问题 Substitution and income effects of a change in the price of a good may help explain the ______relationship between______.

选项 A、direct…income and demand
B、direct…price and quantity supplied
C、direct…price and quantity demanded
D、inverse…price and quantity demanded

答案D

解析 答案为D项。direct relationship“正相关,正比关系”。与inverse relationship(负相关,反比关系)相对。无论是替代效应还是收入效应,都可以说明商品价格与需求量是负相关的。故本题选D项。
