Question 9541Question →

Match each category of public expenditure listed on the left with its correct operational definition or fiscal characteristic on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

The correct pairings are: Transfer Payments matches with unilateral disbursements that produce no immediate output; Capital Expenditure matches with investment outlays on durable physical assets expanding capacity; Non-Developmental Recurrent Expenditure matches with routine administrative overheads and public debt servicing; Developmental Expenditure matches with spending targeted directly at fostering economic growth and social welfare.

Each expenditure type strictly aligns with its economic role: Transfer Payments involve non-reciprocal payments; Capital Expenditure creates physical infrastructure assets; Non-Developmental Recurrent Expenditure funds basic administrative operations and debt interest; and Developmental Expenditure directly enhances economic growth and socio-economic capabilities.

Step-by-Step Solution

1

Analyze Transfer Payments

Identified as unilateral redistributions (e.g., pensions, subsidies) where government receives no direct current product or service in return.

By definition, transfer payments are non-reciprocal transactions.

2

Analyze Capital Expenditure

Identified as spending on long-term assets such as highways, bridges, and power stations.

Capital expenditures accumulate fixed assets and enhance the future productive capacity of the economy.

3

Analyze Non-Developmental Recurrent Expenditure

Identified as spending on governance administration, defense, maintenance, and debt service.

These spending items are essential for state maintenance but do not directly generate social overhead capital or long-term growth.

4

Analyze Developmental Expenditure

Identified as expenditure on social infrastructure, health, education, and agricultural support.

Such investments contribute directly to human capital enhancement and economic development.

Question 9542Question →

In a closed three-sector economy consisting of households, business firms, and the government, planned household savings ( $S$ ) is $\$65\text{ billion}$ , net government tax revenue ( $T$ ) is $\$35\text{ billion}$ , and private investment expenditure ( $I$ ) is $\$45\text{ billion}$ . For the circular flow of income to be in equilibrium, what must be the level of government expenditure ( $G$ )?

\$15\text{ billion}

\$55\text{ billion}

\$75\text{ billion}

\$100\text{ billion}

Show answer & explanation

Answer: $\$55\text{ billion}$

Answer

The level of government expenditure required for circular flow equilibrium is

\$55\text{ billion}

.

In a three-sector model of the circular flow of income (Households, Business Firms, and Government), national income equilibrium requires total leakages (

S + T

) to equal total injections (

I + G

). Adding household savings (

\ me\$65\text{ billion}

) and government taxes (

\ me\$35\text{ billion}

) gives total leakages of

\$100\text{ billion}

. Setting investment (

\ me\$45\text{ billion}

) plus government expenditure (

G

) equal to

\$100\text{ billion}

yields

G = \$55\text{ billion}

.

Step-by-Step Solution

1

Identify total leakages (withdrawals) from the circular flow

Total Leakages =

S + T = \$65\text{ billion} + \$35\text{ billion} = \$100\text{ billion}

In a three-sector economy, leakages consist of savings (

S

) and net taxes (

T

).

2

Set total injections equal to total leakages

Total Injections (

I + G

) = Total Leakages (

S + T

) =

\$100\text{ billion}

Equilibrium in the circular flow of income occurs when total planned injections equal total planned leakages.

3

Solve for government expenditure (

G

)

\$45\text{ billion} + G = \$100\text{ billion} \implies G = \$100\text{ billion} - \$45\text{ billion} = \$55\text{ billion}

Subtract investment (

I

) from total injections to find the required government expenditure (

G

).

Question 9543Question →

An ad valorem consumption tax is levied at a flat rate of $10\%$ on all retail purchases. A low-income household earning $\text{N}100,000$ monthly spends $\text{N}60,000$ on taxable goods, while a high-income household earning $\text{N}500,000$ monthly spends $\text{N}150,000$ on taxable goods. Based on the effective tax rate relative to total income, which system of taxation does this tax illustrate?

A regressive tax system, because the effective tax rate decreases as income rises

A progressive tax system, because the absolute amount of tax paid increases with higher income

A proportional tax system, because a uniform tax rate of

10\%

is charged on all purchases

A direct tax system, because the tax is assessed directly on household expenditure

Show answer & explanation

Answer: A regressive tax system, because the effective tax rate decreases as income rises

Answer

A regressive tax system, because the effective tax rate decreases as income rises

The correct answer is that the scenario illustrates a regressive tax system because the effective tax rate relative to total income falls as income increases. The low-income earner pays

6\%

of total income in tax (

\text{N}6,000

out of

\text{N}100,000

), while the high-income earner pays

3\%

of total income (

\text{N}15,000

out of

\text{N}500,000

).

