2025 Cambridge IGCSE Economics (0455) Practice Paper with Answers

A decrease in the length of time required to gain professional qualifications lowers the barrier to entry for the occupation, making it quicker and less costly for individuals to qualify, thereby increasing the supply of labour (shifting the labour supply curve to the right). Option A would reduce the attractiveness of the occupation. Option C would make other occupations more attractive, reducing labour supply to this occupation. Option D reduces the net financial reward of working, which would not increase supply.

B is correct (1 mark).

The contribution of each category to the overall percentage change is calculated as: \(\text{Transport contribution} = 10\% \times \frac{20}{100} = 2.0\%\) and \(\text{Food contribution} = 5\% \times \frac{30}{100} = 1.5\%\). All other categories change by 0%, contributing 0%. Summing these contributions gives \(2.0\% + 1.5\% = 3.5\%\).

B is correct (1 mark).

A monopoly is characterised by high barriers to entry and exit, allowing the single dominant firm to maintain market power and earn supernormal profits in the long run. In contrast, perfect competition is defined by free entry and exit (no barriers to entry). Both types of markets may seek profit maximisation, but only monopoly has high barriers to entry.

A is correct (1 mark).

The tax is levied directly on the individual person, making it a direct tax. Because it is a fixed nominal amount ($400), it represents a larger percentage of total income for a low-income person than for a high-income person (e.g. $400 on $4,000 income is 10%, but $400 on $40,000 income is 1%). A tax that takes a decreasing percentage of income as income rises is regressive.

B is correct (1 mark).

Profits, dividends, and interest sent abroad represent an outflow of investment income. In the balance of payments current account, investment income flows are categorized under primary income. Since money is leaving Country X, it is recorded as a debit item on the primary income balance.

C is correct (1 mark).

A reduction in the length or cost of required training lowers the barriers to entry, making it easier and faster for individuals to qualify, which shifts the labor supply curve for that occupation to the right. Job insecurity (A) and higher entry qualifications (C) would reduce labor supply. Higher wages in alternative occupations (D) would attract workers away to other jobs.

B (1 mark)

A is incorrect as reduced job security discourages potential workers.
C is incorrect as higher entry qualifications act as a barrier to entry, decreasing supply.
D is incorrect as higher wages elsewhere increase the opportunity cost of working in this occupation.

To calculate the rate of inflation using weighted price changes:
\(\text{Food contribution} = \frac{30}{100} \times 5.0\% = +1.50\%\)
\(\text{Housing contribution} = \frac{40}{100} \times 2.0\% = +0.80\%\)
\(\text{Transport contribution} = \frac{20}{100} \times (-1.0\%) = -0.20\%\)
\(\text{Recreation contribution} = \frac{10}{100} \times 4.0\% = +0.40\%\)

\(\text{Annual inflation rate} = 1.50\% + 0.80\% - 0.20\% + 0.40\% = 2.50\%\).

B (1 mark)

Award 1 mark for calculating the weighted sum: \((30 \times 5 + 40 \times 2 + 20 \times (-1) + 10 \times 4) / 100 = 250 / 100 = 2.5\%\).

A pure monopoly is characterized by a single seller protected by high barriers to entry, which prevent new firms from entering the industry. Free entry and exit (A), many competing sellers (C), and price-taking behaviour (D) are characteristics of perfectly competitive markets.

B (1 mark)

A, C, and D are characteristics of perfect competition, not monopoly.

A contractionary fiscal policy involves reducing government spending and increasing tax rates (such as income tax). This reduces the budget deficit (by raising tax revenue and lowering public expenditure) and restrains aggregate demand, cooling down inflationary pressures and preventing the economy from overheating.

B (1 mark)

A is incorrect because cutting income tax increases the deficit and stimulates demand.
C is incorrect because raising spending and cutting taxes worsens the deficit and increases overheating risk.
D is incorrect because raising spending expands public expenditure, partially counteracting deficit reduction.

Remittances and unilateral gifts are classified as secondary income (current transfers) because no economic good, service, or factor input is provided in exchange. Since money flows out of Country X, it is recorded as a debit (minus) in Country X's secondary income account, and as a credit (plus) in Country Y's secondary income account.

B (1 mark)

A is incorrect because primary income refers to net investment income and direct compensation of employees working abroad, not unilateral remittances.
C is incorrect because remittances are transfers, not trade in services.
D has the debit/credit entries reversed.

Non-wage factors are non-monetary incentives that influence an individual's choice of occupation. Longer paid annual leave entitlement is a non-wage factor. Basic annual salary, overtime payments, and performance-related bonuses are all wage (financial/monetary) factors.

B is correct (1 mark). A, C, and D are incorrect as they are wage/monetary incentives.

Between Year 2 and Year 3, the CPI increased from 104 to 108, which means the general price level rose (inflation). Between Year 3 and Year 4, the CPI fell from 108 to 106, which means the general price level fell (deflation). Therefore, the price level rose between Year 2 and Year 3, and fell between Year 3 and Year 4.

