Section A: Data Response (Questions 1–5)

Question 1 [3 marks]

Answer: The resource curse refers to the paradox where countries with an abundance of natural resources (such as oil, gas, or minerals) tend to have less economic growth, less democracy, or worse development outcomes than countries with fewer natural resources. This can occur due to factors such as over-reliance on primary commodity exports, neglect of other sectors, corruption, and weak institutions.

Two symptoms evident in Country X:

1. Contraction of the manufacturing sector – Country X's manufacturing sector has contracted, and it now imports most of its consumer goods. This is a classic symptom of "Dutch disease," where resource booms appreciate the exchange rate and make other traded sectors uncompetitive.
2. Rising inequality – The Gini coefficient has risen from 0.38 to 0.52, indicating worsening income inequality despite GDP growth.
3. Weak institutions and corruption – The report notes poor enforcement of property rights and high levels of corruption, which are common features of the resource curse.

Marking Notes:

• 1 mark for a correct definition of the resource curse.
• 1 mark for each correctly identified symptom (max 2 marks).

Question 2 [4 marks]

Answer: The Capital Approach framework measures sustainable development by tracking changes in a country's total capital stock, which includes:

• Financial capital – savings, investments, and financial assets
• Produced capital – infrastructure, machinery, buildings
• Natural capital – natural resources, ecosystems, environmental services
• Human capital – education, skills, health of the population
• Social capital – institutions, trust, social cohesion

Analysis of Country X's growth:

• Country X's growth has been driven by extraction of natural capital (oil and rare earth minerals), which is being depleted.
• The revenue from resource extraction has not been sufficiently reinvested into produced capital (manufacturing has contracted) or human capital (HDI ranking has fallen).
• Social capital is weak, as evidenced by corruption and poor property rights enforcement.
• Therefore, while GDP has grown, the country's total capital stock may be declining, making its growth unsustainable. The current generation is consuming wealth that should be available for future generations.

Marking Notes:

• 1 mark for identifying the components of the Capital Approach.
• 2 marks for analysing how Country X's growth depletes capital.
• 1 mark for concluding that growth is unsustainable.

Question 3 [6 marks]

Answer: Dynamic comparative advantage refers to the idea that a country's comparative advantage can change over time due to factors such as technological progress, human capital development, and investment in infrastructure. Unlike static comparative advantage (based on current factor endowments), dynamic comparative advantage recognises that countries can develop new areas of competitive strength.

Evaluation of trade liberalisation for inclusive growth:

Arguments that it may promote inclusive growth:

• Trade liberalisation exposes domestic firms to international competition, incentivising innovation and efficiency improvements.
• It allows access to larger markets, enabling economies of scale in manufacturing.
• Imported capital goods and technology can enhance productivity.
• Export-oriented manufacturing can create jobs, particularly for low-skilled workers, reducing poverty.

Arguments that it may not promote inclusive growth:

• Country X's manufacturing sector is currently weak and may not be able to compete with established producers, leading to job losses in the short run.
• Without complementary policies (education, infrastructure, financial development), the benefits of liberalisation may accrue mainly to the resource sector and elites.
• The appreciation of the exchange rate due to resource exports (Dutch disease) may undermine the competitiveness of manufacturing even after liberalisation.
• Weak institutions and corruption may divert the gains from trade away from the poor.

Conclusion: Trade liberalisation alone is unlikely to promote inclusive growth. It must be accompanied by investment in human capital, infrastructure, and institutional reform to help the country develop new comparative advantages and ensure the gains from trade are widely shared.

Marking Notes:

• 1 mark for defining dynamic comparative advantage.
• 2 marks for arguments supporting trade liberalisation.
• 2 marks for counter-arguments.
• 1 mark for a reasoned conclusion.

