聽日校長應該會call 佢地番去照肺
撘錯線 sor巴打
個條唔係最後deleted 咩？
講真唔理邊個啱邊個錯，聽日考今日咳咳仲黎搞9哈哈，搞到佢啲學生冇曬信心，其實都真係幾冇道德。
不過如果真係出錯題目搞到啲學生錯concept都真係唔啱

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

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.

Completion by luck係唔係唔關price 事嘅competition ?咁係咪non piece competition?
唔明你個point 係咩

利申: 2013 DSE 全年跟足哈哈哈拎5* 覺得佢教d野幾啱考試用
但最深刻記得係佢講過 有時間就咪嘥時間去考啲名師mock，做多d pastpaper (佢嗰時自己無搞), 點知一兩年後就自己大鑼大鼓係度搞

姐係任何non-price competition 嘅出現 都可以係一種indicator 只係視乎你有幾信(幾probable)呢個indicator implies shortage
Prediction 嘅話 亂估一下 如果講queuing poisson model 呢啲queuing models可以用黎做prediction
實際應該都有economist研究呢啲野 有無重要性

Delete未必因為出錯，可以係因為分唔到學生高低。
講真我係學生嘅話都會迷惘，
不過有人點醒我錯少題好過出成績先發現錯死得咁不明不白

油價升，你真係唔會有shortage，只會有窮9買唔起油...
油價升，係真係唔會有shortage，只會有窮9買唔起油...imply係講之後嘅野咩？佢地既邏輯下，係連shortage都唔會發生，唔需要討論有咩競爭。There is no shortage even in a society, for the simple reason that all markets must be “cleared” in order to produce equilibrium situations. If equilibrium is not attained, no theory is implied, hence economics cannot explain behaviour. If the price of a good is controlled to below the market price, the alleged presence of the shortage, hence disequilibrium, simply means that we have no theory. It is not a fact. If queuing occurs, equilibrium may again be derived as a matter of routine, but then the market is again cleared—hence no shortage.
唔係shortage唔會發生，正因為發生shortage,所以一定會出現價格/非價格競爭/both。我完全唔明點解你否定咗P可以上升嘅可能，shortage嘅出現一定係p受到價格control?如果主要石油出口國突現減產，需求不變，供應減少嘅情況下，係咪出現shortage?油價係咪會升?唔好話咩唔講equilibrium,imply就係講之後嘅野，你自己諗一諗先答
利申：我真係唔知
