问题如下:
Of the following statements regarding the Producer Price Index (PPI), which is the least likely? The PPI:
选项:
A.can influence the future CPI.
B.category weights can vary more widely than analogous CPI terms.
C.is used more frequently than CPI as a benchmark for adjusting labor contract payments.
解释:
C is correct.
The CPI is typically used for this purpose, while the PPI is more closely connected to business contracts.
考点:PPI
工业产成品的价格会影响到下游终端消费品的价格,因此PPI可以影响CPI而不是被CPI影响,所以A选项不正确。
B选项正确。比如有的国家天然气资源丰富那就用天然气,有的国家煤炭资源丰富那就用煤炭。考虑到有的国家,工业资源比较单一,所以相比CPI,PPI篮子权重的波动幅度会更大。
C选项错误。工人的合同如果有关于工资调整的条款也是依据CPI指数调整,而非按照PPI指数调整。毕竟工资花出去是用来买消费品。
看了回答我晕了,PPI到底是influence CPI还是reflect CPI呢,A选项本身的意思是对还是错呢,解答如果错了刘老师在一年前就说错了现在还没改回来啊。。。
