Economics 0455 | Paper 1 Mock 01 | Multiple Choice

The correct answer is Higher growth is associated with increased environmental damage.

The data shows a clear positive relationship between real GDP growth and CO2 emissions. As growth increased from 2.5% to 4.0% to 5.5% over the three years, CO2 emissions rose from 180 to 210 to 250 million tonnes. This illustrates the trade-off between economic growth and environmental quality: faster growth tends to come with greater environmental damage in the form of higher emissions.

The option about growth reducing the need for government intervention is not supported by the data. The option about faster growth leading to lower unemployment may be true but is not illustrated by this data, which focuses on emissions. The option that growth always leads to improved living standards ignores the environmental costs visible in the table.

The correct answer is Country B has a higher level of absolute poverty than Country A.

The data shows that 38% of Country B's population lives on less than $2.15 per day, compared to just 0.1% in Country A. Living below $2.15 per day is an internationally recognised measure of absolute poverty. Country B also has a much lower GDP per capita ($3,500 vs $45,000), lower life expectancy (54 vs 81 years), and a lower adult literacy rate (62% vs 99%), all of which are consistent with higher poverty.

The data does not provide information about income inequality within each country, so we cannot conclude which has higher inequality. There is no data on defence spending or economic growth rates, so those claims are not supported.

An inflation target gives the central bank a clear benchmark for price stability. When inflation exceeds the target, the bank must act to bring it back down.

The correct answer is raise interest rates to reduce aggregate demand. Higher interest rates increase the cost of borrowing and make saving more attractive, which reduces consumer spending and business investment. The resulting fall in aggregate demand eases the upward pressure on prices, helping to bring inflation back toward the 2% target.

Lowering interest rates to encourage spending would increase aggregate demand and push inflation further above target. Printing more money would increase the money supply and fuel further inflation rather than reducing it. Increasing government spending is a fiscal policy measure, not a monetary policy action, and would also add to aggregate demand.

The correct answer is an increase in the country's potential economic growth.

The discovery of large natural gas deposits expands the country's natural resource base, which is one of the four factors of production (land, labour, capital, enterprise). A greater quantity of resources means the economy's productive capacity increases, which is represented by an outward shift of the PPC. This constitutes potential economic growth, as the economy can now produce more goods and services than before.

A decrease in productive capacity and an inward shift of the PPC are the opposite of what a resource discovery causes. A fall in real GDP would not be expected when a country gains access to valuable new resources that can be extracted and exported.

The correct answer is $10,000.

The credit multiplier determines the maximum total deposits the banking system can create from an initial deposit. It is calculated as:

\[ \text{Credit multiplier} = \frac{1}{\text{Reserve ratio}} = \frac{1}{0.10} = 10 \]

Maximum total deposits = Initial deposit \(\times\) Credit multiplier = $1,000 \(\times\) 10 = $10,000.

This $10,000 figure represents the total deposits in the banking system, including the original $1,000. The process works because the bank lends out $900 (keeping $100 in reserve), which is deposited elsewhere and re-lent, and so on until the total reaches $10,000. The figure of $9,000 would represent only the new loans created, not the total deposits. $1,000 is only the initial deposit, and $100,000 would require a 1% reserve ratio.

The correct answer is help lower-income workers keep more of their earnings.

A tax-free allowance (also called a personal allowance) means the first portion of a worker's income is not subject to tax. This benefits all workers, but it has the greatest proportional impact on lower-income earners because the untaxed amount represents a larger share of their total income. For example, a $10,000 tax-free allowance saves the same absolute amount for everyone, but it shields a much larger fraction of a $15,000 salary than a $100,000 salary. The policy therefore makes the overall tax system more progressive and helps reduce the tax burden on the lowest earners.

Increasing national debt, reducing growth, or discouraging workers from seeking higher-paid jobs are not objectives of a tax-free allowance and do not logically follow from its introduction.

The correct answer is there is often a time lag between implementing the policy and its effects being felt.

Fiscal policy changes require time at multiple stages. There is a recognition lag (identifying the problem), a decision lag (debating and passing legislation), and an implementation lag (putting the policy into practice). Even after implementation, it takes further time for the spending or tax changes to work through the economy via the multiplier process. These time lags mean fiscal policy cannot deliver instant results and may even be poorly timed if economic conditions change before the effects materialise.

Fiscal policy can affect both the demand side and the supply side of the economy, so the claim that it only affects supply is wrong. It can certainly influence employment (through aggregate demand) and it does affect aggregate demand by definition.

The correct answer is that both workers pay the same percentage of their income in tax.

A proportional tax (also called a flat-rate tax) charges the same percentage of income regardless of how much a person earns.

