What is the AD/AS framework?Show answer
Aggregate demand (AD) is the total demand for goods and services in the economy at each price level. AD = C + I + G + (X - M).
What is factors that affect aggregate demand?Show answer
1. Consumer confidence. Measured by the Westpac-Melbourne Institute Consumer Sentiment Index. Higher confidence raises consumption (C), shifting AD right.
What is factors that affect aggregate supply?Show answer
AS factors operate on the productive capacity of the economy.
What is cause-and-effect chains?Show answer
The VCE answer style requires explicit cause-and-effect chains. Examples:
What is application to current Australian conditions (2024-25)?Show answer
Net: AD restraint by tight monetary policy is bringing inflation down; AS expansion by migration and reform is gradually raising LRAS.
What is limits of the framework?Show answer
1. Stickiness. Prices and wages adjust with lags, so the textbook AD/AS framework gives the long-run direction but not the short-run path.
What is 1. Consumer confidence?Show answer
Measured by the Westpac-Melbourne Institute Consumer Sentiment Index. Higher confidence raises consumption (C), shifting AD right.
What is recent Australian example?Show answer
Consumer sentiment fell to recession-era lows during the 2022-23 RBA tightening cycle, weighing on retail spending. It has recovered modestly in 2024-25 as inflation has eased.
What is 2. Business confidence?Show answer
Measured by the NAB Business Confidence Index. Higher confidence raises investment (I).
What is 3. Interest rates?Show answer
The cash rate flows through to mortgage, business loan and deposit rates. Higher rates: - Reduce mortgage holder disposable income (mortgage repayments rise). - Make borrowing-financed consumption and investment more expensive.
What is 4. Disposable income?Show answer
After-tax household income. Driven by: - Wages and salaries (the Wage Price Index). - Income tax (Stage 3 cuts from 1 July 2024 raised real disposable income by around 1 percent of GDP).
What is 5. The exchange rate?Show answer
AUD movements affect net exports (X - M): - AUD depreciation raises export competitiveness and makes imports more expensive, supporting AD. - AUD appreciation has the opposite effect.
What is 6. Government economic activity?Show answer
Federal, state and local government spending (G). The 2020-21 COVID-19 stimulus was the largest fiscal expansion in Australian peacetime history. The 2024-25 Budget tightened the structural position.
What is 7. Overseas economic conditions?Show answer
Demand from trading partners. Australia's exports are sensitive to: - Chinese GDP growth (32 percent of exports). - Japanese, South Korean and ASEAN demand (combined around 35 percent).
What is 8. Population growth?Show answer
Higher population (driven by net overseas migration around 500,000 in 2023-24) raises consumption and housing demand, shifting AD right.
