4. if there is a technology breakthrough is improved, does it mean the supply will increase?

i think is no.

If the supply of good A increase, then the competitive supply of good A will drop.

Just think

i think is no.

.......

If the increased supply can induce a increase in revenue
then the supply will increase
so all depends on the elasticity of demand
the answer is no (not sure)

咩黎架 =.= ?

我就覺得第4題因為有technology breakthrough, cost of production is reduced,
假設, 用黎produce果筆錢不變的話, supply咪多左囉

的確有potential 去increase supply
但若果demand 係inelastic
increased supply 所帶黎o既decrease in price 只會做成損失
supply curve 係the quantity supply that the firm is willing and able to produce at each price level

注意able to produce 並不代表willing to produce

我假設左elasticity of demand 係 1丫嘛 (holding other things being constant)

the ans is: 1.c 2.b 3.b (in fact (1)and (2) is the condition of q.3)
4.the supply increase
5. raise quota=more import is allowed(think this sentence in chinese)
6. c

i find the ans but don't know y , can any1 explain?

especially for no.6, how to find the revenue after tax?
and how to compare the original revenue and new revenue to determine whether the revenue after tax increase/decrease?

第三題係因為(2)呢個condition入面只係因為價錢升左只會令到quantity supplied升,唔會令supply升

第一同第二題好似會考出過....owning同living呢兩個字有分別...我記得阿sir講過,live唔代表own..所以cost係forgive renting out the house...own既cost就係放棄賣出去既$,而d$可以擺係銀行到收利息,假設無限咁收,同返0個條計無限既公式,就可以得出答案

d. there is no opportunity cost because he lives in his own house.


唔太識英文

不過呢題重點你要記得機會成本既公式
同埋睇清楚month同years
