问题如下:
For the December consumption basket in Exhibit 1, the value of the Paasche index is closest to:
选项:
A.
116.
B.
148.
C.
160.
解释:
A is correct.
The Paasche index uses the current product mix of consumption combined with the variation of prices. So for December, its value is
(120 × 1 + 50 × 0.8)/(120 × 0.9 + 50 × 0.6) = (160/138) × 100 = 115.9
考点:Paasche index
派许指数下,使用当期消费篮子参与计算
直接套用公式,带入数据得到物价指数:
(120 × 1 + 50 × 0.8)/(120 × 0.9 + 50 × 0.6) = (160/138) × 100 = 115.9
派许指数有一个是根号下L和P的相乘,这个公式是用来算什么的
