Show answer & explanation

Answer

State pensions and unemployment relief grants match with Transfer payment (Excluded from National Income); Dividends distributed to shareholders match with Corporate profit component; Net income earned by a sole proprietor matches with Mixed income of the self-employed; Royalties received by a landowner match with Rental income.

The income method measures national income by summing all factor rewards earned by residents for participating in current economic production: compensation of employees (wages/salaries), rental income (including land royalties), net interest, corporate profits (dividends, retained earnings, tax), and mixed income of the self-employed. Receipts that do not correspond to productive output, such as welfare grants and pensions, are transfer payments and are strictly excluded.

Step-by-Step Solution

1

Identify non-factor payments that do not reflect current economic output.

Unemployment grants and state pensions are non-factor receipts (transfer payments) and must be excluded from Gross Domestic Product under the income approach.

Including transfer payments leads to double counting, as no productive activity occurred in exchange for the payment during the current accounting period.

2

Classify earnings from corporate enterprise ownership.

Dividends paid out of corporate profits are factor payments accruing to shareholders for providing entrepreneurial risk capital.

Corporate profits consist of dividends, corporate taxes, and undistributed profits, all of which are included under factor incomes.

3

Determine the classification of self-employed earnings.

Income of an independent sole proprietor is classified as mixed income of the self-employed.

Unincorporated business owners blend wage income, interest, rent, and profit into a single unseparated income pool.

4

Classify earnings derived from natural resources and property rights.

Royalties paid for mineral extraction rights on land are grouped under rental income.

Rent includes payments for the use of land and natural resources in production.

The table below shows national income components for a hypothetical economy in a given financial year:

Income Component	Amount ($ millions)
Wages and Salaries	150
Corporate Profits	45
Rental Income	25
Net Interest	20
Government Transfer Payments	15
Net Factor Income from Abroad	-10

Using the income method of national income accounting, what is the Gross National Product (GNP) at factor cost?

$230 million

$240 million

$245 million

$255 million

Show answer & explanation

Answer: $230 million

Answer

$230 million

Under the income approach, national income at factor cost includes only payments made to factors of production: wages (

150 million), profits (

45 million), rental income (

25 million), and net interest (

20 million), totaling

240 million for domestic earnings. Transfer payments (

15 million) are excluded as non-factor receipts. Adjusting for Net Factor Income from Abroad (-

10 million) yields the correct Gross National Product of

230 million.

Step-by-Step Solution

1

Calculate Gross Domestic Income (GDI) at factor cost by summing rewards earned by factors of production.

GDI at factor cost = Wages (

150m) + Profits (

45m) + Rent (

25m) + Interest (

20m) = $240 million.

Government transfer payments ($15 million) are excluded because they are unearned receipts that do not represent current productive services.

2

Convert GDI at factor cost to Gross National Product (GNP) at factor cost by adjusting for Net Factor Income from Abroad (NFIA).

GNP at factor cost = GDI (

240m) + NFIA (-

10m) = $230 million.

GNP accounts for total income earned by national residents regardless of location, requiring the inclusion of net factor income from abroad.

Question 3Question →

When estimating a country's national income using the income method, which of the following receipts must be excluded because it does not represent payment for factor services rendered?

Unemployment benefits paid by the government

Wages and salaries earned by factory employees

Net rental income received by property owners

Corporate profits retained by public companies

Show answer & explanation

Answer: Unemployment benefits paid by the government

Answer

Unemployment benefits paid by the government must be excluded when estimating national income using the income method.

Under the income method of national income accounting, only factor incomes earned through contribution to current economic production (wages, rent, interest, and profit) are included. Unemployment benefits are transfer payments made by government to individuals without any corresponding exchange of goods or factor services. Thus, they must be excluded to prevent overstating national income.

Step-by-Step Solution

1

Identify the basic principle of the income method of national income measurement.

The income method sums all earned factor rewards (wages, rent, interest, and profits) paid to factors of production for contributing to current productive activity.

National income measures only the value of economic production generated within a given period.

2

Evaluate each transaction to distinguish between factor incomes and transfer payments.

Wages, rent, and profits are payments for factor services rendered. Transfer payments, such as unemployment benefits, pensions, or student grants, are gifts or relief payments involving no current exchange of goods or services.

Including transfer payments would result in double counting income that was already earned and taxed elsewhere.

3

Select the item that must be excluded.

Unemployment benefits paid by the government must be excluded.

It represents a unearned transfer of income rather than factor earnings from current production.

