HSC Economics practice questions for 2026: all four topics

Question 11: "Distinguish between demand-pull and cost-push inflation, giving one Australian example of each from the 2022 to 2024 period." (5 marks)

Demand-pull inflation occurs when aggregate demand grows faster than aggregate supply, so buyers bid up the prices of goods and services that the economy cannot supply fast enough. In Australia in 2022, pandemic-era fiscal and monetary stimulus and pent-up consumer demand pushed spending up while supply remained constrained, contributing demand-pull pressure as the economy ran near full capacity (unemployment near 3.5 percent). Cost-push inflation occurs when rising input costs (wages, energy, imported materials) push firms' costs up, and they raise prices to protect margins, shifting aggregate supply left. In 2022 the war in Ukraine drove up global energy prices and supply-chain disruption raised the cost of imported goods, a clear cost-push (and partly imported) source of the 7.8 percent headline CPI peak in the December 2022 quarter. The key distinction is the source: demand-pull comes from the demand side (too much spending), cost-push from the supply side (rising costs).

Prompt (question 17): "Discuss the effectiveness of the policy mix (fiscal, monetary and microeconomic policy) in managing the Australian economy." (20 marks, 35 minutes)

Minutes 0-4, plan. Thesis: the policy mix is most effective when demand-side and supply-side policies are coordinated, as in the 2022 to 2024 disinflation, but each policy has limits that justify using them together. Four paragraph topics: (a) monetary policy and the 2022 to 2024 tightening; (b) fiscal policy and the contractionary Budget stance; (c) microeconomic and labour market reform on the supply side; (d) coordination and the conflicts between objectives. Diagrams: AD/AS and the Phillips curve. Data: cash rate 4.35 percent (November 2023), CPI peak 7.8 percent (December 2022 quarter), unemployment 3.5 to 4.1 percent, Budget surpluses 2022-23 and 2023-24.

Minutes 4-8, introduction. Define the policy mix. State the thesis. Signpost the four paragraphs.

Minutes 8-30, body. Four paragraphs of roughly 200 to 220 words. Each opens with a topic sentence, runs theory plus a diagram reference plus a specific figure, and closes by returning to "discuss the effectiveness."

Minutes 30-34, conclusion. Restate the thesis; give a qualified judgement (effective but not costless); name the main limitation (the transmission lag and uneven incidence of monetary policy).

Minutes 34-35, review. Check the thesis appears in the introduction and conclusion, that each paragraph cites a figure, and that at least one diagram is described.

Prompt (question 15): "Analyse the effectiveness of monetary policy in achieving the objectives of low inflation and full employment in Australia between 2022 and 2024." (20 marks)

Thesis: monetary policy was largely effective in restoring low inflation while keeping employment close to full, achieving much of the RBA's "narrow path," though at a cost to indebted households and per-capita growth. Paragraph 1 (low inflation): the cash rate rose from 0.10 percent (May 2022) to 4.35 percent (November 2023), the fastest tightening in three decades; through the interest rate channel this cut consumption and shifted aggregate demand left (AD/AS diagram), and headline CPI fell from 7.8 percent (December 2022 quarter) toward 3 percent by early 2025. Paragraph 2 (full employment): despite the tightening, unemployment rose only modestly from 3.5 percent to 4.1 percent, close to the estimated NAIRU of 4 to 4.5 percent, so the disinflation was achieved without a large rise in cyclical unemployment; on the Phillips curve, the economy moved up toward the NAIRU rather than into a recession. Paragraph 3 (limits): the 12 to 18 month transmission lag forced the RBA to forecast inflation; the burden fell unevenly on recent mortgage holders; and the disinflation was slower than first forecast, raising the risk of over-tightening. Conclusion: monetary policy was effective but blunt, which is why it worked best alongside a contractionary Budget and supply-side measures.

The policy mix is the combination of fiscal, monetary, microeconomic, labour market and environmental policy that governments use together to pursue the objectives of economic management. A demand-side example is monetary policy (changing the cash rate to manage aggregate demand). A supply-side example is microeconomic reform (such as tariff cuts) to lift aggregate supply and productive capacity.

Five figures: cash rate (4.35 percent peak, November 2023, in percent per annum); headline CPI (7.8 percent peak, December 2022 quarter, annual percentage change); the unemployment rate (around 3.5 to 4.1 percent, percent of the labour force); real GDP growth (trend around 2.25 to 2.5 percent per year); and the current account balance (as a percentage of GDP). The trimmed mean, the AUD/USD rate and the underlying cash balance are also worth carrying. Always note the source and the date.

A flow is measured over a period of time; a stock is measured at a point in time. Income is a flow (the wages, profits and transfers a household receives over, say, a year). Wealth is a stock (the value of the assets a household owns less its liabilities at a given date). A household can have high wealth but low current income, such as an asset-rich retiree, which is why the two must be distinguished when discussing inequality.

5

For "evaluate the extent to which strong growth, low inflation and external stability conflict, and how the government manages these conflicts": (a) growth versus inflation (the Phillips-curve trade-off, managed by monetary policy near the NAIRU); (b) growth versus external stability (faster growth widens the current account deficit, managed by supply-side competitiveness reform); (c) the role of the policy mix in balancing these objectives (the 2022 to 2024 coordination); (d) a judgement on the extent of conflict (real in the short run, eased by supply-side reform in the long run).

An interest rate rise: the AD/AS diagram (aggregate demand shifts left). The trade-off between inflation and unemployment: the Phillips curve. Income inequality: the Lorenz curve (with the Gini coefficient as the summary statistic).
