Question 21Question

An economist is comparing the standard of living between Country X, a developing nation with a large non-monetized subsistence agriculture sector, and Country Y, an industrialized nation with a fully monetized economy. Which of the following best explains why using per capita national income figures alone will distort the comparison of living standards between the two countries?

Show answer & explanation

Answer: Unrecorded non-monetized production in Country X leads to an underestimation of its total economic output and welfare.

Answer

Unrecorded non-monetized production in Country X leads to an underestimation of its total economic output and welfare.
National income estimates rely primarily on market transactions measured in monetary terms. In developing economies with large subsistence sectors, significant amounts of goods are produced and consumed without entering the market system. Consequently, national income statistics undercount total production and underestimate actual living standards, making direct comparisons with fully monetized economies inaccurate.

Step-by-Step Solution

1
Identify the primary structural difference between the two economies
Country X has a significant subsistence (non-monetized) sector, whereas Country Y has a monetized market economy.
National income accounting relies on monetary transactions recorded through formal markets.
2
Analyze how non-monetized transactions affect national income statistics
Goods produced and consumed at home (such as subsistence crops or self-provided services) are omitted from official national income figures.
Statistical agencies struggle to evaluate or capture unmarketed output accurately.
3
Evaluate the impact on cross-country living standard comparisons
Country X's reported per capita income is lower than its true economic output, understating the actual welfare of its population compared to Country Y.
The omission of subsistence production distorts the comparative metric.

Question 22Question

In many developing nations, a substantial portion of agricultural output is consumed directly by the farmers and their families rather than sold in the market. Why does this non-marketed production pose a major obstacle in national income accounting?

Show answer & explanation

Answer: The lack of market price data makes it difficult to assign an accurate monetary value to subsistence output.

Answer

The lack of market price data makes it difficult to assign an accurate monetary value to subsistence output.
National income accounting depends on recorded financial transactions. When goods are produced for direct household consumption, no commercial exchange occurs, making it extremely difficult for statisticians to accurately impute market values.

Step-by-Step Solution

1
Identify the nature of subsistence production.
Subsistence production consists of real goods produced and consumed by households without passing through commercial markets.
National income accounting relies primarily on documented market transactions and price mechanisms.
2
Analyze the core measurement difficulty.
Without market receipts or uniform price tags, imputing (estimating) the monetary value of self-consumed output is imprecise and often under-recorded.
Excluding non-monetized sectors leads to an underestimation of total national output.

Question 23Question

In Year 1, an economy recorded a Nominal GDP of ₦800 billion with a base price index of 100. By Year 2, the Nominal GDP grew to ₦1,200 billion, the price index rose to 150, and the total population reached 50 million. What is the Real Per Capita Income of the economy in Year 2?

Show answer & explanation

Answer: ₦16,000

Answer

₦16,000
To find the Real Per Capita Income, Nominal GDP must first be adjusted for inflation using the Price Index: Real GDP=(Nominal GDPPrice Index)×100=(1,200150)×100=₦800 billion\text{Real GDP} = (\frac{\text{Nominal GDP}}{\text{Price Index}}) \times 100 = (\frac{1,200}{150}) \times 100 = \text{₦800 billion}. Dividing this Real GDP by the Year 2 population of 50 million yields ₦800,000,000,00050,000,000=₦16,000\frac{\text{₦800,000,000,000}}{50,000,000} = \text{₦16,000}.

Step-by-Step Solution

1
Calculate Real GDP for Year 2
Real GDP = (Nominal GDP / Price Index) × 100 = (₦1,200 billion / 150) × 100 = ₦800 billion
Nominal GDP includes price inflation; dividing by the price index eliminates inflation to show true output volume.
2
Calculate Real Per Capita Income for Year 2
Real Per Capita Income = Real GDP / Population = ₦800,000,000,000 / 50,000,000 = ₦16,000
Per capita real income measures the real output available per individual in the population.

Match each national economic transaction with its correct flow classification within the open four-sector circular flow of income model.

