Case Study: The Electric Vehicle Transition in Singapore
Extract 1: Trends in Electric Vehicle (EV) Registrations and Charging Infrastructure
Table 1 shows the number of new Electric Vehicle (EV) registrations and the number of public charging points in Singapore from 2019 to 2023.
| Year | New EV Registrations (units) | Public Charging Points (units) | Average Price of Petrol ($/litre) |
|---|---|---|---|
| 2019 | 1,200 | 1,600 | 2.10 |
| 2020 | 1,850 | 2,100 | 1.95 |
| 2021 | 3,500 | 3,200 | 2.30 |
| 2022 | 8,200 | 4,500 | 2.65 |
| 2023 | 14,500 | 6,800 | 2.80 |

Extract 2: Government Policy on EV Adoption
In an effort to meet its Green Plan 2030 targets, the Singapore government has implemented several measures to encourage the adoption of Electric Vehicles (EVs).
- EV Early Adoption Incentive (EEAI): A rebate of up to $45,000 is provided for buyers of fully electric cars, effectively lowering the purchase price.
- Charging Infrastructure Grant: The government provides grants to private operators to install public charging stations, aiming to have 60,000 charging points by 2030.
- Carbon Tax: A carbon tax was increased from 25 per tonne in 2024, affecting the operating costs of internal combustion engine (ICE) vehicles indirectly through fuel supply chains.
However, critics argue that the high upfront cost of EVs remains a barrier for middle-income households. Furthermore, there are concerns about the strain on the national power grid if EV adoption accelerates too rapidly without sufficient renewable energy sources.
Extract 3: Consumer Survey on EV Adoption Barriers
A recent survey of 2,000 potential car buyers in Singapore revealed the following reasons for hesitancy in switching to EVs:
- Range Anxiety (45%): Fear of running out of battery before reaching a charging point.
- High Upfront Cost (30%): EVs are perceived as significantly more expensive than comparable petrol cars.
- Charging Time (15%): Concerns that charging takes too long compared to refuelling.
- Other (10%): Lack of model variety, resale value concerns.

Answer Key and Marking Scheme
Paper: Practice Paper 1 (Version 1 of 5)
Topic: Data Response - Microeconomics (Market Failure & Intervention)
Section A: Data Interpretation and Basic Concepts
1. With reference to Table 1 in Extract 1, compare the growth in new EV registrations with the growth in public charging points from 2019 to 2023.
[2 marks]
- Marking Criteria:
- 1 mark for stating the direction/magnitude of change for EV registrations.
- 1 mark for comparing it with charging points (using comparative language).
- Suggested Answer:
- New EV registrations increased significantly from 1,200 in 2019 to 14,500 in 2023 (more than 10-fold increase) [1].
- In contrast, public charging points increased from 1,600 to 6,800 (approx. 4-fold increase). Thus, the growth rate of EV registrations was much faster than the growth in charging infrastructure [1].
2. Describe the trend in the average price of petrol from 2019 to 2023 as shown in Table 1.
[2 marks]
- Marking Criteria:
- 1 mark for identifying the general direction.
- 1 mark for noting specific fluctuations or the overall rise.
- Suggested Answer:
- The average price of petrol generally increased from 2.80 in 2023 [1].
- However, it was not a steady increase; there was a slight dip in 2020 to $1.95 before rising steadily from 2021 onwards [1].
3. Using the concept of cross elasticity of demand (XED), explain the relationship between petrol cars and electric vehicles based on the data in Extract 1.
[3 marks]
- Marking Criteria:
- 1 mark for defining XED or identifying the sign (positive).
- 1 mark for identifying them as substitutes.
- 1 mark for linking to data (price of petrol up, demand for EVs up).
- Suggested Answer:
- Petrol cars and EVs are substitute goods, implying a positive Cross Elasticity of Demand (XED) [1].
- As the price of petrol (a complement to petrol cars) rose from 2021 to 2023, the cost of operating petrol cars increased [1].
- This led consumers to switch to EVs, causing EV registrations to rise sharply, confirming the substitute relationship [1].
