「試當真賣飛」驚現DSE 經濟卷：「說明了價格的_________功能？」

Econ 本身就係教人點賺到盡, 搵盡一分一毫<- 不學無術，信口開河

痴撚線，都唔係經濟題，中文題都有問題。

A.更多資源可以分配到該表演的製作。就算賺到盡都冇話放落製作到，賣一蚊同十萬都可以同製作無關。

B.這安排可以確保門票沽清。依個方法係可以高大利潤化下沽清，但唔係確保，可以全香港都冇人睇，送都唔撚要

C.門票售予最高價值的賣家。都唔撚知佢噏乜鳩，sell to seller，售門票畀賣家，唔係買賣，賣俾賣家，邊撚個翻譯，邊撚出題
改為連登用字：門票售予付最高價的買家。


D.這些門票是以先到先得準則分成。除咗先到先得個價格去撚咗邊



痴撚線中文痴撚線題目。

冇讀econ 都估岩左

估都估中

SPIN 唔到就鳩屌

的確係price discrimination
但你咁講當試當真set price =300
有人本身肯俾一千但可以淨係俾300
咁試當真夠有「損失」啦

根本就係無囉
本身就係"willing to pay"
越貴買越早買就越肯定有飛
係連登仔係都要屈到負面
根本price "discrimination"喺econ都係中性字眼嚟

你係咪搞錯Pareto efficiency 同fairness ？

Perfect price discrimination 下
Total surplus= consumer + producer surplus 仍然係maximised ，只不過係consumer surplus =0
仍然有可能係efficient 喎

佢唔係exactly 定義既price discrimination.

Price discrimination 係要用特徵區分不同種類customer, 例如學生價，長者價，女仕價。
[Btw, 會員價唔係price discrimination, 因為俾左membership 錢係人都可join 會員，之後有平，呢個只係另一種收費安排。除非特殊會eg 馬會/hongkong club]
試當真係cap 盡customer surplus, 不過唔係用price discrimination 既方法，小心小心

最撚仆街係考評局出錯係唔使道歉唔使咩鑊

而唔知幾撚多考生俾佢咁玩成個人生都唔同曬

香港教育最現實的一課

我不嬲都話試當真咁樣賣飛即係自己做黃牛劏鳩支持者
係個陣班弱智連登fans係咁吹捧試當真

屌，econ用中文讀

Price differentiation essentially relies on the variation in the customers' willingness to pay[2][3][4] and in the elasticity of their demand.

Within the broader domain of price differentiation, a commonly accepted classification dating to the 1920s is
Personalized pricing" (or first-degree price differentiation) — selling to each customer at a different price; this is also called one-to-one marketing.[9] The optimal incarnation of this is called "perfect price discrimination" and maximizes the price that each customer is willing to pay.[9]

"Product versioning"[2][11] or simply "versioning" (or second-degree price differentiation) — offering a product line[9] by creating slightly different products for the purpose of price differentiation,[2][11] i.e. a vertical product line.[12] Another name given to versioning is "menu pricing".[10][13]

"Group pricing" (or third-degree price differentiation) — dividing the market into segments and charging a different price to each segment (but the same price to each member of that segment).[9][14] This is essentially a heuristic approximation that simplifies the problem in face of the difficulties with personalized pricing.[10][15] Typical examples include student discounts[14] and seniors' discounts.

似乎係你搞錯多d喎 你講緊既group pricing 只係一個specific case of price discrimination

你唔識就收番埋啦
連登好多中學生睇架

效率嘅定義係總社會盈餘最大化
呢個定義唔係我作出黎，唔好你以為效率係乜嘢就係乜嘢


試當真只係蠶食咗部分消費者盈餘(consumer surplus)，成為試當真嘅生產者盈餘(producer surplus)。（橙色部分）

實施價格歧視前
生產者盈餘係紅色
消費者盈餘係紫色+橙色部分

實施價格歧視後
生產者盈餘係橙色+紅色
消費者盈餘係紫色

請問實施價格歧視後，總社會盈餘（=生產者盈餘+消費者盈餘）有咩改變？？？？

所以呢個價格歧視根本就冇影響市場效率

ps 經濟學名詞全部都有佢嘅嚴格定義，唔係你作出黎，or你覺得係就係嘅

pps 樓主去讀下econ選修單元1啦，唔好出黎獻醜

你幫下廉署
考評局幫下你
好公平啫

癡撚線
一個dse Econ Post 因為有試當真（既haters）
引左勁多錯既Econ statements

仲有個d「考評局暗示乜乜乜」既comments

做佢d加盟店蝕撚到仆街

出題果位可能係fans

你講緊嘅效率最大化
就係均衡價格之下供應需求完全平衡先會發生

價格歧視之下必然出現不效率
因為會出現dead weight loss


呢種價格歧視 就係p= muv

試當真 cap晒 consumer surplus

所以先話愈支持試當真 Muv 愈高嘅人損失愈多surplus

吓 答案C就係講緊試當嘅賣飛方法就是睇錢份上
而佢地就係消滅消費者盈餘達致利益極大化
係無屌錯

柒夠未？
夠就好搵窿捐喇

Econ Framework 入面所有firms 都係profit maximising
Dse Econ 淨係講positive economics
無所謂係咪屌緊人
唔好將你d個人觀感混入條題目

你嘅講法駁改變唔到事實: 佢地想盡量吞併消費者盈餘


當然現實唔存在完美價格歧視
佢地唔可以向每一位消費者談判 因為欠缺效率

佢地唔係唔想cap盡consumer surplus

佢地都想完美價格歧視
只係現實佢地做唔到將市場劃分到咁仔細到每個消費者
所以變成一個價位一小批買家嘅價格歧視
但一樣係搶咗Consumer surplus 嘅仆街


但概念上佢地目標係一樣

盡量食晒consumer surplus 食得幾多得幾多

而唯一不變嘅係
佢地搶咗消費者surplus部份 據為己有



對市場最理想:


試當真獨吞surplus嘅理想：


現實係佢地無可能逐個消費者獨立地訂價 所以唔係絕對完美價格歧視：

但P individual = MUV individual 的確係佢地嘅目標
只係現實做唔到百分之百

唔係個人觀感

係答案c 講明目的係將門票先賣俾MUV更高嘅人
即係優先劏consumer surplus 最高嘅消費者

呢個係好客觀嘅事實
