• Write clearly and show reasoning for all marks.

Section A: Microeconomics Applications (30 marks)

1. [3 marks] A ride-hailing firm observes that after a price surge, existing users keep using the service but new users delay signing up. Using bounded rationality, explain one bias that may cause existing users to remain despite higher prices.

2. [4 marks] The following table shows payoffs (in $ million profit) for two coffee chains, BrewCo and BeanInc, choosing between "Aggressive Promotion" and "Stable Price".

	BrewCo: Aggressive	BrewCo: Stable
BeanInc: Aggressive	(4, 4)	(8, 2)
BeanInc: Stable	(2, 8)	(6, 6)

Identify the Nash equilibrium in pure strategies and explain your reasoning.

3. [3 marks] A government introduces tradable pollution permits to address a tragedy of the commons in a river fishery. State one condition required for the Coase Theorem to efficiently resolve the externality.

4. [4 marks] An insurer cannot observe a driver's true risk level. Explain how adverse selection may arise in this market and suggest one policy measure to reduce it.

5. [3 marks] A consumer refuses to cancel a gym membership she never uses because she already paid a joining fee. Name the fallacy illustrated and define it briefly.

6. [4 marks] Using the concept of competitive advantage, identify two of Porter's five forces that are most relevant when a new entrant threatens a dominant supermarket, and explain why.

7. [3 marks] A nudge places healthier snacks at eye level in a school canteen. State whether this is a change in incentives or a change in choice architecture, and explain.

8. [3 marks] A fisherman overuses a shared lake because he bears none of the depletion cost. Name the market failure and the type of good typically involved.

9. [3 marks] Define "loss aversion" and give one everyday example relevant to student spending.

Section B: Extended Microeconomics Reasoning (20 marks)

10. [10 marks] A smart-meter firm offers households a dynamic pricing plan: electricity is cheaper at night but expensive at peak. Some households procrastinate switching despite savings.
(a) Explain the behavioural concept of time-inconsistent preferences. [4]
(b) Evaluate how a default-enrolment nudge could improve household welfare, using bounded will-power. [6]

11. [10 marks] Two mobile game developers, PixCorp and PlayHub, must choose between "High Quality Update" and "Quick Cash Grab". Payoffs (in $m) are:

	PixCorp: High Quality	PixCorp: Cash Grab
PlayHub: High Quality	(10, 10)	(3, 14)
PlayHub: Cash Grab	(14, 3)	(5, 5)

(a) Identify the prisoner's dilemma outcome and the Nash equilibrium. [4]
(b) Discuss one strategy beyond pricing that could sustain cooperation. [6]
