As a percentage of GDP, Australia's total imports plus total exports, is approximately
75%.
45%.
25%.
5%.
Reveal Answer
75%.
Incorrect. A trade-to-GDP ratio of 75% is much higher than Australia's and is typically seen in smaller, highly open economies or major global trade hubs.
45%.
Correct. Australia's total trade (imports plus exports) as a percentage of GDP historically hovers around 40% to 45%, reflecting its moderate level of global trade openness.
25%.
Incorrect. A ratio of 25% is too low for Australia and is more characteristic of very large economies with massive domestic markets, such as the United States.
5%.
Incorrect. A trade-to-GDP ratio of 5% is exceptionally low and does not accurately represent the trade openness of any modern developed economy.
Using the demand and supply model, demonstrate and explain the short- and long-term effects of a reduction in tariffs and subsidies on a trade-protected economy.
Reveal Answer
Answer(s) could include:
Tariff diagram:
- price – Y axis, quantity – X axis
- tariff originally set to raise price in market and raise government revenue eliminated
- domestic supply falls, imported supply rises
- domestic consumption expands.
Tariff explanation and short-term effects:
- reduction in price for consumers and expansion in domestic consumption
- switches consumption from domestic producers to imports
- decrease the cost for domestic producers if an imported capital item
- domestic suppliers sell less for less
- possible reduction of government revenue from tariff
- reference to DWL and market effects (CS, PS, TS).
Subsidy diagram:
- price – Y axis, quantity – X axis
- supply curve shifts to the left for domestic suppliers (decrease)
- increased gap between local supply and local demand
- price remains at world price
- domestic consumption is unchanged.
Subsidy explanation and short-term effects:
- increased domestic costs as subsidy removed
- lower competitiveness against imports
- decreased domestic production
- imports increase
- reduction of Government subsidy cost.
- reference to DWL and market effects (CS, PS, TS).
Longer term effects of tariff elimination:
- reduction in retaliatory tariffs
- less Government revenue for spending in other areas
- increase in economic output and employment through increased free trade
- structural change in the economy as resources such as labour shift from uncompetitive trade exposed industries to competitive industries
- higher national income.
Longer term effects of subsidy elimination:
- efficient producers are advantaged
- decreased burden on the tax payer
- promotes innovation in the economy
- government expenditure can be re-allocated to more effective areas of social need.

An improvement in Australia's current account balance is most likely to occur when
the trade balance surplus increases.
the terms of trade deteriorate.
the Australian dollar appreciates.
China's economic growth slows.
Reveal Answer
the trade balance surplus increases.
The trade balance (exports minus imports) is a major component of the current account, so an increase in the trade surplus directly improves the overall current account balance.
the terms of trade deteriorate.
A deterioration in the terms of trade means export prices fall relative to import prices, which typically decreases export revenue and worsens the current account balance.
the Australian dollar appreciates.
An appreciation of the Australian dollar makes exports more expensive for foreign buyers and imports cheaper for domestic consumers, which generally reduces net exports and worsens the current account balance.
China's economic growth slows.
Slower economic growth in China, a major trading partner, would reduce demand for Australian exports, thereby worsening Australia's trade balance and current account.
Australia's international competitiveness will most likely increase if
the Australian dollar appreciates relative to our trading partners' currencies.
the Australian Government spends more on ports and railroads.
Australian workers' wages increase faster than their productivity.
Gross Domestic Product (GDP) growth is higher in Australia than in other countries.
Reveal Answer
the Australian dollar appreciates relative to our trading partners' currencies.
An appreciation of the Australian dollar makes exports more expensive for foreign buyers, which decreases rather than increases international competitiveness.
the Australian Government spends more on ports and railroads.
Government investment in infrastructure like ports and railroads reduces transportation costs and improves supply chain efficiency, making Australian exports more competitive globally.
Australian workers' wages increase faster than their productivity.
When wage growth outpaces productivity growth, unit labor costs increase, making Australian goods more expensive to produce and less competitive internationally.
Gross Domestic Product (GDP) growth is higher in Australia than in other countries.
Higher GDP growth does not directly improve international competitiveness and could potentially reduce it if the growth leads to higher domestic inflation.
Australia experiences improved international competitiveness when there is
a higher domestic inflation rate than its trading partners.
an appreciation of the Australian dollar.
an improvement in labour productivity.
higher domestic real wages growth than its trading partners.
Reveal Answer
a higher domestic inflation rate than its trading partners.
A higher domestic inflation rate increases the prices of Australian goods relative to those of its trading partners, which reduces international competitiveness.
an appreciation of the Australian dollar.
An appreciation of the Australian dollar makes Australian exports more expensive for foreign buyers, decreasing international competitiveness.
an improvement in labour productivity.
An improvement in labour productivity lowers unit labour costs, allowing Australian firms to produce goods more efficiently and increasing their competitiveness in global markets.
higher domestic real wages growth than its trading partners.
Higher domestic real wages growth increases the cost of production for Australian firms, which makes their goods more expensive and less competitive internationally unless matched by productivity gains.
