CASE STUDY 1: SINGAPORE'S HOUSING MARKET — AFFORDABILITY AND POLICY RESPONSES

Total Marks: 50

Context

Singapore's housing market has experienced significant price fluctuations over the past decade. The government has implemented various measures to ensure housing remains affordable while maintaining a stable property market. The following data examines housing affordability, demand and supply factors, and the effectiveness of government interventions.

Extract 1: Government Cooling Measures (2018–2023)

In July 2018, the Singapore government introduced a package of property cooling measures to moderate demand and keep price increases in line with economic fundamentals. The measures included:

Additional Buyer's Stamp Duty (ABSD) rates were raised by 5 percentage points for all individuals and entities purchasing residential property, with rates of 20% for second properties and 25% for third and subsequent properties.
Loan-to-Value (LTV) limits on housing loans granted by financial institutions were tightened by 5 percentage points, reducing the maximum loan quantum for first housing loans to 75% (from 80%).
Minimum Cash Downpayment for second and subsequent housing loans was raised from 10% to 15%.

In December 2021, further measures were announced:

ABSD rates were raised again, with rates for second properties increasing to 25% and third properties to 30%.
Total Debt Servicing Ratio (TDSR) threshold was tightened from 60% to 55%.
Additional measures targeted the HDB resale market, including a 15-month wait-out period for private property owners buying HDB resale flats.

In April 2023, the government introduced another round of measures:

ABSD rates for foreign buyers were doubled from 30% to 60%.
ABSD rates for second properties purchased by Singapore citizens rose to 20% (from 17%).
The government increased the supply of private residential units under the Government Land Sales (GLS) programme by 25% for the 2023–2024 period.

Extract 2: Housing as a Merit Good

Housing is widely regarded as a merit good — a good that generates positive externalities and is considered essential for individual and societal well-being. Adequate housing contributes to better health outcomes, improved educational performance, and greater social stability. However, in a free market, housing may be under-consumed relative to the socially optimal level, particularly among lower-income households who may lack the ability to pay market prices.

In Singapore, the government's deep involvement in the housing market through the Housing & Development Board (HDB) reflects the recognition of housing as a merit good. Approximately 80% of Singapore's resident population lives in HDB flats, with about 90% of these households owning their homes. The government provides significant subsidies for new HDB flats, offers housing grants of up to SGD 80,000 for first-time buyers, and regulates the resale market to maintain affordability.

However, critics argue that extensive government intervention creates market distortions, including reduced incentives for private sector innovation in housing, potential misallocation of resources, and the risk of moral hazard where households take on excessive debt expecting government bailouts.

Extract 3: Rising Construction Costs and Supply Constraints

The construction industry in Singapore has faced significant cost pressures since 2020. According to the Building and Construction Authority (BCA), the tender price index for building works rose by 18.5% between 2020 and 2023. Key factors include:

Labour shortages: Tightening of foreign worker quotas and border restrictions during the COVID-19 pandemic reduced the available construction workforce by approximately 15%.
Material cost increases: Global supply chain disruptions led to steel prices rising by 30% and concrete prices by 12% between 2020 and 2022.
Regulatory compliance costs: Enhanced building safety and sustainability requirements added an estimated 5–8% to construction costs.

These supply-side constraints have contributed to delays in HDB Build-to-Order (BTO) project completion, with average waiting times increasing from 3–4 years pre-pandemic to 4–5 years in 2023. The reduced supply of completed units has placed upward pressure on resale prices.

CASE STUDY 2: SINGAPORE'S LABOUR MARKET — CHALLENGES AND POLICY RESPONSES

Total Marks: 50

Context

Singapore's labour market has undergone significant structural changes in recent years, driven by technological disruption, demographic shifts, and global economic uncertainties. The government has implemented various policies to address unemployment, enhance workforce skills, and maintain Singapore's competitiveness. The following data examines labour market trends and the effectiveness of policy interventions.

Extract 4: Structural Unemployment and Skills Mismatch

Singapore's labour market faces growing structural unemployment challenges as technological advancement reshapes industry requirements. According to the Ministry of Manpower, approximately 30% of jobs in Singapore are at high risk of displacement due to automation and digitalisation by 2030. Sectors such as retail, administrative support, and manufacturing are particularly vulnerable.

The skills mismatch problem is evident in the coexistence of job vacancies and unemployment. In 2023, there were approximately 98,000 job vacancies alongside 65,000 unemployed residents, suggesting that available workers lack the specific skills demanded by employers. The information and communications technology (ICT) sector, for example, reported over 15,000 unfilled positions in 2023, primarily in roles requiring data analytics, cybersecurity, and artificial intelligence expertise.