C is correct (1 mark). A, B, and D are incorrect because CPI index movements directly show the direction of the general price level.

A pure monopoly is characterized by a single supplier dominating the market, protected by high barriers to entry that prevent new competitor firms from entering the industry. Low barriers to entry, identical products across many sellers, and large numbers of competing firms characterize competitive markets.

C is correct (1 mark). High barriers to entry protect a monopoly from competition. A, B, and D describe perfectly competitive or contestable market features.

Reducing personal income tax rates increases consumers' disposable income, which stimulates consumer spending and aggregate demand. Decreasing government spending, raising corporation tax, and increasing VAT are all contractionary fiscal measures that would reduce total demand.

D is correct (1 mark). Personal income tax cuts represent expansionary fiscal policy. A, B, and C are contractionary measures.

Primary income (net income flows) covers cross-border income flows from investments (dividends, interest, profits) and compensation of employees. Secondary income covers unilateral transfers such as foreign aid and remittances with no economic return. Trade in goods and services record exports and imports of physical items and services.

A is correct (1 mark). Dividend returns from overseas investments are recorded under primary income. B is incorrect as secondary income refers to transfers; C and D are incorrect as they cover exports and imports of goods and services.

A decrease in the minimum qualifications required lowers the barriers to entry, enabling more individuals to apply and qualify for jobs in that occupation, thereby shifting the labour supply curve to the right. Reductions in non-wage benefits (A), longer training periods (C), and higher workplace risks (D) would all reduce the attractiveness of the occupation and decrease the supply of labour.

B is correct [1 mark]. A, C, and D are incorrect as they would reduce the supply of labour to the occupation.

Cost-push inflation occurs when aggregate supply decreases due to higher production costs, such as higher prices for imported raw materials. Options A, B, and D represent increases in components of aggregate demand (consumption, net exports, and government spending), which cause demand-pull inflation.

C is correct [1 mark]. A, B, and D are sources of demand-pull inflation.

A pure monopoly is a single seller in a market, protected by high barriers to entry that prevent potential competitors from entering the industry. Monopolies are price setters (not price takers), can make supernormal profits in the long run, and do not compete with many other firms.

A is correct [1 mark]. B describes perfect competition, C describes competitive markets where firms are price takers, and D describes competitive equilibrium.

Higher taxes on corporate profits reduce investment incentives, and reduced government spending lowers aggregate demand. Both are contractionary fiscal policy measures that dampen total economic activity and slow down the rate of economic growth.

B is correct [1 mark]. A and C are unlikely as contractionary fiscal policy tends to increase unemployment and reduce inflation. D is incorrect because increasing taxes and cutting spending reduces a budget deficit.

Trade in goods balance = $120m - $150m = -$30m. Trade in services balance = $80m - $40m = +$40m. Net trade in goods and services = -$30m + $40m = +$10m. Adding net primary income (-$10m) and net secondary income (+$5m): Current account balance = +$10m - $10m + $5m = +$5m (surplus of $5m).

B is correct [1 mark]. Calculation: ($120m - $150m) + ($80m - $40m) - $10m + $5m = +$5m surplus.

An increase in demand for cosmetic dental treatments raises the derived demand for dental surgeons. This shifts the demand curve for their labour to the right, increasing their equilibrium wage relative to hospital cleaners.

B (1 mark) — An increase in the demand for cosmetic dental treatments.

Weights in the CPI reflect the proportion of total household expenditure spent on each category of goods and services, ensuring that price changes in items with higher expenditure have a proportionally greater impact on the measured inflation rate.

A (1 mark) — to reflect the proportion of total consumer expenditure spent on each item.

Using the PED formula: \(\text{PED} = \frac{\% \Delta Q_d}{\% \Delta P} \implies -0.6 = \frac{\% \Delta Q_d}{+10\%} \implies \% \Delta Q_d = -6\%\). Because demand is price inelastic (\(|\text{PED}| < 1\)), the percentage reduction in quantity demanded (\(6\%\)) is less than the percentage rise in price (\(10\%\)), causing total revenue to increase.

B (1 mark) — Quantity demanded decreases by 6% and total revenue increases.

The tax is indirect because it is levied on expenditure on a good and collected by the seller. It is regressive because a fixed specific tax amount represents a larger percentage of income for lower-income households than for higher-income households.

C (1 mark) — indirect and regressive.

Worker remittances sent to relatives abroad are unilateral transfers where no goods, services, or factors of production are received in return. These transfers are classified under secondary income (current transfers) on the current account.

B (1 mark) — secondary income (current transfers).

A decrease in the length of time required for professional training lowers the entry barriers and the opportunity cost of training, encouraging more individuals to enter and qualify for that specific occupation, thereby shifting the labour supply curve to the right.

A (1 mark): Correct identification of a factor shifting the supply of labour outwards. B, C, and D are incorrect because lower non-wage benefits (B) and higher wages in competing jobs (D) decrease labour supply to this occupation, while a universal retirement age increase (C) affects overall economy-wide labour supply rather than shifting supply specifically to this occupation.

