Methods of calculating national income - Income Method

A lottery prize is not factor income because it is not earned by providing a productive service through labour, land, capital, or entrepreneurship. It is a windfall receipt rather than income generated by current production. Wages, rent, and interest are factor incomes because they are returns for labour, land, and capital services respectively.

Pension is generally treated as a transfer payment because it is not received in exchange for a productive service rendered during the current accounting period. The income method includes factor incomes generated by current production, such as wages, rent, interest, and profit. Therefore, a regular pension is normally excluded from factor income.

Factor income is earned by providing the services of a factor of production. An employee's salary is received in exchange for labour, so it is factor income and is included under compensation of employees. A prize, donation, or lottery receipt is generally received without providing a current productive service and is therefore not factor income.

Medical facilities, housing, transport, or other benefits provided by an employer are treated as benefits in kind. Their value is included in compensation of employees because the employee receives them as part of the employment relationship. Imports, net exports, and gross capital formation are unrelated aggregates and do not represent employee remuneration.

Under the income method, factor income is obtained by adding the returns received by the factors of production. Therefore, total factor income equals wages + rent + interest + profit = 300 + 80 + 70 + 150 = 600. Wages reward labour, rent rewards land, interest rewards capital, and profit rewards entrepreneurship. Hence, option B is correct.

Domestic income is the sum of factor incomes generated within the domestic territory during an accounting period. In the income method, it is calculated as compensation of employees + operating surplus + mixed income. This total corresponds to NDP at factor cost. Consumption, imports, loans, taxes, donations, and pensions do not form this basic domestic-income formula.

Using the income method, domestic income is calculated by adding compensation of employees, operating surplus, and mixed income. Thus, domestic income = 450 + 250 + 100 = 800. The amount 750 results from omitting mixed income, while 700 omits both mixed income and part of the given components. Therefore, option C is the correct answer.

A self-employed shopkeeper usually performs several roles at the same time: worker, owner of capital, and entrepreneur. Because the separate amounts attributable to labour, capital, and entrepreneurship cannot be identified reliably, the combined earning is called mixed income of the self-employed. Compensation of employees applies to hired workers receiving wages or salaries.

Rent is factor income because it is received as a return for providing land, buildings, or other property for productive use. In contrast, an old-age pension, lottery prize, and scholarship are generally transfer payments: they are received without providing a current productive service in exchange. Therefore, rent is the only factor income among the options.

A scholarship is normally provided to support education and is not paid in exchange for labour, land, capital, or entrepreneurial services. It is therefore classified as transfer income, or a transfer payment, and is excluded from factor income in national-income accounting. Wages, rent, and interest are factor incomes because each is a return for a productive factor.

The sale of an old house is a transaction involving an asset that was produced in an earlier period. The sale generally transfers ownership from one person to another and does not represent new production during the current period. Consequently, its sale value is not counted as current factor income in the income method. Only current services, such as brokerage, may be included.

Profit is the return earned by an entrepreneur for organising production, making business decisions, coordinating resources, and bearing uncertainty and risk. Therefore, the profit of a domestic company owner is classified as entrepreneurial income under the income method. Labour income is wages or salaries, land income is rent, and transfer income is received without a current productive service.

Interest credited on a savings account is the return received for allowing a bank to use deposited funds. Money used in this way represents financial capital, so the interest is classified as income from capital and is included as factor income, subject to the accounting framework. Rent is the return on land, wages are the return on labour, and donations are transfers.

A self-employed small shopkeeper performs several roles at the same time. The shopkeeper supplies personal labour, manages the business and bears entrepreneurial risk, but it is difficult to separate the returns to labour, management and entrepreneurship. Therefore, the combined earnings are called mixed income. A government salary is compensation of employees, a bank loan is a financial receipt, and a scholarship is generally a transfer receipt.

Unemployment assistance is a transfer payment made by the government to support a person who is not currently providing a productive factor service. It is not payment for labour, land, capital or entrepreneurship. Since the income method adds factor incomes generated through current production, unemployment assistance is excluded from national income under this method. It may be received by a household, but it does not represent newly produced output.

Factor income is the income earned by the factors of production—labour, land, capital and entrepreneurship—for supplying productive services. Indirect taxes such as GST or excise duty are collected by the government on goods and services; they are not paid to factors as rewards for their services. Consequently, they are not included when factor income is initially measured by the income method, although tax adjustments may be needed when moving between factor-cost and market-price aggregates.

A self-employed person usually contributes labour, capital and entrepreneurial effort to the same business. The total income received cannot be separately divided into wages, rent, interest and profit using ordinary records. Therefore, it is classified as mixed income. This treatment is especially common for small farmers, shopkeepers and proprietors.

In a small owner-operated business, the owner often performs the work, supplies or owns capital, and makes entrepreneurial decisions. The resulting income combines returns to several factors and cannot be separated precisely into wages, interest, rent and profit. It is therefore recorded as mixed income under the income method.

Interest is the return paid for the use or lending of financial or physical capital in production. In the income method, factor payments are classified according to the factor that earns them: wages reward labour, rent rewards land, interest rewards capital and profit rewards entrepreneurship. Hence the correct answer is interest.

Factor incomes are payments earned by supplying the factors of production. Wages are earned by labour, rent by land or property, interest by capital, and profit by entrepreneurship. The other alternatives contain transfers, financial transactions, taxes or expenditure components, so they are not a set of factor incomes.

The income method estimates national income by adding the factor incomes generated during the production of goods and services. These include compensation of employees, rent, interest, profit and mixed income, subject to the relevant national-income adjustments. Adding final expenditure belongs to the expenditure method, not the income method.

Voluntary unpaid services generally do not involve a market transaction or an observable payment. Since national income is measured in monetary terms, assigning a reliable and non-arbitrary value to such work is difficult. Consequently, it is normally excluded from the income method, even though the service may have real social and economic value.

Leave salary is paid because of an employment relationship and forms part of the employee’s remuneration or employment benefits. It is therefore included in compensation of employees when measuring factor income. It is not mixed income, because the recipient is not combining self-employment returns, and it is unrelated to exports or transfer payments.

Prize money is included as factor income only when it is a return for a productive service, performance, employment, or other economic contribution. A lottery prize, gift, donation, or windfall received without providing a factor service is a transfer receipt and is excluded from factor income in the income method. Therefore, option A is correct.

Net profit is the reward received by an entrepreneur for organising production, making business decisions, bearing uncertainty, and assuming risk. In the income method, it is classified as entrepreneurial income or profit. Wages reward labour, rent rewards land, and interest rewards the use of capital, so option A is unambiguous.
