Explanation:

Automatic stabilizers are fiscal policids that reduce the impact of economic fluctuations automatically without interference by the government or policymakers.

Examples of automatic stabilizers are progressive income tax and transfer payments such as unemployment insurance payments.

Progressive income tax tax those with higher income more and those with less income less. In an expansion, it regulates income by taking more tax and increases disposable income in a downturn by taking less tax.
