Automatic Stabilizers

The Purpose of Automatic Stabilizers

The purpose of automatic stabilizers is to adjust aggregate demand in the economy by increasing or decreasing income. During recessions, automatic stabilizers increase income to stimulate demand. During periods of economic growth, automatic stabilizers decrease income to suppress aggregate demand and reduce growth. Importantly, automatic stabilizers require no government intervention. They have built-in mechanisms for activating, making them useful as a quick response to economic recessions.

Automatic Stabilizers During Recession

The fundamental concept behind automatic stabilizers is to increase aggregate demand when the economy is declining and to suppress aggregate demand when the economy is growing. To better understand how automatic stabilizers work, let’s look at an example of how an automatic stabilizer can increase aggregate demand during a recession, when they are implemented to be expansionary.

Unemployment insurance is a classic example of an automatic stabilizer; it provides temporary financial assistance to workers who get laid off and need to consume less. During a recession, many people may lose their jobs. As household income falls, consumption falls, aggregate demand falls, and GDP falls. Unemployment insurance seeks to prevent job losses from having this impact on GDP.

This helps dampen the negative effects of a recession on aggregate demand. Unemployment insurance is also something people can qualify for right away without the need for additional government legislation, making the policy “automatic.”

Automatic Stabilizers During Economic Growth

Automatic stabilizers can also work to moderate consumption during times of growth. In this case, they are referred to as contractionary. When the economy is growing rapidly, it may be wise to limit aggregate demand to control inflation. Automatic stabilizers can help with this. Let’s look at an example of how an automatic stabilizer can decrease aggregate demand during an expansion.

Progressive tax brackets are a type of automatic stabilizer that can help moderate increases in economic growth. They work by increasing the tax rate as income grows.

After the government designs and implements a progressive income tax system and/or corporate income tax system, the tax rates will automatically adjust based on an individual's or corporation's actual income. Figure 2 shows a tax calculator. If an individual receives a pay cut, their tax rate will automatically decrease without any additional action on behalf of the government. This will help to lessen the reduction in aggregate demand.

Automatic Stabilizers Example

There are many examples of contractionary and expansionary automatic stabilizers that all help to minimize the fluctuations in GDP. Unemployment insurance is an example of an expansionary automatic stabilizer, while progressive income tax and corporate income tax are examples of contractionary automatic stabilizers.

Another important type of automatic stabilizer is government social services programs, also called welfare programs, such as food stamps. Any government transfers to people experiencing lower income are acting as automatic stabilizers. Those transfer payments are helping to boost individuals' and families' ability to consume, thus increasing aggregate demand and supporting GDP.

Automatic Fiscal Policy Stabilizer

Automatic stabilizers are a crucial part of governments’ fiscal policy. Fiscal policy is how the government spends money and taxes income in order to influence economic conditions. During a recession, the government will need to take steps to mitigate economic harm. While some actions like stimulus packages can help, they also take a long time to design, get voted on, and pass.

The economy often needs support to stimulate or dampen demand much more quickly. Automatic stabilizers are extremely useful in this regard because they activate without any action required from the government. Once a government has created automatic stabilizers, they work to stabilize fluctuations in GDP on their own.

It's important to note how these changes are automatic. Consider a progressive tax system. When an economy is starting to overheat and inflation is soaring, the rise in incomes will increase not just tax amounts, but tax rates, and this serves to automatically curb demand. Likewise, when an economy is slipping into recession and unemployment is on the rise, the tax rates will fall due to lower incomes, and this serves to automatically help increase demand, as does unemployment insurance too.
