Methods of calculating national income - Value Added/Product Method

Correct answer: A. Because changes in stock may also be part of current output

Explanation: Sales do not always equal the total output produced during an accounting year. A firm may produce goods that remain unsold and are added to inventory, or it may sell goods from opening stock produced earlier. For current output, the product method therefore considers sales together with the change in stock, avoiding an incorrect measurement of production.

Correct answer: B. The value of output will be understated

Explanation: An increase in stock means that some goods were produced during the current period but have not yet been sold. The product method measures current output by adding the change in stock to sales. If the increase is omitted, the unsold part of current production is excluded, so the calculated value of output becomes lower than the true value. Thus, it is understated.

Correct answer: A. Value of output, intermediate consumption, and required adjustments

Explanation: A value-added problem should first be organised around the value of output and intermediate consumption, because value added equals output minus intermediate consumption. After that, the solver should identify the required adjustments, such as depreciation, net indirect taxes, and net factor income from abroad, depending on the aggregate being requested. This sequence prevents double counting and calculation errors.

Correct answer: A. 680

Explanation: Under the value-added or product method, the value of output includes goods sold during the period as well as the increase in inventories. Therefore, value of output = sales + increase in stock = 600 + 80 = 680. The figure 600 counts only sales and ignores unsold production added to stock. Thus, option A is correct.

Correct answer: B. 830

Explanation: A decrease in stock means that sales exceeded the goods produced during the current period; some goods sold came from earlier inventories. Hence, current value of output is calculated as sales minus the decrease in stock: 950 − 120 = 830. Option 950 ignores the inventory adjustment, so option B is correct.

Correct answer: C. 750

Explanation: Gross value added measures the value created by a producer or sector. It is calculated by subtracting the value of intermediate goods and services used in production from the total value of output. Thus, GVA = 1200 − 450 = 750. Adding the figures would double-count inputs, so option C is the only correct answer.

Correct answer: D. 825

Explanation: Net value added is obtained by deducting consumption of fixed capital, commonly called depreciation, from gross value added. The calculation is NVA = GVA − depreciation = 950 − 125 = 825. Gross value added itself is 950, but it does not account for the loss of fixed capital. Therefore, option D is correct.

Correct answer: B. ₹575

Explanation: Net value added at market price is calculated by adding net indirect taxes to net value added at factor cost. Net value added at market price = Net value added at factor cost + Net indirect tax = ₹540 + ₹35 = ₹575. Therefore, option B is correct. The addition is required because market prices include indirect taxes, whereas factor cost excludes them.

Correct answer: A. 600

Explanation: When stock increases, the increase is added to sales to obtain the value of output: 1000 + 150 = 1150. Gross value added is 1150 − 500 = 650. Since the question asks for net value added, depreciation must also be deducted: 650 − 50 = 600. Thus, option A is correct; 650 is only the gross value added.

Correct answer: B. 650

Explanation: A decrease in stock means that the value of output is lower than sales. Therefore, value of output = sales − decrease in stock = 1200 − 100 = 1100. Gross value added is value of output minus intermediate consumption: 1100 − 450 = 650. Hence, option B is correct. Depreciation is not deducted because the question asks for gross value added.

Correct answer: A. 1720

Explanation: First convert gross value added at market price into net value added at market price by subtracting depreciation: 2000 − 180 = 1820. Net indirect tax equals indirect tax minus subsidy, so it is 160 − 60 = 100. To convert market price to factor cost, subtract net indirect tax: 1820 − 100 = 1720. Therefore, option A is correct.

Correct answer: D. Add net factor income from abroad

Explanation: Domestic product measures production within the economic territory, whereas national product measures production income attributable to the country’s normal residents. The difference is adjusted through net factor income from abroad. Therefore, national product = domestic product + net factor income from abroad. Intermediate consumption, depreciation, and total sales do not make this domestic-to-national adjustment. Option D is correct.

Correct answer: A. It will be included as factor income received from abroad

Explanation: National income is based on the income of normal residents, not merely on production occurring within domestic territory. Profit earned abroad by an Indian resident company is factor income received from abroad and is included in national income. It is not intermediate consumption, depreciation, or an indirect tax. Therefore, option A is correct and contributes to the net factor income from abroad adjustment.