The government has responded with the SkillsFuture initiative, launched in 2015, which provides Singaporeans aged 25 and above with SGD 500 in credits for approved training courses. In 2020, an additional one-off SkillsFuture Credit top-up of SGD 500 was provided. The programme aims to encourage lifelong learning and facilitate workforce adaptation to changing industry needs.

Extract 5: Foreign Worker Policy and Labour Market Dynamics

Singapore's foreign worker policy has undergone significant tightening since 2010, with the government progressively reducing the Dependency Ratio Ceiling (DRC) — the maximum proportion of foreign workers a firm can employ — across various sectors. The DRC for the services sector was reduced from 40% to 35% in 2021, and further to 31.5% in 2023. For the manufacturing sector, the DRC was reduced from 60% to 55% in 2022.

The government's stated objectives include:

Encouraging firms to adopt productivity-enhancing technologies
Reducing reliance on low-cost foreign labour
Creating better-quality jobs for Singaporeans

However, businesses, particularly small and medium enterprises (SMEs), have expressed concerns about labour shortages and rising wage costs. The Singapore Business Federation reported in 2023 that 67% of SMEs faced difficulties in hiring local workers, and 45% experienced increased operating costs due to higher wages necessitated by labour shortages.

Extract 6: Fiscal Policy and Labour Market Support

During the COVID-19 pandemic, the Singapore government implemented unprecedented fiscal measures to support the labour market. The Jobs Support Scheme (JSS), introduced in 2020, provided wage subsidies of between 25% and 75% to employers to help them retain local workers. Total government expenditure on the JSS exceeded SGD 28 billion between 2020 and 2022.

Additional measures included:

SGUnited Jobs and Skills Package: Created approximately 100,000 opportunities comprising jobs, traineeships, and skills training places
Wage Credit Scheme: Co-funded wage increases for Singaporean employees earning up to SGD 5,000 per month
Progressive Wage Model (PWM): Expanded to cover more sectors, mandating minimum wage levels and training requirements for lower-wage workers

The fiscal support contributed to Singapore's resident unemployment rate declining from a peak of 4.1% in 2020 to 2.6% in 2023.

21. With reference to Extract 4, explain what is meant by structural unemployment and identify one cause of structural unemployment in Singapore. [3]

22. Using Extract 4, explain how the SkillsFuture initiative is intended to address the problem of skills mismatch in Singapore's labour market. [4]

23. With reference to Extract 5, explain how the reduction in the Dependency Ratio Ceiling (DRC) for the services sector would affect the labour market for local workers. [4]

24. Using a demand and supply diagram for labour, explain how the tightening of foreign worker quotas (Extract 5) would affect the equilibrium wage rate and employment level for local workers in the services sector. [6]

25. With reference to Extract 6, explain how the Jobs Support Scheme (JSS) functioned as an expansionary fiscal policy measure to support employment during the COVID-19 pandemic. [4]

26. Using the concept of opportunity cost, explain one possible effect on the Singapore government arising from the provision of SGD 28 billion in Jobs Support Scheme wage subsidies. [3]

27. Explain two consequences of the 'unprecedented levels of government stimulus' (Extract 6) on living standards in Singapore. [4]

Section C: Evaluation (Questions 28–30)

28. Discuss whether supply-side policies (such as SkillsFuture and foreign worker quota tightening) are more effective than fiscal policy measures (such as the Jobs Support Scheme) in addressing Singapore's long-term labour market challenges. [10]

29. With reference to the data and extracts, evaluate the effectiveness of Singapore's labour market policies in achieving low unemployment while maintaining income growth. [10]

30. Discuss the extent to which structural unemployment, rather than cyclical unemployment, represents the greater challenge for Singapore's labour market in the next decade. [10]

CASE STUDY 1: SINGAPORE'S HOUSING MARKET — AFFORDABILITY AND POLICY RESPONSES

Section A: Data Interpretation (Questions 1–5)

Question 1 [2 marks]

Answer: Both the HDB Resale Price Index and the Private Residential Price Index increased over the period 2015 to 2023 [1]. However, the Private Residential Price Index experienced greater volatility, declining from 100.0 to 97.0 between 2015 and 2016 before rising sharply to 136.2 by 2023, while the HDB Resale Price Index showed a more moderate decline to 97.8 in 2018 before rising to 126.4 in 2023 [1].

Marking notes:

Award [1] for identifying that both indices increased overall
Award [1] for comparative observation (e.g., private index more volatile, or private index rose more sharply, or HDB index declined for longer before recovering)
Accept any valid comparative observation supported by data

Question 2 [2 marks]

Answer: The Mortgage Servicing Ratio decreased slightly from 22.0% in 2015 to 21.2% in 2017 [1], before rising steadily from 21.8% in 2018 to 27.2% in 2023 [1].

