2026 Cambridge IGCSE Economics (0455) 模擬試題連答案詳解

Opportunity cost is defined as the benefit forgone from the next best alternative given up when making an economic decision. Here, the opportunity cost is the benefit that would have been obtained from the next best alternative use of the $2 million funds.

B is correct [1].
A is incorrect as $2 million is the monetary/financial cost.
C is incorrect as future running costs are additional financial expenses.
D is incorrect because opportunity cost refers only to the single next best alternative forgone, not the sum of all alternatives.

Using the formula: \(\text{PED} = \frac{\text{% change in quantity demanded}}{\text{% change in price}}\). Therefore, \(\text{% change in quantity demanded} = -0.8 \times (-10\%) = +8\%\). Since the demand is price inelastic (\(|\text{PED}| < 1\)), the percentage increase in quantity demanded (+8%) is smaller than the percentage decrease in price (10%), which causes total revenue (Price \(\times\) Quantity) to fall.

A is correct [1].
B is incorrect because when demand is price inelastic, a fall in price reduces total revenue.
C and D are incorrect because the percentage change in quantity demanded is 8%, not 12.5%.

Merit goods (such as healthcare and education) are under-consumed in a market economy because consumers suffer from information failure (imperfect information), leading them to underestimate the private benefits to themselves, while also ignoring the external benefits generated for third parties.

A is correct [1].
B is incorrect as market structure/barriers to entry do not define the specific failure associated with merit goods.
C is incorrect because merit goods generate external benefits, not net external costs.
D is incorrect as this is the characteristic of non-excludability found in public goods.

First, calculate Average Fixed Cost (AFC): \(\text{AFC} = \frac{\text{Total Fixed Cost}}{\text{Output}} = \frac{\$3,000}{500} = \$6\). Then, \(\text{ATC} = \text{AFC} + \text{AVC} = \$6 + \$6 = \$12\).

B is correct [1].
A is incorrect as $6 is only the AFC or AVC.
C is incorrect as it adds total fixed cost to average variable cost ($3,000 + $6).
D is incorrect as $6,000 is the Total Cost ($3,000 + $3,000).

A government budget deficit occurs when government expenditure exceeds tax revenue. Increasing direct taxes raises government tax revenue, and decreasing government spending lowers public expenditure, both of which reduce the budget deficit.

C is correct [1].
A, B, and D are incorrect as cutting taxes or increasing government spending increases the budget deficit.

Cost-push inflation is caused by increases in the costs of production for firms. A sharp rise in the world prices of imported raw materials increases production costs for domestic firms, shifting total supply inward and pushing general price levels up.

C is correct [1].
A and D are causes of demand-pull inflation (increasing total demand).
B is incorrect as currency appreciation makes imported goods and raw materials cheaper, reducing inflation.

The Human Development Index (HDI) is a composite measure composed of three dimensions: a decent standard of living (measured by GNI per capita), a long and healthy life (measured by life expectancy at birth), and knowledge (measured by mean years of schooling and expected years of schooling).

B is correct [1].
A, C, and D are incorrect as they are separate economic/social indicators not used in the formula of HDI.

A decrease in demand for Country X's exports means foreign consumers need to buy less of Country X's currency to pay for goods and services. This shifts the demand curve for Country X's currency to the left in the foreign exchange market, causing the currency to depreciate.

A is correct [1].
B, C, and D are incorrect because a higher interest rate, more incoming tourists, and FDI inflows all increase the demand for Country X's currency, causing it to appreciate.

A shift inwards of the PPC represents a decrease in the productive capacity of the economy. Emigration of skilled workers reduces the size and quality of the labour force (a factor of production), thereby shifting the PPC inwards. Option B and C would increase capacity or demand, and option D represents a movement along the PPC, not a shift.

A is correct (1 mark). B, C, and D are incorrect distractors.

Percentage change in price = \(\frac{8 - 10}{10} \times 100 = -20\%\). Percentage change in quantity demanded = \(\frac{260 - 200}{200} \times 100 = +30\%\). \(\text{PED} = \frac{+30\%}{-20\%} = -1.5\) (or 1.5 omitting the negative sign).

C is correct (1 mark). A calculates percentage change in price over percentage change in quantity (0.67), B and D are arithmetic errors.

Public goods are non-excludable and non-rival. Because it is impossible to prevent non-payers from consuming the good (the free-rider problem), private firms cannot charge a price and make a profit, leading to complete market failure (non-provision).

B is correct (1 mark). Non-excludability causes the free-rider problem.

