[回饋自修生第二擊]AL Econ答問區

[宣傳]第一擊按此[/宣傳]



如果仲有人自修econ,我都希望可以略盡棉力幫下



有咩concept唔明我可以盡量解


至於問題目答案,past paper無任歡新,past paper以外o既我未必答到你 (當然你註明出處o既話我都可能可以直接判斷有冇需要答)



拋磚引玉,出條簡單o既concept題比大家諗下:


Why, in a demand-supply diagram, the intersection point between supply and demand curves is equilibrium? Why not the other points on the diagram?


(在供需圖中,為何供應和需求曲線的交差點是均衡?為何其他圖上的點不是均衡?)

1996 AL
6.non-price competition arises when
B. transaction costs are positive and significant
C. property rights are not well-defined.
唔明點解以上情況都岩..

8. A divergence between private and social costs
B. is the consequence of market failure
C. is due to the presence of transaction costs
點解個ANS 係C而唔係B既?

9. Mr. Chan owns a taxi licence and drives his own taxi. Suppose the price of a taxi licence is increased by $50000 due to the gov't  policy to restrict the issue of taxi licences. Which is correct?
A. Mr Chan's cost of operation will increase
B. Mr. Chan will sell his taxo licence
點解ANS 係A唔係B呢?

謝謝你的幫助

1996/6
可唔可以比埋A個選擇我?(96年past paper已經冇o係手……)
C o岩好明顯
至於點解B o岩,我第一樣諗到o既係Transaction cost positive = in a society,而scarcity in a society implies competition. 不過就咁scarcity in a society並唔係只係指向non-price competition,所以我要睇埋A個答案先可以判斷點解條題目會覺得係以上皆正確

1996/8
o係AL syllabus入面,並唔同意有market failure o既存在(當然離開左AL之後咁講會比人丙)
divergence of private at social cost = at equilibrium, marginal social cost does not equal marginal social benefit
simple monopoly pricing都係一種divergence (因為MC( = marginal social cost) does not equal MUV (=marginal social benefit) at equilibrium)。咁simply monopoly pricing係唔係market failure? 你亦讀過點解simply monopoly pricing仍然係efficient,將同樣邏輯放返落去divergence到你就應該明點解正確答案係C

1996/9
cost = opportunity cost
世上選擇無處不在,而cost高唔等於唔好,因為opportunity cost高左 = 有價值高左o既機會比我放棄
自己用個的士牌o既代價係放棄將佢賣比人而得到o既錢 (因為賣比人都係一個機會)
而家的士牌個市價升左,即係賣比人所得到o既錢會高左,繼續唔賣o既話,唔賣o既代價咪升左囉
呢個純粹係rent is part of the cost個概念,咁都唔熟就要溫書啦