Question 4 [6 marks]

Answer: Multinational enterprises (MNEs) are firms that operate in multiple countries through foreign direct investment (FDI). Their role in promoting sustainable development in Country X can be analysed as follows:

Potential benefits:

• Technology transfer – MNEs bring advanced technology and managerial expertise, which can improve productivity in the host country.
• Capital inflow – FDI provides much-needed capital for investment, supplementing domestic savings.
• Job creation – MNEs create employment opportunities, directly and through their supply chains.
• Human capital development – MNEs often provide training to local workers, enhancing their skills.
• Tax revenue – MNEs contribute to government revenue through corporate taxes, which can fund public services.
• Integration into global value chains – This can help the country diversify away from resource dependence.

Potential drawbacks:

• Profit repatriation – MNEs may repatriate profits to their home countries, reducing the net benefit to the host economy.
• Crowding out – MNEs may outcompete local firms, leading to a concentration of market power.
• Environmental degradation – MNEs may exploit weak environmental regulations, depleting natural capital.
• Transfer pricing – MNEs may manipulate prices to shift profits to low-tax jurisdictions, reducing tax revenue.
• Dependency – Over-reliance on MNEs can make the economy vulnerable to their decisions (e.g., relocating production).
• Limited linkages – If MNEs operate in enclaves with few links to the local economy, the spillover benefits may be limited.

Conclusion: MNEs can be a powerful engine for sustainable development if properly regulated and integrated into the local economy. The key is to design policies that maximise the benefits (technology transfer, job creation) while mitigating the drawbacks (profit repatriation, environmental damage).

Marking Notes:

• 1 mark for defining MNEs.
• 2–3 marks for benefits.
• 2–3 marks for drawbacks.
• 1 mark for a balanced conclusion.

Question 5 [6 marks]

Answer: A regional free trade agreement (FTA) eliminates tariffs and other trade barriers between member countries. Its effects on Country X can be analysed in terms of static and dynamic effects.

Static effects:

• Trade creation – The FTA allows Country X to import goods from more efficient producers within the region, replacing domestic production. This improves allocative efficiency and consumer welfare.
• Trade diversion – The FTA may cause Country X to switch imports from a more efficient producer outside the region to a less efficient producer within the region (because the latter enjoys tariff-free access). This reduces welfare.
• The net static effect depends on whether trade creation exceeds trade diversion.

Dynamic effects:

• Market expansion – Access to a larger regional market allows firms to achieve economies of scale.
• Increased competition – Regional competition incentivises domestic firms to innovate and improve efficiency.
• Investment attraction – The FTA may attract FDI from MNEs seeking to serve the regional market.
• Technology transfer – Greater integration facilitates the flow of technology and knowledge.
• Institutional reform – FTAs often require member countries to adopt certain standards and regulations, which can improve the business environment.

Evaluation:

• The net benefit depends on Country X's initial conditions. If its manufacturing sector is weak, it may face adjustment costs in the short run.
• The FTA's benefits are more likely to materialise if accompanied by complementary policies (education, infrastructure, structural reform).
• The risk of trade diversion can be mitigated by pursuing FTAs with countries that are already efficient producers.

Conclusion: An FTA can generate significant static and dynamic benefits for Country X, but the outcome depends on the specific terms of the agreement and the country's ability to adjust.

Marking Notes:

• 1 mark for defining an FTA.
• 2 marks for static effects (trade creation and diversion).
• 2 marks for dynamic effects.
• 1 mark for a reasoned conclusion.

Section B: Short Answer and Application (Questions 6–10)

Question 6 [3 marks]

Answer: Inclusive economic growth refers to growth that is broad-based across sectors of the economy and inclusive of a large portion of the country's labour force. It is growth that creates productive employment opportunities and reduces poverty and inequality.

It is considered a key component of sustainable development because:

• Sustainable development aims to meet the needs of the present without compromising the ability of future generations to meet their own needs.
• Growth that excludes large segments of the population can lead to social unrest, political instability, and erosion of social capital, undermining long-term development.
• Inclusive growth ensures that the benefits of growth are shared, contributing to human capital development and social cohesion, which are themselves inputs to future growth.

Marking Notes:

• 1 mark for a correct definition.
• 2 marks for explaining its link to sustainable development.