\(\text{Total Variable Cost (TVC)} = \text{Average Variable Cost} \times \text{Output} = \$4 \times 500 = \$2000\). \(\text{Total Cost (TC)} = \text{Total Fixed Cost (TFC)} + \text{TVC} = \$3000 + \$2000 = \$5000\).

C is correct (1 mark). A is TVC only ($2000), B incorrectly adds average variable cost to total fixed cost ($3004 rounded), D is an arithmetic error.

\(\text{Labour force} = \text{Employed} + \text{Unemployed} = 27\text{ million} + 3\text{ million} = 30\text{ million}\). \(\text{Unemployment rate} = \left(\frac{\text{Unemployed}}{\text{Labour force}}\right) \times 100 = \left(\frac{3}{30}\right) \times 100 = 10.0\%\).

B is correct (1 mark). A incorrectly divides by total working age population (3/40 = 7.5%), C divides unemployed by employed (3/27 = 11.1%).

A direct tax is levied directly on the income or wealth of individuals/firms. A progressive tax takes a higher percentage of income as income rises. An income tax with rising marginal tax brackets is both direct and progressive. Tariffs, sales taxes, and excise duties are indirect taxes.

C is correct (1 mark). Options A, B, and D describe indirect taxes.

The Human Development Index (HDI) measures three core dimensions of human development: a long and healthy life (life expectancy at birth), knowledge/education (mean and expected years of schooling), and a decent standard of living (Gross National Income per head / GNI per capita).

A is correct (1 mark). B, C, and D list other economic indicators not combined in the standard HDI formula.

\(\text{Balance on trade in goods} = 140 - 180 = -40\text{ billion}\).
\(\text{Balance on trade in services} = 75 - 50 = +25\text{ billion}\).
\(\text{Current account balance} = -40 + 25 + 15 - 10 = -10\text{ billion}\) (a deficit of $10 billion).

A is correct (1 mark). B has incorrect sign (+$10bn), C is the balance of goods and services (-$15bn) minus secondary income (-$25bn), D is sum of trade in goods deficit and services surplus without sign adjustment.

An outward shift of the PPC represents an increase in the economy's productive capacity (potential output). Raising the retirement age increases the size of the active labour force, expanding the quantity of available factors of production. Moving resources between goods (B) represents a movement along the PPC. Reducing cyclical unemployment (C) represents a movement from inside the PPC towards the boundary. An increase in demand (D) does not increase maximum potential capacity.

A is correct (1 mark). B, C, and D are incorrect distractors.

Percentage change in price = \(\frac{5.00 - 4.00}{4.00} \times 100 = +25\%\). Percentage change in quantity demanded = \(\frac{8,500 - 10,000}{10,000} \times 100 = -15\%\). Price elasticity of demand (PED) = \(\frac{-15\%}{+25\%} = -0.6\) (expressed as 0.60).

B is correct (1 mark). Calculation: 15% / 25% = 0.60.

A maximum price (price ceiling) set below the equilibrium price makes the good cheaper, leading to an extension in quantity demanded and a contraction in quantity supplied. Because quantity demanded exceeds quantity supplied, an excess demand or shortage is created.

B is correct (1 mark). A, C, and D describe incorrect price ceiling effects.

Total Cost (TC) = Fixed Costs (FC) + Variable Costs (VC) = $12,000 + $18,000 = $30,000. Average Total Cost (ATC) = \(\frac{\text{Total Cost}}{\text{Output}} = \frac{\$30,000}{2,000} = \$15.00\).

C is correct (1 mark). Total cost ($30,000) divided by output (2,000) = $15.00.

Unemployment rate = \(\frac{\text{Number of unemployed}}{\text{Labour force}} \times 100 = \frac{2.4\text{ million}}{30\text{ million}} \times 100 = 8.0\%\).

C is correct (1 mark). 2.4 / 30 * 100 = 8.0%. Option A incorrectly divides by total population.

An increase in interest rates raises the cost of credit, which discourages and decreases consumer borrowing. Higher domestic interest rates attract foreign financial investors seeking higher returns ('hot money' inflows), which increases demand for the domestic currency and causes the exchange rate to appreciate.

A is correct (1 mark). Higher rate reduces borrowing and attracts capital inflows causing currency appreciation.

The Human Development Index (HDI) measures three core dimensions of human development: a long and healthy life (measured by life expectancy at birth), knowledge/education (measured by mean and expected years of schooling), and a decent standard of living (measured by GNI per capita / real GDP per head). Neither income inequality, inflation, nor balance of payments balances form part of the HDI calculation.

B is correct (1 mark). Life expectancy at birth is one of the three core HDI dimensions.

