Methods of calculating national income - Income Method
राष्ट्रीय आय की गणना की विधियाँ – आय विधि
In Class 12 Economics, this topic explains how national income is estimated through the Income Method, one of the approaches covered under National Income and Related Aggregates. Students learn to add factor incomes earned from production, including compensation of employees, rent, interest, profits and mixed income of the self-employed. The topic also clarifies the treatment of net factor income from abroad, transfer payments and depreciation, while highlighting the need to avoid double counting and distinguish factor income from non-factor receipts.
Practice questions
01 While estimating national income by the income method, which of the following is included in compensation of employees?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Employer’s contribution to an employee’s provident-fund account
Explanation: Compensation of employees includes wages and salaries plus employers’ social-security contributions made for their employees. A provident-fund contribution is connected with the employee’s employment and is therefore included. Old-age pensions and unemployment allowances are transfer payments, while dividends are property income. Hence, option A is correct.
02 Income earned by a normal resident working within the domestic territory will be included in which of the following?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Both domestic income and national income
Explanation: Domestic income measures factor income generated within a country’s domestic territory, regardless of whether the factor belongs to a resident or a non-resident. National income measures factor income accruing to normal residents, whether earned inside or outside the territory. A normal resident working domestically satisfies both conditions, so the income enters both aggregates. Option A is correct.
03 Why are capital gains treated separately from normal production income in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because they often arise from changes in asset prices rather than from current productive services
Explanation: A capital gain usually results from an increase in the market price of an existing asset, such as land, a house, or old shares. It does not necessarily represent income generated by current production or by supplying a factor service during the accounting period. Consequently, it is kept separate from normal factor income in the income method. Option A is correct.
04 While estimating national income by the income method, which item is included in compensation of employees?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Employer’s contribution to an employee’s provident-fund account
Explanation: Compensation of employees includes direct wages and salaries as well as employers’ contributions to social-security schemes, including provident funds. An old-age pension is a transfer payment; a capital gain comes from an asset-price change; and lottery money is a windfall receipt. None of these is payment for current employee service. Therefore, option A is correct.
05 When will commission received by an employee be included in compensation of employees under the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. When it is received for employment service
Explanation: Commission is included in compensation of employees when it is paid in return for services performed as part of an employment relationship. It then represents labour income generated by current production. Lottery winnings and donations are transfer or windfall receipts, while money from selling old shares is an asset transaction or capital gain, not employee compensation. Hence, option A is correct.
06 Which check is most necessary before arriving at the final result under the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Check whether all included items are factor incomes generated by production
Explanation: The income method totals factor incomes generated by current production, such as compensation of employees, rent, interest, profit, and mixed income, subject to the relevant accounting treatment. Consumption expenditure belongs to the expenditure method, while loans, donations, and many transfers are not payments for current production. Including such items would produce an incorrect estimate.
07 If domestic factor income is ₹3,600 crore and net factor income from abroad is ₹240 crore, what is national income?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. ₹3,840 crore
Explanation: National income is obtained by adding net factor income from abroad to domestic factor income: National Income = Domestic Factor Income + NFIA. Therefore, ₹3,600 crore + ₹240 crore = ₹3,840 crore. Since NFIA is positive, it increases domestic factor income to the national-income figure. Hence, option C is correct.
08 What does negative net factor income from abroad indicate under the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Factor income paid to abroad is greater than factor income received from abroad
Explanation: Net factor income from abroad is calculated as factor income received from abroad minus factor income paid to abroad. A negative value therefore means that payments made to foreign factors exceed income received by domestic residents from factors abroad. Consequently, national income, which equals domestic income plus NFIA, is lower than domestic income.
09 Under the income method, how should the income of an owner-operated small shop generally be classified?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Mixed income
Explanation: The owner of a small shop commonly contributes labour, uses personal or business capital, organises the activity, and bears entrepreneurial risk. The total return cannot usually be separated accurately into wages, interest, rent, and profit. Therefore, the income is classified as mixed income, which combines returns to the owner’s labour, capital, and enterprise.
10 Which form of profit included in operating surplus is treated as part of a company's income?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Undistributed profit
Explanation: Undistributed profit is the part of a company’s profit that is retained instead of being paid to shareholders as dividends. It is nevertheless generated from the firm’s production and business activity. Under the income method, profits, including retained or undistributed profits, form part of operating surplus and are counted as factor income. The other options are transfer receipts or personal gifts, not operating profit.
11 If compensation of employees is ₹1,250 crore, operating surplus is ₹980 crore and mixed income is ₹370 crore, what will be domestic income?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. ₹2,600 crore
Explanation: Using the income method, domestic income is calculated by adding compensation of employees, operating surplus and mixed income. Therefore, domestic income = ₹1,250 crore + ₹980 crore + ₹370 crore = ₹2,600 crore. No deduction is required because all three figures are already income components generated within the domestic territory. Hence, option B is correct.
12 If national income is ₹4,100 crore and domestic income is ₹4,350 crore, what is net factor income from abroad?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. -₹250 crore
Explanation: The relationship is: National income = Domestic income + Net factor income from abroad. Rearranging gives NFIA = National income − Domestic income. Thus, NFIA = ₹4,100 crore − ₹4,350 crore = −₹250 crore. The negative sign means factor payments made to the rest of the world exceeded factor income received from abroad by ₹250 crore. Therefore, option B is correct.
