2025 Cambridge IGCSE Economics (0455) 模拟试题及答案详解

The opportunity cost of a decision is the value of the next best alternative foregone. Since the student's second choice was working at the supermarket and earning $50, the opportunity cost of choosing to study is the $50 in foregone earnings.

1 mark for the correct option (C).

According to the law of demand, a decrease in price leads to an increase in the quantity demanded. Because the absolute value of the PED is less than 1 (0.4), demand is price inelastic. This means the percentage increase in quantity demanded is smaller than the percentage decrease in price, leading to a decrease in total revenue.

1 mark for the correct option (C).

Acting as the government's bank and executing monetary policy (such as issuing currency and acting as a lender of last resort) are unique functions of a central bank. Commercial banks deal with retail and business customers by accepting deposits and providing loans or mortgages.

1 mark for the correct option (A).

A trade union's bargaining power is enhanced when a firm's profits are rising rapidly, as the employer has a greater ability to pay higher wages without risking business survival. High unemployment, price-elastic product demand, or low union density reduce union leverage.

1 mark for the correct option (D).

Supply-side policies aim to increase long-run aggregate supply and productive capacity. Subsidies for R&D encourage innovation, technological progress, and efficiency, shifting the PPC outwards. Reducing healthcare or training spending, or raising corporation tax, would likely reduce or hinder productive capacity.

1 mark for the correct option (C).

Relative poverty refers to inequality of income within a society. Reducing the income tax rate for high earners increases their disposable income, widening the gap between high-income individuals and low-income individuals. This results in an increase in relative poverty.

1 mark for the correct option (B).

A depreciation of country X's currency means that foreign buyers need less of their own currency to purchase country X's currency. Therefore, the price of country X's exports in foreign currency falls, making them more competitive. This typically increases export volume and increases import prices, potentially causing inflation.

1 mark for the correct option (C).

An increase in the quality and competitiveness of domestic exports will increase foreign demand for these goods, raising export revenue. This directly increases the value of credit items on the current account, narrowing the current account deficit. The other options would either reduce exports or increase imports, worsening the deficit.

1 mark for the correct option (D).

Opportunity cost is defined as the next best alternative foregone. Since the government chose to build a hospital, the opportunity cost is the benefit that would have been gained from the single best alternative option that was not chosen (such as upgrading the national rail network), rather than all alternative options combined or the financial outlay itself.

1 mark for the correct answer (C).
0 marks for incorrect options.

A point inside the PPC indicates that resources are unemployed or used inefficiently. A decrease in unemployment means that resources are being used more fully, which results in the production point moving closer to the PPC frontier. The PPC itself only shifts when there is a change in the total maximum potential productive capacity of the economy.

1 mark for the correct answer (A).
0 marks for incorrect options.

Commercial banks are retail institutions that provide services directly to consumers and businesses, such as offering personal loans and mortgages. Central banks act as lenders of last resort, issue banknotes, and manage national monetary systems, but they do not deal directly with individuals in the general public.

1 mark for the correct answer (C).
0 marks for incorrect options.

VAT is an indirect tax because it is levied on expenditure rather than income or wealth. Personal income tax is a direct tax because it is levied directly on the income of individuals. Therefore, the increase in VAT is an indirect tax change, and the reduction in income tax is a direct tax change.

0 marks for incorrect options.

Wages are determined by demand and supply in the labour market. An increase in the productivity of software engineers raises the demand for their labour, which drives their relative wages higher. Increases in graduate supply or lower demand for software would lower engineers' wages, while occupational mobility would reduce wage differences.

1 mark for the correct answer (D).
0 marks for incorrect options.

Spending on holidays abroad is an import of services, which represents an outflow of money and is recorded as a debit. Profits sent out of the country represent an outflow of primary income, which is also a debit on the current account. Therefore, both transactions are recorded as debits.

1 mark for the correct answer (B).
0 marks for incorrect options.