Question 4Question →

A developing economy recorded the following national income statistics for a given fiscal year:

Economic Component	Amount ($ millions)
Compensation of employees	$520$
Net operating surplus	$280$
Mixed income of the self-employed	$150$
Social security transfer payments	$60$
Consumption of fixed capital (Depreciation)	$40$
Net Factor Income from Abroad (NFIA)	$-25$

Based on the income method of measurement, what is the country's Gross National Product at factor cost ( $GNP_{FC}$ )?

$925 million

$965 million

$1,015 million

$1,025 million

Show answer & explanation

Answer: $965 million

Answer

$965 million

Under the income method, total factor earnings comprise compensation of employees (

520 million), net operating surplus (

280 million), and mixed income of the self-employed (

150 million), giving Net Domestic Product at factor cost (

NDP_{FC}

) of

950 million. Adding depreciation (

40 million) converts this to

GDP_{FC}

(

990 million). Finally, adjusting for Net Factor Income from Abroad (

-25 million) yields

GNP_{FC} = 990 + (-25) = \

965 million

. Social security transfer payments ($60 million) are omitted as non-factor receipts.

Step-by-Step Solution

1

Exclude non-factor receipts and sum factor incomes to calculate Net Domestic Product at factor cost (

NDP_{FC}

).

NDP_{FC} = 520 + 280 + 150 = 950\text{ million}

. Transfer payments ($60 million) are excluded.

Transfer payments are unilateral payments received without providing productive factors/goods in return.

2

Add consumption of fixed capital (depreciation) to convert

NDP_{FC}

to Gross Domestic Product at factor cost (

GDP_{FC}

).

GDP_{FC} = 950 + 40 = 990\text{ million}

.

Gross aggregates include capital consumption allowance (depreciation), whereas net aggregates exclude it.

3

Add Net Factor Income from Abroad (NFIA) to

GDP_{FC}

to arrive at Gross National Product at factor cost (

GNP_{FC}

).

GNP_{FC} = 990 + (-25) = 965\text{ million}

.

GNP measures total income earned by residents regardless of location (

GNP = GDP + NFIA

).

Match each economic receipt under the income method of measuring national income with its appropriate factor income classification or accounting treatment.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Wages and salaries paid to factory employees matches Compensation of employees; Rental income earned by property owners matches Operating surplus (Rent); Interest received on productive capital investments matches Operating surplus (Net interest); Old-age pensions paid by the government matches Transfer payment (Excluded from national income).

Under the income method, national income is measured by adding up all factor incomes (compensation of employees, rent, interest, profit, and self-employment income) earned by factors of production, while excluding transfer payments like pensions which are unearned receipts.

Step-by-Step Solution

1

Distinguish between factor income (payments for productive services) and transfer payments (unearned receipts).

Wages, rent, and interest are productive factor incomes, while pensions are non-factor transfer receipts.

The income method only sums earnings generated from the current production of goods and services.

2

Classify each factor income into its designated income category.

Labor returns are Compensation of Employees; land and capital returns belong under Operating Surplus; government relief/pensions are Excluded Transfer Payments.

This alignment reflects standard national income accounting framework rules.

An economy recorded the following national income components for a given fiscal year:

Component	Amount (₦ million)
Wages and salaries	$450$
Rent on property	$120$
Net interest	$80$
Corporate profits	$200$
Transfer payments (Social pensions)	$50$

Using the income method of measuring national income, what is the Gross Domestic Product at factor cost (in ₦ million)?

Show answer & explanation

Answer: 850

Answer

The Gross Domestic Product at factor cost using the income method is 850 million Naira.

Under the income method of national income accounting, GDP at factor cost is calculated by summing all rewards accruing to the factors of production: Wages and salaries (labour) + Rent (land) + Interest (capital) + Profits (entrepreneurship). Transfer payments such as social pensions are unearned receipts and must be omitted. Thus, National Income = ₦450m + ₦120m + ₦80m + ₦200m = ₦850m.

Step-by-Step Solution

1

Identify valid factor incomes under the income approach

Earned incomes are Wages (

450

million), Rent (

120

million), Interest (

80

million), and Profits (

200

million).

The income method aggregates rewards paid to factors of production (land, labour, capital, and enterprise) for producing current goods and services.

2

Exclude transfer payments from calculation

Transfer payments (

50

million) are excluded.

Transfer payments are receipts for which no corresponding productive service is rendered in the current period, so including them would cause double counting.

3

Calculate total GDP at factor cost

450 + 120 + 80 + 200 = 850

million Naira.

Summing all constituent factor income components yields the total national income at factor cost.

