[ECON] 2017 DSE經濟科討論區(2)

total social surplus =mb -mc
但係計出尼=0

係total benefit-total variable cost bo

唔該巴打

問番relative price:
如果紅酒收per unit lump sum tax
高質紅酒既relative price in terms of 低質高酒下跌啦，而低質紅酒既relative price in terms of高質紅酒上高啦
問題黎喇，究竟係高質紅酒既Qt升低質紅酒既Qt跌.
定係
高低質紅酒既Qt都跌（因為price 上升）但高質紅酒升個rate較細

所以令average quality of wine consumed 上？？？

per unit lump sum tax 巴打你發明架???
per unit tax令到P升,Qd=Qt 就一定跌架喇
而係個quantity of wine sold, high quality wine takes a larger proportion of the wine sold

但係law of demand唔係可以套落relative price 咩？我就係卡左係呢度

你要明白既係relative price係講緊price of a good in terms of another good
price of low and high quality wine increases,qd decreases

The first law of demand asserts that when the relative price of a commodity increases, its quantity demanded decreases, and vice verse.
我記得本書講過d類似咁既野

係total benefit-total variable cost bo

點樣計.... 答案係咩

兩個都加左個per unit tax
Tax independent to price of red wine
After adding the cost
P(high quality wine) relative to P(low quality wine) drops
Qd of high quality wine increases relative to Qd of low quality wine.

total social surplus =mb -mc
但係計出尼=0

係total benefit-total variable cost bo

點樣計.... 答案係咩

係summation(mb-mc)
你由1st unit 既(mb-mc)逐個unit上，加到transacted unit 既(mb-mc)

姐係獨立黎睇Qt係跌不過relatively係升？

好驚炒粉
而家壓力好大

驚過你，數學mc抄撚左粉，得35 ~ 7

paper 1緊要d
你paper 1有9成就冇問題啦

9 條毛咩，坐底無16~20 分
3d錯左後面，log唔識，probi錯晒，18 最後錯左2 分，b2 條remainder theorem漏左個arbitrary constance無let( -1)

係summation(mb-mc)
你由1st unit 既(mb-mc)逐個unit上，加到transacted unit 既(mb-mc)

都係唔係好明 得QD QS 點變做MC MB 呢? 要點做

搵搵

真係驚paper 1多過paper 2 好多 做paper1 past paper 1啲分好波動

長卷好似難度上升緊

2012 2014真係出得一般
完全鬥小心，有做pp都會識個大概

2013 2015就應該係standard

2016因爲有evaluate會嚇親好多人，但實質難度同2015差不多。

預今年都係咁上下架啦。


Btw 其實dse出題改唔改得assumption

今年paper2唔好有externality
死比你睇

btw個d evaluate題其實都唔算好難答。講晒正/反 咁都差不多。比較擔心paper1
今年份份卷都玩野。Econ應該走唔甩，預計今年難到pk

想問下呢題點解私人樓又唔係打直supply curve但打斜？

Time frame 問題

呢個講緊成個政策係會長久落去，咁supply of flats not fixed

希望有卷睇

唔知聽日BAFS 2B d essay題出咩呢？

唔好出比率啊屌你hkeaa

其實都幾難答架呢d 比象我兜眼睇落去都會畫打直，btw , 應該有alternative solution掛