Cost-push inflation is caused by rising costs of production that shift aggregate supply to the left. An increase in the world price of imported oil raises energy and transport costs across the economy, leading directly to cost-push inflation. Lower interest rates or lower taxes would instead stimulate demand, causing demand-pull inflation.

1 mark for the correct answer (B).
0 marks for incorrect options.

The HDI is a composite index measuring education (literacy and school enrolment), health (life expectancy), and income (real GDP per head). If real GDP per head remains the same, HDI can still increase if there are improvements in education or health, such as an increase in literacy and school enrolment rates.

1 mark for the correct answer (B).
0 marks for incorrect options.

Scarcity arises because human wants are infinite, but the resources (factors of production) available to satisfy those wants are finite/limited.

Award 1 mark for the correct option (B).

Opportunity cost is the benefit foregone from the next best alternative. In this case, the next best alternative is the job as an office administrator. If the salary of the office administrator job falls, the value of what is foregone decreases, reducing the opportunity cost.

Award 1 mark for the correct option (D).

An outward shift of the PPC represents an increase in the productive potential of the economy. Raising the retirement age increases the size of the labor force, which expands productive potential.

Award 1 mark for the correct option (B).

Percentage change in price = \(\frac{12 - 10}{10} \times 100 = 20\%\).
Percentage change in quantity demanded = \(\frac{90 - 100}{100} \times 100 = -10\%\).
PED = \(\frac{-10\%}{20\%} = -0.5\) (absolute value is 0.5).

Award 1 mark for the correct option (A).

If worker productivity increases, the revenue generated per worker rises, which offsets the higher cost of wages without the firm needing to reduce employment.

Award 1 mark for the correct option (C).

Total Cost (TC) = Total Fixed Cost (TFC) + Total Variable Cost (TVC).
TVC = Average Variable Cost \(\times\) Output = \(\$6 \times 100 = \$600\).
TC = \(\$400 + \$600 = \$1000\).

Award 1 mark for the correct option (C).

Vocational training schemes improve the skills and quality of the labor force, making workers more employable and addressing structural mismatch in the labor market. This shifts the long-run aggregate supply curve outwards.

Award 1 mark for the correct option (B).

The US dollar buys more Euros over time (from €0.85 to €0.90), meaning it has appreciated. Conversely, the Euro buys fewer US dollars over time, meaning it has depreciated.

Award 1 mark for the correct option (D).

Opportunity cost is defined as the next best alternative forgone when a choice is made. Here, the next best alternative is improving the rail network. Therefore, the opportunity cost is the benefits lost from not improving the rail network.

1 mark for the correct option (B).

A drought causes the supply curve of cocoa to shift to the left (decreasing supply), which tends to increase price and decrease quantity. A scientific study reporting health benefits shifts the demand curve for cocoa to the right (increasing demand), which tends to increase price and increase quantity. In both cases, the price rises, so the equilibrium price will definitely rise. However, because one change decreases quantity and the other increases it, the overall effect on equilibrium quantity is uncertain without knowing the magnitudes of the shifts.

1 mark for the correct option (A).

Demand-pull inflation is caused by excessive aggregate demand. To reduce it, contractionary policies are needed. Increasing the rate of corporate tax reduces firms' after-tax profits, decreasing investment spending, and potentially increasing final product prices, which reduces consumption. This shifts aggregate demand to the left, reducing demand-pull inflationary pressure. Options A, B, and C are expansionary measures that would increase aggregate demand.

1 mark for the correct option (D).

First, calculate the total variable cost (TVC):
\(\text{TVC} = \text{Average Variable Cost (AVC)} \times \text{Quantity (Q)} = \$4 \times 200 = \$800\).
Next, calculate the total cost (TC):
\(\text{TC} = \text{Total Fixed Cost (TFC)} + \text{Total Variable Cost (TVC)} = \$1,000 + \$800 = \$1,800\).

1 mark for the correct option (B).

Under a floating exchange rate system, the exchange rate is determined by the demand and supply of the currency. A decrease in the foreign demand for a country's exports decreases the demand for that country's currency in the foreign exchange market, causing the currency to depreciate.