Current account balance = Trade in goods balance ($120bn - $150bn = -$30bn) + Trade in services balance ($60bn - $40bn = +$20bn) + Net primary income (-$10bn) + Net secondary income (+$5bn) = -30 + 20 - 10 + 5 = -$15bn (a deficit of $15bn).

B is correct (1 mark). Sum of balances: -30 + 20 - 10 + 5 = -15bn.

1. Calculate percentage change in price:
\(\frac{8 - 10}{10} \times 100 = -20\%\)

2. Calculate percentage change in quantity demanded:
\(\frac{1,560 - 1,200}{1,200} \times 100 = +30\%\)

3. Calculate PED:
\(\text{PED} = \frac{+30\%}{-20\%} = -1.5\) (or \(1.5\) in absolute terms, indicating price-elastic demand).

4. Calculate total revenue:
- Initial revenue = \(10 \times 1,200 = \$12,000\)
- New revenue = \(8 \times 1,560 = \$12,480\)

Total revenue increased from \(\$12,000\) to \(\$12,480\).

D is correct (1 mark).

A is incorrect: calculates the inverse of PED (20/30 = 0.67) and incorrectly states revenue decreased.
B is incorrect: calculates the inverse of PED (0.67).
C is incorrect: correctly calculates PED of 1.50 but incorrectly states revenue decreased.

1. Calculate Total Fixed Cost (TFC):
\(\text{TFC} = \text{AFC} \times \text{Output} = \$0.40 \times 500 = \$200\)

2. Calculate Total Cost (TC):
\(\text{TC} = \text{TFC} + \text{TVC} = \$200 + \$600 = \$800\)

B is correct (1 mark).

A is incorrect: adds average fixed cost directly to total variable cost ($600 + $0.40).
C is incorrect: miscalculates fixed costs as $500.
D is incorrect: multiplies total variable cost by AFC or adds redundant figures.

An income tax is levied directly on an individual's earnings (direct tax). When the percentage tax rate rises as income increases, the tax takes a higher proportion of income from higher earners, making it progressive.

C is correct (1 mark).

A is incorrect: an excise tax on fuel is an indirect, regressive tax.
B is incorrect: a sales tax is an indirect tax.
D is incorrect: a customs duty is an indirect tax on imported goods.

1. Calculate the number of unemployed people:
\(\text{Number unemployed} = \text{Labour force} - \text{Number employed} = 25\text{ million} - 23\text{ million} = 2\text{ million}\)

2. Calculate the unemployment rate:
\(\text{Unemployment rate} = \left(\frac{\text{Number unemployed}}{\text{Labour force}}\right) \times 100 = \left(\frac{2}{25}\right) \times 100 = 8.0\%\)

B is correct (1 mark).

A is incorrect: divides unemployed by total population (2 / 40 * 100 = 5.0%).
C is incorrect: divides unemployed by the number of employed (2 / 23 * 100 = 8.7%).
D is incorrect: calculates the employment rate (23 / 25 * 100 = 92.0%).

The Human Development Index (HDI) includes three dimensions: health (life expectancy at birth), standard of living (GNI per head adjusted for PPP), and education (measured by mean years of schooling for adults and expected years of schooling for children).

B is correct (1 mark).

A is incorrect: the Gini coefficient measures income inequality, not part of standard HDI.
C is incorrect: inflation rate is a macroeconomic indicator, not an HDI component.
D is incorrect: the current account balance is an external trade measure, not an HDI component.

1. Calculate trade in goods balance: \(\$140\text{bn} - \$180\text{bn} = -\$40\text{bn}\)
2. Calculate trade in services balance: \(\$90\text{bn} - \$60\text{bn} = +\$30\text{bn}\)
3. Calculate total balance of trade in goods and services: \(-\$40\text{bn} + \$30\text{bn} = -\$10\text{bn}\)
4. Add net primary and secondary income:
\(\text{Current account balance} = -\$10\text{bn} + (-\$15\text{bn}) + \$5\text{bn} = -\$20\text{bn}\) (a deficit of \(\$20\text{bn}\)).

A is correct (1 mark).

B is incorrect: only calculates the balance on trade in goods and services (-$40bn + $30bn = -$10bn) omitting primary and secondary income.
C is incorrect: applies incorrect signs to goods deficit and primary income.
D is incorrect: treats the net deficit as a net surplus.

To calculate the unemployment rate:
1. Number of unemployed workers = \(\text{Labour force} - \text{Number employed}\)
\[4.5\text{ million} - 4.14\text{ million} = 0.36\text{ million}\]

2. Unemployment rate = \(\left(\frac{\text{Number of unemployed}}{\text{Labour force}}\right) \times 100\)
\[\left(\frac{0.36}{4.5}\right) \times 100 = 8\%\]

8% or 8 (1)

Note: Accept 8% or 8. Do not accept 0.36 million without calculating the percentage rate.

