A-Level Economics H3 Quiz - Data Response (Answer Key)
Total Marks: 40
Topic: Data Response (syllabus-first; no past-year claim)
Section A Answers
1. [1 mark]
Answer: Firm / producer decision-making (or corporate agent).
Teaching note: A nudge influences economic agents; here firms are the agents adopting carbon pricing. Common mistake: saying "consumer" when text says firms.
2. [1 mark]
Answer: Nominal values ignore inflation; real comparison needs deflator.
Teaching note: Nominal GDP not adjusted for price changes; cross-year comparison overstates growth if inflation positive.
3. [1 mark]
Answer: Endowment effect.
Teaching note: Owned subsidised item valued more once possessed; keeping longer reflects endowment effect.
4. [1 mark]
Answer: Rate of change of renewable share per year.
Teaching note: Slope = rise/run; here % points per year.
5. [2 marks]
Answer: (Hold, Hold) = (3,3).
Working: For X, if Y Expand: X gets 2 (Expand) vs 1 (Hold) → Expand best; if Y Hold: X gets 5 (Expand) vs 3 (Hold) → Expand best. So Expand dominant for X. For Y symmetric, Expand dominant. But (Expand,Expand)=(2,2) not stable? Wait pure NE: check (Hold,Hold): X deviating to Expand gets 5>3, so not NE. Actually Expand is dominant for both, so NE = (Expand,Expand). Correction: NE = (Expand, Expand) with (2,2).
Marking: 1 mark dominant strategy identified, 1 mark correct cell.
6. [1 mark]
Answer: Lack of clearly defined property rights.
Teaching note: Commons open access leads overuse; property rights internalise.
7. [1 mark]
Answer: Income inequality increased.
Teaching note: Gini 0 to 1; higher = more unequal.
8. [1 mark]
Answer: Losses felt more strongly than equivalent gains, avoiding losses even at net benefit.
Teaching note: Kahneman-Tversky; loss aversion coefficient >1.
Section B Answers
9. [2 marks]
Answer: Low transaction costs / clearly defined property rights.
Teaching note: Coase requires negotiation feasible; 1 mark concept, 1 mark application.
10. [3 marks]
Mean = (2.1+6.4+1.3+4.0)/4 = 13.8/4 = 3.45t. [2 marks]
Limitation: Mean skewed by B (6.4t); hides variation, poor for targeted policy. [1 mark]
Teaching note: Show sum and divide; mention outlier.
11. [2 marks]
Answer: Efficiency wages / monitoring / co-payment. [1] Explain: aligns agent with principal. [1]
12. [3 marks]
Status quo bias: people stick default [1]; default enrolment exploits inertia [1]; bounded will-power/procrastination avoided [1].
13. [2 marks]
Answer: Correlation not causation; omitted variables (e.g., education) [1]; or reverse causality [1].
14. [3 marks]
Advertise dominant for both (3>1, 6>4) [1]; (Advertise,Advertise)=(3,3) but (Not,Not)=(4,4) better [1]; so yes prisoner's dilemma: individual rational leads to worse joint outcome [1].
Section C Answers
15. [3 marks]
Using Capital Approach: produced capital (EVs) up, but natural capital (grid emissions) worsened [1]; unintended: carbon leakage to power sector [1]; sustainability questionable if natural capital depleted [1].
16. [4 marks]
Capital Approach: sustainability if total capital constant [1]; natural -2%, human +1% net -1% absent others [1]; if produced/financial not offset, unsustainable [1]; evaluate trade-off substitutability critically [1].
17. [3 marks]
Post hoc fallacy [1]; correlation not causation [1]; other factors (e.g., global demand) may drive growth [1].
18. [4 marks]
Alternative nudge: default opt-out renewable [1]; evaluate: preserves choice, increases welfare if green preferred [1]; contrast status quo exploitation [1]; consider behavioural liberty [1].
19. [3 marks]
Adverse selection: high-risk disproportionately buy (70%) [1]; insurer pool skewed [1]; premiums rise, low-risk exit [1].
20. [4 marks]
Matrix: (Expand,Expand)=2,2; (Hold,Hold)=3,3. [1] Cooperate via repeated game / tradeable permit [1]; evaluate: joint gain 6 vs 4 [1]; sustainability if resource use cut [1].
