Case Study 1: The Global Semiconductor Market and Singapore's Position

Total Marks: 50

Context

Semiconductors are essential components in electronic devices ranging from smartphones to electric vehicles. The global semiconductor industry has experienced significant fluctuations in demand and supply over the past decade. Singapore plays a key role as a major semiconductor manufacturing hub, accounting for approximately 11% of global semiconductor output.

Extract 1: Semiconductor Industry Dynamics

The semiconductor industry is characterised by high fixed costs and significant economies of scale. Building a state-of-the-art fabrication plant ("fab") costs between US $10 billion and US$ 20 billion. Once built, the marginal cost of producing each additional chip is relatively low. This cost structure creates substantial barriers to entry.

Demand for semiconductors is derived from demand for end-products such as smartphones, computers, and automobiles. During the COVID-19 pandemic, demand for consumer electronics surged as people worked and studied from home. However, supply chain disruptions limited production capacity, leading to a global chip shortage in 2020–2021. By 2023, demand had moderated while new production capacity came online, resulting in an oversupply in some chip segments.

The price elasticity of demand for semiconductors varies by segment. Memory chips, which are relatively standardised, tend to have more elastic demand. Advanced logic chips, used in specific applications with few substitutes, tend to have more inelastic demand. The price elasticity of supply is generally inelastic in the short run due to the long lead times required to build new fabrication facilities, but becomes more elastic in the long run.

Extract 2: Singapore's Semiconductor Strategy

Singapore's semiconductor industry contributes approximately 7% of the country's GDP and employs over 35,000 workers. The government has identified semiconductors as a strategic growth sector under its Research, Innovation and Enterprise (RIE) 2025 plan.

In 2023, the Singapore government announced a S$3 billion top-up to the Research, Innovation and Enterprise fund, with a significant portion allocated to semiconductor research and development. The Economic Development Board (EDB) offers tax incentives and grants to attract semiconductor companies to establish or expand operations in Singapore.

However, Singapore faces challenges. The industry is highly capital-intensive, and competition from Taiwan and South Korea is intense. Singapore's higher labour and utility costs (see Table 2) put it at a cost disadvantage. Additionally, the industry's cyclical nature means that periods of oversupply can lead to falling prices and reduced profitability.

A government report noted: "Singapore must move up the value chain, focusing on higher-value activities such as chip design, research and development, and advanced packaging, rather than competing solely on manufacturing cost."

Extract 3: Environmental Considerations

Semiconductor manufacturing is resource-intensive. A single fabrication plant can use between 2 million and 4 million gallons of water per day. The industry also generates hazardous waste and contributes to greenhouse gas emissions through high electricity consumption.

In Singapore, semiconductor firms are subject to environmental regulations, including water recycling requirements and emissions standards. The government has encouraged the adoption of sustainable manufacturing practices through grants and incentives. However, compliance with environmental regulations increases production costs, which may affect Singapore's competitiveness relative to countries with less stringent environmental standards.

Case Study 2: Housing Affordability and Government Intervention in Singapore

Total Marks: 50

Context

Housing is a fundamental need, and in Singapore, the government plays a dominant role in the housing market through the Housing and Development Board (HDB). Approximately 80% of Singapore's resident population lives in HDB flats. However, rising property prices in both the public and private housing markets have raised concerns about housing affordability, particularly for younger Singaporeans.

Year	HDB Resale Price Index	Private Residential Price Index	Median Household Income Index (2015 = 100)
2015	100.0	100.0	100.0

Extract 4: The Singapore Housing Model

Singapore's housing model is unique. The HDB develops and sells public housing flats to eligible Singaporean households at subsidised prices. First-time buyers of new HDB flats receive significant housing grants, with additional grants for lower-income households and those purchasing flats near their parents.

The government regulates the housing market through various measures. On the supply side, the government controls land supply through the Government Land Sales (GLS) programme. On the demand side, cooling measures such as the Additional Buyer's Stamp Duty (ABSD) and Loan-to-Value (LTV) limits have been implemented to moderate demand, particularly from investors and foreign buyers.

A government spokesperson stated: "Our housing policies aim to ensure that public housing remains affordable and accessible to Singaporeans, while maintaining a stable and sustainable property market."

