Section A: Market Mechanism and Elasticity (Questions 1–7) [21 marks]
1. Explain the signalling function of the price mechanism in a free market. [2]
2. The price of coffee rises from 4to5 per cup, and quantity demanded falls from 100 to 80 cups per day. Calculate the price elasticity of demand (PED) using the midpoint formula. [3]
3. With reference to the extract below, explain whether rice is a normal or inferior good based on the income elasticity of demand (YED) value.
Extract: A study in Country B shows that when average household income rose by 10%, demand for premium rice fell by 4%, while demand for staple rice rose by 2%. [3]
4. Define cross elasticity of demand (XED) and state the sign of XED for two substitute goods. [2]
5. A good has PED = 0.4 and PES = 1.2. If a subsidy lowers the price by 10%, compare the percentage change in quantity demanded and quantity supplied. [2]
6. Use a demand and supply diagram to show how a decrease in supply of lithium affects the equilibrium price and quantity in the battery market. [3]
Image pending generation: diagram for Q6.
7. Explain how the rationing function of price prevents a persistent shortage in a market without government intervention. [3]
Section B: Government Intervention (Questions 8–13) [18 marks]
8. Distinguish between a maximum price and a minimum price, giving one example of each. [3]
9. A government imposes a specific tax of $2 per unit on a good. Using a diagram, show the effect on equilibrium price and quantity. [3]
Image pending generation: diagram for Q9.
10. Explain how the incidence of a subsidy differs when demand is inelastic versus elastic. [3]
11. A price ceiling is set below the equilibrium price in the rental housing market. Explain the likely resulting market condition and one unintended consequence. [3]
12. Calculate the change in consumer expenditure when price falls from 10to8 and quantity demanded rises from 50 to 70, stating whether demand is elastic or inelastic. [3]
13. Discuss whether a quota on imported cars necessarily improves welfare for domestic consumers. [3]
Section C: Firms and Market Structures (Questions 14–20) [21 marks]
14. State the profit-maximising condition for a firm and explain why MC must be rising at that output. [3]
15. Explain how firms in monopolistic competition use non-price competition. [2]
16. With reference to Extract X, assess whether FoodDash exhibits monopoly power in the local delivery market.
Extract X: FoodDash holds 65% of the food delivery market in City K. It uses algorithms to set delivery fees and has exclusive contracts with 200 restaurants. New entrants face high customer acquisition costs due to brand loyalty. [4]
17. A firm has demand P = 30 – 0.4Q. Calculate PED at P = $14 and advise if it should cut price to raise revenue. [4]
18. Using a diagram, explain how a monopolist restricts output compared to a perfectly competitive market. [3]
Image pending generation: diagram for Q18.
19. Evaluate the view that profit satisficing is more realistic than profit maximisation in large firms. [3]
20. Discuss whether price discrimination by a cinema improves overall social welfare. [3]
Answers
TuitionGoWhere Practice Paper — Economics H2 A-Level (Version 2) Answer Key
Total Marks: 60
Section A: Market Mechanism and Elasticity (21 marks)
Q1 [2 marks]
- Signalling function: Prices act as signals to both consumers and producers about relative scarcity. (1 mark)
- A rise in price signals scarcity/profit opportunity, incentivising producers to increase supply and consumers to reduce demand. (1 mark) Teaching note: The price mechanism coordinates without central planning. Students often confuse signalling with rationing — signalling is about information, rationing is about allocation under shortage.
Q2 [3 marks] Midpoint formula: %ΔQ = (80–100)/((80+100)/2) = –20/90 = –22.22%; %ΔP = (5–4)/4.5 = 1/4.5 = 22.22%. PED = –22.22 / 22.22 = –1.0 (absolute value 1.0, unit elastic). (3 marks: 1 for Q change, 1 for P change, 1 for final) Common mistake: Using simple % (100→80 = –20%) without midpoint gives –1.0 here by chance but fails at other values.