According to the provided source material, the two challenges faced by solar panel manufacturers in Solaria are:
1. Shortages of skilled technicians.
2. Delays in obtaining imported silicon wafers.

1 mark for each valid point identified directly from the text (maximum 2 marks):
- Shortages of skilled technicians (1)
- Delays in obtaining imported silicon wafers / shortages of imported components (1)

Note: Do not credit points not stated in the source text.

1. Define opportunity cost: The next best alternative foregone (or sacrificed) when making a choice / decision (1 mark).

2. Apply to the source material: Giving up the modernising of public healthcare clinics in order to allocate government spending to offshore wind farms (1 mark).

* The next best alternative forgone / sacrificed (as a result of choosing an alternative) [1]
* Identified example from the source material: modernising / upgrading public healthcare clinics (to build offshore wind farms) [1]

Reason 1: Higher productivity / higher skill level
Identification: Manufacturing workers have higher productivity / higher skill levels due to technical training (1).
Explanation: Higher worker productivity generates greater output per hour, increasing the revenue of manufacturing firms and raising the demand for their labor, which pushes up wage rates (1).

Reason 2: Trade union power / collective bargaining
Identification: Manufacturing workers have stronger trade union membership (1).
Explanation: Trade unions have greater collective bargaining strength to negotiate for higher wages and better working conditions than non-unionised or weakly unionised agricultural workers (1).

Award 1 mark for each valid reason identified (up to 2) and 1 mark for each linked explanation/development (up to 2):

- Higher productivity / skills / training (1): more skilled/productive workers produce higher output/value per hour, increasing firms' demand for their labor / willingness to pay higher wages (1).
- Trade union membership / collective bargaining (1): unions have greater bargaining power to negotiate higher wages / threaten industrial action (1).
- Inelastic supply of skilled labor (1): specialized training takes time to acquire, limiting the supply of manufacturing labor relative to agricultural labor (1).
- Nature of employment / seasonal demand in agriculture (1): agricultural work is seasonal/lower in continuous demand, reducing average earnings/wages (1).

To illustrate the effect on the market for electric bicycles:

1. Axes and Curves: Label the vertical axis as 'Price' (or \(P\)) and the horizontal axis as 'Quantity' (or \(Q\)). Draw a downward-sloping demand curve (\(D\)) and an upward-sloping initial supply curve (\(S_1\)).
2. Initial Equilibrium: Identify the initial equilibrium price (\(P_1\)) and quantity (\(Q_1\)) where \(D\) intersects \(S_1\).
3. Shift in Supply: Both the government subsidy and the advancement in technology reduce firms' production costs, causing the supply curve to shift to the right from \(S_1\) to \(S_2\).
4. New Equilibrium: Identify the new equilibrium where \(D\) intersects \(S_2\). This results in a fall in the equilibrium price (from \(P_1\) to \(P_2\)) and an increase in the equilibrium quantity (from \(Q_1\) to \(Q_2\)).

Award up to 4 marks for the diagram:
- 1 mark: Correct axes labels: Price (\(P\)) on the vertical axis and Quantity (\(Q\)) on the horizontal axis.
- 1 mark: Original demand (\(D\)) and supply (\(S\) / \(S_1\)) curves correctly drawn and labelled, with initial equilibrium price (\(P_1\)) and quantity (\(Q_1\)).
- 1 mark: Supply curve shifted to the right (\(S_2\)) with an arrow or clear label indicating the shift.
- 1 mark: New equilibrium clearly identified, showing a lower equilibrium price (\(P_2\)) and a higher equilibrium quantity (\(Q_2\)).

Note: Do not credit if demand curve is shifted.

Step 1: Identify the main correlation/relationship.
- State that there is an expected positive/direct relationship between annual government spending on healthcare per head and life expectancy at birth (as healthcare spending increases, life expectancy generally increases).

Step 2: Provide supporting data evidence from Table 1.1.
- Compare two countries that fit the trend, including both country names and their specific numerical figures:
- Norway has high healthcare spending per head ($7,850) and a high life expectancy (83.2 years).
- South Africa has low spending per head ($510) and a low life expectancy (65.3 years).
*(Alternative pairing: Costa Rica with $1,120 spending and 80.4 years life expectancy vs Georgia with $420 spending and 73.8 years life expectancy).*

Step 3: Explain the economic reason for the relationship.
- Greater healthcare spending provides better hospital infrastructure, modern medical technology, more trained healthcare professionals, and wider access to medicines and preventative vaccinations, reducing illness/mortality and extending average lifespan.

