Question 1Economics (Stage 6)

Which policy tool is classified as monetary policy?

  1. Increasing the rate of taxation on company profits
  2. Building new transport infrastructure
  3. Purchasing government securities in the open market Correct answer.
  4. Raising the minimum wage for low-income workers

Explanation

Monetary policy is conducted by the central bank and operates through the cash rate and liquidity in the financial system. Buying government securities in the open market injects liquidity and lowers the cash rate, which is a standard monetary instrument. Taxation, infrastructure spending and wage regulation are fiscal or labour-market measures controlled by government.

Question 2Economics (Stage 6)

A country's consumer price index rises from 120 to 126 over one year. What is the inflation rate?

  1. 5.0 per cent Correct answer.
  2. 1.05 per cent
  3. 4.8 per cent
  4. 6.0 per cent

Explanation

The inflation rate is the percentage change in the price index between the two periods, calculated as (126 − 120) ÷ 120 × 100. This gives 6 ÷ 120 × 100, which equals 5.0 per cent. Dividing by the initial index rather than the new index is essential for a correct result.

Question 3Economics (Stage 6)

What does a movement along a demand curve represent?

  1. A change in the price of a substitute good
  2. A change in household income levels
  3. A change in price of the good itself Correct answer.
  4. A change in consumer preferences for the good

Explanation

A movement along a demand curve is caused solely by a change in the good's own price, changing the quantity demanded. Shifts of the curve occur when non-price factors such as income, preferences or substitute prices change. Keeping this distinction clear is fundamental to demand analysis.

Question 4Economics (Stage 6)

Which group is most likely to benefit from an unexpected rise in the inflation rate?

  1. Savers holding funds in low-interest accounts
  2. Banks holding long-term fixed-interest loans
  3. Households with large fixed-rate mortgages Correct answer.
  4. Retirees living on fixed nominal pensions

Explanation

Unexpected inflation erodes the real value of debt, so borrowers with fixed nominal obligations gain while lenders lose. Households with fixed-rate mortgages repay in money that is worth less than anticipated. Fixed-income recipients and savers suffer because their nominal returns buy fewer goods.

Question 5Economics (Stage 6)

Which of the following is counted in Australia's labour force?

  1. A full-time student who is not looking for work
  2. An unpaid volunteer at a charity shop
  3. A part-time worker seeking additional hours Correct answer.
  4. A retiree who has stopped seeking employment

Explanation

The labour force comprises all employed persons plus those unemployed who are actively seeking work. A part-time worker is employed and therefore inside the labour force, even if seeking more hours. People not working and not actively seeking work are outside the labour force.

Question 6Economics (Stage 6)

What is the main purpose of the Goods and Services Tax in Australia?

  1. To stabilise the cash rate in financial markets
  2. To raise revenue for state and territory governments Correct answer.
  3. To redistribute income from high to low earners
  4. To discourage consumption of imported goods

Explanation

The GST is a broad-based indirect tax whose revenue is distributed to the states and territories to fund public services. It is not designed as a redistributive tool or a trade barrier. It operates independently of monetary policy settings.

Question 7Economics (Stage 6)

A depreciation of the Australian dollar is most likely to cause which immediate effect?

  1. The volume of imports into Australia rises sharply
  2. Australian exports become cheaper for foreign buyers Correct answer.
  3. Australian exports become more expensive overseas
  4. Imported goods become cheaper for Australian consumers

Explanation

A depreciation lowers the foreign-currency price of Australian goods, improving the price competitiveness of exports abroad. It simultaneously raises the domestic price of imports, which tends to reduce import volumes. These price effects form the basis of the expenditure-switching channel.

Question 8Economics (Stage 6)

Which statement best describes opportunity cost?

  1. The value of the next best alternative forgone Correct answer.
  2. The total cost of producing an extra unit
  3. The cost of resources that cannot be recovered
  4. The money paid for a good at the time of purchase

Explanation

Opportunity cost is the value of the next best alternative sacrificed when a choice is made. It reflects scarcity and underlies the production possibility frontier. It is broader than monetary cost because it includes forgone benefits.

