Question 2 View Details
In a certain region the market for wheat is described by the linear demand and supply equations: Qd = 500 000 – 2 000 P Qs = –100 000 + 3 000 P where Q is the quantity of wheat in kilograms and P is the price per kilogram in naira.
Question Parts
(a)
Determine the equilibrium price and quantity before any government intervention.
(b)
The government imposes a specific tax of ₦20 per kilogram on wheat producers. Show the new supply equation and calculate the new equilibrium consumer price, producer price and quantity exchanged.
(c)
Using your results from part (b), compute the dead‑weight loss (DWL) caused by the tax. Show the formula used and give the numerical value in naira.

Question 3 View Details
A small electronics retailer sells a particular model of headphones. In January the price was ₦12,000 and 150 units were sold. In February the price was increased to ₦14,000 and sales fell to 120 units.
Question Parts
(a)
Calculate the price elasticity of demand between January and February using the midpoint (arc) method. Show all steps.
(b)
Interpret the calculated elasticity. State whether demand is elastic, inelastic or unit‑elastic and explain what this implies for total revenue when price rises.
(c)
Based on your analysis, advise the retailer whether to increase or decrease the price if the aim is to maximise total revenue. Justify your recommendation using the elasticity concept.

Question 4 View Details
A furniture manufacturer produces wooden chairs. The table below shows the amount of labour employed (L, in worker‑hours) and the corresponding total product of labour (TP, number of chairs produced) and variable cost (VC, in ₦) for a single day.
Question Parts
(a)
Calculate the average product of labour (AP) and the marginal product of labour (MP) for each level of labour from 1 to 5 worker‑hours. Show your workings in a table.
(b)
Using the data, compute the marginal cost (MC) of producing each additional chair between successive output levels. Present the MC values in a table.
(c)
Identify the range of labour input over which diminishing marginal returns set in. Explain how this change is reflected in the behaviour of marginal cost.
(d)
Discuss, using the TP‑L relationship, whether the firm is experiencing increasing, constant or decreasing returns to scale over the observed range. Justify your answer.

Question 5 View Details
A manufacturing firm produces a single product. Its total cost (TC) in thousands of naira for producing Q thousand units is given by TC = 0.5Q² + 20Q + 150. The market price of the product is constant at ₦30 per unit, so total revenue (TR) = 30Q (in thousands of naira).
Question Parts
(a)
Derive the expressions for average cost (AC) and marginal cost (MC).
(b)
Using the profit‑maximising rule, determine the output level (Q*) that maximises profit and calculate the maximum profit (in thousands of naira).
(c)
Discuss the short‑run shutdown condition for this firm and explain whether the firm should continue operating in the short run at the output found in part (b).

Question 6 View Details
Consider a market for a homogeneous good where the demand curve is P = 100 – 2Q (P in naira, Q in thousand units). The firm's total cost function is C = 20Q + 100 (in thousand naira).
Question Parts
(a)
State two characteristic features of a perfectly competitive market and two of a monopoly.
(b)
Assuming the firm operates as a price‑taking firm (perfect competition) and as a profit‑maximising monopoly, determine for each case: i. Equilibrium output (Q) and price (P). ii. Consumer surplus (CS) and producer surplus (PS) for perfect competition. iii. Monopoly profit, and the resulting dead‑weight loss (DWL) compared with perfect competition.
(c)
The government imposes a price ceiling of ₦40 per unit in this market (still a monopoly). Discuss the likely effects on output, welfare (CS, PS, DWL) and the incentives for the monopolist.

Question Parts
(a)
Calculate Gross Domestic Product (GDP) using the expenditure approach.
(b)
Calculate GDP using the income approach and comment on any difference between the two estimates.
(c)
Explain two limitations of GDP as a measure of national welfare.
(d)
Discuss how a large informal sector could affect the reliability of the GDP estimates for Country X.

Question 8 View Details
The Central Bank of Country Y operates a fractional‑reserve banking system. The required reserve ratio (RRR) is 10 %. The public holds currency equal to 30 % of total deposits (currency‑deposit ratio, c = 0.30).
Question Parts
(a)
Derive the formula for the money multiplier (M) in this economy, showing the role of the required reserve ratio and the currency‑deposit ratio.
(b)
Using the derived formula, calculate the theoretical maximum money multiplier for Country Y.
(c)
The Central Bank purchases government securities worth ₦200 million. Assuming banks lend out all excess reserves and the public does not change its currency‑deposit ratio, estimate the maximum possible increase in the money supply.
(d)
Evaluate two reasons why the actual increase in the money supply may be lower than the theoretical estimate obtained in part (c).

Question 9 View Details
The economy of Country X has recently experienced a rise in the general price level. The following information is provided: (i) The Consumer Price Index (CPI) increased from 120 to 138 over the past 12 months. (ii) The nominal interest rate set by the central bank is 12 % per annum. (iii) The exchange rate (local currency per US$) moved from 380 to 410 in the same period. (iv) The government’s fiscal deficit widened from 4 % to 6 % of GDP. Answer the questions below.
Question Parts
(a)
Calculate the average inflation rate over the period and discuss whether the inflation is more likely to be demand‑pull or cost‑push in nature.
(b)
Using the Fisher equation, estimate the expected real interest rate and evaluate whether the current nominal rate is adequate for controlling inflation.
(c)
Analyse how the observed exchange‑rate movement could affect inflationary pressures, considering both import‑price and export‑competitiveness channels.
(d)
Discuss two monetary‑policy measures and two fiscal‑policy measures that could be used to bring inflation back to the target range, and evaluate the likely short‑run trade‑offs of each measure.
