问一道题:NO.PZ2018062003000089

问题如下:

Last year, the annual value of final goods and services of country. A increased from $200 billion to $400 billion, the GDP deflator increased from 120 to 170. In this condition, the real GDP of country A increased by:

选项:

A.

35%.

B.

41%.

C.

52%.

解释:

B is correct.

Real GDP in the year before last was: $200/1.2= $167

Real GDP in the last year was: $400/1.7= $235

($235- $167)/$167=41%

考点: GDP deflator

解析:运用 GDP deflator 反解出一年前后的真实GDP数值,

一年前:$200/1.2= $167

一年后:$400/1.7= $235

在进一步求得真实GDP的增长率,($235- $167)/$167=41%

老师,请问200/1.2和400/1.7的含义是什么?不太了解。

GDP deflator上的分母分子是指不同时间生产总值的不同价格,那为什么要用真实价值除以这个数字呢?

2 个答案

DEFLATOR 分母是REAL GDP.用 REAL GDP去除以REAL GDP得到的数字是1

源_品职助教 · 2020年01月06日

因为DFLATOR=NOMINAL GDP/REAL GDP,

所以NOMINAL GDP/DEFLATOR= REAL GDP

200/1.2和400/1.7 求得就是个子年份的 REAL GDP

NO.PZ2018062003000089 用(170-120)/120再减1得出来的数不就是增长率嘛?