Question 9Economics (Stage 6)

A government increases spending on infrastructure during a recession. Which policy stance does this represent?

  1. Expansionary fiscal policy Correct answer.
  2. Expansionary monetary policy
  3. Contractionary monetary policy
  4. Contractionary fiscal policy

Explanation

Higher government spending is a fiscal action that adds directly to aggregate demand, so it is expansionary fiscal policy. The aim is to close a negative output gap and reduce cyclical unemployment. Monetary policy would instead involve changes to interest rates or liquidity.

Question 10Economics (Stage 6)

An economy has a marginal propensity to consume of 0.8. What is the value of the simple multiplier?

  1. 0.2
  2. 5.0 Correct answer.
  3. 4.0
  4. 1.25

Explanation

The simple multiplier equals 1 ÷ (1 − MPC). With an MPC of 0.8, the marginal propensity to save is 0.2 and 1 ÷ 0.2 equals 5.0. This means an initial injection generates five times that amount in total national income.

Question 11Economics (Stage 6)

Which situation would shift the aggregate supply curve to the right?

  1. An increase in consumer confidence
  2. A fall in the cost of key energy inputs Correct answer.
  3. A rise in nominal wages across all industries
  4. A rise in the general price level

Explanation

A fall in input costs lowers unit production costs, allowing firms to supply more output at each price level, shifting aggregate supply right. This is a positive supply shock that raises output and reduces inflationary pressure. Wage rises and price-level changes do not produce this cost-reducing effect.

Question 12Economics (Stage 6)

The Reserve Bank raises the cash rate. Which transmission channel acts most directly on household spending?

  1. Higher import prices raise the consumer price index
  2. Lower company profits reduce dividend payments
  3. A stronger exchange rate reduces export volumes
  4. Higher mortgage repayments reduce disposable income Correct answer.

Explanation

Higher interest rates increase repayments on variable-rate loans, cutting household disposable income and consumption. This cash-flow channel operates quickly and directly on spending. Exchange-rate and profit effects are indirect and slower to influence household demand.

Question 13Economics (Stage 6)

A country's terms of trade improve. What does this indicate?

  1. The balance on goods and services has turned negative
  2. Export prices have risen relative to import prices Correct answer.
  3. The exchange rate has depreciated against trading partners
  4. Import volumes have fallen below export volumes

Explanation

The terms of trade measure the ratio of export prices to import prices, so an improvement means each unit of exports buys more imports. This raises real national income for a given volume of trade. It is independent of trade volumes and the overall trade balance.

Question 14Economics (Stage 6)

Which policy combination would most reduce structural unemployment?

  1. Expanding training and apprenticeship programs Correct answer.
  2. Cutting interest rates to stimulate short-run demand
  3. Increasing unemployment benefit payment levels
  4. Raising tariffs to protect domestic manufacturing

Explanation

Structural unemployment arises from mismatches between workers' skills and available jobs, so education and training policies address the cause directly. Demand stimulus mainly reduces cyclical unemployment. Protection and higher benefits do not resolve skill mismatches.

Question 15Economics (Stage 6)

What is the effect of a quota imposed on imported goods?

  1. It limits import quantity and raises the domestic price Correct answer.
  2. It generates revenue for the exporting country's government
  3. It raises the volume of imports permitted
  4. It lowers the domestic price of the imported good

Explanation

A quota sets a maximum quantity of imports, restricting supply and pushing the domestic price above the world price. Domestic producers gain while consumers lose through higher prices and reduced choice. Unlike a tariff, a quota does not automatically generate revenue for the importing government.

Question 16Economics (Stage 6)

Which item is recorded as a credit in Australia's balance of payments current account?

