Discretionary Stabilisers and Aggregate Demand

Overview of Discretionary Fiscal Policy

• Definition: Deliberate changes in government spending (G) and taxation (T) to influence aggregate demand (AD) and stabilise the business cycle. These are active policy choices.
• Contrast with Automatic Stabilisers: Unlike automatic stabilisers (e.g., unemployment benefits), discretionary stabilisers require explicit government action and legislative approval.
• Role in Influencing AD: Discretionary fiscal policy aims to shift the AD curve to achieve macroeconomic goals.
• Structural Component of the Budget: Discretionary fiscal policy is associated with the structural component of the budget, reflecting deliberate policy choices.

KEY TAKEAWAY: Discretionary stabilisers are active government policies designed to influence AD, while automatic stabilisers are passive responses to economic fluctuations.

Mechanisms of Discretionary Stabilisers

1. Changes in Government Spending (G)

• Expansionary Fiscal Policy (Stimulus):
  • Increase in government spending on infrastructure projects, education, healthcare, etc.
  • Aims to directly increase AD.
  • Example: Government invests in building new roads and bridges.
• Contractionary Fiscal Policy (Austerity):
  • Decrease in government spending to reduce AD and control inflation.
  • Example: Government cuts funding for certain public programs.

2. Changes in Taxation (T)

• Expansionary Fiscal Policy:
  • Reduction in personal income tax rates to increase disposable income and consumption (C).
  • Reduction in company tax rates to encourage investment (I).
  • Example: Government reduces the company tax rate from 30% to 25%.
• Contractionary Fiscal Policy:
  • Increase in personal income tax rates to reduce disposable income and consumption.
  • Increase in company tax rates to decrease investment.
  • Example: Government increases the GST rate.

Impact on Aggregate Demand (AD)

• Expansionary Fiscal Policy: Shifts the AD curve to the right.
  • Increases real GDP.
  • Reduces unemployment.
  • May lead to higher inflation.
• Contractionary Fiscal Policy: Shifts the AD curve to the left.
  • Decreases real GDP.
  • Increases unemployment.
  • Reduces inflation.

Stabilising the Business Cycle

• Counter-Cyclical Policy: Discretionary fiscal policy is often used counter-cyclically to smooth out fluctuations in the business cycle.

  Phase of Business Cycle	Policy Response	Impact on AD
  Recession	Expansionary Fiscal Policy	Increase AD
  Boom	Contractionary Fiscal Policy	Decrease AD
  * Recession: During a recession, the government may implement expansionary fiscal policy to stimulate economic activity. This helps to increase AD and reduce unemployment.
  * Boom: During an economic boom, the government may implement contractionary fiscal policy to cool down the economy and prevent excessive inflation. This helps to decrease AD and maintain price stability.

EXAM TIP: When discussing the impact of discretionary fiscal policy, always link the policy change to its effect on AD and the broader macroeconomic goals (economic growth, full employment, and low inflation).

Examples of Discretionary Fiscal Policy

• Economic Stimulus Packages: Governments may introduce large-scale stimulus packages during economic downturns, including tax cuts and infrastructure spending.
• Targeted Spending Programs: Specific programs aimed at supporting particular industries or regions affected by economic shocks.
• Changes in Welfare Payments: Adjusting the level of welfare payments to support vulnerable households during economic hardship.

Strengths and Weaknesses of Discretionary Fiscal Policy

Strengths

• Targeted: Can be targeted at specific sectors or regions of the economy.
• Direct Impact: Government spending directly increases AD.
• Multiplier Effect: Initial changes in government spending or taxation can have a larger impact on AD due to the multiplier effect.

Weaknesses

• Time Lags:
  • Recognition Lag: It takes time to recognise that the economy is in a recession or boom.
  • Decision Lag: It takes time for the government to decide on and implement a policy response.
  • Impact Lag: It takes time for the policy to have its full effect on the economy.
• Political Constraints: Political considerations may influence policy decisions.
• Crowding Out: Government borrowing to finance increased spending may lead to higher interest rates, crowding out private investment.
• Budget Deficits and Debt: Expansionary fiscal policy can lead to budget deficits and increased government debt.

COMMON MISTAKE: Confusing discretionary fiscal policy with monetary policy. Fiscal policy is implemented by the government, while monetary policy is implemented by the Reserve Bank of Australia (RBA).

Relationship to Budget Outcomes and Government Debt

• Budget Outcome: Discretionary fiscal policy affects the budget outcome (surplus, deficit, or balanced budget).
  • Expansionary fiscal policy typically leads to a budget deficit.
  • Contractionary fiscal policy typically leads to a budget surplus.
• Government Debt: Persistent budget deficits can lead to an accumulation of government debt.
• Sustainability: Governments need to consider the sustainability of their fiscal policies and the impact on future generations.

STUDY HINT: Create a table summarising the different types of discretionary fiscal policies, their intended effects on AD, and their potential impacts on the budget outcome and government debt.

Recent Examples in Australia

• COVID-19 Pandemic Response: The Australian government implemented a range of discretionary fiscal measures to support the economy during the COVID-19 pandemic, including JobKeeper and increased welfare payments.
• Infrastructure Spending: Ongoing investment in infrastructure projects to stimulate economic growth and improve productivity.
• Tax Cuts: Changes to personal and company tax rates to encourage spending and investment.

Conclusion

Discretionary fiscal policy plays a crucial role in influencing aggregate demand and stabilising the business cycle. While it can be an effective tool for managing the economy, it is important to consider the potential strengths and weaknesses, including time lags, political constraints, and the impact on budget outcomes and government debt.

VCAA FOCUS: Be prepared to analyse the effectiveness of specific discretionary fiscal policies in achieving macroeconomic goals, considering both the potential benefits and drawbacks.
