A contractionary fiscal policy can shift aggregate demand down from AD 0 to AD 1, leading to a new equilibrium output E 1, which occurs at potential GDP. Again, the AD–AS model does not dictate how this contractionary fiscal policy is to be carried out.

In order to understand how monetary and fiscal policy affect aggregate demand (AD), it's important to know how it's calculated: AD=C+I+G+(X−M)where:C=Consumer spending on goods and servicesI=Investment spending on business capital goodsG=Government spending on public goods and servicesX=ExportsM=Imports\begin{aligned} &AD = C + I + G + (X - M)\\ &\...
Fiscal policy determines government spending and tax rates. Expansionary fiscal policy, usually enacted in response to recessions or employment shocks, increases government spending in areas such as infrastructure, education, and unemployment benefits. According to Keynesian economics, these programs can prevent a negative shift in aggregate demand...
Monetary policy is enacted by central banks by manipulating the money supply in an economy. The money supply influences interest rates and inflation, both of which are major determinants of employment, cost of debt, and consumption levels. Expansionary monetary policy involves a central bank buying Treasury notes, decreasing interest rates on loans...
Aggregate demand is a measure of total demand, which includes consumer spending on goods and services, investment spending on business capital goods, government spending on public goods and services, exports, and imports. Both fiscal and monetary policy affect aggregate demand. Fiscal policy impacts aggregate demand through changes in government sp...

Instead, they can draw on contractionary fiscal policy tools, such as increasing taxes or decreasing government spending or government transfers. Doing any of these things will decrease Marthlandia’s aggregate demand, which leads to lower output, lower employment, and a lower price level.
- Automatic Stabilizers. Certain government expenditure and taxation policies tend to insulate individuals from the impact of shocks to the economy. Transfer payments have this effect.
- Discretionary Fiscal Policy Tools. As we begin to look at deliberate government efforts to stabilize the economy through fiscal policy choices, we note that most of the government’s taxing and spending is for purposes other than economic stabilization.
- Changes in Government Purchases. One policy through which the government could seek to shift the aggregate demand curve is a change in government purchases.
- Changes in Business Taxes. One of the first fiscal policy measures undertaken by the Kennedy administration in the 1960s was an investment tax credit. An investment tax credit allows a firm to reduce its tax liability by a percentage of the investment it undertakes during a particular period.
Alternatively, when the government reduces spending, it reduces aggregate demand in the economy, which again temporarily slows economic growth. As such, aggregate demand is expected to decrease in the short term when the government implements contractionary fiscal policy, regardless of the mix of fiscal policy choices.
Expansionary fiscal policy causes inflation by increasing aggregate demand which puts upward pressure on the price level. When the central bank engages in contractionary monetary policy it decreases aggregate demand, thereby decreasing the upward pressure on the price level.
Fiscal policy affects aggregate demand, the distribution of wealth, and the economy’s capacity to produce goods and services. In the short run, changes in spending or taxing can alter both the magnitude and the pat-tern of demand for goods and services.