Based on the information provided above, calculate the Net National Product at factor cost ( $NNP_{FC}$ ) in millions of dollars.

Show answer & explanation

Answer: 850

Answer

The Net National Product at factor cost (

NNP_{FC}

) is $850 million.

The Income Method sums all factor payments earned by owners of factors of production for providing current productive services. Combining compensation of employees (

460M), rental income (

75M), net business interest (

60M), total corporate profits (

160M), and mixed income of self-employed (

115M) yields Net Domestic Product at factor cost (

NDP_{FC} = \

870\text{ million}

). Adding Net Factor Income from Abroad (

NFIA = \$45\text{M} - \$65\text{M} = -\$20\text{ million}

) yields Net National Product at factor cost (

NNP_{FC} = \$850\text{ million}

). Non-factor receipts (transfer payments, public debt interest, capital gains) and depreciation are excluded.

Step-by-Step Solution

1

Calculate Compensation of Employees

$460 million

Compensation of employees includes both direct wages/salaries (

420M) and non-wage benefits such as employers' social security contributions (

40M).

2

Calculate Total Corporate Profits

$160 million

Total corporate profits equal the sum of distributed profits (dividends of

90M), corporate profit taxes (

40M), and retained earnings (undistributed profits of $30M).

3

Calculate Net Domestic Product at factor cost (

NDP_{FC}

)

$870 million

NDP_{FC}

is the sum of factor earnings within the domestic economy: Compensation of Employees (

460M) + Rent (

75M) + Net business interest (

60M) + Corporate profits (

160M) + Mixed income of self-employed ($115M). Non-factor payments (transfer payments, public debt interest, capital gains) are strictly excluded.

4

Determine Net Factor Income from Abroad (

NFIA

)

-$20 million

NFIA

is calculated as factor income received from abroad (

45M) minus factor income paid to foreigners abroad (

65M).

5

Calculate Net National Product at factor cost (

NNP_{FC}

)

$850 million

NNP_{FC} = NDP_{FC} + NFIA = 870 + (-20) = 850

. Depreciation is not added because the target aggregate is Net, and indirect taxes/subsidies are not added/subtracted because the evaluation is at factor cost.

An economic statistician evaluating a nation's performance via the income approach compiles the following components for a given year:

- Compensation of employees: $\text{\mathbb{N}}380\text{ million}$
- Operating surplus (rent, interest, and profit): $\text{\mathbb{N}}210\text{ million}$
- Mixed income of self-employed individuals: $\text{\mathbb{N}}90\text{ million}$
- Net factor income from abroad (NFIA): $\text{\mathbb{N}}-15\text{ million}$

₦720 million

₦665 million

₦705 million

Show answer & explanation

Answer: ₦680 million

Answer

The Gross Domestic Product at factor cost using the income method is ₦680 million.

Under the income method of measuring national income, Gross Domestic Product at factor cost (

\text{GDP}_{fc}

) equals the sum of all factor rewards earned within the domestic boundary: Compensation of Employees + Operating Surplus + Mixed Income of Self-Employed. Evaluating the given figures gives

\text{\mathbb{N}}380\text{ million} + \text{\mathbb{N}}210\text{ million} + \text{\mathbb{N}}90\text{ million} = \text{\mathbb{N}}680\text{ million}

. Transfer payments are excluded because they are unearned receipts, and NFIA is omitted because the question specifies GDP rather than GNP.

Step-by-Step Solution

1

Identify the factor income components that contribute to domestic income generation.

Factor incomes include Compensation of employees (₦380m), Operating surplus (₦210m), and Mixed income of self-employed (₦90m).

The income method measures GDP at factor cost by aggregating all earned factor rewards generated within the domestic territory.

2

Filter out non-factor receipts such as transfer payments.

Transfer payments (₦40m) are excluded.

Transfer payments are unearned income transactions without corresponding production of goods or services.

3

Sum the factor income components to find GDP at factor cost.

\text{GDP}_{fc} = 380 + 210 + 90 = \text{\mathbb{N}}680\text{ million}

.

NFIA (-₦15m) is used to convert GDP to GNP, so it must not be included when solving specifically for GDP.

Match each national income component under the income method of measurement with its correct definition or accounting scope.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Compensation of Employees corresponds to total gross rewards paid to workers. Operating Surplus corresponds to property and entrepreneurial income (profits, rent, interest). Mixed Income of Self-Employed corresponds to the combined unseparated earnings of sole proprietors. Net Factor Income from Abroad corresponds to net income flows earned from abroad versus paid to foreigners.

