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
