Answers

A-Level Economics H2 Quiz - Policy Evaluation (Answer Key)

Section A: Microeconomic Policy Evaluation

1. Define the term 'government failure'. [2]

Answer: Government failure occurs when government intervention in the economy leads to a net welfare loss or a misallocation of resources, resulting in an outcome that is less efficient than the free market outcome.
Marks: 1 mark for defining intervention/misallocation; 1 mark for noting it creates inefficiency/welfare loss compared to the market.

2. Explain one reason why a subsidy on merit goods (e.g., education) might lead to a more efficient allocation of resources. [3]

Answer: Merit goods are under-consumed in a free market because individuals underestimate the private benefits (information failure) or cannot afford them. A subsidy lowers the cost of production/consumption, shifting the supply curve right (or demand right). This lowers the price and increases quantity consumed towards the socially optimal level, reducing the deadweight welfare loss.
Marks: 1 for identifying under-consumption/information failure; 1 for mechanism (subsidy lowers price/increases Q); 1 for linking to social optimum/efficiency.

Answer: Cigarettes have price inelastic demand (PED < 1) due to addiction and lack of substitutes, meaning a tax-induced price rise leads to a proportionately smaller fall in quantity demanded. However, the question asks about effectiveness in reducing consumption. Actually, luxury yachts have price elastic demand (PED > 1). A tax on yachts will cause a large fall in quantity demanded. Therefore, the tax on yachts is more effective at reducing consumption volume, while the tax on cigarettes is more effective at raising revenue. Correction/Refinement: If the goal is strictly reducing consumption volume, elastic goods respond more. If the goal is reducing smoking specifically despite inelasticity, the tax must be very high.
Key Distinction: The prompt implies a comparison. Cigarettes (inelastic) -> Small drop in Q. Yachts (elastic) -> Large drop in Q. Thus, tax on yachts reduces consumption more in percentage terms.
Marks: 1 for defining PED for cigarettes (inelastic); 1 for defining PED for yachts (elastic); 1 for explaining impact on Q for cigarettes (small change); 1 for explaining impact on Q for yachts (large change) and concluding which is more effective for volume reduction.

4. "Price ceilings (maximum prices) always benefit consumers." Evaluate this statement. [6]

Answer:
- Analysis (Pro): Price ceilings set below equilibrium make goods more affordable for those who can buy them, increasing consumer surplus for successful buyers and helping low-income groups (equity).
- Analysis (Con): They create excess demand (shortages). This leads to non-price rationing (queues, black markets), reduced quality, and some consumers being unable to buy the good at all. Long-term supply may decrease as producers exit.
- Evaluation: It depends on the elasticity of supply and demand, the duration of the policy, and whether complementary policies (rationing) are in place. It does not always benefit consumers; many may be worse off due to unavailability.
Marks: 2 for benefits (affordability/equity); 2 for drawbacks (shortages/black markets); 2 for evaluation (depends on context/elasticity/not always beneficial).

5. Analyse how the imposition of a carbon tax on firms producing negative externalities of production affects market equilibrium and social welfare. Include a diagram in your answer. [8]

Answer:
- Diagram: MSC > MPC. Tax shifts MPC left/up to MPC+tax. New equilibrium at higher Price (P1 to P2) and lower Quantity (Q1 to Q2). Q2 should ideally align with socially optimal quantity (where MSC=MSB).
- Analysis: The tax internalizes the externality. Firms face higher costs, reducing supply. Price rises, contracting demand. The reduction in output reduces the negative externality (pollution). Deadweight welfare loss is reduced/eliminated if the tax equals the marginal external cost.
- Marks: 3 for correct diagram (MSC, MPC, MSB, Tax shift, Optimal Q); 3 for explanation of internalization and movement to social optimum; 2 for linking to welfare loss reduction.

6. Evaluate the effectiveness of tradable pollution permits compared to carbon taxes in reducing industrial pollution. [10]

Answer:
- Tradable Permits: Sets a fixed quantity of pollution (certainty in environmental outcome). Market determines price. Encourages firms with low abatement costs to sell permits. Effective if the cap is set correctly.
- Carbon Taxes: Sets a fixed price on pollution (certainty in cost). Quantity of reduction depends on elasticity of demand for pollution. Generates government revenue.
- Comparison: Permits are better if the ecological threshold is critical (quantity certainty). Taxes are better if economic stability/cost certainty is preferred. Permits can be volatile in price; taxes can be adjusted.
- Evaluation: Both rely on accurate data. Permits may suffer from initial allocation issues (grandfathering vs auctioning). Taxes face political resistance. In practice, a hybrid or context-specific approach is best.
Marks: 3 for analysis of permits; 3 for analysis of taxes; 2 for comparison; 2 for evaluated judgment on effectiveness.