1 mark for the correct option (B).

The price elasticity of demand 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 the PED is less than 1 (\(|-0.5| = 0.5 < 1\)), the demand is price inelastic.

1 mark for the correct option (A).

To calculate the total contribution of the oil and gas sector to Norway's GDP:

$$\text{Oil and gas sector contribution} = \text{GDP} \times \text{Sector % of GDP}$$
$$\text{Oil and gas sector contribution} = \$480\text{ billion} \times 22\%$$
$$\text{Oil and gas sector contribution} = \$480\text{ billion} \times 0.22 = \$105.6\text{ billion}$$

Award 1 mark for the correct calculation:

* $105.6 billion (accept 105.6 billion or $105 600 000 000).

According to the last paragraph of the source material:
- The merger was organised 'to avoid one of them collapsing'.
- It 'might also have helped the merged bank to gain greater economies of scale'.
- It 'resulted in some workers losing their jobs'.
- It 'gave the merged bank greater monopoly power'.

Identifying any two of these consequences will earn the 2 marks.

Award 1 mark for each of any two of the following consequences identified from the source material (maximum of 2 marks):
- avoiding one of the banks collapsing (or preventing a loss of confidence in the banking system)
- gaining greater economies of scale
- workers losing their jobs / rising unemployment
- giving the merged bank greater monopoly power

According to the third paragraph of the source material:
- 'Low inflation, along with the production of very high-quality products, may have contributed to this surplus.'
- 'A strong currency has also kept the cost of imported raw materials low in Switzerland.'

Identifying any two of these factors will earn the 2 marks.

Award 1 mark for each of any two of the following factors identified from the source material (maximum of 2 marks):
- low inflation
- production of very high-quality products
- a strong currency (keeping imported raw material costs low)

A subsidy is a financial grant that reduces the costs of production for solar energy producers (1 mark). Lower costs of production encourage firms to increase their supply (1 mark). This increase in supply leads to a lower market price, which increases the quantity demanded and produced by consumers (1 mark).

1 mark for explaining that a subsidy reduces the costs of production for producers. 1 mark for explaining that lower costs lead to an increase in supply / shift the supply curve to the right. 1 mark for explaining that this lowers the price, which increases the quantity demanded/produced.

A strong currency increases the external value of the domestic currency (1 mark). This makes imported raw materials cheaper for domestic firms to purchase (1 mark). As Swiss firms import a significant amount of raw materials, this reduction in import prices lowers their total/average costs of production (1 mark).

1 mark for explaining that a strong currency increases the external value of the currency / makes imports cheaper. 1 mark for explaining that this lowers the price of imported raw materials. 1 mark for linking the cheaper raw materials to a reduction in the firms' overall costs of production.

A correct diagram should feature:
1. **Axes:** Vertical axis labelled 'Price' (or 'P') and horizontal axis labelled 'Quantity' (or 'Q').
2. **Original Curves:** A downward-sloping demand curve (labeled 'D' or 'D1') and an upward-sloping supply curve (labeled 'S' or 'S1') intersecting at the initial equilibrium point, with dotted lines extending to the axes showing initial price ($P_1$) and quantity ($Q_1$).
3. **Curve Shift:** A new supply curve (labeled 'S2') shifted parallel to the left/upwards, representing the increased cost to producers due to the indirect tax.
4. **New Equilibrium:** Dotted lines extending from the new intersection point of S2 and D to show the higher equilibrium price ($P_2$) and the lower equilibrium quantity ($Q_2$).

