Question 1Question

Which of the following activities presents a major difficulty in calculating national income because it is non-monetized?

Show answer & explanation

Answer: Subsistence farming output consumed directly by the farm household

Answer

Subsistence farming output consumed directly by the farm household
Subsistence agricultural output is consumed directly by the farmers who produce it. Because these products never enter the formal market, no prices or financial records exist for them, making it very difficult to accurately estimate their value in national income calculations.

Step-by-Step Solution

1
Identify the core problem described in national income accounting
The problem relates to non-monetized production.
Non-monetized activities do not pass through a market, so market prices are unavailable for valuation.
2
Evaluate the given options to find the non-market economic activity
Subsistence farm production is consumed internally by the producer without any price or monetary transaction occurring.
Because no money changes hands, national income statisticians must estimate or impute values, leading to measurement inaccuracies.

Question 2Question

An economy records a Gross Domestic Product (GDP) of 850 million Naira. The factor income earned by citizens from abroad is 30 million Naira, while factor income paid to foreigners within the domestic economy is 70 million Naira. If the capital consumption allowance (depreciation) is 65 million Naira, what is the Net National Product (NNP) of the country in million Naira?

Show answer & explanation

Answer: 745

Answer

The Net National Product (NNP) of the country is 745 million Naira.
To determine the Net National Product (NNP), first calculate Net Factor Income from Abroad (NFIA) as factor income from abroad (3030 million Naira) minus factor income paid abroad (7070 million Naira), yielding 40-40 million Naira. Gross National Product (GNP) is then calculated as GDP+NFIA=850+(40)=810\text{GDP} + \text{NFIA} = 850 + (-40) = 810 million Naira. Finally, subtract capital consumption allowance (6565 million Naira) from GNP to get NNP=81065=745\text{NNP} = 810 - 65 = 745 million Naira.

Step-by-Step Solution

1
Calculate Net Factor Income from Abroad (NFIA)
NFIA = 3070=4030 - 70 = -40 million Naira
Net Factor Income from Abroad is the difference between income received from abroad by residents and income paid to non-residents domestically.
2
Calculate Gross National Product (GNP)
GNP = 850+(40)=810850 + (-40) = 810 million Naira
GNP is obtained by adjusting GDP for Net Factor Income from Abroad.
3
Calculate Net National Product (NNP)
NNP = 81065=745810 - 65 = 745 million Naira
NNP is obtained by subtracting capital consumption allowance (depreciation) from GNP.

Question 3Question

The following macroeconomic data (in billions of Dollars) is provided for a country in a given fiscal year:

ComponentAmount ($ billions)
Consumer Expenditure (CC)500
Gross Private Domestic Investment (II)150
Government Consumption & Investment (GG)200
Exports (XX)80
Imports (MM)100

Using the expenditure method, what is the Gross Domestic Product (GDPGDP) of the country?

Show answer & explanation

Answer: 830830 billion

Answer

830830 billion
Under the expenditure approach, GDPGDP is calculated as the sum of personal consumption expenditure (CC), gross private domestic investment (II), government purchases (GG), and net exports (XMX - M). Substituting the given values yields 500+150+200+(80100)=85020=830500 + 150 + 200 + (80 - 100) = 850 - 20 = 830 billion dollars.

Step-by-Step Solution

1
Identify the national expenditure formula for calculating Gross Domestic Product (GDP).
GDP=C+I+G+(XM)GDP = C + I + G + (X - M)
The expenditure method sums private consumption, investment, government expenditure, and net exports.
2
Calculate Net Exports (XMX - M).
Net Exports =80100=20= 80 - 100 = -20 billion dollars
Imports must be subtracted from exports to derive net external trade expenditure.
3
Sum all expenditure components together.
GDP=500+150+200+(20)=830GDP = 500 + 150 + 200 + (-20) = 830 billion dollars
Adding consumption, investment, government purchases, and net exports gives the total GDP.

Question 4Question

In national income accounting, non-monetized activities such as unpaid housework performed by family members are included in official Gross Domestic Product (GDP) calculations.

Show answer & explanation

Answer: False

Answer

The statement is False. Unpaid household services and non-monetized activities are excluded from Gross Domestic Product (GDP) estimations because no money changes hands, creating a major practical difficulty in measuring total national output.
Unpaid domestic work does not enter the market mechanism, so no prices or transactional data exist to measure its value. Consequently, statistical agencies omit these non-monetized activities, which remains a primary conceptual and practical problem in national income measurement.