Cost-push inflation occurs when the costs of production for firms rise independently of aggregate demand. A rise in world oil prices increases manufacturing and transportation costs across the economy, shifting aggregate supply inwards and raising the general price level.

C (1 mark): Identification of an increase in raw material/input costs leading to cost-push inflation. A lowers import costs; B reduces production costs; D reduces business tax burdens.

Demand is price-inelastic because \(|\text{PED}| < 1\). In accordance with the law of demand, a price rise leads to a decrease in quantity demanded. However, the percentage fall in quantity demanded is smaller than the percentage increase in price, which results in an increase in total revenue.

C (1 mark): Quantity demanded decreases due to the law of demand, and total revenue increases because demand is price-inelastic (percentage rise in price outweighs percentage fall in quantity demanded).

In a perfectly competitive market structure, there is complete freedom of entry and exit for firms in the long run. Goods are homogeneous (precluding advertising and product differentiation), and firms are price takers with no barriers to entry.

B (1 mark): Correct feature of perfect competition. A, C, and D are characteristics associated with imperfect competition, oligopoly, or monopoly.

Primary income consists of net income flows from investment (profits, interest, dividends) and compensation of employees. Dividends received from foreign shares by domestic residents represent an inflow of investment income (a credit item). Tourism spending belongs to trade in services, foreign aid is secondary income (transfers), and manufactured goods belong to trade in goods.

A (1 mark): Correct identification of primary income (investment income/dividends inflow). B is a credit in trade in services; C is a debit in secondary income; D is a credit in trade in goods.

To calculate the balance of trade in goods, subtract the value of imported goods from the value of exported goods:

\(\text{Trade in goods balance} = \text{Goods exports} - \text{Goods imports}\)

\(\text{Trade in goods balance} = \$54\text{ billion} - \$70\text{ billion} = -\$16\text{ billion}\)

The balance of trade in goods is \(-\$16\text{ billion}\) (or a deficit of $16 billion).

-$16 billion / Deficit of $16 billion / -$16bn (1)

Note: Award 1 mark for correct figure with indication of deficit/minus sign and unit (billion).

Capital goods are human-made resources used in the production of other goods and services.

From the extract, examples of capital goods include:
1. High-speed railway line (or rail infrastructure)
2. (Automated) container port terminals
3. (Regional) data centres

1 mark each for any two valid capital goods identified from the text (up to a maximum of 2 marks):
- (High-speed) railway line / rail infrastructure (1)
- (Automated) container port terminals / ports (1)
- (Regional) data centres (1)

Note: Do not accept human resources / labour such as 'software engineers' or 'systems analysts'.

When a central bank raises the interest rate, the cost of taking out loans and mortgages increases, while the incentive to save rises. This leads to a reduction in consumer expenditure and lowers business investment borrowing. Consequently, total demand (aggregate demand) in the economy falls or grows more slowly. With lower overall demand for goods and services, producers are less able to raise prices, reducing demand-pull inflationary pressure.

Award 1 mark for each logical step in the explanation (up to 3 marks):
- Higher interest rates increase borrowing costs / increase the incentive to save (1)
- This leads to a decrease in consumer spending / firm investment / overall demand (1)
- Lower demand reduces demand-pull inflation / dampens upward pressure on the general price level (1)

Government spending on education and training enhances human capital, raising the skills, efficiency, and productivity of the workforce. Higher labour productivity allows domestic firms to produce goods and services at lower average costs and higher quality. This makes domestic products more price-competitive and attractive in international markets. As a result, demand for exports increases (raising export revenue) and domestic consumers buy fewer foreign imports, leading to an improvement in the current account balance.

Award 1 mark for each logical step in the explanation (up to 3 marks):
- Higher expenditure on education improves workforce skills / labour productivity (1)
- Higher productivity reduces unit production costs / improves product quality (1)
- Domestic goods become more internationally competitive / exports increase / imports decrease (1)

A fully labelled market diagram for electric buses must contain the following features:

1. **Axes:**
- Vertical axis labelled *Price* (or *P*).
- Horizontal axis labelled *Quantity* (or *Q*).
- Origin labelled *O* or *0*.

2. **Original Curves and Equilibrium:**
- Downward-sloping demand curve labelled \(D_1\) (or \(D\)).
- Initial upward-sloping supply curve labelled \(S_1\).
- Initial equilibrium point showing equilibrium price \(P_1\) and equilibrium quantity \(Q_1\).

3. **Curve Shift:**
- A subsidy lowers production costs for producers, causing the supply curve to shift to the right from \(S_1\) to \(S_2\) (indicated by a rightward arrow).
- The demand curve remains unchanged.

4. **New Equilibrium:**
- New equilibrium at the intersection of \(D_1\) and \(S_2\).
- Equilibrium price falls from \(P_1\) to \(P_2\).
- Equilibrium quantity rises from \(Q_1\) to \(Q_2\).