Award marks as follows:
- **Axes correctly labelled** – price and quantity or p and q (1 mark)
- **Original demand and supply curves correctly labelled** (1 mark)
- **New supply curve shifted to the left** (1 mark)
- **Equilibriums shown** – by lines $P_1$ and $Q_1$ and $P_2$ and $Q_2$ or equilibrium points marked as $E_1$ and $E_2$ (1 mark)

1. **Identify the expected relationship:** Generally, there is a positive / direct relationship between Zetaland's real GDP growth rate and its inflation rate (as GDP growth rises, the inflation rate also tends to rise).
2. **Provide supporting evidence:** From 2018 to 2019, GDP growth rose from 3.5% to 4.2% while inflation rose from 1.5% to 2.0%. Similarly, in 2020, both fell (GDP growth to -1.5% and inflation to 0.5%), and in 2021, both rose significantly.
3. **Explain the economic reason:** Higher real GDP growth indicates expanding economic activity and rising aggregate demand, which puts upward pressure on prices (demand-pull inflation).
4. **Identify the exception:** In 2022, the relationship became inverse / negative, as real GDP growth fell sharply to 1.0% while the inflation rate rose to its highest level of 4.5%.
5. **Explain the exception:** This exception was caused by supply-side / cost-push factors (such as rising energy costs), which reduced output and growth while simultaneously driving up price levels (stagflation).

Award marks for the following points (up to a maximum of 5 marks):
* **Expected relationship (1 mark):** Identifies a generally positive/direct relationship between real GDP growth and inflation.
* **Supporting evidence (1 mark):** Cites relevant data from 2018–2019, 2020, or 2021 to show both variables moving in the same direction.
* **Economic analysis of the relationship (1 mark):** Explains that higher GDP growth reflects rising aggregate demand, causing demand-pull inflation.
* **Exception (1 mark):** Identifies 2022 as an exception where GDP growth fell (to 1.0%) but inflation rose (to 4.5%).
* **Analysis of the exception (1 mark):** Explains that the 2022 exception was due to supply-side/cost-push inflation (e.g., energy shocks reducing growth while increasing prices).

Reasons why a transition to renewable energy sources may benefit Swiss businesses:
- Subsidies provided by the government (such as the solar energy subsidies) can lower the costs of production for energy producers and potentially lower electricity prices for local businesses in the long term.
- Reduces dependence on imported non-renewable energy sources, protecting domestic businesses from global supply shocks and price volatility.
- Boosts the reputation and green credentials of businesses, which can attract environmentally conscious consumers and increase sales.
- Fosters innovation and creates new market opportunities in the renewable energy, construction, and technology sectors.

Reasons why a transition to renewable energy sources may not benefit Swiss businesses:
- High initial capital expenditure/setup costs are required for businesses to upgrade equipment or install solar panels.
- Renewable energy sources like solar can be intermittent and less reliable (dependent on weather conditions), potentially causing disruptions to manufacturing processes.
- Subsidies are funded by taxpayers, which could lead to higher corporate taxes in the future, raising overall business costs.
- The opportunity cost of government spending on energy subsidies means less public investment in other vital business infrastructure, such as transport links or digital networks.

Award up to 4 marks for logical reasons why it might benefit Swiss businesses:
- Lower energy costs in the long run / subsidy effects (1)
- Protection from global supply chain shocks / energy price spikes (1)
- Positive corporate image / attraction of customers (1)
- Job creation / business growth in the green sector (1)

Award up to 4 marks for logical reasons why it might not benefit Swiss businesses:
- High initial transition and equipment costs (1)
- Potential instability or unreliability of green energy supply (1)
- Risk of higher taxation to fund government green subsidies (1)
- Opportunity cost of government spending (less focus on other business-friendly infrastructure) (1)

Note: A maximum of 4 marks can be awarded for a one-sided argument.

Reasons why a strong Swiss franc is beneficial for Swiss households:
- Increases purchasing power for imported consumer goods, making them cheaper and raising the household standard of living.
- Reduces the cost of foreign travel/holidays for Swiss residents.
- Lowers the cost of imported raw materials and energy for Swiss firms, which can be passed on to households in the form of lower retail prices (reducing domestic inflation).

Reasons why a strong Swiss franc is not beneficial for Swiss households:
- Makes Swiss exports more expensive to foreign buyers, which can lead to a fall in demand for Swiss products.
- A drop in export demand may force businesses to reduce production, leading to job losses or wage cuts for household members employed in export industries.
- Deters foreign tourists from visiting Switzerland due to high prices, negatively impacting households whose livelihoods depend on tourism and hospitality.