13 What precaution applies when treating a private doctor's clinic income as mixed income in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It is self-employment income where labour and capital may be hard to separate
Explanation: A self-employed doctor may simultaneously provide medical labour, use personally owned equipment and premises, and organise the business. The total clinic receipt therefore combines returns to labour, capital and entrepreneurship. Since these components cannot always be separately measured from accounts, the income is classified as mixed income. It should not automatically be treated as salary, a transfer, or a tax.
14 In the income method, dividend of a company should be understood as what rather than entirely new production income?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Distributed part of company profit
Explanation: A dividend is the portion of a company’s profit distributed to its shareholders. The profit was generated through the company’s production and business operations before distribution. Therefore, the dividend is not a separate, additional act of production; it is a distribution of an income component already recorded as profit. This treatment prevents the same production income from being counted twice.
15 If factor income from abroad is ₹480 crore and factor income paid abroad is ₹520 crore, what will be net factor income from abroad?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. -₹40 crore
Explanation: Net factor income from abroad is calculated as factor income received from abroad minus factor income paid to the rest of the world. Therefore, NFIA = ₹480 crore − ₹520 crore = −₹40 crore. Because payments to foreign factors are greater than receipts from domestic factors working abroad, the balance is negative. Hence, option B is the correct answer.
16 What is the deeper reason for not treating subsidy as factor income in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It is not a reward received by a factor for service
Explanation: Factor income is payment made to a factor of production—such as labour, land, capital or entrepreneurship—in return for its productive service. A subsidy is financial assistance provided by the government to reduce costs or support producers or consumers. It is not payment for a separately supplied factor service. Therefore, subsidy is treated as a transfer or policy-related adjustment, not as factor income in the income method.
17 Why can a lottery agent's commission be included even though lottery winnings are excluded in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. The commission is a payment for a selling service, whereas the winning is a transfer-type receipt and not payment for current production.
Explanation: The income method counts factor incomes generated by current production, such as wages, rent, interest, profit, and income from services. A lottery agent performs a distribution or selling service, so the commission is remuneration for that productive service and may be included. A lottery prize, however, is not paid in exchange for a currently supplied productive service; it is generally treated as a transfer-type receipt and is excluded from factor income. Thus, the two receipts have different economic bases.
18 Why can managerial salary and profit received by the same owner be shown separately in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. They may be separate rewards for labour or management service and entrepreneurship.
Explanation: The income method classifies income according to the factor or service that generates it. If an owner actively manages the enterprise, the payment identified as managerial salary is remuneration for labour or management services. The residual profit is the return to entrepreneurship and risk-bearing. The same individual can supply more than one factor service, so receiving both forms of income is possible. Separating them improves classification and prevents the entire amount from being incorrectly placed in only one category.
19 Rent received by a resident household from property abroad will come under which adjustment in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Factor income from abroad
Explanation: Rent is a return to the factor of land or property. When a resident household receives rent from property located abroad, the income accrues to a resident from an external economic territory. It is therefore recorded as factor income from abroad. In moving from domestic income to national income, such receipts contribute to net factor income from abroad, after subtracting factor income paid by the country to non-residents. Hence, option A is correct.
20 How can profit paid to a non-resident within the country be adjusted in national income under the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It is treated as factor income paid abroad and deducted when calculating national income.
Explanation: The physical location of payment does not determine the recipient's economic residence. If a domestic enterprise generates profit but pays it to a non-resident owner, that profit is part of domestic income because production occurred within the domestic territory. However, it is not part of the income accruing to residents. Therefore, it is recorded as factor income paid abroad and deducted, usually through the net factor income from abroad adjustment, when deriving national income.
21 What is the correct difference between the current salary of a government employee and a government pension in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Salary is a reward for current service, whereas pension is generally a transfer payment not linked to current production.
Explanation: A government employee's current salary is paid in exchange for labour or administrative services supplied during the current period. Since it is remuneration for current production-related service, it is included as compensation of employees in the income method. A pension, in contrast, is normally paid because of past service, retirement status, or a social entitlement and is not payment for work performed in the current period. It is therefore generally treated as a transfer payment and excluded from factor income.
22 Which principle is used while estimating the value of goods produced for self-consumption in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. The principle of imputed market value
Explanation: Goods produced for self-consumption are not sold through an observed market transaction, but their production still represents current economic activity. To include their contribution consistently in national income, the value is imputed using the price that a comparable good would command in the market, or an appropriate equivalent valuation. This prevents non-market production from being omitted merely because the producer consumes it rather than selling it. Therefore, option A is correct.
23 What is the correct broad structure of compensation of employees in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Cash wages, wages in kind and employer social contributions
Explanation: In the income method, compensation of employees means the total payment made to workers for their current labour services. It includes wages and salaries paid in cash, payments or benefits provided in kind, and the employer’s contribution to social security or similar schemes. Rent, interest and profit are separate components of factor income, while gifts, grants and loans are not payment for current employee services. Therefore, option A gives the complete structure.
24 What will be the effect of wrongly adding transfer income in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. National income may be overestimated
Explanation: Transfer income, such as a pension, scholarship or unemployment allowance, is received without providing a current factor service or producing a corresponding current output. It is therefore not included as factor income in the income method. If it is added mistakenly, the measured income total includes a non-production receipt and may become higher than the true national income. Therefore, option A is correct.
25 What is the main reason for keeping capital gains or losses separate in the income method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It is a change in asset value, not income from current production
Explanation: A capital gain or loss arises because the market value of an existing asset changes, for example when land, shares or a building becomes more or less valuable. This change does not necessarily represent a newly produced good or a current factor service during the accounting period. National income measures income generated by current production, so capital gains and losses are kept separate. Hence, option A is correct.
