The correct answer is the currency will appreciate because foreign buyers need to purchase the domestic currency.

Under a floating exchange rate, the value of the currency is determined by supply and demand in the foreign exchange market.

When demand for a country's exports increases significantly:

• Foreign buyers need to purchase the domestic currency to pay for the exports.
• This increases demand for the domestic currency on the foreign exchange market.
• Higher demand for the currency causes it to appreciate (rise in value) against other currencies.

In a floating system, the central bank does not automatically fix the exchange rate; it is market-determined. The exchange rate will change in response to trade flows. The currency will appreciate (not depreciate) because more people want to buy it to pay for the increased exports. The amount being produced is irrelevant to the exchange rate; it is the demand from foreign buyers and the resulting currency transactions that matter.

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 domestic steel producers may become inefficient without competitive pressure.

Protectionism shields domestic firms from foreign competition. Without the pressure to match the prices or quality of foreign rivals, domestic producers have less incentive to innovate, cut costs or improve efficiency. Over time this can make the protected industry weaker rather than stronger.

Protection tends to raise, not lower, domestic prices because cheaper imports are restricted. The whole point of protectionism is to prevent foreign firms from gaining market share, not to increase it. The government would still collect tariff revenue if tariffs are the instrument used, so it would not lose all tariff revenue.

The drought decreases supply (leftward shift of the supply curve), which alone would raise price and reduce quantity. The health report increases demand (rightward shift of the demand curve), which alone would raise both price and quantity. Both shifts push price up, so price will definitely rise. However, the effect on quantity is uncertain - supply decreasing pushes quantity down while demand increasing pushes it up. The net effect depends on the relative size of the shifts.

The multiplier effect occurs when an initial injection of spending leads to a larger final increase in national income. The $10 billion of government spending creates income that is re-spent, generating further rounds of spending and output throughout the economy.

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 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 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.

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 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.

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 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.

Liquidity refers to how quickly and easily an asset can be converted into cash without losing value. A fixed-term savings bond locks money away for a set period, and early withdrawal typically incurs a penalty. A current account deposit can be accessed immediately. Earning a higher interest rate explains why people hold bonds but not why they are less liquid. Neither savings bonds nor current account deposits are used directly in shops.

Occupational mobility refers to the ability of workers to move between different types of jobs. Subsidised retraining programmes directly help workers acquire the skills needed for new occupations, increasing their mobility. Reducing education spending would decrease mobility. Minimum wage changes and income tax rates primarily affect wage levels rather than workers' ability to switch occupations.

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 worker remittances, which are recorded on the current account.

Worker remittances are transfers of money sent by workers living abroad back to their families in their home country. These are classified as secondary income (current transfers) on the current account of the balance of payments.

Remittances are an important source of foreign currency for many developing countries and can significantly improve the current account balance. They represent a credit (inflow) on the receiving country's current account.

Portfolio investments involve buying financial assets (shares, bonds) in foreign markets and are recorded on the financial account. Foreign direct investment (FDI) involves establishing or acquiring business operations abroad, also on the financial account. Capital transfers on the capital account cover items like debt forgiveness and migrant transfers of assets, which are different from regular wage remittances.

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.

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 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 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.

Before: $50 000 x 100 = 5 000 000 yen. After: $50 000 x 120 = 6 000 000 yen. The yen has depreciated (more yen needed per dollar), making imports from the US more expensive for Japanese firms.

The correct answer is a large proportion of economic activity occurs in the informal sector.

In many developing countries, a significant share of workers are self-employed, work in small family businesses, or are paid in cash without formal records. This informal sector activity is difficult to monitor and tax because there are no payroll systems, official accounts, or tax registration for these workers. Without reliable records of earnings, governments cannot assess or collect income tax effectively.

High interest rates relate to monetary policy, not tax collection. Fixed exchange rates affect the currency market, not the ability to collect taxes from citizens. Small populations would mean fewer taxpayers, but would not inherently make tax collection more difficult per person.

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 GDP per capita can overstate improvements in well-being if environmental costs are ignored.

The data shows that as GDP per capita rose between Year 1 and Year 20, the environmental quality index fell. This reveals a trade-off: economic growth generated higher incomes but at the cost of environmental degradation. GDP per capita captures the income gain but does not subtract the environmental loss. If we judge well-being by GDP alone, we overstate how much better off people actually are, because the deterioration in air quality, water purity, and natural habitats reduces quality of life.

The other options are incorrect. Environmental quality clearly affects living standards through health, recreation, and resource availability. Countries do not always have to choose between growth and protection; green technologies can achieve both. Economic growth does not always improve environmental quality; the data here shows the opposite.

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 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.