---

Question 7 [3 marks]

Answer: The tragedy of the commons is an economic concept where individuals, acting independently and rationally according to their own self-interest, deplete a shared, common-pool resource, even when it is not in anyone's long-term interest for this to happen. This occurs when there are no clearly defined property rights, leading to overuse and degradation of the resource.

Real-world example related to international environmental protection:

• Overfishing in international waters – Fish stocks in international waters are a common resource. No single country owns them, so each country has an incentive to fish as much as possible before others do. This leads to overfishing and the depletion of fish stocks, threatening the sustainability of the resource and the livelihoods of fishing communities.
• Climate change – The atmosphere is a common resource. Countries emit greenhouse gases without bearing the full cost of the damage, leading to excessive emissions and global warming.

Marking Notes:

• 1 mark for a correct definition.
• 2 marks for a relevant example with explanation.

---

Question 8 [4 marks]

Answer: The Solow growth model explains long-run economic growth as a function of capital accumulation, labour force growth, and technological progress. The model's production function can be written as:

$Y = A \cdot F(K, L)$

where $Y$ is output, $K$ is capital, $L$ is labour, and $A$ is the level of technology.

Key insights:

• In the Solow model, capital accumulation alone leads to diminishing returns. As the capital-to-labour ratio ($K/L$) increases, each additional unit of capital produces less additional output.
• Technological progress (increases in $A$) shifts the production function upward, allowing more output to be produced with the same inputs.
• In the long run, the economy reaches a steady state where capital per worker and output per worker are constant. Without technological progress, growth in output per worker stops.
• Technological progress is the only source of sustained growth in output per worker in the long run. It offsets the diminishing returns to capital and allows the economy to continue growing.

For a developing country:

• Technological progress can come from adopting existing technologies from developed countries (technology transfer), investing in research and development, and improving human capital.
• By improving technology, a developing country can increase its output per worker and converge towards the income levels of developed countries.

Marking Notes:

• 1 mark for stating the production function.
• 1 mark for explaining diminishing returns to capital.
• 1 mark for explaining that technology is the source of sustained growth.
• 1 mark for applying to a developing country.

Question 9 [4 marks]

Answer: Social capital refers to the networks of relationships among people who live and work in a particular society, enabling that society to function effectively. It includes trust, social norms, reciprocity, and civic engagement. In the Capital Approach framework, social capital is one of the five types of capital that contribute to a country's wealth and productive capacity.

Role of social capital:

• Facilitates cooperation – High social capital reduces transaction costs by enabling trust and cooperation between economic agents.
• Enables collective action – Social capital helps communities work together to provide public goods and manage common resources.
• Supports institutions – Social capital underpins the effective functioning of formal institutions (courts, government, markets).
• Enhances resilience – Communities with high social capital are better able to cope with shocks and recover from crises.

Effects of depletion:

• If social capital is depleted (e.g., through corruption, conflict, or erosion of trust), the cost of economic transactions increases.
• Investment and entrepreneurship may decline as property rights become less secure.
• Collective action problems (such as the tragedy of the commons) become harder to solve.
• The effectiveness of government policies is reduced.
• Overall, the country's productive capacity and sustainable development prospects are undermined.

Marking Notes:

• 1 mark for defining social capital.
• 1–2 marks for explaining its role.
• 1–2 marks for discussing the effects of depletion.

---

Question 10 [4 marks]

Answer: A negative externality occurs when the production or consumption of a good imposes costs on third parties who are not involved in the transaction. Climate change is a classic example: the emission of greenhouse gases from burning fossil fuels imposes costs (e.g., sea-level rise, extreme weather) on people worldwide who are not party to the energy transaction.

How a carbon tax improves efficiency:

• In a free market, the price of carbon-emitting goods does not reflect the full social cost of production. The market equilibrium quantity is too high, and the price is too low, leading to overproduction and overconsumption.
• A carbon tax is a Pigouvian tax that internalises the externality by adding a cost equal to the marginal external cost of carbon emissions.
• This shifts the supply curve upward (or the demand curve downward), reducing the quantity of carbon-intensive goods produced and consumed.
• The new market equilibrium moves closer to the socially optimal level, where marginal social cost equals marginal social benefit.
• The tax also creates a price signal that incentivises firms and households to reduce emissions, invest in cleaner technologies, and switch to low-carbon alternatives.

