Methods of calculating national income - Value Added/Product Method

National income measures the value of goods and services produced during the accounting year. An old car was already counted when it was originally produced, so including its full resale price again would count the same production twice. The current sale is mainly a transfer of ownership, not new production. However, any current-year dealer commission, repair service, or other service connected with the sale is included because that service is newly produced.

The old machine itself is not counted as current production because it was produced in an earlier year. The broker’s commission is different: it is payment for a brokerage service actually provided during the current accounting year. That newly produced service adds value to the transaction and is therefore included in national income. It is not a transfer payment and is not intermediate consumption merely because the machine is old.

Product tax is an indirect tax that raises the market price received from or paid by the purchaser above the income accruing to factors of production. Therefore, when output is valued at market prices, product tax must be deducted to convert the figure to factor cost. If subsidies are present, the complete adjustment uses net indirect taxes, meaning indirect taxes minus subsidies. Thus, option B is correct.

The value-added method measures the additional contribution made by each producer or production stage. For every unit, value added equals the value of its output minus the value of intermediate inputs purchased from other units. Summing these additions gives the value of final output while avoiding repeated inclusion of intermediate sales. The method therefore reveals the production structure and provides a systematic safeguard against double-counting.

Value added at each stage equals the firm’s sale value minus the value of intermediate inputs purchased from the previous stage. The additions are ₹25,000, ₹40,000 − ₹25,000 = ₹15,000, and ₹70,000 − ₹40,000 = ₹30,000. Therefore, total value added is ₹70,000, equal to the final product’s value.

A lottery winning is a transfer or windfall receipt, not a payment for producing a good or service during the current period. The value-added method measures the additional value created by productive activities. Including a lottery prize would merely record a transfer of purchasing power and would not represent new output or new value created.

Value of output is calculated as sales plus the change in stock: Value of Output = Sales + Closing Stock − Opening Stock. If closing stock equals opening stock, the change in stock is zero, so value of output is exactly equal to sales. Intermediate consumption and depreciation do not determine this equality.

A new industrial oven is a durable producer asset that remains useful for several production periods. It is therefore classified as fixed capital, not as an intermediate input consumed during one production cycle. For a gross measure, its full purchase is treated as investment; depreciation is deducted only when calculating a net measure.

Imported raw material is an intermediate input because it is used up or transformed during the production of another good. In the value-added calculation, the value of all intermediate consumption, including imported inputs, is deducted from output. This prevents the imported component from being counted as domestic value added and ensures that only value created within the domestic economy is measured.

Government education is generally a non-market service because it is supplied free of charge or without a meaningful market price. National accounting therefore values it at the cost of production, including compensation of employees and other operating costs. A separate profit rate cannot be reliably observed for such a service, so cost-based valuation is used.

Packaging material is used up or transformed as part of the production and marketing process of the manufacturer's product. Because it is purchased by the producer as an input rather than acquired for final satisfaction by a household, its cost is counted as intermediate consumption. It must be deducted from the value of output while calculating gross value added, preventing the same value from being counted twice.

First calculate the value of output by adjusting sales for the change in stock: value of output = sales + closing stock − opening stock = ₹8,00,000 + ₹90,000 − ₹1,20,000 = ₹7,70,000. Then subtract intermediate consumption: GVA₍MP₎ = ₹7,70,000 − ₹3,50,000 = ₹4,20,000. Therefore, option A is correct.

Diesel is consumed in operating the school's buses and is an input used to provide transport services. It is not purchased for direct final satisfaction by the school as a consumer, nor does it create a lasting capital asset. Therefore, in measuring the school's production or service activity, diesel is recorded as intermediate consumption and deducted from the value of output.

Intermediate products are already embodied in the value of the final product. Therefore, adding the full values of wheat, flour, and bread would count the same output repeatedly. National income can avoid this problem either by counting only the value of the final bread or by adding the value added at each stage of production. Both approaches give the same total when measured consistently.

For systematic estimation, producing units are grouped according to the industry or economic sector in which they operate. Common broad divisions include the primary sector, such as agriculture and mining; the secondary sector, such as manufacturing and construction; and the tertiary sector, such as trade and services. Value added is then estimated and aggregated sector by sector.

Domestic income is determined by the location of production, or the domestic territory, rather than by the nationality of the owner. Consequently, value added created by a foreign-owned company operating within India is included in India's domestic product and domestic income. The income may later affect national income differently through factor-income flows to the foreign owners, but the production itself belongs to India's domestic territory.

Under the value added method, gross value added is calculated as the value of output minus intermediate consumption. Raw materials, fuel, power, and services purchased from other producers are intermediate inputs whose value is already included in the output of supplying firms. Deducting them prevents the same production from being counted more than once. Depreciation is deducted later only when net value added is calculated.

National income accounting generally includes market production and measurable services supplied by producing units, such as factory goods, banking services, and the trading service of a shop. Unpaid household activities, including cooking, cleaning, or caring for family members, are normally outside the production boundary because they are not exchanged through the market and have no observed market price.

A trading firm normally resells goods rather than transforming them into new physical products. Its productive contribution is the distribution service it provides, which is measured by the trading margin: the value of sales minus the purchase cost of goods resold, subject to the relevant accounting treatment. Counting the entire sales value would duplicate the value already recorded by producers.

For a trading firm, gross output is represented by the trading margin, not by the entire sale value. The trading margin is ₹1,30,000 − ₹1,00,000 = ₹30,000. Since the firm also incurs ₹8,000 of other intermediate expenses, gross value added is ₹30,000 − ₹8,000 = ₹22,000. Therefore, option C is correct.

Wages are payments to labour for its contribution to production, so they are a component of factor income and value added. In the value added method, only intermediate goods and services bought from other producing units are deducted from gross output. If wages were also deducted, the same labour income would be excluded from the value added generated by the firm.

Net indirect tax is calculated as product taxes minus product subsidies. Therefore, net indirect tax = ₹12,000 − ₹18,000 = −₹6,000. The negative sign is essential because the subsidy is larger than the tax. ₹6,000 is merely the absolute difference and would not correctly show that subsidies exceed taxes.

When a person lives in an owner-occupied house, no actual rent is paid, but the house still provides a housing service. National income accounting therefore estimates the rent that would have been paid for a similar rented house and includes this imputed rent as production. Unpaid household cooking, informal free help, and resale of an old book are not equivalent current production.

Stationery such as paper, ink, and forms is consumed in providing goods or services and normally has a short useful life. When it is used during the production year, its value is an intermediate input and is deducted from output to calculate value added. Merely storing it does not mean it has been consumed, while a permanent machine would be capital formation. Therefore A is correct.

A bonus is additional compensation paid to employees for the labour services they provide. It is therefore part of compensation of employees, which is a factor payment and a component of value added. Intermediate consumption consists of goods and services used up in production, such as raw materials or electricity, not payments made to labour. Hence option A is correct.