  1. Export earnings from the sale of iron ore abroad Correct answer.
  2. Imports of motor vehicles from Japan
  3. Spending by Australian tourists travelling overseas
  4. Income paid to foreign investors on Australian assets

Explanation

Export earnings are credits because they represent an inflow of foreign exchange from the sale of goods abroad. Income paid overseas and imports are debits because they represent outflows. The current account records these flows in the goods, services, income and transfers categories.

Question 17Economics (Stage 6)

An increase in the supply of Australian dollars on foreign exchange markets, all else equal, will most likely cause which outcome?

  1. A rise in the cash rate set by the central bank
  2. A depreciation of the Australian dollar Correct answer.
  3. No change in the exchange rate
  4. An appreciation of the Australian dollar

Explanation

Greater supply of a currency lowers its equilibrium price in foreign exchange markets, which is a depreciation. The additional supply typically arises from higher capital outflows or import payments. Central bank interest rate settings are a separate policy decision.

Question 18Economics (Stage 6)

Which measure best captures the distribution of income within a country?

  1. The current account deficit as a share of GDP
  2. The labour force participation rate
  3. The Gini coefficient Correct answer.
  4. The consumer price index

Explanation

The Gini coefficient summarises inequality on a scale from 0, complete equality, to 1, complete inequality, and is derived from the Lorenz curve. It therefore measures how evenly income is distributed among households. The other indicators describe prices, labour market participation or external balance.

Question 19Economics (Stage 6)

A government reduces income tax rates for low-income earners while cutting welfare payments by a similar amount. What is the likely effect on the income distribution?

  1. It will reduce the Gini coefficient to zero
  2. It will have no effect because the two measures offset perfectly
  3. It may worsen inequality because the lost transfers can exceed the tax saving Correct answer.
  4. It will certainly make the distribution more equal

Explanation

Progressive transfers typically provide proportionally more to low-income households than a modest tax cut, so replacing transfers with tax relief can widen the income gap. The net effect depends on the size of each change, so it cannot be assumed to improve equality. A Gini coefficient of zero would imply perfect equality, which is unrealistic.

Question 20Economics (Stage 6)

Which statement about the Lorenz curve is correct?

  1. A straight diagonal line represents maximum inequality
  2. A curve closer to the diagonal line indicates greater inequality
  3. The curve can be used to calculate the inflation rate
  4. The curve plots cumulative income share against cumulative population share Correct answer.

Explanation

The Lorenz curve plots the cumulative share of income received against the cumulative share of the population, ranked from poorest to richest. Its distance from the diagonal line of perfect equality underlies the Gini coefficient. A bowed curve further from the diagonal indicates greater inequality.

Question 21Economics (Stage 6)

An economy is at full employment and the government increases spending financed by borrowing. According to crowding-out theory, what is the likely result?

  1. Private investment rises because interest rates fall
  2. The multiplier effect becomes larger than usual
  3. The price level falls because demand declines
  4. Higher interest rates reduce private investment Correct answer.

Explanation

Government borrowing raises demand for loanable funds, pushing interest rates up and displacing some private investment. This is the crowding-out mechanism that reduces the net demand impact of fiscal expansion. At full employment, the effect is stronger because resources are already fully utilised.

Question 22Economics (Stage 6)

A central bank simultaneously sells government securities and the government runs a large budget surplus. What is the combined likely effect on aggregate demand?

  1. The effect is indeterminate because the two tools are unrelated
  2. Both actions are expansionary, so demand rises strongly
  3. Both actions are contractionary, so demand is dampened Correct answer.
  4. The actions offset each other exactly, leaving demand unchanged

Explanation

Selling securities drains liquidity and raises interest rates, while a budget surplus withdraws demand from the circular flow. Both are contractionary, so their effects reinforce one another in reducing aggregate demand. Exact offsetting would require opposing policy stances, not aligned ones.

Question 23Economics (Stage 6)

A nation's production possibility frontier shifts outward for capital goods but remains unchanged for consumer goods. What does this imply about its growth strategy?