Award up to 4 marks for logical reasons why a strong currency is beneficial to households:
- Cheaper imports / lower prices for consumer goods (1)
- Increases real household income / purchasing power (1)
- Cheaper foreign travel / tourism for Swiss residents (1)
- Lowers costs of imported raw materials, reducing domestic cost-push inflation (1)

Award up to 4 marks for logical reasons why a strong currency might not be beneficial to households:
- Decreases international competitiveness of Swiss exports (1)
- Potential rise in unemployment / job losses in exporting firms (1)
- Lower wages or reduced hours for workers in export-reliant sectors (1)
- Negative impact on tourism/hospitality jobs within Switzerland (1)

Note: A maximum of 4 marks can be awarded for a one-sided argument.

- Administrative barriers / rules (1)

An increase in interest rates affects households in the following ways:

1. **Increased cost of borrowing:** It becomes more expensive for households to take out loans or use credit cards to buy major items (such as cars, appliances, or houses). This reduces their discretionary spending and overall consumption.
2. **Increased incentive to save:** Financial institutions offer higher interest rates on savings accounts. This encourages households to save a larger portion of their income and defer current spending.
3. **Higher debt-servicing costs:** Households with existing variable-rate loans or mortgages face higher monthly interest payments, reducing their disposable income available for other goods and services.

One mark for each of two effects identified and one mark for each of two explanations:

- **Increased cost of borrowing** (1) leading to reduced consumption/spending on credit-financed purchases (1).
- **Increased incentive to save** (1) leading to households deferring consumption/saving more of their income (1).
- **Higher debt-servicing costs / mortgage repayments** (1) leaving households with less disposable income for discretionary spending (1).

A current account surplus can decrease due to several economic factors:

1. **Appreciation of the national currency:** A stronger exchange rate makes exported goods more expensive for foreign buyers, reducing export demand and revenue. At the same time, it makes imported goods cheaper for domestic consumers, increasing import spending.
2. **Economic growth / rising domestic incomes:** As the national economy expands and household incomes rise, domestic consumers increase their purchase of imports (such as foreign consumer goods and luxury items). Firms also import more foreign raw materials and capital goods, increasing total import expenditure.
3. **High domestic inflation:** If domestic prices rise faster than inflation in partner countries, domestically produced goods become less competitive. This leads to a fall in exports and a switch to relatively cheaper imports.

One mark for each of two reasons identified and one mark for each of two explanations:

- **Appreciation of the exchange rate** (1) making exports relatively more expensive and imports cheaper, thus reducing net exports (1).
- **Rising domestic incomes / economic growth** (1) leading to higher spending on imported consumer and capital goods (1).
- **High domestic inflation** (1) reducing the price-competitiveness of exports and increasing demand for cheaper foreign imports (1).
- **Fall in foreign incomes / global recession** (1) leading to lower demand for the country's exports (1).

A trade union may fail to achieve a wage increase for its members due to several constraints:

1. **Low union density:** If only a small proportion of the firm's or industry's workforce are members of the union, the union lacks collective bargaining power. The employer can continue operations with non-unionised staff, making the threat of a strike less effective.
2. **Poor financial performance of the employer:** If the firm is experiencing falling demand, making low profits, or incurring losses, it cannot afford to pay higher wages. Pressuring the firm for wage increases might lead to firm bankruptcy or job redundancies.
3. **High unemployment in the economy:** A large pool of unemployed workers with similar skills reduces the union's leverage because the employer can easily replace striking workers with cheaper, non-unionised labour.
4. **Restrictive government legislation:** Governments may pass laws that limit the power of trade unions, such as banning strikes in essential public services or requiring complex ballots before taking industrial action.