Step-by-Step Solution

1
Examine the role of non-monetized household activities in economic accounting.
Unpaid housework generates utility and productive output but lacks a market price.
National income accounting depends primarily on recorded monetary transactions in organized markets.
2
Determine if non-market domestic activities are included in official GDP statistics.
They are omitted from official national income figures.
The absence of transaction receipts makes calculating an accurate monetary valuation extremely difficult.

Question 5Question

In a given year, a country recorded a Nominal Gross Domestic Product (GDP) of $500 billion\$500\text{ billion}. The GDP deflator for the year was 125125 (with a base year index of 100100), and the total population was 50 million50\text{ million}. What was the Real Per Capita Income of the country in dollars?

Show answer & explanation

Answer: 8000

Answer

The Real Per Capita Income of the country is $8,000.
To compute the Real Per Capita Income, Nominal GDP is first converted to Real GDP using the GDP deflator: $500 billion125×100=$400 billion\frac{\$500\text{ billion}}{125} \times 100 = \$400\text{ billion}. Dividing this real income figure by the population of 50 million50\text{ million} gives an average real per capita income of $8,000\$8,000.

Step-by-Step Solution

1
Deflate Nominal GDP to obtain Real GDP
Real GDP = $400 billion
Real GDP removes the inflationary effect measured by the GDP deflator.
2
Divide Real GDP by the population size
Real Per Capita Income = $8,000
Per capita real income measures average real economic output per person.

Question 6Question

When computing national income using the output method, an economist includes both the full value of raw timber sold to a furniture maker and the final market value of the furniture produced from that timber. Which difficulty in national income accounting is created by this procedure?

Show answer & explanation

Answer: Double counting of national output

Answer

Double counting of national output
The correct answer is double counting of national output. In national income accounting using the output method, only the value added at each stage or the value of final goods should be counted. Including the intermediate good (raw timber) along with the final good (furniture) results in counting the input's value twice, which artificially inflates national income.

Step-by-Step Solution

1
Identify the nature of raw timber in the production process.
Raw timber is an intermediate good used to manufacture furniture.
Intermediate goods are inputs already embodied in the value of the final good.
2
Analyze the impact of adding intermediate goods to final goods.
The value of raw timber is counted once as an input and a second time as part of the furniture's final price.
This leads directly to the problem of double counting in national income statistics.

Using the expenditure approach, what is the Net National Product at factor cost (NNPfcNNP_{fc}) for this economy?

Show answer & explanation

Answer: 705705 billion

Answer

705705 billion
The expenditure method sums consumption, investment, government spending, and net exports to calculate GDPmpGDP_{mp} (450+210+15020=790450 + 210 + 150 - 20 = 790 billion). Adding net factor income from abroad gives GNPmpGNP_{mp} (775775 billion). Subtracting depreciation yields NNPmpNNP_{mp} (735735 billion), and deducting net indirect taxes (5020=3050 - 20 = 30 billion) gives NNPfc=705NNP_{fc} = 705 billion. Transfer payments are excluded to avoid double counting.

Step-by-Step Solution

1
Calculate Gross Domestic Product at market prices (GDPmpGDP_{mp}) using the expenditure components: C+I+G+(XM)C + I + G + (X - M)
GDPmp=450+(180+30)+150+(90110)=790GDP_{mp} = 450 + (180 + 30) + 150 + (90 - 110) = 790 billion
Gross domestic investment equals gross domestic fixed capital formation plus change in stocks. Transfer payments are excluded as they are non-productive transactions.
2
Adjust GDPmpGDP_{mp} for Net Factor Income from Abroad (NFIANFIA) to find Gross National Product at market prices (GNPmpGNP_{mp})
GNPmp=790+(15)=775GNP_{mp} = 790 + (-15) = 775 billion
GNPmp=GDPmp+NFIAGNP_{mp} = GDP_{mp} + NFIA.
3
Deduct depreciation (consumption of fixed capital) to determine Net National Product at market prices (NNPmpNNP_{mp})
NNPmp=77540=735NNP_{mp} = 775 - 40 = 735 billion
Net national aggregate equals gross national aggregate minus capital consumption.
4
Convert NNPmpNNP_{mp} to Net National Product at factor cost (NNPfcNNP_{fc})
NNPfc=73550+20=705NNP_{fc} = 735 - 50 + 20 = 705 billion
Factor cost is obtained by deducting indirect taxes and adding subsidies (NNPfc=NNPmpIndirect Taxes+SubsidiesNNP_{fc} = NNP_{mp} - \text{Indirect Taxes} + \text{Subsidies}).

Question 8Question

The table below presents the market transactions across three stages in the production of wooden furniture:

Stage of ProductionOutput Value (₦)Cost of Intermediate Inputs (₦)
Logging40,0000
Sawmilling75,00040,000
Furniture Manufacturing130,00075,000

What is the total net contribution of this production chain to Gross Domestic Product (GDP) using the output method?