Marking notes:

Award [1] for identifying the initial decline (2015–2017)
Award [1] for identifying the subsequent increase (2018–2023)
Accept description of overall trend (increased from 22.0% to 27.2%) with reference to specific data points

Question 3 [2 marks]

Answer: The Home Price-to-Income Ratio for Private Residential properties was consistently higher than for HDB flats throughout the period [1]. The HDB ratio increased from 4.5 to 5.3 (a rise of 0.8), while the Private ratio increased from 9.8 to 11.9 (a rise of 2.1), indicating that private housing became relatively less affordable over the period [1].

Marking notes:

Award [1] for noting that Private ratio is consistently higher than HDB ratio
Award [1] for comparative observation (e.g., Private ratio increased more in absolute terms, or the gap widened)
Accept any valid comparative observation supported by data

Question 4 [2 marks]

Answer: There is a positive relationship between the Overall Property Price Index and the Mortgage Servicing Ratio from 2018 to 2023 [1]. As the Overall Property Price Index increased from 102.4 to 132.1, the Mortgage Servicing Ratio also increased from 21.8% to 27.2%, suggesting that rising property prices led to higher mortgage servicing burdens for households [1].

Marking notes:

Award [1] for identifying the positive/direct relationship
Award [1] for supporting with data or providing a brief explanation
Accept "both increased" with data reference

Question 5 [4 marks]

Answer: Measure 1: Increase in Additional Buyer's Stamp Duty (ABSD) rates [1] The ABSD increase raised the transaction cost for property purchases, particularly for second and subsequent properties (20% and 25% respectively). This reduces demand by making property purchases more expensive, thereby discouraging speculative and investment demand [1].

Measure 2: Tightening of Loan-to-Value (LTV) limits [1] The reduction in LTV limits from 80% to 75% for first housing loans means buyers must provide a larger downpayment (25% instead of 20%). This reduces the ability of buyers to finance property purchases through borrowing, thereby constraining effective demand [1].

Marking notes:

Award [1] for each correctly identified measure (maximum 2 marks for identification)
Award [1] for each valid explanation of how the measure reduces demand (maximum 2 marks for explanation)
Accept other measures mentioned in Extract 1 (e.g., Minimum Cash Downpayment increase)
Explanation must link the measure to reduced demand (not just describe the measure)

Section B: Analysis and Application (Questions 6–12)

Question 6 [3 marks]

Answer: The tightening of LTV limits from 80% to 75% means that first-time homebuyers can borrow a smaller proportion of the property's value [1]. This requires buyers to provide a larger cash downpayment (25% instead of 20% of the property value) [1]. As a result, first-time homebuyers face a higher upfront financial burden, which may reduce their ability to purchase property, particularly if they have limited savings [1].

Marking notes:

Award [1] for explaining the change in borrowing capacity
Award [1] for explaining the impact on downpayment requirements
Award [1] for linking to reduced ability to purchase
Accept reference to reduced effective demand or constrained affordability

Question 7 [6 marks]

Answer:

Diagram (3 marks):

Correctly labelled axes: Price (vertical) and Quantity of private residential units (horizontal) [1]
Initial demand (D1) and supply (S1) curves with equilibrium (P1, Q1) [0.5]
Rightward shift of supply curve from S1 to S2 [1]
New equilibrium (P2, Q2) showing lower price and higher quantity [0.5]

Explanation (3 marks): The increase in Government Land Sales (GLS) supply by 25% increases the availability of land for private residential development [1]. This represents an increase in supply (rightward shift of the supply curve) as developers can build more units [1]. The increase in supply leads to a decrease in the equilibrium price (from P1 to P2) and an increase in the equilibrium quantity (from Q1 to Q2) of private residential units, ceteris paribus [1].

Marking notes:

Award up to [3] for the diagram (axes, curves, shifts, equilibrium points)
Award up to [3] for the explanation (identifying supply increase, explaining mechanism, stating price and quantity effects)
Explanation must reference the GLS supply increase specifically
Accept partial diagrams if explanation is strong

Question 8 [4 marks]

Answer: Factor 1: Labour shortages [1] The tightening of foreign worker quotas and border restrictions reduced the available construction workforce by approximately 15%. This increased labour costs for construction firms, raising the cost of production and shifting the supply curve for housing leftward, contributing to higher prices [1].

Factor 2: Material cost increases [1] Global supply chain disruptions led to steel prices rising by 30% and concrete prices by 12%. These higher input costs increased the cost of construction, reducing the profitability of housing development at existing price levels and shifting the supply curve leftward, contributing to upward pressure on prices [1].

