为什么A不对？
我的理解是：首先，用的是基期篮子。其次，虽然质量向好，但价格没变。所计算出来拉氏指数没变化的。
何老师讲课的例子是：用基期篮子，质量向好且价格上涨，计算的拉氏指数是bias 高估的。
问题如下图：
选项：
A. 
B. 
C.

•Inflation rate is the percentage increase in the price level, typically compared to the prior year.
inflation rate就是价格变动的百分比，商品涨价了 inflation rate >1；降价了， inflation rate <1；价格不变， inflation rate=1。
商品质量提高了，但是价格没变，说明该商品实质上是降价了，说明商品实际上deflation，该商品inflation rate应该是小于1。但是 inflation rate 计算的时候没有考虑到质量的提高，在考虑该商品的时候，算成了它的inflation rate=1，所以是高估。

inflation rate为什么会以1作为分界点？不是应该是零吗？何老师视频里讲的也是deflation的情况是inflation rate is negative
