2023 Cambridge IGCSE Economics (0455) Practice Paper with Answers

To increase steel production from 20 tonnes (combination X) to 35 tonnes (combination Y), the country must reduce its wheat production from 80 tonnes to 50 tonnes. The opportunity cost is the foregone alternative, which is the 30 tonnes of wheat given up (\(80 - 50 = 30\)).

1 mark for the correct option B.

When demand is price-elastic, a fall in price leads to a proportionately larger increase in quantity demanded, which increases total revenue. Since the 10% price reduction caused total revenue to rise, the demand must be price-elastic.

1 mark for the correct option B.

Marginal cost is the change in total cost resulting from producing one additional unit of output.

\(\text{Marginal Cost of 12th unit} = \text{Total Cost of 12 units} - \text{Total Cost of 11 units}\)
\(\text{Marginal Cost} = \$144 - \$130 = \$14\).

1 mark for the correct option C.

Structural unemployment occurs when there is a mismatch between the skills of the unemployed workers and the skills needed for the available jobs, often caused by industrial reorganization or offshoring.

1 mark for the correct option D.

A tariff is a tax on imported goods. By increasing the cost of importing foreign cars, their market price rises, which decreases consumer demand for them. This leads to a lower volume of car imports.

1 mark for the correct option C.

A credit entry (+) represents an inflow of money into the country. When a foreign tourist spends money on services provided by a local hotel, it is treated as an export of services, resulting in an inflow of currency (credit).

1 mark for the correct option A.

Expansionary monetary policy aims to stimulate economic activity by increasing the money supply or reducing the cost of borrowing. Lowering the base interest rate makes borrowing cheaper for households and firms, which encourages spending and investment.

1 mark for the correct option C.

A monopoly is characterized by a single supplier dominating the market, which is protected by high barriers to entry and exit, preventing new competitors from entering.

1 mark for the correct option C.

Price elasticity of demand (PED) is calculated as:

$$\text{PED} = \frac{\% \text{ change in quantity demanded}}{\% \text{ change in price}} = \frac{-5\%}{10\%} = -0.5$$

Since the absolute value of PED is less than 1 (demand is inelastic), the percentage increase in price is greater than the percentage decrease in quantity demanded. Therefore, total revenue will increase.

1 mark for the correct option A.

1. At zero units of output, the total cost is $100. This is the firm's total fixed cost (TFC = $100).
2. At 4 units of output, the total cost (TC) is $300.
3. The total variable cost (TVC) at 4 units of output is calculated as:
$$\text{TVC} = \text{TC} - \text{TFC} = \$300 - \$100 = \$200$$
4. The average variable cost (AVC) is calculated as:
$$\text{AVC} = \frac{\text{TVC}}{\text{Output}} = \frac{\$200}{4} = \$50$$

1 mark for the correct option B.

When a currency appreciates, it becomes stronger. Consequently:
- Foreign buyers need more of their own currency to purchase the same amount of Country Y's currency, making exports from Country Y more expensive (export prices rise).
- Domestic buyers need less of their own currency to buy foreign goods, making imported items cheaper (import prices fall).

1 mark for the correct option B.

Supply-side policies aim to increase the productive capacity of the economy. Subsidised vocational training schemes improve the skills and productivity of the workforce, directly targeting structural unemployment by aligning worker skills with vacant jobs. Options A and D are expansionary demand-side policies (fiscal and monetary, respectively). Option B is a labor market regulation.

1 mark for the correct option C.

When a foreign tourist spends money on local services (like hotels and restaurants) in Country B, Country B is selling services to a foreign resident. This results in an inflow of money to Country B, which is recorded as a trade in services export.

1 mark for the correct option C.

A point inside the PPC indicates that resources are unemployed or being used inefficiently. Moving to a point on the PPC means the economy is now utilizing its available resources fully and efficiently, thereby reducing the level of resource unemployment. Outward shifts or capacity increases represent economic growth, which would be represented by the PPC shifting, not a movement from inside to on the curve.

1 mark for the correct option B.

A decrease in the rate of inflation (disinflation) means that prices are still rising, but at a slower rate. Because the rate of inflation is still positive (2%), the general price level rose. Since prices rose, the purchasing power of money fell (though more slowly than in Year 1).