Q3 [3 marks]
- Premium rice YED = –4% / 10% = –0.4 → inferior good (demand falls as income rises). (1.5 marks)
- Staple rice YED = +2% / 10% = +0.2 → normal good. (1.5 marks) Note: Negative YED defines inferior; positive defines normal. Premium rice is inferior in this context.
Q4 [2 marks]
- XED = %ΔQd of good A / %ΔP of good B. (1 mark)
- For substitutes, XED > 0 (positive sign). (1 mark)
Q5 [2 marks]
- %ΔQd = PED × %ΔP = 0.4 × (–10%) = –4% (demand falls 4%). (1 mark)
- %ΔQs = PES × %ΔP = 1.2 × (–10%) = –12% (supply falls 12%). (1 mark) Supply responds more strongly due to higher elasticity.
Q6 [3 marks]
- Diagram shows D vertical? No: D downward sloping, S1 left to S2. (1 mark)
- New equilibrium E2: P↑, Q↓. (1 mark)
- Lithium is input; battery market supply falls, price rises, quantity falls. (1 mark) Expected visual: Leftward S shift, label P2> P1, Q2< Q1.
Q7 [3 marks]
- When price below equilibrium → excess demand (shortage). (1)
- Rising price rations goods to those willing/able to pay, quantity supplied rises. (1)
- Market reaches equilibrium, no persistent shortage without intervention. (1)
Section B: Government Intervention (18 marks)
Q8 [3 marks]
- Max price: legal ceiling below eq price (e.g. rent control). (1.5)
- Min price: legal floor above eq price (e.g. minimum wage). (1.5)
Q9 [3 marks]
- Supply shifts up by $2 (S to S+tax). (1)
- New eq: Q↓, Pc (consumer) > P0, Pp (producer) < P0. (2) Visual: parallel shift, burden shared.
Q10 [3 marks]
- Inelastic demand: consumers bear more subsidy benefit as price drop small but Q unchanged much. (1.5)
- Elastic demand: larger Q response, producers receive more effective support. (1.5)
Q11 [3 marks]
- Shortage (excess demand) as Qd > Qs at ceiling. (1.5)
- Unintended: black market, deterioration of quality. (1.5)
Q12 [3 marks]
- Initial CE = 10×50 = 500;NewCE=8×70=560. Rise of $60. (2)
- Outlay rose when price fell → demand inelastic (revenue inverse to price). (1)
Q13 [3 marks]
- Quota limits imports, helps domestic producers, may raise price. (1)
- Consumers face higher price, less choice → welfare may fall. (1)
- Not necessarily improvement; depends on externalities/infant industry. (1)
Section C: Firms and Market Structures (21 marks)
Q14 [3 marks]
- Condition: MR = MC. (1)
- MC rising ensures max not min profit (if MC falling, expanding raises profit). (2)
Q15 [2 marks]
- Advertising, branding, product differentiation. (1)
- Not price cuts, to build loyalty. (1)
Q16 [4 marks]
- High share 65% suggests dominance. (1)
- Exclusive contracts, barriers = monopoly power signs. (1.5)
- But contestable? Brand loyalty high → real power. (1.5) Descriptor: Identify 2+ features, evaluate context.
Q17 [4 marks] At P=14, Q = (30–14)/0.4 = 40. dQ/dP = –2.5. PED = –2.5 × (14/40) = –0.875. |PED|<1 inelastic. (3) Do NOT cut price; revenue falls. (1)
Q18 [3 marks]
- PC: Pc=MC, Qc. Monopoly: MR=MC, Qm<Qc, Pm>Pc. (3) Visual: show MR, restricted output.
Q19 [3 marks]
- Satisficing: managers meet acceptable profit, avoid risk. (1)
- Large firms: separation ownership/management → realistic. (2)
Q20 [3 marks]
- Cinema charges different groups; fills seats, may raise producer surplus. (1)
- If allocative efficiency improves (empty seats used) welfare up. (1)
- But consumer surplus transfer; net ambiguous. (1)