Click a left item, then click its matching right item

Items

Direct taxation levied on household disposable income
Business expenditures on physical capital goods and machinery
Household purchases of imported consumer goods and services
Foreign country payments for domestic export commodities

Matches

Show answer & explanation

Answer

Direct taxation levied on household income matches Domestic Leakage (Withdrawal) to the Public Sector; Business expenditures on capital goods match Domestic Injection into the Productive Sector; Household purchases of imported goods match Foreign Leakage (Withdrawal) from the Circular Flow; Foreign country payments for domestic exports match Foreign Injection into the Circular Flow.
In national income accounting, leakages (or withdrawals) are income streams not spent on domestic consumer goods and services (S+T+MS + T + M). Direct taxation (TT) diverts income to the government sector, and imports (MM) send purchasing power to overseas markets. Conversely, injections (I+G+XI + G + X) add autonomous demand to domestic firms; investment spending (II) funds capital goods, and export revenues (XX) reflect foreign expenditure on domestic products.

Step-by-Step Solution

1
Identify the four-sector circular flow components
The components are Households, Firms, Government, and the Rest of the World, giving leakages (S, T, M) and injections (I, G, X).
Establishing the functional distinction between money entering (injections) and leaving (leakages) the circular income stream.
2
Classify domestic transactions
Taxes (T) reduce household consumption spending (Leakage to public sector), while investment (I) expands production capacity (Domestic injection).
Taxes divert funds out of the basic household-firm loop, whereas investment adds autonomous funds to firms.
3
Classify international transactions
Imports (M) transfer income abroad (Foreign leakage), while export revenue (X) brings external income into domestic production (Foreign injection).
Import expenditure escapes the domestic flow, whereas export sales pump foreign revenue into domestic industries.

Question 25Question

In a given financial year, an economy records a Net National Product (NNP\text{NNP}) of N6,200 million\text{N}6,200\text{ million} and a Capital Consumption Allowance (Depreciation) of N450 million\text{N}450\text{ million}. The factor income earned by domestic citizens from abroad is N320 million\text{N}320\text{ million}, while the factor income paid to foreign residents within the economy is N510 million\text{N}510\text{ million}. What is the value of the Gross Domestic Product (GDP\text{GDP}) of this economy in million Naira?

Show answer & explanation

Answer: 6840

Answer

6840 million Naira
To calculate Gross Domestic Product (GDP), first derive Gross National Product (GNP) by adding Capital Consumption Allowance (Depreciation) to Net National Product (NNP): GNP=6,200+450=6,650 million Naira\text{GNP} = 6,200 + 450 = 6,650\text{ million Naira}. Next, compute Net Factor Income from Abroad (NFIA) as factor income received from abroad minus factor income paid to foreigners: NFIA=320510=190 million Naira\text{NFIA} = 320 - 510 = -190\text{ million Naira}. Finally, apply the national accounting identity GNP=GDP+NFIA\text{GNP} = \text{GDP} + \text{NFIA}, rearranged as GDP=GNPNFIA=6,650(190)=6,840 million Naira\text{GDP} = \text{GNP} - \text{NFIA} = 6,650 - (-190) = 6,840\text{ million Naira}.

Step-by-Step Solution

1
Calculate Gross National Product (GNP) from Net National Product (NNP) and Depreciation
GNP = 6,200 + 450 = 6,650 million Naira
Gross aggregates include depreciation, whereas net aggregates exclude it: GNP=NNP+Depreciation\text{GNP} = \text{NNP} + \text{Depreciation}.
2
Determine Net Factor Income from Abroad (NFIA)
NFIA = 320 - 510 = -190 million Naira
NFIA is defined as factor income earned from abroad by citizens minus factor income paid to foreign residents domestically.
3
Determine Gross Domestic Product (GDP) using GNP and NFIA
GDP = 6,650 - (-190) = 6,840 million Naira
Because GNP=GDP+NFIA\text{GNP} = \text{GDP} + \text{NFIA}, rearranging gives GDP=GNPNFIA\text{GDP} = \text{GNP} - \text{NFIA}. Subtracting a negative value is equivalent to adding its positive magnitude.

Question 26Question

In a given fiscal year, a nation records a Gross Domestic Product (GDP) of $900 billion\$900\text{ billion} and a capital consumption allowance (depreciation) of $60 billion\$60\text{ billion}. What is the value of the country's Net Domestic Product (NDP)?

