2024 Cambridge IGCSE Economics (0455) 模拟试题及答案详解

The economic problem of scarcity arises because resources are finite, while human wants are unlimited. Therefore, any economic agent, including governments, must make choices on how to allocate their limited budget.

1 mark for the correct option A. 0 marks for incorrect options.

Opportunity cost is the value of the next best alternative foregone. If the farmer chooses strawberries (profit of $15,000), the next best alternative crop is tomatoes, which would have yielded a profit of $12,000. Therefore, the opportunity cost is $12,000.

1 mark for correct calculation of opportunity cost ($12,000). 0 marks for other options.

Public goods are non-excludable and non-rival, meaning it is impossible to prevent people from using them once provided. Consequently, they suffer from the free-rider problem and cannot be efficiently provided by the price mechanism. Merit goods are excludable and rival, so they can be provided via the market, though they are typically under-consumed.

1 mark for identifying the correct distinguishing characteristic. 0 marks for incorrect options.

The percentage change in price is (($2.40 - $2.00) / $2.00) * 100 = +20%. Since PED is -0.5, the percentage change in quantity demanded is -0.5 * 20% = -10%. The new quantity demanded is 1,000 * (1 - 0.10) = 900 passengers. The new total revenue is 900 passengers * $2.40 = $2,160.

1 mark for correct calculation steps leading to $2,160. 0 marks for incorrect revenue values.

Variable costs change directly in proportion to the level of output. Wages paid to temporary workers per unit assembled are a variable cost because they increase as more units are produced. Rent, insurance premiums, and license fees are fixed costs because they do not change with the output level in the short run.

1 mark for selecting the option that represents a variable cost. 0 marks for fixed cost options.

Real GDP growth is calculated by adjusting nominal GDP growth for inflation. Real GDP growth approximately equals Nominal GDP growth minus the inflation rate: 5% - 3% = 2%.

1 mark for subtracting inflation from nominal growth to get 2%. 0 marks for incorrect options.

An ageing population occurs when the average age of the population increases. A falling birth rate reduces the proportion of young people, and a falling death rate increases life expectancy, allowing more people to survive into old age.

1 mark for identifying the correct combination of falling birth and death rates. 0 marks for other combinations.

Increasing welfare benefits targets lower-income households directly. Funding these benefits using a progressive income tax means high earners pay a higher percentage of their income, redistributing income from the rich to the poor and lowering inequality.

1 mark for the correct policy option. 0 marks for regressive or neutral tax policies.

A pure public good is characterized by non-excludability (it is impossible to prevent non-payers from consuming it) and non-rivalry (one person's consumption does not reduce the amount available to others). Thus, option B is correct.

Award 1 mark for the correct option B.

Opportunity cost is defined as the value of the next best alternative forgone. The farmer chose to grow potatoes (yielding $5000). The alternative options were growing wheat ($4000) and leasing the land ($3500). The next best alternative forgone is growing wheat, which yields a profit of $4000.

Award 1 mark for the correct option B.

Percentage change in quantity demanded = \(\frac{130 - 100}{100} \times 100\% = +30\%\).

Percentage change in price = \(\frac{8 - 10}{10} \times 100\% = -20\%\).

Price elasticity of demand (PED) = \(\frac{+30\%}{-20\%} = -1.5\).

Award 1 mark for the correct option C.

The tax is levied directly on individual citizens, making it a direct tax. Because it is a flat amount, it represents a larger percentage of income for low-income earners than for high-income earners, making it regressive. Therefore, it is a direct and regressive tax.

Award 1 mark for the correct option B.

Total Cost (TC) = Average Total Cost (ATC) \(\times\) Output (Q) = \(\$9 \times 200 = \$1800\).

Total Variable Cost (TVC) = Total Cost (TC) - Total Fixed Cost (TFC) = \(\$1800 - \$1000 = \$800\).

Award 1 mark for the correct option A.

The introduction or expansion of state pensions for the elderly reduces parents' reliance on their children for financial support in old age. This typically leads to a decrease in the birth rate. Options A, B, and D are factors that would tend to increase or sustain a higher birth rate.

Award 1 mark for the correct option C.

Real GDP growth rate can be approximated as: Nominal GDP growth rate - Inflation rate = \(5\% - 3\% = +2\%\) (Real GDP rose).

