A-Level Economics H2 Quiz - Microeconomics (Answer Key)

Total Marks: 40
Note: Syllabus-first generated content from LLM-inferred templates. Not past-year exam derived.

---

Section A (Q1–Q10, 2 marks each)

Q1. [2 marks]
Signalling function: Prices act as signals to producers and consumers. A rising price signals scarcity and encourages producers to increase supply while telling consumers to reduce demand.
Teaching note: The price mechanism coordinates via price changes without central planning.

Q2. [2 marks]
Any one: consumer income, tastes/preferences, price of related goods (substitutes/complements), population size, expectations.
Common mistake: Stating "price of the good" – that causes movement, not shift.

Q3. [2 marks]
Consumer surplus is the difference between what consumers are willing to pay and what they actually pay.

Q4. [2 marks]
Inferior good (since $YED < 0$, demand falls when income rises).

Q5. [2 marks]
Maximum price (price ceiling) or minimum price (price floor).

Q6. [2 marks]
$PED = 0$ (quantity demanded does not change with price).

Q7. [2 marks]
Incentive function: Higher prices incentivise producers to supply more and consumers to buy less; lower prices do opposite.

Q8. [2 marks]
Supply curve shifts left (decrease in supply) due to higher cost per unit.

Q9. [2 marks]
$XED = \frac{\% \Delta Q_d^A}{\% \Delta P^B}$. For substitutes, $XED > 0$.

Q10. [2 marks]
Profit maximisation occurs where $MR = MC$ and $MC$ is rising.

---

Section B (Q11–Q16)

Q11. [5 marks]
(a) [2] For a normal good, higher income increases demand at each price → demand curve shifts right.
(b) [3] Diagram shows D1→D2 right, equilibrium price rises P1→P2, quantity Q1→Q2. See Q11-fig1: labels P, Q, D1, S, D2, E1, E2.

Q12. [5 marks]
(a) [3] $P = 20 - 0.5Q$ → at $P=12$, $Q=16$. $\frac{dQ}{dP} = -2$. $PED = (-2) \times (12/16) = -1.5$.
(b) [2] $|PED|>1$ (elastic) → decreasing price increases total revenue.

Q13. [5 marks]
(a) [3] Subsidy lowers cost → S shifts right → price falls, quantity rises (Q13-fig1).
(b) [2] Consumers gain CS; producers gain PS (or receive higher effective price).

Q14. [4 marks]

1. Movement along: caused by price change of the good itself; shift: caused by non-price determinants.
2. Movement: changes quantity demanded only; shift: changes demand at all prices.

Q15. [4 marks]
(a) [1] $PES = \frac{\% \Delta Q_s}{\% \Delta P}$.
(b) [3] Elastic, because quick output response means quantity supplied reacts strongly to price.

Q16. [5 marks]
[5] May benefit consumers via lower price, but causes shortage, black market, reduced quality. Not necessarily benefit all. Mark descriptors: identify effect (2), evaluate trade-off (3).

---

Section C (Q17–Q20)

Q17. [5 marks]
(a) [3] EV demand ↑ → derived demand for lithium ↑ → lithium price & quantity ↑ (Q17-fig1).
(b) [2] Capacity constraints / time to open mines (inelastic short-run supply).

Q18. [5 marks]
(a) [3] Quota reduces supply → domestic price ↑, quantity ↓ (Q18-fig1).
(b) [2] Consumers face higher prices, less choice.

Q19. [4 marks]
[4] Consumer choice helps but market failure (externalities) limits impact; info asymmetry and cost barriers. Evaluation needed.

Q20. [5 marks]
(a) [2] Non-price competition (advertising/branding).
(b) [3] Advertising shifts D right and steepens → higher P and Q (Q20-fig1).
