: 这段话的意思有看没懂...> <(查了字典还是不太懂)
我的翻译@@:当该单位高层允许车费上涨10% 但司机们的收入只上升约5%
: : of demand for taxicab riders? What were taxicab drivers assuming about the
: : elasticity of demand?
: : 不过,我不太懂题目的意思
: : 对rider而言,弹性是0.5吗??
挖 这个看起来简单的题目感觉又令人困惑~!!
我也是最近才在念经济学 大家一起讨论看看@@
价格上升了10% → 收入上升5% → 代表消费量下降5%吧@@?
这样应该需求弹性∣Ed∣=0.5
那供给弹性的话 我猜~
他们价格上升10% → 预期收入也上升10% → 代表供给量不变
所以他们的供给弹性Es= 0
个人现丑了>"<