1 mark for the correct option A.

A monopoly is defined by a single seller that dominates the entire market. There are high barriers to entry/exit, and the product sold has no close substitutes. Options A and C describe characteristics closer to perfect competition or monopolistic competition.

1 mark for the correct option B.

A subsidy on fertilizers reduces production costs and shifts the supply curve of chemical fertilizers to the right, which acts to reduce price and increase quantity. The shift in consumer preference away from chemical-grown crops reduces the demand for chemical fertilizers, shifting the demand curve to the left, which acts to reduce price and decrease quantity. Therefore, the price of chemical fertilizers will definitely fall, but the net effect on the quantity traded depends on which shift is larger and is thus uncertain.

Award 1 mark for the correct option C. Option A is incorrect because price will fall, not rise. Option B is incorrect because the effect on quantity is uncertain. Option D is incorrect because the price will definitely fall.

At 0 loaves of output, the total cost is $50, which represents the firm's fixed cost. When output is 20 loaves, the total cost is $100. Thus, Total Variable Cost (TVC) = Total Cost - Fixed Cost = $100 - $50 = $50. The Average Variable Cost (AVC) is TVC divided by output: $50 / 20 = $2.50.

Award 1 mark for calculating Fixed Cost ($50), Total Variable Cost ($50), and then dividing by the quantity of 20 to get the correct answer of $2.50 (Option A).

A tariff on steel raises the price of imported steel. This increases raw material costs for domestic manufacturers that use steel to make other products (such as cars or machinery). Higher costs will decrease their profit margins. Domestic steel producers will increase output (not decrease) due to protection, and steel imports will decrease (not increase).

Award 1 mark for the correct option C. Option A is incorrect because domestic steel production increases. Option B is incorrect because domestic steel prices will rise. Option D is incorrect because imports of steel will fall.

The current account balance is computed as: Trade in Goods Balance (Exports of goods - Imports of goods = 120 - 140 = -20) + Trade in Services Balance (Exports of services - Imports of services = 60 - 45 = +15) + Primary Income Balance (-10) + Secondary Income Balance (+5). Therefore, Current Account Balance = -20 + 15 - 10 + 5 = -10 billion (a deficit of $10 billion).

Award 1 mark for the correct calculation showing a deficit of $10 billion (Option A).

Increasing direct taxes reduces consumers' disposable incomes, which lowers consumer spending. Decreasing government spending directly reduces aggregate demand. These contractionary fiscal policies reduce economic growth, and as a consequence of lower production, firms lay off workers, causing unemployment to rise.

Award 1 mark for recognizing that contractionary fiscal policy reduces economic growth and raises unemployment in the short run (Option B).

Percentage change in Price = \(((12 - 10) / 10) \times 100\) = 20%. Percentage change in Quantity Supplied = \(((550 - 500) / 500) \times 100\) = 10%. Price Elasticity of Supply (PES) = % change in Qs / % change in Price = 10% / 20% = 0.5.

Award 1 mark for using percentage changes correctly to calculate PES = 0.5 (Option A).

A market dominated by a single seller is a monopoly. Monopolies are price-makers because they control the total market supply, giving them price-making power. Barriers to entry are high (ruling out A), there is no price competition (ruling out B), and information is highly imperfect (ruling out C).

Award 1 mark for identifying price-making power as a standard monopoly feature (Option D).

Higher interest rates attract foreign investment looking for higher returns ('hot money'). To save in country Z, foreign financial investors must convert their funds, increasing the demand for country Z's currency. Higher demand causes the currency's exchange rate to appreciate.

Award 1 mark for identifying both the increase in currency demand and the appreciation of the exchange rate (Option D).

Opportunity cost is the value of the next best alternative forgone. The alternatives to wheat are barley ($450) and potatoes ($550). The next best alternative is potatoes, valued at $550.

1 mark for the correct option B.

When the price rises and total revenue falls, the percentage fall in quantity demanded must be greater than the percentage rise in price. This means the price elasticity of demand is greater than 1, indicating that demand is price-elastic.

1 mark for the correct option D.

Total Cost (TC) = Total Fixed Cost (TFC) + Total Variable Cost (TVC). Since Average Fixed Cost (AFC) is $1 per unit and 100 units are produced, TFC = $1 * 100 = $100. Thus, TVC = TC - TFC = $400 - $100 = $300.

