Expansionary and contractionary fiscal policy

Fiscal policy involves government adjustments to spending and taxation to influence the economy. It can be used to manage aggregate demand, which is the total demand for goods and services in an economy.

Expansionary fiscal policy

Expansionary fiscal policy aims to boost aggregate demand by increasing government spending or reducing tax rates or the tax base. This creates a net injection into the circular flow of income, often by enlarging an existing budget deficit.

Contractionary fiscal policy

Contractionary fiscal policy seeks to slow the growth of aggregate demand through cuts in government spending or increases in taxes. It may result in a budget surplus, where government income exceeds expenditure.

Discretionary fiscal policy and automatic stabilisers

Fiscal policy can be implemented through deliberate government actions or through built-in mechanisms that adjust automatically to economic conditions.

Discretionary fiscal policy

Discretionary fiscal policy involves intentional changes in government spending and taxation based on specific policy decisions. These adjustments are made to address particular economic issues, such as altering tax rates or launching new spending programmes.

Automatic stabilisers

Automatic stabilisers are elements of government spending and taxation that adjust without direct intervention to counteract fluctuations in gross domestic product (GDP).

During economic downturns:

• Government spending on social security benefits rises automatically as more people qualify for support due to job losses.
• Tax revenues from corporate tax, income tax, and indirect taxes decrease naturally as profits, incomes, and overall spending fall.

During periods of economic growth:

• Benefit payments decline as employment rises and fewer people need support.
• Tax revenues increase with higher incomes, profits, and expenditure.

Applications and limitations of contractionary fiscal policy

Contractionary fiscal policy is applied in specific scenarios to manage economic pressures, but it comes with potential drawbacks.

Applications of contractionary fiscal policy

• Combating demand-pull inflation - Reduces excess aggregate demand that drives up prices.
• Tax adjustments - Involves raising tax rates, lowering thresholds, or widening the tax base to increase revenue.
• Spending reductions - Cuts in government expenditure to lower overall demand.
• Use in certain economies - Particularly useful where tax collection systems are underdeveloped, as spending cuts may be easier to implement.

Limitations of contractionary fiscal policy

• Wage demands and inflation risks - Higher income taxes may prompt workers to seek wage rises to preserve disposable income; if granted, this increases firms' costs and could lead to cost-push inflation.
• Disincentive effects - Elevated taxes might discourage work or investment, reducing motivation.
• Labour market impacts - Some workers may leave the workforce or move to areas with lower taxes.
• Effect on aggregate supply - Can diminish the economy's productive capacity by limiting resources available for growth.

Applications and limitations of expansionary fiscal policy

Expansionary fiscal policy is used to revive economic activity, though its success depends on various factors.

Applications of expansionary fiscal policy

• Stimulating growth in recessions - Increases aggregate demand to encourage recovery.
• Tackling cyclical unemployment - Addresses job losses linked to low demand during economic downturns.
• Tax reductions - Lowers taxes to enhance consumer spending and business investment.
• Increased government spending - Direct injections through projects like infrastructure, which boost demand and create jobs.

Limitations of expansionary fiscal policy

• Low confidence issues - If consumers and businesses lack optimism, they may save extra income rather than spend it, weakening the policy's impact.
• Risk of inflation - Excessive stimulus can overheat the economy, leading to demand-pull inflation where demand outstrips supply.