Extract 5: Market Failure in Housing

Housing markets are prone to market failures. Information asymmetry exists between property developers and buyers regarding construction quality and future market conditions. The housing market also exhibits characteristics of merit goods—society benefits when citizens have access to adequate housing, beyond the private benefits to individual homeowners.

Furthermore, housing generates externalities. Well-maintained public housing estates create positive externalities in the form of community cohesion and social stability. Conversely, housing shortages and overcrowding can generate negative externalities such as social problems and reduced quality of life.

Without government intervention, the free market may under-provide affordable housing. Private developers have incentives to build higher-end properties that generate greater profits, potentially leaving a gap in the provision of affordable housing for lower and middle-income households.

Extract 6: Recent Policy Responses

In response to rising housing prices, the Singapore government introduced a series of cooling measures in 2022 and 2023:

Increased ABSD rates: The ABSD for foreign buyers was raised from 30% to 60%. For Singapore citizens purchasing their second residential property, the ABSD was increased from 12% to 20%.
Tighter LTV limits: The LTV limit for HDB housing loans was reduced from 85% to 80%, requiring buyers to make larger down payments.
Increased housing supply: The government announced plans to launch up to 23,000 new HDB flats per year in 2023 and 2024, up from an average of 17,000 per year between 2018 and 2022.
Enhanced housing grants: The Enhanced CPF Housing Grant (EHG) was increased, providing up to S $80,000 for eligible first-time buyers of new and resale flats, up from the previous maximum of S$ 50,000.

These measures have had some effect. The HDB resale price index growth slowed from 12.7% in 2021 to 2.9% in 2023. However, critics argue that the measures have made it harder for young couples to purchase their first home due to larger down payment requirements, and that the increased supply of new flats will take several years to materialise.

Case Study 1: The Global Semiconductor Market and Singapore's Position

Section A: Data Interpretation and Analysis [14 marks]

Question 1 [4 marks] With reference to Table 1, compare the trend in global semiconductor revenue with the trend in unit shipments from 2018 to 2023.

Answer: Both global semiconductor revenue and unit shipments showed an overall increase from 2018 to 2023, but with different patterns. Revenue fell from US $468.8 billion in 2018 to US$ 412.3 billion in 2019 [1 mark], while unit shipments also fell from 1,045.2 billion to 976.8 billion over the same period [1 mark]. Both revenue and unit shipments then rose to peaks in 2021–2022, with revenue peaking at US $573.5 billion in 2022 and unit shipments peaking at 1,147.2 billion in 2021 [1 mark]. However, between 2022 and 2023, revenue fell more sharply (from US$ 573.5 billion to US$520.1 billion, a 9.3% decline) compared to unit shipments (from 1,089.3 billion to 1,002.4 billion, an 8.0% decline), suggesting that the average selling price also contributed to the revenue decline [1 mark].

Marking notes:

1 mark: Identifies the initial decline in both variables (2018–2019)
1 mark: Identifies the recovery and peak period (2019–2021/2022)
1 mark: Notes the subsequent decline (2022–2023)
1 mark: Provides comparative insight (e.g., different rates of change, revenue falling more sharply than shipments)
Accept any reasonable comparative observation supported by data

Question 2 [4 marks] Using Table 2, compare Singapore's cost competitiveness in semiconductor manufacturing with that of Taiwan.

Answer: Singapore has higher costs than Taiwan across all four indicators shown [1 mark]. Singapore's labour cost per hour (US $18.50) is 50.4% higher than Taiwan's (US$ 12.30) [1 mark]. Singapore's electricity cost (US $0.14/kWh) is 55.6% higher than Taiwan's (US$ 0.09/kWh), and water cost (US $2.10/m³) is 147% higher than Taiwan's (US$ 0.85/m³) [1 mark]. However, Singapore's corporate tax rate (17.0%) is lower than Taiwan's (20.0%), which partially offsets the higher operating costs [1 mark].

Marking notes:

1 mark: Overall comparative statement (Singapore generally higher cost)
1 mark: Specific comparison of labour costs with data
1 mark: Specific comparison of utility costs (electricity and/or water) with data
1 mark: Notes the tax rate advantage as a mitigating factor
Award marks for any two specific cost comparisons with data reference

Question 3 [2 marks] With reference to Table 1, calculate the percentage change in the average selling price of semiconductors between 2018 and 2022.