1 mark for the correct option C.

An increase in government spending increases aggregate demand. Higher aggregate demand and infrastructure projects increase employment. Since spending increases with unchanged tax revenue, the budget balance moves towards a deficit.

1 mark for the correct option A.

A tariff protects domestic steel producers from foreign competition, allowing them to increase sales and raise prices, which benefits them. The government also benefits as it receives the tariff revenue. Consumers and domestic steel-using firms suffer from higher prices.

1 mark for the correct option C.

An increase in the export of services represents an inflow of money, which directly increases credits in the current account, thereby reducing the current account deficit.

1 mark for the correct option D.

To find the percentage of the population without access to clean drinking water:

$$\text{Percentage} = \left( \frac{\text{Population without access}}{\text{Total Population}} \right) \times 100$$

$$\text{Percentage} = \left( \frac{0.96\text{ million}}{8.0\text{ million}} \right) \times 100 = 12\%$$

Award 1 mark for the correct percentage: 12% (accept 12).

One reason why a government might reduce a subsidy to domestic agricultural producers is to lower its overall fiscal spending. This reduction in government expenditure can help the government decrease its budget deficit or reallocate these financial resources to other critical public sectors, such as education or infrastructure, which can improve long-term economic development.

1 mark for identifying a valid reason.
1 mark for explaining the reason.

E.g.:
- To reduce government expenditure (1) to help lower a budget deficit / reallocate funds to other public services (1).
- To encourage domestic efficiency (1) as firms are forced to lower costs of production to remain competitive without financial aid (1).

A high rate of inflation makes domestically produced goods more expensive relative to goods from other countries. As a result, domestic exports become less price-competitive in international markets, which leads to a fall in demand for exports and a decline in export revenue, thereby worsening the current account balance.

1 mark for identifying the impact on relative prices (e.g., exports become less price-competitive or imports become relatively cheaper) (1).
1 mark for explaining how this affects export revenue or import expenditure (e.g., leading to lower export sales or higher import spending, worsening the current account balance) (1).

1. **Investing in education and training** (1 mark): This improves the skills, literacy, and technical abilities of the workforce, which raises their human capital and productivity (1 mark).

2. **Improving healthcare services** (1 mark): Better access to healthcare improves the physical and mental health of workers, which reduces absenteeism due to illness and increases their overall efficiency and longevity in the workforce (1 mark).

Award 1 mark for each of the two ways identified, and 1 mark for each explanation.

Ways could include:
* **Providing education / vocational training** (1) to raise skills / literacy / productivity / qualifications (1).
* **Improving healthcare** (1) to reduce sick leave / absenteeism / improve physical fitness and concentration (1).
* **Offering subsidies for apprenticeships / training programs** (1) to encourage firms to upskill their employees (1).
* **Encouraging net immigration of highly skilled workers** (1) to fill skill shortages and raise average quality (1).

### Explanation of the Diagram:
1. **Axes**: The vertical axis should be labelled 'Price' (or 'P') and the horizontal axis should be labelled 'Quantity' (or 'Q').
2. **Original Curves**: A downward-sloping demand curve (D) and an upward-sloping supply curve (S) should intersect at the initial equilibrium price (\(P_1\)) and quantity (\(Q_1\)).
3. **Shift**: An increase in the wages of orange pickers increases the cost of production for orange growers. This causes a decrease in supply, represented by a leftward shift of the supply curve from S to \(S_1\).
4. **New Equilibrium**: The new supply curve \(S_1\) intersects the original demand curve D at a higher equilibrium price (\(P_2\)) and a lower equilibrium quantity (\(Q_2\)).

