20. With reference to Extract 3, discuss whether government intervention in the local bakery market would necessarily improve consumer outcomes. [8]

Extract 3: Small neighbourhood bakeries in Singapore face rising rent and ingredient costs. Some consumers complain about higher bread prices, while owners say margins are thin. The government is considering a subsidy.

Answer Key – TuitionGoWhere Practice Paper (Microeconomics) Version 1

Total Marks: 60
Level: A-Level H2 Economics
Topic: Microeconomics

Section A (16 marks)

Q1 [2 marks] The signalling function of the price mechanism communicates information to consumers and producers. A rise in price signals scarcity and encourages producers to increase supply while discouraging consumption. Marking: 1 mark for definition, 1 mark for example of rise/fall signalling.

Q2 [2 marks] A movement along the demand curve is caused by a change in the price of the good itself; a shift in the demand curve is caused by a change in a non-price determinant (e.g. income, tastes). Marking: 1 mark each for correct distinction.

Q3 [2 marks] Consumer surplus is the difference between what consumers are willing to pay (shown by the demand curve) and what they actually pay (market price), summed over all units. Marking: 1 mark willingness, 1 mark actual payment/diagram area.

Q4 [2 marks] $YED = -0.4$ → inferior good (negative YED). Type: inferior good (e.g. instant noodles). Marking: 1 mark inferior, 1 mark correct type identification.

Q5 [2 marks] Diagram: price ceiling below equilibrium creates excess demand (shortage). Label Pmax below Pe, Qd > Qs. Marking: 1 mark diagram with Pmax below Pe, 1 mark shortage shown.

Q6 [2 marks] A firm may satisfice due to separation of ownership and control (managers prefer steady growth over max profit) or lack of info to maximise profit. Marking: 1 mark reason, 1 mark brief explanation.

Q7 [2 marks] $100 - 2P = 20 + 2P$ → $80 = 4P$ → $P = 20$ . $Q = 100 - 40 = 60$ . Equilibrium price = $20, quantity = 60. Marking: 1 mark correct P, 1 mark correct Q.

Q8 [2 marks] Any two: income, tastes/preferences, price of related goods, expectations, number of consumers. Marking: 1 mark each.

Section B (24 marks)

Q9 [3 marks] EV demand rises → more EVs produced → derived demand for lithium increases → lithium price and quantity rise. Diagram must show EV D shift right, lithium D shift right. Marking: 1 mark causal chain, 2 marks diagram with both markets.

Q10 [3 marks] Derived demand: demand for lithium is derived from demand for EVs. As EV demand rises (Extract 1: +35% sales), lithium demand shifts right (price +30%). Marking: 1 mark definition, 2 marks applied to extract.

Q11 [3 marks] Midpoint PED = $\frac{(80-100)/((80+100)/2)}{(5-4)/((5+4)/2)} = \frac{-20/90}{1/4.5} = \frac{-0.222}{0.222} = -1.0$ . Absolute 1.0 (unit elastic). Marking: 1 mark formula, 1 mark substitution, 1 mark answer.

Q12 [4 marks] Subsidy shifts supply right → price falls, quantity rises. Consumer expenditure = P×Q may rise/fall depending on PED; producer revenue may rise due to higher Q. Diagram shows S2 right. Marking: 1 diagram, 1 price/qty effect, 2 expenditure/revenue explanation.

Q13 [2 marks] Oligopoly firms compete via non-price (advertising, network) and price matching to avoid price wars. Marking: 1 mark non-price, 1 mark price matching.

Q14 [6 marks] Tax shifts S left → price up, Q down. CS falls (less area under D above P). DWL = loss of mutually beneficial trades. Diagram with tax wedge and DWL triangle. Marking: 2 diagram, 2 CS, 2 DWL.

Section C (20 marks)

Q15 [8 marks] For: fewer firms → scale economies → lower prices; against: less competition → higher prices, reduced choice. Use CS diagram. Conclusion: ambiguous, depends on regulation. Marking: 2 for, 2 against, 2 diagram, 2 judgment.

Q16 [8 marks] Consumer role: demand shift to sustainable. Limits: info asymmetry, cost, externalities need gov. Balanced: individual + systemic. Marking: 2 consumer, 2 barriers, 2 gov need, 2 conclusion.

Q17 [4 marks] Higher wages signal labour scarcity → workers incentivised to enter; firms signal needs via pay. Marking: 2 signalling, 2 incentive.

Q18 [6 marks] Quota limits import supply → domestic price up, Q down. CS falls, PS rises. Diagram with quota line. Marking: 2 diagram, 2 CS, 2 PS.

Q19 [6 marks] Price discrimination (e.g. student vs adult) raises revenue if PED differs. Not always best: needs market power, no resale. Alternatives: advertising. Marking: 2 method, 2 condition, 2 eval.

Q20 [8 marks] For: subsidy lowers bread price, aids consumers. Against: thin margins already, may not reach consumers, opportunity cost. Extract 3 rent/cost. Marking: 2 for, 2 against, 2 extract use, 2 conclusion.
