Econ CE 疑難

2007-04-16 7:27 am
joint demand 的定義是when price of good X decrease will lead to demand of good Y increase.

如果demand for good X increase, 是否會令demand for good Y increase??

✔ 最佳答案
係…
求其諗個例子…
如果CD player既demand increase…可能係因為潮流之類既關係啦…
自然demand for CD都會increase啦…

其實只要係多左人買good X, demand for good Y就會 increase…唔理原因係價錢定其他因素

To googoola16: 似乎你唔知咩叫引申需求(derived demand)大家要分清楚 Joint demand 同derived demand.Joint demand係:Two goods togerther satisfies one wants.Derived demand:One good is the factor of production of the other.唔通你想話CD係CD player既factor of production? 唔好講笑啦…

只要係Joint demand, 一樣野多左人買, 另一樣都會多左人買, 如果demand for CD 增加 , demand for CD player 都會增加,我都做過呢d passpaper嫁\ ___ /我ECON A嫁\ ____ /

呢個係引申需求
若CD 既demand增加,即係CD本身既price沒有改變,只係另一種相關連既野平左
至於上述例子中,CD player既需求量上升,就會導致CD既demand增加!!!!!(相信你都知需求同需求量係唔同)