Real GDP per head growth rate can be approximated as: Real GDP growth rate - Population growth rate = \(2\% - 4\% = -2\%\) (Real GDP per head fell).

Award 1 mark for the correct option B.

A currency depreciation makes exports cheaper for foreigners and imports more expensive for domestic buyers. Since demand is price-elastic, this will increase export revenue and decrease import spending, improving the balance of trade in goods. However, the higher cost of imported raw materials and finished goods will increase production costs, leading to imported inflation and an increase in the domestic inflation rate.

Award 1 mark for the correct option D.

Opportunity cost is defined as the cost of the next best alternative foregone. The alternatives to building the shopping mall are:
1. The residential housing complex, valued at $12 million.
2. The public nature park, valued at $8 million ($5 million + $3 million).

The next best alternative is the residential housing complex, which has a value of $12 million. Therefore, the opportunity cost is $12 million.

1 mark for the correct answer B.
Incorrect options explanation:
- A: $5 million represents only the private return of the park (not the next best option).
- C: $17 million erroneously adds the values of other alternatives instead of selecting the next best single option.
- D: $27 million adds all alternative values together.

An external cost (negative externality) is a cost imposed on a third party who is not involved in the economic transaction (production/consumption). The municipal water authority is a third party, and the purification costs they incur represent an external cost of the plant's production.

1 mark for the correct answer C.
Incorrect options explanation:
- A: This is a private cost to the firm.
- B: This is a private cost to the firm.
- D: This is a private cost/impact on the firm itself.

1. Find Total Fixed Cost (TFC). At zero output, variable costs are zero, meaning Total Cost is equal to Fixed Cost. Therefore, $\text{TFC} = $50$.
2. Calculate Average Fixed Cost (AFC) at 20 units of output:
$$\text{AFC} = \frac{\text{TFC}}{\text{Output}} = \frac{\$50}{20} = \$2.50$$

1 mark for the correct answer A.
Incorrect options explanation:
- B: This is the Average Variable Cost at 20 units ($110 / 20 = $5.50).
- C: This is the Average Total Cost at 20 units ($160 / 20 = $8.00).
- D: This is the Total Fixed Cost, not the average.

A declining birth rate means fewer young people are born, while a rising life expectancy means older individuals live longer. Together, these trends lead to an aging population, which increases the proportion of dependents (the elderly) relative to the working-age population, thus raising the dependency ratio.

1 mark for the correct answer B.
Incorrect options explanation:
- A: The average age of the workforce will increase, not decrease.
- C: Government spending on healthcare and pensions is highly likely to increase.
- D: The total population may not continuously increase; it could eventualy decline if the birth rate falls below the replacement level.

1. Change in Real GDP $\approx$ % change in nominal GDP - % inflation rate = $6\% - 8\% = -2\%$. Therefore, real GDP has decreased.
2. The rate of inflation is positive ($+8\%$), which means the general price level has increased.

1 mark for the correct answer C.
Incorrect options explanation:
- A: Real GDP has decreased, not increased, because inflation exceeded nominal growth.
- B: Price level has increased because inflation is positive; Real GDP decreased.
- D: Price level increased due to inflation; only Real GDP decreased.

- Lowering interest rates reduces the reward for saving, causing consumer saving to decrease.
- Lowering interest rates reduces the cost of borrowing for firms, causing business investment to increase.
- Increased spending stimulates aggregate demand, leading to higher output and lower unemployment.

1 mark for the correct answer A.
Incorrect options explanation:
- B: Business investment will increase, not decrease.
- C: Saving will decrease, not increase.
- D: Saving will decrease, business investment will increase, and unemployment will decrease.

1. % change in Price = $\frac{12 - 10}{10} \times 100 = 20\%$
2. % change in Quantity Demanded = $\frac{450 - 500}{500} \times 100 = -10\%$
3. $\text{PED} = \frac{-10\%}{20\%} = -0.5$ (inelastic).
4. Original Total Revenue = $10 \times 500 = $5,000$.
5. New Total Revenue = $12 \times 450 = $5,400$.
6. Total revenue increases because demand is price inelastic.

1 mark for the correct answer B.
Incorrect options explanation:
- A: The calculation of PED is incorrect (-0.5, not -2.0) and total revenue actually increases.
- C: The PED is correct but total revenue increases, not decreases.
- D: The calculation of PED is incorrect (-0.5, not -1.1).

