问题
If, as income increases, the demand for product X decreases, X is said to be a/an______.
选项
A、substitute good
B、complementary good
C、inferior good
D、normal good
答案
C
解析
答案为C项。substitute good“替代品”。当两种商品为替代品时,一种商品价格上升将导致另一种商品需求增加;一种商品价格下降导致另一种商品需求下降。如汉堡与三明治。inferior good“低档物品”,其需求与消费者的收入水平成反方向的变动,即随收入水平提高而减少,随着收入水平的下降而增加。normal good“正常物品”,其需求与消费者的收入水平成同方向的变动,即随收入水平提高而增加,随着收入水平的下降而减少。本题中,商品x的需求是随着收入的增加而减少的,属于低档商品,故选C项。