Step-by-Step Solution

1

Calculate the amount of tax paid by each household

Low-income household tax =

10\% \text{ of } \text{N}60,000 = \text{N}6,000

. High-income household tax =

10\% \text{ of } \text{N}150,000 = \text{N}15,000

.

Tax paid is computed by applying the

10\%

rate to taxable consumption expenditure.

2

Compute the effective tax rate (tax paid as a percentage of total income) for both households

Low-income effective rate =

\frac{\text{N}6,000}{\text{N}100,000} \times 100 = 6\%

. High-income effective rate =

\frac{\text{N}15,000}{\text{N}500,000} \times 100 = 3\%

.

System classification requires analyzing the tax burden as a proportion of overall income.

3

Determine the system of taxation based on the change in effective rate relative to income

As income increases from

\text{N}100,000

to

\text{N}500,000

, the effective tax rate falls from

6\%

to

3\%

, defining a regressive tax system.

By definition, a tax system where higher income earners pay a smaller fraction of their income in tax is regressive.

Question 9544Question →

Match each firm growth scenario on the left with its corresponding category of economy or diseconomy of scale on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Bulk purchasing of feed at discounted prices matches Commercial internal economy of scale; communication bottlenecks from administrative expansion match Managerial internal diseconomy of scale; shared industrial facilities benefiting local tanneries match External economy of scale.

Bulk purchasing is an internal commercial cost advantage gained directly by an individual firm expanding its purchases. Communication breakdowns due to excessive administrative layers represent internal managerial inefficiencies (diseconomies). Shared regional infrastructure benefits all firms within the industry location, defining an external economy of scale.

Step-by-Step Solution

1

Analyze the first scenario regarding bulk purchasing.

Discounts gained by buying in large quantities reduce unit purchasing costs for the individual firm, identifying it as a commercial internal economy of scale.

The cost advantage arises from bulk buying within the individual firm.

2

Analyze the second scenario regarding administrative delays and communication issues.

Inefficiency caused by too many hierarchical layers increases average unit cost, identifying it as a managerial internal diseconomy of scale.

Administrative friction occurs internally due to over-expansion.

3

Analyze the third scenario regarding a shared effluent treatment facility.

A facility provided for the entire industrial location lowers costs for all local tanneries, identifying it as an external economy of scale.

The benefit originates outside the individual firm from general industry development.

Question 9545Question →

In an agro-processing factory in Kwara State where sugarcane is crushed to manufacture refined sugar, molasses is automatically yielded as a byproduct of the same production run. If an increase in consumer demand for sugar leads to a rise in its market price and output, the market supply of molasses will decrease because processing resources are diverted to sugar.

True

False

Show answer & explanation

Answer: False

Answer

The statement is False. Sugar and molasses are in joint (complementary) supply, meaning an increase in the production of sugar leads to an increase—not a decrease—in the supply of molasses.

The statement is false because refined sugar and molasses exhibit joint (complementary) supply. When two goods are yielded together from a single production process, an increase in the production of the primary good inherently increases the total availability and supply of the secondary byproduct.

Step-by-Step Solution

1

Identify the relationship between the two goods

Refined sugar and molasses are derived simultaneously from processing the same raw material (sugarcane). Therefore, they are in joint or complementary supply.

Determining whether goods are in joint, competitive, composite, or derived supply dictates how changes in the production of one impact the supply of the other.

2

Analyze the effect of a price/demand increase for the main product

Higher market demand and prices for refined sugar incentivize factory owners to expand total sugarcane crushing operations.

According to the law of supply, higher prices induce higher output of the primary product.

3

Deduce the effect on the joint product (molasses)

Expanding sugarcane crushing yields a larger quantity of molasses as an inevitable byproduct, shifting the supply curve of molasses to the right.

In joint supply, the supply of the byproduct moves in the same direction as the supply of the main product.

