问题如下:
Assume the GDP in Country X of year 2016 and 2017 is $200 billion and $220 billion respectively, using 2016 as the base period, the GDP deflator for 2017 is closest to
选项:
A.110
B.90.9
C.10
解释:
A is correct.
The GDP deflator is calculated as 100*(220/200)=110.
考点: GDP deflator
解析:直接依据定义计算100*(220/200)=110.
2016的GDP是200, 2017的GDP是220,算GDP deflator 的公式是(value of current year output at current year prices)/(value of current year output at base year price),显然200不是以2016为base year的2017的GDP啊,为什么可以用220/200?
