題目
A monopolist producing only one product has 2 plants with the following
marginal cost functions: MC1=20+2Q1 and MC2=10+5Q2 , where MC1 and
MC2 are the marginal costs in plants 1 and 2 , and Q1 and Q2 are the levels
of output in each plant , respectively.
一獨占廠商擁有兩家工廠來生產一產品,
而這兩家工廠的邊際成本函數分別是
工廠1: MC1=20+2Q1
工廠2:MC2=10+5Q2
﹝Q1 和Q2是分別是1和2工廠的生產標準﹞
If the firm is maximizing profits and is producing Q2=4 , what is Q1=?
若此廠商追求最大收益,且 Q2=4時,求 Q1=?
我的解題
∵根據firm多工廠的均衡條件 → MC1 = MC2
且已知20+2Q1 = 10+5Q2 ,且Q2 = 4
∴ Q1=1/2(-10 + 5Q2) = -5 + 2.5Q2 = -5 + 10 = 5
這樣解對嗎?
因為不是本科系的...所以解題有點沒把握@@