Question 9546Question →

Match each obstacle to economic development in developing nations listed on the left with its precise macroeconomic mechanism or structural manifestation on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

The correct matches associate: (1) Vicious Cycle of Low Capital Formation with low income restricting savings and capital investment; (2) High Demographic Dependency Ratio with resource diversion toward immediate consumption; (3) Structural Economic Dualism with the coexistence of modern urban and traditional rural sectors; and (4) Primary Product Export Dependence with terms-of-trade deterioration and foreign exchange constraints.

Each obstacle is matched to its core economic definition: the vicious cycle of capital formation is driven by low savings capacity; high dependency ratios divert potential savings into consumption; structural dualism reflects the urban-rural sectoral divide; and primary export reliance causes foreign exchange bottlenecks due to unfavorable terms of trade.

Step-by-Step Solution

1

Analyze the financial cycle of poverty and capital scarcity

Identify that low per capita income creates low savings, leading directly to low capital investment.

Ragnar Nurkse's vicious cycle hypothesis demonstrates how supply-side capital formation is constrained by low savings.

2

Evaluate demographic factors impacting national saving

Connect high dependency ratios with heavy consumption burdens.

A high proportion of non-working youth increases the dependency burden, reducing the aggregate savings rate.

3

Examine internal structural inequality in developing economies

Match structural dualism to the coexistence of modern urban enclaves and traditional rural sectors.

Dualistic economy models (such as Arthur Lewis's framework) explain the structural divide between high-tech urban firms and subsistence agriculture.

4

Assess external trade bottlenecks affecting developing nations

Link primary product reliance with declining terms of trade and foreign exchange deficits.

Primary products face inelastic demand and declining terms of trade in international markets compared to manufactured imports.

\Delta Y

) and Good

X

(

\Delta X

)

\Delta Y = -4

(reduction of 4 units of

Y

) and

\Delta X = +2

Question 9548Question →

A developing country produces only two commodities: Cocoa and Steel. If a technical innovation occurs that significantly improves agricultural yields for Cocoa without affecting Steel production efficiency, which of the following best describes the structural change in the nation's Production Possibility Curve (PPC)?

The curve rotates outward along the Cocoa axis while remaining anchored at the original maximum limit on the Steel axis.

The entire curve shifts outward parallel to its original position across both the Cocoa and Steel axes.

There is a movement downward along the existing curve from Steel production toward Cocoa production.

The monetary price of Cocoa falls, causing the opportunity cost of Steel to decrease to zero.

Show answer & explanation

Answer: The curve rotates outward along the Cocoa axis while remaining anchored at the original maximum limit on the Steel axis.

Answer

The Production Possibility Curve rotates outward along the Cocoa axis while maintaining its original intercept on the Steel axis.

When technological progress benefits only one specific sector (in this case, Cocoa), the economy's maximum potential capacity to produce that single good increases, while the maximum potential output for the uninfluenced sector (Steel) remains constant. Graphically, this causes the Production Possibility Curve to pivot or rotate outward along the Cocoa axis while remaining attached to the same point on the Steel axis.

Step-by-Step Solution

1

Analyze the scope of the technological advancement.

The innovation specifically enhances productivity in Cocoa production while leaving Steel technology unchanged.

Targeted technology increases maximum potential output for only one commodity.

2

Determine the impact on the boundary endpoints (axis intercepts) of the PPC.

The maximum obtainable amount of Cocoa increases, moving its intercept outward, while the Steel intercept stays constant.

A PPC intercept represents maximum potential output when all resources are dedicated to producing a single good.

3

Differentiate between a full curve shift, a rotation, and a movement along the curve.

An asymmetric increase in capacity results in an outward rotation (pivot) rather than a parallel shift or a movement along the static curve.

Unbalanced growth pivots the curve from the axis of the unaffected commodity.

Question 9549Question →

A single-price monopolist operates with a total revenue function given by $TR = 120Q - 3Q^2$ and a total cost function given by $TC = 100 + 20Q + 2Q^2$ , where $Q$ represents the output quantity in units and figures are in Naira (₦). What is the profit-maximizing price charged by the firm?

₦90

₦60

₦40

₦20

Show answer & explanation

Answer: ₦90

Answer

The profit-maximizing price is ₦90.