- Progressive taxes (such as higher marginal income tax rates for high earners) redistribute wealth and reduce income inequality.
- High indirect taxes on demerit goods (like cigarettes) increase their price, thereby reducing consumption.

1 mark for the correct answer B.
Incorrect options explanation:
- A: Reducing VAT on luxury goods benefits high-income earners, worsening inequality.
- C: A uniform subsidy does not target income inequality directly and does not reduce demerit goods.
- D: Funding pensions with a regressive tax would worsen inequality because low-income earners pay a higher proportion of their income in sales taxes.

A coastal flood barrier is a public good because it is non-rival (one person's benefit does not reduce another's) and non-excludable (it is impossible to prevent anyone in the city from benefiting from the flood protection).

1 mark for B. Non-excludability and non-rivalry define a public good.

At 20 units of output:
Total Cost = Total Fixed Cost + Total Variable Cost = $100 + $80 = $180.
Average Total Cost (ATC) = Total Cost / Output = $180 / 20 = $9.

1 mark for C. Correct calculation: (100 + 80) / 20 = 9.

First, calculate natural population increase:
Births - Deaths = (15 - 10) = 5 per 1000.
Natural increase = 10,000,000 * (5 / 1000) = 50,000.
Next, account for net migration:
Net migration is -50,000 (net outward migration).
Overall change = +50,000 - 50,000 = 0.
Therefore, the total population remains 10,000,000.

1 mark for B. Natural increase (+50,000) cancels out net outward migration (-50,000).

Real GDP growth rate can be approximated as: Nominal GDP growth rate - Inflation rate.
- Country A: 8% - 5% = 3%
- Country B: 6% - 1% = 5%
- Country C: 4% - (-2%) = 6% (deflation increases real GDP growth relative to nominal)
- Country D: 10% - 9% = 1%
Country C has the highest real GDP growth at 6%.

1 mark for C. Correct calculation of real GDP growth accounting for negative inflation (deflation).

To reduce a budget deficit, a government needs to increase its revenue and/or decrease its expenditure. Increasing direct taxes increases government tax revenue, while decreasing spending on welfare benefits reduces government expenditure. This combination is the most direct way to reduce a deficit.

1 mark for C. Increasing revenue via taxation combined with cutting spending reduces the deficit.

Opportunity cost is defined as the next best alternative foregone. Since the student's second-choice preference is the textbook, this is the next best alternative given up when they choose to buy their first-choice option (the concert ticket).

1 mark for B. The textbook is the second preference (the next best alternative).

**1 (a)**
Calculation: \( (\$35\text{bn} / \$115\text{bn}) \times 100 \approx 30.43\% \). Accept rounded values such as 30.4% or 30%. Accept without the percentage sign.

**1 (b)**
Any two examples of external costs from the source material:
* Air pollution
* Congestion
* Water depletion (in Lake Naivasha)
* Chemical runoff/killing of fish/destruction of ecosystems
* Waterborne illness/diseases

**1 (c)**
* Real GDP per capita represents average real income per person (1).
* Higher real GDP per capita means individuals have greater purchasing power/can buy more goods, services, and basic necessities, which indicates a higher material standard of living (1).

**1 (d)**
* **Impact on Health/Life Expectancy:** Chemical runoff/pollution leads to waterborne illnesses (1) which reduces the average health of the population and lowers life expectancy (a key component of the HDI) (1).
* **Impact on GNI/Income:** Water pollution kills fish (1) which directly lowers the incomes and livelihoods of local fishing communities, reducing Kenya's GNI per capita (a key component of the HDI) (1).

**1 (e)**
* Axes correctly labelled with two different output types (e.g., Agricultural Goods and Manufacturing Goods) (1).
* An initial PPC curve drawn sloping downward to the axes (1).
* A new PPC curve drawn shifting inwards (to the left) (1).

