100 crore = −₹250 crore. Option A is the appropriate conclusion.

Net indirect taxes are defined as indirect taxes minus subsidies: NIT = IT − S. Let indirect taxes and subsidies be 5x and 2x respectively. Their difference is 3x = ₹150 crore, so x = ₹50 crore. Therefore, indirect taxes = 5x = 5 × 50 = ₹250 crore. Option C is correct. ₹100 crore represents neither the stated tax amount nor the required ratio, while ₹375 crore incorrectly treats the full ratio total as the tax.

Use NIT = indirect taxes − subsidies. With the ratio 3:5, let taxes = 3x and subsidies = 5x. Then NIT = 3x − 5x = −2x. Since NIT is −₹80 crore, −2x = −80, giving x = ₹40 crore. Subsidies are therefore 5x = ₹200 crore, so option C is correct. The other choices do not preserve both the 3:5 ratio and the negative net amount.

Real GDP measures the market value of final goods and services produced, adjusted for price changes. It does not fully include pollution, resource depletion, leisure, inequality or other non-market aspects of well-being. Thus, production can rise while environmental costs increase. Option A is correct; this limitation does not make real GDP useless or always incorrect.

Real GDP measures the total volume of production, not how income or output is distributed among households. If most gains go to a small group, average or total GDP can rise while many people experience little improvement in income or living conditions. Option A is correct. The other choices claim facts that cannot be inferred from aggregate real GDP alone.

Real GDP is useful because it measures the value of domestic output at constant prices, thereby removing much of the effect of inflation. However, welfare also depends on how income is distributed, unpaid household work, leisure, environmental quality, health and safety. Real GDP does not fully capture these dimensions. Therefore option B is correct; A, C and D contradict the meaning or use of real GDP.

Real GDP per capita is calculated as real GDP divided by population. Initially it is 500 ÷ 100 = 5. In the later period it is 550 ÷ 115 ≈ 4.78. Although total real GDP increased by 10%, population increased by 15%, so output per person declined. Therefore option B is correct; total GDP growth alone does not guarantee higher per-capita output.

Real GDP isolates changes in production by valuing output at constant base-year prices. Thus, negative real GDP growth means that the quantity of final output decreased. Nominal GDP, however, reflects both quantities and current prices. If prices rise sufficiently, their increase can outweigh the fall in output, making nominal GDP grow. Therefore, a fall in output together with sufficiently higher prices makes option A possible and correct.

Real GDP is designed to measure the quantity of final goods and services produced, with the effect of price changes removed. Economic welfare is broader than production: it also depends on how income is distributed, unpaid household work, leisure, environmental quality, health and security. Thus option B is correct. Option C is false because constant prices are used, while D is false because final goods are included.

Real GDP values current-year quantities at base-year prices, so it removes the effect of current price changes. For rice, the value is 40 units × ₹30 = ₹1,200. For milk, it is 20 units × ₹50 = ₹1,000. Adding the two values gives real GDP of ₹2,200. Therefore, option C is correct. Using current prices instead would calculate nominal GDP, not real GDP.

Real GDP measures the market value of final goods and services produced, adjusted for prices, but it is not a complete measure of welfare. A rise in GDP can coexist with greater income inequality, pollution, resource depletion, congestion, or stress. If the gains are concentrated and environmental costs increase, many people may be worse off even though measured real output rises. Therefore option A is the valid reason.

GDP measures production using market values, so the extra benefit users receive from a free service—such as convenience or enjoyment—is not fully captured as consumer welfare. The service’s production may still be counted if it has market-valued revenue or costs, but that does not measure the full benefit to users. Thus A is correct.

Reconstruction spending represents newly produced construction and repair services, which can raise measured GDP. But GDP does not subtract all the damage caused by the disaster, such as destroyed homes, infrastructure, or lost well-being. A rise in GDP therefore does not prove that all social losses were offset. B is correct.

Real GDP measures current production using base-year prices, thereby removing the effect of current price changes. For the first good, the value is ₹12 × 80 = ₹960. For the second, it is ₹25 × 24 = ₹600. Adding these values gives real GDP = ₹960 + ₹600 = ₹1,560. Hence option C is correct; using current prices or adding the inputs incorrectly would produce the other figures.

Real GDP measures the volume of final goods and services using constant prices, so it removes much of the effect of inflation. However, total real GDP does not show how output is distributed, how population has changed, or whether the average person is better off. Per-capita real GDP and distributional, social and environmental indicators are therefore needed. Option A is correct; the other statements contradict what GDP measures.

Real GDP is an indicator of market-valued production at constant prices, not a complete measure of welfare. Leisure has value, and a sharp loss of leisure may reduce well-being even when market output rises. Without information about the size of the leisure loss, distribution, health, environment and other factors, no definite welfare conclusion follows from real GDP alone. Thus C is correct; A and B are unjustified absolutes, while D is unrelated.

GDP records production that can generally be identified and valued through market transactions or reliable imputed prices. Unpaid cooking, cleaning or caregiving within a household may create real services, but they usually have no observed market price and are difficult to measure consistently. Consequently they are normally excluded from official real GDP, which can understate non-market production. A is correct; the services are not necessarily illegal, imported or non-final.

The GDP deflator is a broad price index for domestically produced final goods and services; it measures the relationship between nominal and real GDP. Economic welfare is wider than prices or output. It also depends on income distribution, leisure, environmental quality, health, safety, and the quality of public services. The deflator does not measure only population or imports and does not mechanically double output. Thus, option A is correct.

The GDP deflator is constructed from prices and quantities of measured domestic output. A free digital service can provide substantial convenience, information, or consumer surplus even when its recorded market price is zero. Because no conventional transaction price captures that benefit, the deflator and GDP statistics may fail to reflect its full value. Thus option A is correct; the other choices do not follow from a zero price.