1 mark for correctly labelled axes: Price/P on vertical axis and Quantity/Q on horizontal axis (do not accept Price Level or Real GDP/Output). (1)

1 mark for correctly labelled original demand (D/D₁) and supply (S/S₁) curves. (1)

1 mark for supply curve shifted to the right (S₁ to S₂). (1)

1 mark for original and new equilibrium positions clearly indicated, showing price falling (P₁ to P₂) and quantity rising (Q₁ to Q₂). (1)

An analysis of the data in Table 1.1 reveals the following:

1. **General Relationship:** There is generally a positive (direct) relationship between government expenditure on education and adult literacy rates (as spending as a % of GDP increases, literacy rate tends to increase).

2. **Supporting Data Evidence:** For example, Eldoria has the highest expenditure on education at 7.1% of GDP and the highest literacy rate at 99%, whereas Zunari has the lowest expenditure at 2.1% and the lowest literacy rate at 58%. Similarly, Novaria allocates more (5.5%) than Beryllia (4.8%) and achieves a higher literacy rate (92% compared to 86%).

3. **Economic Reasoning:** Higher government spending on education funds more schools, modern learning materials, and better teacher training/salaries, increasing access to basic education and improving literacy skills.

4. **Exception / Anomaly with Data:** Alverna is an exception to this general trend. Alverna spends 6.2% of its GDP on education (more than both Novaria at 5.5% and Beryllia at 4.8%), yet its literacy rate is only 78%, which is lower than both.

5. **Reason for Exception:** This discrepancy may be caused by inefficiency or corruption in the educational budget, spending directed towards higher education rather than primary schooling, high dropout rates due to child labour, or a rapidly growing young population.

Award up to 5 marks for the following points:

- **Expected relationship:** Identification of a direct / positive relationship / as government expenditure on education rises, adult literacy rate tends to rise (1)
- **Supporting evidence:** Data from the table supporting the relationship (e.g. Eldoria spends the most at 7.1% and has the highest literacy at 99%, while Zunari spends the least at 2.1% and has the lowest literacy at 58% / Novaria spends 5.5% and has 92% literacy while Beryllia spends 4.8% and has 86%) (1)
- **Economic explanation of relationship:** Explanation of why higher education spending raises literacy (e.g. higher spending builds more schools / hires better teachers / provides free learning resources, making schooling more accessible/effective) (1)
- **Identification of exception with data:** Alverna is an anomaly / exception (1) as it spends 6.2% of GDP on education but has a lower literacy rate (78%) than Novaria (5.5% spending; 92% literacy) / Beryllia (4.8% spending; 86% literacy) (1)
- **Economic explanation of exception:** Explanation of why an exception exists (e.g. corruption/inefficiency in spending, spending focused on tertiary rather than primary education, high poverty/dropout rates, lag time before spending affects adult literacy) (1)

*(Maximum of 5 marks)*

Why it would benefit low-income workers:
- Higher wage rates lead directly to an increase in earnings / disposable income for those who remain employed.
- Increases purchasing power, allowing workers to buy more basic necessities and improve their standard of living / reduce relative poverty.
- Boosts worker morale and motivation, which can enhance productivity.
- Increases the incentive to work rather than remain unemployed or claim welfare benefits.

Why it might not benefit low-income workers:
- Higher labour costs may cause firms to lay off staff / increase unemployment among low-skilled workers.
- Employers may reduce non-wage benefits or cut overtime and total working hours, leading to unchanged or lower total earnings.
- Firms might pass higher wage costs onto consumers through higher prices (cost-push inflation), which erodes real gains in income.
- Firms may automate processes / replace low-skilled labour with machinery or capital equipment.

Award up to 4 marks for reasons why it would benefit low-income workers and up to 4 marks for reasons why it might not benefit low-income workers (maximum 6 marks in total).

Why it would benefit (up to 4 marks):
- Increases wage rates / earned income of low-paid workers (1).
- Raises purchasing power / standard of living / helps reduce poverty (1).
- Increases work incentive / reduces the gap between wages and unemployment benefits (1).
- Increases motivation / productivity of workers (1).

Why it might not benefit (up to 4 marks):
- May lead to unemployment / job losses as firms cut labour costs (1).
- Firms may reduce working hours / overtime / fringe benefits (1).
- Higher costs of production may cause cost-push inflation / higher prices erode real wage gains (1).
- Firms may substitute capital / machinery for low-skilled labour (1).
- Only applies to formal sector workers / informal sector workers may not receive the legal wage (1).

Non-wage factors refer to non-financial considerations when choosing a job. Two valid examples include: 1. Working conditions (e.g. clean, safe, and comfortable work environment). 2. Job security (e.g. likelihood of keeping the job long term).

1 mark for each valid non-wage factor identified (maximum 2 marks).