**1 (f)**
* **Expected relationship:** There is generally a positive/direct relationship (1) where countries with a higher GDP spend more on environmental protection (1).
* **Supporting evidence:** Germany has both the highest GDP ($4260bn) and the highest environmental spending ($38.50bn) (1). Ethiopia has a lower GDP ($110bn) and very low environmental spending ($0.18bn) (1).
* **Exception:** Kenya and Ecuador (or Colombia and Ecuador) (1). Ecuador has a lower GDP ($105bn) than Kenya ($115bn) but spends more on the environment ($0.35bn compared to $0.25bn) (1).
* **Further analysis:** Higher GDP nations generate more tax revenues and can afford to allocate funds to sustainability, whereas lower-income nations must prioritise immediate needs such as poverty alleviation (1).

**1 (g)**
* **Why it might benefit:**
* Farmers move to drier areas and cultivate alternative drought-resistant crops (1), which increases diversification and overall food security (1).
* Reduces population pressure and overcrowding in areas like Naivasha (1), relieving pressure on local public resources such as schools and clinics (1).
* Allocates labor to areas where resources are under-utilized (1), raising regional output and efficiency (1).
* **Why it might not benefit:**
* It can lead to the collapse or decay of existing rural agricultural communities (1) because they are left without enough active workers (1).
* It increases economic inequality (1) between highly mobile agricultural specialists and less-mobile manual laborers who cannot relocate (1).
* Places sudden demands on infrastructure and resources in the destination areas, generating congestion/external costs (1).

**1 (h)**
* **Why it might benefit:**
* It will create thousands of job opportunities in manufacturing (1), which reduces structural unemployment (1).
* It will help redistribute economic development and diversify the economy away from Nairobi (1), reducing regional wealth disparities (1).
* Using solar energy means the zone is carbon-neutral (1), reducing environmental damage and external costs (1).
* **Why it might not benefit:**
* High financial cost of $15 billion has a significant opportunity cost (1); these funds could have been spent on rural healthcare or education (1).
* The benefits might be concentrated among wealthy multinational corporations (1) rather than helping the local poor or coastal communities (1).
* Industrial manufacturing can still cause localized noise or chemical pollution despite running on renewable solar energy (1).

**(a) Define the tertiary sector using an example.**
The tertiary sector is the segment of the economy that provides services to consumers and businesses rather than producing physical, tangible goods. Examples include banking, tourism, education, hairdressing, and healthcare.

**(b) Explain two reasons why trade union membership might decline.**
- **Structural shift in employment:** There has been a global shift from heavily unionised secondary industries (such as manufacturing and mining) to the tertiary and gig service sectors, where workers are traditionally less organised and more scattered.
- **Growth of flexible/part-time contracts:** An increasing number of workers are on temporary, part-time, or zero-hour contracts. These workers often feel less connected to a specific workplace, making them less likely to join trade unions.
- **Government legislation:** Many governments have introduced laws that restrict the power of trade unions, such as limiting the right to strike or making union registration more difficult, which reduces the perceived benefits of membership.

**(c) Analyse how supply-side policies can increase economic growth.**
Supply-side policies aim to increase the productive capacity (potential output) of an economy. They can achieve this in several ways:
- **Investment in education and training:** By improving the skills and knowledge of the workforce, labor productivity increases, allowing firms to produce more output with the same number of workers.
- **Infrastructure spending:** Improving transport networks (roads, rail) and communication technologies (broadband) reduces logistics costs and delays for firms, enhancing overall economic efficiency.
- **Subsidies and tax incentives for R&D:** Offering tax breaks or grants to companies that innovate encourages technological progress, leading to the creation of more efficient production methods and new products.
- **Deregulation and privatization:** Reducing bureaucratic red tape and introducing competition into previously state-run industries can lower costs, encourage enterprise, and increase aggregate supply.

**(d) Discuss whether or not the growth of the gig economy benefits workers.**
**Why it might benefit workers:**
- **Flexibility and autonomy:** Workers can choose when, where, and how much they work, making it easier to balance employment with other commitments such as studies, family care, or leisure.
- **Lower barriers to entry:** Gig work often requires minimal formal qualifications to start (e.g., delivery riding or ride-sharing), providing quick income opportunities for unemployed or low-skilled individuals.
- **Supplementary income:** It allows workers with full-time jobs to earn extra income in their spare time, improving their living standards.

**Why it might not benefit workers:**
- **Lack of job security and income volatility:** Gig workers are typically classified as self-employed independent contractors, meaning they can have their hours cut or accounts deactivated with no notice, leading to unpredictable earnings.
- **Absence of employment benefits:** They are generally not entitled to statutory benefits such as paid sick leave, annual holiday pay, pension contributions, or health insurance, shifting all financial risks onto the individual.
- **Low wages due to high competition:** As barriers to entry are low, an oversupply of labor can drive down the piece-rates or hourly returns, making it difficult for workers to earn a basic living wage.