One mark for each of two reasons identified and one mark for each of two explanations:

- **Low union density / small membership** (1) which reduces the collective bargaining power of the union / makes strike action less disruptive (1).
- **Weak financial position of the employer** (1) meaning the firm cannot afford higher wages without risking closures or redundancies (1).
- **High rate of unemployment / large supply of alternative labour** (1) allowing employers to easily replace unionised workers (1).
- **Restrictive government legislation** (1) which limits the legal ability of the union to take industrial action (1).

A decrease in a country's current account deficit means that the net outflow of money on the current account is reduced. This can happen due to several key factors:

1. An increase in export revenue: If a country's exports become more competitive, foreign demand will rise. This can be caused by a depreciation of the domestic currency (making exports cheaper abroad), improvements in product quality, or higher economic growth in partner countries. Higher export revenue increases the credit items on the current account.

2. A decrease in import expenditure: This occurs when domestic residents buy fewer foreign goods. A domestic recession reduces household incomes, leading to lower spending on imports. Alternatively, the government might impose protectionist trade barriers, such as tariffs, or the currency might depreciate, making imports more expensive. This reduces the debit items on the current account.

3. Increased net primary income: This happens if domestic residents receive more interest, profits, and dividends from foreign assets they own, or if foreign investors earn less from their investments inside the country.

4. Increased net secondary income: An increase in unilateral transfers, such as foreign aid received or remittances sent home by citizens working abroad, will also reduce the deficit.

Award up to 6 marks for a coherent analysis of why a current account deficit might decrease:
- Understanding of current account deficit / net outflow of money (1 mark).
- Analysis of increase in export revenue (1 mark) and its causes, e.g., exchange rate depreciation, quality improvements, or foreign income growth (1 mark).
- Analysis of decrease in import expenditure (1 mark) and its causes, e.g., domestic recession, trade protection, or exchange rate depreciation (1 mark).
- Explanation of how currency depreciation makes exports cheaper and imports more expensive (1 mark).
- Analysis of increase in net primary income (e.g., higher profits/dividends from foreign assets) (1 mark).
- Analysis of increase in net secondary income (e.g., higher remittances or foreign aid) (1 mark).

A trade union's bargaining power determines its success in negotiating better pay and conditions for workers. Several factors can increase this power:

1. High union density: If a large proportion of the workforce belongs to the union, the threat of collective action (such as a strike) is highly credible, as the firm would struggle to operate without them.

2. High skill levels and low availability of substitutes: When union members possess specialized skills, it is very difficult and costly for employers to replace them with non-union workers or automated machinery.

3. Inelastic demand for the final product: If demand for the firm's product is price inelastic, any wage increases won by the union can be passed on to consumers as higher prices without causing a significant drop in sales or profits, making the employer more willing to agree.

4. High firm profitability: A highly profitable employer has more financial capacity to meet wage demands and faces a high opportunity cost from lost production during strikes, making them more likely to settle negotiations quickly.

5. Favourable government legislation: Laws that protect the right to strike, mandate collective bargaining, or limit employer retaliation strengthen the union’s legal and operational standing.

Award up to 6 marks for a coherent analysis of the factors that can increase trade union bargaining power:
- Define/explain trade union bargaining power (1 mark).
- High union density/membership (1 mark) increases the effectiveness/threat of collective action or strikes (1 mark).
- High skill levels / low substitute labor (1 mark) makes it difficult or expensive for employers to replace union workers (1 mark).
- Price inelastic demand for the firm's product (1 mark) allows the firm to pass higher labor costs onto consumers via higher prices (1 mark).
- High firm profitability (1 mark) gives employers more capacity to pay and increases the cost of lost output from a dispute (1 mark).
- Supportive government labor legislation (1 mark).

To reduce unemployment, a government can implement expansionary fiscal policy. This involves using government spending and taxation to stimulate aggregate demand and job creation:

1. Increasing government spending: The government can directly fund public infrastructure projects (such as roads, schools, and energy systems). This directly creates jobs for construction workers, engineers, and project managers. Furthermore, these newly employed workers spend their wages, creating a multiplier effect that stimulates demand and jobs in other sectors of the economy.

