Question 9721Question

If a consumer spends a fixed money income exclusively on Good XX (plotted on the horizontal axis) and Good YY (plotted on the vertical axis), a simultaneous per-unit tax on Good XX and per-unit subsidy on Good YY will cause the budget line to pivot inward along the horizontal axis, pivot outward along the vertical axis, and become steeper.

Show answer & explanation

Answer: True

Answer

The statement is True. Increasing the price of the horizontal good while decreasing the price of the vertical good reduces the horizontal intercept, expands the vertical intercept, and increases the magnitude of the slope (PX/PYP_X / P_Y), making the budget line steeper.
The statement is correct because taxing Good XX raises PXP_X while subsidizing Good YY lowers PYP_Y. The absolute slope of the budget line equals PX/PYP_X / P_Y. A higher numerator (PXP_X) and a lower denominator (PYP_Y) increase the value of PX/PYP_X / P_Y, resulting in a steeper budget line anchored to a smaller horizontal intercept and a larger vertical intercept.

Step-by-Step Solution

1
Analyze the impact on the horizontal intercept (I/PXI / P_X).
Taxing Good XX increases PXP_X, which decreases I/PXI / P_X and pivots the horizontal intercept inward toward the origin.
The horizontal intercept represents total income divided by the price of Good XX.
2
Analyze the impact on the vertical intercept (I/PYI / P_Y).
Subsidizing Good YY decreases PYP_Y, which increases I/PYI / P_Y and pivots the vertical intercept outward away from the origin.
The vertical intercept represents total income divided by the price of Good YY.
3
Determine the change in the budget line slope magnitude (PX/PYP_X / P_Y).
With PXP_X rising and PYP_Y falling, the price ratio PX/PYP_X / P_Y increases, causing the budget line to become steeper.
The slope of the budget line measures the rate at which Good YY must be given up for Good XX in the market.

Question 9722Question

A household's maximum willingness to pay for successive kegs of palm oil is given in the table below:

Unit (Keg)Maximum Willingness to Pay (₦)
1st500
2nd450
3rd400
4th350
5th300

If the market price per keg is ₦350, what is the total consumer surplus derived by the household?

Show answer & explanation

Answer: ₦300

Answer

The total consumer surplus derived by the household is ₦300.
The correct answer is ₦300. At a market price of ₦350, the household consumes 4 kegs of palm oil because willingness to pay equals price at the 4th unit. Total willingness to pay for 4 kegs is ₦500 + ₦450 + ₦400 + ₦350 = ₦1,700. The actual expenditure is 4 × ₦350 = ₦1,400. Thus, consumer surplus = ₦1,700 - ₦1,400 = ₦300.

Step-by-Step Solution

1
Determine the quantity of palm oil kegs the household will purchase at the market price of ₦350.
The consumer will buy up to the 4th keg because for the 4th keg, willingness to pay (���350) equals market price (₦350). The 5th keg will not be purchased because willingness to pay (₦300) is less than market price.
A rational consumer purchases additional units as long as willingness to pay is greater than or equal to market price.
2
Calculate the total willingness to pay (total monetary utility) for the 4 purchased kegs.
Total Willingness to Pay = ₦500 + ₦450 + ₦400 + ₦350 = ₦1,700.
Total willingness to pay is the sum of maximum prices the consumer is prepared to pay for each consumed unit.
3
Calculate the actual total expenditure incurred by buying 4 kegs at ₦350 each.
Total Expenditure = 4 units × ₦350 = ₦1,400.
Actual expenditure is calculated as total quantity purchased multiplied by prevailing market price.
4
Subtract actual total expenditure from total willingness to pay to obtain consumer surplus.
Consumer Surplus = ₦1,700 - ₦1,400 = ₦300.
Consumer surplus measures the net economic benefit or gain derived by consumers when paying less than their maximum willingness to pay.

Question 9724Question

A specific tax of 15\text{₦}15 per unit is imposed on a luxury commodity. Prior to the imposition of the tax, the equilibrium market price was 100\text{₦}100 per unit. Following the tax, the market price paid by consumers increases to 109\text{₦}109 per unit. What is the amount of the unit tax borne by the producer in Naira (\text{₦})?