  1. It has experienced a fall in the quality of its labour force
  2. It has increased current consumption at the expense of capital formation
  3. It has become less efficient in producing consumer goods
  4. It has sacrificed current consumption to expand future productive capacity Correct answer.

Explanation

An outward shift concentrated in capital goods reflects expanded capacity to produce investment goods, typically achieved by forgoing current consumption. This raises future output potential because capital goods enhance productive capacity. Consumer goods capacity is unchanged, so current consumption opportunities have not expanded.

Question 24Economics (Stage 6)

Which scenario best illustrates the operation of automatic stabilisers?

  1. The central bank lowers the cash rate to boost spending
  2. The government introduces a new tariff on imported steel
  3. Tax receipts fall and welfare payments rise as unemployment increases Correct answer.
  4. Parliament passes a new stimulus package during a downturn

Explanation

Automatic stabilisers are built-in features of the budget that respond to the economic cycle without new legislation. In a downturn, lower incomes reduce tax receipts while higher unemployment raises welfare payments, cushioning the fall in demand. Discretionary measures require deliberate policy decisions.

Question 25Economics (Stage 6)

A country experiences a rise in its exchange rate alongside a fall in global demand for its exports. Which combination best describes the likely impact on its trade balance?

  1. Exports fall and imports fall, with an indeterminate net effect
  2. Exports rise and imports fall, improving the trade balance
  3. Exports fall and imports rise, worsening the trade balance Correct answer.
  4. Exports and imports both rise, leaving the balance unchanged

Explanation

A higher exchange rate makes exports dearer abroad and imports cheaper at home, while weaker global demand further reduces export volumes. Both forces point to lower exports and higher imports, which worsens the trade balance. The combined effect is clearly negative rather than ambiguous.

Question 26Economics (Stage 6)

Which of the following is classified as a factor of production in economics?

  1. Government bonds
  2. Shares
  3. Capital Correct answer.
  4. Money

Explanation

Factors of production are the inputs used to produce goods and services, conventionally grouped as land, labour, capital and enterprise. Capital refers to produced means of production such as machinery and equipment. Money and financial assets are not themselves productive inputs; they only finance purchases of resources.

Question 27Economics (Stage 6)

A demand curve for a normal good slopes downward primarily because of which effect?

  1. A fall in price raises real purchasing power, increasing quantity demanded Correct answer.
  2. A fall in price reduces the cost of production for firms
  3. A fall in price increases consumer incomes in nominal terms
  4. A fall in price shifts the supply curve to the left

Explanation

The law of demand rests on the substitution effect and the income effect. When price falls, the good becomes cheaper relative to substitutes, and consumers' real income rises so they can buy more. Nominal incomes are unchanged, so the answer referring to nominal income is incorrect.

Question 28Economics (Stage 6)

Which of the following is included in the calculation of Australia's GDP using the expenditure approach?

  1. Government expenditure on new roads Correct answer.
  2. A pension payment to a retired worker
  3. Purchase of a second-hand car from a private seller
  4. An increase in the value of shares held by households

Explanation

The expenditure approach sums consumption, investment, government expenditure and net exports on final goods and services produced in the period. Government spending on new infrastructure is a final good produced domestically. Transfer payments, second-hand sales and share price movements do not create new output.

Question 29Economics (Stage 6)

Which of the following best describes cyclical unemployment?

  1. Unemployment caused by workers lacking current skills
  2. Unemployment caused by seasonal changes in demand
  3. Unemployment caused by workers moving between jobs
  4. Unemployment caused by a downturn in aggregate demand Correct answer.

Explanation

Cyclical unemployment arises when the economy operates below its potential output because aggregate demand is insufficient. It rises during contractions and falls during recoveries. The other options describe structural, seasonal and frictional unemployment respectively.

Question 30Economics (Stage 6)

Inflation is best defined as which of the following?