Marking notes:

Award [1] for each correctly identified supply-side factor from Extract 3 (maximum 2 marks)
Award [1] for each valid explanation linking the factor to rising housing prices (maximum 2 marks)
Accept regulatory compliance costs as a third factor
Explanation must use supply-side reasoning (cost of production, supply curve shifts)

Question 9 [3 marks]

Answer: The price elasticity of supply (PES) for new HDB flats in the short run is likely to be low (inelastic, PES < 1) [1]. This is because the construction of HDB flats involves significant time lags due to planning, approval, and building processes, with average waiting times of 4–5 years as indicated in Extract 3 [1]. Additionally, supply is constrained by labour shortages and material cost increases, which limit the ability of producers to quickly increase output in response to price changes [1].

Marking notes:

Award [1] for stating that PES is likely low/inelastic
Award [1] for explaining time lags in construction (reference to Extract 3)
Award [1] for explaining supply constraints (labour, materials)
Accept reference to the concept that supply cannot respond quickly to price changes in the short run

Question 10 [4 marks]

Answer: Speculative demand for second and third properties is likely to be price elastic (PED > 1) [1]. This is because investment properties are not necessities and buyers have the option to delay purchases or invest in alternative assets [1]. When ABSD increases the effective price of property purchases (by adding 20–30% in transaction costs), the quantity demanded for speculative purchases falls more than proportionately [1]. Therefore, the ABSD is effective in reducing speculative demand because speculators are sensitive to price increases and can choose not to purchase when transaction costs rise significantly [1].

Marking notes:

Award [1] for identifying that speculative demand is likely price elastic
Award [1] for explaining why (not a necessity, substitutes available, luxury nature)
Award [1] for linking ABSD to an increase in effective price
Award [1] for explaining the disproportionate reduction in quantity demanded
Accept alternative reasoning if well-justified (e.g., if candidate argues demand is inelastic but ABSD still reduces quantity demanded)

Question 11 [6 marks]

Answer: A merit good is a good that generates positive externalities and is considered to be under-consumed if left to the free market [1].

Housing as a merit good (3 marks): Housing generates positive externalities as identified in Extract 2: adequate housing contributes to better health outcomes, improved educational performance, and greater social stability [1]. These benefits accrue not only to the occupants but also to society at large, meaning the social benefit of housing consumption exceeds the private benefit [1]. However, individuals may not fully consider these external benefits when making housing decisions, leading to consumption below the socially optimal level [1].

Market failure (2 marks): Market failure occurs because the free market equilibrium (where marginal private benefit equals marginal private cost) results in under-consumption relative to the socially optimal level (where marginal social benefit equals marginal social cost) [1]. Lower-income households may be particularly affected as they lack the ability to pay market prices, resulting in inadequate housing consumption despite the significant social benefits it provides [1].

Marking notes:

Award [1] for defining merit good
Award up to [3] for explaining how housing exhibits merit good characteristics (positive externalities, social vs. private benefit, under-consumption)
Award up to [2] for explaining market failure (divergence between private and social optimum, reference to lower-income households)
Answers must reference Extract 2

Question 12 [6 marks]

Answer:

Diagram (3 marks):

Correctly labelled axes: Price/Cost/Benefit (vertical) and Quantity of Housing (horizontal) [1]
Downward-sloping Marginal Private Benefit (MPB) curve and upward-sloping Marginal Private Cost (MPC) curve, with private market equilibrium (Qp, Pp) [0.5]
Marginal Social Benefit (MSB) curve drawn above/to the right of MPB, reflecting positive externalities [1]
Socially optimal equilibrium (Qs, Ps) shown at a higher quantity than Qp, with deadweight loss triangle identified [0.5]

Explanation (3 marks): In a free market, consumers make housing decisions based on their private benefits (MPB) and private costs (MPC), resulting in consumption at Qp [1]. However, housing generates positive externalities (health, education, social stability benefits to third parties), meaning the marginal social benefit (MSB) exceeds the marginal private benefit (MPB) [1]. The socially optimal level of consumption is Qs, where MSB = MPC. Since Qp < Qs, the free market results in under-consumption of housing, representing a market failure and a deadweight loss to society [1].

Marking notes:

Award up to [3] for the diagram (axes, curves, equilibria, deadweight loss)
Award up to [3] for the explanation (private vs. social benefit, under-consumption, deadweight loss)
Explanation must reference positive externalities
Accept diagrams with MSC/MSB framework

Section C: Evaluation (Questions 13–15)

Question 13 [10 marks]

Answer guidance:

Candidates should provide a balanced evaluation comparing demand-side and supply-side measures in addressing housing affordability.

