活雞供應少,因此賣得好貴..但仲好多人買
係有以下邊個情況?

change in demand
change in quantity demand
change in supply
change in quantity supply

CHANGE IN DEMAND掛

change in other factor

change in demand

會考D 野唔記得哂啦
CHANGE IN Qs 同Qd 得one and only one 個原因: change in price
但仲好多人買係點解
excess demand?.?
但係我又畫唔到個圖
我估係change in supply
有錯請指出

change in supply

我都畫唔到喎....

可唔可以成條問題打出黎

我未教到都知頭三個實錯

1睇條題目我就諗佢係inelastic.可惜冇得簡

change in qs+inelastic demeand

change in qd+inelastic demeand

其實不如我解下點解我個答案係change in supply

方便討論

Question: 活雞供應少,因此賣得好貴..但仲好多人買

首先 據我所知   O係CE程度

change in Qd / Qs ge原因 只係change in price

咁依家睇番題目啦

活雞供應少 <- drop in supply

賣得好貴<- 冇意思...好貴即係咩意思?-_- 5蚊可以好貴   有人覺得1蚊都好貴架喎-_-

            increase in price? drop in price?

            好貴即係咩?

但仲好多人買<- 冇意思again...好多者係點? 又唔代表excess demand呀...

                好多人買 但我到滿足晒佢地呀都得架!

所以我揀ge係drop in supply (change in supply)

其實可唔可以原原本本咁成條問題出? 因為樓主你就咁講好模糊 ......

應該係本身都有excess demand....
然後「活雞供應少」，我諗你係想講「活雞供應減少」，咁change in supply，條supply curve shift left~
咁個equilibrium price 會上升，然後equilibrium quantity 不變~
咁就做到price 上升，excess demand亦擴大...

唔知你條題目係咪真係我估咁，最後俾成條題目出黎~

4樣都有
