In one sentence
Automatic stabilizers are built-in tax and transfer mechanisms (like progressive taxes and unemployment insurance) that automatically dampen recessions and booms without new legislation.
Budget sensitivity (a compact representation)
Let the primary balance be $B(Y)=T(Y)-G-TR(Y)$, where taxes $T$ rise with income and transfers $TR$ fall with income. Then:
[
\frac{dB}{dY} > 0
]
so a fall in $Y$ automatically worsens the balance (supporting demand), and a rise in $Y$ improves it (leaning against booms).

Background
Automatic stabilizers are economic mechanisms that immediately respond to changes in economic conditions, mitigating the volatility of the business cycle. These tools are built into the economic system and operate without requiring new government action or legislation at each juncture.
Historical Context
The concept of automatic stabilizers gained prominence during the 20th century, particularly as economists and policymakers sought to design economies more resilient to the booms and busts characteristic of capitalism. The term became crucial following the Great Depression and World War II, when Keynesian economics advocated for mechanisms to stabilize the economy automatically.
Definitions and Concepts
Automatic stabilizers typically include progressive tax systems, unemployment insurance, and welfare programs. For example, during an economic downturn, tax revenues fall, and government spending on programs like unemployment benefits rises, which helps to sustain demand and counteract the recession without requiring additional legislative measures.
