HSC Economics 2024

(a)(i) [1 mark]. At the world price of $10, domestic demand is 350 and domestic supply is 50, so imports fill the gap: 350 - 50 = 300 units.

(a)(ii) [1 mark]. A $20 tariff lifts the price to$30. At $30, domestic demand falls and domestic supply rises, narrowing imports to 100 units. Tariff revenue is the tariff times the quantity still imported:

(b) [3 marks]. Name: the Regional Comprehensive Economic Partnership (RCEP). The RCEP is a multilateral agreement of 15 member economies including Australia, China, Japan, the Republic of Korea, New Zealand and the ASEAN nations. One implication for Australia is improved market access for service exporters across all member economies, through common rules of origin and reduced barriers. This widens the export market for Australian services such as education and finance, supporting export income and jobs in those sectors. (AANZFTA, the CPTPP, PACER Plus, the WTO or APEC are equally acceptable.)

(c) [5 marks]. Protectionist policies of other countries (tariffs, subsidies and quotas on their imports) restrict access to overseas markets for Australian producers. This reduces foreign demand for Australian exports such as agricultural goods and resources, lowering export credits and worsening the balance on goods and services (a smaller surplus or larger deficit) within the current account.

There is a second-round effect through the net primary income account. If foreign protection slows global growth, demand for Australian mining output falls, reducing the profits of foreign-owned firms operating in Australia and so reducing the income debits sent overseas - a partial offset. Conversely, a reduction in global protection raises export demand and global growth, lifting export credits but also raising profits returned to foreign owners (higher net primary income debits). The net effect on the current account depends on which component moves most.

Marker's note. Distinguish a multilateral agreement from a bilateral one or a forum, and give a genuine implication with characteristics in (b). In (c) provide clear cause and effect across more than one component of the current account (the balance on goods and services and net primary income), not just exports.

(a) [2 marks]

Cost-push inflation is one cause. When the cost of inputs such as raw materials, energy or wages rises, businesses face higher costs of production and pass these on by raising the prices of their goods and services to protect profit margins, so the general price level rises. (Demand-pull, imported or expectations-driven inflation are equally acceptable.)

(b) [3 marks]

If Australia's inflation rate is higher than that of its trading partners, Australian-made goods and services become relatively more expensive than foreign substitutes. This reduces Australia's international competitiveness: foreign buyers switch away from dearer Australian exports while domestic buyers switch toward cheaper imports. The result is weaker export demand and higher import spending, which worsens the balance on goods and services.

(c) [5 marks]

Labour market policies can either add to or relieve inflation, depending on their type.

Policies that raise wage growth, such as a large rise in the national minimum wage, lift household disposable income and consumer spending. Stronger aggregate demand bids up prices, contributing to demand-pull inflation; higher labour costs also feed cost-push inflation if not matched by productivity.

By contrast, supply-side labour policies such as training, skills and education programs raise labour productivity. Higher output per worker lowers unit labour costs and expands the productive capacity of the economy, easing inflationary pressure. For example, government-funded foundation-skills and apprenticeship programs increase the effective supply of skilled labour, which restrains wage-driven cost pressures over time. So labour market policy is a double-edged tool: wage-setting decisions can be inflationary, while productivity-raising measures are disinflationary.

Marker's note. Use explicit economic concepts and chain them together, for example higher disposable income leads to higher spending leads to demand bidding up prices leads to demand-pull inflation. In (c) cover more than one labour market policy and analyse both the inflationary and the disinflationary channels, with contemporary support.

(a) [2 marks]. Climate change is an environmental issue affecting the Australian economy. The emission of greenhouse gases is warming the climate and increasing the frequency of droughts, bushfires and floods, which damages agricultural output, infrastructure and tourism and imposes adjustment costs on the economy. (Pollution, or the depletion of renewable and non-renewable resources, are equally acceptable.)

(b) [3 marks]. One private benefit is convenience and lower running costs for electric-vehicle owners, who can recharge affordably while shopping without needing home charging infrastructure - a benefit captured directly by the individual user.