Answer: Average selling price in 2018: US $0.45 Average selling price in 2022: US$ 0.53 Percentage change = [(0.53 − 0.45) / 0.45] × 100 = (0.08 / 0.45) × 100 = 17.8% increase [2 marks]

Marking notes:

1 mark: Correct formula and substitution
1 mark: Correct answer (17.8% or 17.78%)
Accept 17.8% or 18% (rounded)
Award 1 mark only if formula is correct but calculation error made

Question 4 [4 marks] Using Table 1, describe the relationship between unit shipments and average selling price between 2020 and 2022.

Answer: Between 2020 and 2021, both unit shipments and average selling price increased. Unit shipments rose from 1,001.5 billion to 1,147.2 billion (a 14.5% increase), while the average selling price rose from US $0.44 to US$ 0.48 (a 9.1% increase) [1 mark]. This indicates that both quantity and price were rising simultaneously, suggesting strong demand growth outpacing supply [1 mark]. Between 2021 and 2022, unit shipments fell from 1,147.2 billion to 1,089.3 billion (a 5.0% decrease), while the average selling price continued to rise from US $0.48 to US$ 0.53 (a 10.4% increase) [1 mark]. This inverse relationship suggests that supply constraints or shifts in product mix toward higher-value chips may have driven prices higher despite falling volumes [1 mark].

Marking notes:

1 mark: Describes the 2020–2021 period (both increasing)
1 mark: Explains the implication (strong demand)
1 mark: Describes the 2021–2022 period (inverse relationship)
1 mark: Explains the implication (supply constraints or product mix effects)
Accept alternative reasonable interpretations supported by data

Section B: Economic Analysis [20 marks]

Question 5 [6 marks] Using a demand and supply diagram, explain how the events described in Extract 1 (surging demand and supply chain disruptions during 2020–2021) would have affected the equilibrium price and quantity of semiconductors.

Answer: The surge in demand for consumer electronics during the pandemic caused the demand curve for semiconductors to shift rightward from D1 to D2 [1 mark]. Simultaneously, supply chain disruptions limited production capacity, causing the supply curve to shift leftward from S1 to S2 [1 mark]. The diagram should show both curves shifting, with the demand curve shifting right and the supply curve shifting left [1 mark]. The combined effect is an unambiguous increase in equilibrium price from P1 to P2, as both the demand increase and supply decrease put upward pressure on price [1 mark]. The effect on equilibrium quantity is indeterminate in theory—the demand increase tends to increase quantity while the supply decrease tends to reduce quantity [1 mark]. However, Table 1 shows that unit shipments increased from 976.8 billion in 2019 to 1,147.2 billion in 2021, indicating that the demand shift was larger in magnitude than the supply shift, resulting in a net increase in equilibrium quantity [1 mark].

Marking notes:

1 mark: Correct rightward demand shift with explanation
1 mark: Correct leftward supply shift with explanation
1 mark: Accurate diagram with both shifts, labelled axes (Price, Quantity), and equilibrium points
1 mark: Clear explanation of price effect (unambiguous increase)
1 mark: Recognition that quantity effect is theoretically indeterminate
1 mark: Resolution using data evidence (quantity increased, so demand shift dominated)
Maximum 4 marks without diagram

Question 6 [4 marks] With reference to Extract 1, explain why the price elasticity of supply for semiconductors is likely to be inelastic in the short run but more elastic in the long run.

Answer: In the short run, PES for semiconductors is inelastic because production capacity is fixed. Building a new fabrication plant costs US$10–20 billion and takes several years, as stated in Extract 1 [1 mark]. Firms cannot quickly increase output in response to price changes because they are constrained by existing capacity [1 mark]. In the long run, PES becomes more elastic because firms can build new fabrication facilities, expand existing plants, and install additional equipment [1 mark]. The longer time horizon allows firms to adjust all factors of production, making supply more responsive to price changes. Extract 1 notes that "new production capacity came online" by 2023, illustrating this long-run adjustment [1 mark].

Marking notes:

1 mark: Identifies capacity constraints as reason for short-run inelasticity
1 mark: Links to extract evidence (high fixed costs, long build times)
1 mark: Explains long-run adjustment (new capacity, all factors variable)
1 mark: Links to extract evidence or provides clear reasoning
Accept reference to other relevant factors: specialised equipment, skilled labour availability, regulatory approvals

Question 7 [4 marks] Using the concept of opportunity cost, explain one possible effect on the Singapore government arising from its decision to allocate S$3 billion to semiconductor research and development.