• Worker A: $6,000 / $30,000 = 20%
• Worker B: $12,000 / $60,000 = 20%

Both workers pay exactly 20% of their income in tax, confirming the tax is proportional.

They do not pay the same amount in tax (Worker B pays $12,000 while Worker A pays $6,000), so that option is incorrect. A progressive tax would require the higher earner to pay a higher percentage. A regressive tax would mean the lower earner pays a higher percentage. Neither is the case here.

The correct answer is the affordable housing that cannot now be built. Opportunity cost is the value of the next best alternative forgone. By choosing to build the stadium, the government uses resources that could have gone toward affordable housing. The housing that cannot be built represents the true opportunity cost.

The construction cost of the stadium is a direct monetary cost, not an opportunity cost. The revenue from ticket sales describes the benefit of the chosen option. The cost of land is a factor of production cost, not the forgone alternative use of the budget.

Internal migration refers to the movement of people within a country, for example from rural to urban areas or from one region to another. International migration involves crossing national borders. Net emigration refers to more people leaving a country than entering it. Forced immigration involves people being compelled to move to another country, usually due to conflict or persecution.

The correct answer is Expansionary.

Expansionary fiscal policy involves increasing government spending, reducing taxation, or both, in order to stimulate aggregate demand and boost economic activity. During a recession, output and employment fall. By spending more on infrastructure such as roads and bridges, the government directly injects money into the economy, creating jobs and increasing demand for materials and services.

Supply-side policy focuses on improving the productive capacity of the economy (for example, through education or deregulation), not on short-term demand stimulus. Monetary policy involves changes to interest rates or the money supply by the central bank, not government spending decisions. Contractionary fiscal policy involves reducing spending or increasing taxes to slow down an overheating economy, which is the opposite of what is described here.

The correct answer is the profit motive influencing business decisions.

In both market economies and mixed economies, private firms exist and are driven by the desire to earn profit. The profit motive encourages firms to produce goods and services that consumers want, to innovate, and to keep costs low. In a planned economy, the state owns the means of production and decisions are made by central planners rather than by profit-seeking firms, so the profit motive is weak or absent.

State ownership of all major industries is a feature of planned economies, not market or mixed ones. Central government allocation of all resources also characterises planned economies. A complete absence of private enterprise would mean no profit motive at all, which contradicts both market and mixed systems.

The correct answer is imported inflation because the cost of foreign goods rises.

When a country's currency depreciates (falls in value on the foreign exchange market), it takes more domestic currency to buy one unit of foreign currency. This has direct consequences for import prices:

• Imported goods become more expensive in domestic currency terms. For example, if the currency falls by 20%, an import that cost $100 now costs the equivalent of $120 in domestic currency.
• Higher import prices feed through to consumer prices (imported consumer goods) and production costs (imported raw materials and components).

This type of inflation is called imported inflation because the price increases originate from changes in the exchange rate affecting import costs.

Exports actually become cheaper in foreign currency terms (not more expensive). Production costs for domestic firms that use imported inputs will rise, not fall. The general price level is pushed upward, not downward.

Increasing income tax reduces consumers' disposable income, lowering consumption and aggregate demand, which helps reduce demand-pull inflation. Raising government expenditure would increase AD and worsen inflation. Reducing interest rates is a monetary policy tool, not fiscal. Lowering tariffs is a trade policy that might reduce costs slightly but is not a core fiscal measure to control inflation.

The correct answer is the total quantity of land available is fixed and cannot be increased. The supply of land (in the economic sense of natural resources and physical territory) is fixed by nature. No matter how high the price rises, the total area of land on Earth cannot be expanded. This means the supply curve for land is a vertical line, indicating perfectly inelastic supply (price elasticity of supply equals zero).

While it is true that the price of land changes with demand, this describes movement along the demand curve, not the reason for the vertical supply curve. The fact that land can be used for many different purposes relates to occupational mobility, not supply elasticity. Variation in demand between urban and rural areas affects relative prices but does not explain why total supply is fixed.

The correct answer is both trade creation and trade diversion.

Trade creation occurs when the formation of a trading bloc leads to an increase in total trade. Here, total trade rose from $350 billion to $450 billion, an increase of $100 billion, confirming trade creation has taken place.

Trade diversion occurs when trade is redirected from more efficient non-member producers to less efficient member producers because of preferential access within the bloc. Trade with non-members fell from $200 billion to $170 billion, a decline of $30 billion, while intra-bloc trade nearly doubled from $150 billion to $280 billion. This shift away from non-members and towards members is evidence of trade diversion.

Since the data shows both an increase in total trade and a shift away from non-members, the correct conclusion is that both effects are present. It is not trade creation only (non-member trade fell) or trade diversion only (total trade increased).