Marking Notes:

• 1 mark for defining negative externalities.
• 1 mark for explaining the market failure.
• 2 marks for explaining how the carbon tax corrects the failure.

Section C: Extended Response (Questions 11–20)

Question 11 [5 marks]

Answer: Free trade is the policy of allowing goods and services to be traded across borders without government-imposed tariffs, quotas, or other restrictions.

Arguments that free trade promotes economic development:

• Comparative advantage – Countries specialise in producing goods where they have a comparative advantage, leading to higher global output and efficiency.
• Economies of scale – Access to larger markets allows firms to produce at a larger scale, reducing average costs.
• Technology transfer – Trade facilitates the spread of technology and knowledge.
• Competition – Import competition incentivises domestic firms to innovate and improve efficiency.
• Consumer benefits – Consumers gain access to a wider variety of goods at lower prices.

Arguments against free trade as always best:

• Infant industry argument – Developing countries may need temporary protection to allow new industries to grow and achieve competitiveness.
• Terms of trade – Countries exporting primary commodities may face deteriorating terms of trade, limiting the gains from trade.
• Distributional effects – The gains from trade may be unevenly distributed, increasing inequality.
• Strategic trade policy – In industries with increasing returns and imperfect competition, government intervention can shift profits from foreign to domestic firms.
• Adjustment costs – Trade liberalisation can cause job losses and structural unemployment in the short run.

Conclusion: While free trade generally promotes economic efficiency and growth, it is not always the best policy for developing countries. A pragmatic approach that combines gradual liberalisation with complementary policies (education, infrastructure, institutional development) is often more effective.

Marking Notes:

• 1 mark for defining free trade.
• 2 marks for arguments in favour.
• 2 marks for counter-arguments.
• 1 mark for a reasoned conclusion.

Question 12 [5 marks]

Answer: Countries heavily dependent on natural resource exports face several economic challenges:

1. Dutch disease:

• Resource booms lead to an appreciation of the real exchange rate, making other traded sectors (manufacturing, agriculture) uncompetitive.
• This leads to deindustrialisation and over-reliance on the resource sector.

2. Price volatility:

• Commodity prices are highly volatile, leading to unstable government revenues and economic uncertainty.
• This makes planning and investment difficult.

3. Resource curse:

• Resource-rich countries often have weaker institutions, higher corruption, and more authoritarian governance.
• Resource wealth can fuel conflict over its control.

4. Unsustainable depletion:

• Natural capital is depleted without being reinvested in other forms of capital (produced, human, social).
• This undermines long-term sustainable development.

5. Crowding out of human capital:

• The resource sector is often capital-intensive, creating few jobs.
• There may be less incentive to invest in education and skills development.

6. Terms of trade:

• Primary commodity prices tend to fall relative to manufactured goods over time (Prebisch-Singer hypothesis), leading to deteriorating terms of trade.

Marking Notes:

• 1 mark for each well-explained challenge (max 5 marks).

Question 13 [5 marks]

Answer: The circular economy is an economic system aimed at eliminating waste and the continual use of resources. It is based on three principles: design out waste and pollution, keep products and materials in use, and regenerate natural systems. This contrasts with the traditional linear economy of "take-make-dispose."

Potential role in promoting sustainable development:

Environmental benefits:

• Reduces resource extraction and depletion of natural capital.
• Reduces pollution and waste, protecting ecosystems.
• Contributes to climate change mitigation by reducing emissions.

Economic benefits:

• Reduces costs for firms through resource efficiency.
• Creates new business opportunities in recycling, repair, and remanufacturing.
• Reduces dependence on imported raw materials, improving resource security.
• Stimulates innovation in product design and business models.