Step 4: Identify and support an exception/anomaly from the table.
- Provide a clear exception with names and data:
- The United States spends the most ($12,500 per head) but has a lower life expectancy (77.5 years) than Costa Rica ($1,120 per head and 80.4 years) and Norway ($7,850 per head and 83.2 years).
- *Or* Vietnam has the lowest healthcare spending ($190 per head) but has a higher life expectancy (74.5 years) than South Africa ($510 per head and 65.3 years) or Georgia ($420 per head and 73.8 years).

Award up to 5 marks:

- 1 mark for identifying the general / direct / positive relationship (countries with higher healthcare spending per head generally tend to have higher life expectancy).
- 1 mark for supporting evidence from the table showing the expected relationship (must quote country names and data for both variables for at least two countries, e.g. Norway $7,850 and 83.2 years compared to Georgia $420 and 73.8 years).
- 1 mark for an economic explanation of why higher healthcare spending leads to higher life expectancy (e.g. allows provision of better medical facilities / more doctors / preventative medicine / treatment of diseases / lower infant mortality).
- 1 mark for identifying that an exception / anomaly exists.
- 1 mark for supporting evidence from the table for an exception (must quote country names and data for both variables, e.g. the United States has the highest spending per head at $12,500 but a lower life expectancy of 77.5 years than Costa Rica's 80.4 years with $1,120 spending / Vietnam spends $190 per head with a life expectancy of 74.5 years whereas South Africa spends $510 per head with a life expectancy of 65.3 years).

Note: Do not credit data marks if units ($ / years) or country names are missing or incorrect.

Arguments in favour of increasing tariffs:
- Protect domestic production and employment: A tariff increases the price of imported electric vehicles, shifting consumer demand towards domestically produced cars. This protects local manufacturers from foreign competition and prevents structural unemployment in the car industry.
- Improve the current account balance: Reducing the volume of imported vehicles lowers import expenditure, helping to decrease Country X's current account deficit.
- Raise government revenue: The tariff generates tax revenue for the government, which can be reinvested into public services or infrastructure.

Arguments against increasing tariffs:
- Higher prices and reduced consumer choice: Tariffs make imported electric cars more expensive, lowering consumer surplus and potentially slowing down the adoption of green transport.
- Risk of retaliation: Trading partners may respond by placing tariffs on Country X's exports, damaging export industries and worsening the current account balance.
- Domestic inefficiency: Domestic firms shielded from foreign competition may lack incentives to innovate, lower costs, or improve quality, leading to long-term resource misallocation.

Conclusion: Whether the tariff is beneficial depends on the efficiency of domestic carmakers and whether trade partners retaliate. If domestic producers use the protection to modernise, it may support industrial development; otherwise, it could harm consumers and export sectors.

Apply point-based marking with balance (maximum 4 marks for one side):

Why it should (up to 4 marks):
- Protects domestic car manufacturers / employment (1); higher import prices make domestic cars more price competitive, preserving jobs / output (1).
- Reduces expenditure on imports (1); helps reduce Country X's current account deficit / improves the balance of payments (1).
- Generates tax revenue for the government (1); which can be spent on public services / infrastructure (1).
- Protects against dumping / unfair foreign subsidies (1); allows domestic firms time to develop economies of scale (1).

Why it should not (up to 4 marks):
- Leads to higher prices for consumers (1); reduces living standards / real income / consumer choice (1).
- Risk of trade retaliation / trade war (1); other countries may impose tariffs on Country X's exports, reducing export revenue / jobs in export sectors (1).
- Domestic firms may become inefficient (1); lack of competition reduces incentives to lower costs / innovate (1).
- May slow the transition to cleaner transport (1); higher electric vehicle prices could increase reliance on petrol/diesel cars, causing negative environmental externalities (1).

Reward a valid, reasoned conclusion/evaluation based on the analysis provided.

Arguments that an increase in the NMW will reduce poverty:
- Higher earnings for low-paid workers: Workers who retain their jobs will receive higher wage rates, raising their disposable income. This enables them to purchase more basic goods and services, reducing both absolute and relative poverty.
- Increased incentive to work: A higher minimum wage increases the financial reward from employment compared to welfare benefits, encouraging inactive individuals to join the labour force and escape poverty.
- Higher productivity: Better-paid workers may be more motivated, healthier, and experience higher morale, leading to higher labour productivity and potential long-term wage growth.

