GDP and Welfare

GDP is a measure of marketed production, not a complete measure of environmental well-being. If air quality deteriorates without a corresponding market transaction, the loss may not be deducted from measured GDP. People can therefore suffer poorer health and quality of life while recorded output stays unchanged. Hence option A is correct; productivity and public-health improvements generally support welfare, while price stability is not itself this environmental loss.

Public parks provide a non-market or publicly provided amenity. Greater access can improve recreation, health, and quality of life, so welfare may rise. However, if no additional market payment or recorded production occurs, the full benefit is not added to GDP; measured GDP may change little. Thus option B is correct. Equal movement is not necessary, and the other choices contradict the likely welfare effect.

GDP is useful because it summarizes the market value of final goods and services produced, providing information about income and material consumption possibilities. It is incomplete because welfare also depends on distribution, unpaid work, environmental quality, leisure, health, education, security, and the quality of goods. Therefore option B gives the balanced conclusion. A is too absolute, while C and D wrongly deny other relevant information.

GDP generally values production through market transactions or imputations with observable prices. When a household hires a domestic worker, a paid service creates recorded income and expenditure; when a family member performs the same task unpaid, it is usually outside measured GDP. This unequal treatment shows the limitation of market-based valuation and the omission of non-market household work. Therefore option B is correct, not depreciation, borders, or double counting.

Per-capita real GDP is calculated by dividing real GDP by population. Since ₹1 crore equals ₹100 lakh, ₹900 crore equals ₹90,000 lakh. Therefore, ₹90,000 lakh ÷ 15 lakh people = ₹6,000 per person. Option A is correct. The other choices result from mishandling the crore-to-lakh conversion or dividing 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.

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.