7. Explain two limitations of using legislation/regulation to correct market failure caused by information asymmetry. [4]

Answer:
1. Enforcement Costs: Monitoring compliance (e.g., checking food labels, financial disclosures) is expensive for the government.
2. Information Gap: Regulators may not have better information than the market participants, leading to ineffective rules. Or, firms may find loopholes.
Marks: 2 marks per limitation (1 for identifying, 1 for explaining).

8. "Privatisation of state-owned enterprises always leads to greater economic efficiency." Discuss. [6]

Answer:
- Analysis (Pro): Privatisation introduces profit motive, competition, and hard budget constraints. This encourages cost-cutting, innovation, and allocative efficiency (if competition exists).
- Analysis (Con): If privatisation creates a private monopoly, the firm may raise prices and restrict output to maximize profit, reducing allocative efficiency. Natural monopolies (e.g., water rails) may not benefit from competition.
- Evaluation: It depends on the market structure post-privatisation. Regulation is often needed. "Always" is incorrect; it depends on the industry and regulatory framework.
Marks: 2 for efficiency gains (productive/dynamic); 2 for potential losses (monopoly power); 2 for evaluation (context/regulation needed).

9. Analyse the impact of a minimum wage policy on the labour market for low-skilled workers. Use a diagram to illustrate your answer. [8]

Answer:
- Diagram: Labour Demand (D) and Supply (S). Minimum wage (Wmin) set above equilibrium (We). Result: Excess supply of labour (Unemployment) = Qs - Qd.
- Analysis: Workers who keep jobs earn higher wages (income effect). However, firms may hire fewer workers due to higher costs (substitution effect/capital for labour). Unemployment rises among low-skilled workers. May lead to informal sector growth.
- Marks: 3 for diagram (Wmin > We, Unemployment gap); 3 for analysis of winners (employed) and losers (unemployed/firms); 2 for broader implications (informal sector/cost-push inflation).

10. Evaluate whether government provision of public goods is the only way to ensure their supply. [9]

Answer:
- Analysis: Public goods (non-rival, non-excludable) suffer from free-rider problem. Private markets will not supply them (missing market). Government provision funded by taxes is the standard solution.
- Alternative: Private provision is possible if excludability is engineered (e.g., toll roads, encrypted TV signals - technically club goods). Charities/NGOs may provide some public-like goods (street lighting via business improvement districts).
- Evaluation: For pure public goods (national defence), government is the only viable provider. For quasi-public goods, private/charitable sectors can contribute. Government provision ensures universal access but may suffer from government failure (inefficiency).
Marks: 3 for explaining market failure/free-rider; 3 for alternatives (club goods/charities); 3 for evaluation (pure vs quasi, efficiency trade-offs).

Section B: Macroeconomic Policy Evaluation

11. Define 'automatic stabilisers' in the context of fiscal policy. [2]

Answer: Automatic stabilisers are mechanisms built into the government budget (such as progressive income tax and unemployment benefits) that automatically dampen fluctuations in the business cycle without explicit policy changes. They increase deficits during recessions and surpluses during booms.
Marks: 1 for identifying mechanisms (tax/benefits); 1 for explaining counter-cyclical effect.

12. Explain how an increase in government spending can lead to a multiplied increase in national income. [3]

Answer: Initial government spending becomes income for recipients (workers/firms). They spend a portion of this income (determined by MPC), which becomes income for others. This cycle continues. The total increase in national income is greater than the initial injection, determined by the multiplier formula $1/(1-MPC)$ .
Marks: 1 for initial injection becoming income; 1 for induced consumption/MPC; 1 for cumulative effect/multiplier concept.

13. With reference to the Phillips Curve, explain the short-run trade-off between inflation and unemployment. [4]

Answer: The Short-Run Phillips Curve (SRPC) is downward sloping. It suggests that as aggregate demand increases, unemployment falls (movement along SRPC) but inflation rises due to demand-pull pressures and rising wages. Conversely, reducing inflation may require higher unemployment. This trade-off exists because of nominal wage rigidity and misperceptions in the short run.
Marks: 1 for downward sloping SRPC; 1 for inverse relationship; 1 for cause (AD increase/wage pressures); 1 for short-run context.

14. "Expansionary monetary policy is always effective in stimulating economic growth during a recession." Evaluate this statement. [6]

Answer:
- Analysis (Pro): Lower interest rates reduce cost of borrowing, encouraging investment and consumption. Asset prices rise (wealth effect). Exchange rate may depreciate, boosting net exports.
- Analysis (Con): In a deep recession, confidence may be low (liquidity trap). Firms may not invest despite low rates if demand is weak. Banks may not lend (credit crunch). Time lags exist.
- Evaluation: Not "always" effective. Depends on interest rate elasticity of demand, consumer/business confidence, and banking sector health. Fiscal policy may be more effective in severe recessions.
Marks: 2 for transmission mechanism; 2 for limitations (liquidity trap/confidence); 2 for evaluation (context/elasticity).