An increase in foreign investment into Australia will result in a
credit in the financial account and an appreciation of the Australian dollar (AUD).
credit in the financial account and a depreciation of the Australian dollar (AUD).
debit in the financial account and an appreciation of the Australian dollar (AUD).
debit in the financial account and a depreciation of the Australian dollar (AUD).
Reveal Answer
credit in the financial account and an appreciation of the Australian dollar (AUD).
An inflow of foreign investment is recorded as a credit in the financial account. Additionally, foreigners must purchase Australian dollars to invest, increasing demand for the currency and causing it to appreciate.
credit in the financial account and a depreciation of the Australian dollar (AUD).
While the investment is correctly identified as a credit in the financial account, the increased demand for Australian dollars will cause the currency to appreciate, not depreciate.
debit in the financial account and an appreciation of the Australian dollar (AUD).
Foreign investment into Australia represents an inflow of funds, which is recorded as a credit, not a debit, in the financial account.
debit in the financial account and a depreciation of the Australian dollar (AUD).
This option is entirely incorrect; an inflow of foreign investment is recorded as a credit (not a debit) and causes the Australian dollar to appreciate (not depreciate) due to increased demand.
Which of the following statements regarding the composition and direction of Australian trade is correct?
Australia’s largest two-way trading partner is the European Union.
There has been a recent shift in the direction of Australia’s trade toward Asia over the last ten years.
Coal is Australia’s largest export commodity.
Since 2020, tourism has been Australia’s largest import category.
Reveal Answer
Australia’s largest two-way trading partner is the European Union.
China, not the European Union, is Australia's largest two-way trading partner, accounting for a significant portion of both imports and exports.
There has been a recent shift in the direction of Australia’s trade toward Asia over the last ten years.
Over the last decade, Australia's trade has increasingly shifted toward Asian economies, particularly China, Japan, and South Korea, driven by their rapid industrialization and demand for resources.
Coal is Australia’s largest export commodity.
Iron ore, not coal, is consistently Australia's largest export commodity by value, largely driven by strong demand from Asian steel manufacturers.
Since 2020, tourism has been Australia’s largest import category.
Tourism (a service export/import) dropped significantly in 2020 due to global COVID-19 travel restrictions and border closures, meaning it was not the largest import category.
The table below shows the production of beef and corn in two countries.
| Beef | Corn | ||
|---|---|---|---|
| Country A | 5000 | or | 5000 |
| Country B | 2000 | or | 4000 |
Based on the information in the table, what is the opportunity cost of Country B producing one extra unit of corn?
1 unit of beef
2 units of beef
0.5 units of beef
1 unit of corn
Reveal Answer
1 unit of beef
This is incorrect. One unit of beef is the opportunity cost of producing one unit of corn for Country A (), not Country B.
2 units of beef
This is incorrect. Two units of beef is the inverse of the correct calculation; it represents Country B's opportunity cost of producing one unit of beef ( units of corn).
0.5 units of beef
This is correct. Country B must give up 2000 units of beef to produce 4000 units of corn, making the opportunity cost units of beef per unit of corn.
1 unit of corn
This is incorrect. Opportunity cost must be measured in terms of the alternative good given up, which in this case is beef, not corn.
When Australia records a surplus on its capital and financial account
capital machinery used to produce other goods has usually been imported from overseas.
Australian investment overseas has been greater than foreign investment in Australia.
Australian holdings of foreign assets have not increased as much as foreign holdings of Australian assets.
equity has been the preferred form of foreign investment rather than debt.
Reveal Answer
capital machinery used to produce other goods has usually been imported from overseas.
Importing capital machinery is recorded as a debit in the goods section of the current account, not the capital and financial account.
Australian investment overseas has been greater than foreign investment in Australia.
If Australian investment overseas exceeds foreign investment in Australia, there is a net outflow of funds, which would result in a deficit on the capital and financial account, not a surplus.
Australian holdings of foreign assets have not increased as much as foreign holdings of Australian assets.
A surplus on the capital and financial account indicates a net inflow of funds, meaning foreign investment in Australia (foreign holdings of Australian assets) exceeds Australian investment abroad.
equity has been the preferred form of foreign investment rather than debt.
The composition of foreign investment (whether it is equity or debt) does not determine if the account is in surplus or deficit; only the net total flow of funds matters.
If Australia's terms of trade increase, which of the following must be true as a result?
Australia can import fewer real goods for a unit of its exports.
Australia can import more real goods for a unit of its exports.
The index of export prices has decreased.
The index of import prices has increased.
Reveal Answer
Australia can import fewer real goods for a unit of its exports.
An increase in the terms of trade means export prices have risen relative to import prices, allowing the country to purchase more, not fewer, imports per unit of exports.
Australia can import more real goods for a unit of its exports.
The terms of trade measures the ratio of export prices to import prices. An increase means a given volume of exports generates relatively more revenue, which can now purchase a larger volume of imported goods.
The index of export prices has decreased.
