100年高考3
某俱樂部的成本函數為TC=20Q+600,面對下列二群消費者Pa=100-qa和Pb=60-qb,
俱樂部老闆打算採用二階段訂價法,請問:
(1)如果老闆無法區別消費者是A或B,應該如何訂定會員費(T)和使用費(P)
Ans: P=40,T=200
不懂的地方是:
二部訂價法的重點在於,找出一個滿足兩個市場總利潤最大的訂價,
依公式解可求得P值為40,但若將此P值代入求總利潤,
得到的總利潤為2000---(20*20)+(40-20)*20+(40-20)*60,
但如直接以消費者A為主,令使用費(P)=20(MC),
而入會費(T)則為其全部的消費者剩餘3200---80*80/2(利潤大於前者).
但是蔡經緯老師及陳碩老師的解答皆相同(P=40,T=200),
不曉得是不是自己搞錯定義了,想破頭也想不出為什麼><...
還請版上大大解惑,不勝感激~~~