4. Calculate the percentage increase in new EV registrations from 2021 to 2022.
[2 marks]
- Marking Criteria:
- 1 mark for correct formula/substitution.
- 1 mark for correct answer.
- Suggested Answer:
- Formula:
- Calculation:
- Answer: 134.3% (approx) [2]
5. State one possible reason for the sharp increase in EV registrations in 2022, other than the change in petrol prices.
[1 mark]
- Marking Criteria:
- 1 mark for any valid economic or policy reason.
- Suggested Answer:
- Introduction or enhancement of government subsidies (e.g., EV Early Adoption Incentive) [1].
- OR Increased availability of EV models in the market.
- OR Greater environmental awareness among consumers.
Section B: Market Analysis and Elasticity
6. With reference to Extract 2, explain how the EV Early Adoption Incentive (EEAI) affects the demand for electric vehicles.
[4 marks]
- Marking Criteria:
- 1 mark for identifying EEAI as a subsidy/price reduction.
- 1 mark for stating demand increases (shift right).
- 1 mark for explaining the mechanism (lower effective price/income effect).
- 1 mark for context (makes EVs more affordable relative to ICE cars).
- Suggested Answer:
- The EEAI acts as a subsidy to consumers, reducing the effective purchase price of EVs by up to $45,000 [1].
- This increases the purchasing power of consumers, making EVs more affordable [1].
- As a result, the demand for EVs increases, represented by a rightward shift of the demand curve [1].
- This is particularly effective for middle-income households who are price-sensitive [1].
7. Explain why the price elasticity of supply (PES) for public charging points might be relatively inelastic in the short run.
[4 marks]
- Marking Criteria:
- 1 mark for defining PES or stating inelastic (<1).
- 1 mark for time lag factor.
- 1 mark for infrastructure/capital constraints.
- 1 mark for regulatory/planning constraints.
- Suggested Answer:
- PES is likely inelastic in the short run because increasing the number of charging points requires significant time and capital investment [1].
- Infrastructure development involves planning approval, construction, and grid upgrades, which cannot be done instantly [1].
- Therefore, even if demand for charging rises, the supply cannot respond quickly to price signals or incentives [1].
- This leads to a low PES value (<1) in the short term [1].
8. Using a demand and supply diagram, illustrate the impact of the EV Early Adoption Incentive (EEAI) on the market for electric vehicles. Label the initial and new equilibrium price and quantity.
[6 marks]
- Marking Criteria:
- 1 mark for correctly labelled axes (Price, Quantity).
- 1 mark for downward sloping Demand (D) and upward sloping Supply (S).
- 1 mark for initial equilibrium ().
- 1 mark for rightward shift of Demand curve ( to ). Note: Subsidy to consumers shifts Demand. If treated as production subsidy, Supply shifts right. Both acceptable if explained. EEAI is consumer-facing, so Demand shift is more precise.
- 1 mark for new equilibrium () showing higher Quantity and potentially higher Market Price (if Supply is upward sloping) or lower Effective Price.
- 1 mark for clear labeling of shifts and equilibria.
- Suggested Answer:
- Diagram shows P on Y-axis, Q on X-axis.
- Initial D1 and S1 intersect at E1 ().
- D1 shifts right to D2 due to subsidy.
- New equilibrium E2 at ().
- (Quantity increases).
- (Market price received by sellers may rise, but consumer pays ).
9. With reference to Extract 3, discuss whether 'Range Anxiety' or 'High Upfront Cost' is a more significant barrier to EV adoption in Singapore.
[6 marks]
- Marking Criteria:
- 1-2 marks for identifying 'Range Anxiety' as significant (45% vs 30%).
- 1-2 marks for explaining why Range Anxiety is critical (infrastructure lag).
- 1-2 marks for evaluating 'High Upfront Cost' (subsidies mitigate this).
- 1 mark for a justified conclusion.
- Suggested Answer:
- 'Range Anxiety' appears more significant as 45% of respondents cited it, compared to 30% for cost [1].
- This is because Singapore is small, but the perception of insufficient charging points (Extract 1 shows lag in infrastructure growth) creates psychological barriers [1].