**Marking Criteria:**
- **Axes**: Correctly labelled price (vertical) and quantity (horizontal) (or P and Q) (1 mark)
- **Original curves**: Correctly labelled downward-sloping demand curve and upward-sloping supply curve (1 mark)
- **Shift**: Supply curve shifted to the left (1 mark)

Based on the data in Table 1.1:
- **Expected relationship:** There is an inverse (negative) relationship between the female labour force participation rate and the fertility rate. As the percentage of females participating in the labour force increases, the fertility rate tends to fall.
- **Supporting evidence:** Yemen has the lowest female labour force participation rate at 6% and a high fertility rate of 3.8 births per woman. Conversely, Singapore has a high female participation rate of 61% and the lowest fertility rate at 1.1 births per woman.
- **Explanation of the expected relationship:** Women who enter the workforce face a higher opportunity cost of child-rearing in terms of foregone wages and career disruption. They also have less time available to care for children, leading them to delay marriage and childbirth or have smaller families.
- **Exception:** Angola is a clear exception to this expected relationship. It has a very high female labour force participation rate of 74% (higher than Singapore and Germany), yet it has the highest fertility rate in the table at 5.3 births per woman.
- **Explanation of the exception:** In developing nations like Angola, a high proportion of female employment is in subsistence agriculture. In these societies, children are often viewed as economic assets (providing labour on farms) rather than financial liabilities. Additionally, there may be limited access to family planning and maternal education.

Award up to 5 marks in total:
- **Expected relationship (1 mark):** Identifies an inverse/negative relationship (as female labour force participation increases, the fertility rate falls, or vice versa).
- **Supporting evidence (1 mark):** Uses data from the table to support the trend (e.g., comparing Yemen's low participation/high fertility with Singapore's high participation/low fertility).
- **Explanation of the expected relationship (1 mark):** Explains why this negative relationship exists (e.g., working women face a higher opportunity cost of having children, have less time for childcare, or delay childbirth to focus on careers).
- **Exception (1 mark):** Identifies Angola as the exception (having a high female participation rate of 74% but also the highest fertility rate of 5.3).
- **Explanation of the exception (1 mark):** Explains why the exception occurs (e.g., high female participation in developing economies is often in subsistence farming where children contribute to agricultural output, or due to a lack of access to education and family planning).

A rise in the exchange rate (appreciation) increases the price of Country A's exports in foreign currencies and decreases the price of imports in the domestic currency.

**Arguments that it will reduce the current account surplus:**
* **Exports become less competitive:** Foreign buyers will find Country A's goods and services more expensive, which is likely to lead to a fall in the quantity demanded of exports and a decline in export revenue (if demand is price-elastic).
* **Imports become more attractive:** Domestic consumers will find imported goods cheaper than domestically produced goods, causing them to switch their spending to imports, which increases import expenditure.
* **Reduction in surplus:** As export revenue falls and import expenditure rises, the net trade balance worsens, shrinking the current account surplus.

**Arguments that it will not reduce the current account surplus:**
* **Inelastic demand:** If Country A's exports are highly specialised or have few substitutes (e.g., advanced technology or luxury goods), demand is price-inelastic. The higher price will lead to an increase in total export revenue. Similarly, if imports are necessities (like oil or food), cheaper prices will not significantly increase the quantity imported, lowering overall import expenditure.
* **Non-price competitiveness:** If the quality, reliability, or brand reputation of Country A's goods is excellent, foreign consumers may continue to buy them despite the higher prices.
* **Growth in foreign markets:** If the economies of key trading partners are growing rapidly, their rising incomes may increase demand for Country A's exports, offsetting the negative price effect of the stronger currency.

**Award up to 4 marks for logical reasons why it might, which may include:**
* A stronger currency makes exports more expensive for foreign buyers (1), leading to a fall in export volume/revenue (1).
* Imports become cheaper for domestic consumers (1), leading to an increase in spending on imports (1).
* This combination of lower export revenue and higher import expenditure will reduce the current account surplus (1).

**Award up to 4 marks for logical reasons why it might not, which may include:**
* If demand for exports is price-inelastic (1), the rise in price leads to a smaller percentage fall in quantity demanded, so export revenue rises (1).
* If demand for imports is price-inelastic (1), cheaper imports lead to a smaller percentage increase in quantity demanded, reducing import expenditure (1).
* Foreign consumers may still buy exports due to high quality/reputation (1), so export volume remains stable (1).
* Global economic growth/incomes may be rising (1), offsetting the effect of the higher exchange rate on exports (1).

An increase in interest rates is a key tool of contractionary monetary policy used to curb inflationary pressures.

