Automatic stabilisers are features of the economy that operate automatically to dampen fluctuations in national income. They are particularly important in helping to cushion the impact of recessions. The two main types of automatic stabilisers are the income tax system and the unemployment benefits system.

Income Tax: During a recession, national income falls, leading to lower tax revenues. This reduces the amount of money the government has available to spend, effectively increasing disposable income for consumers. This increased disposable income stimulates consumption, leading to a rise in aggregate demand and helping to pull the economy out of recession. Conversely, during an expansion, higher national income leads to higher tax revenues, which helps to restrain demand and prevent overheating.

Unemployment Benefits: During a recession, unemployment rises. This leads to an increase in the amount of money spent on unemployment benefits. This provides a safety net for those who have lost their jobs, maintaining their consumption spending and preventing a sharp decline in aggregate demand. This increased spending helps to support the economy during a downturn. During an expansion, unemployment falls, reducing the expenditure on unemployment benefits, which has a dampening effect on aggregate demand.

The effectiveness of automatic stabilisers depends on the size of the multipliers associated with these stabilisers. A larger multiplier means that a given change in national income will lead to a larger change in aggregate demand. However, automatic stabilisers are not a perfect solution. They are automatic, meaning they do not require deliberate government action, but they may not be sufficient to fully counteract the effects of a severe recession. Furthermore, the full impact of automatic stabilisers may take time to be felt.

In conclusion, automatic stabilisers play a crucial role in smoothing out economic fluctuations, particularly during recessions. They provide a built-in mechanism for stabilising the economy without requiring active government intervention. However, they are often complemented by discretionary fiscal policy to achieve greater stability.
