标题请问一个弹性的问题
时间Fri Apr 28 22:22:03 2006
A perfectly inelastic supply curve in a competitive market:
a. Means the equilibrium price must be zero.
b. Implies a vertical demand curve.
c. Exists when firms cannot vary input usage.
d. Says the market supply curve is horizontal.
------------------------------------------------------------
答案是c,我只知道perfectly inelastic supply curve是vertical的,
也就是产品价格的改变并不能去影响厂商供给的量,
请问一下这要怎麽推论到c答案的那个结论阿,谢谢!!