**(a) Define the tertiary sector using an example.**
- **1 mark** for defining the tertiary sector as the service-producing sector / intangible output.
- **1 mark** for a valid example (e.g., insurance, retail, hospitality).

**(b) Explain two reasons why trade union membership might decline.**
- **1 mark** for each of the two reasons identified (up to 2 marks).
- **1 mark** for explanation of how each reason leads to a decline in union membership (up to 2 marks).

**(c) Analyse how supply-side policies can increase economic growth.**
- **1 to 2 marks** for identifying specific supply-side policies (e.g., education spending, infrastructure, deregulation).
- **1 to 4 marks** for explaining the transmission mechanism (e.g., education increases productivity, which shifts the PPC/LRAS to the right, lowering average costs and increasing potential GDP).

**(d) Discuss whether or not the growth of the gig economy benefits workers.**
- **Up to 4 marks** for logical arguments supporting why it benefits workers (flexibility, autonomy, extra income sources).
- **Up to 4 marks** for logical arguments supporting why it does not benefit workers (lack of sick pay/holiday pay, income insecurity, low average earnings due to intense competition).

**(a) Define negative externality.**
A negative externality is a harmful side effect or external cost imposed on a third party as a result of an economic transaction (production or consumption) that is not reflected in the market price.

**(b) Explain two advantages of a horizontal merger.**
- **Economies of scale:** Merging two firms at the same stage of production allows them to operate on a larger scale, reducing average costs through bulk purchasing, marketing economies, or administrative consolidation.
- **Increased market share and power:** Combining operations eliminates a direct competitor, giving the merged firm greater control over pricing and market supply.
- **Rationalisation of resources:** The merged firm can eliminate duplicate departments, such as payroll or regional headquarters, saving significant operating costs.

**(c) Analyse why the demand for international tourism might be price elastic.**
- **High proportion of income:** Foreign travel and holidays are expensive luxury items that represent a substantial portion of a household's annual budget. Therefore, a small percentage change in price has a major impact on whether consumers can afford the trip.
- **Large number of close substitutes:** Tourists can easily switch between different destinations or choose domestic holidays if international travel prices rise.
- **Non-essential nature of the product:** Unlike food or healthcare, international tourism is not a necessity. Consumers can easily delay, shorten, or cancel holidays if prices increase, making demand highly responsive to price changes.

**(d) Discuss whether or not a tax on tourist activities will benefit the economy.**
**Why it might benefit the economy:**
- **Internalises the negative externality:** A tax on polluting tourist activities increases the private cost of consumption, aligning it with the social cost. This disincentivises harmful behaviors and reduces waste and environmental damage.
- **Raises government revenue:** The tax proceeds can be earmarked for public spending, such as investing in clean waste-management systems, preserving national parks, or improving local infrastructure.
- **Promotes sustainable, high-value tourism:** Preserving the environment maintains the long-term attractiveness of the island, ensuring sustainable tourism revenues in the future.

**Why it might not benefit the economy:**
- **Reduces international competitiveness:** The tax increases the cost of visiting the island. Since tourism demand is highly price elastic, tourists may choose cheaper alternative destinations, causing a sharp drop in visitor numbers.
- **Harms domestic businesses and employment:** A fall in tourist numbers will negatively affect hotels, restaurants, and local transport providers, leading to business closures and higher unemployment.
- **Administrative costs:** Implementing and policing the tax system takes up government resources that could have been used elsewhere (opportunity cost).

**(a) Define negative externality.**
- **2 marks** for a complete definition (harmful third-party effect where social cost exceeds private cost).
- **1 mark** for a partial definition (e.g., external cost / pollution).

**(b) Explain two advantages of a horizontal merger.**
- **1 mark** for each of the two advantages identified (up to 2 marks).
- **1 mark** for the explanation of how each advantage benefits the firm (up to 2 marks).

**(c) Analyse why the demand for international tourism might be price elastic.**
- **1 to 2 marks** for identifying factors influencing PED (e.g., luxury, substitutes, percentage of income).
- **1 to 4 marks** for explaining how these factors make demand highly responsive to price changes.