Acceptable answers include:
• Working conditions / health and safety (1)
• Job security (1)
• Promotion prospects / career progression (1)
• Hours of work / flexible working hours / shift patterns (1)
• Holiday entitlement / length of annual leave (1)
• Distance / travel time / location (1)
• Job satisfaction / interest in the job / status (1)
• Fringe benefits / perks (e.g. subsidised housing, company car, private healthcare) (1)
• Pension provision / schemes (1)
• Training / education opportunities provided (1)

Cost-push inflation occurs when the total cost of producing goods and services in an economy rises, leading firms to increase prices to maintain profit margins. Two causes are: 1. An increase in wages paid to workers not matched by productivity gains. 2. An increase in the prices of imported raw materials (e.g. oil).

1 mark for each valid cause of cost-push inflation identified (maximum 2 marks).

Acceptable answers include:
• Increase in wages / labour costs / trade union wage demands (1)
• Increase in prices of raw materials / imported components (1)
• Higher indirect taxes (e.g. sales tax, VAT, tariffs) (1)
• Depreciation / devaluation of the domestic currency (raising import costs) (1)
• Higher rent / utility / energy / transport costs (1)
• Natural disasters / supply bottlenecks reducing supply of inputs (1)

The current account of the balance of payments records transactions involving exports and imports of goods and services, as well as cross-border income flows and transfers. Two components are: 1. Trade in goods. 2. Trade in services.

1 mark for each correct component of the current account identified (maximum 2 marks).

Acceptable answers include:
• Trade in goods / visible balance / export and import of goods (1)
• Trade in services / invisible balance / export and import of services (1)
• Primary income / net investment income / profits, interest, and dividends from abroad (1)
• Secondary income / current transfers / government aid / remittances (1)

Note: Do not accept 'capital account' or 'financial account'.

A pure monopoly is a market structure with only one firm producing the entire market supply. Two key features include: 1. A single seller controlling supply in the market. 2. High barriers to entry preventing new firms from entering the industry.

1 mark for each valid characteristic of a monopoly identified (maximum 2 marks).

Acceptable answers include:
• Single seller / one dominant firm / 100% (or high) market share (1)
• High barriers to entry and/or exit (1)
• Price maker / price setter (1)
• Unique product / no close substitutes (1)
• Imperfect / asymmetric knowledge / lack of consumer information (1)
• Can earn supernormal profits in the long run (1)

1. **Greater job security:** Public sector organisations and government departments are funded by taxation and are not driven solely by short-term profit, meaning workers face a lower risk of redundancy during economic downturns.

2. **Better non-wage benefits / working conditions:** The public sector often offers more generous pension schemes, flexible working hours, longer holiday entitlements, or better parental leave arrangements compared to private sector firms.

Award 1 mark for each reason identified (up to 2) and 1 mark for each explanation (up to 2):

* **Greater job security (1):** government organisations rarely go out of business / lower likelihood of being made redundant during economic downturns (1).
* **Generous pension schemes / retirement benefits (1):** state pensions or public sector schemes may be defined benefit / more stable (1).
* **Better working conditions / flexible hours / shorter hours (1):** promotes better work-life balance / lower stress levels (1).
* **More paid holidays / leave entitlements (1):** public employers frequently provide more annual or parental leave than private employers (1).
* **Sense of social purpose / public service motivation (1):** working to help society / provide merit/public goods (e.g. healthcare, education) rather than generating private profit (1).
* **Clearer career progression / pay scales (1):** wages and promotions are often structured by fixed, transparent increments (1).

*Note: Do not award two explanation marks for one identification.*

1. **Delayed consumer spending:** When the general price level falls, households may postpone purchasing durable goods and major items because they expect prices to be even lower in the future. This decrease in consumer expenditure lowers aggregate demand and can lead to slower economic growth or a recession.

2. **Increased real burden of debt:** In a period of deflation, nominal wages and business revenues typically fall, but nominal debt obligations remain fixed. As a result, borrowers find it more difficult to repay loans, leading to higher loan default rates and reduced business investment.

Award 1 mark for each harmful consequence identified (up to 2) and 1 mark for each explanation (up to 2):

* **Delayed consumption / deferred purchases (1):** consumers anticipate future price drops, leading to falling aggregate demand / lower output (1).
* **Increased real burden of debt (1):** nominal debts stay fixed while wages/revenue fall, making it harder for households/firms to service loans / increasing bankruptcies (1).
* **Rise in cyclical unemployment (1):** lower sales and revenue cause firms to cut output and lay off workers (1).
* **Lower profit margins / business investment (1):** falling prices reduce firm revenue, discouraging capital spending and innovation (1).
* **Policy interest rates reaching the zero lower bound (1):** central banks cannot reduce nominal interest rates below zero to stimulate the economy (1).

*Note: Accept 'malign/demand-side deflation' effects. Do not accept beneficial supply-side effects.*

1. **Availability of close substitutes:** If a product has many readily available substitutes, a rise in its price will cause consumers to easily switch to alternative products, making demand price-elastic. If there are few or no substitutes (e.g. electricity or unique medications), consumers must continue buying it, making demand price-inelastic.

2. **Proportion of consumer income spent on the good:** Goods that take up a very small percentage of a consumer's total income (such as salt or matches) have price-inelastic demand because price increases are barely noticeable. In contrast, expensive items taking up a large share of income (such as cars or laptops) have price-elastic demand.