  1. An increase in the money supply alone
  2. A sustained increase in the general price level over time Correct answer.
  3. A fall in the purchasing power of one particular currency
  4. A one-off rise in the price of a single good

Explanation

Inflation refers to a sustained rise in the general price level, measured by indices such as the consumer price index. A rise in one good's price is not inflation unless it spreads across the economy. Money supply growth may contribute to inflation but is not its definition.

Question 31Economics (Stage 6)

Which of the following is a leakage from the circular flow of income?

  1. Government transfer payments
  2. Export revenue
  3. Firms' investment spending
  4. Household saving Correct answer.

Explanation

Leakages withdraw income from the circular flow before it is spent on domestic output; they include saving, taxation and imports. Injections add to the flow and include investment, government spending and exports. Saving is therefore the only leakage among the options.

Question 32Economics (Stage 6)

A country's currency depreciates on foreign exchange markets. Which group is most likely to benefit directly?

  1. Domestic consumers buying imported goods
  2. Domestic exporters selling in foreign markets Correct answer.
  3. Domestic travellers purchasing foreign currency
  4. Foreign investors holding assets in the domestic currency

Explanation

A depreciation makes domestic goods cheaper for foreign buyers, improving the price competitiveness of exports. Imported goods become more expensive for domestic residents. Holders of domestic currency assets lose value in foreign currency terms.

Question 33Economics (Stage 6)

Which of the following is an example of a progressive tax?

  1. A tax levied at the same percentage rate on all incomes
  2. A tax whose average rate rises as income rises Correct answer.
  3. A tax levied only on goods and services
  4. A tax charged at a constant amount per person regardless of income

Explanation

A progressive tax takes a larger proportion of income from higher-income earners, so its average rate rises with income. A proportional tax applies the same rate to all, while a regressive tax takes a larger proportion from lower incomes. A tax on goods and services is generally regressive in effect.

Question 34Economics (Stage 6)

A government imposes a price ceiling below the equilibrium price of a good. Which outcome is most likely?

  1. The equilibrium price will fall to the ceiling without any market effect
  2. A surplus arises because quantity supplied exceeds quantity demanded
  3. Quantity supplied will increase as producers respond to higher prices
  4. A shortage arises because quantity demanded exceeds quantity supplied Correct answer.

Explanation

A binding price ceiling set below equilibrium prevents the price from rising to clear the market. At the lower price, quantity demanded exceeds quantity supplied, creating a shortage. A surplus would occur with a price floor set above equilibrium.

Question 35Economics (Stage 6)

An economy's marginal propensity to save is 0.25. What is the value of the simple multiplier?

  1. 1.33
  2. 0.75
  3. 0.25
  4. 4 Correct answer.

Explanation

The simple multiplier equals one divided by the marginal propensity to save, since the marginal propensity to consume equals 1 minus the marginal propensity to save. With a marginal propensity to save of 0.25, the multiplier is 1 divided by 0.25, which equals 4. A larger leakage reduces the multiplier.

Question 36Economics (Stage 6)

Which of the following would cause a movement along the aggregate demand curve rather than a shift of the curve?

  1. An increase in government spending
  2. A rise in business investment confidence
  3. A fall in the general price level Correct answer.
  4. An increase in export demand from overseas

Explanation

A change in the general price level alters the quantity of real output demanded, producing a movement along the aggregate demand curve. Changes in spending components such as government spending, investment or exports shift the curve itself. This distinction separates price effects from demand shocks.

Question 37Economics (Stage 6)

A country's consumer price index rises from 120 to 126 over a year. What is the inflation rate?

  1. 1.05 per cent
  2. 5 per cent Correct answer.
  3. 6 per cent
  4. 4.8 per cent

Explanation

The inflation rate is the percentage change in the price index, calculated as the change divided by the initial index multiplied by 100. The change is 6 points and the initial index is 120, giving 5 per cent. Using the final index as the base would give the wrong figure.

Question 38Economics (Stage 6)

The Reserve Bank of Australia sells government securities in the open market. What is the most likely immediate effect?