To maximize profits, a monopolist produces where marginal revenue equals marginal cost (

MR = MC

). Differentiating total revenue

TR = 120Q - 3Q^2

yields

MR = 120 - 6Q

, and differentiating total cost

TC = 100 + 20Q + 2Q^2

yields

MC = 20 + 4Q

. Setting

120 - 6Q = 20 + 4Q

solves to

Q = 10

units. The demand equation for price is

P = \frac{TR}{Q} = 120 - 3Q

. Substituting

Q = 10

gives

P = 120 - 3(10) = ₦90

.

Step-by-Step Solution

1

Derive the Marginal Revenue (MR) and Marginal Cost (MC) functions.

MR = \frac{dTR}{dQ} = 120 - 6Q

and

MC = \frac{dTC}{dQ} = 20 + 4Q

.

Profit maximization occurs at the output level where Marginal Revenue equals Marginal Cost.

2

Set MR equal to MC to solve for profit-maximizing output quantity (

Q

).

120 - 6Q = 20 + 4Q \implies 100 = 10Q \implies Q = 10

units.

Equating MR and MC identifies the specific output level that maximizes total profit.

3

Determine the Average Revenue (Demand) equation and solve for Price (

P

).

P = \frac{TR}{Q} = 120 - 3Q

. Substituting

Q = 10

yields

P = 120 - 3(10) = ₦90

.

Based on the expenditure method of measuring national income, what is the value of Gross Domestic Fixed Capital Formation?

\$175

\$235

billion

\$275

billion

\$115

billion

Show answer & explanation

Answer: $\$235$ billion

Answer

The Gross Domestic Fixed Capital Formation is

\$235

billion.

To find the Gross Domestic Fixed Capital Formation, we first calculate

GDP_{mp}

from

NNP_{fc}

:
1.

NNP_{mp} = NNP_{fc} + \text{Indirect Taxes} - \text{Subsidies} = 850 + 70 - 20 = \$900

billion.
2.

GNP_{mp} = NNP_{mp} + \text{Depreciation} = 900 + 60 = \$960

billion.
3.

GDP_{mp} = GNP_{mp} - NFIA = 960 - (-30) = \$990

billion.

Under the expenditure approach,

GDP_{mp} = C + I_{\text{fixed}} + \Delta\text{Stock} + G + (X - M)

.
Substituting the given values:

990 = 520 + I_{\text{fixed}} + 40 + 210 - 15

990 = I_{\text{fixed}} + 755 \implies I_{\text{fixed}} = \$235

billion.

Step-by-Step Solution

1

Convert Net National Product at factor cost (

NNP_{fc}

) to Net National Product at market prices (

NNP_{mp}

).

NNP_{mp} = NNP_{fc} + \text{Indirect Taxes} - \text{Subsidies} = 850 + 70 - 20 = \$900

billion.

Market price valuation includes net indirect taxes (indirect taxes minus subsidies).

2

Convert

NNP_{mp}

to Gross National Product at market prices (

GNP_{mp}

).

GNP_{mp} = NNP_{mp} + \text{Depreciation} = 900 + 60 = \$960

billion.

Gross aggregates include capital consumption allowance (depreciation).

3

Convert

GNP_{mp}

to Gross Domestic Product at market prices (

GDP_{mp}

).

GDP_{mp} = GNP_{mp} - NFIA = 960 - (-30) = 960 + 30 = \$990

billion.

Gross Domestic Product equals Gross National Product minus Net Factor Income from Abroad.

4

Apply the expenditure formula for

GDP_{mp}

to isolate Gross Domestic Fixed Capital Formation (

I_{\text{fixed}}

).

GDP_{mp} = C + I_{\text{fixed}} + \Delta\text{Stock} + G + (X - M) \implies 990 = 520 + I_{\text{fixed}} + 40 + 210 + (-15) \implies 990 = I_{\text{fixed}} + 755 \implies I_{\text{fixed}} = 990 - 755 = \$235

billion.

Total investment expenditure (Gross Capital Formation) consists of Gross Domestic Fixed Capital Formation plus Changes in Stocks.

Question 9551Question →

In a local market, the demand function for rice is given by $Q_d = 80 - 4P$ and the supply function is given by $Q_s = 20 + 6P$ , where $P$ is the price in Naira per bag. What is the market equilibrium price (in Naira)?

