National Income — Set 5

Correct Answer: B. Nominal National Income increases relative to Real Income

• **Rising GDP Deflator** = indicates that the general price level has risen, causing Nominal GDP to grow faster than Real GDP. • **Nominal exceeds Real** — when prices rise, the same physical output appears larger in nominal terms; the deflator captures this gap. • 💡 Wrong-option analysis: [Option A] Real National Income increases: a rising deflator means prices rose, not output; [Option C] National Income automatically decreases: nominal income rises, it does not decrease; [Option D] It has no impact: a rising deflator directly affects the nominal-real income gap.

Correct Answer: B. Value of Output - Intermediate Consumption

• **Value Added = Value of Output - Intermediate Consumption** — it isolates a firm's specific contribution from the total output value. • **Avoids double counting** — by subtracting the cost of inputs already counted elsewhere, each firm's unique addition to the economy is captured. • 💡 Wrong-option analysis: [Option A] Gross Profit - Tax: profit is the residual after all costs, not the same as value added; [Option C] Total Revenue - Labour Cost: this ignores other intermediate costs like raw materials; [Option D] Final Sales - Initial Investment: investment is not the same as intermediate consumption.

Correct Answer: D. Wages and salaries in cash and kind

• **Compensation of Employees** = all wages and salaries paid in cash and kind for work done, including basic pay, dearness allowance, and social security contributions. • **Largest component of Income Method** — in most economies, employee compensation forms the biggest share of national income. • 💡 Wrong-option analysis: [Option A] Old-age pension: a transfer payment, not earned compensation for current work; [Option B] Travel allowance for a personal trip: personal expense reimbursement not for productive work; [Option C] Gifts from employers: not paid in exchange for productive services.

Correct Answer: B. Domestic Income

• **Domestic Income = NDP at Factor Cost** — it represents total factor income generated within the country's geographical boundaries. • **Excludes NFIA** — unlike National Income (NNP at FC), Domestic Income does not include net earnings from abroad. • 💡 Wrong-option analysis: [Option A] National Income: refers to NNP at factor cost, which includes NFIA; [Option C] Disposable Income: what households can spend after direct taxes; [Option D] Private Income: includes all private sector earnings and transfer payments.

Correct Answer: B. The distortion in growth rates due to the choice of the base year

• **Base Year Effect** = the distortion in growth rates that arises when the reference year is changed, because economic structures differ across time. • **Periodic revisions needed** — updating the base year ensures it reflects the current structure of the economy, reducing statistical distortion. • 💡 Wrong-option analysis: [Option A] Impact of population on GDP: this relates to per capita income, not the base year effect; [Option C] Fixed cost of starting a new year: a fabricated concept unrelated to economics; [Option D] Seasonal variation in GDP: seasonality is adjusted separately, not through base year selection.

Correct Answer: D. Private Income

• **Private Income** = includes factor income from all sources and transfer payments but excludes government sector income; corporate taxes and undistributed profits are its components. • **Private Income exceeds Personal Income** — corporate tax and retained earnings are deducted from private income to arrive at personal income. • 💡 Wrong-option analysis: [Option A] Disposable Income: personal income after direct taxes, smaller than private income; [Option B] Transfer Payments: added to factor income to get personal income, not a category containing corporate tax; [Option C] Personal Income: corporate taxes and undistributed profits are deducted from private income to get personal income.

Correct Answer: D. Wealth

• **Wealth is a Stock variable** = it represents an accumulated amount measured at a specific point in time, unlike income which is measured over a period. • **Stock at a moment** — examples: foreign exchange reserves, money supply, capital stock — all measured on a specific date. • 💡 Wrong-option analysis: [Option A] Interest on Capital: a flow variable measured over a period; [Option B] Production of Sugar: a flow measured over a year; [Option C] Capital Formation: a flow variable representing investment over a period.

Correct Answer: D. Rent + Interest + Profit

• **Operating Surplus = Rent + Interest + Profit** — the factor income that accrues to owners of property and entrepreneurship. • **Excludes employee compensation** — it is the residual national income after subtracting wages and mixed income. • 💡 Wrong-option analysis: [Option A] Sales - Expenses: accounting profit of a firm, not the macroeconomic operating surplus; [Option B] Exports - Imports: this is the trade balance or net exports; [Option C] Wages + Rent + Interest: incorrectly includes wages which belong to employee compensation.

Correct Answer: B. Government Final Consumption Expenditure

• **Government Final Consumption Expenditure (GFCE)** = government spending on collective goods and services like defence, health, and administration. • **Excludes transfers and capital formation** — pensions and infrastructure spending are not part of GFCE. • 💡 Wrong-option analysis: [Option A] National Debt: accumulated government borrowings over time, not a spending category; [Option C] Public Savings: what remains of government revenue after expenditure; [Option D] Government Investment: classified as capital expenditure, not consumption expenditure.

Correct Answer: D. Adding the value of a good at multiple stages of production

• **Double Counting** = the error of adding the value of a good at multiple production stages, inflating the total national income figure. • **Example** — counting both wheat's value (Rs.10) and bread's value (Rs.25) separately counts Rs.10 twice; only the Rs.25 final value should count. • 💡 Wrong-option analysis: [Option A] Including both direct and indirect taxes: taxes are adjustments, not double-counting errors; [Option B] Adding exports and imports together: Net Exports = X - M in the Expenditure Method; [Option C] Calculating GDP twice a year: frequency of calculation is unrelated to double counting.