Award 1 mark for each determinant identified (up to 2) and 1 mark for each linked explanation (up to 2):

* **Availability of close substitutes (1):** the more substitutes available, the easier it is for consumers to switch when price rises, making demand more elastic (or converse) (1).
* **Proportion of income spent on the good (1):** goods requiring a large share of income are more price-elastic / small share are more price-inelastic (1).
* **Degree of necessity vs luxury (1):** necessities (e.g. basic food, essential medicine) are price-inelastic whereas luxury goods are price-elastic (1).
* **Time period (1):** in the long run demand is more elastic because consumers have more time to adjust habits / find alternatives (1).
* **Habit-forming / addictive nature of the good (1):** addictive goods (e.g. tobacco) have price-inelastic demand because consumers cannot easily stop buying them (1).
* **Brand loyalty / advertising (1):** strong brand loyalty reduces the willingness of consumers to switch, making demand more inelastic (1).

1. **To discourage the consumption of demerit goods:** Placing higher indirect taxes (such as excise duties on tobacco, alcohol, or sugary drinks) raises their market prices. This reduces consumer demand, mitigating health problems and decreasing the negative externalities imposed on society.

2. **To raise government revenue:** Indirect taxes (such as Value Added Tax / sales tax) are easy and quick to collect over a wide base of goods and services. The additional tax revenue can be used to fund public goods, infrastructure projects, or reduce a fiscal deficit.

Award 1 mark for each reason identified (up to 2) and 1 mark for each explanation (up to 2):

* **Discourage consumption of demerit goods / reduce negative externalities (1):** higher prices reduce demand for harmful products like cigarettes/alcohol, improving public health (1).
* **Increase government tax revenue (1):** funds can be spent on public services (e.g. education/healthcare) or reducing government debt (1).
* **Protect domestic industries / reduce import expenditure (tariffs) (1):** taxing imported goods makes them more expensive relative to domestic alternatives, improving the trade balance (1).
* **Ease of collection / difficult to evade (1):** indirect taxes are paid automatically at the point of sale, making collection cheaper and evasion harder than direct taxes (1).
* **Reduce environmental damage / carbon emissions (1):** environmental taxes penalise polluters and encourage cleaner production methods (1).

Highly skilled workers typically earn higher wages than unskilled workers due to both demand and supply factors in the labour market:

1. **Supply of Labour:**
- The supply of skilled workers is relatively low / limited (1) because acquiring specialised skills requires lengthy education, training, and specific qualifications (1).
- Consequently, the price elasticity of supply of skilled labour is inelastic (1), meaning employers cannot easily find substitutes (1).
- In contrast, unskilled labour requires minimal training, leading to a high / abundant supply of available workers (1).

2. **Demand and Productivity:**
- Skilled workers tend to have higher marginal productivity / generate more output per hour (1), which creates greater revenue and value for employers (1).
- Demand for skilled labour is often derived from high-value added goods or services (1).

3. **Bargaining Power:**
- Skilled workers often possess greater individual or collective bargaining power (1) and are harder to replace, enabling them to negotiate higher wage rates (1).

Coherent analysis which may include the following points (up to a maximum of 6 marks):
- Supply of skilled workers is lower / limited / restricted (1)
- Acquiring qualifications / specialised training takes time and effort (1)
- Supply of skilled workers is relatively inelastic (1)
- Skilled workers have higher productivity / produce higher value output (1)
- Higher demand from employers / firms for specialised skills (1)
- Higher derived demand for skilled goods and services (1)
- Skilled workers are harder to replace / fewer close substitutes exist (1)
- Greater bargaining power of skilled workers / professional bodies (1)
- In contrast, unskilled labour is in elastic / abundant supply (1)
- Lower training barriers mean unskilled workers are easily replaced (1)

Note: Award a maximum of 6 marks. Reward logical chains of analysis.

A period of high inflation can inflict significant damage on an economy in several ways:

1. **Loss of Purchasing Power:**
- High inflation reduces the real purchasing power of money (1). If wages do not rise in line with the price level, real incomes fall (1), reducing consumption and living standards, especially for fixed-income earners and the poor (1).

2. **Reduced International Competitiveness:**
- Domestic goods and services become relatively more expensive compared to foreign alternatives (1). This can lead to a fall in export revenue and a rise in import expenditure (1), worsening the current account deficit on the balance of payments (1).

3. **Business Uncertainty and Lower Investment:**
- Rapidly rising prices create uncertainty regarding future costs, revenues, and profits (1). As a result, firms postpone or cut back on capital investment (1), which hinders long-term productive capacity and economic growth (1).

4. **Additional Costs:**
- High inflation can cause 'menu costs' (costs of reprinting price lists/updating software) and 'shoe-leather costs' (time and effort spent searching for better returns/prices) (1).
- Nominal interest rates may increase to combat inflation, increasing borrowing costs for households and firms (1).