  1. Exchange settlement balances rise and the cash rate falls
  2. Exchange settlement balances fall and upward pressure is placed on the cash rate Correct answer.
  3. The government's budget deficit automatically increases
  4. The money supply expands as banks gain reserves

Explanation

When the central bank sells securities, buyers pay from their exchange settlement accounts, reducing the balances that banks hold at the Reserve Bank. Scarcity of these funds puts upward pressure on the cash rate in the overnight market. This is a contractionary open market operation.

Question 39Economics (Stage 6)

Which of the following transactions is recorded as a debit in Australia's balance of payments?

  1. An Australian firm receiving payment for exported services
  2. A foreign tourist spending money in Australia
  3. An Australian resident paying dividends to a foreign shareholder Correct answer.
  4. Foreign aid received by Australia from another country

Explanation

In balance of payments accounting, debits record outflows of value from the domestic economy, such as income paid abroad. Credits record inflows of value, such as export earnings or foreign spending in the domestic economy. Paying dividends overseas is therefore a debit.

Question 40Economics (Stage 6)

A firm's production creates pollution that affects nearby residents who are not compensated. This situation is best described as which of the following?

  1. A negative externality of production Correct answer.
  2. A public good provided by the firm
  3. A natural monopoly in production
  4. A positive externality of consumption

Explanation

A negative externality of production occurs when production imposes costs on third parties that are not reflected in the firm's private costs. Pollution affecting residents without compensation is the classic example. Because the market price ignores these external costs, output tends to exceed the socially optimal level.

Question 41Economics (Stage 6)

Which of the following would most likely increase a country's labour force participation rate?

  1. An increase in the retirement age pension eligibility threshold
  2. A fall in the number of job vacancies advertised
  3. An expansion of affordable childcare services Correct answer.
  4. A rise in the minimum wage above market rates

Explanation

The participation rate measures the share of the working-age population in the labour force, either employed or actively seeking work. Affordable childcare lowers the barrier to paid work, particularly for parents, drawing more people into the labour force. Policies that discourage job search or reduce vacancies have the opposite effect.

Question 42Economics (Stage 6)

A country's nominal GDP rises by 7 per cent while its population grows by 3 per cent and the GDP deflator rises by 2 per cent. What is the approximate growth in real GDP per capita?

  1. About 7 per cent
  2. About 4 per cent
  3. About 12 per cent
  4. About 2 per cent Correct answer.

Explanation

Real GDP growth is approximately nominal growth minus inflation, giving 7 minus 2, or 5 per cent. Real GDP per capita growth then subtracts population growth of 3 per cent, leaving about 2 per cent. Failing to adjust for either inflation or population gives misleading figures.

Question 43Economics (Stage 6)

Which of the following best explains why a depreciation may worsen a country's trade balance in the short run before improving it?

  1. Domestic inflation immediately offsets all gains from the depreciation
  2. Import and export contracts are fixed in the short run, so quantities adjust slowly while prices change Correct answer.
  3. The depreciation raises the domestic currency value of exports instantly
  4. Foreign demand for exports is perfectly elastic in the short run

Explanation

The J-curve effect occurs because trade volumes are often locked into contracts in the short run. A depreciation raises the domestic cost of imports immediately while quantities change only gradually, so the trade balance may deteriorate first. Over time, as volumes respond, the balance can improve.

Question 44Economics (Stage 6)

An economy is experiencing demand-pull inflation. Which policy response is most consistent with standard macroeconomic management?

  1. The central bank raising the cash rate to reduce aggregate demand Correct answer.
  2. The central bank purchasing government bonds in the open market
  3. The government reducing the company tax rate to stimulate investment
  4. The government increasing infrastructure spending to boost output

Explanation

Demand-pull inflation arises when aggregate demand grows faster than the economy's productive capacity. Contractionary monetary policy raises interest rates, dampening consumption and investment and easing price pressure. Expansionary fiscal or monetary measures would add further to demand.

