Two goods are joint supply if one of them is a by-product of the other.
An increase in price of Good X results in an increase in supply of Good Y.
Good X and Y are in joint supply.
Example:wool and mutton
If the price of mutton increases,suppliers are more willing to produce mutton and hence its quantity supplied increases.
In this case,more sheep have been killed and the suppliers will also increase the quantity supplied of wool at each level of price.
Therefore,the supply curve of wool shift to the right,the equilibrium price decreases and the quantity transacted increases.
既然An increase in price of Good X results in an increase in supply of Good Y.
咁點解mutton貴左供應多左,佢個副產品wool唔係一樣貴左供應多左而係愈便宜供應愈多?

why wool需求多咗, 價錢就一定平咗-.- I am a supplier,If wool需求多咗,why I can't enchance the price of wool to get more money -________-?

wai ting ,請問係咪因為依家mutton需求多左so我作為一個supplier自然想supply more mutton to earn more money,但係依家要supply多Ｄmutton自然 need to kill more sheep.So I will get more wool from the sheep,so 我自然supply多左wool, 但係在市面個需求並沒增加到所以我降低＄來賣過多既出去? 假如您有time可唔可以幫我答埋另外我問既２條ECON問題ar-____________-? plx
