19. With reference to the extract below, use a diagram to explain how an increase in demand for electric vehicles affects the market for lithium.

Extract: Global sales of electric vehicles rose by 35% in 2025, raising demand for battery materials.

Version 3 of 5 — Answer Key

Total Marks: 60

Section A: Market Mechanism and Elasticity (21 marks)

Q1 [2 marks]
Signalling function: Price acts as a signal to producers and consumers. A rising price signals scarcity and encourages producers to increase supply while signalling consumers to reduce demand; a falling price signals surplus and encourages consumers to buy more and producers to supply less.
Marking: 1 mark for definition of signalling, 1 mark for example of price change effect.

Q2 [2 marks]
(a) Shift of the demand curve (income is a non-price determinant).
(b) Movement along the demand curve (own price change).
1 mark each.

Q3 [2 marks]
PED measures responsiveness of quantity demanded to a change in price. Formula:
$\text{PED} = \frac{\% \Delta Q_d}{\% \Delta P} = \frac{\Delta Q_d / Q_1}{\Delta P / P_1}$
1 mark definition, 1 mark formula.

Q4 [3 marks]
$\% \Delta P = \frac{12-10}{10} \times 100 = +20\%$
$\% \Delta Q_d = \frac{80-100}{100} \times 100 = -20\%$
$\text{PED} = \frac{-20\%}{+20\%} = -1.0$ (elasticity of unity)
1 mark for each calculation step, 1 mark for final value. Note: ignore negative sign for magnitude but show it.

Q5 [2 marks]
YED = +2.5 → normal good (positive YED). Since >1, it is a luxury good (income elastic).
1 mark normal, 1 mark luxury.

Q6 [2 marks]
XED = –1.2 indicates X and Y are complements (negative cross elasticity). A 1% rise in price of Y leads to 1.2% fall in demand for X.
1 mark complement, 1 mark interpretation.

Q7 [3 marks]
Diagram: subsidy shifts S to S1 right; P falls $8→$6, Q rises 100→130. Consumer expenditure = P×Q = 8×100 = 800 initially; after = 6×130 = 780. Expenditure falls slightly despite higher quantity because price drop dominates.
1 mark diagram correct, 1 mark calculation, 1 mark explanation of net effect.

Section B: Government Intervention and Market Failure (18 marks)

Q8 [2 marks]
Maximum price: legally set ceiling below equilibrium to protect consumers. Minimum price: legally set floor above equilibrium to protect producers.
1 mark each.

Q9 [2 marks]
Max price below equilibrium → quantity demanded exceeds quantity supplied → shortage (excess demand). May lead to queues or black market.
1 mark shortage, 1 mark consequence.

Q10 [4 marks]
Diagram: tax shifts S left to S_tax; Q falls 100→80; consumers pay 11, producers get 9; DWL triangle shows lost mutual gains.
2 marks diagram, 2 marks explanation of DWL as efficiency loss.

Q11 [2 marks]
Negative externality (e.g. pollution) → private cost < social cost → overproduction relative to socially optimal level.
1 mark externality type, 1 mark effect.

Q12 [4 marks]
Tax corrects negative externality by internalising external cost; subsidy is for positive externalities. Subsidy on negative externality may increase output further, worsening failure. However subsidy to adopt clean tech can reduce externality at source. Evaluation: not always more effective; depends on externality type and behaviour.
2 marks analysis, 2 marks evaluation.

Q13 [4 marks]
At world price, domestic demand 120 > domestic supply + quota 50 → shortage. Domestic price rises above world price to equate domestic supply + 50 import to demand. Quantity traded = domestic supply + 50.
2 marks reasoning, 2 marks price/quantity outcome.

Section C: Firms and Decisions (21 marks)

Q14 [1 mark]
Profit maximisation where MR = MC and MC rising.

Q15 [4 marks]
TR = 100Q – 2Q² → MR = d(TR)/dQ = 100 – 4Q
TC = 20Q + 50 → MC = d(TC)/dQ = 20
Set MR = MC: 100 – 4Q = 20 → 4Q = 80 → Q = 20.
1 mark MR, 1 mark MC, 2 marks solving Q.

Q16 [2 marks]
Managers may satisfice due to separation of ownership and control (principal-agent), aiming for adequate profit to keep shareholders and workers content rather than max.
1 mark reason, 1 mark elaboration.

Q17 [2 marks]
Advertising, branding, product differentiation, customer service. (Any two)
1 mark each.

Q18 [5 marks]
Merger may reduce competition → higher price, lower CS. But efficiencies could lower cost and price; network effects may improve service; if market contestable, discipline remains. Evaluate: not necessarily reduces CS if gains passed to consumers.
2 marks analysis, 3 marks evaluation with balanced judgment.

Q19 [3 marks]
EV demand rise → derived demand for lithium rises → lithium P and Q increase. Diagram shows both shifts.
1 mark diagram, 2 marks explanation of derived demand chain.

Q20 [4 marks]
Price discrimination increases revenue if segments have different PED and arbitrage prevented. But may need complex segmentation; alternative is volume expansion. Not always best; depends on info and elasticity gap.
2 marks analysis, 2 marks evaluation.
