Answers

Answer Key: TuitionGoWhere Practice Paper - Economics H2 A-Level (Version 2)

Section A: Short Structured (16 marks)

Q1 (2m): The signalling function means that changes in price send information to consumers and producers about scarcity. A rising price signals relative scarcity and encourages producers to produce more while consumers reduce consumption.
Marking: 1m for definition of signalling, 1m for example of price change conveying info.

Q2 (2m): A movement along the demand curve is caused by a change in the good's own price; a shift in demand is caused by a non-price determinant (e.g. income, tastes).
Marking: 1m each correct distinction.

Q3 (2m): Consumer surplus is the difference between what a consumer is willing to pay and what they actually pay. It measures net benefit to consumers.
Marking: 1m definition, 1m reference to willingness vs actual payment.

Q4 (2m): Example: tea and coffee are substitutes. XED is positive because as price of coffee rises, demand for tea increases.
Marking: 1m valid substitute pair, 1m correct sign (positive).

Q5 (2m): A per-unit subsidy lowers producers' costs, shifting the supply curve to the right (increase in supply).
Marking: 1m cost reduction, 1m rightward shift.

Q6 (2m): Profit max where MR = MC. Marginal cost is the additional cost of producing one more unit of output.
Marking: 1m condition, 1m MC definition.

Q7 (2m): A maximum price below equilibrium creates a shortage (excess demand) as quantity demanded exceeds quantity supplied.
Marking: 1m below eq, 1m shortage stated.

Q8 (2m): Example: externalities (e.g. cigarette smoke) – consumer choice imposes cost on third parties not reflected in price.
Marking: 1m identify, 1m explanation.

Section B: Data and Diagram (24 marks)

Q9 (4m): Diagram: left EV market D shifts right → higher P,Q. Right lithium market derived D shifts right → higher P,Q.
Working: EV demand ↑ → more EVs produced → derived demand for lithium ↑ → lithium eq P and Q rise.
Marking: 2m diagrams correct with labels, 2m explanation of derived demand chain.

Q10 (3m):
%ΔQ = (60−80)/80 ×100 = −25%
%ΔP = (5−4)/4 ×100 = +25%
PED = |−25/25| = 1.0 (unit elastic)
Marking: 1m for each calculation step, final answer 1.0.

Q11 (4m): Tax shifts S left from S1 to S2. Eq P rises P1→P2, Q falls Q1→Q2. Burden shared depending on elasticities.
Marking: 2m diagram with shift and labels, 2m explanation of new eq.

Q12 (3m): Before min price, CS is area under D above P1. After min price at P3, CS is smaller (only Qd bought) and surplus stock exists.
Marking: 1m before, 1m after, 1m diagram reference.

Q13 (4m): (1) Time to build new houses – long construction lag. (2) Land scarcity limits quick supply response.
Marking: 2m each reason with elaboration.

Q14 (6m): Info asymmetry: dealers know more → buyers risk lemons. 6/10 cannot verify → pay higher price for poor quality. Govt intervention (regulation) may be needed.
Marking: 2m identify asymmetry, 2m apply extract, 2m consequence for consumers.

Section C: Extended (20 marks)

Q15 (8m): For: economies of scale, lower prices, better tech. Against: reduced competition, higher prices, less choice. Use CS diagram. Conclusion: ambiguous, depends on regulation.
Marking: 4m for/against points, 2m diagram, 2m balanced conclusion.

Q16 (6m): Consumer role yes, but market failure (externalities, info) means solo responsibility insufficient. Need govts/ producers.
Marking: 2m consumer role, 2m limitations, 2m evaluation.

Q17 (6m): Not always: needs market power, separable groups, no resale. Other strategies (advertising) may work better.
Marking: 2m conditions for PD, 2m limitations, 2m alternative view.