Show answer & explanation

Answer: ₦130,000

Answer

The total net contribution to Gross Domestic Product (GDP) is ₦130,000.
Under the output (value added) method of national income accounting, contribution to GDP is determined by summing the value added at each stage of production. Value added is equal to gross output value minus intermediate input costs: Logging adds ₦40,000, Sawmilling adds ₦35,000 (₦75,000 - ₦40,000), and Furniture Manufacturing adds ₦55,000 (₦130,000 - ₦75,000). Total contribution to GDP is ₦40,000 + ₦35,000 + ₦55,000 = ₦130,000, which also corresponds directly to the final sale value of the consumer product.

Step-by-Step Solution

1
Calculate the value added at each stage of production by subtracting intermediate input costs from output value.
Logging: 40,0000=40,000₦40,000 - ₦0 = ₦40,000; Sawmilling: 75,00040,000=35,000₦75,000 - ₦40,000 = ₦35,000; Furniture Manufacturing: 130,00075,000=55,000₦130,000 - ₦75,000 = ₦55,000.
The output method measures national income by isolating the net value created at each stage of production.
2
Sum the value added across all production stages.
Total Value Added=40,000+35,000+55,000=130,000\text{Total Value Added} = ₦40,000 + ₦35,000 + ₦55,000 = ₦130,000.
Summing net additions to output yields the actual total value of final goods produced without double counting.

$440 billion
To find Net National Product (NNP), first calculate Net Factor Income from Abroad (NFIA) by subtracting factor income paid to foreigners (50billion)fromfactorincomeearnedfromabroad(50 billion) from factor income earned from abroad ( 30 billion), giving -20billion.AddingNFIAtoGDPgivesGrossNationalProduct(GNP=20 billion. Adding NFIA to GDP gives Gross National Product (GNP = 500 billion - 20billion=20 billion = 480 billion). Finally, subtracting capital consumption allowance (40billion)fromGNPyieldsNNPequalto40 billion) from GNP yields NNP equal to 440 billion.

Step-by-Step Solution

1
Calculate Net Factor Income from Abroad (NFIA)
NFIA = Factor income from abroad - Factor income paid abroad = 30billion30 billion - 50 billion = -$20 billion
NFIA measures the net flow of income between domestic citizens earning abroad and foreign residents earning within the domestic economy.
2
Calculate Gross National Product (GNP)
GNP = GDP + NFIA = 500billion+(500 billion + (- 20 billion) = $480 billion
GNP accounts for the total economic output produced by citizens of a nation regardless of geographic boundary.
3
Calculate Net National Product (NNP)
NNP = GNP - Depreciation = 480billion480 billion - 40 billion = $440 billion
Deducting capital consumption allowance (depreciation) from GNP yields the net production available after accounting for capital wear and tear.

Valuation of inventory during price inflation
Aggregation of intermediate inputs with final output
Omission of unpaid domestic homemaking services

Matches

Show answer & explanation

Answer

Non-monetized subsistence production matches with causing underestimation in agrarian nations; inventory valuation during inflation matches with creating illusory expansion without physical increase; aggregation of intermediate inputs matches with double counting; and omission of unpaid domestic services matches with excluding activities lacking formal market prices.
Each difficulty in national income measurement is correctly paired with its economic consequence. Non-monetized subsistence production leads to an underestimation of output in rural developing nations; inflation creates nominal increases without real physical growth; counting intermediate goods alongside final output causes double counting; and unpaid domestic work is excluded due to the lack of monetary prices.

Step-by-Step Solution

1
Examine non-monetized subsistence production
Identified as a cause of severe national income undercount in agrarian developing economies.
Direct household consumption of agricultural yield bypasses monetary market channels.
2
Analyze price inflation effects on national income valuation
Determined that inflation inflates nominal values without increasing actual physical goods.
Nominal GDP measures output at prevailing market prices rather than constant real prices.
3
Evaluate the impact of counting intermediate inputs with final goods
Recognized this practice as the root cause of double counting.
The final price of a product already encompasses the economic value contributed by all intermediate production stages.
4
Assess unpaid domestic homemaking activities
Understood that such services are excluded because they lack monetary price tags.
National income accounting criteria require verifiable market transactions.

Question 11Question

In a given fiscal year, an economy records a National Income of ₦850 million. The accounting records reveal corporate profit taxes of ₦60 million, undistributed corporate profits of ₦40 million, social security contributions of ₦30 million, government transfer payments to households of ₦50 million, and personal direct taxes of ₦70 million. What is the Disposable Personal Income of this economy in millions of Naira?

