Supply-Side Policy (Copy)

4.5.1 Definition of Supply-side Policy

• Supply-side policy:
  • Government strategies aimed at increasing the productive capacity (aggregate supply) of the economy.
  • Focuses on improving efficiency and competitiveness rather than boosting demand.
  • Long-term approach → encourages sustainable growth, lower unemployment, and price stability.
• Aim:
  • Shift the economy’s production possibility frontier (PPF) outward.
  • Increase potential GDP.
  • Improve supply conditions so firms can produce more at lower cost.

Aggregate Supply ↑ → More Output, Lower Prices
      PPF shifts outward

4.5.2 Supply-side Policy Measures

Education and Training

• Improves skills, productivity, and employability of workers.
• Higher productivity → lower unit costs → greater competitiveness.
• Long-term solution to structural unemployment.

Diagram:

Better Training → Productivity ↑ → Output ↑

Labour Market Reforms

• Reduce rigidities in hiring and firing.
• Encourage flexible contracts and mobility of labour.
• Remove minimum wage restrictions (in some cases) to boost employment.
• Increases efficiency of labour allocation.

Lower Direct Taxes (on income and profits)

• Reduces disincentives to work and invest.
• Higher disposable income → encourages labour participation.
• Firms retain more profits → reinvest in expansion.

Diagram:

Lower Taxes → More Work + More Investment → Growth ↑

Deregulation

• Reduction of government rules and restrictions on businesses.
• Encourages competition, efficiency, and innovation.
• Leads to lower prices and more consumer choice.

Improving Incentives to Work and Invest

• Policies to encourage entrepreneurship.
• Subsidies for research and development (R&D).
• Reward risk-taking and innovation.
• Improve labour market participation (childcare support, welfare reforms).

Privatisation

• Transfer of state-owned enterprises to private sector.
• Belief: private firms are more efficient due to profit motive.
• Improves quality of services and reduces government financial burden.

Privatisation → Efficiency ↑ → Costs ↓ → Output ↑

4.5.3 Effects of Supply-side Policy Measures on Government Macroeconomic Aims

1. Economic Growth

• Successful supply-side policies expand productive capacity.
• Shift long-run aggregate supply (LRAS) to the right.
• Allows sustainable growth without causing inflation.

Supply-side Policy → LRAS shifts right → Growth ↑

2. Employment

• Education and training reduce structural unemployment.
• Labour market reforms encourage firms to hire.
• Lower taxes → more willingness to work.
• Overall → reduces both frictional and structural unemployment.

3. Stable Prices (Low Inflation)

• By reducing production costs, supply-side policies lower inflationary pressures.
• Long-term control of cost-push inflation.
• Ensures price stability without reducing growth.

4. Balance of Payments Stability

• Improved efficiency and competitiveness → exports increase.
• Lower production costs → domestic goods more competitive abroad.
• Reduces trade deficits and improves balance of payments.

5. Redistribution of Income

• Mixed effect:
  • Lower taxes may benefit higher earners more.
  • Training/education helps low-skilled workers improve earnings.
• Not the main aim of supply-side policy, but can indirectly reduce inequality.