Show answer & explanation

Answer: $840 billion\$840\text{ billion}

Answer

The Net Domestic Product (NDP) of the country is $840 billion\$840\text{ billion}.
Net Domestic Product (NDP) measures the net market value of all final goods and services produced within a country's boundaries. It is calculated by subtracting Capital Consumption Allowance (depreciation) from Gross Domestic Product (GDP): NDP=GDPDepreciation=$900 billion$60 billion=$840 billion\text{NDP} = \text{GDP} - \text{Depreciation} = \$900\text{ billion} - \$60\text{ billion} = \$840\text{ billion}.

Step-by-Step Solution

1
Identify the relationship between Gross Domestic Product (GDP), depreciation, and Net Domestic Product (NDP)
NDP=GDPDepreciation\text{NDP} = \text{GDP} - \text{Depreciation}
Net aggregates account for the wear and tear of capital goods used during production.
2
Substitute the given numeric values into the national income accounting identity
NDP=$900 billion$60 billion=$840 billion\text{NDP} = \$900\text{ billion} - \$60\text{ billion} = \$840\text{ billion}
Subtracting $60 billion\$60\text{ billion} from $900 billion\$900\text{ billion} yields the net value of domestic output.

Question 27Question

During a regional economic review, statistical data indicates that Region A experienced an 8% growth in Real Per Capita Income following rapid industrialization, whereas Region B recorded zero growth. However, a comprehensive social assessment reveals that residents of Region B enjoy superior health outcomes, lower pollution levels, and higher overall life satisfaction. Which of the following accounts for this apparent contradiction between national income data and true economic welfare?

Show answer & explanation

Answer: National income data excludes negative externalities such as environmental pollution and fails to capture non-monetized welfare factors.

Answer

National income data excludes negative externalities such as environmental pollution and fails to capture non-monetized welfare factors.
National income estimates measure economic activity in monetary terms but suffer from major limitations when used to assess standard of living. Rapid industrialization increases output (raising Real Per Capita Income), but it often creates unpriced negative externalities such as environmental pollution, urban congestion, and health risks. Because national income accounting ignores these social costs as well as non-marketed quality-of-life factors, a region with lower income growth can enjoy a superior overall standard of living.

Step-by-Step Solution

1
Analyze the contradiction presented in the stem.
Region A shows higher quantitative Real Per Capita Income growth, yet Region B shows higher qualitative welfare indicators (health, clean environment, life satisfaction).
National income accounts focus on the market value of final goods and services produced.
2
Evaluate the conceptual limitations of national income estimates as a measure of standard of living.
Industrial expansion often generates unpriced negative externalities (e.g., air and water pollution, health degradation) that reduce actual quality of life without reducing GDP.
National income measures monetary output rather than social welfare or environmental quality.
3
Identify the correct limitation explaining why Region B exhibits higher welfare despite lower income growth.
The exclusion of negative externalities and non-market welfare considerations from GDP figures explains why higher income does not guarantee superior living standards.
Living standards depend on both monetary income and qualitative factors such as health, clean air, and non-priced amenities.

Question 28Question

The following national income figures are recorded for an economy in a given year:

- Gross Domestic Product at market prices (GDPmpGDP_{mp}): $1,420\$1,420 billion
- Factor income received by domestic residents from abroad: $95\$95 billion
- Factor income paid to foreign residents within the domestic economy: $140\$140 billion
- Capital Consumption Allowance (Depreciation): $105\$105 billion
- Indirect taxes: $115\$115 billion
- Subsidies: $30\$30 billion

What is the Net National Product at factor cost (NNPfcNNP_{fc}) of this economy in billions of dollars?

Show answer & explanation

Answer: 1185

Answer

The Net National Product at factor cost (NNPfcNNP_{fc}) is $1,185 billion.
To derive Net National Product at factor cost (NNPfcNNP_{fc}), start with GDPmp=1,420GDP_{mp} = 1,420. Calculate Net Factor Income from Abroad (NFIANFIA) as 95140=4595 - 140 = -45 billion dollars, giving GNPmp=1,420+(45)=1,375GNP_{mp} = 1,420 + (-45) = 1,375 billion dollars. Subtracting depreciation (105105 billion dollars) yields NNPmp=1,270NNP_{mp} = 1,270 billion dollars. Finally, subtracting Net Indirect Taxes (11530=85115 - 30 = 85 billion dollars) converts market price to factor cost: 1,27085=1,1851,270 - 85 = 1,185 billion dollars.