**(d) Discuss whether or not a tax on tourist activities will benefit the economy.**
- **Up to 4 marks** for logical arguments supporting why the tax is beneficial (environmental cleanup, revenue collection, correcting market failure).
- **Up to 4 marks** for logical arguments why it might not be beneficial (loss of tourism competitiveness, job losses in hospitality, implementation costs).

**(a) Define absolute poverty.**
Absolute poverty is a state where a person or family lives below a minimum income threshold required to afford the basic necessities of life, including food, shelter, clean water, clothing, and basic healthcare.

**(b) Explain two reasons for a high birth rate in a developing country.**
- **High infant mortality rate:** In many developing countries, healthcare standards are low. Families may choose to have more children to increase the probability that some will survive into adulthood.
- **Lack of sex education and family planning resources:** Limited availability, affordability, or education about modern contraceptives leads to higher rates of unplanned pregnancies.
- **Children as economic assets:** In agrarian or informal economies, children can work from a young age to support the family income or provide essential care for parents in their old age due to the absence of state pension schemes.

**(c) Analyse how expansionary fiscal policy can reduce absolute poverty.**
Expansionary fiscal policy involves increasing government spending and/or reducing taxes to stimulate economic activity. This can reduce absolute poverty through several channels:
- **Increased spending on public infrastructure:** Capital projects such as building roads, schools, and hospitals create immediate employment opportunities for low-skilled workers, raising their household incomes.
- **Higher transfer payments:** Direct financial support, such as unemployment benefits, disability allowances, or food subsidies, directly increases the disposable income of the poorest individuals, allowing them to purchase basic food and shelter.
- **Increased spending on education and healthcare:** Free public services improve the human capital of poor households, giving younger generations the skills needed to secure higher-paying jobs in the future, breaking the cycle of poverty.
- **Cuts in direct or indirect taxes:** Reducing indirect taxes (like sales tax or VAT) on basic foodstuffs and essentials increases the real purchasing power of low-income families.

**(d) Discuss whether or not population growth is always a disadvantage for a developing economy.**
**Why it is a disadvantage:**
- **Strains public infrastructure:** Rapid population growth outpaces the construction of schools, hospitals, housing, and sanitation systems, leading to overcrowding, pollution, and lower-quality services.
- **Reduces GDP per head:** If the rate of population growth is higher than the rate of economic growth, the average income per person will fall, reducing overall living standards.
- **High youth dependency ratio:** A high birth rate means a large percentage of the population is under 16, requiring substantial state spending on consumption (education/health) without contributing to tax revenue or production.

**Why it might not be a disadvantage (benefits):**
- **Future labor supply expansion:** A growing population ensures a steady supply of young, dynamic workers in the future, preventing labor shortages and keeping labor costs competitive to attract foreign direct investment (FDI).
- **Increases domestic demand:** A larger population creates a larger market for domestic firms, encouraging investment, innovation, and business expansion, which drives long-term economic growth.
- **Opportunity for economies of scale:** Larger domestic demand allows firms to expand production and benefit from lower average costs, making exports more competitive globally.

**(a) Define absolute poverty.**
- **2 marks** for a clear definition mentioning a lack of income to afford basic survival necessities (food, shelter, water).
- **1 mark** for stating it is 'extreme poverty' or 'living on very little money' without referencing basic survival needs.

**(b) Explain two reasons for a high birth rate in a developing country.**
- **1 mark** for each of the two reasons identified (up to 2 marks).
- **1 mark** for explaining how each reason results in a higher birth rate (up to 2 marks).

**(c) Analyse how expansionary fiscal policy can reduce absolute poverty.**
- **1 to 2 marks** for identifying fiscal measures (e.g., transfer payments, infrastructure spending, tax cuts on essentials).
- **1 to 4 marks** for a coherent analysis explaining how these measures increase the disposable income or productive capacity of the poorest households.

**(d) Discuss whether or not population growth is always a disadvantage for a developing economy.**
- **Up to 4 marks** for logical arguments supporting why it is a disadvantage (pressure on resources, high dependency ratio, falling GDP per capita).
- **Up to 4 marks** for logical arguments explaining why it is not always a disadvantage (larger future workforce, expanding market demand, economies of scale).