Show answer & explanation

Answer: 6

Answer

The market equilibrium price is 6 Naira.

At market equilibrium, quantity demanded equals quantity supplied (

Q_d = Q_s

). Setting

80 - 4P = 20 + 6P

leads to

60 = 10P

, which gives an equilibrium price of 6 Naira.

Step-by-Step Solution

1

Equate the demand function and the supply function to establish market equilibrium.

80 - 4P = 20 + 6P

Market equilibrium is defined as the price point where quantity demanded equals quantity supplied (

Q_d = Q_s

).

2

Collect like terms with price (

P

) on one side and constant numerical terms on the other side.

80 - 20 = 6P + 4P \implies 60 = 10P

Moving

-4P

to the right side changes its sign to

+4P

, and moving

20

to the left side changes its sign to

Question 9552Question →

A consumer allocating an income of $\text{₦}1,800$ between Good $X$ and Good $Y$ faces market prices of $P_x = \text{₦}40$ and $P_y = \text{₦}30$ per unit, respectively. The consumer's Marginal Rate of Substitution of Good $X$ for Good $Y$ is given by $MRS_{xy} = \frac{2Y}{X}$ . Assuming the consumer maximizes satisfaction subject to their budget constraint, how many units of Good $X$ will be consumed at equilibrium?

Show answer & explanation

Answer: 30

Answer

At consumer equilibrium under ordinal utility analysis, the optimal quantity of Good

X

consumed is 30 units.

At consumer equilibrium under ordinal utility, the tangency condition requires

MRS_{xy} = \frac{P_x}{P_y}

. Substituting

MRS_{xy} = \frac{2Y}{X}

and prices

P_x = 40

,

P_y = 30

gives

\frac{2Y}{X} = \frac{40}{30}

, which simplifies to

Y = \frac{2}{3}X

. Substituting

Y = \frac{2}{3}X

into the consumer's budget constraint

40X + 30Y = 1800

yields

40X + 30\left(\frac{2}{3}X\right) = 1800 \implies 60X = 1800 \implies X = 30

units.

Step-by-Step Solution

1

Equate the Marginal Rate of Substitution (

MRS_{xy}

) to the price ratio (

P_x / P_y

) to apply the tangency condition for ordinal utility equilibrium.

\frac{2Y}{X} = \frac{40}{30} \implies \frac{2Y}{X} = \frac{4}{3} \implies 6Y = 4X \implies Y = \frac{2}{3}X

Consumer equilibrium under ordinal utility requires that the slope of the indifference curve (

MRS_{xy}

) equals the slope of the budget line (

P_x / P_y

).

2

Substitute the expression for

Y

into the budget constraint equation

P_x X + P_y Y = I

.

40X + 30\left(\frac{2}{3}X\right) = 1800

To achieve maximum utility within income limits, the entire income of

\text{₦}1,800

must be spent on goods

X

and

Y

.

3

Simplify the equation and solve for the value of

X

.

40X + 20X = 1800 \implies 60X = 1800 \implies X = 30

Combining like terms gives a linear equation in

X

, yielding 30 units at equilibrium.

Key Concept

Consumer equilibrium under ordinal utility occurs where the highest attainable indifference curve is tangent to the budget line, satisfying

MRS_{xy} = \frac{P_x}{P_y}

alongside the budget constraint

P_x X + P_y Y = I

.

A small-scale manufacturer of woven baskets in Anambra State observes that at a market price of $\text{N}2,000$ per basket, weekly supply is $250$ units. When the market price rises to $\text{N}5,000$ per basket, weekly supply increases to $850$ units. Assuming a linear supply relationship of the form $Q_s = c + dP$ , what is the value of the autonomous supply constant $c$ ?

-150

150

0.2

-400

Show answer & explanation

Answer: $-150$

Answer

The autonomous supply constant

c

is

-150

.

The linear supply function is defined as

Q_s = c + dP

. Determining the price responsiveness parameter

d = \frac{\Delta Q_s}{\Delta P} = \frac{850 - 250}{5,000 - 2,000} = 0.2

, and substituting this back into

250 = c + 2,000(0.2)

yields

c = 250 - 400 = -150

.

Step-by-Step Solution

1

Set up linear supply equations using given price and quantity pairs

Equation 1:

250 = c + 2,000d

; Equation 2:

850 = c + 5,000d

The linear supply function follows the formula

Q_s = c + dP

.

