Suppose that in a particular economy, the multiplier is equal to 5. In terms of aggregate demand and aggregate supply, this value for the multiplier means that after an increase in investment (假设在特定的经济体中,乘数等于5.在总需求和总供给方面,乘数的这个值意味着投资增加后——中文由在线翻译而来,仅供参考)
A.
at each level of real GDP, the aggregate demand curve shifts upward by an amount equal to 5 times the change in investment.在实际GDP的每个水平上,总需求曲线向上移动等于投资变化的5倍。
B.
at each level of real GDP, the aggregate supply curve shifts upward by an amount equal to 5 times the change in investment.在实际GDP的每个水平上,总供给曲线向上移动等于投资变化的5倍。
C.
at each price level, the aggregate supply curve shifts rightward by an amount equal to 5 times the change in investment.在每个价格水平,总供给曲线向右移动等于投资变化的5倍。
D.
at each price level, the aggregate demand curve shifts rightward by an amount equal to 5 times the change in investment.在每个价格水平,总需求曲线向右移动等于投资变化的5倍。