Show answer & explanation

Answer: 700

Answer

700 million Naira
Starting from National Income of ₦850 million, we subtract corporate profit taxes (₦60 million), undistributed corporate profits (₦40 million), and social security contributions (₦30 million), while adding transfer payments (₦50 million) to arrive at Personal Income of ₦770 million. Subtracting personal direct taxes of ₦70 million yields a Disposable Personal Income of ₦700 million.

Step-by-Step Solution

1
Calculate Personal Income from National Income by deducting earnings not received by households (corporate taxes, retained earnings, social security payments) and adding income received but not earned in current production (transfer payments).
Personal Income = ₦850 million - ₦60 million - ₦40 million - ₦30 million + ₦50 million = ₦770 million
Personal Income measures the total earnings received by households from all sources prior to personal direct taxation.
2
Deduct personal direct taxes from Personal Income to find Disposable Personal Income.
Disposable Personal Income = ₦770 million - ₦70 million = ₦700 million
Disposable Personal Income represents the net amount remaining for spending and personal savings after paying direct taxes.

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.

Answer

Stage 1 matches Net Value Added of ₦120,000; Stage 2 matches Net Value Added of ₦150,000; Stage 3 matches Net Value Added of ₦210,000; Stage 4 matches Net Value Added of ₦170,000.
The output (value added) method measures national income by summing the net incremental value created at each stage of production. For each stage, Value Added = Gross Value of Output minus Cost of Intermediate Inputs. This ensures intermediate goods are counted only once and eliminates double counting.

Step-by-Step Solution

1
Calculate Value Added for Stage 1
Gross Output (₦120,000) - Intermediate Purchases (₦0) = ₦120,000
The initial primary production stage has no intermediate cost inputs.
2

Question 15Question

An economy has a Gross National Product (GNP) of N750\text{N}750 million and a Net National Product (NNP) of N680\text{N}680 million. What is the value of the capital consumption allowance?

Show answer & explanation

Answer: N70\text{N}70 million

Answer

N70\text{N}70 million
The correct answer is derived by subtracting Net National Product (NNP) from Gross National Product (GNP). Since NNP reflects total production minus wear and tear on capital goods (depreciation), the difference between N750\text{N}750 million and N680\text{N}680 million equals the capital consumption allowance of N70\text{N}70 million.

Step-by-Step Solution

1
Identify the relationship between Gross National Product (GNP), Net National Product (NNP), and Capital Consumption Allowance (Depreciation).
NNP=GNPDepreciation\text{NNP} = \text{GNP} - \text{Depreciation}
Net National Product represents gross national output after accounting for the depreciation of capital assets.
2
Rearrange the identity to solve for Depreciation (Capital Consumption Allowance).
Capital Consumption Allowance=GNPNNP\text{Capital Consumption Allowance} = \text{GNP} - \text{NNP}
Isolating the depreciation component allows direct computation from given figures.
3
Substitute the given numerical values into the rearranged formula.
Capital Consumption Allowance=N750 millionN680 million=N70 million\text{Capital Consumption Allowance} = \text{N}750\text{ million} - \text{N}680\text{ million} = \text{N}70\text{ million}
Subtracting N680\text{N}680 million from N750\text{N}750 million yields the correct depreciation value.

Transfer payments ( 15 million) are excluded as non-factor receipts. Adjusting for Net Factor Income from Abroad (-10million)yieldsthecorrectGrossNationalProductof10 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(150m) + Profits ( 45m) + Rent (25m)+Interest(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(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.

GDPmp=650+220+310+(140160)=1160GDP_{mp} = 650 + 220 + 310 + (140 - 160) = 1160 million dollars.
The expenditure method sums private consumption, gross investment, government purchases, and net exports (XMX - M) to determine total domestic output.

Adjust GDPmpGDP_{mp} by adding Net Factor Income from Abroad (NFIANFIA) to derive Gross National Product at market price (GNPmpGNP_{mp}): GNPmp=GDPmp+NFIAGNP_{mp} = GDP_{mp} + NFIA.
GNPmp=1160+25=1185GNP_{mp} = 1160 + 25 = 1185 million dollars.
Gross National Product measures total income earned by residents of a nation, requiring the inclusion of net factor income earned from overseas.

Question 18Question

Match each stage of production in a leather shoe manufacturing process with its correct Value Added contribution to National Income.

