Unit 4: Economic Policy and Management - Objectives, Instruments and Evaluation
Core concepts to master
Unit 4 focuses on how governments pursue macroeconomic objectives: strong and sustainable growth, full employment, price stability (low inflation), a sustainable external position, and equitable distribution of income. You must know the policy instruments: fiscal policy (government spending and taxation, automatic stabilisers versus discretionary measures), monetary policy (the cash rate set by the Reserve Bank of Australia, transmission mechanism), and supply-side policies (microeconomic reform, education, infrastructure, competition policy). Understand the business cycle, the output gap, and how policy responses differ in booms versus downturns. Know the Phillips curve trade-off and the concept of the non-accelerating inflation rate of unemployment (NAIRU). Be able to evaluate policy using criteria: effectiveness, timeliness, flexibility, and unintended consequences.
Traps examiners set
- Confusing contractionary fiscal policy (higher taxes, lower spending) with expansionary policy.
- Assuming monetary policy alone can fix structural unemployment - supply-side policy is needed.
- Forgetting lags: recognition, decision and implementation lags weaken discretionary fiscal policy.
- Treating inflation targeting as a rigid rule rather than a flexible framework with a 2–3% target band.
Worked rule of thumb
For any policy question, use the PEME scaffold: Policy identified and mechanism explained; Effect on the objective (with direction and magnitude); Multiplier or transmission channel; Evaluation (limitations, trade-offs, time lags). Example: an increase in the cash rate raises borrowing costs, reducing consumption and investment, lowering aggregate demand and inflationary pressure - but with a lag of several quarters and uneven effects across indebted households.
