Giving the following short-run demand and cost for a monopolistic
competitor, what output will the firm produce?
(以下為考題給的數據)
Price Quantity demanded Total cost Output
$10 1 $14 1
9 2 17 2
8 3 22 3
7 4 29 4
6 5 38 5
5 6 49 6
以下為我的想法:
設P=a-bQ , 分別用P=10,Q=1和P=9,Q=2聯立解得出a=11,b=1
所以MR=11-2Q然後就得出在Q=1~6下,MR依序為9、7、5、3、1、0
然後MC我不知道怎麼算。
以下是解答:
Q 1 2 3 4 5 6
MR 10 8 6 4 2 0
MC 14 3 5 7 9 11
所以廠商生產3單為時利潤最大,因為最接近MR=MC的條件
我的疑問:
1.MR和解答算的結果不一樣,不知道是哪出錯了?
2.MC不知道要怎麼從數據中去解?
希望各位高手能為在下解惑,謝謝各位!!