Step-by-Step Solution

1
Determine Net Factor Income from Abroad (NFIA)
NFIA = 95 billion95\text{ billion} - 140\text{ billion} = -\45 billion45\text{ billion}
NFIA measures the net flow of factor earnings between domestic residents and the rest of the world.
2
Convert GDP at market prices to GNP at market prices
GNP_{mp} = 1,420 billion+($45 billion)=$1,375 billion1,420\text{ billion} + (-\$45\text{ billion}) = \$1,375\text{ billion}
Adding NFIA to domestic product converts gross domestic output to gross national output.
3
Deduct depreciation to obtain NNP at market prices
NNP_{mp} = 1,375 billion$105 billion=$1,270 billion1,375\text{ billion} - \$105\text{ billion} = \$1,270\text{ billion}
Subtracting capital consumption allowance converts gross national measures to net national measures.
4
Calculate Net Indirect Taxes (NIT)
NIT = 115 billion$30 billion=$85 billion115\text{ billion} - \$30\text{ billion} = \$85\text{ billion}
Net indirect taxes equal total indirect taxes minus subsidies provided by government.
5
Adjust NNP at market prices to factor cost
NNP_{fc} = 1,270 billion$85 billion=$1,185 billion1,270\text{ billion} - \$85\text{ billion} = \$1,185\text{ billion}
Converting from market price evaluation to factor cost requires subtracting indirect taxes and adding back subsidies.

Question 33Question

An economy records a total Personal Income of ₦720 million\text{₦720 million} in a given fiscal year. Within the same period, household personal direct taxes total ₦110 million\text{₦110 million}, government transfer payments are ₦45 million\text{₦45 million}, and social security contributions amount to ₦30 million\text{₦30 million}. What is the Disposable Income of households in this economy?

Show answer & explanation

Answer: ₦610 million\text{₦610 million}

Answer

The Disposable Income of households in the economy is ₦610 million\text{₦610 million}.
Disposable Income (DIDI) is the portion of Personal Income (PIPI) that individuals have available for spending and saving. It is calculated strictly by subtracting personal direct taxes from Personal Income: DI=PIPersonal Direct Taxes=₦720 million₦110 million=₦610 millionDI = PI - \text{Personal Direct Taxes} = \text{₦720 million} - \text{₦110 million} = \text{₦610 million}. Additional items such as transfer payments and social security contributions are already reflected in the Personal Income aggregate and should not be adjusted for a second time.

Step-by-Step Solution

1
Identify the relevant formula for Disposable Income (DI)
Disposable Income (DI)=Personal Income (PI)Personal Direct Taxes\text{Disposable Income (DI)} = \text{Personal Income (PI)} - \text{Personal Direct Taxes}
Disposable Income represents the amount of income households have remaining after paying all mandatory direct taxes to the government.
2
Identify the values provided in the problem and filter out redundant components
PI=₦720 million\text{PI} = \text{₦720 million}, Personal Direct Taxes=₦110 million\text{Personal Direct Taxes} = \text{₦110 million}. Transfer payments (₦45 million\text{₦45 million}) and social security contributions (₦30 million\text{₦30 million}) are ignored.
Personal Income already includes transfer payments and excludes social security contributions. Any additional addition or subtraction of these items when deriving Disposable Income from Personal Income constitutes double counting.
3
Calculate Disposable Income
DI=720110=₦610 million\text{DI} = 720 - 110 = \text{₦610 million}
Subtracting personal direct taxes directly yields the final disposable household income.

Question 35Question

A cotton farmer sells raw cotton to a textile mill for ₦50,000. The textile mill processes the cotton into fabric and sells it to a garment factory for ₦120,000. The garment factory turns the fabric into shirts and sells them to final consumers for ₦200,000. What is the total contribution of this production process to National Income using the output (value-added) method?

