邊際成本 - 經濟

Table of Contents

※ 引述《yamitigo (鴨米鐵劍)》之銘言:
: 學校:FCU
: 教師:吳朝欽
: 科目:經濟學
: 題目:
: Marginal cost equals:
: (i) change in total cost divided by change in quantity produced

△TC
MC = ------ ,在微量變動時, MC = dTC/dQ
△Q



: (ii) change in variable cost divided by change in quantity produced


TC = TVC + TFC

dTC/dQ = d(TVC+TFC)/dQ

= dTVC/dQ + dTFC/dQ

然後dTFC/dQ 會等於0

所以 dTC/dQ = dTVC/dQ





: (iii) the avarege fixed cost of th current unit
: (A) (i) and (ii)
: (B) (ii) and (iii)
: (C) (i) only
: (D) All of the above are correct.
: 我的想法:
: 我個人覺得是(C)
: 但是答案卻是(A)
: 因為邊際成本的話
: 不是應該△Total Costs/△Quantity才對嗎??
: 還有請各位了.....