Arguments that an increase in the NMW will not reduce poverty:
- Risk of unemployment: A higher minimum wage increases firms' labour costs. Employers may reduce demand for low-skilled labour, substituting workers with capital equipment or laying off staff, which increases unemployment and deepens poverty for those affected.
- Cost-push inflation: Higher labour costs may be passed on to consumers as higher prices. If the cost of basic necessities rises, the real purchasing power of low-income households may not improve.
- Does not reach the non-working poor: A higher minimum wage only benefits those in formal employment; it does not directly help the unemployed, elderly pensioners, or workers in the informal economy who represent a large share of the impoverished population.

Conclusion: An increase in the NMW is most effective at reducing poverty if labour demand is inelastic and accompanied by targeted social safety nets and training to support those unable to find work.

Apply point-based marking with balance (maximum 4 marks for one side):

Why it will reduce poverty (up to 4 marks):
- Increases disposable income of low-paid workers (1); enables them to afford essential goods and services / improves living standards (1).
- Reduces the income gap / relative poverty (1); redistributes income towards lower-income households (1).
- Increases the incentive to work / join the labour force (1); reduces dependency on state benefits (1).
- May improve worker motivation / health / productivity (1); making workers more employable and capable of earning higher wages (1).

Why it might not reduce poverty (up to 4 marks):
- May cause unemployment / job losses (1); firms' cost of production rises, causing them to lay off low-skilled workers or cut working hours (1).
- May lead to cost-push inflation (1); firms raise prices of goods/services to protect profit margins, eroding the real purchasing power of the wage increase (1).
- Does not help those outside the labour market (1); e.g. the retired, disabled, or long-term unemployed who do not earn a wage (1).
- May not cover workers in the informal sector / subsistence farming (1); where minimum wage regulations are not enforced (1).

Reward a valid, reasoned conclusion/evaluation based on the analysis provided.

Division of labour refers to the process where workers specialise in performing a particular task or job (1 mark) within a wider production process / dividing production into separate tasks (1 mark).

1 mark for: Specialisation of workers / workers concentrating on a specific task or job.
1 mark for: In the production process / breaking down production into separate tasks/stages.

Monetary policy is government or central bank action using instruments such as interest rates, the money supply, or exchange rates (1 mark) to influence total demand or achieve macroeconomic objectives (1 mark).

1 mark for: Decisions/measures taken by the central bank (or government) regarding interest rates / money supply / foreign exchange rates.
1 mark for: To influence total demand / achieve macroeconomic goals (such as low inflation/stable prices).

A recession occurs when there is a decline in real GDP or negative economic growth (1 mark) occurring over two consecutive quarters / six consecutive months (1 mark).

1 mark for: A fall in real GDP / negative economic growth / decrease in national output.
1 mark for: For two consecutive quarters / for six consecutive months.

1. Working hours and flexibility: Shorter, flexible, or sociable working hours allow workers to achieve a better work-life balance and spend more time with family, making an occupation more attractive.

2. Job security: Occupations with a low risk of redundancy or dismissal provide workers with predictable income and long-term financial certainty, which many value over higher-paying but unstable jobs.

1 mark for identification of each non-wage factor (up to 2).
1 mark for explanation/development of each factor (up to 2).

Points may include:
- Working hours / flexible working arrangements (1) – allows better work-life balance / accommodates family commitments (1);
- Working conditions / health and safety (1) – a safe, comfortable or clean working environment reduces risk of injury or stress (1);
- Job security (1) – lower risk of redundancy / unemployment provides stable long-term income (1);
- Promotion prospects / career progression (1) – provides opportunities to advance within an organisation / gain higher future earnings and status (1);
- Fringe benefits / perks (1) – perks such as free healthcare, company car, or subsidised housing add financial value beyond wages (1);
- Location / commuting distance (1) – shorter travel times reduce transport costs and fatigue (1);
- Level of challenge / job satisfaction (1) – enjoyable or socially meaningful work motivates individuals independently of financial reward (1).

1. To protect infant (sunrise) industries: Newly established domestic industries often lack economies of scale and face high initial average costs. Trade barriers shield them from foreign competition until they become efficient and globally competitive.

2. To reduce a current account deficit: By placing tariffs or quotas on imported goods, the price of foreign goods increases or their quantity is capped, encouraging domestic consumers to switch to locally produced goods and reducing total import expenditure.

1 mark for identification of each reason (up to 2).
1 mark for explanation/development of each reason (up to 2).