Demand-side measures (ABSD and LTV limits):

ABSD increases transaction costs, reducing speculative and investment demand
LTV limits constrain borrowing capacity, reducing effective demand
These measures can be implemented quickly and have immediate effects on demand
Evidence from Table 1: HDB Resale Price Index declined from 100.0 (2015) to 97.8 (2018) following the July 2018 cooling measures
However, demand-side measures may disproportionately affect genuine homebuyers (e.g., first-time buyers facing higher downpayments)
Demand-side measures do not address the fundamental supply shortage

Supply-side measures (increased GLS supply):

Increasing land supply enables more housing units to be built, addressing the root cause of price increases
Supply-side measures have longer-lasting effects on affordability
However, supply responses are slow (4–5 year construction time lags as per Extract 3)
Supply-side measures are constrained by labour shortages and rising construction costs
The 25% increase in GLS supply may be insufficient given strong demand

Evaluation criteria:

Effectiveness in short run vs. long run
Impact on different segments of the market (HDB vs. private, first-time buyers vs. investors)
Interaction between demand-side and supply-side measures
Consideration of unintended consequences

Marking bands:

L3 (8–10 marks): Balanced evaluation with clear comparison of effectiveness, supported by data/extracts, with a justified conclusion on which type of measure is more effective and under what circumstances
L2 (5–7 marks): Good analysis of both types of measures with some evaluation, but may lack balance or depth in comparison
L1 (1–4 marks): Descriptive answer focusing on only one type of measure, or listing measures without evaluation

Question 14 [10 marks]

Answer guidance:

Candidates should evaluate the success of government intervention using evidence from the data and extracts.

Evidence of success in achieving affordability:

HDB Home Price-to-Income Ratio remained relatively stable (4.5 to 5.3) compared to Private ratio (9.8 to 11.9), suggesting HDB policies maintained affordability for public housing
80% of resident population lives in HDB flats with 90% home ownership (Extract 2)
Housing grants of up to SGD 80,000 for first-time buyers support affordability
Cooling measures moderated price increases after 2018 (Table 1 shows HDB index declined 2015–2018)

Evidence of success in achieving market stability:

Cooling measures prevented a property bubble (no sharp crashes observed)
Gradual price increases rather than volatile swings (Table 1)
Mortgage Servicing Ratio remained manageable (below 30% throughout)

Limitations and challenges:

Private property prices rose sharply (136.2 in 2023 from 100.0 in 2015) despite multiple rounds of cooling measures
Mortgage Servicing Ratio increased from 22.0% to 27.2%, indicating growing household debt burden
Construction delays (4–5 year waiting times) suggest supply-side policies have been less effective
Rising Home Price-to-Income Ratio for HDB (4.5 to 5.3) indicates gradual erosion of affordability
Critics' arguments about market distortions (Extract 2)

Evaluation criteria:

Balance between affordability and stability objectives
Differential impact on HDB vs. private markets
Short-term vs. long-term effectiveness
Consideration of trade-offs between intervention and market efficiency

Marking bands:

L3 (8–10 marks): Comprehensive evaluation using data and extracts, balanced assessment of both objectives, justified conclusion on overall success
L2 (5–7 marks): Good analysis with some evaluation, references to data but may lack balance or depth
L1 (1–4 marks): Descriptive or one-sided answer, limited use of evidence

Question 15 [10 marks]

Answer guidance:

Candidates should evaluate whether positive externalities are the main justification for government intervention in Singapore's housing market.

Arguments supporting positive externalities as the main justification:

Housing generates significant positive externalities: health, education, social stability (Extract 2)
Market failure from under-consumption justifies intervention to achieve socially optimal level
Without intervention, lower-income households would be unable to access adequate housing
The scale of intervention (80% of population in HDB) reflects the magnitude of external benefits

Arguments for other justifications:

Equity considerations: Housing is a basic necessity; intervention ensures equitable access regardless of income (reference to housing grants)
Merit good characteristics: Information failure — individuals may undervalue long-term benefits of adequate housing
Macroeconomic stability: Property market stability is crucial for financial system stability and household wealth
Social cohesion: HDB ethnic integration policies promote racial harmony (unique Singapore context)
Political and social objectives: Home ownership as a national goal, nation-building

Evaluation:

Positive externalities provide the economic efficiency justification, but equity and social objectives may be equally or more important in Singapore's context
The government's approach combines multiple objectives (affordability, stability, social cohesion)
The relative importance of different justifications may vary across different housing policies (e.g., BTO subsidies vs. cooling measures)

Marking bands:

L3 (8–10 marks): Thorough evaluation of multiple justifications, clear comparison of their relative importance, justified conclusion on whether positive externalities are the main justification
L2 (5–7 marks): Good discussion of positive externalities and at least one other justification, some evaluation but may lack depth
L1 (1–4 marks): Descriptive answer focusing mainly on positive externalities without considering alternatives

CASE STUDY 2: SINGAPORE'S LABOUR MARKET — CHALLENGES AND POLICY RESPONSES

Section A: Data Interpretation (Questions 16–20)

Question 16 [2 marks]

Answer: Singapore's overall unemployment rate increased from 1.9% in 2015 to a peak of 3.0% in 2020 [1], before declining to 1.9% in 2023, returning to the 2015 level [1].

