The price of hot dogs increases by 22% and the quantity of hot dogs demanded falls by 25%. This indicates that demand for hot dogs is______.
选项
A、elastic
B、inelastic
C、unitarily elastic
D、perfectly elastic
答案
A
解析
答案为A项。elastic“富有弹性,弹性大于l”。需求量的变动率大于价格的变动率,需求量对价格变动的反应比较敏感。Inelastic“缺乏弹性,弹性小于l”。需求量的变动率小于价格的变动噩,需求量对价格变动的反应欠敏感。unitarily elastic“单位弹性,弹性=l”。需求量和价格的变动刚好相等。perfectly elastic“完全弹性,弹性=+∞”。只要价格有一个微小的上升,都会引起需求量的无穷大的变化率。本题需要计算需求的价格弹性,25%/22%=l.15>l,表示需求富有弹性,故选A项。