- However, 'High Upfront Cost' is also major, but government subsidies (EEAI) directly address this, potentially reducing its impact over time [1].
- Range anxiety is harder to solve quickly as it requires physical infrastructure build-up (inelastic supply) [1].
- Therefore, Range Anxiety is currently the more significant barrier because it is structural and less easily mitigated by financial incentives alone [1].
Section C: Market Failure and Policy Evaluation
10. Explain how the consumption of petrol cars generates negative externalities.
[4 marks]
- Marking Criteria:
- 1 mark for defining negative externality.
- 1 mark for identifying the third party affected.
- 1 mark for explaining the divergence (MSC > MPC).
- 1 mark for identifying the welfare loss/overconsumption.
- Suggested Answer:
- Negative externality occurs when the social cost of consumption exceeds the private cost [1].
- Petrol car emissions cause air pollution and health issues for third parties (society) who are not compensated [1].
- The driver only considers private costs (petrol, maintenance), ignoring the external cost [1].
- This leads to overconsumption of petrol cars relative to the social optimum, causing a deadweight loss [1].
11. With reference to Extract 2, explain how the Carbon Tax aims to correct the market failure caused by petrol cars.
[4 marks]
- Marking Criteria:
- 1 mark for identifying Carbon Tax as increasing cost.
- 1 mark for explaining internalization of externality.
- 1 mark for shifting Supply (or reducing Demand via higher prices).
- 1 mark for moving towards social optimum.
- Suggested Answer:
- The Carbon Tax increases the cost of production for fuel suppliers, which is passed on to consumers as higher petrol prices [1].
- This forces consumers to internalize the external cost of pollution [1].
- Higher petrol prices reduce the demand for petrol cars (or shift supply of fuel left), reducing quantity consumed [1].
- This helps align the private outcome with the social optimum, reducing the welfare loss [1].
12. Discuss the extent to which government subsidies (such as the EEAI) are more effective than carbon taxes in promoting EV adoption in Singapore.
[10 marks]
-
Marking Criteria:
- Knowledge (2 marks): Understanding of subsidies and taxes.
- Analysis (4 marks): How subsidies work (shift D right, lower effective price); How taxes work (shift S left/D left, raise cost of alternatives).
- Evaluation (4 marks): Comparison of effectiveness, equity, fiscal impact, and limitations.
-
Suggested Answer:
Introduction:
- Define subsidies (EEAI) and carbon taxes. State that both aim to correct market failure but through different mechanisms.
Argument for Subsidies (EEAI) being more effective:
- Direct Incentive: Subsidies directly lower the upfront cost of EVs, addressing the "High Upfront Cost" barrier (30% of survey) [1].
- Demand Shift: They shift the demand curve for EVs to the right, increasing quantity demanded immediately [1].
- Political Acceptability: Subsidies are popular with consumers, whereas taxes are often unpopular [1].
- Targeted: EEAI specifically targets EV buyers, whereas carbon taxes affect all fuel users broadly [1].
Argument for Carbon Taxes being more effective (or limitations of Subsidies):
- Fiscal Cost: Subsidies impose a heavy burden on the government budget (opportunity cost of other public goods) [1].
- Inefficiency: Subsidies may benefit wealthy buyers who would have bought EVs anyway (deadweight loss of subsidy) [1].
- Carbon Tax Internalizes Externality: Taxes directly address the negative externality of petrol cars by making them pay for pollution, which is economically efficient [1].
- Long-term Signal: Taxes provide a long-term price signal encouraging innovation and alternative transport, whereas subsidies might be temporary [1].
Evaluation/Conclusion:
- Subsidies are more effective in the short run for boosting adoption rates quickly by overcoming price barriers [1].
- However, carbon taxes are more effective in the long run for ensuring sustainable behavior change and correcting market failure efficiently without fiscal strain [1].
- Judgment: In Singapore’s context, a combination is likely most effective. Subsidies kickstart the market, while taxes discourage the alternative. However, if forced to choose, subsidies may be more effective for the specific goal of EV adoption numbers in the short term, while taxes are better for overall environmental outcomes [2].
- Final conclusion must be justified.
