[請益] 請問一個題目
In which of the following ways is a monopolist different from a perfect
competitor?
(A)average cost will continuously drop as output expands.
(B)price is above marginal cost.
(C)the demand curve for the industry has a negative slope
(D)all of the above are true.
這題我想了很久覺得答案是D吧
(A)獨占廠商不就是享有規模經濟所以平均成本會持續降低(不太確定觀念對不對)
(B)是因為P大於MR所以在MR=MC時P>MC
(C)獨占廠商面對負斜率需求曲線 完競廠商面對水平需求曲線
可是書本上的答案是給B
想請問大家怎麼想的
