问题如下:
Price elasticity of demand for a good will most likely be greater if:
选项:
A.there are no substitutes for the good.
B.consumers consider the good as discretionary.
C.consumers spend a small portion of their budget on the good.
解释:
B is correct.
Price elasticity of demand is likely to be greater for items that are seen as optional or discretionary.
考点:影响需求价格弹性的因素。
解析:
影响需求价格弹性的因素有四点:
Availability of substitutes指替代品容易获取程度,商品容易获取弹性大,不容易获取则弹性小。
Relative amount of income spent on the good 商品花费占收入比。比重大弹性大。比如买房子。
Time since the price change.商品价格变化后的时间,价格改变后时间越长,消费者的机动性越大,弹性越大。
Whether the good or service is seen to be discretionary or non-discretionary商品是否是必须需要的。如果消费可以砍掉,那么弹性就比较大。B选项正确
老师你好,不是很明白题目的意思“一个商品的需求弹性大于会最有可能大于。。if以下几种情况” 那题目中的greater是greater than什么呢,不是很理解,谢谢
