Methods of calculating national income - Value Added/Product Method

Domestic territory defines the geographical area whose production is counted in domestic product. Under the value-added method, the value added generated by production units located within this territory is added, regardless of whether the producers are residents or foreigners. This concept is different from national territory or ownership of factors. Net factor income from abroad is used later when converting a domestic aggregate into a national aggregate.

Agricultural production is included when it represents economic output produced during the accounting period. The value-added method counts the value created by agricultural activities, such as growing crops or producing livestock, after deducting the value of intermediate inputs used in production. It does not matter whether the output is sold in a market or retained by the producer for self-consumption, provided it is measurable and falls within the production boundary.

The service sector creates economic value even though many services are intangible and cannot be stored like physical goods. In the value-added method, the value of services produced by businesses, professionals, transport providers, banks, schools, hospitals and other units is counted after deducting the intermediate services and inputs used. Therefore, service-sector value added is added along with value added from agriculture and industry.

The value-added method measures the additional value created by each production unit or stage. It is calculated as the value of an enterprise’s output minus the value of intermediate goods and services purchased from other producers. Adding these increments across the economy gives the value of final production while avoiding the repeated counting of inputs such as raw materials. Thus, option A correctly states the central idea of the method.

Double counting occurs when the value of an intermediate product is added separately even though it is already included in the price of the final product. Wheat is used to make bread, so the price of the wheat is embodied in the bread’s final price. Adding the complete prices of both wheat and bread counts the same production more than once and overstates national output. The problem is avoided by counting only final output or each stage’s value added.

The mill’s value added equals the value of its output minus the value of intermediate consumption. The mill sells flour worth 80 and uses wheat worth 50 as an intermediate input. Therefore, mill value added = 80 − 50 = 30. The figure 80 is the mill’s gross output value, while 50 is not added again as new value because it was created by the farmer. Adding 50 and 80 would cause double counting.

Gross value added is calculated by subtracting intermediate consumption from the total value of output. Using the formula, GVA = value of output − intermediate consumption = 500 − 300 = 200. The amount 300 is only the value of inputs consumed during production, and 500 is the gross output value before deduction. Therefore, 200 correctly represents the new value created by the production unit.

Net value added is obtained by deducting depreciation from gross value added. Depreciation represents the loss in value or consumption of fixed capital during production. Therefore, NVA = GVA − depreciation = 90 − 10 = 80. Adding depreciation would incorrectly move from a net measure to a gross measure, while using 90 without adjustment would simply reproduce gross value added rather than net value added.

To convert value added at market price into value added at factor cost, net indirect tax must be deducted. Market prices include indirect taxes and exclude subsidies, whereas factor cost reflects the payments received by factors of production. Therefore, value added at factor cost = value added at market price − net indirect tax = 250 − 30 = 220. Hence, option B is correct.

An increase in stock represents goods that have been produced during the current period but have not yet been sold. Since production has already taken place, the value of these unsold goods is included in the value of output under the value-added or product method. It is not a tax or an import, and it is not automatically subtracted.

Value added is the additional value created by a producer or production unit during the process of production. It is calculated as the value of output minus the value of intermediate consumption. Thus, it measures the new contribution made to production and forms an important basis for estimating income generated by productive activity.

The value of a final good normally includes the value of the intermediate goods used to produce it. If the intermediate goods and the final good were both counted separately, the same production value would be included more than once. Counting only final goods, or alternatively adding value at each stage, prevents this double-counting problem.

The main precaution is to prevent intermediate goods from being counted repeatedly at different stages of production. This can be done by counting only final goods or by adding the value added by each production unit. Financial transactions, second-hand goods, and gifts do not represent current production and should not be included as current output.

Under the value-added or product method, the value created by a production unit is calculated as the value of its output minus the value of intermediate goods and services used in producing it. This prevents the value of inputs from being counted repeatedly. Hence, option A gives the correct formula.

The product method measures the value of final goods and services produced during a period. Intermediate goods are not added separately because their value is already included in the price of final goods. Counting both would cause double counting and overstate national income. Therefore, option B is correct.

Intermediate goods are inputs used to produce other goods, so their value is transferred into the value of the final product. If their value were added separately along with the final product, the same economic value would be counted more than once. The value-added method avoids this double counting; therefore, option A is correct.

Gross value added is calculated as the value of output minus the value of intermediate consumption. The value of output is the market value of goods and services produced by the unit, while intermediate consumption is the value of goods and services used up during production. The difference represents the new value created by the producing unit. Since depreciation is not deducted in GVA, option B is correct; deducting depreciation would give net value added instead.

Gross value added is measured before accounting for the wear and tear of fixed capital. Depreciation, also called consumption of fixed capital, is subtracted from gross value added to obtain net value added. The relationship is NVA = GVA − depreciation, so option A is correct.

The conversion from value added at market price to value added at factor cost requires subtracting net indirect taxes, which equal indirect taxes minus subsidies. Thus, value added at factor cost = value added at market price − net indirect taxes. Depreciation is used to convert gross measures into net measures, not market price into factor cost. Hence, option B is correct.

Net indirect taxes are calculated by subtracting subsidies from indirect taxes: net indirect taxes = indirect taxes − subsidies. If indirect taxes are greater than subsidies, the difference is above zero. Therefore, net indirect taxes will be positive. For example, if indirect taxes are ₹100 and subsidies are ₹30, net indirect taxes equal ₹70. Hence, option C is correct.

Net indirect taxes are obtained by subtracting subsidies from indirect taxes: net indirect taxes = indirect taxes − subsidies. When subsidies exceed indirect taxes, the subtraction produces a value below zero, so net indirect taxes are negative. For instance, taxes of ₹40 and subsidies of ₹70 give net indirect taxes of −₹30. Thus, option B is correct.

The value-added method measures the value of goods and services produced during the current accounting period. A newly produced book represents current production, so its value, or the value added at each stage of its production, may be included. An old book, a share purchase, and a personal gift do not represent newly produced output. Therefore, option B is correct.

The old good was produced and counted in national output during an earlier period, so its entire resale value must not be counted again. However, a broker or agent may provide a new service in the current period. The fee or commission paid for that service is current production and can be included. Therefore, option B is correct.

Buying a financial asset, such as a share or a bond, generally transfers ownership of an existing financial claim from one person to another. The transaction itself does not create a new physical good or a newly produced service. Since the value-added method counts current production, the purchase price of the financial asset is excluded. Hence, option A is correct.

Domestic product measures the value of final goods and services produced within a country’s domestic territory during a specified period, regardless of whether the producers are residents or foreigners. Under the value-added method, the value added by all producing units within that territory is summed. Therefore, option A is correct.
