Answer Key - A-Level Economics H2 Quiz (Macroeconomics)

1. Real GDP vs Nominal GDP (4 marks)

• Definition: Real GDP is the total value of all final goods and services produced within a country in a year, adjusted for inflation. (2m)
• Explanation: Nominal GDP uses current prices, which can rise due to inflation even if output is stagnant. Real GDP uses constant prices, reflecting actual changes in physical output/volume. (2m)

2. Cyclical vs Structural Unemployment (4 marks)

• Cyclical: Caused by a deficiency in aggregate demand during a recession (e.g., construction workers during a housing market crash). (2m)
• Structural: Caused by a mismatch between the skills of workers and the requirements of available jobs due to technological change or industry decline (e.g., assembly line workers replaced by robotics). (2m)

3. Oil Price Shock AD-AS (6 marks)

• Diagram: SRAS shifts leftward. (2m)
• Analysis: Higher oil prices increase production costs for firms $\rightarrow$ SRAS shifts left $\rightarrow$ Price level increases (cost-push inflation) and Real GDP decreases. (4m)

4. Demand-Pull vs Cost-Push Inflation (4 marks)

• Demand-Pull: Occurs when AD increases faster than AS (too much spending chasing too few goods). (2m)
• Cost-Push: Occurs when the cost of production increases, shifting SRAS to the left. (2m)

5. Multiplier Calculation (6 marks)

• Calculation: $Multiplier = 1 / MPS = 1 / 0.15 \approx 6.67$. (2m)
• Explanation: Initial injection of $2bn $\rightarrow$ Total increase in income = 2 \times 6.67 = \13.34$ billion. (2m)
• Mechanism: Initial spending becomes income for others, who spend a portion (MPV), triggering subsequent rounds of spending. (2m)

6. Circular Flow (4 marks)

• Concept: A model showing the flow of money, goods, and services between sectors (Households, Firms, Government, Foreign sector). (2m)
• Leakages: Savings, Taxes, Imports. (1m)
• Injections: Investment, Government Spending, Exports. (1m)

7. Stagflation (8 marks)

• Explanation: Simultaneous occurrence of stagnant growth (high unemployment) and high inflation. (2m)
• Diagram: Leftward shift of SRAS. (2m)
• Challenge: Policy conflict. Expansionary policy to fix unemployment increases inflation; contractionary policy to fix inflation worsens unemployment. (4m)

8. Monetary Policy Transmission (6 marks)

• Mechanism: Central bank increases money supply/lowers interest rates $\rightarrow$ borrowing costs for firms and households decrease $\rightarrow$ Investment (I) and Consumption (C) increase $\rightarrow$ AD shifts right $\rightarrow$ Real GDP increases. (6m)

9. Discretionary vs Automatic Stabilisers (8 marks)

• Automatic: Built-in mechanisms (e.g., progressive taxes, unemployment benefits) that cushion shocks without new legislation. Fast acting but may be insufficient for deep recessions. (4m)
• Discretionary: Deliberate government action (e.g., new infrastructure project, tax cuts). More targeted and powerful but suffers from time lags (recognition, implementation). (4m)

10. Supply-Side Policies (8 marks)

• Definition: Policies aimed at increasing the productive capacity (LRAS) of the economy. (2m)
• Examples: Education/training (human capital), deregulation, infrastructure investment. (2m)
• Analysis: Shifts LRAS to the right $\rightarrow$ increases potential output (growth) while keeping prices stable (lowering unit costs). (4m)

11. Crowding-Out Effect (6 marks)

• Explanation: Increased government borrowing to fund fiscal expansion $\rightarrow$ increases demand for loanable funds $\rightarrow$ pushes up interest rates $\rightarrow$ reduces private investment. (6m)

12. Money Supply & Investment (6 marks)

• Diagram: Money market diagram showing MS shifting right $\rightarrow$ equilibrium interest rate falls. (3m)
• Analysis: Lower interest rates reduce the cost of capital $\rightarrow$ firms find more projects profitable $\rightarrow$ Investment increases. (3m)

13. Phillips Curve Trade-off (10 marks)

• Analysis: Inverse relationship between inflation and unemployment in the short run. (3m)
• Mechanism: Low unemployment $\rightarrow$ tight labor market $\rightarrow$ higher nominal wages $\rightarrow$ higher costs for firms $\rightarrow$ higher prices (inflation). (4m)
• Evaluation: In the long run, the Phillips Curve is vertical (NRU); expectations adjust, and the trade-off disappears. (3m)

14. Supply-Side for Structural Unemployment (6 marks)

• Reason: Demand-management (fiscal/monetary) increases AD but does not fix the "skills gap." (3m)
• Solution: Supply-side policies (retraining, vocational education) address the root cause by aligning worker skills with industry needs. (3m)

15. Comparative Advantage (6 marks)

• Definition: The ability of a country to produce a good at a lower opportunity cost than another country. (3m)
• Basis for Trade: Countries specialize in goods where they have the lowest opportunity cost and trade for others, increasing total global output and consumption. (3m)

16. Currency Appreciation (6 marks)

• Mechanism: Appreciation $\rightarrow$ domestic goods become more expensive for foreigners (exports $\downarrow$) and foreign goods become cheaper for domestic consumers (imports $\uparrow$). (3m)
• Result: Decrease in price competitiveness of exports in global markets. (3m)

17. Marshall-Lerner Condition (8 marks)

• Condition: A depreciation improves the current account only if the sum of the price elasticities of demand for exports and imports is greater than 1 ($PED_x + PED_m > 1$). (4m)
• Analysis: If demand is inelastic, the price drop doesn't lead to a sufficient increase in export volume or decrease in import volume to offset the price change. (4m)

18. Protectionism (8 marks)

• Benefits: Protects infant industries, preserves domestic jobs, improves national security. (4m)
• Drawbacks: Higher prices for consumers, loss of efficiency (lack of competition), risk of retaliation from trading partners. (4m)

19. Fixed vs Managed Float (6 marks)

• Fixed: Currency value is pegged to another currency or gold; requires significant reserves to maintain. (3m)
• Managed Float: Market forces determine the rate, but the central bank intervenes occasionally to prevent excessive volatility. (3m)

20. Singapore Exchange Rate Policy (10 marks)

• Context: Singapore uses the exchange rate (NEER) as its primary monetary tool because it is a small, open economy and a price-taker. (3m)
• Analysis: Managing the SGD prevents imported inflation and maintains export competitiveness. (4m)
• Evaluation: Effective for price stability but limits the ability to use interest rates independently; highly dependent on global trade volumes. (3m)
