Explanation:

Built-in stability, also known as automatic stabilizer means that with given tax rates and expenditures policies, a rise in domestic income will reduce a budget deficit or produce a budget surplus, while a decline in income will result in a deficit or a lower budget surplus.

Simply stated, Built-in stability are economic system or policies which are involuntarily triggered without precise government intervention in order to create stability in the economic cycle of a country. They are systems that automatically shore up or strengthen the Gross Domestic Products (GDP) without the intervention from the government.

For example, taxation usually decreases during a recession because individuals and businesses make less, which leads to unemployment and an increase in social security funds.

Also, it is necessary to note that built-in stability only offsets economic activity fluctuations partially.