Answer: Opportunity cost is the value of the next-best alternative foregone when a choice is made [1 mark]. By allocating S $3 billion to semiconductor R&D, the Singapore government foregoes the benefits that could have been derived from using that S$ 3 billion for other purposes [1 mark]. One possible effect is that the government may have to reduce spending on other areas such as healthcare, education, or infrastructure, potentially affecting the quality or availability of these public services [1 mark]. Alternatively, the government may need to raise taxes or increase borrowing to fund the semiconductor R&D without cutting other spending, which could reduce households' disposable income or increase future debt servicing obligations [1 mark].

Marking notes:

1 mark: Correct definition of opportunity cost
1 mark: Application of concept to the S$3 billion allocation
1 mark: Identification of a specific effect (reduced spending elsewhere OR increased taxation/borrowing)
1 mark: Explanation of the consequence of that effect
Accept any reasonable effect linked to opportunity cost

Question 8 [6 marks] With reference to Extract 1, explain how the price elasticity of demand for memory chips differs from that for advanced logic chips, and discuss the implications for a semiconductor firm's pricing strategy.

Answer: According to Extract 1, memory chips have more elastic demand because they are relatively standardised, meaning buyers can easily switch between suppliers if prices change [1 mark]. Advanced logic chips have more inelastic demand because they are used in specific applications with few substitutes, making buyers less responsive to price changes [1 mark].

For memory chips with elastic demand, a firm that raises prices will experience a more-than-proportionate fall in quantity demanded, leading to a decrease in total revenue [1 mark]. Therefore, firms producing memory chips should adopt a competitive pricing strategy, keeping prices low to maintain market share and volume [1 mark]. For advanced logic chips with inelastic demand, a firm that raises prices will experience a less-than-proportionate fall in quantity demanded, leading to an increase in total revenue [1 mark]. Therefore, firms producing advanced logic chips have greater pricing power and can charge premium prices to maximise revenue, particularly if they have proprietary technology or strong brand loyalty [1 mark].

Marking notes:

1 mark: Explains why memory chips have elastic demand (standardised, substitutes available)
1 mark: Explains why advanced logic chips have inelastic demand (specific applications, few substitutes)
1 mark: Correct revenue implication for elastic demand (price increase reduces revenue)
1 mark: Correct pricing strategy for elastic demand (competitive/low pricing)
1 mark: Correct revenue implication for inelastic demand (price increase raises revenue)
1 mark: Correct pricing strategy for inelastic demand (premium pricing)
Award marks for clear linkage between elasticity and pricing strategy

Section C: Evaluation and Policy Discussion [16 marks]

Question 9 [8 marks] Discuss the extent to which Singapore's higher labour and utility costs (Table 2) are likely to reduce its comparative advantage in semiconductor manufacturing.

Answer: Singapore's higher labour and utility costs compared to Taiwan, South Korea, and China (Table 2) increase the cost of production for semiconductor manufacturing in Singapore [1 mark]. Higher production costs mean that Singapore firms must charge higher prices to maintain profitability, which could reduce Singapore's price competitiveness in the global semiconductor market [1 mark]. This erodes Singapore's comparative advantage if cost is the primary basis of competition [1 mark].

However, several factors may mitigate the impact of higher costs on Singapore's comparative advantage [1 mark]. First, Singapore's lower corporate tax rate (17%) compared to Taiwan (20%), South Korea (25%), and China (25%) partially offsets higher operating costs, improving after-tax profitability [1 mark]. Second, comparative advantage is determined by relative opportunity cost, not absolute cost. Singapore may have comparative advantage in higher-value semiconductor activities such as R&D and chip design, where labour productivity and innovation capabilities matter more than hourly labour costs [1 mark]. Third, Singapore's strong intellectual property protection, political stability, and skilled workforce create non-cost advantages that attract semiconductor investment despite higher costs [1 mark].

In conclusion, while higher costs do reduce Singapore's cost competitiveness in basic manufacturing, Singapore's comparative advantage increasingly lies in higher-value activities where cost is less important than technology, skills, and innovation. The extent of the impact depends on Singapore's ability to continue moving up the value chain [1 mark].