Question 45Economics (Stage 6)

A government introduces a subsidy per unit paid to producers of a merit good. Which outcome is most likely in the market for that good?

  1. The demand curve shifts right and the equilibrium quantity falls
  2. The demand curve shifts left and the equilibrium price falls
  3. The supply curve shifts right and the equilibrium price falls while quantity rises Correct answer.
  4. The supply curve shifts left and the equilibrium price rises

Explanation

A per-unit subsidy lowers producers' effective costs, shifting supply to the right. At the new equilibrium, price is lower and quantity traded is higher, encouraging consumption of the merit good. Subsidies affect supply rather than shifting the demand curve directly.

Question 46Economics (Stage 6)

A country with a fixed exchange rate runs persistent current account deficits and faces downward pressure on its currency. Which combination best describes the policy constraint this creates?

  1. Fiscal policy becomes completely ineffective under a fixed exchange rate
  2. Defending the peg requires higher interest rates, which may contract domestic activity Correct answer.
  3. The country must allow its currency to appreciate to correct the deficit
  4. The central bank can freely lower interest rates without affecting the exchange rate

Explanation

Under a fixed exchange rate, defending the currency against depreciation typically requires raising interest rates to attract capital inflows. Higher rates dampen domestic spending and can slow growth, creating a policy trade-off. Monetary policy is constrained because it must serve the exchange rate target.

Question 47Economics (Stage 6)

An increase in a country's structural budget deficit occurs while the economy moves into recession. Which interpretation is most accurate?

  1. The structural deficit always equals the actual deficit during a recession
  2. A larger structural deficit proves that fiscal policy has become more expansionary
  3. The structural balance measures only interest payments on public debt
  4. The structural balance isolates discretionary policy, while the actual balance also reflects cyclical effects Correct answer.

Explanation

The structural budget balance estimates what the budget position would be if the economy operated at potential output, isolating discretionary fiscal decisions. The actual balance includes cyclical movements in tax revenue and welfare spending. A widening actual deficit in a recession may therefore partly reflect automatic stabilisers rather than new policy.

Question 48Economics (Stage 6)

Which of the following best explains the concept of comparative advantage?

  1. A country should specialise in goods for which it has the largest domestic market
  2. A country should specialise in goods it can produce most cheaply in money terms
  3. A country should specialise where it produces more output per worker than any other country
  4. A country should specialise where its opportunity cost of production is lower than its trading partner's Correct answer.

Explanation

Comparative advantage is based on relative opportunity cost, not absolute productivity. A country gains from trade by specialising in goods for which it sacrifices less of other goods than its trading partner. Even a less productive country can benefit from trade on this basis.

Question 49Economics (Stage 6)

A government wants to reduce income inequality without reducing total hours worked. Which policy is most consistent with this objective?

  1. Raising the top marginal tax rate to very high levels without changing deductions
  2. Cutting welfare payments to lower-income households
  3. Increasing the progressivity of the income tax scale while broadening the tax base Correct answer.
  4. Introducing a flat tax rate on all income levels

Explanation

Greater progressivity shifts the tax burden towards higher-income earners, reducing after-tax inequality. Broadening the base allows revenue to be raised at lower marginal rates, limiting work disincentives. Extreme marginal rates or flat taxes can worsen equity or work incentives.

Question 50Economics (Stage 6)

The Reserve Bank of Australia lowers the cash rate, and commercial banks pass the reduction on to borrowers. Which sequence best describes the expected transmission to economic activity?

  1. Lower interest rates reduce disposable income and lower consumption
  2. Lower interest rates directly increase the government's budget surplus
  3. Lower interest rates raise the exchange rate and reduce net exports
  4. Lower borrowing costs raise consumption and investment, increasing aggregate demand and output Correct answer.

Explanation

Monetary easing reduces the cost of credit, encouraging households and firms to borrow and spend. Higher consumption and investment raise aggregate demand, which can lift output and employment. Exchange rate and fiscal effects are separate channels that do not follow this pattern.
