這是經原課本第五章後面的question..
15.The demand and supply curves for T-shirts in Touristtown,U.S.A.,
are given by the following equations:
Qd = 24000 - 500P Qs = 6000 + 1000P
where P is mesured in dollars and Q is the number of T-shirts per
year.
(c).If two new stores that sell T-shirts open up in town, which of
the following might be the new supply curve?
Qs = 3000 + 1000P Qs = 9000 + 1000P
我的疑問是..
為啥咪商店增加..就會改變供給的函數呢??
基本上商店增加價格應該是不會改變吧??(如果不考慮競爭的因素)
而且每家店的成本應該也是一樣的..
那麼所發生的現象應該只是每家店所售出的總量變少了..
跟整個陣上的供給函數好像沒啥關係ㄟ..
還是題目的意思是..
要考慮到每家店為了要達到以往的銷售量..所作的降價措施嗎??
