A-Level Economics H1 Quiz - Microeconomics: Answer Key

Total Marks: 40
Level: A-Level H1
Topic: Microeconomics
Note: Content generated from LLM-inferred templates (Stage 4/5) using syllabus-first design. Not claimed as past-year exam derived.

Section A Answers (Q1–8)

Q1. [2 marks]
Opportunity cost is the value of the next best alternative forgone when a choice is made.
Teaching note: Scarcity forces choices; whenever resources are used for one purpose, the benefit of the alternative use is lost. Mark: 1 for definition, 1 for "next best alternative" idea.

Q2. [2 marks]
Both Country A and Country B saw petrol prices rise from 2021 to 2023. Country A was consistently higher: $1.40→$ 1.80 (+28.6%) vs Country B $1.10→$ 1.40 (+27.3%).
Marking: 1 for both increased, 1 for comparative magnitude / Country A higher. Common mistake: stating only one country.

Q3. [2 marks]
Any two of: income, consumer preferences, population size, price of substitutes/complements, expectations of future prices.
1 mark each. Syllabus: non-price determinants of demand.

Q4. [2 marks]
The price mechanism signals where resources are needed: rising prices indicate shortage and attract producers; falling prices indicate surplus and signal exit.
1 for signalling scarcity/shortage, 1 for attracting resources.

Q5. [2 marks]
Quantity supplied rose from 50,000 in 2019 to 180,000 in 2023, an increasing trend at an accelerating rate.
1 for direction, 1 for rate/quantified. Image shows points 50→70→95→130→180.

Q6. [2 marks]
A negative externality is a cost imposed on third parties not involved in a transaction, where MSC > MPC.
1 for third-party cost, 1 for example or MPC/MSC note.

Q7. [1 mark]
Information failure (consumers underestimate health costs).
Accept "asymmetric info" not in syllabus; use information failure.

Q8. [2 marks]
Non-excludable and non-rivalrous.
1 each. Public goods: people cannot be excluded, one's use does not reduce another's.

Section B Answers (Q9–14)

Q9. [3 marks]
%ΔP = (1.50−1.20)/1.20 × 100 = +25%
%ΔQd = (720,000−800,000)/800,000 × 100 = −10%
PED = −10 / 25 = −0.4 (|0.4| inelastic)
1 for each step; final value.

Q10. [2 marks]
No. Since |PED|=0.4 < 1, demand is inelastic; raising price reduces Qd proportionally less, so total revenue (=P×Q) rises. But operator asked "should raise to increase revenue" — answer: yes if goal is revenue, but socially may reduce ridership.
Syllabus: inelastic demand → price↑ → TR↑. 2 marks for correct application.

Q11. [4 marks]
(1) Perishability: vegetables cannot be stored long, so supply cannot respond quickly to price rises [2]. (2) Growing time: biological cycle limits output adjustment in short run [2].
Any two valid reasons, 2 marks each.

Q12. [4 marks]
At P_max ( $1500) below P_e ($ 2000), Qd=14,000 > Qs=7,000, creating shortage of 7,000. Consumers gain lower price but many unsatisfied; producers supply less.
2 for diagram reading, 2 for shortage/expansion-contraction explanation.

Q13. [2 marks]
Consumer surplus = difference between what consumers pay and max willingness to pay. On diagram, area above price and below demand curve.
1 def, 1 location.

Q14. [4 marks]
Subsidy shifts S right (S1→S2), equilibrium price falls (P_e→P_s), quantity rises (Q_e→Q_s).
Diagram description: 2 marks; price/quantity effect: 2 marks.

Section C Answers (Q15–20)

Q15. [4 marks]
Tax shifts MPC toward MSC (S→S_tax). Equilibrium moves from Q_market to Q_social where MSB=MSC, reducing output and deadweight loss.
2 for diagram description, 2 for correction logic.

Q16. [4 marks]
For: equity — everyone accesses knowledge regardless of income (non-excludable benefit). Against: opportunity cost of tax funds; may not target poor. Evaluation: net equity gain if access gap large.
2 for equity justification, 2 for counter / eval.

Q17. [3 marks]
Market Y DWL (30) > Market X (12). Difference due to higher elasticity or larger market in Y, so tax distorts more.
1 compare, 2 reason.

Q18. [4 marks]
Permits cap total pollution (env effectiveness), allow low-cost abaters to sell (efficiency). Limit: monitoring needed, initial allocation disputed.
2 for pros, 2 for limits/eval.

Q19. [3 marks]
Non-excludable, non-rivalrous [2]. Private market under-provides because free-rider problem → no profit incentive [1].

Q20. [4 marks]
Short-term gain (28→41%) shows education works; drop to 33% shows weak persistence. Effective only with reinforcement.
2 evidence, 2 eval of durability.
