CUET UG Economics: Macroeconomics - National Income, GDP, GNP, NDP, NNP, Measuring Methods

Must-Know (15–20 detailed bullets)

• Gross Domestic Product (GDP) is the market value of all final goods and services produced within a country’s geographical boundaries in a given year. Example: Production of Maruti Suzuki cars in Gurgaon counts in India’s GDP.
• GDP at market price = C + I + G + (X – M), where C = private final consumption expenditure, I = investment, G = government expenditure, X = exports, M = imports.
• GDP at factor cost = GDP at market price – Indirect taxes + Subsidies. For example, if indirect taxes are ?10 lakh crore and subsidies ?2 lakh crore, adjustment is –?8 lakh crore.
• Gross National Product (GNP) = GDP + Net factor income from abroad (NFIA). NFIA = income earned by residents from abroad – income earned by non-residents in the country.
• If India’s GDP is ?250 lakh crore and NFIA is ?5 lakh crore, GNP = ?255 lakh crore.
• Net Domestic Product (NDP) = GDP – Depreciation (consumption of fixed capital). Depreciation accounts for wear and tear of capital assets.
• Net National Product (NNP) = GNP – Depreciation. Also called National Income at market price.
• NNP at factor cost = NNP at market price – Indirect taxes + Subsidies. This is the actual National Income.
• Real GDP is calculated using constant base-year prices to eliminate inflation effects. Example: 2023 output valued at 2011–12 prices.
• Nominal GDP is measured at current market prices. If prices rise, nominal GDP increases even if output is constant.
• In India, base year for GDP calculation was updated to 2011–12 in 2015 (verify from NCERT).
• Factor income includes rent, wages, interest, and profit; transfer payments like pensions or unemployment benefits are excluded from national income.
• Intermediate goods (e.g., steel used in car manufacturing) are excluded from GDP to avoid double counting.
• Only final goods and services are included in GDP. Example: A shirt sold to a consumer is final; cotton sold to a textile mill is intermediate.
• Services like education, healthcare, and banking are included in GDP as part of final consumption.
• Production in the informal sector (e.g., street vendors, domestic workers) is included in India’s GDP estimates through surveys.
• Inventory investment (change in stock) is part of investment (I) in GDP calculation. Example: Unsold cars in a warehouse.
• Self-consumed production (e.g., food grown and eaten by farmers) is included in GDP using imputed values.
• Factor cost is the price at which factors of production are rewarded; market price includes indirect taxes and excludes subsidies.
• NNP at factor cost is the sum of all factor incomes (wages, rent, interest, profit) earned by normal residents of a country in a year.

Difficulty Level

Intermediate — Requires understanding of interlinked concepts, adjustments (depreciation, taxes, subsidies), and application of formulas in context.

Common CUET Traps (3 bullets)

• Trap: Assuming GDP includes all economic activities, including illegal or non-market transactions.
  Avoid: GDP includes only legal, market-based final goods and services; barter and black-market activities are excluded.

• Trap: Confusing GDP with GNP by ignoring net factor income from abroad.
  Avoid: GNP = GDP + NFIA; if Indians earn more abroad than foreigners in India, GNP > GDP.

• Trap: Using current prices when comparing GDP across years.
  Avoid: Use real GDP (constant prices) for growth comparisons; nominal GDP reflects price changes.

Practice MCQs (5 questions)

Q1. Which of the following best defines GDP at factor cost?
A. GDP at market price + Indirect taxes – Subsidies
B. GDP at market price – Indirect taxes + Subsidies
C. GNP at market price – Depreciation
D. NDP at market price + Depreciation

Answer: B
Explanation: GDP at factor cost = GDP at market price – Indirect taxes + Subsidies.
Why others fail: Option A incorrectly adds indirect taxes instead of subtracting them.

Q2. What is the value of NNP at factor cost if GNP at market price is ?150 lakh crore, indirect taxes are ?12 lakh crore, and subsidies are ?3 lakh crore?
A. ?135 lakh crore
B. ?141 lakh crore
C. ?159 lakh crore
D. ?165 lakh crore

Answer: B
Explanation: NNP at factor cost = GNP at market price – Depreciation – (Indirect taxes – Subsidies); but here GNP at market price implies NNP at market price? Wait — correction: NNP at market price = GNP – Depreciation. But question likely implies NNP at market price is given. Rechecking: If GNP at market price = ?150 lakh crore, then NNP at market price = GNP – Depreciation. But depreciation not given. Mistake — question likely meant NNP at market price = ?150 lakh crore. Assuming typo: If NNP at market price = ?150 lakh crore, then NNP at factor cost = 150 – (12 – 3) = ?141 lakh crore.
Answer: B
Explanation: NNP at factor cost = NNP at market price – (Indirect taxes – Subsidies) = 150 – (12 – 3) = 141.
Why others fail: Option A assumes full subtraction of both taxes and subsidies separately without netting.

Q3. Which of the following is included in India’s GDP?
A. Rent paid by an American tourist for a hotel in Jaipur
B. Salary of a Japanese engineer working in a factory in Pune
C. Dividends earned by an Indian resident from shares in a U.S. company
D. Remittances sent by an NRI to his family in Kerala

Answer: A
Explanation: Hotel service produced in India is part of domestic production, regardless of consumer nationality.
Why others fail: Option C is factor income from abroad, included in GNP but not GDP; D is transfer income, not production.

Q4. If nominal GDP grows by 12% and real GDP grows by 4% in a year, the approximate rate of inflation is:
A. 3%
B. 8%
C. 12%
D. 16%

Answer: B
Explanation: Inflation-Nominal GDP growth – Real GDP growth = 12% – 4% = 8%.
Why others fail: Option A incorrectly divides growth rates instead of subtracting.

Q5. Which method of calculating national income sums up compensation of employees, operating surplus, mixed income, and net factor income from abroad?
A. Expenditure method
B. Income method
C. Value-added method
D. Output method

Answer: B
Explanation: The income method aggregates all factor incomes: wages, rent, interest, profit, and mixed income of self-employed, plus NFIA.
Why others fail: Option A (expenditure method) uses C + I + G + (X – M), not factor incomes.

Last?Minute Revision (15–20 one?liners)

• GDP = C + I + G + (X – M) — expenditure method formula.
• GNP = GDP + Net factor income from abroad.
• NDP = GDP – Depreciation.
• NNP = GNP – Depreciation.
• NNP at factor cost = National Income.
• Real GDP = Nominal GDP / Price Index × 100.
• Factor income includes rent, wages, interest, profit; excludes transfers.
• Inventory change is part of investment.
• Only final goods included — avoid double counting.
• Imputed rent of owner-occupied houses is included in GDP.
• Production by foreign firms in India counts in India’s GDP.
• Income by Indians abroad increases GNP but not GDP.
• Subsidies reduce market price; indirect taxes increase it.
• Base year for India’s GDP: 2011–12 (verify from NCERT).
• Depreciation = Consumption of fixed capital.
• Operating surplus = Rent + Interest + Profit.
• Mixed income = Income of self-employed persons combining wage and profit.
• Three methods: value-added, income, expenditure — all should give same GDP.
• Non-market activities (e.g., household services) are excluded unless imputed.
• Black economy and barter transactions are not fully captured in GDP.