Show answer & explanation

Answer: 6

Answer

The producer bears ₦6 of the ₦15 per unit tax.
Tax incidence refers to how the ultimate economic burden of a tax is divided between buyers and sellers. When a unit tax of 15\text{₦}15 raises the consumer price from 100\text{₦}100 to 109\text{₦}109, consumers bear 9\text{₦}9 of the tax burden per unit. The producer receives 10915=94\text{₦}109 - \text{₦}15 = \text{₦}94 per unit after paying the tax to the government. The net price reduction for the producer is 10094=6\text{₦}100 - \text{₦}94 = \text{₦}6, which represents the producer's incidence of the tax.

Step-by-Step Solution

1
Calculate the consumer's share of the tax incidence per unit.
Consumer tax share = 109100=9\text{₦}109 - \text{₦}100 = \text{₦}9.
The portion of an indirect tax passed forward to consumers equals the increase in the market price paid by buyers.
2
Calculate the producer's share of the tax incidence per unit.
Producer tax share = 159=6\text{₦}15 - \text{₦}9 = \text{₦}6.
The total per-unit tax is distributed between the consumer and the producer. Deducting the consumer's share from the total tax leaves the producer's share.

Question 9725Question

A concrete block manufacturing factory operates in the short run with fixed molding machinery and variable labor (LL). When 44 workers are employed, the average product of labor (APLAP_L) is 3030 blocks per worker. When a 5th5\text{th} worker is hired, the total product of labor (TPLTP_L) increases to 145145 blocks. What is the marginal product (MPLMP_L) of the 5th5\text{th} worker?

Show answer & explanation

Answer: 25

Answer

The marginal product of the 5th worker is 25 blocks.
To find the marginal product of the 5th worker, first determine total product for 4 workers by multiplying 4 workers by their average product of 30 blocks, giving 120 blocks. The marginal product of the 5th worker is the difference between the total product with 5 workers (145 blocks) and total product with 4 workers (120 blocks), which equals 25 blocks.

Step-by-Step Solution

1
Calculate the total output produced by 4 workers using the average product formula
Total Product for 4 workers (TP4TP_4) = 4×30=1204 \times 30 = 120 blocks.
Average Product (APAP) equals Total Product (TPTP) divided by Labor (LL), so TP=L×APTP = L \times AP.
2
Calculate the change in total output resulting from employing the 5th worker
Marginal Product (MP5MP_5) = 145120=25145 - 120 = 25 blocks.
Marginal Product is the addition to total output when one additional unit of variable input is employed (MPL=ΔTP/ΔLMP_L = \Delta TP / \Delta L).

Question 9726Question

A government issues 91-day Treasury bills to cover an immediate deficiency in recurrent expenditure, while concurrently making systematic annual deposits into a dedicated reserve to redeem a 20-year bond issue at maturity. How are these two public debt instruments classified respectively?

Show answer & explanation

Answer: Floating debt and funded debt

Answer

The short-term Treasury bill obligation is classified as floating debt, while the long-term bond issue backed by a dedicated redemption fund is classified as funded debt.
Public debt is categorized by tenure and repayment arrangements. Floating (unfunded) debt consists of short-term obligations like Treasury bills issued to meet temporary revenue gaps. Funded debt comprises long-term obligations for which a dedicated fund (such as a sinking fund) is systematically created to pay off the principal upon maturity. Therefore, the short-term Treasury bill is floating debt and the 20-year bond with annual redemption deposits is funded debt.

Step-by-Step Solution

1
Analyze the first debt instrument (91-day Treasury bills used for short-term deficit spending).
Identify that short-term debt maturing within a year without a permanent provision for redemption is floating (unfunded) debt.
Floating debt provides temporary liquidity to bridge budget gaps.
2
Analyze the second debt instrument (20-year bond backed by systematic annual deposits into a dedicated reserve).
Identify that long-term debt tied to a dedicated redemption fund (sinking fund) is funded debt.
Funded debt has a long duration and explicit financial mechanisms established for its gradual debt retirement.
3
Match both classifications sequentially.
The correct classification pair is floating debt and funded debt.
The sequence must reflect the short-term instrument first and the long-term sinking fund instrument second.

