[有圖] 經濟補習同行內鬥！懸崖咳咳Vs 哈哈哈［2］

會/唔會出現 因為shortage 係講緊given price
如果發生咗d 事件 令qd 大於qs 可以出現price or non price
所以Necessarily imply 只有(1)
non price 會係 price ceiling 底下發生
price 會係 adjustable price 發生

我唔要食蟹啊

短暫shortage 再透過價高者得，adjusting 既過程咪 shortage ?

咁你個陣點分配資源？

兩邊會爭議係因為大家對shortage 時候seller 可否adjust price 有唔同assumption
如果price 會變 咁會直接變price comp
price fixed > non price

唔係shortage唔會出現, 而係已經被消除
唔識得given某一個price去睇shortage定surplus, 點樣得出均衡價錢喺邊

因為比price comp 消除所以可以無non price comp
non price comp 係price ceiling/ limited quantity and low price 裏最常見

有甜品未

以前中學補過一堂ANDREW
成堂吹水講笑 哈哈哈~

落堂剩係記得佢講佢偶像係馬丁路德金
次後3堂當豪比佢 無去上

次後轉投CLIFF既懷抱

我懷疑hahah都係諗：price會升到equilibrium,所以冇non-price competition
唔係ust個email咁掟出黎係冇意義。。。

價格管制固然會有非價格競爭
就算私有產權清晰界定, 利潤極大化嘅商家仍然有機會因為調整價格有成本而唔會即時調整價格但model入面好似係假設冇任何調整成本

我明你問咩
你係想講raise price 過程中都會有non price

不過 你要諗下如果seller 一下將price 升去above future eq price 咁就無左non price

其實可以諗下現實
seller 可以為左maxmise profit而唔允許non price

留名等甜品

Necessarily imply 嘅話 應該只有(1)
could imply 就 123
given a fixed price 13

唔撚係河蟹呀

呢個就係哈哈哈走去搵科大教授想證實嘅地方, 而科大教授係認同呢一點

你自己假設seller會overshoot已經係額外嘅假設

唔係額外假設 而係因為有must imply 所以你要假設晒所有情況 論證責任會更大

似

小弟錯 OK? 改翻 dse econ 咁簡單， 但係你話冇讀過econ 唔好討論會唔會太高估呢條題目既難度 稍微睇過下econ 第一課都識答

即係哈哈哈係想搵support, 有shortage就會有price increase, increase咗咪有新equilibrium, 有新equilibirum咪無咗shortage，咁咪唔駛有non price comp

哈哈哈係想咁？

無讀過econ
想知係邊個岩

老細角度實叫大家唔好搞大佢算數

其實只係定義問題，搞清咗定義，其實好多討論都好無謂

1. Price competition & non-price competition：

Shortage = demand > supply

所以呢度嘅competition係指buyers用咩方法競爭，所以唔關商家點競爭、點分配資源事。

2. Shortage

Shortage包唔包括短暫demand>supply，然後用price變返equalibrium？

以下取自Wiki：

In a perfect market, an excess of demand will prompt sellers to increase prices until demand at that price matches the available supply, establishing market equilibrium.

In perfect market, 雙方會以調節price達至equalibrium。

In economic terminology, a shortage occurs when for some reason (such as government intervention, or decisions by sellers not to raise prices) the price does not rise to reach equilibrium. In this circumstance, buyers want to purchase more at the market price than the quantity of the good or service that is available, and some non-price mechanism (such as "first come, first served" or a lottery) determines which buyers are served. So in a perfect market the only thing that can cause a shortage is price.

睇完呢段會清楚哂。Price出現問題無得競爭（有錢唔係大哂）先至會導致Shortage，所以呢個定義下：

Price competition failed -> shortage -> non-price competition

And of course有scarsity先有competition先有shortage

所以唔駛理會短暫定長遠，淨係睇定義已經冇得揀，(1) & (3)。

利申：冇讀過Econ

Shortage 邊係D>S

不是嗎

可否解釋下

Qd 同 demand都未識分，已經唔駛睇

巴打一樣還一樣
唔係識哂啲term、用啲equation堆砌先叫解釋架嘛
用返英文嚟睇我有冇解釋錯
請賜教
