Explain microeconomic reform and supply-side policy, how it raises productivity and aggregate supply, and evaluate examples in the Australian economy

What this dot point is asking

SCSA wants you to define microeconomic reform, explain how supply-side policy raises productivity and aggregate supply, and evaluate Australian examples. Expect a long-run AS diagram and an extended response on the role of reform versus demand management.

What microeconomic reform is

Whereas fiscal and monetary policy manage aggregate demand, microeconomic reform is supply-side: it targets the productive capacity of the economy. By raising productivity, it lifts potential output, shifting the long-run aggregate supply (LRAS) curve to the right. On the AD/AS diagram, this allows higher real GDP at a lower price level over time.

How it raises productivity and aggregate supply

Reform raises productivity (output per unit of input) by:

• Increasing competition, which forces firms to cut costs and innovate.
• Removing regulatory barriers that misallocate resources.
• Improving the quality of labour and capital through skills and investment.
• Lowering input costs across the economy.

Higher productivity reduces unit costs, which both lifts AS and improves international competitiveness. It is the main long-run driver of real wages and living standards.

Main areas of reform

• Trade liberalisation: cutting tariffs and protection to expose industries to competition (covered in Unit 3).
• Labour market reform: the move from centralised wage fixing to enterprise bargaining and a more flexible system, balancing flexibility against fairness.
• Competition policy: the National Competition Policy of the 1990s and the work of the ACCC to promote competition and deter anti-competitive conduct.
• Deregulation and privatisation: floating the dollar (1983), deregulating financial markets, and privatising government businesses such as Qantas, the Commonwealth Bank and Telstra to improve efficiency.
• Tax reform: broadening the base and improving incentives, for example the introduction of the GST in 2000.
• Infrastructure, skills and innovation: investment in transport, energy, education and research to raise capacity.

Strengths of microeconomic reform

• Raises long-run growth without adding to inflation, by expanding capacity.
• Improves international competitiveness by lowering unit costs.
• Lifts real wages and living standards through higher productivity.
• Complements macroeconomic policy: a larger productive capacity eases the inflation-growth trade-off.

Weaknesses and costs

• Long time lags: the benefits take years to appear, unlike monetary or fiscal policy.
• Structural adjustment costs: reform creates losers, such as workers in protected or privatised industries, requiring transitional support.
• Political difficulty: concentrated losses and dispersed gains make reform hard to legislate.
• Equity concerns: efficiency gains may not be shared evenly, and some reforms (such as labour market deregulation) raise distributional questions.
