跪求經濟學題目翻譯~感謝感謝

1.Suppose that,at the market clearing price of natural gas,

the price elasticity of demand is -1.2 and the price elasticity

of supply is 0.6.What will result from a price ceiling that is

10 percent below the market clearing price?

Update:

麻煩請高手順便解題一下~~

解答是寫18%

但我想知道過程~

謝謝~^^

    No, demand and supply curves do not necessary be linear.

    翻譯

    假設天然瓦斯在市場結清(均衡)時,需求的價格彈性為-1.2

    供給的價格彈性為0.6。這時在市場結清(均衡)價格下10%

    (九折)設定價格上限會有什麼結果????

    -----------------------------------------------------------------------------

    需求(供給)的價格彈性定義為

    ( dQ / Q ) /( dP / P ) = 價格改變1%的情況下,需求(供給)數量改變的百分比

    現在題目中說到在均衡價格減價10%的價格設定價格上限

    所以需求改變為10%*-1.2=-12%

    同理供給改變為10%*0.6=6%

    題目中只問說結果怎樣????

    看來應該是問說供給跟需求的差距(超額供給)為多少=6%-(-12%)=18%

    Linear is "never" remain elasticities the same.

    Since, you persist that it's linear.

    Suppose a linear demand P=10-Q

    ( dQ / Q ) /( dP / P )= (dQ/dP)X(P/Q)

    So,dQ/dP=1, is constant.

    What happen to P=0 and P=5

    one elasticity is 0 and the other is 1

    You can replace "point easticity" with "arc elasticity"

    Well, as my introduction "大家討論練功夫 "

    To discuss is to learn.

    I assume that both the demand and supply are linear?

    2011-06-13 22:39:16 補充:

    If they are not linear, how can you assume that the elasticities remain the same at the price ceiling in question as in market clearing price?

    2011-06-15 06:15:49 補充:

    You are right.

    I was thinking about the slopes instead of the elasticities.

    Sorry for the confusion.

    1.假設,在清除的天然氣價格的市場需求的價格彈性是 1.2 和價格彈性供應的是 0.6.What 將導致從價格上限就10%低於市場結算價錢?