Marking notes:

1 mark: Identifies the cost disadvantage from Table 2 data
1 mark: Explains how higher costs affect price competitiveness
1 mark: Links to comparative advantage concept
1 mark: Identifies mitigating factors (balanced analysis)
Up to 3 marks: Development of mitigating factors (tax rate, value chain position, non-cost advantages)
1 mark: Reasoned conclusion addressing "extent"
Award up to 6 marks for one-sided analysis; full 8 marks requires balanced evaluation

Question 10 [8 marks] Evaluate the effectiveness of government subsidies and tax incentives (Extract 2) in addressing the challenges faced by Singapore's semiconductor industry.

Answer: Government subsidies and tax incentives can address several challenges faced by Singapore's semiconductor industry [1 mark]. The S$3 billion R&D fund (Extract 2) helps offset high fixed costs and encourages innovation, enabling firms to move up the value chain as recommended in the government report [1 mark]. Tax incentives reduce the effective tax burden, partially offsetting Singapore's higher labour and utility costs and improving the after-tax return on investment [1 mark]. These measures can attract and retain semiconductor investment in Singapore, supporting employment and GDP contribution [1 mark].

However, subsidies and tax incentives have limitations [1 mark]. They do not directly address the underlying cost disadvantages in labour and utilities, which are structural and may persist despite incentives [1 mark]. Subsidies represent an opportunity cost to the government; the S$3 billion could have been used for other priorities such as healthcare or education [1 mark]. There is also a risk that firms become dependent on government support, reducing the incentive to improve efficiency independently. Additionally, other countries can offer similar or larger incentives, potentially triggering a "subsidy race" that erodes the effectiveness of Singapore's measures [1 mark].

In conclusion, subsidies and tax incentives are partially effective in addressing the challenges. They are most effective when targeted at activities that build long-term competitive advantage, such as R&D and advanced manufacturing, rather than simply offsetting cost disadvantages. Their effectiveness depends on complementary policies, including skills development and infrastructure investment [1 mark].

Marking notes:

1 mark: Identifies how subsidies/incentives address challenges
Up to 3 marks: Development of arguments for effectiveness (R&D support, cost offset, investment attraction)
1 mark: Identifies limitations (balanced analysis)
Up to 3 marks: Development of limitations (structural costs, opportunity cost, dependency, subsidy race)
1 mark: Reasoned conclusion with conditions for effectiveness
Award up to 6 marks for one-sided analysis; full 8 marks requires balanced evaluation

Case Study 2: Housing Affordability and Government Intervention in Singapore

Section A: Data Interpretation and Analysis [14 marks]

Question 11 [4 marks] With reference to Table 3, compare the trends in the HDB Resale Price Index and the Private Residential Price Index from 2015 to 2023.

Answer: Both the HDB Resale Price Index and the Private Residential Price Index showed an overall increase from 2015 to 2023, but with different patterns [1 mark]. The HDB Resale Price Index was relatively stable between 2015 and 2019, fluctuating within a narrow range of 98.0 to 100.0, before rising sharply from 2020 onwards to reach 118.3 in 2023 [1 mark]. In contrast, the Private Residential Price Index fell initially from 100.0 in 2015 to 97.0 in 2016, then recovered and rose steadily from 2017 onwards, reaching 128.0 in 2023 [1 mark]. The Private Residential Price Index increased by a larger magnitude overall (28.0 points, or 28%) compared to the HDB Resale Price Index (18.3 points, or 18.3%), indicating that private property prices rose faster than HDB resale prices over the period [1 mark].

Marking notes:

1 mark: Overall comparative statement (both increased, different patterns)
1 mark: Describes HDB trend (stable then sharp rise post-2020)
1 mark: Describes private property trend (initial fall then steady rise)
1 mark: Compares magnitude of change with data
Accept any reasonable comparative observations supported by data

Question 12 [4 marks] Using Table 3, describe how the relationship between the HDB Resale Price Index and the Median Household Income Index changed between 2015 and 2023.

Answer: Between 2015 and 2019, the Median Household Income Index rose from 100.0 to 112.3 (a 12.3% increase), while the HDB Resale Price Index fell slightly from 100.0 to 98.5 (a 1.5% decrease) [1 mark]. This means that HDB flats became more affordable during this period, as incomes grew while HDB prices remained stable or declined [1 mark]. However, between 2019 and 2023, the HDB Resale Price Index rose sharply from 98.5 to 118.3 (a 20.1% increase), while the Median Household Income Index rose more slowly from 112.3 to 122.0 (an 8.6% increase) [1 mark]. This indicates that HDB prices grew faster than incomes in the later period, meaning that housing affordability deteriorated between 2019 and 2023 [1 mark].