2. Decreasing direct taxes:
- Cutting personal income tax: This increases households' disposable income. As a result, consumer expenditure rises, boosting aggregate demand. Firms will respond to this higher demand by expanding output and hiring more workers, reducing demand-deficient unemployment.
- Cutting corporate taxes: This increases firms' retained profits, leaving them with more funds to invest in capital goods and business expansion, which creates long-term employment opportunities.

3. Subsidies: The government can provide subsidies to firms to encourage them to hire unemployed workers or set up business in areas of high structural unemployment.

Award up to 6 marks for a coherent analysis of how fiscal policy can reduce unemployment:
- Identification of expansionary fiscal policy (1 mark).
- Analysis of increased government spending (1 mark) on public infrastructure directly creating jobs (1 mark).
- Explanation of the knock-on / multiplier effect of government spending on wider demand (1 mark).
- Analysis of cutting personal income tax (1 mark) which increases disposable income, consumer demand, and forces firms to hire more labor to meet demand (1 mark).
- Analysis of cutting corporate tax (1 mark) raising post-tax profits and encouraging business investment/expansion (1 mark).
- Analysis of the use of subsidies to encourage hiring/training (1 mark).

### Arguments in favour of infrastructure spending reducing poverty:
* **Job Creation:** Infrastructure projects (e.g., building roads, railway networks, and schools) are often labour-intensive. They directly employ low-skilled workers, raising their disposable income and lifting them out of absolute poverty.
* **Reduced Geographical Immobility:** Better public transport and road connections allow people from isolated, low-income areas to commute to urban areas where more job opportunities are available.
* **Attracting Private Investment:** Improved infrastructure reduces business operating costs, encouraging domestic and foreign firms to invest. This creates long-term employment opportunities, promoting sustainable poverty reduction.
* **Human Capital Development:** Building schools, training centres, and hospitals improves access to education and healthcare. This increases the health, productivity, and skill level of the workforce, enabling them to command higher wages in the future.
* **Lower Living Costs:** Reliable access to electricity, clean water, and telecommunications reduces the daily costs of living for low-income households, increasing their real income.

### Arguments against infrastructure spending reducing poverty:
* **Opportunity Cost:** Funds spent on infrastructure could have been used for direct poverty-relief measures, such as welfare benefits, food subsidies, or free primary healthcare, which provide immediate relief to the poorest citizens.
* **Time Lags:** Infrastructure projects can take several years to plan and construct. This means there is no short-term benefit for those currently in extreme poverty.
* **Temporary Nature of Jobs:** Many construction jobs created are temporary. Once the project is complete, workers may face unemployment and fall back into poverty if no other jobs are available.
* **Inefficient Targeting and Corruption:** Projects might be built in wealthier regions or suffer from corruption and mismanagement, meaning the benefits do not reach the intended impoverished communities.
* **Regressive Financing:** If the infrastructure is funded by regressive indirect taxes (like VAT) or results in high user fees (such as road tolls), it could disproportionately hurt the poor in the short term.

**Level 3 (6–8 marks):** A reasoned discussion which accurately examines both sides of the economic argument, making use of economic information and clear and logical analysis to evaluate economic issues. Both sides of the argument are considered and developed. There is a thoughtful evaluation of economic concepts, terminology, and information appropriate to the question.

**Level 2 (3–5 marks):** A reasoned discussion which makes use of economic information and clear analysis to evaluate economic issues. The answer may lack some depth and development may be one-sided (focusing only on why it will or why it will not reduce poverty). Relevant economic terminology is used.

**Level 1 (1–2 marks):** There is a simple attempt at using economic definitions and terminology. Some reference may be made to economic theory, with occasional or limited understanding.

