Expectation呢樣野課課都出得，分好d expected change 同 change
想問下option a 同b有咩分別？
點解option b 唔會令到md下降？
A expectation = 啲人想賺錢去invest bond
B = 貴左唔會有incentive 去特別買

求解依課一向麻麻地 諗唔明 :^(想有個詳細嘅logic flow 唔該哂 :^(
1. 搵equilibrium
Qd = Qs = 3 units at P=120
2. Effective Price Floor?
Yes, Pf = 130 > 120
3. Consumer Surplus
New CS = 10
Old CS = 20+10 = 30
4. Producer Surplus
New PS = 30+20=50
5. TSS new = CS+PS = 60

依兩part係點計出黎？邊個數減邊個數？
20 10 30同20依幾個數
同埋另外一位巴打講可以用(140-100)+(130-110)嘅方法計tss 兩個brackets係分別計緊cs and ps定點？

其實兩課al都有，大學econ course更加教ppf先，
我諗係好多人搞唔到OC個d
阻一阻各位
我而家中五，希望下年dse econ有5*
校內試基本上徘徊係六至七十分
學校take elective1
想問下各位:
點解上面咁多巴打recommend e2?兩者有咩分別？
另外而家仲有一年時間嚟講各位建議我點溫？自己睇？報補習？
最後我本教科書都係用緊Pearson想知有咩好大嘅問題？ :^(
最後祝呢個post嘅巴絲考到自己想要嘅分數啦
e1比起e2多好多野背
好似係咁
我自己溫落都覺得anti competitive behaviour有好多嘢要背
等我睇下e2係點先
多謝巴打
E1 好多野背
E2 一識左concept就條條都滿分
寫既野又少 你睇返2015個條 畫條線 plot一點就3分
咁巴打覺得學校教e1嘅原因係乜
會唔會係e2個concept較難掌握？
因為之前教開a level?
我老師確實係有教al

Original equilibrium price原本均衡價格 = $120
Price floor 價格下限 = $130
=> Effective Price floor 有效價格下限
而家交易量= 2 unit
咁TSS = summation(MB-MC)，我地知MB=D, MC=S
TSS = (140-100) + (130-110)= $60
有巴打提到用三角形，其實出得最準既題目係逐個Q加上去，你係唔會用三角形。三角形係Q唔係逐個上，同堆有講係linear demand curve/比左圖你先會用（數學concept黎）。
你見到坊間題目唔係咁就係出得唔好。
