用回文的好了不然好像會超過三行@@
話說回來
供給是需求決定的
需求基本上又是價格決定的
總覺得價格不管怎麼看都比數量還像自變數@@

推 moondark92:習慣吧,再說其實供應曲線的P其實與邊際成本有關 11/14 17:57
→ moondark92:而邊際成本是Q的函數..... 11/14 17:58
推 moondark92:供應者P(Q) = MC(Q) + 期待利潤(MC(Q),TFC,,,,,,,) 11/14 18:09
→ afflic:供給面有點複雜就是... 11/14 21:21
→ afflic:完全競爭市場的話就是先決定價格才決定數量的 11/14 21:23
→ afflic:其他市場則是量價互相調整以達到最大利潤為主 11/14 21:26
推 moondark92:那就當作隱函數處理吧,就沒有誰是誰的函數問題 11/14 21:31
推 moondark92:不過完全競爭市場條件下,價格趨向等於生產成本...... 11/14 21:33
→ moondark92:而生產成本還是Q的函數 11/14 21:34
→ afflic:所以說供給面比較複雜,不過需求面就比較單純 11/14 21:36
→ afflic:供給面量價互相影響,需求面基本上價格影響數量 11/14 21:38
推 moondark92:如果是中間產物市場的需求就很難說了 11/14 21:39
→ moondark92:對任何生產者來說,對其原料中間市場是需求,而此需求又 11/14 21:40
→ moondark92:與供應市場連結 11/14 21:41
→ afflic:嘛中間市場我不太清楚就是了,不過感覺比較屬於特例? 11/14 21:42