2

Calculate the slope coefficient

d

d = \frac{\Delta Q_s}{\Delta P} = \frac{850 - 250}{5,000 - 2,000} = \frac{600}{3,000} = 0.2

The slope

d

measures the change in quantity supplied per unit change in price.

3

Substitute

d = 0.2

into Equation 1 to solve for the autonomous supply constant

c

250 = c + 2,000(0.2) \implies 250 = c + 400 \implies c = 250 - 400 = -150

Question 9554Question →

Country X exhibits a high population growth rate alongside low domestic savings, resulting in minimal capital formation per worker. According to Ragnar Nurkse's formulation of the vicious cycle of poverty on the supply side, which macroeconomic mechanism primarily perpetuates this low-level development trap?

Low real income leads to low capacity to save, which restricts capital accumulation, resulting in low productivity and sustained low real income.

Rapid GDP expansion automatically guarantees structural development, but foreign exchange volatility disrupts domestic price levels.

Foreign direct investment transactions are incorrectly categorized under the current account instead of the capital account, depressing official reserve balances.

Expanding government recurrent expenditure boosts long-term productive capacity at the same rate as capital expenditure, eliminating the investment gap.

Show answer & explanation

Answer: Low real income leads to low capacity to save, which restricts capital accumulation, resulting in low productivity and sustained low real income.

Answer

Low real income leads to low capacity to save, which restricts capital accumulation, resulting in low productivity and sustained low real income.

The supply side of the vicious cycle of poverty demonstrates how low level of real per capita income leads to a low capacity to save. Low savings result in low rates of investment and capital formation, which maintains low worker productivity and reinforces low real income.

Step-by-Step Solution

1

Analyze the supply side of Nurkse's vicious cycle of poverty

Identify the circular relationship: Low Income → Low Savings → Low Investment/Capital Formation → Low Productivity → Low Income.

Economic development requires capital accumulation; when income is low, consumption absorbs nearly all earnings, leaving little to save or invest.

2

Evaluate the role of population growth and capital formation

Rapid population growth increases the dependency ratio, further depressing per capita savings.

Higher dependency ratios increase consumption demands relative to production, tightening the low-savings constraint.

3

Differentiate correct structural mechanisms from distractor traps

Confirm that the correct mechanism focuses on real income, savings capacity, capital formation, and productivity linkages.

Equating growth with development or confusing public expenditure types does not capture the core mechanism of the poverty trap.

In an agricultural economy experiencing severe youth unemployment alongside rising food costs, commercial farming enterprise managers switch from labor-intensive methods to capital-intensive automated harvesting technologies to reduce unit operating expenses.

Under these combined conditions, how do the market-driven resolution of 'How to produce' and the state-imposed constraint on 'For whom to produce' interact to affect overall economic resource allocation?

Capital-intensive technology lowers private unit costs of production, but the price ceiling artificially depresses market revenue, causing aggregate output shortages that impede the equitable distribution of food to low-income households.

The price ceiling automatically redirects capital resources toward agricultural production, signaling market forces to resolve 'What to produce' by expanding food output to absorb unemployed youth.

Unemployed agricultural workers experience a decline in real income, which raises the equilibrium price of food and enables the uninhibited market mechanism to solve 'For whom to produce'.

Transitioning to automated technology eliminates the opportunity cost of farm land, causing explicit money costs and market prices to equalize under the price ceiling.

Show answer & explanation

Answer: Capital-intensive technology lowers private unit costs of production, but the price ceiling artificially depresses market revenue, causing aggregate output shortages that impede the equitable distribution of food to low-income households.

Answer

Capital-intensive technology lowers private unit costs of production, but the price ceiling artificially depresses market revenue, causing aggregate output shortages that impede the equitable distribution of food to low-income households.

The decision of 'How to produce' is solved by farm managers adopting capital-intensive methods to achieve cost efficiency. However, the state-imposed price ceiling suppresses the market clearing mechanism for 'For whom to produce'. Because the price is capped below equilibrium, suppliers produce less while consumer demand expands, creating a structural shortage. Consequently, low-income households cannot reliably obtain food, demonstrating how price controls distort resource allocation despite private technological efficiency.