Marking notes:

Award [1] for identifying the increase to peak in 2020
Award [1] for identifying the subsequent decline to 1.9% in 2023
Accept description of the trend with reference to specific data points

Question 17 [2 marks]

Answer: The resident unemployment rate was consistently higher than the overall unemployment rate throughout the period 2015 to 2023 [1]. For example, in 2020, the resident unemployment rate was 4.1% compared to the overall rate of 3.0%, a difference of 1.1 percentage points [1].

Marking notes:

Award [1] for noting that resident rate is consistently higher
Award [1] for supporting with data (any year comparison accepted)
Accept observation that both rates followed similar trends (peaked in 2020, declined thereafter)

Question 18 [2 marks]

Answer: The Construction sector experienced the largest absolute decline in employment [1], falling from 318,000 in 2015 to 285,000 in 2023, a decrease of 33,000 workers [1].

Marking notes:

Award [1] for correctly identifying the Construction sector
Award [1] for stating the magnitude (33,000 or 10.4%)
Accept Accommodation & Food Services if candidate notes it had the largest percentage decline, but Construction had the largest absolute decline

Question 19 [2 marks]

Answer: The Information & Communications sector experienced strong employment growth of 17.9% (from 168,000 to 198,000) [1], while the Accommodation & Food Services sector experienced a decline of 10.6% (from 218,000 to 195,000), indicating divergent trends between the two sectors [1].

Marking notes:

Award [1] for identifying growth in Information & Communications
Award [1] for identifying decline in Accommodation & Food Services
Accept comparative language ("whereas," "in contrast," "while")

Question 20 [2 marks]

Answer: In 2020, the unemployment rate increased to 3.0% (from 2.3% in 2019) while real income growth turned negative at -0.6% [1]. This inverse relationship suggests that the economic downturn caused by the COVID-19 pandemic led to both higher unemployment and falling real incomes [1].

Marking notes:

Award [1] for identifying the inverse relationship (unemployment up, income growth down/negative)
Award [1] for providing a brief explanation or linking to economic conditions
Accept reference to the pandemic context

Section B: Analysis and Application (Questions 21–27)

Question 21 [3 marks]

Answer: Structural unemployment refers to unemployment arising from a mismatch between the skills possessed by workers and the skills demanded by employers, often due to changes in the structure of the economy such as technological advancement or shifts in industry composition [1].

Cause in Singapore (2 marks): One cause of structural unemployment in Singapore is technological advancement and automation [1]. As stated in Extract 4, approximately 30% of jobs in Singapore are at high risk of displacement due to automation and digitalisation by 2030. Workers in sectors such as retail and manufacturing may lack the digital and technological skills required for new job roles, leading to structural unemployment [1].

Marking notes:

Award [1] for defining structural unemployment (mismatch of skills, long-term nature)
Award [1] for identifying a cause from Extract 4
Award [1] for explaining how the cause leads to structural unemployment
Accept other causes mentioned in Extract 4 (e.g., sectoral shifts)

Question 22 [4 marks]

Answer: The SkillsFuture initiative addresses skills mismatch by providing Singaporeans with credits (SGD 500, with additional top-ups) for approved training courses [1]. This reduces the financial barrier to skills upgrading, encouraging workers to acquire new competencies that are in demand [1]. By facilitating lifelong learning, SkillsFuture enables workers in declining sectors (e.g., retail, administrative support) to retrain for growth sectors such as ICT, where there were over 15,000 unfilled positions in 2023 [1]. This helps to reduce the mismatch between the skills workers possess and the skills employers require, thereby reducing structural unemployment [1].

Marking notes:

Award [1] for describing the SkillsFuture mechanism (credits for training)
Award [1] for explaining how it reduces financial barriers
Award [1] for linking to skills acquisition in growth sectors
Award [1] for explaining how this reduces skills mismatch/structural unemployment
Answers must reference Extract 4

Question 23 [4 marks]

Answer: The reduction in the Dependency Ratio Ceiling (DRC) for the services sector from 40% to 35% (and further to 31.5%) limits the proportion of foreign workers that firms can employ [1]. This reduces the supply of foreign labour available to firms in the services sector [1]. With fewer foreign workers available, firms may need to hire more local workers to maintain operations, potentially increasing the demand for local labour [1]. This could lead to higher wages and improved employment opportunities for local workers in the services sector, although firms may also face higher labour costs [1].