An increase in the terms of trade could occur if export prices increase, or if they decrease but at a slower rate than import prices. Therefore, it is not a requirement that export prices have decreased.
The index of import prices has increased.
An increase in the terms of trade could happen if import prices decrease, or if they increase but at a slower rate than export prices. Thus, it is not a requirement that import prices have increased.
Which one of the following is most likely to cause an appreciation in the value of the Australian dollar?
a fall in global commodity prices
a downgrade in Australia's credit rating
an increase in imports relative to exports
higher interest rates in Australia relative to other countries
Reveal Answer
a fall in global commodity prices
Incorrect. Australia is a major commodity exporter, so a fall in global commodity prices reduces export revenue. This decreases demand for the Australian dollar, causing it to depreciate rather than appreciate.
a downgrade in Australia's credit rating
Incorrect. A credit rating downgrade makes Australian financial assets riskier and less attractive to foreign investors. This leads to capital outflows and a depreciation of the currency.
an increase in imports relative to exports
Incorrect. An increase in imports relative to exports means more Australian dollars are being sold to purchase foreign currency. This increases the supply of the Australian dollar, leading to its depreciation.
higher interest rates in Australia relative to other countries
Correct. Higher interest rates attract foreign investors seeking better returns on their capital. This increases the demand for the Australian dollar, driving up its exchange rate value.
Australia’s foreign debt represents mainly the extent to which
foreign residents own Australian assets.
Australia owns foreign assets.
Australia owes the rest of the world.
Australian companies borrow from overseas.
Reveal Answer
foreign residents own Australian assets.
Foreign ownership of Australian assets represents foreign equity or investment, which is a different component of foreign liabilities than foreign debt.
Australia owns foreign assets.
Australia owning foreign assets represents Australian investment abroad (foreign assets), not what Australia owes to other countries.
Australia owes the rest of the world.
Foreign debt is defined as the total outstanding amount of money that a country's residents, businesses, and government owe to foreign creditors.
Australian companies borrow from overseas.
While borrowing by Australian companies is a significant component of foreign debt, this option is incomplete because foreign debt also includes borrowing by the government and other sectors.
Which of the following factors has facilitated growth in the value of Australia's exports in recent years?
decreased production costs of manufactured goods
an appreciation of the Australian dollar
trade liberalisation
increased trade barriers
Reveal Answer
decreased production costs of manufactured goods
Australia's export growth has been driven primarily by commodities and services, not manufactured goods, as it generally faces higher manufacturing production costs compared to other nations.
an appreciation of the Australian dollar
An appreciation of the Australian dollar makes its exports more expensive to foreign buyers, which typically reduces international competitiveness and hinders export growth.
trade liberalisation
Trade liberalisation, such as the implementation of free trade agreements, reduces tariffs and quotas, making Australian exports more competitive and accessible in global markets.
increased trade barriers
Increased trade barriers, such as tariffs or quotas imposed by trading partners, would restrict trade and negatively impact the volume and value of Australia's exports.
The table below shows the production possibilities of coal and iron ore in two countries.
| Coal (tonnes) | Iron ore (tonnes) | ||
|---|---|---|---|
| Country A | 50 | or | 100 |
| Country B | 80 | or | 320 |
According to the above table, country
B has a comparative advantage in producing coal.
A has an absolute advantage in producing iron ore.
B has a comparative advantage in producing iron ore.
A has a comparative advantage in producing iron ore.
Reveal Answer
B has a comparative advantage in producing coal.
Country A, not Country B, has a comparative advantage in producing coal because its opportunity cost ( tonnes of iron ore per tonne of coal) is lower than Country B's ( tonnes of iron ore per tonne of coal).
A has an absolute advantage in producing iron ore.
Country B has an absolute advantage in producing iron ore because it can produce a maximum of tonnes, which is greater than Country A's maximum of tonnes.
B has a comparative advantage in producing iron ore.
Country B has a comparative advantage in producing iron ore because its opportunity cost ( tonnes of coal per tonne of iron ore) is lower than Country A's opportunity cost ( tonnes of coal per tonne of iron ore).
A has a comparative advantage in producing iron ore.
Country A does not have a comparative advantage in producing iron ore because its opportunity cost ( tonnes of coal) is higher than Country B's opportunity cost ( tonnes of coal).
The payment of dividends to Australians holding shares in foreign companies will be recorded in the balance of payments as
a credit in the capital and financial account.
a debit in the capital and financial account.
a credit in the current account.
a debit in the current account.
Reveal Answer
a credit in the capital and financial account.
The capital and financial account records the purchase or sale of the shares themselves (the asset), not the income generated by holding them.
a debit in the capital and financial account.
The capital and financial account deals with asset transactions, not income flows. Additionally, a debit would represent an outflow of funds, whereas receiving dividends is an inflow.
a credit in the current account.
Dividends received from foreign investments are classified as primary income. Since the money is flowing into Australia, it is recorded as a credit (inflow) in the current account.
a debit in the current account.
While dividends are recorded in the current account, a debit represents an outflow of money. This would apply if Australian companies were paying dividends to foreign shareholders.