Marking notes:

1 mark: Describes the 2015–2019 relationship (income rising faster than HDB prices)
1 mark: Explains the affordability implication (improving affordability)
1 mark: Describes the 2019–2023 relationship (HDB prices rising faster than income)
1 mark: Explains the affordability implication (deteriorating affordability)
Accept alternative reasonable interpretations supported by data

Question 13 [2 marks] With reference to Table 4, compare Singapore's housing affordability with that of Hong Kong.

Answer: Singapore's median home price to median household income ratio (5.2) is significantly lower than Hong Kong's (18.8) [1 mark], indicating that housing is much more affordable in Singapore relative to income. Singapore's home ownership rate (89.3%) is also substantially higher than Hong Kong's (51.0%), reflecting greater access to home ownership [1 mark].

Question 14 [4 marks] Using Table 4, identify and explain one advantage and one disadvantage of Singapore's high government housing provision rate.

Answer: Advantage: Singapore's high government housing provision rate (80%) contributes to its high home ownership rate (89.3%), which is the highest among the cities shown [1 mark]. Government provision ensures that housing is available at below-market prices, making home ownership accessible to a larger proportion of the population. This promotes social stability and a sense of rootedness among citizens [1 mark].

Disadvantage: High government housing provision requires substantial government expenditure on land acquisition, construction, and subsidies [1 mark]. This represents a significant opportunity cost, as government resources allocated to housing cannot be used for other priorities such as healthcare, education, or infrastructure. Additionally, a large public housing sector may crowd out private sector participation and reduce market efficiency [1 mark].

Section B: Economic Analysis [20 marks]

Question 15 [6 marks] Using a demand and supply diagram, explain how the cooling measures described in Extract 6 (increased ABSD and tighter LTV limits) would affect the equilibrium price and quantity in Singapore's private housing market.

Answer: The cooling measures—increased ABSD rates and tighter LTV limits—increase the cost of purchasing private property and reduce buyers' ability to borrow [1 mark]. These measures reduce the effective demand for private housing, causing the demand curve to shift leftward from D1 to D2 [1 mark]. The supply curve remains unchanged in the short run, as the measures target demand rather than supply [1 mark]. The diagram should show a leftward shift of the demand curve along a given supply curve [1 mark]. The new equilibrium occurs at a lower price (P1 to P2) and a lower quantity (Q1 to Q2) [1 mark]. This is consistent with the intended effect of cooling measures: to moderate price increases and reduce transaction volumes in the private housing market [1 mark].

Question 16 [4 marks] With reference to Extract 5, explain why housing may be considered a merit good and how this leads to market failure.

Answer: A merit good is a good that the government believes people should consume more of than they would choose to in a free market, because consumption generates positive externalities or because individuals undervalue the benefits [1 mark]. Housing may be considered a merit good because, as Extract 5 states, "society benefits when citizens have access to adequate housing, beyond the private benefits to individual homeowners" [1 mark]. These social benefits include community cohesion and social stability.

Market failure occurs because, in a free market, individuals consider only their private benefits when deciding how much housing to consume, ignoring the external benefits to society [1 mark]. This leads to under-consumption (or under-provision) of adequate housing relative to the socially optimal level. Without government intervention, private developers may focus on higher-end properties that generate greater profits, leaving a gap in affordable housing provision for lower and middle-income households [1 mark].

Question 17 [4 marks] Using the concept of price elasticity of supply, explain why the increased supply of new HDB flats (Extract 6) is unlikely to have an immediate effect on housing prices.

Answer: The price elasticity of supply measures the responsiveness of quantity supplied to a change in price [1 mark]. The supply of new HDB flats is highly price inelastic in the short run because housing construction takes several years from planning to completion [1 mark]. Even though the government announced plans to launch up to 23,000 new flats per year, these flats will take 3–5 years to build before they are ready for occupation [1 mark]. Therefore, the increase in planned supply does not immediately increase the available stock of housing. The supply curve remains effectively fixed in the short run, meaning that prices will not be affected until the new flats are completed and enter the market [1 mark].

Question 18 [6 marks] With reference to Extract 5, explain how positive externalities from well-maintained public housing estates can result in market failure.