Question 9729Question

In a regional market for poultry feed, the daily quantity demanded is expressed as Qd=48012PQ_d = 480 - 12P and the daily quantity supplied is expressed as Qs=120+18PQ_s = -120 + 18P, where PP represents the price per bag in hundreds of Naira and QQ represents quantity in bags. What is the market equilibrium price per bag in hundreds of Naira?

Show answer & explanation

Answer: 20

Answer

The market equilibrium price is 20 (in hundreds of Naira).
Equilibrium price is established when quantity demanded equals quantity supplied (Qd=QsQ_d = Q_s). Setting 48012P=120+18P480 - 12P = -120 + 18P yields 30P=60030P = 600, resulting in an equilibrium price of 20 (in hundreds of Naira).

Step-by-Step Solution

1
Equate the demand and supply equations to find market equilibrium.
48012P=120+18P480 - 12P = -120 + 18P
Market equilibrium occurs at the price level where the quantity buyers wish to purchase equals the quantity sellers wish to supply.
2
Rearrange the equation by grouping constant terms on one side and price variables on the other.
30P=60030P = 600
Adding 12P12P to both sides eliminates 12P-12P on the left, and adding 120120 to both sides eliminates 120-120 on the right.
3
Divide the total value by the coefficient of price to determine equilibrium price.
P=20P = 20
Dividing 600600 by 3030 isolates PP to give the equilibrium price.

Question 9730Question

A country recorded an Income Terms of Trade index of 144144 and an export volume index of 120120 relative to the base year index of 100100. If the country's import price index stood at 125125 during the same period, what was its export price index?

Show answer & explanation

Answer: 150

Answer

The export price index is 150.
The Income Terms of Trade (ITTITT) formula is ITT=(PxPm)×QxITT = \left(\frac{P_x}{P_m}\right) \times Q_x. Substituting the given values (ITT=144ITT = 144, Qx=120Q_x = 120, Pm=125P_m = 125) gives 144=(Px125)×120144 = \left(\frac{P_x}{125}\right) \times 120. Rearranging the equation to solve for the export price index yields Px=144×125120=150P_x = \frac{144 \times 125}{120} = 150.

Step-by-Step Solution

1
Identify the relationship between Income Terms of Trade, price indices, and volume index
ITT=(PxPm)×QxITT = \left(\frac{P_x}{P_m}\right) \times Q_x
Income Terms of Trade measures a nation's capacity to import based on export earnings, combining the net barter terms of trade with export quantity.
2
Substitute given values into the formula
144=(Px125)×120144 = \left(\frac{P_x}{125}\right) \times 120
The given values are ITT=144ITT = 144, Qx=120Q_x = 120, and Pm=125P_m = 125.
3
Isolate the unknown variable PxP_x
Px=144×125120=150P_x = \frac{144 \times 125}{120} = 150
Multiplying both sides by 125125 and dividing by 120120 isolates PxP_x to determine the export price index.

Answer

Market-oriented location matches with commercial bakeries in Lagos; Raw material-oriented location matches with cement factory near limestone deposits at Ewekoro; Localization of industry matches with concentration of leather tanneries in Kano; Government policy intervention matches with Calabar Free Trade Zone tax incentives.
Market-oriented industries locate near consumers to handle perishable or weight-gaining outputs. Raw material-oriented industries locate near inputs when handling weight-losing materials like limestone. Localization involves the concentration of multiple firms of the same industry in one geographical area, such as Kano's leather industry. Government intervention uses industrial estates and tax incentives to influence location.

Step-by-Step Solution

1
Analyze market-oriented firm location factors.
Perishable goods such as fresh bread gain value and perish quickly, requiring proximity to urban consumer centers.
Siting near markets reduces final product distribution costs and spoilage risks.
2
Analyze raw material-oriented firm location factors.
Bulky raw inputs like limestone lose significant weight during processing into cement.
Transporting raw inputs is more expensive than transporting processed outputs for weight-losing processes.
3

Question 9733Question

In a regional agricultural market, the total stock of money in circulation (MM) is ₦80,000 and the average price level (PP) per unit of output is ₦250. If the physical volume of transactions (TT) recorded during the period is 1,600 units, calculate the velocity of circulation (VV) of money.