15. Analyse the potential conflicts between the macroeconomic objectives of price stability and full employment. [8]

Answer:
- Analysis: Pursuing full employment often involves expansionary policies (fiscal/monetary) to boost AD. This can lead to demand-pull inflation as the economy nears full capacity (wage-price spiral).
- Diagram: AD/AS showing AD shift right leading to higher Price Level and higher Real GDP (lower unemployment).
- Conflict: Low unemployment tightens the labour market, raising wages and costs (cost-push inflation). Conversely, fighting inflation via contractionary policy raises unemployment.
- Marks: 3 for explanation of expansionary policy impact; 3 for wage-price spiral/cost-push link; 2 for diagram/summary of conflict.

16. Evaluate the effectiveness of supply-side policies in achieving long-term economic growth compared to demand-side policies. [10]

Answer:
- Supply-Side: Aim to shift LRAS right (education, infrastructure, deregulation). Increases productive potential, non-inflationary growth. Takes time to work (time lags). Expensive upfront.
- Demand-Side: Aim to shift AD right. Quick impact on growth. Risk of inflation if economy is near full capacity. Does not increase long-term potential.
- Comparison: Supply-side is superior for long-term sustainable growth and price stability. Demand-side is better for short-term stabilization.
- Evaluation: Best approach is a mix. Supply-side reforms need demand support to be effective. Effectiveness depends on the specific policy design and economic context.
Marks: 3 for supply-side analysis; 3 for demand-side analysis; 2 for comparison; 2 for evaluated judgment.

17. Explain two reasons why a country might choose to maintain a fixed exchange rate regime despite the loss of monetary policy independence. [4]

Answer:
1. Certainty for Trade: Reduces exchange rate risk for exporters/importers, encouraging international trade and investment.
2. Discipline on Inflation: Anchors inflation expectations by tying the currency to a low-inflation currency (importing credibility). Prevents competitive devaluation.
Marks: 2 marks per reason (1 for identifying, 1 for explaining).

18. "Protectionist policies (e.g., tariffs) are justified to protect infant industries." Discuss the validity of this argument. [6]

Answer:
- Argument For: Infant industries lack economies of scale and experience. Temporary protection allows them to grow, achieve efficiency, and compete globally later (dynamic efficiency).
- Argument Against: Protection reduces incentive to become efficient (complacency). Consumers pay higher prices. Retaliation from other countries. Hard to remove protection once granted (political economy).
- Evaluation: Valid only if the industry has genuine potential for comparative advantage and protection is temporary. Often fails in practice due to lobbying.
Marks: 2 for infant industry argument; 2 for counter-arguments (inefficiency/costs); 2 for evaluation (conditions for validity).

19. Analyse the impact of a depreciation in the exchange rate on a country’s balance of payments on the current account. Refer to the Marshall-Lerner condition in your answer. [8]

Answer:
- Analysis: Depreciation makes exports cheaper (foreign currency) and imports expensive (domestic currency). Volume of exports should rise, volume of imports fall.
- Marshall-Lerner Condition: The sum of price elasticities of demand for exports and imports must be greater than 1 ( $PED_x + PED_m > 1$ ) for the value of the current account to improve.
- J-Curve: In the short run, elasticities are low (contracts in place), so the current account may worsen before improving.
- Marks: 3 for price/volume effects; 3 for Marshall-Lerner explanation; 2 for J-curve/short-run vs long-run distinction.

20. Evaluate the suitability of fiscal policy versus monetary policy for controlling demand-pull inflation in a small open economy like Singapore. [9]

Answer:
- Monetary Policy: Singapore uses exchange rate policy (MAS) rather than interest rates. Appreciating the SGD helps reduce import prices (imported inflation) and dampens AD. Highly suitable for small open economy heavily reliant on trade.
- Fiscal Policy: Contractionary fiscal policy (tax hikes/spending cuts) reduces AD directly. However, it is politically difficult, slow to implement, and may harm long-term growth potential.
- Evaluation: For Singapore, exchange rate policy is the primary tool for price stability because it directly addresses imported inflation. Fiscal policy plays a supporting role. Monetary (interest rate) policy is less effective due to capital mobility and small domestic market.
Marks: 3 for Singapore's unique monetary policy (exchange rate); 3 for fiscal policy limitations; 3 for evaluated judgment on suitability for SOE.
