Which describes the role of automatic stabilizers in the economy? Automatic stabilizers are discretionary changes to taxes, government spending, and transfers that Congress makes in an attempt to improve the economy. Automatic stabilizers refer to industries that are not subject to the fluctuations of the economy, and therefore moderate the effects of recessions. Food, housing, and the military are examples of these industries, which are usually more stable than the rest of the economy. Automatic stabilizers have a similar impact as discretionary fiscal policy but occur automatically, without action by the government. Automatic stabilizers increase aggregate demand during recessions and reduce aggregate demand during expansions. Automatic stabilizers are changes in the money supply that occur automatically when inflation or unemployment occurs.