Marking notes:

Award [1] for explaining the DRC reduction (limits foreign worker proportion)
Award [1] for explaining the effect on foreign labour supply
Award [1] for explaining the effect on demand for local workers
Award [1] for explaining the wage/employment implications for local workers
Accept discussion of potential negative effects (higher costs, reduced competitiveness)

Question 24 [6 marks]

Answer:

Diagram (3 marks):

Correctly labelled axes: Wage Rate (vertical) and Quantity of Local Workers (horizontal) [1]
Initial demand curve for local labour (D1) and supply curve for local labour (S1), with equilibrium (W1, Q1) [0.5]
Rightward shift of demand curve for local labour from D1 to D2 (as firms substitute local for foreign workers) [1]
New equilibrium (W2, Q2) showing higher wage rate and higher employment level for local workers [0.5]

Explanation (3 marks): The tightening of foreign worker quotas reduces the availability of foreign labour, which is a substitute for local labour in production [1]. As firms face constraints on hiring foreign workers, they increase their demand for local workers to maintain production levels, shifting the demand curve for local labour rightward from D1 to D2 [1]. This leads to an increase in the equilibrium wage rate (from W1 to W2) and an increase in the equilibrium employment level (from Q1 to Q2) for local workers in the services sector, ceteris paribus [1].

Marking notes:

Award up to [3] for the diagram (axes, curves, shift, equilibrium changes)
Award up to [3] for the explanation (substitution effect, demand shift, wage and employment effects)
Explanation must reference the services sector and foreign worker quotas
Accept discussion of potential supply-side effects on local workers

Question 25 [4 marks]

Answer: The Jobs Support Scheme (JSS) functioned as an expansionary fiscal policy measure by providing government-funded wage subsidies to employers [1]. This represented an increase in government expenditure (totalling SGD 28 billion), which is a component of expansionary fiscal policy [1]. The wage subsidies reduced the cost of retaining workers for firms, enabling them to maintain employment levels despite reduced revenues during the pandemic [1]. By supporting household incomes, the JSS also helped to sustain consumption expenditure, preventing a deeper contraction in aggregate demand and supporting overall economic activity [1].

Marking notes:

Award [1] for identifying JSS as government expenditure/wage subsidies
Award [1] for linking to expansionary fiscal policy (increased G)
Award [1] for explaining the employment retention mechanism
Award [1] for explaining the aggregate demand/consumption effect
Answers must reference Extract 6

Question 26 [3 marks]

Answer: Opportunity cost refers to the value of the next best alternative foregone when a choice is made [1]. By providing SGD 28 billion in JSS wage subsidies, the Singapore government had to forego other potential uses of these funds [1]. One possible effect is that the government may have had to reduce spending on other areas such as healthcare, education, or infrastructure, or alternatively, increase borrowing (leading to higher future debt servicing costs) or raise taxes (reducing disposable incomes) [1].

Marking notes:

Award [1] for defining opportunity cost
Award [1] for applying the concept to the JSS expenditure
Award [1] for identifying a specific effect (reduced spending elsewhere, increased borrowing, higher taxes)
Accept any valid opportunity cost effect

Question 27 [4 marks]

Answer: Consequence 1: Positive effect on material living standards [1] The government stimulus, including the JSS, supported employment and household incomes during the pandemic. By preventing widespread job losses, the stimulus helped to maintain workers' ability to purchase goods and services, thereby supporting material living standards [1].

Consequence 2: Potential negative effect on future living standards [1] The unprecedented stimulus was financed through government borrowing, drawing on past reserves. This may necessitate higher taxes or reduced government spending in the future to restore fiscal sustainability, which could reduce future disposable incomes and material living standards [1].

Marking notes:

Award [1] for each identified consequence (maximum 2 marks)
Award [1] for each valid explanation (maximum 2 marks)
Accept other valid consequences (e.g., inflationary pressures reducing real purchasing power, improved non-material living standards through job security)
Consequences should be distinct

Section C: Evaluation (Questions 28–30)

Question 28 [10 marks]

Answer guidance:

Candidates should provide a balanced evaluation comparing supply-side policies and fiscal policy measures in addressing Singapore's long-term labour market challenges.

