单选题 Which of the following statements best explains how automatic stabilizers work? Even without a change in fiscal policy, automatic stabilizers tend to promote: A. a budget surplus during a recession and a budget deficit during an inflationary expansion. B. a budget deficit during a recession but do not promote a budget surplus during an inflationary expansion. C. a budget deficit during a recession and a budget surplus during an inflationary expansion.

【正确答案】 C

【答案解析】Automatic stabilizers such as unemployment compensation, corporate profits tax, and the progressive income tax run a deficit during a business slowdown but run a surplus during an economic expansion. Therefore, they automatically implement countercyclical fiscal policy without the delays associated with policy changes that require legislative action.