**Arguments that it will reduce the rate of inflation:**
* **Reduction in consumer spending:** Higher interest rates make borrowing more expensive, reducing the take-up of consumer credit/loans. It also increases the reward for saving, encouraging consumers to save rather than spend, which reduces aggregate demand (AD).
* **Reduction in business investment:** The cost of borrowing for capital equipment and expansion rises, leading firms to delay or reduce investment projects, further lowering AD.
* **Lowering demand-pull inflation:** As consumer spending and investment fall, the overall level of demand in the economy decreases, easing upward pressure on prices.
* **Exchange rate effect:** Higher interest rates can attract hot money flows, causing the exchange rate to rise. This makes imported raw materials and finished goods cheaper, reducing cost-push inflation.

**Arguments that it will not reduce the rate of inflation:**
* **Cost-push inflation:** If inflation is caused by supply-side shocks, such as rising global energy or commodity prices, higher domestic interest rates will do little to reduce these international costs.
* **High consumer/business confidence:** If the economic outlook is very optimistic, consumers and businesses may continue to borrow and spend despite higher interest rates.
* **Cost-push impact on domestic firms:** Higher interest rates increase the interest costs of firms with existing variable loans, which might lead them to increase prices to maintain profit margins, causing cost-push inflation.
* **Time lags:** Monetary policy changes can take up to 18 to 24 months to fully influence economic activity, during which inflation may continue to rise.

**Award up to 4 marks for logical reasons why it might, which may include:**
* An increase in interest rates makes borrowing more expensive (1), reducing consumer spending on credit / loans (1).
* It increases the incentive to save (1), leading to less consumption / consumer expenditure (1).
* Firms may reduce investment as the cost of borrowing for capital equipment rises (1).
* Aggregate demand / total demand falls (1), reducing demand-pull inflation (1).
* The exchange rate may rise as foreign investors seek higher returns (1), making imports cheaper and lowering imported inflation (1).

**Award up to 4 marks for logical reasons why it might not, which may include:**
* If consumer and business confidence is very high (1), borrowing and spending may continue to rise despite higher rates (1).
* Higher interest rates increase the costs of production for firms that rely on borrowing (1), leading to cost-push inflation (1).
* There may be a time lag (1); it can take up to two years for interest rate changes to fully affect the economy (1).
* Inflation may be caused by global supply-side shocks (e.g. rising oil prices) (1), which domestic monetary policy cannot control (1).

Opportunity cost is defined as the cost of the next best alternative foregone when a choice is made (1). An example is when a student chooses to study for an exam instead of going to the cinema; the opportunity cost of studying is the enjoyment of the movie (1).

1 mark for the correct definition: the next best alternative given up / foregone when a choice is made.
1 mark for a relevant, clear example.

Frictional unemployment is defined as short-term unemployment that occurs when workers are in the process of moving between jobs or searching for new ones (1). An example is a university graduate who is currently searching for their very first employment opportunity (1).

1 mark for the correct definition: temporary/short-term unemployment that arises when workers are in transition between jobs or looking for their first job.
1 mark for a relevant example (e.g., career changer, recent graduate).

An import quota is a non-tariff trade barrier that sets a physical restriction or limit on the quantity of a specific product that can be legally imported into a country during a specified period (1). An example is a government restricting foreign passenger vehicle imports to 100,000 units per year (1).

1 mark for the correct definition: a physical limit or restriction on the quantity or value of imports of a specific good entering a country.
1 mark for a relevant example.

A depreciation of a country's currency means its value falls relative to other currencies. This makes exports cheaper for foreign buyers, which increases the demand for exports and raises export revenue (1 mark). At the same time, imports become more expensive for domestic buyers (1 mark). This discourages domestic consumers from buying imports, leading to a fall in import expenditure (1 mark). Since export revenue increases and import expenditure decreases, the gap between them narrows, thereby reducing the current account deficit (1 mark).

Award 1 mark for each of the following logical steps (up to a maximum of 4 marks):
- Explain that depreciation makes exports cheaper in foreign currency (1 mark).
- Explain that cheaper exports lead to an increase in export demand and/or export revenue (1 mark).
- Explain that depreciation makes imports more expensive in local currency (1 mark).
- Explain that more expensive imports lead to a fall in import demand and/or import expenditure (1 mark).
- Note: Recognition of the net effect on the current account (export revenue increases relative to import expenditure) (1 mark).

