National Income Aggregates and GDP for CUET Economics

Q: What is NFIA?

Domestic product counts what is produced within the domestic territory. National product counts what the country's normal residents earn, wherever they produce.

Q: Which incomes reach households?

Personal income = national income − undistributed profits − corporate tax − net interest paid by households + transfers to households from the government and firms. Personal disposable income = personal income − personal taxes − non-tax payments (fees, fines). It is spent or saved. Net national disposable income = NNP at MP + net current transfers from the rest of the world.

Q: How are price changes taken out?

Nominal GDP values this year's output at this year's prices. Real GDP values it at base-year prices, so it moves only when quantities move.

Q: Why is more GDP not always better?

Distribution: GDP can rise while most people's income falls. Non-monetary exchanges: barter and unpaid work are not counted. Externalities: harm such as pollution is not subtracted, and benefits such as a neighbour's garden are not added.

The core idea

Every aggregate's name is three choices: gross or net, domestic or national, market price or factor cost. Each pair differs by one item, so any aggregate can be reached from any other by adding or subtracting the right items.

From → to	Adjustment
Gross → net	− depreciation
Domestic → national	+ NFIA
Market price → factor cost	− net indirect taxes (indirect taxes − subsidies)
Nominal → real	÷ price index × 100

Domestic and national

What is NFIA?

Domestic product counts what is produced within the domestic territory. National product counts what the country's normal residents earn, wherever they produce.

Net factor income from abroad

\text{NFIA} = \text{factor income earned by residents abroad} - \text{factor income earned by non-residents here}

\text{GNP} = \text{GDP} + \text{NFIA}

The domestic territory includes the country's embassies abroad, and excludes foreign embassies and international bodies within it. A resident is someone whose centre of economic interest is in the country, whatever the citizenship.

Watch out

NFIA is about factor incomes (wages, rent, interest, profit). Net exports are about trade in goods and services, and gifts or remittances are transfers: neither is part of NFIA.

Market price, basic prices and factor cost

Where do taxes come in?

Market prices include indirect taxes and are lowered by subsidies. Factor cost is what the factors of production receive.

Basic prices sit between them. Production taxes (land revenue, stamp duty, paid whatever the output) are added to factor cost to reach basic prices; product taxes (GST, customs duty, paid per unit) are added to reach market prices.

The ladder

\text{GVA}_{basic} = \text{GVA}_{FC} + \text{production taxes} - \text{production subsidies}

\text{GVA}_{MP} = \text{GVA}_{basic} + \text{product taxes} - \text{product subsidies}

Example 1 · From GDP to national income

GDP at MP = ₹1,000 crore, depreciation = 100, net indirect taxes = 80, NFIA = −20. Find national income (NNP at FC).

NDP at MP = 1,000 − 100 = 900.
NDP at FC = 900 − 80 = 820 (domestic income).
NNP at FC = 820 + (−20) = 800.

Answer

₹800 crore

Working backwards reverses every sign: from national income ₹800 crore, add net indirect taxes and depreciation and subtract NFIA (−20 subtracted is +20) to get back to GDP at MP of ₹1,000 crore.

Personal and disposable income

Which incomes reach households?

Personal income = national income − undistributed profits − corporate tax − net interest paid by households + transfers to households from the government and firms.
Personal disposable income = personal income − personal taxes − non-tax payments (fees, fines). It is spent or saved.
Net national disposable income = NNP at MP + net current transfers from the rest of the world.

Personal income can exceed national income when transfers are large.

Real and nominal GDP

How are price changes taken out?

Nominal GDP values this year's output at this year's prices. Real GDP values it at base-year prices, so it moves only when quantities move.

GDP deflator

\text{GDP deflator} = \frac{\text{Nominal GDP}}{\text{Real GDP}} \times 100

Example 2 · Two goods

Base year: apples ₹10 × 100, bread ₹20 × 50. Year 2: apples ₹12 × 120, bread ₹25 × 60.

Nominal GDP year 2 = 12 × 120 + 25 × 60 = 1,440 + 1,500 = 2,940.
Real GDP year 2 = 10 × 120 + 20 × 60 = 2,400; base-year GDP = 2,000.
Deflator = 2,940 ÷ 2,400 × 100 = 122.5; real growth = 400 ÷ 2,000 = 20%.

Answer

Real GDP grew 20%; prices rose 22.5%

The deflator covers all goods produced in the country, including capital goods; the consumer price index covers a basket bought by consumers, including imports.

GDP and welfare

Why is more GDP not always better?

Distribution: GDP can rise while most people's income falls.
Non-monetary exchanges: barter and unpaid work are not counted.
Externalities: harm such as pollution is not subtracted, and benefits such as a neighbour's garden are not added.

Per capita real GDP is a better guide to average living standards than total GDP, but it still misses these three.

Exam shortcuts

GNP > GDP only when NFIA > 0.
National income = NNP at FC = NDP at FC + NFIA.
Subsidies > indirect taxes: factor cost > market price.
In the base year, real = nominal and the deflator = 100.

Common mistakes

Adding NFIA with the wrong sign when it is negative.
Calling NDP at FC "national income" (it is domestic income).
Dividing nominal GDP by last year's GDP to get the deflator.
Treating remittances as factor income from abroad.

Adjustments

Net = gross − depreciation
National = domestic + NFIA
FC = MP − (indirect taxes − subsidies)

Income measures

National income = NNP at FC
PDI = personal income − personal taxes − fees and fines
NNDI = NNP at MP + net current transfers from abroad

Real GDP and welfare

Deflator = nominal ÷ real × 100
Real GDP uses base-year prices
GDP misses distribution, non-market activity and externalities

What money is, and how much of it there is, comes next in money and its functions.
