Methods of calculating national income - Value Added/Product Method

Aggregate expenditure is spending on the economy’s output by households, firms, government and the foreign sector. When it falls, firms may face lower sales and unintended inventories, leading them to cut production, investment and employment. Lower incomes can then reduce consumption further, creating a multiplier process that weakens demand and output. This feedback can deepen recessionary conditions.

Leakages are amounts that leave the spending stream, such as saving, taxes, and imports; they tend to reduce the immediate circular flow of income. Injections, such as investment, government expenditure, and exports, add spending to the flow. Their relative size affects aggregate income and equilibrium, so B is correct.

Finished goods produced during the year are part of current output even if buyers have not yet purchased them. When they remain unsold, they are recorded as an increase in inventories, also called change in stocks, under investment expenditure. This prevents current production from being omitted merely because the sale occurs later.

Value added is calculated as the value of gross output minus the value of intermediate consumption. This subtraction removes the value of goods and services purchased from other producers and prevents their value from being counted again. The remainder is the new value created by the producer through labour, capital, and organisation.

First calculate gross value added at market price: ₹5,00,000 − ₹2,10,000 = ₹2,90,000. To convert this into net value added at factor cost, deduct depreciation because the measure must be net, and deduct net indirect taxes because the measure must be at factor cost. Thus, NVA at factor cost = ₹2,90,000 − ₹40,000 − ₹30,000 = ₹2,20,000. Therefore, option A is correct.

To convert gross value added at market price into net value added at factor cost, first subtract depreciation to remove the value of capital consumed during production. Then subtract net indirect taxes to remove the difference between market price and factor cost. The calculation is: NVA at factor cost = ₹80 crore − ₹10 crore − ₹6 crore = ₹64 crore. Hence, option D is the only correct answer.

Under the production method, the net value added at factor cost of all producing sectors is aggregated to obtain domestic income. Net value added excludes depreciation and is valued at factor cost, so it represents factor earnings generated by domestic production. Net factor income from abroad is then added separately to convert domestic income into national income.

When an owner works in his or her own factory without receiving a separately recorded wage, the labour service still contributes to production. Its estimated value is treated as an imputed factor contribution and may form part of mixed income, which combines returns to the owner's labour and capital. It is therefore included in production-related income rather than treated as a transfer payment or foreign income.

NVA at factor cost is obtained after deducting intermediate consumption, depreciation, and net indirect taxes from the relevant output measure, depending on the accounting sequence used. A negative NVA at factor cost means that deductions such as consumption of fixed capital and net indirect taxes are larger than the unit's gross value contribution. It does not mean that output is necessarily zero.

Raw materials, electricity used in production, and packing materials are normally intermediate inputs purchased for producing the output, so their cost is deducted from gross output. Factory rent, however, is a payment for the use of a factor of production, namely land or buildings. It is factor income and forms part of value added; deducting it as intermediate consumption would understate value added.

The dealer’s commission represents a distribution or brokerage service supplied during the current year, so it is current production and forms part of the dealer’s value added. The used car itself was produced earlier, so its complete resale value is not counted again. A pension is a transfer payment, and buying existing shares is a financial transaction, not current production. Thus B is correct.

To convert GVAₘₚ into NVA𝒇𝒄, first remove depreciation to change gross value into net value. Then remove net indirect taxes, where net indirect taxes equal indirect taxes minus subsidies, to change market prices into factor cost. Therefore NVA𝒇𝒄 = GVAₘₚ − Depreciation − Net Indirect Taxes. Option A gives the complete correct sequence.

First calculate the value of output by adjusting sales for the change in stock: Value of Output = Sales + Closing Stock − Opening Stock = ₹6,50,000 + ₹95,000 − ₹70,000 = ₹6,75,000. Then subtract intermediate consumption: GVAₘₚ = ₹6,75,000 − ₹2,80,000 = ₹3,95,000. Hence option A is correct.

Agricultural households may consume part of their own harvest, exchange output informally, or produce goods without recording a market sale. These activities are real output, but their market value is not directly observed. National-income compilers therefore need reliable quantities, suitable prices, and careful imputation to estimate value added. The other alternatives describe conditions that are not the normal measurement problem.

First calculate GVA at market price: Output − Intermediate Consumption = ₹9,00,000 − ₹4,20,000 = ₹4,80,000. Then NVA at factor cost = GVA at market price − Depreciation − Net Indirect Tax = ₹4,80,000 − ₹70,000 − (−₹20,000) = ₹4,30,000. The negative tax increases the result by ₹20,000.

A licence payment must be examined according to its economic nature. If it is a compulsory payment without a corresponding service, it may be treated as a tax related to production; if it is payment for a specific government service, it may be recorded as a service charge or intermediate expense. Correct classification is necessary for accurate value added and market-price calculations. Hence, option A is correct.

Under the value-added method, the value of the final product equals the sum of value added at every stage of production. Therefore, the value added in the final stage is calculated as ₹2,40,000 − ₹70,000 − ₹90,000 = ₹80,000. This avoids counting the same intermediate goods more than once.

GVA is calculated as value of output minus intermediate consumption. Wages are factor payments to workers and are not intermediate inputs purchased from other producers. If wages are wrongly included in intermediate consumption, they will be deducted from output, causing GVA to be understated by the amount of wages.

The relationship is GVA at market prices = value of output − total intermediate consumption. Thus, total intermediate consumption is ₹4,80,000 − ₹1,75,000 = ₹3,05,000. Since intermediate services account for ₹55,000, goods input equals ₹3,05,000 − ₹55,000 = ₹2,50,000. Therefore, option A is correct.

GVA at market prices is a gross domestic measure because it includes consumption of fixed capital, or depreciation. National income is a net measure and also requires the appropriate domestic-to-national and market-price-to-factor-cost adjustments. Calling GVA at market prices national income without depreciation therefore confuses a gross aggregate with a net one.

The relationship is GVA at factor cost = GVA at market prices − net indirect taxes, where net indirect taxes equal indirect taxes minus subsidies. If subsidies exceed indirect taxes, net indirect taxes are negative. Subtracting a negative amount increases the result, so GVA at factor cost is greater than GVA at market prices.

Total receipts are not automatically equal to the value of current output. Receipts may include the sale of goods produced earlier, sale of an old asset, loans, or other financial and non-production items. To calculate value of output, only current production is counted, with appropriate additions such as closing stock and deductions such as opening stock where applicable. Therefore, receipts must be carefully adjusted before value added is calculated.

First calculate value of output: sales + change in stock + own-use output = ₹14,50,000 + (₹2,10,000 − ₹1,75,000) + ₹60,000 = ₹15,45,000. GVA at market price equals value of output minus intermediate consumption. Therefore, GVA at market price = ₹15,45,000 − ₹8,25,000 = ₹7,20,000, so option B is correct.

First compute net indirect tax: production tax + product tax − production subsidy = ₹90,000 + ₹70,000 − ₹50,000 = ₹1,10,000. Convert GVA at market price to NVA at factor cost by subtracting both net indirect tax and depreciation: ₹9,60,000 − ₹1,10,000 − ₹1,10,000 = ₹7,40,000. Hence, option A is correct.

The trader's gross trading margin is sales minus the purchase value of goods: ₹6,10,000 − ₹5,20,000 = ₹90,000. Storage and advertising are intermediate services used in carrying out the trading activity, so they are deducted from the margin. Therefore, GVA at market price = ₹90,000 − ₹18,000 − ₹12,000 = ₹60,000. Option B is correct.