Fixed costs are costs that do not change with the level of output, such as rent (1 mark). Average fixed cost (AFC) is calculated as total fixed cost divided by the quantity of output produced (1 mark). As the firm's output increases, the constant total fixed cost is spread over a larger number of units (1 mark). Consequently, the average fixed cost per unit continuously declines as output rises (1 mark).

Award 1 mark for each of the following points (up to a maximum of 4 marks):
- Define fixed cost (a cost that does not vary with changes in output) (1 mark).
- State the formula or definition of average fixed cost (total fixed cost divided by output) (1 mark).
- Explain that as output increases, the total fixed cost is divided/spread over a larger number of units (1 mark).
- State that average fixed cost continuously falls/declines as output increases (1 mark).

First, the government can invest in education and vocational training programs (1 mark). This improves the skills of the workforce, making them more productive and adaptable to new jobs, which reduces structural unemployment (1 mark). Second, the government can reduce income taxes (1 mark). This increases the net financial reward of working, which incentivises inactive or unemployed individuals to actively seek and accept job vacancies, reducing frictional unemployment (1 mark).

Award up to 4 marks. For each of the two ways explained:
- 1 mark for identifying a valid supply-side policy (e.g., spending on education/training, deregulation, cutting unemployment benefits, reducing income tax, subsidies for business relocation to depressed regions).
- 1 mark for explaining how this policy reduces unemployment (e.g., training matches workers' skills with structural vacancies; tax cuts increase the opportunity cost of remaining unemployed; deregulation lowers business costs, enabling firms to expand output and hire more workers).

Note: Maximum of 2 marks per way explained.

A depreciation of a country's exchange rate lowers the price of its currency in terms of foreign currencies. This makes exports cheaper for foreign buyers, which is likely to increase the quantity demanded and total export revenue, assuming the demand for exports is price-elastic. Conversely, depreciation makes imported goods more expensive in the domestic market. This price rise discourages domestic consumers from buying foreign goods, leading to a decrease in import volumes and a fall in import expenditure, assuming the demand for imports is price-elastic. Since the current account deficit is largely driven by a trade deficit, the combination of rising export revenue and falling import expenditure will narrow the trade gap, thereby reducing the current account deficit.

Award up to 6 marks for coherent analysis: - Depreciation reduces the price of exports in foreign currency (1 mark). - This leads to an increase in the demand for and volume of exports (1 mark). - Depreciation increases the domestic price of imports (1 mark). - This leads to a decrease in the demand for and volume of imports (1 mark). - If demand for exports and imports is price-elastic, export revenue rises and import expenditure falls (1 mark). - This improves the trade balance in goods and services, which reduces the current account deficit (1 mark).

Structural unemployment occurs when there is a mismatch between the skills workers possess and the skills required for available jobs, often due to technological progress or the decline of traditional industries. When a government increases spending on education and training, it funds programs that teach new, relevant skills to unemployed individuals. This increases the occupational mobility of the labor force, allowing workers to transition from declining industries to expanding sectors (such as technology or healthcare). Retraining makes workers more productive and adaptable, making them more attractive to employers and enabling them to fill existing job vacancies, which directly reduces structural unemployment.

Award up to 6 marks for coherent analysis: - Identifies structural unemployment as a mismatch of skills or occupational immobility (1 mark). - Government spending on training and education provides workers with new or updated skills (1 mark). - This increases the occupational mobility of workers (1 mark). - Workers can transition from declining industries to expanding industries (1 mark). - Increases labor productivity, making workers more employable (1 mark). - Helps fill vacancies, reducing the skills gap and structural unemployment (1 mark).

As a firm grows in size and increases its scale of production, it can experience internal economies of scale, which reduce its average cost of production. Growth leads to financial economies because larger firms are generally perceived by banks as more stable and less risky. Consequently, they can borrow larger sums of money and secure loans at lower interest rates than smaller competitors, reducing their borrowing costs. Growth also enables technical economies because larger firms have the financial strength to purchase and utilize highly advanced, specialized machinery and technology. This sophisticated capital increases productive efficiency and output, spreading fixed costs over a much larger volume of production, which significantly lowers the average cost per unit.

