標題[經濟] GDP 與 CPI

科目： 經濟
問題： 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與b 的算法對嗎？
c 小題的判斷方法是？？
因為找不到線索 我只想到大於小於,但是不清楚是對還是錯

我改了數字了 可是答案還是一樣= _ ="
GDP Deflator = (P1*Q1 +p1*q1) / (P0*Q1 +p0*q1)
CPI = (P1*Q0 + p1*q0) / (P0*Q0 +p0*q0)
P1=該期a物價 Q1=該期a數量
P0=基期a物價 Q0=基期a數量
p1=該期b物價 q1=該期b數量
p0=基期b物價 q0=基期b數量
這樣對嗎??