Show answer & explanation

Answer: 5

Answer

The velocity of circulation of money (VV) is 5.
According to Irving Fisher's Quantity Theory of Money (MV=PTMV = PT), the total monetary flow in an economy (MVMV) equals the total nominal value of transactions (PTPT). Substituting M=80,000M = 80,000, P=250P = 250, and T=1,600T = 1,600 into the equation gives 80,000×V=400,00080,000 \times V = 400,000. Solving for VV yields V=5V = 5, meaning each unit of currency changed hands 5 times on average during the period.

Step-by-Step Solution

1
Identify the given parameters and select the appropriate formula
Money supply (MM) = ₦80,000, Price level (PP) = ₦250, Volume of transactions (TT) = 1,600. Use Fisher's Equation of Exchange: MV=PTMV = PT.
Irving Fisher's equation establishes that total money spending (MVMV) equals total value of goods and services traded (PTPT).
2
Substitute the numerical values into the equation
80,000×V=250×1,60080,000 \times V = 250 \times 1,600
Plugging the known quantitative values isolates VV as the single unknown variable.
3
Solve for the velocity of circulation (VV)
80,000×V=400,000    V=400,00080,000=580,000 \times V = 400,000 \implies V = \frac{400,000}{80,000} = 5
Dividing total monetary outlay (PTPT) by total money stock (MM) determines how many times a unit of currency changes hands on average.

Question 9735Question

In a financial year, a government collected 650 billion\text{₦}650\text{ billion} in tax revenue and 180 billion\text{₦}180\text{ billion} in non-tax revenue. During the same period, its recurrent expenditure was 520 billion\text{₦}520\text{ billion} and its capital expenditure was 460 billion\text{₦}460\text{ billion}. What is the government's budget deficit in billions of Naira (\text{₦})?

Show answer & explanation

Answer: 150

Answer

The government's budget deficit is 150 billion\text{₦}150\text{ billion}.
The budget deficit represents the excess of total expenditure over total revenue in a fiscal period. Adding tax revenue (650 billion\text{₦}650\text{ billion}) and non-tax revenue (180 billion\text{₦}180\text{ billion}) gives a total revenue of 830 billion\text{₦}830\text{ billion}. Adding recurrent expenditure (520 billion\text{₦}520\text{ billion}) and capital expenditure (460 billion\text{₦}460\text{ billion}) yields a total expenditure of 980 billion\text{₦}980\text{ billion}. The difference (980 billion830 billion\text{₦}980\text{ billion} - \text{₦}830\text{ billion}) results in a budget deficit of 150 billion\text{₦}150\text{ billion}.

Step-by-Step Solution

1
Calculate Total Revenue
Total Revenue = 830 billion\text{₦}830\text{ billion}
Total revenue is the sum of tax revenue and non-tax revenue: 650 billion+180 billion=830 billion\text{₦}650\text{ billion} + \text{₦}180\text{ billion} = \text{₦}830\text{ billion}.
2
Calculate Total Expenditure
Total Expenditure = 980 billion\text{₦}980\text{ billion}
Total expenditure is the sum of recurrent expenditure and capital expenditure: 520 billion+460 billion=980 billion\text{₦}520\text{ billion} + \text{₦}460\text{ billion} = \text{₦}980\text{ billion}.
3
Calculate Budget Deficit
Budget Deficit = 150 billion\text{₦}150\text{ billion}
A budget deficit occurs when total expenditure exceeds total revenue. Deficit = Total Expenditure - Total Revenue = 980 billion830 billion=150 billion\text{₦}980\text{ billion} - \text{₦}830\text{ billion} = \text{₦}150\text{ billion}.

Matches

Show answer & explanation

Answer

The correct matches pair: 1) Long-Run Average Total Cost Curve (Envelope Curve) with the locus of points forming a lower boundary wrapper around short-run average total cost curves when all inputs are variable; 2) Minimum Efficient Scale (MES) with the lowest output level at which a firm fully exploits scale economies and minimizes long-run average total cost; 3) Managerial Diseconomies of Scale with the upward-sloping region of the long-run average cost curve stemming from administrative friction and coordination breakdown; and 4) External Economies of Scale with cost advantages accruing to a firm due to industry-wide expansion, such as localized specialized labor pools and infrastructure.
Each concept correctly maps to its theoretical foundation: the Envelope Curve envelops short-run cost curves; Minimum Efficient Scale marks the point of lowest unit cost; Managerial Diseconomies of Scale generate rising long-run costs due to bureaucracy; and External Economies of Scale lower unit costs through industry-wide technological or infrastructural growth.