Award up to 6 marks for coherent analysis: - Explains that internal economies of scale reduce average cost as the firm grows (1 mark). - Financial economies: Larger firms are seen as less risky by lenders (1 mark). - This allows them to borrow larger amounts (1 mark) at lower interest rates (1 mark). - Technical economies: Larger firms can afford specialized or large-scale machinery and technology (1 mark). - This increases productivity and efficiency (1 mark) and spreads fixed costs over a larger output, lowering per-unit cost (1 mark).

Arguments in favor of a maximum price on basic food items: It makes essential food items affordable for low-income consumers, helping to reduce absolute poverty and malnutrition. It prevents exploitation by firms with monopoly power who might artificially restrict supply to charge excessively high prices. It can help control inflation expectations for key essential household purchases. Arguments against a maximum price on basic food items: It creates a market shortage because the quantity demanded exceeds the quantity supplied at the maximum price (which is set below the market equilibrium). This shortage can lead to the emergence of informal or black markets where the goods are sold illegally at much higher prices. It reduces profit margins for agricultural producers and food suppliers, which may discourage production, causing some firms to exit the market and worsening the shortage in the long run. The government may have to incur significant costs to monitor and enforce the price ceiling, or provide subsidies to farmers to maintain supply, carrying a high opportunity cost for public funds.

Level 3 (6-8 marks): A reasoned discussion that accurately examines both sides of the economic argument, utilizing clear and logical analysis of price ceilings, shortages, and consumer/producer welfare. There is a thoughtful evaluation of the impacts on low-income households vs market efficiency. Level 2 (3-5 marks): A reasoned discussion that explains some relevant points, but may be one-sided or lack depth in economic concepts. Level 1 (1-2 marks): A simple attempt with basic definitions or unsupported statements about price changes.

Arguments that depreciation will improve the current account: A depreciation makes a country's exports cheaper in terms of foreign currency, increasing foreign demand and export sales volume. It makes imports more expensive in terms of domestic currency, discouraging domestic consumers from buying imports and shifting consumption to domestically produced goods. If the sum of the price elasticities of demand for exports and imports is greater than one (the Marshall-Lerner condition), the total export revenue will rise and total import expenditure will fall, improving the current account balance. Arguments that depreciation may not improve the current account: In the short run, demand for exports and imports tends to be price-inelastic, which can temporarily worsen the current account deficit before it improves (the J-curve effect). If the country relies heavily on imported raw materials or energy, depreciation will raise domestic production costs, leading to cost-push inflation and eroding the price competitiveness of its exports. Other countries may respond with competitive devaluations or trade barriers, nullifying the initial price advantage.

Level 3 (6-8 marks): A reasoned discussion that accurately examines both sides of the economic argument, making use of trade elasticities (Marshall-Lerner condition), price competitive effects, and potential limitations like inflation or retaliation. Level 2 (3-5 marks): A reasoned discussion that explains some relevant points, but may be one-sided or lack depth in exchange rate mechanics. Level 1 (1-2 marks): A simple attempt identifying the basic direction of price changes without clear link to current account revenues.

Arguments that spending on education is highly effective: It increases the skills, qualifications, and productivity of the workforce, directly targeting structural unemployment by reducing occupational immobility. A more skilled workforce attracts foreign direct investment (FDI), leading to long-term job creation. It enables workers to adapt more quickly to technological progress and structural shifts in the economy. Arguments that it may not be the most effective policy: Education spending has a significant time lag; it takes many years for children and young adults to enter the workforce with improved skills, meaning it cannot solve short-term unemployment. There is a high opportunity cost, as these government funds cannot be spent on immediate job-creation policies, infrastructure, or direct corporate subsidies. It does not address cyclical unemployment, which is caused by a general lack of aggregate demand and requires demand-side policies (fiscal or monetary expansion). Alternative supply-side policies, such as reducing labor market regulations or lowering income taxes, may provide faster and more direct incentives for firms to hire and individuals to work.

Level 3 (6-8 marks): A reasoned discussion that accurately examines both the strengths of education spending on structural unemployment and its limitations (time lags, opportunity costs, mismatch issues), comparing it to other demand-side or supply-side alternatives. Level 2 (3-5 marks): A reasoned discussion that explains some relevant points on education and jobs, but may be one-sided or lack contrast with other policies. Level 1 (1-2 marks): A simple attempt stating basic points about schools or general employment.