Correct answer: A. In India’s domestic product

Explanation: Domestic product is measured according to the geographical location of production, not according to the nationality or ownership of the producer. Therefore, value added generated by a foreign company inside India’s domestic territory is included in India’s GDP or domestic product. The income may later be relevant for national income adjustments, but the production itself belongs to domestic product.

Correct answer: A. Because the wages are earned outside the domestic territory

Explanation: Domestic product records the value of goods and services produced within a country’s domestic territory during a period. Wages earned abroad arise from production outside that territory, so they are not part of domestic product. However, because the earner is a resident, such factor income may be considered while converting domestic income into national income through net factor income from abroad.

Correct answer: A. Because it is not new production of the current year

Explanation: The building itself was produced and counted in national income when it was originally constructed. A resale in a later year is only a transfer of ownership of an existing asset, not newly produced output for that year. Adding the full sale price again would count the same building twice. However, any current-year brokerage, legal, or repair service connected with the sale may be included because those services are newly produced.

Correct answer: B. Because it is a productive service provided in the current year

Explanation: The old house itself is not current production, so its entire resale value is excluded from the current year’s national income. The property agent, however, provides a real brokerage service during the current year and receives a fee for arranging or facilitating the transaction. That fee represents the value of a newly produced service and can therefore be included in current output and national income.

Correct answer: A. It is a financial claim, not current production

Explanation: Buying a bond is a financial transaction that transfers or creates ownership of a financial claim; it does not produce a new good or service during the current period. The purchase price therefore cannot be treated as value added. Any brokerage, advisory, or other financial service actually provided in connection with the transaction may be counted separately as service output, but the bond’s principal value is excluded.

Correct answer: B. The brokerage service charge

Explanation: The purchase of shares is a financial transaction because ownership of a financial asset changes hands; it does not represent current production. However, the bank performs a current brokerage service and receives a service charge for it. The value of that service is included in national income, while the principal value of the shares, the investor’s saving, and the old share value are not included as current output. This illustrates the distinction between financial transactions and productive services.

Correct answer: A. Because it is a transfer payment, not payment for a factor service or current production

Explanation: A government scholarship is a transfer payment. The recipient receives money without supplying a current good or productive service to the government in exchange for that payment. The product or value-added method counts the value of goods and services produced during the current period, not payments that merely redistribute purchasing power. Intermediate goods are excluded for a different reason: excluding them prevents double counting. Therefore, option A is correct.

Correct answer: A. Because the house provides a housing service

Explanation: An owner-occupied house provides a continuing housing service to its owner even though no rent is actually paid in the market. National accounting therefore imputes, or estimates, the rent that a comparable house could have earned. Including this imputed rent helps treat owner-occupied and rented housing consistently and records the value of the current housing service. The house itself is an asset, but the included amount is the service flow, not the asset’s purchase price.

Correct answer: A. Because it is not a market transaction with a recorded market value

Explanation: Cooking for one’s own household is a useful service, but it is normally unpaid and does not pass through a market. Since there is no observable transaction or reliable recorded price, national accountants generally exclude this household service from measured national income. This does not mean that the activity has no economic usefulness; it means that standard national accounts focus mainly on market production and services for which a reasonable monetary value can be established.

Correct answer: A. Because it is a paid productive service

Explanation: When a domestic helper is hired and paid for cooking, cooking becomes a market-oriented service with an observable monetary payment. The helper supplies labour, and the payment represents the value of a current productive service. Consequently, the service can be included in measured national income, unlike the same activity performed unpaid within a household, which usually has no recorded market value. The relevant item is the service provided during the period, not an old good, gift, or subsidy.

Correct answer: A. At its estimated market value

Explanation: Crop produced by a farmer remains economic production even when part of it is consumed by the farmer’s own family rather than sold in a market. To measure the output consistently, national accounts assign the self-consumed crop an estimated market value, usually based on the price of a comparable crop in the relevant market. Recording it at zero would understate production and income. The value is included because output was produced, not because a sale necessarily occurred.

Correct answer: A. Intermediate consumption is greater than the value of output

Explanation: Gross value added is calculated as the value of output minus intermediate consumption: GVA = output value − intermediate consumption. Therefore, it becomes negative when the cost or value of intermediate inputs exceeds the value of the output produced during the period. Option B would produce positive value added, not negative value added. The result does not mean that the unit produced only final goods or that depreciation was necessarily omitted; those statements do not explain the sign of value added.
