你本身畫個Demand supply graph就係assume左係perfectly competitive market
price就緊係會轉

Market revenue curve 打橫即係點?

Rival: one consumption will reduce availability for others to consune
Excludable: can exclude those who do not paid from consuming the goods in low cost

Paper 1 MCQ
1. 一分鐘一條,唔好停係一條太耐,要留10分鐘check卷。
2. 今日睇翻做過既題目,唔好再做太多新野。
3. 唔識既就試排除法
4. 睇清楚NOT true
5. 留意題目提問用字,MUST(必然)係要向反證既方向諗,諗下們會唔會錯。MAY(可能)你係要指出佢可能不,諗有無一個情況佢會岩。呢d字撈亂就會錯。
6. 題目可能有錯,揀最佳答案。
7. 今年應該會再少d直接問definition既題目。
8. Elasticity 彈性小心睇,係計緊demand 定supply係睇你move along邊條curve,不是你shift 個條。
9. 睇清楚Average(平均)/Marginal(邊際)/Total(總)
10. Classical QTM=LR QTM (上年一班人唔識)
11. Positive statement實證陳述係要refutable by facts(可被事實推翻),而唔係要正確。錯既statement(e.g. 我放手既枝筆會向上飛)都可以係實證。
12. 唔好複雜化條題目,推理用正常方式做,有時intuition 好重要。
13. GDP睇清楚d components,有時係net(淨),有時係total(總),Investment Expenditures 都要睇清楚。
