问题如下:
To eliminate the substitution bias in the calculation of consumer price index, the most appropriate method is to:
选项:
A.adopt the Hedonic pricing.
B.adopt a Paasche index method.
C.use Fisher index.
解释:
C is correct.
Hedonic pricing is a technique to adjust for product quality. The substitution bias can be adjusted by Fisher index, which is the geometric mean of the Laspeyres index and the Paasche index.
考点:Hedonic pricing
解析:Hedonic pricing是一种对产品质量进行调整的技术。替代偏差可以通过费雪指数进行调整,费雪指数是Laspeyres 和Paasche index的几何平均值。

光看上面这句不是很懂。。
谢谢老师
