Section A: Multiple-Choice and Short Answer (1–10) — 20 marks
Tests AO1 and AO2 on microeconomic concepts.
1. Define "loss aversion" in behavioural economics. [2]
2. A consumer refuses to switch from their current broadband plan despite a cheaper alternative. Which behavioural bias best explains this? [1]
3. Explain the sunk cost fallacy with a daily-life example. [2]
4. Using marginal analysis, state the condition for rational consumer optimisation. [1]
5. In a prisoner's dilemma game with pure strategies, what is a Nash equilibrium? [2]
6. Give one real-world example of moral hazard in insurance markets. [1]
7. What is the Coase Theorem's requirement for efficient resolution of externalities? [2]
8. Define "club good" and give one example. [2]
9. A worker exerts less effort after receiving a fixed bonus. Name the principal-agent problem illustrated. [1]
10. State one strategy to reduce adverse selection in product markets. [1]
Section B: Data and Case Analysis (11–15) — 15 marks
Tests AO1 and AO2 using provided stimuli.
11. The table below shows payoffs (in $000) for two firms, X and Y, choosing High or Low advertising.
| Y: High | Y: Low | |
|---|---|---|
| X: High | 10, 10 | 18, 4 |
| X: Low | 4, 18 | 12, 12 |
Identify the Nash equilibrium(s). [3]
Image pending generation: table for Q11.
12. Using the matrix in Q11, explain why (High, High) may be suboptimal compared to (Low, Low). [3]
13. A common fishery is depleted because no one owns it. Name the concept and explain with property rights. [3]
14. A government issues tradable permits for pollution. Show how this internalises externality using Coase logic. [3]
15. Evaluate one nudge policy to increase retirement savings (AO2). [3]
Section C: Extended Microeconomic Reasoning (16–20) — 15 marks
Tests AO2 synthesis.
16. Compare bounded rationality and bounded self-interest in firm pricing. [3]
17. Using game theory, suggest how cooperation can be sustained among rivals. [3]
18. Analyse how asymmetric information causes market failure in used cars. [3]
19. Apply the Capital Approach to a local microenterprise's sustainable growth. [3]
20. Critically discuss whether behavioural economics replaces rational models. [3]

Syllabus-first inferred; no past-paper evidence used.
Section A Answers (20 marks)
1. [2 marks] Loss aversion: tendency to feel losses more strongly than equivalent gains.
Teaching note: Define as pain of loss > joy of gain. Mark: 1 for definition, 1 for behavioural context.
2. [1 mark] Status quo bias.
Note: Not endowment effect (no ownership transfer).
3. [2 marks] Sunk cost fallacy: continuing due to past unrecoverable costs. Example: finishing a paid movie despite disliking it.
Marks: 1 concept, 1 example.
4. [1 mark] MB=MC (marginal benefit equals marginal cost).
5. [2 marks] Nash equilibrium: no player can benefit by changing strategy unilaterally.
Marks: 1 definition, 1 pure-strategy context.
6. [1 mark] E.g., car owner drives recklessly after insuring.
7. [2 marks] Low transaction costs + defined property rights enable bargaining to efficient outcome.
Marks: 1 each.
8. [2 marks] Club good: excludable, non-rival up to capacity. E.g., cable TV.
Marks: 1 def, 1 example.
9. [1 mark] Moral hazard.
10. [1 mark] Screening (e.g., warranties).
Section B Answers (15 marks)
11. [3 marks] Nash: (High,High) and (Low,Low).
Working: For (High,High): X deviates to Low → 4<10 no; Y deviates → 4<10 no. For (Low,Low): X deviates to High → 18>12 yes, so not stable? Check: Y at Low, X Low→12, X High→18 so X will deviate, thus (Low,Low) NOT Nash. Only (High,High) is Nash. Correction: (High,High) only.
Marks: 1 for correct ID, 2 for verification.
12. [3 marks] (High,High)=10 each; (Low,Low)=12 each but not equilibrium due to incentive to cheat. Suboptimal due to prisoner dilemma.
Marks: 1 compare, 2 explain dilemma.
13. [3 marks] Tragedy of commons. No property rights → overfishing. Defined rights allow exclusion/management.
Marks: 1 name, 2 explain.
14. [3 marks] Permits create property rights; firms trade to lowest-cost abater, mimicking Coase.
Marks: 1 permits, 2 internalise.
15. [3 marks] Auto-enrolment nudge: default into savings, raises participation. AO2: low cost, preserves choice.
Marks: 1 policy, 2 eval.
Section C Answers (15 marks)
16. [3 marks] Bounded rationality: limited info in pricing; bounded self-interest: fairness in price.
Marks: 1.5 each.
17. [3 marks] Repeat games, trigger strategies punish deviation.
Marks: 1 mechanism, 2 sustain.
18. [3 marks] Sellers know quality, buyers don't → lemons market collapses.
Marks: 1 asymmetry, 2 failure.
19. [3 marks] Capital Approach: build human + social capital for microfirm resilience.
Marks: 1 approach, 2 apply.
20. [3 marks] Not replace but complement; rational as benchmark, behavioural as realism.
Marks: 1 stance, 2 discuss.
