前幾日考一題簡單S5題都比較多同學錯

首先題目105跌到102，為price index之一的GDP deflator

佢代表了price level實際指數，即代表price level跌，持續的下降可看作deflation

在Nominal GDP與Real GDP相同時為100，亦在基礎年base year定為100

本身就沒有%change性質

NOMINAL GDP/REAL GDP ×100 = GDP Deflator

所以無論大於100 (只反映Nominal GDP 數值 > Real GDP)定少於100(只反映Nominal GDP 數值 < Real GDP)，只是price level 比base year高或低的意思

只屬position 位置

並不代表price level升跌

如果要睇升定跌，就要有兩個實際數字

例如GDP deflator由90升到92

代表都係price level升，持續上升可看作inflation

以上就是簡單data理解，切勿混淆

故此(1)錯

另提多一點，當大家Growth rate 或inflation rate下降時

才可稱price level為升得慢左

(3)錯，係因為index只反應整體的general price level

並不代表All goods and services都一定price跌

Ans D
