Q1 [2 marks]
Loss aversion is the behavioural tendency where the pain of a loss is felt more strongly than the pleasure of an equivalent gain.
Marking: 1 mark for "loss felt stronger than gain", 1 mark for reference to equivalent magnitude or example.

Q2 [1 mark]
Sunk cost fallacy (or status quo bias). Most directly: sunk cost fallacy because router cost is sunk.
Note: Accept endowment effect if argued as ownership; but best fit is sunk cost.

Q3 [3 marks]
Sunk cost fallacy: continuing a project due to prior irreversible investment. Example: finishing a paid movie ticket despite disliking the film.
Marking: 1 def, 1 example, 1 explanation of irrationality.

Q4 [2 marks]
Rational firm maximises profit where MC = MR; beyond that, MC > MR reduces profit.
Marking: 1 for MC=MR condition, 1 for reasoning.

Q5 [1 mark]
Club good is excludable but non-rivalrous (e.g., cable TV); public good is non-excludable and non-rivalrous.

Q6 [3 marks]
Endowment effect: valuing owned items more than identical unowned ones. Causes inefficiency by reducing trade volume.
Marking: 1 def, 2 effect.

Q7 [2 marks]
Status quo bias: preference to maintain current state. Nudge: auto-enrolment in savings plan with opt-out.
Marking: 1 def, 1 nudge.

Q8 [2 marks]
Moral hazard: party takes more risk after being insured, as insurer bears cost.
Marking: 1 post-contract, 1 example/context.

Q9 [2 marks]
Nash equilibrium: no player can improve payoff by unilaterally changing strategy.
Marking: 1 no unilateral gain, 1 pure strategy context.

Q10 [2 marks]
Adverse selection: sellers know quality, buyers do not; bad cars drive out good (lemons).
Marking: 1 info asymmetry, 1 market outcome.
