题目

翻译The income effect refers to the effect on price and quantity demanded brought about by a change
The income effect refers to the effect on price and quantity demanded brought about by a change in consumer income

答案

所谓的“收入效应”指的是消费者的收入变化对产品的价格和需求带来的影响.
从经济课的角度说：
如果是普通消费品,消费者的收入提高会导致需求增加,继而导致价格上升.例如你的工资从3000变成8000,你可能就会考虑买一台新的游戏机.
如果是低档消费品,消费者的收入提高反而会导致需求减小.例如最便宜的方便面.你的工资从3000变成8000,你可能就想吃鱼吃肉了,而不吃方便面了.