Answer: Positive externalities occur when the consumption or production of a good generates benefits to third parties that are not reflected in the market price [1 mark]. Well-maintained public housing estates generate positive externalities in the form of community cohesion, social stability, and improved quality of life for residents and the wider community, as noted in Extract 5 [1 mark].

In a free market without government intervention, the provision of well-maintained housing would be determined by private benefits and private costs only [1 mark]. Individuals and private developers consider only their private benefits (e.g., personal satisfaction, rental income) and ignore the external benefits to society [1 mark]. This means the marginal social benefit (MSB) exceeds the marginal private benefit (MPB). The free market equilibrium occurs where MPB equals marginal private cost (MPC), resulting in a quantity (Qm) that is below the socially optimal quantity (Qs) where MSB equals marginal social cost (MSC) [1 mark]. This under-provision of well-maintained housing represents a market failure, as society would benefit from a higher level of housing quality and maintenance than the free market would provide [1 mark].

Section C: Evaluation and Policy Discussion [16 marks]

Question 19 [8 marks] Discuss whether the cooling measures described in Extract 6 are likely to be more effective than increasing housing supply in addressing housing affordability concerns in Singapore.

Answer: Cooling measures such as increased ABSD and tighter LTV limits (Extract 6) can be effective in the short run by immediately reducing demand pressure on housing prices [1 mark]. By making it more expensive for investors and foreign buyers to purchase property, and by requiring larger down payments, these measures directly reduce the quantity of housing demanded at any given price, leading to lower equilibrium prices [1 mark]. The evidence in Extract 6 shows that HDB resale price growth slowed from 12.7% in 2021 to 2.9% in 2023, suggesting some effectiveness [1 mark].

However, cooling measures have limitations. They do not address the fundamental supply-demand imbalance that drives long-term price increases [1 mark]. They may also have unintended consequences, such as making it harder for genuine first-time buyers to afford down payments, as critics noted in Extract 6 [1 mark]. Furthermore, cooling measures may need to be continually adjusted as market participants find ways to circumvent them.

Increasing housing supply addresses the root cause of rising prices—a shortage of housing relative to demand [1 mark]. By launching up to 23,000 new flats per year, the government increases the available stock of housing, which should reduce upward pressure on prices in the long run. However, as discussed in Question 17, supply increases take several years to materialise due to construction lags, making this approach less effective for immediate affordability concerns [1 mark].

In conclusion, cooling measures are likely to be more effective in the short run for quickly moderating price increases, while increasing housing supply is more effective for long-term affordability. The most effective approach is likely a combination of both: cooling measures to manage demand in the short term while increasing supply to address the fundamental imbalance over time [1 mark].

Question 20 [8 marks] Evaluate the extent to which government intervention in Singapore's housing market can be justified on the grounds of both equity and efficiency.

Answer: Government intervention in Singapore's housing market can be justified on equity grounds because housing is a basic need, and the free market may not provide affordable housing for lower-income households [1 mark]. Without intervention, private developers have incentives to build higher-end properties that generate greater profits (Extract 5), potentially excluding lower-income groups from adequate housing [1 mark]. Singapore's public housing programme, with its subsidies and grants for first-time buyers, promotes equity by ensuring that home ownership is accessible across income groups. Table 4 shows that Singapore achieves an 89.3% home ownership rate, the highest among the cities shown, demonstrating the equity outcomes of intervention [1 mark].

Government intervention can also be justified on efficiency grounds due to market failures in the housing market [1 mark]. As discussed in Question 18, housing generates positive externalities (community cohesion, social stability) that the free market does not account for, leading to under-provision [1 mark]. Information asymmetry between developers and buyers, and the merit good characteristics of housing, provide additional efficiency justifications for intervention [1 mark].

However, government intervention also has potential drawbacks. Subsidies and grants require substantial government expenditure, representing an opportunity cost (as noted in Question 14) [1 mark]. Extensive government involvement may crowd out private sector innovation and reduce market efficiency. There is also a risk of government failure if policies are poorly designed or implemented.

In conclusion, government intervention in Singapore's housing market can be strongly justified on both equity and efficiency grounds, given the market failures identified and the importance of housing as a basic need. The extent of justification is high, as evidenced by Singapore's success in achieving widespread home ownership and social stability. However, the form and degree of intervention should be continually evaluated to minimise unintended consequences and ensure efficient use of resources [1 mark].
