Methods of calculating national income - Value Added/Product Method

Agricultural output produced for self-consumption is still production of goods within the domestic production boundary. Because it is not sold in a market, its value is imputed using the appropriate prevailing or estimated market price. Including it ensures that national income measures actual production rather than only market sales. It is neither a transfer payment nor an import. Therefore A is correct.

Gross value added is calculated by subtracting the value of intermediate consumption from the value of output. Here, GVA = ₹12,00,000 − ₹7,25,000 = ₹4,75,000. Yarn, electricity, and dyes are inputs used in production, so their value must be deducted to avoid counting their contribution again. Therefore, option C is the correct answer.

The purchase or sale of an old share is a financial transaction that merely transfers ownership of an existing financial asset. No new good or service is produced by the share itself in the current accounting year. Including its price would therefore count a transfer of ownership rather than current production and would overstate value added. Only a current service connected with the transaction, such as brokerage, may be included because that service is newly produced.

The old share is an existing financial asset, so its sale price is not current production and is excluded from the value-added calculation. However, the broker performs a real intermediation service during the current year and receives a commission for arranging or executing the transaction. That commission is payment for newly provided output and is therefore included as the value of a current service.

An old house was produced in an earlier year, so its resale price does not represent current domestic production. The purchase of shares is a financial transaction, and selling an old machine only transfers an existing asset. In contrast, the broker provides a new service in the current year while arranging the house sale. The broker's fee is therefore included in current output and value added.

The value of output is calculated as sales plus the value of current production that remains unsold minus the value of opening stock sold during the year: Value of output = Sales + Closing-stock addition − Opening-stock withdrawal. Thus, ₹10,00,000 + ₹1,50,000 − ₹60,000 = ₹10,90,000. The subtraction prevents last year's production from being counted as this year's output.

A new computer machine is a capital good because it supports production over several accounting periods rather than being completely used up in the year of purchase. Intermediate consumption includes inputs such as electricity, fuel, or raw materials that are consumed during current production. The computer is recorded as fixed capital formation, while its depreciation is recognized gradually over its useful life.

Value added is calculated as the value of output minus intermediate consumption. Wages paid to production workers are compensation for labour services and are a primary factor payment, so they form part of value added rather than intermediate consumption. Electricity, wood, and packing boxes are goods or services used up during production; their costs are deducted to avoid counting the same inputs more than once.

Double counting occurs when the total selling value is included at every stage of production. The value of an intermediate good already includes the value of inputs purchased from earlier stages, so adding every stage’s sales counts the same output repeatedly. Adding only final goods or summing value added avoids this error.

A trader generally purchases a finished good and resells it; therefore, the entire sale value represents the value of the good produced by another unit, not new output created by the trader. The trader’s own output is the trading margin, which measures the service of making the good available to buyers.

GVA at market price is calculated by subtracting intermediate consumption from the value of output. For the wholesaler, the trading output is the margin earned: ₹4,60,000 − ₹4,00,000 = ₹60,000. Transport is an intermediate expense of ₹15,000, so GVAₘₚ = ₹60,000 − ₹15,000 = ₹45,000. Therefore, option B is correct.

Production taxes and product taxes are indirect taxes. Along with subsidies, they create the difference between market prices and factor cost. Therefore, net indirect tax adjustment is used: market-price value added is converted to factor-cost value added by subtracting net indirect taxes, while subsidies reduce the net tax.

Value of output measures production during the accounting year, not merely goods sold during that year. Finished goods produced in the current year but still held as closing stock are part of current production. Adding closing stock ensures that unsold current output is included and is not mistakenly omitted.

Opening stock consists of goods carried forward from the previous accounting year. If these goods are sold in the current year, their value appears in current-year sales even though they were not produced this year. Deducting opening stock removes this previous-year production and helps measure only current-year output.

The total NVA at factor cost generated by all producing units within the domestic territory is called domestic income. It measures the factor payments—such as wages, rent, interest and profit—arising from domestic production after deducting depreciation and net indirect taxes as required. Personal, private and transfer income are different aggregates. National income would be obtained after adjusting domestic income by Net Factor Income from Abroad (NFIA). Hence, option A is correct.

A free government hospital provides a non-market service, so there is no meaningful price determined through market sales. National accounting therefore values such government services by their cost of production, including compensation of employees and relevant intermediate inputs. Profit or patients’ income is not used to measure the service’s output.

Chemicals used up during production are intermediate inputs because they are consumed or transformed within the current production process. They do not provide repeated services over several accounting periods. A factory building, machine and durable office furniture are fixed capital because they are used repeatedly for production over a longer period.

Intermediate consumption consists of goods and services that are used up during the current production process, such as raw materials, fuel, and purchased services. Interest on a bank loan is a payment for the use of financial capital, so it is treated as a return to a factor of production, not as a physical production input deducted from output. Therefore, option A is correct.

To convert NVA at factor cost into GVA at market prices, add depreciation to change net into gross and add net indirect taxes to change factor cost into market prices. Thus, GVA at MP = NVA at FC + depreciation + net indirect taxes = ₹8,00,000 + ₹90,000 + ₹50,000 = ₹9,40,000. Hence, option C is correct.

The value added method requires information about the quantity and value of output and intermediate inputs. Illegal or black-market activities are deliberately hidden from authorities, so producers may not report their transactions and reliable records are usually unavailable. This creates serious measurement and estimation problems. Therefore, lack of reliable data is the main difficulty, making option A correct.

Final or intermediate status is determined by the purpose for which a good is purchased. For example, sugar may be an intermediate good when bought by a bakery to make cakes, but it may be a final good when purchased by a household for direct consumption. Thus, use and buyer matter more than the physical nature of the good. Option A is correct.

A gift is a transfer of money from one person to another and is not payment for a newly produced good or service. Since the value-added method measures the value of current production, the gift itself contributes nothing to output. Including it would incorrectly count a transfer as production.

The value-added method measures production occurring within the domestic territory during the relevant accounting period. Goods made domestically are part of domestic output even when foreign buyers purchase them and consume them abroad. Exports are therefore included; their destination does not change where production took place.

The primary, secondary and tertiary sectors together cover agriculture and extraction, manufacturing and construction, and services. Adding their sectoral value added gives the economy-wide value of production while avoiding the double counting of intermediate goods. It therefore provides a measure of aggregate domestic production.

Value added is calculated by subtracting intermediate consumption from the value of output. If intermediate consumption is incorrectly added instead, the reported figure becomes output plus the input cost rather than output minus the input cost. This produces an inflated value-added estimate and may also create double counting.