Social benefits:

• Creates jobs in recycling, repair, and remanufacturing sectors.
• Can reduce costs for consumers through longer-lasting products.

Challenges:

• Transition costs can be high.
• Requires significant changes in consumer behaviour and business models.
• May face resistance from vested interests in the linear economy.
• Requires supportive policies and infrastructure.

Conclusion: The circular economy offers a promising framework for decoupling economic growth from resource use and environmental degradation, contributing to sustainable development.

Marking Notes:

• 1 mark for defining the circular economy.
• 3 marks for benefits (environmental, economic, social).
• 1 mark for challenges or conclusion.

Question 14 [5 marks]

Answer: The Romer growth model is an endogenous growth model that emphasises the role of knowledge and ideas in driving economic growth. Unlike the Solow model, where technological progress is exogenous, the Romer model explains how technological progress arises from within the economy.

Key features:

• The economy has two sectors: a goods-producing sector and a research and development (R&D) sector.
• The R&D sector produces new ideas (knowledge) using human capital and the existing stock of knowledge.
• Knowledge spillovers occur because ideas are non-rivalrous – one person's use of an idea does not reduce its availability to others.

How knowledge spillovers lead to increasing returns:

• In the goods sector, output depends on capital, labour, and the stock of knowledge ($A$).
• The production of new knowledge depends on the existing stock of knowledge: $\dot{A} = \delta L_A A$, where $L_A$ is labour in R&D.
• Because knowledge is non-rivalrous, each new idea increases the productivity of all future research.
• This creates increasing returns to scale in the production of knowledge: the more knowledge we have, the easier it is to create new knowledge.
• Unlike physical capital, knowledge does not suffer from diminishing returns. Therefore, investment in R&D can generate sustained growth in output per worker.

Implications:

• Policies that promote R&D, education, and knowledge diffusion can generate long-run growth.
• Knowledge spillovers mean that the social return to R&D exceeds the private return, justifying government subsidies for research.

Marking Notes:

• 1 mark for identifying the Romer model as an endogenous growth model.
• 1 mark for explaining the role of R&D.
• 2 marks for explaining knowledge spillovers and increasing returns.
• 1 mark for policy implications.

Question 15 [5 marks]

Answer: Regional economic integration refers to agreements between countries to reduce or eliminate trade barriers and coordinate economic policies. Examples include free trade areas, customs unions, and common markets.

Potential benefits for a small open economy like Singapore:

Static benefits:

• Trade creation – Access to cheaper imports from member countries, improving consumer welfare.
• Larger market – Singapore's small domestic market is expanded, allowing firms to achieve economies of scale.

Dynamic benefits:

• Increased competition – Regional competition incentivises domestic firms to innovate and improve efficiency.
• Investment attraction – Singapore becomes a more attractive location for MNEs seeking to serve the regional market.
• Technology transfer – Greater integration facilitates the flow of technology and knowledge.
• Policy credibility – Regional commitments can lock in domestic reforms, improving the business environment.

Potential drawbacks:

• Trade diversion – Singapore may be forced to import from less efficient regional producers instead of more efficient producers outside the region.
• Loss of policy autonomy – Integration may require harmonising policies, limiting Singapore's ability to pursue independent economic policies.
• Competition pressure – Domestic firms may struggle to compete with regional rivals, leading to job losses.
• Asymmetric benefits – Larger member countries may capture a disproportionate share of the benefits.

Conclusion: For a small open economy like Singapore, regional integration generally offers net benefits, but the specific design of the agreement matters. Singapore should pursue integration with efficient partners and maintain flexibility in its domestic policies.

Marking Notes:

• 1 mark for defining regional economic integration.
• 2 marks for benefits.
• 2 marks for drawbacks.
• 1 mark for a reasoned conclusion.

Question 16 [5 marks]

Answer: Tradeable permits (also known as cap-and-trade systems) are a market-based policy tool for addressing climate change. The government sets a cap on total emissions and issues permits equal to that cap. Firms must hold permits for their emissions and can trade permits among themselves.

