问题： Suppose that the residents of closed economy, Proteinland, spend all of
their income on ham and chicken. Below are some comsumption date for Proteinland
year Price for ham Q for ham P for chicken Q for chicken
2006 6 100 8 50
2007 12 170 6 60
a.Using 2006 as the base year, calculate the GDP deflator for 2007
b.Using 2006 as the base year, calculate the comsumer price index for 2007
c.Some argues that CPI tends to overstate that increase in the cost of living
from one year to the next. Can you use the above example to comfirm or refute
that argument? Why or why not?
我自己的想法：
a. GDP deflator = ( 12*170 + 6*60 ) / ( 6*170+ 8*60) = 2400 / 1500 * 100%=160%
b. CPI = ( 12*100+ 6*50) / (6*100+8*50) = 1500 / 1000 *100% = 150%
c. refute because CPI < GDP deflator
我不懂的地方：
a与b 的算法对吗？
c 小题的判断方法是？？
因为找不到线索 我只想到大于小于,但是不清楚是对还是错