One social benefit is a positive externality: more public chargers encourage greater uptake of electric vehicles, which reduces petrol-vehicle emissions and improves local air quality. This benefit spills over to the whole community, not just the driver.

(c) [5 marks]. A market-based policy works by changing prices and incentives rather than by direct regulation. The NSW Return and Earn container deposit scheme is one example: it pays a 10-cent refund for each eligible drink container returned, creating a financial incentive to recycle rather than litter.

It has been effective on several measures. The scheme has collected billions of containers and is associated with a large fall in drink-container litter across NSW, internalising the cost of waste by rewarding recycling. It is also flexible and self-targeting, since only those who recycle receive the payment.

However, its effectiveness is limited. Not all containers are eligible, so some still reach landfill or waterways, and the scheme addresses litter rather than the broader problems of emissions or resource depletion. On balance it is an effective but partial policy: strong for the specific issue of container waste, but narrow in scope. (A carbon price, subsidies for renewables or the National Water Initiative are equally acceptable.)

Marker's note. Keep (a) precise and specific to Australia, not a general global statement. In (b) give one clearly private and one clearly social benefit. In (c) name a genuine market-based policy (not a regulation), support the assessment with data, and weigh strengths against limitations to reach a judgement.

(a) [2 marks]

The international business cycle refers to fluctuations in world output (gross world product) over time, affecting economies globally through trade and finance. A regional business cycle refers to fluctuations shared by a closely integrated group of economies in a geographic area, such as the European Union or ASEAN, whose synchronised trade and financial flows make their cycles move together more tightly than the world as a whole.

(b) [3 marks]

One reason is the difference in income and capital. Advanced economies have high real per capita incomes, which allow high levels of saving and therefore investment in physical and human capital. This accumulation of capital raises productivity and sustains growth - a self-reinforcing source of development that emerging economies, with lower incomes and savings, have historically lacked, leaving them more reliant on foreign capital and aid. (Differences in technology, institutions, natural resources or labour quality are equally acceptable.)

(c) [5 marks]

Economy: China. Globalisation has had contrasting effects on China's economic development.

Integration into the global economy after joining the WTO in 2001 produced rapid export-led growth, with GDP expanding at around 10% a year through the 2000s. This raised national income and government revenue, financing investment in health, education and infrastructure. The results show in development indicators: hundreds of millions lifted out of poverty, rising life expectancy and high adult literacy. Globalisation also brought technology transfer and foreign investment that lifted productivity.

The effects have not all been positive. Reliance on global trade made China vulnerable to external shocks, seen when pandemic-era restrictions on trade and travel sharply slowed growth, interrupting the development gains. Globalisation has also widened the gap between coastal and inland regions and raised environmental costs from rapid industrialisation. On balance, globalisation accelerated China's economic development while increasing its exposure to external volatility and uneven outcomes.

Marker's note. In (a) distinguish a regional cycle from a single domestic economy's cycle. In (c) treat development as a qualitative concept (health, education, literacy as well as GDP), choose a suitable globalising economy, and support the analysis with data rather than describing the country generally.

Band guide

A top-band (17 to 20) response demonstrates a clear and comprehensive understanding of both macroeconomic and microeconomic policy, synthesises the stimulus into a sustained argument, and integrates economic theory, terms and current data. A model answer:

Define the goal

Sustainable economic growth is long-term growth in real GDP that is fast enough to lift living standards and lower unemployment, but not so fast that it triggers inflation or unsustainable external imbalances - growth the RBA frames around its 2 to 3 per cent inflation target (stimulus).

Macroeconomic policy (demand side)

Monetary and fiscal policy are counter-cyclical tools that manage aggregate demand to smooth the business cycle.