Effectiveness:

Strengths:

• Cost-effectiveness – Firms that can reduce emissions cheaply will do so and sell their excess permits, while firms with high abatement costs will buy permits. This ensures that emissions are reduced at the lowest possible cost.
• Environmental certainty – The cap sets a firm limit on total emissions, ensuring that the environmental target is met.
• Incentives for innovation – The price signal created by the permit market incentivises firms to invest in cleaner technologies.
• Flexibility – Firms have flexibility in how they meet their emissions targets.

Weaknesses:

• Setting the cap – The cap must be set at the socially optimal level, which is difficult to determine.
• Initial allocation – The initial distribution of permits can be politically contentious. Free allocation may create windfall profits for polluters, while auctioning raises revenue but may face political opposition.
• Market power – Large firms may be able to manipulate the permit market.
• Enforcement – Effective monitoring and enforcement are required to prevent cheating.
• Carbon leakage – Firms may relocate production to countries without carbon pricing, undermining the effectiveness of the policy.
• Price volatility – Permit prices can be volatile, creating uncertainty for firms.

Conclusion: Tradeable permits are an effective and efficient tool for reducing emissions when properly designed and enforced. However, they are not a panacea and may need to be complemented by other policies (e.g., carbon taxes, regulations, subsidies for clean energy).

Marking Notes:

• 1 mark for defining tradeable permits.
• 2 marks for strengths.
• 2 marks for weaknesses.
• 1 mark for a reasoned conclusion.

Question 17 [5 marks]

Answer: Globalisation refers to the increasing integration of economies through trade, investment, and the flow of information and technology.

Relationship between globalisation and income inequality:

Within countries:

• Globalisation can increase inequality within countries by:
  • Increasing demand for skilled labour (which is complementary to technology and trade) while reducing demand for unskilled labour in developed countries.
  • Allowing firms to outsource production to low-wage countries, putting downward pressure on wages for unskilled workers in developed countries.
  • Increasing the returns to capital relative to labour.
• However, globalisation can also reduce inequality by:
  • Creating new job opportunities in export sectors.
  • Lowering consumer prices, which benefits lower-income households disproportionately.

Between countries:

• Globalisation has contributed to a reduction in inequality between countries, particularly due to the rapid growth of China and India.
• However, some developing countries (especially in Africa) have been left behind, leading to a divergence in incomes.

Evaluation:

• The relationship between globalisation and inequality is complex and context-dependent.
• The impact depends on a country's initial conditions, its policies, and its position in the global economy.
• Globalisation is not the only driver of inequality; technological change and domestic policies also play important roles.

Conclusion: Globalisation has both increased and decreased inequality, depending on the context. Policies to manage the distributional effects of globalisation (e.g., education, social safety nets, progressive taxation) are essential to ensure that its benefits are widely shared.

Marking Notes:

• 1 mark for defining globalisation.
• 2 marks for within-country effects.
• 1 mark for between-country effects.
• 1 mark for a reasoned conclusion.

Question 18 [5 marks]

Answer: Foreign direct investment (FDI) is an investment made by a firm or individual in one country into business interests located in another country, typically involving establishing operations or acquiring assets.

Role of FDI in promoting sustainable development:

Positive contributions:

• Capital formation – FDI supplements domestic savings, providing funds for investment in infrastructure and productive capacity.
• Technology transfer – MNEs bring advanced technology and managerial practices, which can spill over to domestic firms.
• Human capital development – MNEs provide training and skill development for local workers.
• Job creation – FDI creates direct employment and indirect jobs through supply chains.
• Export promotion – FDI can help developing countries diversify their exports and integrate into global value chains.
• Tax revenue – FDI contributes to government revenue through corporate taxes.
• Environmental standards – Some MNEs bring higher environmental standards to host countries.

Negative contributions:

• Profit repatriation – MNEs may repatriate profits, reducing the net capital inflow.
• Crowding out – MNEs may outcompete domestic firms, leading to market concentration.
• Environmental degradation – MNEs may exploit weak environmental regulations.
• Transfer pricing – MNEs may shift profits to low-tax jurisdictions, reducing tax revenue.
• Dependency – Over-reliance on FDI can make the economy vulnerable to MNEs' decisions.

