以下出自100年高考選擇
1-政府沒有對雞蛋市場課稅前,雞蛋市場之供給與需求函數分別為:P=160-60q
與P=61+3q,其中P、q分別為雞蛋之價格與數量,假設政府對每箱雞蛋課從量稅27元,則
課稅後消費者多付多少元?
A)29元 B) 27元 C) 18元 D)16元
Ans:C) 18元
疑問:請問我的解題方向是不是錯了呢? 因為算出稅前的均衡P=160-60q=61+3q
q=11/7 p=460/7 後就有點卡住,因為稅前均衡的數字好像有一點怪
請問應該怎麼解呢?
2-張三和李四猜拳,張三贏時可得50元,輸時將損失60元,這是何種賭局?
A)對張三和李四皆是公平賭局
B)對張三和李四皆是不公平賭局
C)對張三是公平賭局,對李四是不公平賭局
D)對張三是不公平賭局,對李四是公平賭局
Ans:B)
疑問:請問為何不能選D
我的想法如下:
公平賭局是預期π>0
張三的預期π=0.5*50-0.5*60=-5
李四的預期π=0.5*60-0.5*50=5
