Methods of calculating national income - Expenditure Method

Production kept for the producer’s own use can still be part of current final output, even when it is not sold in a market. If its imputed value is omitted from the expenditure estimate, measured final expenditure becomes smaller than the actual value of production. Consequently, national income or GDP may be underestimated. The omission cannot cause imports to double.

A reliable sequence is to calculate GDP at market price from consumption, government expenditure, investment, and net exports. Next subtract depreciation to remove capital consumption and subtract net indirect taxes to convert market prices into factor cost, obtaining NDPFC. Finally add NFIA to convert domestic income into national income, NNPFC. This sequence prevents sign and classification errors.

Output retained for self-consumption is still produced during the current accounting period and is available for final use. Since no market sale records its value, national accounts assign an imputed value, normally based on the market price of a comparable product. That value is included in final expenditure and GDP at market prices; it is not depreciation, an import, or a transfer payment.

A machine purchased by a firm is a capital good and therefore forms part of gross capital formation, such as GFCF, in expenditure accounting. However, because the machine was produced abroad, its value is not part of domestic production. It is therefore recorded as an import and subtracted in the net-export term. The two entries prevent foreign production from inflating domestic GDP.

The old asset itself was produced in an earlier period, so its resale price is not current production and is excluded from current GDP. The broker, however, provides a real intermediation service during the current year. The commission is the payment for that newly produced service and can therefore be included separately in expenditure and GDP, provided it is not counted twice elsewhere.

Under the expenditure method, GDPMP = PFCE + GFCE + GFCF + change in stocks + exports − imports. Substituting the values gives 1200 + 350 + 500 − 40 + 260 − 310 = 1960. The negative change in stocks is subtracted, while imports are also subtracted from expenditure because they are not domestic production. Therefore option B is correct.

A foreign tourist’s payment for a hotel service supplied within the domestic territory is expenditure by a non-resident on domestically produced output. In national accounting, such sales of domestic goods or services to foreign residents are recorded as exports, including service exports. It is not an import, because the service is produced domestically, and it is not capital formation because no productive asset is acquired.

GDPMP is converted to NNPFC in three steps. First subtract depreciation to change gross product into net product. Next subtract net indirect taxes (NIT) to change market prices into factor cost. Finally add net factor income from abroad (NFIA) to change domestic product into national product. Thus NNPFC = GDPMP − depreciation − NIT + NFIA, making option B correct.

Double counting occurs when the value of an intermediate good is added separately even though it is already included in the price of the final good. Wood is an intermediate input in furniture production. Its value is embodied in the furniture’s final selling price, so adding both the wood expenditure and the final furniture value counts the same production twice. The other options describe final purchases or services.

A foreign online course is a service produced outside the domestic territory. Since a resident household purchases it for consumption, the expenditure may first appear in Private Final Consumption Expenditure, or PFCE. However, imports are subtracted in the expenditure identity, so the value of the foreign service is deducted as an import. This prevents foreign production from being counted in domestic GDP.

An owner-occupied house provides housing services to its owner even though no rent is paid to a landlord. To measure the value of all housing services produced and consumed, national-income accounting assigns an imputed rent equal to the estimated rent that the house could earn in the market. This imputed housing service is treated as private final consumption expenditure, not as a transfer or a new investment.

Software can be an intangible fixed asset when a firm uses it repeatedly in production for a period extending beyond one year. Such software provides continuing productive benefits and is therefore treated as gross fixed capital formation, subject to the relevant accounting rules. Software bought merely for resale is inventory, a gift to employees is not fixed capital formation, and a tourist’s purchase is unrelated to the firm’s capital investment.

Government expenditure is classified according to the economic nature and use of the item purchased, not according to the payment instrument or the number of personnel. Defence equipment used up in providing current government services may be treated as government final consumption expenditure. Equipment that creates or adds to a durable productive or capital asset is treated as capital formation, subject to the accounting classification. Thus, the decisive issue is whether the purchase is for current final use or creates a capital asset.

GDP at market price measures the market value of final goods and services produced within the domestic territory during a period. The expenditure method therefore adds consumption, investment, government expenditure and net exports to measure domestic production. Net Factor Income from Abroad (NFIA) records factor income flows between residents and the rest of the world. It is added only when converting a domestic product measure into a national product or national income measure, not while calculating GDP itself.

Routine maintenance of a public park uses resources to provide or preserve a current government service, so it may be recorded as government final consumption expenditure. Constructing a new park creates a durable physical asset that provides services over future periods, so it may be classified as gross capital formation. The exact accounting treatment can depend on the scale and nature of the work.

A share purchase exchanges money for a financial claim on an existing company; it does not purchase a newly produced good or service. If it were incorrectly added to final expenditure, the expenditure total would include a non-production financial transaction. This would overstate measured current output and national income, although the financial wealth or ownership claim itself may change.

A government pension is generally a transfer payment because the recipient does not provide a current good or service in exchange for that payment. By contrast, the salary paid to a government employee is compensation for current labour used to produce government services. It can therefore enter government final consumption expenditure through the cost of those services, subject to national-accounting conventions.

Gross fixed capital formation refers to additions to fixed assets such as machinery, buildings, and infrastructure, including relevant improvements. Gross capital formation is broader: it includes gross fixed capital formation plus changes in inventories, or stock formation. The distinction prevents errors in expenditure calculations, especially when inventory investment is given separately in numerical questions.

The treatment depends on the institutional arrangement. If a company purchases meals or catering for employees, the payment is connected with a service supplied to the firm and may be recorded as an intermediate input or as employee compensation in kind. It is not automatically NX, GFCE, or NFIA. Therefore, option A is the only suitably qualified and conceptually correct answer.

GDP measures production within a country’s domestic territory, whereas national product or national income relates to the factor income of the country’s normal residents, wherever that income is earned. NFIA equals factor income received from abroad minus factor income paid abroad. Adding NFIA changes the domestic concept into the national concept; it does not change prices or grossness.

Services supplied by private non-profit institutions serving households are treated as part of household-oriented final consumption in the expenditure classification used here. Their final service cost is therefore included in PFCE, not GFCE. NX records exports minus imports, while NIT is a price-and-tax adjustment rather than a category of final consumption expenditure. Thus A is correct.

Wheat produced by a farmer and retained for the household is still current production of a good, even though no market sale occurs. National accounting therefore assigns it an imputed value, generally based on the comparable market price, and records it as household final consumption. It is not an import, financial asset or unrecorded activity simply because the transaction is non-market.

The resale price of an old good is excluded because the good was produced in an earlier period and its resale does not represent current production. However, brokerage, commission, transport, or other services provided during the resale are current services. Their service charges may therefore be included in national income expenditure if they are paid for during the current period.

Free government services do not have an observable market price because beneficiaries are not charged. In national accounting, their value is therefore estimated by the cost of producing them. For a vaccination programme, this may include employee compensation, medicines, equipment, administration, and other production expenses. This estimated value enters government final consumption expenditure.

The expenditure formula for GDP is GDP = C + I + G + X − M. Consumer expenditure can include imported goods, but those goods were produced abroad. Subtracting imports removes their foreign-production component from domestic expenditure. If imports are not subtracted, foreign output remains inside the calculation, so GDP is overstated and no longer measures only production within the domestic territory.