Common resources are rivalrous but non-excludable. Without property rights or regulation, individuals have no incentive to limit their use because the benefits of use are private while the costs of degradation are shared. This leads to the tragedy of the commons, where the resource is overused and depleted.

The correct answer is it seeks to generate revenue to fund a social cause rather than to earn private profit.

A charity shop is a type of social enterprise. It operates commercially by selling goods, but its primary objective is to raise funds for a charitable purpose (in this case, medical research) rather than to distribute profit to private owners or shareholders.

The claim that the shop has no costs is incorrect; even with donated goods, the shop faces costs such as rent, utilities, and staff wages. The option about maximising profits for shareholders misidentifies the organisation as a for-profit company. The suggestion that it competes directly with luxury fashion brands is inaccurate, as charity shops typically sell second-hand goods at low prices in a different market segment.

Crowding out occurs when increased government borrowing raises interest rates in the loanable funds market, making it more expensive for private firms to borrow and invest. This reduces private sector investment, partially offsetting the expansionary effect of government spending.

The correct answer is beyond the revenue-maximising tax rate.

The Laffer curve shows that as the tax rate increases from zero, total tax revenue initially rises. However, beyond a certain point (the revenue-maximising rate), further increases in the tax rate cause total revenue to fall. This happens because very high tax rates discourage work, investment, and enterprise, shrinking the tax base by more than the higher rate gains.

The specific percentage at which revenue is maximised varies by economy and is not fixed at 25% or 50%. At a 0% tax rate, no revenue is collected at all, so a further increase from zero would raise revenue, not reduce it.

The correct answer is have more children to ensure that some survive to adulthood.

In countries with high infant mortality, many children die before reaching adulthood due to disease, malnutrition, and inadequate healthcare. Families respond by having more children as a form of insurance, increasing the likelihood that enough children survive to support parents in old age and contribute to the household. This creates a link between high infant mortality and high birth rates. As healthcare improves and infant mortality falls, families gradually have fewer children because more of them survive, contributing to the demographic transition.

The other options describe the opposite relationship or are not the primary explanation. Families preferring fewer children when healthcare is available describes what happens when infant mortality falls. Families are typically well aware of their children. Government payments may exist in some countries but are not the main explanation for this pattern.

The correct answer is that it may be difficult to accurately estimate the external cost and set the correct tax rate.

When a government uses a Pigouvian tax to correct a negative externality, it should set the tax equal to the external cost per unit at the socially optimal output level. However, measuring external costs precisely is extremely difficult. Pollution damage, health impacts, and environmental degradation are hard to quantify in monetary terms. If the tax is set too low, the externality is only partially corrected; if set too high, output falls below the efficient level. This information problem is a genuine limitation of taxation as a policy tool.

Taxes rarely eliminate an externality completely; they aim to reduce it to the socially optimal level. Taxes do raise government revenue, which is often cited as an advantage. Consumers typically reduce but do not entirely avoid taxed products, especially for goods with inelastic demand.

The correct answer is a purchasing economy of scale.

A purchasing economy of scale arises when a large firm can buy inputs in bulk and use its bargaining power to negotiate lower prices from suppliers. A large supermarket chain places far bigger orders than a small independent shop, giving it leverage to secure discounts that reduce its average cost per unit.

A diseconomy of scale would raise costs, not lower them. An external economy of scale benefits all firms in an industry from industry-wide growth, not from one firm's own buying power. A technical economy of scale relates to the use of specialised machinery and production techniques, not purchasing discounts.

The correct answer is Bread.

To find the largest percentage price increase, calculate the percentage change for each item:

• Bread: \(\frac{2.50 - 2.00}{2.00} \times 100 = 25\%\)
• Milk: \(\frac{1.80 - 1.50}{1.50} \times 100 = 20\%\)
• Rice: \(\frac{3.30 - 3.00}{3.00} \times 100 = 10\%\)

Bread has the largest percentage price increase at 25%, compared to 20% for Milk and 10% for Rice.

Note that the absolute price increase for Bread ($0.50) is larger than Milk ($0.30) and Rice ($0.30), but the percentage increase is the relevant measure because it accounts for the different starting prices. The items clearly did not increase by the same percentage.

The correct answer is when total revenue equals total cost.

The break-even point is the level of output at which a firm's total revenue exactly equals its total cost, meaning the firm makes neither a profit nor a loss. On a TR/TC diagram, this is the point where the two curves intersect.

When total revenue exceeds total cost by the greatest amount, the firm is at the point of maximum profit, not break-even. The lowest point on the average cost curve identifies the most efficient output level, not break-even. The point where marginal cost begins to rise relates to diminishing returns, not break-even.