• Monetary policy: the RBA sets the target cash rate to influence the cost and availability of credit. Lowering the cash rate stimulates consumption and investment, shifting aggregate demand right; raising it restrains demand when the economy overheats. The stimulus notes that flexible inflation targeting since the 1990s has reduced the variability of output, evidence that monetary policy has supported more sustainable growth.
• Fiscal policy: the federal budget uses government spending and taxation. An expansionary stance (spending up or taxes down) lifts aggregate demand and, via the multiplier, raises national income by more than the initial injection; a contractionary stance restrains an overheating economy. Budget settings also shape resource use and income distribution.

Microeconomic policy (supply side). Microeconomic reform targets individual industries and markets to raise productivity and shift aggregate supply right, allowing growth without inflation. Measures include deregulation, competition policy, tax reform and labour market and skills policy, aiming at allocative, technical and dynamic efficiency. The productivity graph (stimulus) shows labour productivity growth has weakened, especially since around 2017, suggesting microeconomic reform has not delivered the supply-side gains needed and is an area for renewed policy effort.

Discuss the limits and conflicts. No policy is unconstrained. Macroeconomic policy faces time lags (especially fiscal), global influences and political constraints; stimulating growth can conflict with price stability and external balance. Microeconomic reform works slowly and can impose short-term adjustment costs. Sustainable growth therefore requires macroeconomic policy to stabilise demand around the cycle while microeconomic policy lifts the economy's productive capacity, so that demand can grow without reigniting inflation.

Marker's note. Discuss both macroeconomic and microeconomic policy and link macro to aggregate demand and micro to aggregate supply. Use the stimulus actively (the inflation-targeting record and the weakening productivity trend), build in the conflicts and limitations of policy, and define sustainable growth precisely rather than treating it as simply high growth.

Band guide

A top-band (17 to 20) response shows a clear and comprehensive understanding of the policies used to achieve full employment, synthesises the stimulus, and integrates theory and current data. A model answer:

Define the goal

Full employment is the level of unemployment at which there is no cyclical unemployment, leaving only frictional, structural and seasonal unemployment - the non-accelerating-inflation rate of unemployment (NAIRU), below which inflation tends to accelerate. It is measured through the unemployment and participation rates, and underemployment and hidden unemployment matter too. Australian unemployment fell from around 7.5% in 2020 to about 3.5% by 2022, near estimates of full employment.

Macroeconomic policy and cyclical unemployment

Cyclical unemployment moves with the business cycle, so demand-management policy targets it.

• Fiscal policy: expansionary budgets (higher spending or lower taxes) raise aggregate demand and, through the multiplier, increase the derived demand for labour, reducing cyclical unemployment - though this raises questions of revenue, resource allocation and income distribution.
• Monetary policy: cutting the cash rate stimulates spending and investment, lifting employment; the inflation-targeting framework in the stimulus shows the RBA balancing this against price stability.

The trade-off

Pushing unemployment below the NAIRU bids up wages and prices, so there is a short-run trade-off between full employment and price stability (the Phillips curve). Policy aims for the lowest unemployment consistent with stable inflation.

Microeconomic policy and structural unemployment

Structural and frictional unemployment reflect mismatches of skills and location, which demand management cannot fix. Microeconomic policy - training, education and employment programs, labour market deregulation and improved job-matching - raises the skills and mobility of workers. By lifting human capital and productivity (relevant to the weak productivity trend in the stimulus), these supply-side measures reduce the NAIRU itself, allowing lower unemployment without inflation.

Conclusion

Achieving full employment needs both: macroeconomic policy to remove cyclical unemployment by stabilising aggregate demand, and microeconomic policy to attack structural and frictional unemployment by improving the supply and skills of labour, all subject to time lags, global influences and the inflation trade-off.

Marker's note. Define full employment via the NAIRU and distinguish it from simply reducing unemployment. Match cyclical unemployment to short-term macroeconomic policy and structural unemployment to longer-term microeconomic policy, interpret (not restate) the stimulus, and support with current data and the inflation trade-off.

