Fiscal policy is the use of government revenue and expenditure to influence economic activity and achieve macroeconomic objectives. In Australia, the federal budget is the main fiscal policy instrument. It affects aggregate demand directly through government spending and indirectly through household disposable income, business costs and confidence.

The central fiscal question is not simply whether the budget is in deficit or surplus. The question is whether the fiscal stance is appropriate for the economy's position in the cycle and for long-run sustainability.

Government sector roles

The government sector has three major roles in macroeconomic management.

| Role | What government does | Economics link | |---|---|---| | Reallocation of resources | Uses taxes, subsidies, regulation and spending to shift resources toward or away from particular uses | Can address market failure and influence allocative efficiency. | | Redistribution of income | Uses progressive taxation, transfer payments and public services to change the distribution of income and opportunity | Can improve equity, but may affect incentives. | | Macroeconomic stabilisation | Uses fiscal policy to influence aggregate demand across the business cycle | Can reduce recessions, inflationary booms and unemployment volatility. |

Fiscal policy, monetary policy and microeconomic policy are complementary. Fiscal and monetary policy mainly work on the demand side in the short run, while microeconomic and supply-side policies mainly work on productive capacity in the long run.

Revenue

Government revenue mainly comes from taxation.

| Revenue source | Meaning | Economic effect | |---|---|---| | Direct tax | Paid directly by households or firms, such as income tax and company tax | Changes disposable income, saving, work incentives and investment returns. | | Indirect tax | Paid through transactions, such as GST or excise | Changes prices and purchasing power. | | Progressive tax | Average tax rate rises as income rises | Supports equity and automatic stabilisation. | | Proportional tax | Same average tax rate for all incomes | Revenue rises proportionally with income. | | Regressive tax | Lower-income earners pay a higher share of income | Can worsen equity even if administratively simple. |

Tax cuts can be expansionary because households and firms retain more income. Tax increases can be contractionary because they reduce disposable income and spending.

Expenditure

Government expenditure includes current spending, capital spending and transfer payments.

| Expenditure type | Meaning | Example | |---|---|---| | Current expenditure | Ongoing spending on goods and services | public-sector wages, health services, education | | Capital expenditure | Spending on long-lived assets | transport infrastructure, hospitals, defence equipment | | Transfer payments | Payments that redistribute income rather than buy current output | pensions, unemployment benefits, family payments | | Public utilities and merit goods | Goods or services government provides or supports due to public benefit | roads, public transport, schooling, vaccination |

Spending on infrastructure can affect both aggregate demand and aggregate supply. In the short run, it raises demand through construction and employment. In the long run, it may improve productivity if it reduces transport costs or expands capacity.

Expansionary and contractionary fiscal policy

Expansionary fiscal policy increases aggregate demand. It may include higher government expenditure, lower taxation, or larger transfer payments. It is usually used when growth is weak and unemployment is rising.

Contractionary fiscal policy reduces aggregate demand. It may include lower expenditure, higher taxation, or reduced transfer payments. It is usually used when inflation is too high, the economy is overheating or public debt sustainability is a concern.

Inflationary gaps and deflationary gaps help explain the stance. An inflationary gap occurs when actual output is above sustainable potential output, creating upward price pressure. A deflationary gap occurs when actual output is below potential output, creating spare capacity and unemployment.

Automatic stabilisers and discretionary policy

Automatic stabilisers work without new policy decisions. In a downturn, tax receipts fall and welfare payments rise, softening the fall in aggregate demand. In a boom, tax receipts rise and welfare spending falls, slowing demand growth.

Discretionary fiscal policy is a deliberate change to spending or taxation. It can be targeted, but it faces time lags: recognition lag, decision lag, implementation lag and impact lag.

Non-discretionary fiscal policy is the automatic part of the budget. Progressive income tax is a key example. During a boom, incomes rise and more income is taxed at higher marginal rates, automatically withdrawing demand. During a downturn, incomes fall and tax receipts fall, helping households retain more income. Welfare payments also respond automatically: unemployment benefits tend to rise in downturns and fall in expansions.

Discretionary fiscal policy is more deliberate. Examples include a temporary investment allowance, a new infrastructure project, a change in income-tax thresholds, a cost-of-living payment or a targeted industry support package. The advantage is targeting; the weakness is delay and political negotiation.

Crowding out

Crowding out occurs when government borrowing contributes to higher interest rates or absorbs financial resources that might otherwise fund private investment. If private investment falls, the expansionary effect of a deficit can be partly offset.

Crowding out is more likely when the economy is near full capacity and the government competes with private borrowers for scarce savings. It is less likely during a downturn if there is spare capacity and weak private investment demand.

Funding deficits and using surpluses

A deficit must be financed. The method matters because it affects future costs and the wider economy.

| Method | How it works | Main issue | |---|---|---| | Borrowing from the private sector | The government sells securities to households, firms or financial institutions | Can create interest obligations and may crowd out private investment if financial resources are scarce. | | Borrowing from overseas | Foreign investors buy government securities | Can increase income payments overseas and exposure to external confidence. | | Monetary financing | The central bank creates money to finance spending | Can be inflationary and is not a normal Australian budget practice. |

A surplus can be used to repay debt, build fiscal buffers, fund future investment or reduce pressure on inflation. However, a surplus also withdraws spending from the circular flow. In a weak economy, that may deepen a downturn unless private demand or exports are strong enough to offset it.

Recent fiscal examples

Historical examples help when evaluating policy.

| Period | Fiscal lesson | |---|---| | Early 2000s resources boom | Strong incomes and company profits can lift tax receipts and move the budget toward surplus through automatic stabilisers. | | Global Financial Crisis | Discretionary stimulus can support aggregate demand when private spending and confidence collapse. | | Mid-2010s consolidation attempts | Governments may try to reduce deficits to rebuild fiscal space, but spending commitments and weak revenue can make consolidation difficult. | | COVID-19 shutdowns | Very large discretionary support can protect employment and incomes during an artificial collapse in activity, but it increases deficits and debt. | | High-inflation periods | Fiscal restraint can support monetary policy by avoiding extra demand pressure. Poorly targeted spending can make inflation harder to reduce. |

Use these as patterns rather than memorised history. The exam skill is explaining why a stance was appropriate or inappropriate for the conditions shown in the stimulus.

Evaluating fiscal effectiveness

| Strength | Limitation | |---|---| | Can be targeted to regions, industries or households | Political negotiation can delay action. | | Direct government spending has an immediate AD component once implemented | Projects can have long planning and construction lags. | | Transfer payments can support lower-income households with high MPC | Poorly targeted transfers can increase inflation without raising productive capacity. | | Infrastructure can improve long-run supply | Deficits may increase public debt and interest costs. |

Fiscal policy must also be judged by equity. A tax cut may stimulate demand, but the distribution of benefits matters. A spending cut may improve the budget balance, but it may reduce services relied on by vulnerable groups.
