In this Class 12 Economics topic from the chapter “National Income and Related Aggregates,” students learn how national income is estimated through the Value Added or Product Method. The topic explains how to measure the value of final goods and services produced by different sectors, calculate value added at each stage of production, and avoid double counting of intermediate goods. It also connects production data with aggregates such as GDP and helps students understand the role of primary, secondary, and tertiary sectors in national income accounting.
Correct answer: A. The stock of capital on a specified date
Explanation: A stock variable is measured at a specific point in time rather than over a period. The capital stock on a specified date records the accumulated amount existing at that moment. Output during a year, income during a month and investment during a year are flows because each is measured over a time interval.
Correct answer: A. To measure the value added at each stage of production
Explanation: The value-added method measures the contribution made by each producing unit or stage of production. For each unit, value added equals the value of its output minus the value of intermediate inputs purchased from other producers. Adding these contributions gives the value of final production while preventing the same intermediate output from being counted repeatedly.
Correct answer: B. The value of final goods and services produced within the economy
Explanation: The product method calculates national output by adding the value of final goods and services produced during a period, or equivalently by adding value added across producing units. Final output is used to avoid double counting intermediate goods. In a complete national-income calculation, appropriate adjustments may also be made for depreciation, net factor income from abroad, and indirect taxes, depending on the aggregate required.
Correct answer: C. The value remaining after subtracting intermediate consumption from the value of output
Explanation: Value added is the additional value created by a producer during production. It is calculated as the value of gross output minus the cost or value of intermediate consumption used to produce that output. For example, if a bakery sells bread worth ₹1,000 and uses flour and other intermediate inputs worth ₹600, its value added is ₹400. Counting value added prevents double counting.
Correct answer: D. The value of raw materials and services used in production
Explanation: Intermediate consumption is the value of goods and services that a producer purchases and uses up as inputs during the production of other goods and services within the accounting period. Examples include raw materials, fuel, electricity, transport, and business services. These inputs are not final output for this calculation; counting them separately with final products would create double counting.
Correct answer: A. The value of final goods only
Explanation: National-income accounting counts the value of final goods and services, because they represent output purchased for final consumption, investment, or other final use. Alternatively, it can add value added at every stage. Intermediate goods are excluded when final output is counted because their value is already embodied in the final product; counting both would overstate production.
Correct answer: A. Value obtained after subtracting intermediate consumption from value of output
Explanation: Gross value added, or GVA, measures the new value created by a producing unit or sector. It is calculated as the value of output minus the value of intermediate consumption. It is called gross because consumption of fixed capital, commonly known as depreciation, has not yet been deducted.
Correct answer: C. Depreciation
Explanation: Net value added is obtained by subtracting consumption of fixed capital, or depreciation, from gross value added. The formula is NVA = GVA − depreciation. This adjustment removes the value of capital used up during production, so the remaining amount represents the net new value created in the accounting period.
Correct answer: B. All resident producing units
Explanation: Under the product or value added method, domestic income is measured by adding the value added generated by all producing units located within the domestic territory. These units may include households operating businesses, private firms, public enterprises, and government production units. The focus is on production within the territory, not on ownership alone.
Correct answer: C. Net factor income from abroad
Explanation: National product differs from domestic product because it accounts for factor income received from and paid to the rest of the world. To convert a domestic measure into a national measure, net factor income from abroad is added. Thus, National Product = Domestic Product + Net Factor Income from Abroad, with the gross or net basis kept unchanged.
Correct answer: D. Sales and value of change in stock
Explanation: The value of output records the value of goods and services produced during the accounting period. It includes the value of goods sold and the value of the change in inventories or stock, because unsold production is still part of current output. In a simplified expression, value of output includes sales plus the change in stock.
Correct answer: A. 60
Explanation: Value added measures the additional value created by a producer during production. It is calculated by subtracting the value of intermediate goods and services used up from the value of total output. Thus, Value Added = Value of Output − Intermediate Consumption = 100 − 40 = 60. This subtraction prevents the value of inputs from being counted again.
Correct answer: B. 120
Explanation: Gross value added is the value created by a production unit before deducting depreciation. It is found by subtracting intermediate consumption from the value of output: GVA = Value of Output − Intermediate Consumption = 200 − 80 = 120. Intermediate consumption must be excluded because its value has already been included in the output of other producers.
Correct answer: C. 130
Explanation: Net value added shows the value created after allowing for the loss in value of fixed capital used in production. It is calculated by deducting depreciation from gross value added: NVA = GVA − Depreciation = 150 − 20 = 130. Therefore, option C is correct; adding depreciation would incorrectly produce a gross rather than net measure.
Correct answer: A. 85
Explanation: Market price includes net indirect tax in addition to the payment to factors of production. To convert net value added at market price into net value added at factor cost, subtract net indirect tax: NVA at factor cost = NVA at market price − Net Indirect Tax = 100 − 15 = 85. Therefore, option A is correct.
Correct answer: D. Product method
Explanation: The product method calculates domestic product by adding the value added by all producing units in the economy. Since it focuses on the additional value created at each stage of production, it is also known as the value-added method. Intermediate goods are excluded through this approach to avoid double counting.
Correct answer: A. Identifying producing units
Explanation: The first step in the value-added method is to identify the producing units or economic sectors whose output will be measured. Their gross value of output and intermediate consumption are then determined, and value added is calculated. Finally, the relevant values are added without double counting.
Correct answer: B. Adding net factor income from abroad
Explanation: After the value added of producing units is aggregated, the resulting measure represents domestic income or domestic product. To convert it into the corresponding national measure, net factor income from abroad is added. This is because national income includes factor income earned by residents from abroad minus factor income paid to non-residents.
Correct answer: A. Value added of all producing units
Explanation: Under the product method, domestic product is obtained by adding the value added generated by all producing units within the domestic territory. Value added equals the value of output minus the value of intermediate consumption. Adding value added prevents the same intermediate product from being counted repeatedly.
Correct answer: A. When its market value can be estimated
Explanation: A good produced for self-consumption may be included when its value can be reasonably estimated using a comparable market price or another accepted valuation method. Although it is not sold in a market transaction, it represents current production and can therefore contribute to measured domestic product.
Correct answer: B. Value of a productive service
Explanation: A domestic helper who is paid for services provides a market-valued productive service. The salary represents payment for the current service supplied during the accounting period, so its value can be included in national-income measurement. This differs from unpaid household work, which usually lacks an observable market transaction.
Correct answer: A. Because their market value is not clearly recorded
Explanation: Unpaid household services, such as cooking or cleaning for one’s own family, normally do not involve a market transaction or an observable payment. Their monetary value is therefore difficult to measure consistently. National-income accounts generally include marketed services, while excluding these non-market household services.
Correct answer: A. Because it is not current production
Explanation: The value of an old good was counted when the good was originally produced. Adding its full resale price again would count the same production twice and would overstate current national income. However, a current brokerage fee, repair charge, or other newly provided service connected with the resale may be included.
Correct answer: A. Because it is a new productive service
Explanation: The old car itself is not current production, so its resale price is excluded from current national income. The broker, however, provides a current service during the present accounting period. The commission is payment for that newly produced productive service and can therefore be included in national-income measurement.
Correct answer: A. Because it is a financial transaction and not new production
Explanation: The product or value-added method measures the value of newly produced goods and services during an accounting period. Buying and selling existing shares only transfers ownership of a financial asset from one person to another. Since no new good or service is produced through this transaction, its value is not included in domestic product. Brokerage or other financial services connected with the transaction may be counted separately because they represent actual services.
