可唔可以講下咩係balance of payment?
點解increase in foreign exchange reserve assets 係金額增加/有BoP deficit?

BoP surplus => ORA increase

BoP = ca + ka

ka係 購買及增持外地資產 - 售賣及減持外地資產。 foreign exchange係外地資產 所以 increase foreign exchange會 increase ka , suppose ca remain unchanged, 咁Bop就會有deficit

Sor off topic
有個問題困擾左我好耐求解答
當D升 P升Q升
TSS一定升啦
PS都一定升
咁到底CS自己既change 係升定uncertain

嘗試自問自答
我嘗試用兩個extreme case去諗 如果perfectly inelastic supply
D升 P升 Q不變 從面積黎睇CS升同跌係一樣既 所以話CS不變
如果perfectly elastic supply
D升 P不變 Q升 咁就只有CS升冇跌既area
可唔可以咁樣論證中間既case都係increase in CS > decrease in CS ? (因為最extreme 既case CS都係不變 唔會跌)
我知我討論既野都係out out 地 syl 不過我真係好想得到解答

應該係uncertain

屌做cliff mc仲係錯緊6-7條，點撚算

BoP surplus => ORA increase

咩係ORA?
點解BOP surplus, government foreign asset reserve會增加?

cliff yeung's mock

小弟又有問題
而家溫到money 果度

想問第29條
點解又會郁reserve?
睇左herman yeung 佢講就講其實唔會郁reserve但做就成日都郁
我好亂
救下我 想拎個3 淨番時間全力溫econ

$200 million newly printed banknotes
$100 million 由non-bank public keep
另外$100 million will be kept as reserves in the banking system

Btw答lq成日答唔到marking，concept都ok清
巴打我可以點改
係咪logic問題

Logic太快唔夠仔細，每寫一個step問下自己: 跟住會點，你逐步逐步諗，將Flow寫翻出黎。試下真係係個心問自己。

sorry發緊夢，當無睇過😂, 應該係surplus先真

ka係 購買及增持外地資產 - 售賣及減持外地資產。 foreign exchange係外地資產 所以 increase foreign exchange會 increase ka , suppose ca remain unchanged, 咁Bop就會有deficit

點解CA positive , KA一定negative?
For example :
有trade surplus
D錢唔一定要洗係外地資產度架
可以save底唔用/只買本地野

同埋capital inflow-capital outflow=Ka? (咁Ka係咪包埋reserve asset? )

你要明deposit creation concept
假設銀行本身唔可以loan, banking system而家有:
Reserve: 100
Loan: 0
Deposit: 100

跟住而家有個fractional reserve scheme, (R/D)>/=20%，姐係rrr=20%，咁有銀行loan out, in banking system:
Reserve: 20
Loan: 80
Deposit: 100

Then money redeposited into banking system,
Reserve: 100
Loan: 80
Deposit: 180

And then banks lend out again:
Reserve: 100-64
Loan: 80+64
Deposit: 180

Then redeposit
Reserve: 100
Loan: 144
Deposit: 244

咁你個deposit既數係:
100+100(1-rrr)+100(1-rrr)^2... -(a)
呢個就係math core 既GS sum to infinity
So, (a)=100/(1-(1-rrr)=100*(1/rrr)

冇睇你題目 但trade balance=x-m
同saving/只買本地野好似冇乜關係
CA+KA=0 因為bop計埋ora一定係balanced 所以會係一正一反

呢樣可以用一條identity分析，上年out左syl

Y=C+I+G+NX
Y-C-G=I+NX
Sn-I=NX

If Sn>I => NX>0

Further assume that net current transfer, net factor income from abroad = 0
CA=NX
Sn-I=CA

If Sn>I => CA>0 (save多過你invest就去買foreign goods)

Therefore CA>0, KFA<0 (accquired foreign asset)

CA=-KFA

KFA包左ORA