Under the income method of measuring national income, total national output is measured by summing all rewards paid to the factors of production: Compensation of Employees (labor reward), Operating Surplus (capital and land returns to incorporated firms), Mixed Income (unseparated returns for self-employed individuals), and Net Factor Income from Abroad (external net income balance). Each concept precisely matches its respective functional component in national income accounting.

Step-by-Step Solution

1

Identify factor payments to labor

Match Compensation of Employees with gross worker rewards (wages, salaries, social contributions).

Labor receives compensation as its direct reward under the income approach.

2

Identify corporate property and business earnings

Match Operating Surplus with profits, rent, and interest earned by incorporated enterprises.

Operating surplus accumulates capital and property earnings in national accounts.

3

Identify informal and sole proprietor earnings

Match Mixed Income of Self-Employed with combined earnings where labor and capital returns cannot be split.

Unincorporated businesses generate income that merges personal effort with capital investment.

4

Identify international income adjustments

Match Net Factor Income from Abroad with net factor payments received from abroad minus payments sent abroad.

Net factor income from abroad reconciles GDP measured domestically with GNP.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Old-age pensions match with exclusion as a transfer payment; Undistributed corporate profits match with inclusion as corporate profit; Mineral royalties match with inclusion as rent/property income; Dividends paid to foreign investors match with deduction from GDP to arrive at GNP via Net Factor Income from Abroad.

Under the income method of national income measurement, total national income is computed by summing all factor rewards (wages, rent, interest, profit) earned by residents for productive services rendered during the year. Transfer payments like old-age pensions are excluded because no productive service was rendered. Retained corporate profits form an integral part of earned corporate profits. Royalties paid for land or mineral rights are treated as rent. Income accruing to foreign residents (dividends paid abroad) must be deducted from GDP to derive GNP.

Step-by-Step Solution

1

Identify unearned receipts (transfer payments) vs earned factor payments

Pensions represent transfer payments and are excluded from national income.

National income accounting counts only income earned from contributing to current production.

2

Classify domestic factor earnings into basic factor reward categories (Wages, Rent, Interest, Profit)

Retained earnings belong to corporate profit, and mineral royalties belong to land rent.

Income method sums rewards to factors of production: land earns rent, capital earns profit.

3

Apply Net Factor Income from Abroad (NFIA) adjustments to separate domestic output (GDP) from national output (GNP)

Dividends paid to foreign shareholders represent income outflow abroad and must be subtracted when calculating GNP.

GNP measures income earned by national residents regardless of geographic location.

Question 11Question →

The following financial statistics were extracted from the national income accounts of an economy for a given fiscal year:

Component	Amount (₦ million)
Compensation of employees	410
Rent on property	95
Net interest income	70
Undistributed corporate profits and dividends	135
Mixed income of self-employed individuals	110
Old-age pension payments	50
Consumption of fixed capital	40
Net factor income from abroad	30

Using the income method, calculate the Gross Domestic Product ( $GDP$ ) at factor cost in ₦ million.

Show answer & explanation

Answer: 820

Answer

The Gross Domestic Product (

GDP

) at factor cost calculated using the income method is 820 ₦ million.

Under the income approach, Gross Domestic Product (

GDP

) at factor cost is derived by summing all domestic factor rewards: Compensation of employees (

₦410

m) + Rent (

₦95

m) + Net interest (

₦70

m) + Corporate profits (

₦135

m) + Mixed income (

₦110

m) =

₦820

million. Old-age pensions are excluded because transfer payments do not represent payment for current economic output. Consumption of fixed capital is not subtracted when computing Gross output, and Net factor income from abroad is excluded because the measure requested is domestic, not national.

Step-by-Step Solution

1

Identify and select factor income components earned from domestic production.

Factor incomes = Compensation of employees (

₦410

m), Rent (

₦95

m), Net interest (

₦70

m), Corporate profits (

₦135

m), and Mixed income (

₦110

m).

The income method sums all factor rewards earned by domestic owners of factors of production.

2

Filter out non-factor payments, depreciation, and foreign factor receipts.

Excluded items: Old-age pension payments (

₦50

m), Consumption of fixed capital (

₦40

m), and Net factor income from abroad (

₦30

m).

Transfer payments do not reflect current output; depreciation is not deducted for Gross income; and NFIA converts domestic aggregate to national aggregate.

3

Calculate total Gross Domestic Product at factor cost (

GDP_{FC}

).

GDP_{FC} = 410 + 95 + 70 + 135 + 110 = 820

million Naira.

Adding all earned domestic factor incomes yields total GDP at factor cost.
