想問下
Perfectly Competitive Market 有無Price Competition?
:^(

有
用price做分配資源既工具就有

教科書係寫no further price competition

其實d書可唔可以寫清楚
:^(

每年都有一問
:^(

f4個年我個miss話係冇price competition
:^(

:^(

:^(

之後問另外一個阿sir先知係有
:^(

其實想問係咪即係當producer ge output未meet到個p底下ge output個陣就有price competition. 而當meet到ge時候，因為all demand are satisfied, 所以價格(demand) 再無任何上調壓力( d人唔洗再透過價格競爭去獲取資源) , 由此先至得出個一個結論，話 no" further " price competition?

:^(
我咁理解有無錯？

:^(

你知唔知demand for individual firm in perfect competitive market係點？

係咪水平線？

:^(

有d唔明，想了解入d, 巴打可否講解

:^(

先揾OC

求解答
靜係搵到A錯
因為countryA 會出口goodX
即係good X's OC<TOT
option a: 1X=1Y >1X=0.5Y
所以錯左

:^(

係咪因為佢比左個nominal interest rate
所以就算佢actual inflation 係4%
nominal interest rate 都中係5%

:^(

本身我係咁諗
但係四個答案都唔啱
咁諗其實錯左咩

張敏 2017-4-20 19:33:44 OC: 1X=2Y
A) incorrect

Tot: 1Y=2X
Compartive advantage=Good Y

B) per gain=2Y-0.5Y=1.5Y

C) Output with trade (0,300)
Import 100X Export 50Y
Consumption with trade=(100,250)
Compare with output under self-sufficiency (100,100)
Gain: 150Y

D) Export 100Y Import 200X
Consumption with trade = ( 200,200)
Gain 100x 100y
