Aggregates related to national income - NNP

The conversion from factor cost to market price is expressed as NNP_MP = NNP_FC + net indirect taxes. When NIT is zero, nothing is added to the factor-cost measure. Consequently, NNP_MP and NNP_FC have the same value. The result follows from the price-basis relationship, not from any assumption about the size of national income.

The relevant adjustment is net factor income from abroad (NFIA): NFIA = factor income received from abroad − factor income paid to foreigners. If receipts exceed payments, NFIA is positive. Adding positive NFIA converts a domestic aggregate into a national aggregate and raises national income measured through NNP.

The word ‘net’ means depreciation has been deducted, and the word ‘national’ means production by normal residents, including the relevant foreign factor-income adjustment. Since the valuation is at market prices, the correct aggregate is NNP at market price. GDP is gross and domestic, while NDP is net but domestic.

To convert GDP at factor cost into NNP at factor cost, first add net factor income from abroad to obtain GNP_FC, and then subtract depreciation to obtain NNP_FC. Thus, NNP_FC = GDP_FC + NFIA − depreciation = ₹1,850 crore + ₹70 crore − ₹220 crore = ₹1,700 crore. Therefore, option A is correct.

Unsold final goods have been produced during the current accounting year even though buyers have not purchased them yet. In national income accounting, the producer is treated as having purchased these goods for stock, so their value is recorded as inventory investment. This prevents current production from being omitted from NNP.

Illegal activities may generate real income and production, but participants often conceal them to avoid legal action or taxation. Consequently, surveys, tax records, and official accounts may fail to capture their value accurately. This under-reporting makes measured NNP lower than the actual income generated in the economy.

A homemaker's cooking, cleaning, childcare, and similar services provide genuine economic benefits, but they are usually produced and consumed within the household without a market transaction. Since national accounts mainly use observable market prices or reliable imputations, these unpaid services are generally excluded from measured NNP, limiting its welfare coverage.

The governing conversion is NNP_MP = NNP_FC + NIT, so NIT = NNP_MP − NNP_FC. Substitution gives NIT = ₹1,295 − ₹1,325 = −₹30 crore. Thus, option B is correct. The negative sign indicates that subsidies exceed indirect taxes by ₹30 crore. Option A reverses the subtraction, while C and D do not follow the relationship.

Depreciation measures the estimated loss of value or productive capacity of fixed capital used during production. Subtracting it from a gross measure gives a net measure, showing the output remaining after allowing for replacement of worn-out machines, buildings, and equipment. Thus NNP gives more meaningful information about net output than GNP.

NNP is based on the income earned by a country's normal residents, regardless of whether they produce inside or outside the domestic territory. A normal resident is an individual or institution whose centre of economic interest is connected with the country for a significant period. Short-term tourists and one-day visitors are generally excluded.

GNP is already a national measure, so no NFIA adjustment is required. To change GNP to NNP, deduct depreciation: GNP − depreciation = NNP. To change the factor-cost valuation to market-price valuation, add net indirect taxes. Therefore, NNP at MP = GNP at FC − depreciation + NIT, making option A correct.

Per capita NNP means NNP earned or produced on average per person. Therefore, total NNP is divided by the total population of the country: Per capita NNP = NNP ÷ Population. Depreciation, NIT and NFIA are adjustment items used in converting national income aggregates; they are not the denominator for a per-capita measure.

Per capita NNP is calculated by dividing total NNP by the total population. Therefore, per capita NNP₍FC₎ = ₹2,400 crore ÷ 30 crore = ₹80. The unit ‘crore’ appears in both the numerator and denominator and cancels out, leaving the result in rupees per person. Thus, each person’s share of NNP₍FC₎ is ₹80.

NNP measures the value of currently produced final goods and services after allowing for depreciation. Buying and selling an old share only transfers ownership of an already existing financial asset; it does not represent new production during the current period. Therefore, the transaction price of the old share is excluded from NNP, although a broker’s current service fee may be counted.

The first step is to identify exactly what the given aggregate represents: domestic or national, gross or net, and market price or factor cost. This prevents sign and conversion errors. After that, apply the appropriate adjustments: add or subtract NFIA for domestic-national conversion, subtract depreciation for gross-net conversion, and adjust NIT for market price-factor cost conversion.

NNP at factor cost is obtained by converting a domestic aggregate into a national aggregate. The required formula is NNP_FC = NDP_FC + NFIA. Therefore, NNP_FC = ₹1,100 crore + ₹70 crore = ₹1,170 crore. Positive NFIA means residents receive more factor income from abroad than foreigners earn domestically, so it is added.

National income is defined as NNP at factor cost. To convert NNP at market price into NNP at factor cost, subtract net indirect taxes, where NIT equals indirect taxes minus subsidies. Thus, NNP_FC = NNP_MP − NIT. NFIA and depreciation are not adjusted here because the aggregate is already national and net.

NNP at factor cost is the conventional measure of national income. It represents the net factor income generated by the normal residents of a country during an accounting period, after allowing for depreciation and using factor cost valuation. It is not merely domestic output, GDP at market price, or transfer payments, because those concepts differ in scope or valuation.

GNP at factor cost is already a national aggregate because it includes NFIA, and it is already valued at factor cost, so no NIT adjustment is required. The only difference between gross and net measures is consumption of fixed capital, or depreciation. Therefore, NNP_FC = GNP_FC − depreciation, making option A correct.

Consumption of fixed capital is another name for depreciation. The difference between a gross aggregate and its corresponding net aggregate equals depreciation. Therefore, consumption of fixed capital = GNP_FC − NNP_FC = ₹1,300 crore − ₹1,180 crore = ₹120 crore. Since both values are national and at factor cost, no other adjustment is required.

The relationship between comparable domestic and national aggregates is National Product = Domestic Product + NFIA. If domestic product is greater than national product, rearranging gives NFIA = National Product − Domestic Product, which must be negative. A negative NFIA means residents pay more factor income to the rest of the world than they receive from abroad.

At the same price basis and with both aggregates measured net, the difference between a national and a domestic aggregate is NFIA. The identity is NNP_MP = NDP_MP + NFIA. If NNP_MP equals NDP_MP, their difference is zero, so NFIA must be zero. This does not imply that NIT, depreciation, or subsidies are zero.

The difference between a net and a gross measure is depreciation, also called consumption of fixed capital. To move in the reverse direction from NNP to GNP, add depreciation: GNP_MP = NNP_MP + depreciation. NFIA changes domestic and national status, while NIT changes market price and factor cost; neither is relevant because both given aggregates are already national and at market price.

NNP is obtained after deducting depreciation from GNP. Therefore, to convert a net aggregate into its corresponding gross aggregate, depreciation must be added: GNP_MP = NNP_MP + depreciation = 1450 + 90 = ₹1540 crore. The calculation remains at market price because no tax or subsidy adjustment is required.

Factor cost means the payments made to the factors of production—such as wages to labour, rent to land, interest to capital and profit to entrepreneurship. NNP_FC therefore represents the net factor income generated by the normal production activity of a country after depreciation has been deducted. Taxes and subsidies are not the focus of this valuation.
