Answer:
C.
Explanation:
Automatic stabilizers are line items that automatically move the budget balance toward deficit when the output gap is negative and toward surplus when it is positive, even if there are no changes in tax or spending laws.
For example, income tax revenue increase when the economy expands, pushing the balance toward surplus. Or, unemployment benefits increase when the economy is in recession, pushing the balance into deficit.
By adding to aggregate demand during downtums, automatic stabilizers moderate the business cycle.