Coherent analysis which may include the following points (up to a maximum of 6 marks):
- Reduces purchasing power of money / real value of money falls (1)
- Lowers real incomes / living standards fall if wage growth lags behind inflation (1)

Government spending on infrastructure (such as roads, ports, railways, and telecommunications) boosts economic growth through both short-run and long-run channels:

1. **Short-run Demand-side Effects:**
- Government expenditure is a direct component of aggregate demand (\(AD = C + I + G + (X - M)\)) (1).
- Infrastructure projects create direct employment in construction and engineering (1), which increases household incomes, leading to higher consumer expenditure (1) and generating multiplier effects throughout the economy (1).

2. **Long-run Supply-side Effects:**
- Improved transport networks and digital infrastructure reduce operational and distribution costs for businesses (1).
- Efficient infrastructure improves the mobility of workers and raw materials (1), increasing total factor productivity and efficiency (1).
- Modernised infrastructure makes the country more attractive to domestic and foreign direct investment (FDI) (1).
- These factors shift the country's aggregate supply / production possibility curve (PPC) outward, raising the potential productive capacity and long-term real GDP (1).

Coherent analysis which may include the following points (up to a maximum of 6 marks):
- Government spending is a component of aggregate demand / increases AD (1)
- Creates jobs / reduces unemployment in construction and related industries (1)
- Higher employment raises household disposable income and consumer spending (1)
- Triggers a positive multiplier effect (1)
- Improves transport networks / logistics / communication links (1)
- Reduces production and transportation costs for businesses / increases efficiency (1)
- Increases labour mobility / access to markets (1)
- Attracts foreign direct investment (FDI) / encourages domestic private investment (1)
- Increases the productive potential / shifts PPC outwards / increases aggregate supply (1)
- Leads to higher real output / real GDP (1)

A depreciation in the external value of a country's currency can reduce a current account deficit through the following mechanism:

1. **Impact on Relative Prices:**
- A weaker currency means foreign buyers need less of their own currency to purchase domestic goods, making exports cheaper in foreign currency terms (1).
- Conversely, domestic residents must pay more in domestic currency to buy foreign currencies, making imported goods and services more expensive (1).

2. **Changes in Quantities Demanded:**
- Cheaper export prices cause the volume of exports demanded by foreign buyers to rise (1).
- Higher import prices cause domestic consumers and firms to switch to locally produced substitutes, causing the volume of imports demanded to fall (1).

3. **Impact on Trade and Current Account Balance:**
- If demand for exports and imports is price elastic (1), total export revenue will increase (1) and total expenditure on imports will fall (1).
- As export revenue rises relative to import spending, the net trade balance (goods and services) improves (1), which directly reduces the deficit on the current account of the balance of payments (1).

Coherent analysis which may include the following points (up to a maximum of 6 marks):
- Depreciation lowers the foreign currency price of exports (1)
- Makes exports more price competitive internationally (1)
- Increases the volume / quantity demanded of exports (1)
- Depreciation raises the domestic currency price of imports (1)
- Makes imports more expensive / less attractive to domestic consumers (1)
- Encourages expenditure switching towards domestic alternatives / reduces quantity demanded of imports (1)
- If demand is price elastic / Marshall-Lerner condition met (1)
- Total export revenue increases (1)
- Total expenditure on imports decreases (1)
- Improves net exports / balance of trade in goods and services (1)
- Reduces / eliminates the current account deficit (1)

Why it may benefit workers:
- Higher incomes for low-paid workers: Increases their purchasing power, standard of living, and ability to afford basic necessities, reducing absolute poverty.
- Increased work incentives and productivity: A higher wage can boost worker morale, reduce absenteeism, and lower staff turnover, increasing labour productivity.
- Wage differentials: Higher minimum wages may lead higher-skilled workers to negotiate wage increases to restore wage differentials, benefiting other workers indirectly.

Why it may not benefit all workers:
- Increased unemployment: Firms facing higher labour costs may reduce demand for labour, substituting capital for labour or making workers redundant. Young or unskilled workers are particularly vulnerable.
- Inflationary pressures: Higher wage costs can lead to cost-push inflation as firms increase prices to maintain profit margins, reducing real wages across the economy.
- Reduction in non-wage benefits: Employers may cut overtime pay, bonuses, health benefits, or training opportunities to offset the higher wage rate.
- Informal sector growth: Some workers may be forced into unregulated, informal jobs with poorer working conditions and no legal protection.

Conclusion:
Whether all workers benefit depends on the elasticity of demand for labour, whether productivity rises alongside wages, and the extent to which employers can absorb higher costs without reducing headcounts or raising consumer prices.

Level 3 (6–8 marks):
A reasoned, two-sided discussion examining both the benefits and the disadvantages of increasing the national minimum wage for workers. Shows clear understanding of labour market concepts (e.g. purchasing power, unemployment, productivity, cost-push inflation). An evaluative conclusion is reached.

Level 2 (3–5 marks):
Economic analysis showing why workers may benefit, why they may not, or a one-sided analysis with good depth. Lacks balance or depth on one side.