**Level 0 (0 marks):** No creditable content.

### Arguments in favour of trade unions benefiting the economy:
* **Higher Wages and Living Standards:** Trade unions use collective bargaining to negotiate higher wages and better working conditions for workers. This increases disposable income, boosts consumer spending, and drives economic growth.
* **Increased Productivity:** Higher wages and better working conditions can boost worker motivation and morale. In turn, this can lead to higher productivity and increased total national output.
* **Reduced Income Inequality:** By representing lower-paid workers, trade unions help narrow the wage gap between higher-paid managers and lower-paid staff, leading to a more equitable distribution of income.
* **Improved Workplace Safety:** Unions advocate for improved health and safety standards. This reduces workplace accidents, decreasing the number of working days lost to injury and sickness, which benefits overall economic productivity.
* **Better Communication:** Trade unions provide a structured channel of communication between employers and employees. This can lead to faster resolution of workplace grievances and reduce staff turnover.

### Arguments against trade unions benefiting the economy:
* **Unemployment:** If trade unions succeed in forcing wages above the market-clearing equilibrium level, firms may reduce their demand for labour. This can lead to classical (real wage) unemployment.
* **Wage-Price Spiral and Inflation:** Higher wages increase the cost of production for firms. To maintain profit margins, firms may pass these costs onto consumers in the form of higher prices, leading to cost-push inflation.
* **Loss of Competitiveness:** Elevated labour costs can make domestic goods more expensive relative to foreign-produced goods, worsening the international competitiveness of exports and harming the current account of the balance of payments.
* **Disruption of Production:** If negotiations fail, unions may organize industrial action, such as strikes or go-slows. This directly disrupts production, reduces national output, and can damage investor confidence.
* **Resistance to Change:** Powerful trade unions may oppose the introduction of new technologies, automation, or changes in working practices if they fear job losses, which can hinder long-term economic efficiency.

**Level 3 (6–8 marks):** A reasoned discussion which accurately examines both sides of the economic argument, making use of economic information and clear and logical analysis to evaluate economic issues. Both sides of the argument are considered and developed. There is a thoughtful evaluation of economic concepts, terminology, and information appropriate to the question.

**Level 2 (3–5 marks):** A reasoned discussion which makes use of economic information and clear analysis to evaluate economic issues. The answer may lack some depth and development may be one-sided (focusing only on benefits or only on drawbacks). Relevant economic terminology is used.

**Level 1 (1–2 marks):** There is a simple attempt at using economic definitions and terminology. Some reference may be made to economic theory, with occasional or limited understanding.

**Level 0 (0 marks):** No creditable content.

### Arguments in favour of depreciation improving the current account balance:
* **Exports Become Cheaper:** A depreciation reduces the price of exports in foreign currency terms. This makes domestic goods more competitive abroad, increasing the volume of exports.
* **Imports Become More Expensive:** The cost of foreign goods increases in domestic currency terms. This encourages domestic consumers to switch from imports to domestically produced substitutes, reducing the volume of imports.
* **Marshall-Lerner Condition:** If the sum of the price elasticities of demand (PED) for exports and imports is greater than 1 (elastic), the increase in export revenue and the decrease in import spending will lead to an overall improvement in the current account.
* **Boosting Domestic Firms:** Higher demand for domestic substitutes increases the output of domestic firms, encouraging them to expand and potentially export more in the long run.

### Arguments against depreciation improving the current account balance:
* **Inelastic Demand in the Short Run (J-Curve Effect):** In the immediate aftermath of a depreciation, demand for imports and exports is often price inelastic. Consumers take time to change habits, and existing trade contracts must be fulfilled. Consequently, the import bill rises while export revenue changes little, worsening the current account in the short run.
* **Cost-Push Inflation:** If the country relies heavily on imported raw materials, energy, or components, their rising cost will increase domestic production costs. This can fuel inflation, which subsequently erodes the initial competitive advantage gained from the depreciation.
* **Global Economic Conditions:** If trading partners are experiencing a recession, their demand for the country's cheaper exports will remain low, preventing any significant increase in export revenue.
* **Retaliation:** Other nations may respond by depreciating their own currencies (competitive devaluation) or introducing tariffs and quotas, neutralizing any potential improvement in the trade balance.