Points may include:
- Protect infant (sunrise) industries (1) – allows newly established domestic firms to grow, achieve economies of scale, and become cost-competitive (1);
- Protect declining (sunset) industries / prevent structural unemployment (1) – slows the contraction of traditional industries, giving workers time to retrain and find new jobs (1);
- Prevent dumping (1) – stops foreign firms selling products below cost of production to force domestic rivals out of business (1);
- Reduce a current account deficit (1) – tariffs/quotas make imports more expensive or limited, reducing import spending and improving the balance of payments (1);
- Raise tax revenue (1) – tariffs on imported items generate government revenue to fund public expenditure / infrastructure (1);
- Restrict imports of demerit goods / harmful products (1) – protects public health, safety, or the environment from substandard or dangerous foreign products (1);
- Retaliation against trading partners (1) – responding to protectionist measures imposed by other nations on domestic exports (1).

1. A fall in domestic interest rates: Lower interest rates relative to other countries cause savers and investors to move financial assets abroad in search of higher returns (hot money outflows). This increases the supply of the domestic currency on the foreign exchange market, driving down its price.

2. An increase in demand for imports: If domestic consumers purchase more foreign goods and services, they must sell more of their own currency to buy foreign currencies, which increases the supply of the domestic currency and depreciates its value.

1 mark for identification of each cause (up to 2).
1 mark for explanation/development of each cause (up to 2).

Points may include:
- A decrease in domestic interest rates (relative to other countries) (1) – encourages 'hot money' outflows / foreign investors move funds abroad for higher returns, increasing the supply / reducing demand for the currency (1);
- A fall in demand for exports (1) – foreign buyers purchase less domestic currency to pay for goods, shifting the demand curve for the currency to the left (1);
- A rise in demand for imports (1) – domestic consumers convert more domestic currency into foreign currencies, increasing the supply of the currency on foreign exchange markets (1);
- Higher domestic inflation rate (relative to trading partners) (1) – domestic exports become less price-competitive and imports become cheaper, reducing demand for and increasing supply of the currency (1);
- Speculation / loss of investor confidence (1) – currency traders anticipating a future fall in the currency sell it now, increasing its market supply (1).

When a central bank raises the rate of interest, the cost of borrowing for households and firms increases. This discourages consumers from taking loans for big-ticket purchases and encourages them to save more because the return on savings is higher. As a result, consumer expenditure decreases. At the same time, higher borrowing costs reduce the profitability of planned investment projects, leading firms to cut back on capital spending. The combined fall in consumption and investment leads to a decrease in total demand in the economy. Lower total demand reduces pressure on scarce resources, discouraging producers from raising prices and thereby lowering demand-pull inflation. In addition, higher interest rates may attract foreign financial investment, increasing demand for the domestic currency and causing the foreign exchange rate to appreciate. An appreciated currency makes imported raw materials and goods cheaper, which reduces production costs for domestic firms and lowers cost-push inflation.

A tariff is a tax placed on imported goods. When a government introduces a tariff on foreign cars, the cost to import these vehicles increases. Importers pass on this tax in the form of higher retail prices for imported cars in the domestic market. Because the price of imported cars rises, domestic consumers find them less attractive and substitute towards domestically produced cars or alternatives. This causes a contraction in the quantity demanded for imported cars. Assuming demand for imported cars is price elastic, total consumer expenditure on imported cars decreases. Because expenditure on imports falls, the total value of imported goods decreases. Since the trade in goods is a major component of the current account of the balance of payments, a fall in import expenditure relative to export revenue improves the trade in goods balance, thereby helping to reduce a current account deficit.

Wages in the labour market are determined by the interaction of the demand for and supply of labour. High-skilled workers generally have specialised qualifications, advanced education, or extensive training. This makes their marginal revenue productivity higher, meaning they can produce higher-value output or generate greater revenue for employers. Consequently, firms have a high demand for high-skilled labour. In contrast, the supply of high-skilled labour is limited because acquiring the necessary skills requires substantial time, financial investment, and personal ability, making the supply curve of skilled labour relatively inelastic. With high demand and limited supply, equilibrium wages are pushed upwards. Conversely, low-skilled occupations require little or no formal training, resulting in a large and price-elastic pool of available labour supply. The abundant supply relative to employer demand keeps wage rates lower in low-skilled occupations.

An increase in the national minimum wage (NMW) can benefit an economy in several ways:

1. Higher living standards and reduced poverty: Low-income workers receive higher earnings, which improves their purchasing power and helps reduce relative poverty and income inequality.
2. Increased total demand: Low-income households have a high marginal propensity to consume. Increased wages will lead to higher consumer spending, boosting total demand and encouraging economic growth.
3. Increased labour productivity and morale: Higher wages can increase workers' motivation and reduce staff turnover and absenteeism, which increases output per worker.
4. Higher tax revenues for the government: Higher earnings increase direct tax revenue (income tax) and indirect tax revenue (sales taxes/VAT), while reducing government expenditure on welfare benefits.

