ACT SSC Economics — Unit 4
Monetary Policy — Flashcards & Quiz
Monetary policy is the RBA's use of the cash rate to influence inflation, unemployment and growth. For ACT SSC Economics Unit 4 you need to describe the RBA's 2-3% inflation target, explain the transmission mechanism from cash rate to aggregate demand, and evaluate monetary policy against its trade-offs and lags. Anchor your discussion in recent RBA decisions and CPI outcomes.
Key Points
- RBA targets 2-3% inflation over the cycle, using the cash rate as the main instrument.
- Cash rate set at Reserve Bank Board meetings and transmitted through bank lending and deposit rates.
- Transmission channels: interest rates (spending, investment), exchange rate, asset prices, expectations, credit.
- Expansionary (rate cut) stimulates AD; contractionary (rate rise) cools AD and inflation.
- Strengths: quick implementation, independent of politics, forward-looking. Weaknesses: impact lags 6-18 months, blunt tool.
- Zero lower bound: when rates near zero, unconventional tools (QE, forward guidance) are used.
Common Mistakes to Avoid
- Confusing monetary policy (cash rate) with fiscal policy (budget).
- Claiming rate changes work instantly — transmission typically lags 6-18 months.
- Ignoring the exchange rate channel — lower rates usually depreciate the AUD.
- Forgetting the RBA's dual focus on inflation and full employment.
- Treating monetary policy as the only tool — it works best alongside fiscal policy and structural reform.
Exam Strategy
ACT SSC Unit 4 monetary policy questions typically ask you to evaluate an RBA decision or compare monetary with fiscal policy. Method: (1) state the current economic context (inflation, unemployment, output gap), (2) describe the policy action and its stance, (3) trace the transmission channels, (4) evaluate strengths, weaknesses and lags, (5) compare with fiscal policy and conclude on the policy mix. Cite recent RBA statements for top marks.
Sample Flashcards
Q1: What are the objectives of the RBA’s monetary policy?
The RBA has three objectives: 1) Stability of the Australian currency (low inflation of 2–3%). 2) Maintenance of full employment. 3) Economic prosperity and welfare of the Australian people. These are set out in the Reserve Bank Act 1959.
Q2: Explain the transmission mechanism of monetary policy.
The RBA adjusts the cash rate → commercial banks adjust lending/deposit rates → this affects borrowing and saving decisions → which changes consumption (C) and investment (I) → shifting aggregate demand → influencing economic growth, employment and inflation.
Q3: What are the limitations of monetary policy?
Limitations include: time lags (12–18 months for full effect), blunt instrument (affects all sectors equally), ineffective at near-zero rates (liquidity trap), cannot address supply-side issues (cost-push inflation), and the exchange rate channel can harm exporters.

Q3: Monetary policy takes effect immediately with no time lags.
Answer: FALSE
Monetary policy has significant time lags of 12–18 months for the full effect to flow through the economy.