Show answer & explanation

Answer: ₦200,000

Answer

The total contribution to National Income is ₦200,000.
The output method avoids double counting by summing only the incremental net value created at each production stage (₦50,000 + ₦70,000 + ₦80,000 = ₦200,000), which also equals the final market value of the consumer goods.

Step-by-Step Solution

Question 36Question

A central bank's statistical bulletin highlights that a country recorded a Gross National Product (GNP\text{GNP}) of N9,500 million\text{N}9,500\text{ million}, a Net Domestic Product (NDP\text{NDP}) of N8,100 million\text{N}8,100\text{ million}, and a Capital Consumption Allowance (depreciation) of N600 million\text{N}600\text{ million} in a given fiscal year. What is the value of the Net Factor Income from Abroad (NFIA\text{NFIA})?

Show answer & explanation

Answer: N800 million\text{N}800\text{ million}

Answer

N800 million\text{N}800\text{ million}
To find Net Factor Income from Abroad (NFIA\text{NFIA}), we use the core identities of national income accounting. First, Gross Domestic Product (GDP\text{GDP}) is derived by adding depreciation (Capital Consumption Allowance) to Net Domestic Product (NDP\text{NDP}): GDP=N8,100 million+N600 million=N8,700 million\text{GDP} = \text{N}8,100\text{ million} + \text{N}600\text{ million} = \text{N}8,700\text{ million}. Next, Gross National Product (GNP\text{GNP}) is related to GDP\text{GDP} by the formula GNP=GDP+NFIA\text{GNP} = \text{GDP} + \text{NFIA}. Rearranging for NFIA\text{NFIA} gives NFIA=GNPGDP=N9,500 millionN8,700 million=N800 million\text{NFIA} = \text{GNP} - \text{GDP} = \text{N}9,500\text{ million} - \text{N}8,700\text{ million} = \text{N}800\text{ million}.

Step-by-Step Solution

1
Calculate Gross Domestic Product (GDP\text{GDP}) from Net Domestic Product (NDP\text{NDP}) and Capital Consumption Allowance.
GDP=NDP+Depreciation=N8,100 million+N600 million=N8,700 million\text{GDP} = \text{NDP} + \text{Depreciation} = \text{N}8,100\text{ million} + \text{N}600\text{ million} = \text{N}8,700\text{ million}
Gross aggregates include depreciation, while net aggregates exclude depreciation.
2
Calculate Net Factor Income from Abroad (NFIA\text{NFIA}) using the identity relating GNP\text{GNP} and GDP\text{GDP}.
NFIA=GNPGDP=N9,500 millionN8,700 million=N800 million\text{NFIA} = \text{GNP} - \text{GDP} = \text{N}9,500\text{ million} - \text{N}8,700\text{ million} = \text{N}800\text{ million}
GNP\text{GNP} is equal to GDP\text{GDP} plus Net Factor Income from Abroad.

Question 37Question

Match each stage of production in the palm oil supply chain with its correct net Value Added contribution to National Income based on the transaction values provided.

Click a left item, then click its matching right item

Items

Oil palm farming (Harvested fruits sold for ₦10,000)
Oil milling (Crude palm oil sold for ₦30,000)
Refining (Bottled cooking oil sold for ₦65,000)
Retailing (Final sale to household consumers for ₦80,000)

Matches

Show answer & explanation

Answer

Oil palm farming matches Value added of ₦10,000; Oil milling matches Value added of ₦20,000; Refining matches Value added of ₦35,000; Retailing matches Value added of ₦15,000.
Under the value-added approach, the contribution of each stage to GDP is calculated as Output Value minus Intermediate Consumption. For farming: ₦10,000 - ₦0 = ₦10,000. For milling: ₦30,000 - ₦10,000 = ₦20,000. For refining: ₦65,000 - ₦30,000 = ₦35,000. For retailing: ₦80,000 - ₦65,000 = ₦15,000.

Step-by-Step Solution

1
Calculate Value Added for Stage 1 (Farming)
₦10,000 - ₦0 = ₦10,000
Value added equals total output value minus intermediate input costs.
2
Calculate Value Added for Stage 2 (Milling)
₦30,000 - ₦10,000 = ₦20,000
Subtract the cost of intermediate input (raw fruit at ₦10,000) from output value (crude oil at ₦30,000).
3
Calculate Value Added for Stage 3 (Refining)
₦65,000 - ₦30,000 = ₦35,000
Subtract the cost of crude oil (₦30,000) from the refined oil output value (₦65,000).
4
Calculate Value Added for Stage 4 (Retailing)
₦80,000 - ₦65,000 = ₦15,000
Subtract the wholesale purchase price (₦65,000) from the retail selling price (₦80,000).

