1.
假設玉米市場需求:Qd=200-P
Qs=50+0.5P
現在政府設150元為玉米市場目標價格,並承諾購買所有在該價格下的超額供給
那就目前市場供需,政府需花多少元購買玉米?
Ans:11250
此題均衡P=Q=100,
超額供給量P=150時 Qd=50
Qs=125
超額供給為75
政府花75*(150-100)=3750 收購?
還是哪裡有問題?

2.
假設X材市場需求q=432-2p,市場供給q=12+3p,政府設上限60,另一方面
補貼生產者以避免市場短缺,則每單位補貼為?
Ans:40
只算出原均衡p=84 q=264,接下來是用生產者剩餘的變化去解嗎?
還是要算出P=60時的Qs、Qd?