Supply-side policies (SkillsFuture and foreign worker quota tightening):

SkillsFuture addresses the root cause of structural unemployment by improving worker skills and adaptability
Foreign worker quota tightening encourages productivity improvements and reduces reliance on low-cost labour
These policies have long-term effects on the productive capacity of the economy
Evidence: Employment growth in high-skill sectors (ICT +17.9%, Professional Services +16.9% from Table 4)
However, supply-side policies take time to show results; skills upgrading requires years
Foreign worker tightening may cause short-term labour shortages and higher costs for businesses (67% of SMEs faced hiring difficulties per Extract 5)

Fiscal policy measures (Jobs Support Scheme):

JSS provided immediate support during the COVID-19 crisis, preventing mass unemployment
Fiscal measures can be targeted and adjusted quickly in response to economic conditions
Evidence: Resident unemployment fell from 4.1% (2020) to 2.6% (2023) following fiscal support
However, fiscal measures are short-term and do not address structural issues
Large fiscal expenditure (SGD 28 billion) creates opportunity costs and potential long-term fiscal burden
Fiscal measures may create dependency and delay necessary structural adjustments

Evaluation criteria:

Short-run vs. long-run effectiveness
Cyclical vs. structural challenges
Complementarity between supply-side and fiscal policies
Sustainability and fiscal constraints

Marking bands:

L3 (8–10 marks): Balanced evaluation with clear comparison, supported by data/extracts, justified conclusion on relative effectiveness for long-term challenges
L2 (5–7 marks): Good analysis of both policy types with some evaluation, but may lack depth in comparison
L1 (1–4 marks): Descriptive or one-sided answer, limited use of evidence

Question 29 [10 marks]

Answer guidance:

Candidates should evaluate the effectiveness of Singapore's labour market policies using evidence from the data and extracts.

Evidence of effectiveness in achieving low unemployment:

Overall unemployment rate returned to 1.9% in 2023 (from 3.0% in 2020) — Table 3
Resident unemployment rate declined from 4.1% (2020) to 2.6% (2023)
JSS supported employment retention during the pandemic (Extract 6)
SkillsFuture and training programmes facilitated workforce adaptation

Evidence of effectiveness in maintaining income growth:

Median monthly income increased from SGD 3,949 (2015) to SGD 5,197 (2023) — Table 3
Real income growth was positive in most years (except 2020)
Progressive Wage Model supported income growth for lower-wage workers (Extract 6)

Limitations and challenges:

Real income growth has been modest (2.1% in 2023) and below pre-pandemic levels
Structural unemployment and skills mismatch persist (98,000 vacancies alongside 65,000 unemployed — Extract 4)
Some sectors experienced employment decline (Construction -10.4%, Accommodation & Food Services -10.6% — Table 4)
SMEs face labour shortages and rising costs due to foreign worker policy tightening (Extract 5)
Income growth may be partly due to tight labour market rather than productivity improvements

Evaluation criteria:

Trade-offs between low unemployment and income growth
Differential impact across sectors and worker groups
Sustainability of current policies
Comparison with alternative policy approaches

Marking bands:

L3 (8–10 marks): Comprehensive evaluation using data and extracts, balanced assessment of both objectives, justified conclusion
L2 (5–7 marks): Good analysis with some evaluation, references to data but may lack balance
L1 (1–4 marks): Descriptive or one-sided answer, limited use of evidence

Question 30 [10 marks]

Answer guidance:

Candidates should evaluate whether structural or cyclical unemployment represents the greater challenge for Singapore's labour market.

Arguments that structural unemployment is the greater challenge:

Long-term nature: Structural unemployment persists even when the economy is at full employment
Technological disruption: 30% of jobs at high risk of displacement by 2030 (Extract 4)
Skills mismatch: 98,000 vacancies alongside 65,000 unemployed suggests structural issues (Extract 4)
Sectoral shifts: Employment declining in some sectors (Construction, Accommodation & Food Services) while growing in others (ICT, Professional Services) — Table 4
Structural unemployment requires complex, long-term solutions (education, training, industrial policy)
Demographic changes (ageing workforce) may exacerbate structural mismatches

Arguments that cyclical unemployment remains a significant challenge:

Singapore's open economy is vulnerable to external shocks (global recessions, trade disruptions)
COVID-19 demonstrated how quickly cyclical unemployment can rise (3.0% in 2020 from 2.3% in 2019)
Cyclical unemployment can become structural if prolonged (hysteresis effects)
Fiscal resources required to address cyclical unemployment are substantial (SGD 28 billion for JSS)
Global economic uncertainties (geopolitical tensions, supply chain disruptions) increase cyclical risks

Evaluation:

Both types of unemployment are interconnected; cyclical unemployment can become structural
The relative importance depends on the time horizon (structural more important in long run, cyclical in short run)
Singapore's policy mix addresses both (SkillsFuture for structural, JSS for cyclical)
Structural unemployment may be the greater challenge because it persists even during economic expansions and requires fundamental changes to the workforce

Marking bands:

L3 (8–10 marks): Thorough evaluation of both types of unemployment, clear comparison of their relative significance, justified conclusion supported by evidence
L2 (5–7 marks): Good discussion of both types with some evaluation, but may lack depth in comparison
L1 (1–4 marks): Descriptive or one-sided answer, limited use of evidence