However, an increase in the NMW may not benefit the economy due to several potential drawbacks:

1. Risk of unemployment: Higher wages increase the cost of production for firms. If firms cannot afford the higher wage bills, they may lay off workers or substitute labour with capital, causing unemployment, especially among low-skilled workers.
2. Cost-push inflation: Firms facing higher labour costs may pass these costs on to consumers by raising prices, leading to cost-push inflation.
3. Loss of international competitiveness: Higher production costs can make domestically produced goods more expensive compared to foreign alternatives, reducing exports and worsening the current account balance.
4. Impact on small firms: Smaller firms with low profit margins may struggle to absorb higher wage rates, potentially leading to business closures.

In conclusion, whether an increase in the NMW benefits an economy depends on the size of the increase, the elasticity of demand for labour, and whether the wage rise is matched by increases in labour productivity.

Imposing tariffs on imported goods may improve economic performance in the following ways:

1. Protection of domestic industries: Tariffs raise the price of imported goods, making domestically produced substitutes more price-competitive. This helps protect sunrise (infant) industries until they can achieve economies of scale, as well as sunset (declining) industries to avoid sudden large-scale structural unemployment.
2. Improvement of the current account balance: By increasing the cost of foreign goods, domestic demand for imports falls, which can reduce or eliminate a deficit on the trade in goods and services balance.
3. Increased tax revenue for the government: Tariffs are indirect taxes collected on imported goods, providing the government with revenue that can be spent on public services, infrastructure, or reducing fiscal deficits.
4. Protection against dumping: Tariffs prevent foreign producers from selling surplus goods below their cost of production, protecting domestic producers from unfair foreign competition.

However, imposing tariffs may harm economic performance:

1. Higher prices and reduced consumer welfare: Consumers face higher prices for imported products and domestic substitutes, reducing their purchasing power and consumer choice.
2. Retaliation by trading partners: Other countries may respond with retaliatory tariffs, reducing demand for the country's exports, leading to job losses in export industries and worsening the current account balance.
3. Inefficiency and loss of competitiveness: Sheltering domestic firms from foreign competition reduces their incentive to innovate, cut costs, or improve quality, which harms long-term economic efficiency.
4. Higher costs for domestic producers: If imported raw materials and capital equipment are subject to tariffs, domestic manufacturing costs will rise, leading to cost-push inflation.

In conclusion, the success of tariffs depends on the price elasticity of demand for imports, whether trading partners retaliate, and whether protected domestic firms use the temporary protection to become efficient.

Why tariffs might not improve economic performance:
- Increases prices for consumers, lowering real income and living standards (1)
- Risk of retaliation by trading partners, which harms export sectors and increases unemployment (1)
- Reduces competitive pressure, leading to domestic inefficiency and lack of innovation (1)
- Raises costs of imported raw materials and capital goods, increasing production costs and causing cost-push inflation (1)

An increase in government spending on healthcare can increase economic growth in several ways:

1. Healthier and more productive workforce: Better healthcare facilities and treatments reduce illnesses and life-threatening conditions. Workers take fewer sick days, which increases the quality and productivity of labour, boosting the economy's productive capacity and aggregate output.
2. Increased labour force participation: Improved healthcare allows more people, including older individuals or those with chronic ailments, to enter or remain in the workforce, increasing the quantity of labour available for production.
3. Short-run increase in total demand: Government expenditure is a direct component of total demand. Higher spending on hospitals, equipment, and medical staff increases income and employment in the healthcare sector, generating positive multiplier effects across the economy.
4. Encouragement of foreign direct investment: Countries with healthy populations and reliable healthcare infrastructure are often more attractive to multinational companies (MNCs).

However, higher government spending on healthcare may not necessarily increase economic growth:

1. Opportunity cost: Financial resources allocated to healthcare cannot be spent on other growth-promoting areas such as education, transport infrastructure, or research and development.
2. Increased government borrowing or taxation: Funding higher healthcare spending may require higher direct/indirect taxes, which can reduce consumer spending and disincentivise investment, or increase the government budget deficit and national debt.
3. Time lags and inefficiency: The benefits of healthcare investment, such as training new medical professionals or constructing medical centres, take years to materialise. Furthermore, public sector healthcare may suffer from bureaucratic inefficiencies or wastage of resources.
4. Diminishing returns: In high-income countries where healthcare is already advanced, additional spending may yield only small marginal improvements in worker productivity.

In conclusion, increased healthcare spending is likely to foster sustainable economic growth if the funds are managed efficiently and targeted at preventative care, particularly in developing economies where health deficits significantly constrain labour productivity.
