Methods of calculating national income - Income Method

Salary is compensation paid to labour, which is a factor of production. Under the income method, national income is calculated by adding factor incomes such as wages and salaries, rent, interest, and profit. Salary is therefore an income-method component, not a direct component of expenditure on final goods and services.

An insurance claim is normally compensation for a loss, damage, or insured event rather than a reward for supplying labour, land, capital, or entrepreneurship. Therefore, the claim itself is not factor income. Treating the entire receipt as wages, rent, interest, or profit would overstate income generated by current productive activity in the income method.

A self-employed farmer may supply labour, use owned land and capital, and organise production as an entrepreneur at the same time. Since the total receipt cannot be reliably separated into wages, rent, interest, and profit, it is recorded as mixed income of the self-employed. This avoids arbitrary division in the income method.

Wages earned by a resident from work performed abroad are factor income received from abroad. They therefore form a positive part of net factor income from abroad, provided the income is not already included in domestic production. NFIA is used to adjust domestic income to obtain national income: National Income = Domestic Income + NFIA.

Wages earned inside the country by a foreign resident are factor income paid to the rest of the world. They are included in domestic income because production occurs within the domestic territory, but they reduce net factor income from abroad. Thus this payment affects NFIA negatively when national income is derived from domestic income.

Under the income method, national income is calculated by adding the factor incomes generated during the production of goods and services. The principal components are compensation of employees, rent, interest, profit and mixed income of the self-employed, subject to the relevant national-income adjustments. The value of final goods belongs to the product or value-added approach, while taxes and imports alone do not measure factor income. Therefore, option B is correct.

Wages and salaries are payments made to employees in return for their labour services, so they are classified as compensation of employees. This is a major component of factor income in the income method. Property income generally refers to rent and interest, transfer income is received without providing a current productive service, and product tax is a government levy rather than income paid to employees. Hence, option B is correct.

Rent is the return received by the owner of land or other natural resources when these resources are made available for production or use. In the standard factor-reward classification, land earns rent, labour earns wages, capital earns interest, and the entrepreneur earns profit. Therefore, rent is factor income associated with land. It may also be described as property income in national-income accounting, but among the given factors, option A is the unambiguous answer.

Interest is the return earned by the owner of capital for allowing capital to be used in production. In the factor-income classification, land receives rent, labour receives wages, capital receives interest, and the entrepreneur receives profit. The question refers to the factor receiving the return, not to the borrower who pays it. Consequently, interest represents capital income and option B is correct under the income method.

Profit is the return earned by the entrepreneur for organising production, making business decisions, bearing uncertainty and taking risks. In the standard factor-reward framework, labour receives wages, land receives rent, capital receives interest and the entrepreneur receives profit. Although profit may contain several economic elements in practice, its primary factor association in school-level national-income analysis is entrepreneurship. Therefore, option C is correct.

The income method measures factor incomes generated within the domestic territory, such as compensation of employees, rent, interest, profit, and mixed income. Net factor income from abroad is not part of domestic income because it represents the difference between factor income received from abroad and factor income paid to foreigners. It is added to domestic income only when national income is calculated.

Factor income is earned by providing a factor of production—labour, land, capital, or entrepreneurship—in the current production process. Rent, profit, and a production-related bonus are factor incomes. A pension received as a transfer payment is not made in exchange for a current productive service, so it is excluded from factor income and national income.

A self-employed doctor supplies labour and also uses personal capital, equipment, and entrepreneurial effort. Because the separate shares of labour income, capital income, and entrepreneurial income cannot usually be identified accurately, the total earning is called mixed income of the self-employed. It is included as a factor-income component in the income method.

Compensation of employees includes wages and salaries in cash or kind, together with employers’ social contributions made on behalf of employees. These contributions are connected with the employee’s service and form part of labour compensation. Lottery winnings, sale proceeds of an old car, and donations are not payments for current factor services and are therefore excluded.

The income method estimates national income by summing factor incomes generated through current production, such as compensation of employees, rent, interest, profit, and mixed income, with the appropriate adjustment for net factor income from abroad. Transfer receipts are not payments for current production, and adding intermediate sales may cause double counting. Therefore, all relevant factor incomes must be correctly recorded.

Under the income method, domestic factor incomes are added: compensation of employees, rent, interest, profit, and mixed income. To convert domestic income into national income, net factor income from abroad is added. Thus, option A gives the appropriate simplified formula. The other options represent incomplete or unrelated combinations and do not measure national income by the income method.

Undistributed profit is the part of a company’s profit that is retained rather than paid as dividends. It is still generated by the production activity of the enterprise and represents income accruing to the enterprise or its owners. Consequently, it is included in the profit component of factor income under the income method, even though it is not distributed to shareholders.

Corporate profit tax is assessed on the profits earned by corporations. In national-income accounting, it is treated as part of corporate or enterprise profit within operating surplus, rather than as compensation of employees or mixed income. The tax is recorded with profit because it is a claim on the enterprise’s generated surplus before the remaining profit is distributed or retained.

Domestic income is based on the location of production. Therefore, factor income generated within the domestic territory is included in domestic income, regardless of whether the producing unit is resident or foreign-owned. A foreign company’s profit earned inside the country is included in domestic income. It may be excluded when moving to national income if the profit is treated as factor income accruing to non-residents.

Wages earned by an Indian resident while working abroad are factor income received from the rest of the world. Such receipts, after subtracting factor payments made to foreign residents within India, form part of net factor income from abroad (NFIA). NFIA is added to domestic income to obtain national income. Therefore, option B is correct.

The income method measures factor incomes generated through current production, such as wages, rent, interest, profit, and mixed income. Money obtained through theft or gambling is not a payment for supplying a factor of production and does not represent newly produced goods or services. Hence it is excluded from national income, making option A correct.

The income method estimates national income by adding factor incomes, not by adding the sale proceeds of every good. Intermediate goods are used in producing final goods, so counting their sale proceeds along with final output can count the same economic value more than once. Therefore, intermediate-goods sale proceeds are excluded from this calculation and option B is correct.

Unpaid household services, such as cooking, cleaning, and caring for family members, generally do not involve a market transaction or an observable monetary payment. Since national-income accounting records marketed production and measurable factor incomes, the value of such self-provided services is usually excluded. Hence option A is the best answer.

A self-employed private doctor provides professional labour and may also use personal capital, equipment, and premises in delivering medical services. The total fee cannot be separately divided with certainty into labour income, capital income, and entrepreneurial profit. Therefore, it is classified as mixed income under the income method. Option A is correct.

A dividend is a distribution of the profit earned by a company to its shareholders. In the income method, profit is included in operating surplus, which is a return to the entrepreneur or owner of capital. The dividend itself is not counted as a separate new income item, because doing so could cause double counting. Wages belong to compensation of employees, mixed income belongs mainly to self-employed persons, and product tax is a government receipt.