Step-by-Step Solution

1

Analyze the resolution of 'How to produce'

Producers choose capital-intensive automated techniques to optimize technical efficiency and reduce unit costs in response to relative factor prices.

The basic problem of 'How to produce' concerns selecting the combination of factors and production technology that minimizes cost.

2

Analyze the policy impact on 'For whom to produce'

Setting a legally mandated price ceiling below equilibrium creates a shortage (

Q_d > Q_s

) because lower prices reduce supplier revenue while boosting consumer demand.

'For whom to produce' depends on purchasing power in market economies; intervention via price ceiling disrupts price rationing without supplying sufficient output.

3

Synthesize the interaction of both mechanisms on resource allocation

Private efficiency gains from technology are undermined by supply deficits caused by the price control, leaving low-income consumers unable to acquire the scarce commodity despite nominal price protection.

Resource allocation becomes sub-optimal when price controls prevent market clearing and create non-price rationing mechanisms like queues or black markets.

An entrepreneur in Port Harcourt has sufficient capital to establish either a palm oil refinery or a commercial fish farm. If he chooses to invest in the palm oil refinery, what is the opportunity cost of his decision?

The expected financial profit generated from operating the palm oil refinery

The return and benefits foregone from not establishing the commercial fish farm

The total amount of money spent on purchasing equipment for the palm oil refinery

The combined operational costs of both the palm oil refinery and the fish farm

Show answer & explanation

Answer: The return and benefits foregone from not establishing the commercial fish farm

Answer

The return and benefits foregone from not establishing the commercial fish farm.

Opportunity cost (or real cost) refers to the next best alternative foregone when an economic decision is made. By allocating capital to the palm oil refinery, the entrepreneur sacrifices the potential returns from the commercial fish farm.

Step-by-Step Solution

1

Identify the choices available to the decision-maker.

The entrepreneur must choose between Option 1 (palm oil refinery) and Option 2 (commercial fish farm).

Opportunity cost arises only when scarcity forces a choice between alternative courses of action.

2

Identify the selected choice and the sacrificed alternative.

The selected choice is the palm oil refinery, leaving the commercial fish farm as the sacrificed alternative.

Opportunity cost is measured by the value of the next best alternative that is given up.

3

Formulate the definition of opportunity cost for this context.

The opportunity cost is the yield or profit foregone from the commercial fish farm.

Real cost in economics is expressed in terms of goods, services, or benefits foregone, not monetary expenditure.

Question 9557Question →

When a government levies a fixed monetary amount of $\text{N}50$ on each physical unit of a commodity sold, regardless of its market price, what type of tax is this?

An ad valorem tax

A specific tax

A progressive tax

A direct tax

Show answer & explanation

Answer: A specific tax

Answer

A specific tax

A specific tax is defined as a fixed amount of tax levied per physical unit of a commodity sold (such as

\text{N}50

per unit or per litre), irrespective of the item's unit price.

Step-by-Step Solution

1

Identify the basis on which the tax is charged in the given scenario.

The tax is charged as a fixed sum of money (

\text{N}50

) per physical unit of the commodity.

Indirect taxes on commodities can be levied either according to physical quantity or according to monetary value.

2

Determine the economic term for a per-unit tax.

A fixed charge per physical unit is classified as a specific tax.

This distinguishes it from an ad valorem tax, which is expressed as a percentage of the item's selling price.

Question 9558Question →

Which Nigerian government economic policy was primarily designed to transfer ownership, control, and equity participation of foreign-dominated business enterprises to indigenous citizens?

Indigenization

Privatization

Commercialization

Export promotion

Show answer & explanation

Answer: Indigenization

Answer

Indigenization is the economic policy aimed at transferring ownership, management, and control of foreign enterprises to indigenous citizens.

Indigenization policy (promulgated through the Nigerian Enterprises Promotion Decrees) aimed to foster indigenous participation and economic sovereignty by transferring equity interest and operational control of foreign-owned enterprises to Nigerian citizens.

Step-by-Step Solution

1

Identify the primary objective specified in the question stem

The policy targets transferring foreign equity ownership and business control to local citizens.

This policy was enacted in Nigeria during the 1970s to reduce foreign dominance in key commercial sectors.

2

Distinguish between Nigerian public enterprise and industrial reform policies

Indigenization regulates foreign enterprise ownership, whereas privatization transfers government assets to private hands, and commercialization forces government entities to operate for profit.