Level 1 (1–2 marks):
Simple, descriptive points identifying that wages will rise or jobs might be lost, with limited economic reasoning.

Level 0 (0 marks):
No creditable response.

Why it will reduce unemployment:
- Direct job creation: Construction of roads, ports, railways, and telecommunications requires substantial labour, directly reducing cyclical and seasonal unemployment.
- Multiplier effect: Increased government spending boosts aggregate demand (AD). Construction workers spend their incomes on goods and services, stimulating output and employment in other sectors.
- Long-run supply-side improvements: Better infrastructure lowers transport and logistics costs for firms, improving international competitiveness and attracting foreign direct investment (FDI), creating permanent long-term jobs.

Why it may not reduce unemployment:
- Structural skills mismatch: If the unemployed lack the technical or engineering skills required for modern infrastructure projects, structural unemployment will persist.
- Time lags: Major infrastructure projects take years to plan and execute, meaning unemployment may not fall in the short term.
- Crowding out effect: If financed through government borrowing, rising interest rates could reduce private sector investment and employment elsewhere.
- Capital intensity: Modern infrastructure often uses advanced machinery and technology rather than large amounts of labour, limiting the number of new jobs created.

Conclusion:
Government infrastructure spending is likely to reduce unemployment if supported by training programmes to upskill workers and if the economy has spare capacity, avoiding excessive demand-pull inflation and private sector crowding out.

Level 3 (6–8 marks):
A balanced, two-sided discussion exploring how infrastructure expenditure influences employment via aggregate demand, supply-side capacity, and the multiplier, while considering limitations such as skills mismatches, time lags, or crowding out. An evaluative conclusion is provided.

Why consumers may benefit:
- Economies of scale: A monopoly operating on a large scale can achieve significant internal economies of scale (e.g. purchasing, technical), leading to lower average total costs that may be passed on as lower consumer prices.
- Dynamic efficiency and R&D: Monopolies earn supernormal profits in the long run, which can be reinvested into research and development, resulting in new innovations, superior technology, and higher-quality products.
- Natural monopoly efficiency: In network industries (e.g. water or electricity distribution), a single provider avoids wasteful duplication of costly infrastructure, ensuring lower supply costs for households.

Why consumers may not benefit:
- Higher prices and restricted output: Due to high barriers to entry and lack of competition, monopolies can set high prices and reduce supply to maximise profits.
- Lack of consumer choice: Consumers must buy from the single supplier with few or no substitutes available, reducing consumer sovereignty.
- X-inefficiency: Without competition, monopolies may become complacent, allowing costs to rise and offering poor customer service or sub-standard product quality.
- Price discrimination: Monopolies may charge different prices to different consumer groups based on PED, extracting consumer surplus.

Conclusion:
Whether consumers benefit depends heavily on the presence of effective government regulation (e.g. price caps and quality standards), the contestability of the market, and whether the monopoly passes cost savings from economies of scale on to consumers.

Level 3 (6–8 marks):
A reasoned two-sided discussion evaluating the impact of a monopoly on consumers. Accurately applies concepts such as economies of scale, R&D/innovation, price-setting power, choice, and inefficiencies. Supported by a reasoned judgment.

Level 2 (3–5 marks):
Clear economic analysis of advantages or disadvantages to consumers, but lacking full balance or analytical depth on one side.

Level 1 (1–2 marks):

Why the country may benefit from tariffs:
- Protection of domestic industries and jobs: Tariffs raise the domestic price of imports, making domestic goods relatively cheaper, shifting demand to domestic producers, and preserving local employment.
- Infant industry argument: Emerging domestic industries gain protection from mature foreign competitors until they can achieve economies of scale and become internationally competitive.
- Current account improvement: Reduced import expenditure can help narrow or eliminate a deficit on the trade in goods balance.
- Government revenue: Tariffs generate tax revenue for the government, which can be spent on public services, infrastructure, or education.
- Protection against dumping: Tariffs counteract foreign firms selling below cost to eliminate local competitors.

Why the country may not benefit:
- Retaliation and trade wars: Trading partners are likely to retaliate with tariffs on the country's exports, damaging export industries and causing net job losses.
- Higher prices for consumers: Tariffs directly increase the price of imported finished goods and imported raw materials/components, reducing consumer real incomes and increasing domestic production costs (cost-push inflation).
- Loss of economic efficiency: Tariffs protect inefficient domestic firms from global competition, reducing productivity and innovation.
- Reduced consumer choice: Consumers have access to a smaller variety and potentially lower quality of goods.

Conclusion:
Imposing a blanket tariff on all imports is unlikely to benefit the country overall due to retaliatory tariffs and widespread cost-push inflation. Targeted tariffs on specific dumping or infant industries are generally far more beneficial than universal trade barriers.

Level 3 (6–8 marks):
A reasoned two-sided discussion analysing the economic effects of tariffs on domestic producers, consumers, government revenue, the current account, and risks of retaliation. Contains a well-reasoned evaluative conclusion.

Level 2 (3–5 marks):