Key Concept

The Output (Value Added) method measures national income by summing the net value added at each stage of production to prevent double counting.
Question 38Question

A wheat farmer sells harvested wheat to a flour mill for ₦150,000. The flour mill processes the wheat into flour and sells it to a bakery for ₦220,000. The bakery uses the flour to produce bread, which is sold to final consumers for ₦300,000. Using the output (value added) method of national income accounting, what is the net contribution of this production chain to Gross Domestic Product (GDP)?

Show answer & explanation

Answer: ₦300,000

Answer

The net contribution of this production chain to GDP is ₦300,000.
The output (value added) method measures GDP by taking the gross value of output at each stage of production and subtracting the cost of intermediate consumption. The farmer adds ₦150,000, the mill adds ₦70,000 (₦220,000 - ₦150,000), and the bakery adds ₦80,000 (₦300,000 - ₦220,000). Summing these gives ₦300,000, which is equal to the value of the final consumer product.

Step-by-Step Solution

1
Calculate the value added by the wheat farmer
Value Added = ₦150,000 - ₦0 = ₦150,000
The raw wheat is sold for ₦150,000 with zero intermediate input costs recorded.
2
Calculate the value added by the flour mill
Value Added = ₦220,000 - ₦150,000 = ₦70,000
The mill buys wheat for ₦150,000 and sells flour for ₦220,000.
3
Calculate the value added by the bakery
Value Added = ₦300,000 - ₦220,000 = ₦80,000
The bakery buys flour for ₦220,000 and sells bread to consumers for ₦300,000.
4
Sum the value added across all stages to find total GDP contribution
Total Value Added = ₦150,000 + ₦70,000 + ₦80,000 = ₦300,000
The output method sums the net additions to output at each production stage to avoid double counting.

Question 39Question

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?

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 40Question

The national income statistics for the Republic of Eldoria in a given fiscal year record the following expenditure components (in millions of dollars):

- Household Consumption Expenditure (CC): $420\$420
- Gross Private Domestic Investment (II): $150\$150
- Government Final Expenditure (GG): $180\$180
- Export Revenues (XX): $85\$85
- Import Expenditures (MM): $95\$95
- Net Factor Income Paid to Abroad: $15\$15

What is Eldoria's Gross National Product (GNPGNP) at market prices?

Show answer & explanation

Answer: $725\$725 million

Answer

The Gross National Product (GNP) at market prices is $725\$725 million.
The expenditure approach defines GDP=C+I+G+(XM)GDP = C + I + G + (X - M). Substituting the given figures gives GDP=420+150+180+(8595)=740GDP = 420 + 150 + 180 + (85 - 95) = 740 million dollars. To find GNPGNP, net factor income from abroad is added. Since net factor income was paid to abroad (an outflow of 15 million dollars), NFIA=15NFIA = -15 million dollars. Therefore, GNP=74015=725GNP = 740 - 15 = 725 million dollars.

Step-by-Step Solution

1
Calculate Gross Domestic Product (GDP) using the expenditure formula: GDP=C+I+G+(XM)GDP = C + I + G + (X - M)
GDP=420+150+180+(8595)=750+(10)=$740GDP = 420 + 150 + 180 + (85 - 95) = 750 + (-10) = \$740 million
The expenditure approach sums consumption, investment, government spending, and net exports (exports minus imports).
2
Determine Net Factor Income from Abroad (NFIA)
Since net factor income is paid to abroad (outflow), NFIA=$15NFIA = -\$15 million
Factor income flowing out of the domestic economy reduces the national income earned by citizens.
3
Convert GDP to GNP using the relation: GNP=GDP+NFIAGNP = GDP + NFIA
GNP=740+(15)=$725GNP = 740 + (-15) = \$725 million
Gross National Product measures total output created by residents of a country, regardless of location.