Matching the definition to the economic term confirms that Indigenization is the correct policy.

Question 9559Question →

Under the framework established by the Technical Committee on Privatisation and Commercialisation (TCPC) in Nigeria, a state-owned enterprise undergoes reform such that the federal government retains 100% of its equity ownership, completely withdraws all operating treasury subsidies, and grants the enterprise total autonomy to determine commercial tariffs and cover all capital and operating costs. Which reform classification precisely describes this public enterprise restructuring?

Full commercialization

Partial commercialization

Partial privatization

Full privatization

Show answer & explanation

Answer: Full commercialization

Answer

Full commercialization is the reform policy where the government retains total equity ownership while making the enterprise financially self-sufficient without operational or capital subsidies.

Full commercialization occurs when a public enterprise is restructured to operate as a strictly profit-making business without receiving any government subventions or operational/capital subsidies, while retaining 100% state equity ownership.

Step-by-Step Solution

1

Analyze equity ownership state

The federal government retains 100% equity ownership, ruling out all forms of privatization.

Privatization by definition requires transferring equity ownership from public to private hands.

2

Analyze financial autonomy and subsidy status

The enterprise receives zero operating subsidies and must cover both operational and capital expenditure via market-determined tariffs.

Complete financial self-sufficiency with total subsidy elimination distinguishes full commercialization from partial commercialization.

3

Match findings to public enterprise reform policy classifications

Full commercialization correctly describes 100% public ownership combined with full operational independence and financial self-sustenance.

This matches the exact classification set by the TCPC guidelines under Nigerian economic reform policies.

A poultry farm operating in the short run incurs a Total Fixed Cost ( $\text{TFC}$ ) of $\text{₦}5,000$ . When output increases from $40$ crates to $50$ crates of eggs, the farm's Average Variable Cost ( $\text{AVC}$ ) rises from $\text{₦}150$ per crate to $\text{��}180$ per crate. What is the Marginal Cost ( $\text{MC}$ ) per crate for these additional $10$ crates?

\text{₦}30

per crate

\text{₦}300

per crate

\text{₦}800

per crate

\text{₦}1,400

per crate

Show answer & explanation

Answer: $\text{₦}300$ per crate

Answer

The Marginal Cost (

\text{MC}

) per crate for the additional

10

crates is

\text{₦}300

.

To find Marginal Cost (

\text{MC}

), calculate the change in total cost resulting from producing the additional

10

crates. At

40

crates,

\text{TVC} = 40 \times \text{₦}150 = \text{₦}6,000

. At

50

crates,

\text{TVC} = 50 \times \text{₦}180 = \text{₦}9,000

. The change in total variable cost is

\text{₦}9,000 - \text{₦}6,000 = \text{₦}3,000

. Dividing this by the output increase of

10

crates gives

\text{MC} = \text{₦}300

per crate.

Step-by-Step Solution

1

Calculate Total Variable Cost (

\text{TVC}

) at output level

Q_1 = 40

and

Q_2 = 50

.

\text{TVC}_1 = 40 \times \text{₦}150 = \text{₦}6,000

;

\text{TVC}_2 = 50 \times \text{₦}180 = \text{₦}9,000

.

Total Variable Cost is derived by multiplying total output quantity (

Q

) by Average Variable Cost (

\text{AVC}

).

2

Determine the change in Total Variable Cost (

\Delta \text{TVC}

).

\Delta \text{TVC} = \text{₦}9,000 - \text{₦}6,000 = \text{₦}3,000

.

Because Total Fixed Cost (

\text{TFC}

) is constant in the short run (

\Delta \text{TFC} = 0

), the change in Total Cost (

\Delta \text{TC}

) equals the change in Total Variable Cost (

\Delta \text{TVC}

).

3

Compute Marginal Cost (

\text{MC}

) by dividing

\Delta \text{TC}

by the change in output (

\Delta Q

).

\text{MC} = \frac{\text{₦}3,000}{50 - 40} = \frac{\text{₦}3,000}{10} = \text{₦}300

per crate.

Marginal cost is defined as the additional cost incurred from producing one extra unit of output:

\text{MC} = \frac{\Delta \text{TC}}{\Delta Q}

.