Band guide

A top-band (17 to 20) response demonstrates a clear and comprehensive understanding of the factors driving international economic integration and clearly relates how and why each factor contributes, in a sustained and cohesive response with relevant data and theory. A model answer:

Define the concept

International economic integration is the growing interdependence of economies through cross-border flows of goods, services, finance, labour and technology - the process of globalisation. It is measured through gross world product and the rising share of trade and financial flows in world output.

Trade flows

The growth of global trade in goods and services, faster than world output for decades, has tied economies together through specialisation and comparative advantage. Trade liberalisation - free trade agreements, customs unions and trading blocs such as the EU and ASEAN, and reduced tariffs under the WTO - has been a key driver, while protectionist policies work in the opposite direction by reducing integration.

Financial flows and investment

The deregulation of capital markets has produced large global financial flows and foreign direct investment, much of it channelled through transnational corporations that build global supply chains. These flows integrate national financial systems, so that shocks and business cycles increasingly synchronise across economies and regions.

Technology, transport and labour

Advances in transport (containerisation) and communication technology (the internet, instant global payments) have sharply lowered the cost of trading and coordinating across borders, enabling the international division of labour. Migration flows move labour to where it is most productive, deepening integration further.

International organisations and forums

Institutions such as the WTO (trade rules), the IMF and World Bank (financial stability and development finance), and forums such as the G20 coordinate policy, set common rules and resolve disputes, reducing the frictions to cross-border activity and reinforcing integration.

Conclusion

These factors reinforce one another: liberalised trade and finance, falling transport and communication costs, mobile labour and capital, and coordinating institutions have together driven the long-run rise in international economic integration, while protection and crises can slow or partially reverse it.

Marker's note. Do not just list the factors - show how and why each one contributes to integration. Cover trade and financial flows, technology and the international division of labour, trade agreements and the removal of protection, and the role of international organisations, with trends and data.

Band guide

A top-band (17 to 20) response shows a clear and comprehensive understanding of how an appreciation affects all three groups, drawing out the relationships with relevant theory, terms and data in a sustained response. A model answer:

Define the movement

An appreciation is a rise in the value of the Australian dollar against other currencies (a rise in the Trade Weighted Index), raising its purchasing power over foreign goods, services and assets. It can be driven by higher Australian interest rates, a rise in the terms of trade or stronger demand for Australian assets.

Impacts on individuals

A stronger dollar makes imports cheaper, so households gain greater purchasing power over imported goods, overseas travel and online purchases, lifting real incomes and living standards and easing inflationary pressure. The offsetting risk is to jobs: workers in export and import-competing industries (such as manufacturing and tourism) may face reduced demand and lower employment as those industries lose competitiveness.

Impacts on firms

The effect differs by firm type. Importing firms and those using imported inputs benefit, as inputs and capital goods become cheaper, lowering costs. Exporting firms are worse off: their goods become dearer in foreign-currency terms, reducing international competitiveness and export demand, output and revenue. Import-competing firms also lose, as cheaper imports undercut them domestically. Over time this can drive structural change, and prolonged appreciation from a resources boom can crowd out other trade-exposed sectors (Dutch disease).

Impacts on government

A weaker export sector reduces output, employment and therefore company and income tax revenue, and may increase welfare spending - a budgetary cost. The appreciation also worsens the balance on goods and services as exports fall and imports rise. There are offsets: the Australian-dollar cost of servicing foreign debt denominated in foreign currency falls, easing the government's debt-servicing burden, and lower imported inflation gives the RBA more room for expansionary monetary policy. Weaker growth from reduced export demand may prompt the government toward a more expansionary macroeconomic stance.

Conclusion

An appreciation benefits individuals and importing firms through cheaper imports and lower inflation, but harms exporters, import-competing firms and, through them, government revenue and the external balance. The net impact depends on the size and persistence of the movement and the structure of the economy.

Marker's note. Make sure you analyse an appreciation (not a depreciation), and cover all three groups - individuals, firms and government - drawing out the relationship between the currency movement and each impact. Integrate relevant theory (the reverse J-curve, Dutch disease) and, where possible, a correctly labelled diagram and current data.