Conclusion: FDI can be a powerful engine for sustainable development, but its impact depends on the host country's policies and the nature of the investment. Policies should aim to maximise the benefits (technology transfer, job creation) while mitigating the risks (profit repatriation, environmental damage).

Marking Notes:

• 1 mark for defining FDI.
• 2–3 marks for positive contributions.
• 1–2 marks for negative contributions.
• 1 mark for a reasoned conclusion.

Question 19 [5 marks]

Answer: Dynamic comparative advantage refers to the idea that a country's comparative advantage can change over time due to factors such as technological progress, human capital development, and investment in infrastructure. Unlike static comparative advantage (based on current factor endowments), dynamic comparative advantage recognises that countries can develop new areas of competitive strength.

How governments can use industrial policy to promote dynamic comparative advantage:

1. Investment in education and training – Improving human capital can help a country develop comparative advantage in skill-intensive industries.
2. Investment in infrastructure – Good infrastructure (transport, communications, energy) reduces production costs and attracts investment.
3. R&D subsidies – Government support for research and development can help develop new technologies and industries.
4. Targeted support for strategic industries – Governments may provide subsidies, tax breaks, or protection to help infant industries grow and achieve competitiveness.
5. Trade policy – Temporary protection from imports can give domestic industries time to develop.
6. Attracting FDI – Policies to attract FDI can bring technology and knowledge that help develop new industries.
7. Institutional reform – Improving property rights, reducing corruption, and strengthening the rule of law can create a better environment for investment and innovation.

Evaluation:

• Industrial policy can be effective in promoting dynamic comparative advantage, as evidenced by the success of East Asian economies (e.g., South Korea, Taiwan).
• However, it can also fail if governments pick losers or are captured by special interests.
• The key is to design policies that are targeted, time-bound, and subject to competition.

Marking Notes:

• 1 mark for defining dynamic comparative advantage.
• 3 marks for policy measures.
• 1 mark for evaluation.

Question 20 [5 marks]

Answer: The view that economic growth is incompatible with environmental protection is a central debate in environmental economics.

Arguments that they are incompatible:

• Scale effect – Economic growth increases the scale of production and consumption, leading to more resource extraction and pollution.
• Energy dependence – Growth requires energy, and most energy currently comes from fossil fuels, which cause climate change.
• Planetary boundaries – The Earth has finite resources and limited capacity to absorb waste. Unlimited growth will eventually exceed these limits.
• Jevons paradox – Efficiency improvements may lead to more consumption, not less (rebound effect).

Arguments that they can be compatible:

• Technological progress – Innovation can decouple growth from resource use and emissions. Renewable energy, circular economy, and energy efficiency can reduce environmental impact per unit of GDP.
• Structural change – As economies develop, they shift from manufacturing to services, which are less resource-intensive.
• Environmental Kuznets curve – Some evidence suggests that pollution first increases and then decreases with income, as societies demand cleaner environments and can afford to invest in them.
• Green growth – Policies can steer growth towards environmentally sustainable activities.
• Substitution – Natural capital can be substituted with produced and human capital (weak sustainability).

Evaluation:

• The compatibility of growth and environmental protection depends on the type of growth and the policies in place.
• "Brown" growth (based on resource extraction and pollution) is likely incompatible with environmental protection.
• "Green" growth (based on innovation and efficiency) may be compatible, but it requires strong policy intervention.
• There is a risk that the concept of "green growth" is used to justify continued unsustainable consumption.

Conclusion: While traditional economic growth has often been environmentally damaging, it is not necessarily incompatible with environmental protection. The key is to shift towards a model of sustainable development that prioritises human well-being and environmental quality over mere GDP growth.

Marking Notes:

• 1 mark for presenting the incompatibility argument.
• 2 marks for presenting the compatibility argument.
• 1 mark for evaluation.
• 1 mark for a reasoned conclusion.