Step-by-Step Solution

1
Analyze the structural construction of the Long-Run Average Total Cost (LRATC) curve.
Identify that LRATC acts as an envelope wrapping around short-run average cost curves because firms can adjust all production inputs in the long run.
In the long run, no factor of production is fixed, enabling the selection of the optimal plant size for any output.
2
Determine the economic significance of Minimum Efficient Scale (MES).
Identify MES as the threshold output level where economies of scale are exhausted and long-run unit costs reach their minimum.
Achieving MES is necessary for a firm to operate at peak long-run productive efficiency.
3
Examine the root cause of upward-sloping LRATC.
Associate rising long-run average costs with managerial inefficiencies and administrative bottlenecks in over-expanded firms.
As organizational scale expands past optimal boundaries, managerial coordination problems create internal diseconomies of scale.
4
Distinguish internal scale effects from external industry-wide effects.
Connect cost advantages derived from shared industry infrastructure and specialized labor to external economies of scale.
External economies lower the cost curves of all firms within an industry independently of an individual firm's internal scale decisions.

Question 9739Question

Which factor explains why fluctuations in international crude oil prices frequently destabilize national development plans in Nigeria?

Show answer & explanation

Answer: The high reliance on petroleum revenues to finance planned capital expenditure

Answer

The high reliance on petroleum revenues to finance planned capital expenditure
A major financial challenge in Nigerian economic planning is over-reliance on crude oil export revenues. Because development plans rely on oil proceeds to fund major capital projects, sudden drops in global oil prices create severe revenue shortfalls, leading to plan distortions and abandoned infrastructure projects.

Step-by-Step Solution

1
Identify the primary source of government revenue in Nigeria's economic planning framework
Crude oil exports provide the majority of government revenue and foreign exchange earnings.
Understanding revenue composition is essential for evaluating budget stability during plan implementation.
2
Analyze how external price shocks impact designated capital projects
When international oil prices drop below benchmark projections, budget deficits emerge and funding for planned projects is curtailed.
Price volatility directly disrupts the revenue inflows required to fulfill planned targets.

Question 9740Question

At the beginning of a given trading period, the nominal exchange rate between the Nigerian Naira (NGN\text{NGN}) and the US Dollar (USD\text{USD}) is $1=NGN 500\$1 = \text{NGN } 500. During the period, Nigeria records an annual inflation rate of 26%26\%, whereas the United States records an annual inflation rate of 5%5\%. According to the relative Purchasing Power Parity (PPP) theory of exchange rate determination, what is the new equilibrium nominal exchange rate in NGN\text{NGN} per USD\text{USD}?

Show answer & explanation

Answer: 600

Answer

The new equilibrium nominal exchange rate is 600 NGN per USD.
Under relative Purchasing Power Parity, an inflation differential between two trading partners leads to a proportional depreciation of the currency with higher inflation. Dividing the domestic price index factor (1.26) by the foreign price index factor (1.05) yields an adjustment multiplier of 1.20. Multiplying the initial rate of 500 NGN/USD by 1.20 gives 600 NGN/USD.

Step-by-Step Solution

1
Identify the relative Purchasing Power Parity (PPP) formula for exchange rate adjustment based on inflation differentials.
Formula: E1=E0×1+idomestic1+iforeignE_1 = E_0 \times \frac{1 + i_{\text{domestic}}}{1 + i_{\text{foreign}}}
Relative PPP states that exchange rates change to offset differences in inflation rates between two nations.
2
Substitute the initial rate (500), domestic inflation (0.26), and foreign inflation (0.05) into the equation.
E1=500×1.261.05E_1 = 500 \times \frac{1.26}{1.05}
This adjusts the currency valuation proportionally to the change in relative purchasing power.
3
Perform the division and multiplication.
E1=500×1.20=600E_1 = 500 \times 1.20 = 600
Evaluating the expression yields the depreciated exchange rate for the domestic currency.