Click a left item, then click its matching right item

Items

Cattle Ranching (Raw hides sold for ₦4,000; Intermediate inputs = ₦0)
Leather Tanning (Tanned leather sold for ₦10,000; Purchases raw hides for ₦4,000)
Shoe Manufacturing (Shoes sold to retailer for ₦18,000; Purchases tanned leather for ₦10,000)
Retail Distribution (Shoes sold to consumer for ₦25,000; Purchases shoes for ₦18,000)

Matches

Show answer & explanation

Answer

Cattle Ranching matches Value Added = ₦4,000; Leather Tanning matches Value Added = ₦6,000; Shoe Manufacturing matches Value Added = ₦8,000; Retail Distribution matches Value Added = ₦7,000.
Each stage's contribution to national income is determined by subtracting the value of intermediate inputs purchased from the value of gross output generated at that specific stage.

Step-by-Step Solution

1
Calculate Value Added for Cattle Ranching
Value Added = ₦4,000 - ₦0 = ₦4,000
Value added is calculated as Gross Output minus Intermediate Inputs.
2
Calculate Value Added for Leather Tanning
Value Added = ₦10,000 - ₦4,000 = ₦6,000
Subtract the cost of raw hides from the selling price of tanned leather.
3
Calculate Value Added for Shoe Manufacturing
Value Added = ₦18,000 - ₦10,000 = ₦8,000
Subtract the cost of tanned leather from the wholesale price of shoes.
4
Calculate Value Added for Retail Distribution
Value Added = ₦25,000 - ₦18,000 = ₦7,000
Subtract the wholesale price of shoes from the final retail price.

Key Concept

The Output (Value Added) Method calculates National Income by summing the net value added at each production stage (Gross Output minus Intermediate Consumption) to avoid double counting.
Question 19Question

In a four-sector open economy, national income equilibrium is maintained when total leakages (withdrawals) equal total injections. If savings (SS) is \150million,taxation(150 million, taxation ( T )is$100million,imports() is \$100 million, imports ( M )are$80million,investment() are \$80 million, investment ( I )is$180million,andgovernmentexpenditure() is \$180 million, and government expenditure ( G )is$110million,whatistherequiredvalueofexports() is \$110 million, what is the required value of exports ( X$) to maintain equilibrium?

Show answer & explanation

Answer: \$40 million

Answer

\$40 million is required for exports to achieve equilibrium in the circular flow of income.
The correct answer is \40million.Inafoursectoropeneconomy,equilibriumrequirestotalleakages(40 million. In a four-sector open economy, equilibrium requires total leakages ( S + T + M )toequaltotalinjections() to equal total injections ( I + G + X ).Summingleakagesyields).

To reach equilibrium, exports ( X )mustaccountforthedifference:) must account for the difference: 330 - 290 = 40$ million.

Step-by-Step Solution

1
Identify the equilibrium condition for a four-sector circular flow of income
Total Leakages (WW) = Total Injections (JJ)
Equilibrium occurs where withdrawals from the circular flow equal additions to it.
2
Calculate total leakages (W=S+T+MW = S + T + M)
W=150+100+80=$330 millionW = 150 + 100 + 80 = \$330\text{ million}
Savings (SS), Taxation (TT), and Imports (MM) represent money flowing out of the domestic circular flow.
3
Set up the injection equation (J=I+G+XJ = I + G + X) and solve for XX
330=180+110+X    330=290+X    X=40 million330 = 180 + 110 + X \implies 330 = 290 + X \implies X = 40\text{ million}
Investment (II), Government Spending (GG), and Exports (XX) are injections, so XX must balance the remaining leakage shortfall.

Question 20Question

In national income accounting, excluding government transfer payments—such as unemployment benefits and old-age pensions—causes an underestimation of gross domestic product.

Show answer & explanation

Answer: False

Answer

The statement is False. Transfer payments are excluded from national income estimates because they do not reflect current production, and including them would lead to double counting.
Transfer payments are non-productive transactions that redistribute purchasing power without creating new output. Excluding them is necessary to prevent double counting, meaning their omission does not cause an underestimation of true national product.

Step-by-Step Solution

1
Identify the nature of government transfer payments
Transfer payments (e.g., pensions, unemployment benefits) are receipts given without any direct flow of goods or services in return.
National income accounting measures the total monetary value of final goods and services produced in an economy during a given period.
2
Analyze the impact of including or excluding transfer payments
The income used to fund transfer payments is already recorded when earned by taxpayers. Counting the disbursement again as new output would double-count that income.
Double counting distorts national income figures by overstating the true output of the economy.
3
Evaluate the statement's claim
Excluding transfer payments maintains accuracy and prevents double counting rather than causing an underestimation of output.
Therefore, the statement claiming that excluding transfer payments underestimates gross domestic product is false.
