e2個條OC before trade唔係玩silmilar triangle計數啊嘛

應該唔洗用similar triangle
可以好正常咁計到

我無咁癡線

有冇得派答案先 做完好想對

我都覺得好似太耐，今晚起好佢

定係你想要呢條個ans？

麻煩了

做完條e2 唔知啱唔啱

計黎計去都計到C(and PS remains unchanged) 但答案係B 求指點

有冇睇到average cost
Ps未睇晒題目

計左d total cost, marginal cost 先啦

做個時計哂啦
when q=13(mc=p=50) tv=650 tc=338 fc=156 profit=312 ps=468
when q=12(mc=p=46) tv=552 tc=288 fc=204 profit=264 ps=468
profit=tv-tv
ps=profit+fc
唔知錯係邊

點解比sme subsidies可以alleviate inflation 我理解係sme攞左筆錢去invest/expand the business都會令到I升 繼而AD升 P升

Sras升 p跌

係喎屌
所以當sras升>ad升嘅時候 p就會跌 咁理解有冇錯

同ps=profit+fc條式好似係冇分別
都係計到468 for both cases

想問係咩情況下actual real rate of return of holding bond會係negative?
我自己理解係actual inflation rate higher than the expected inflation rate
答案係actual inflation rate higher than the nominal interest rate
當然都合理 但我嘅理解邊到出錯
有咩情況下 actual inflation rate<expected inflation rate 但都都可以令到real interest rate係負數？
（PS 我係係nominal interest rate同expected real interest rate都要>0嘅理解基礎上去諗）

例如
nominal interest rate=actual interest rate+expected inflation rate
5=2+3
但係最後actual inflation rate係5
咁會變成5=0+5
actual 會唔係負數
所以我估你個諗法會諗漏咗呢個case

咁0就變左唔符合依個條件

R=r+π(e) => r=R-π(e)

If turns out R-π < 0, r<0
Therefore r<0 when R<π

R=r+π(e) => r=R-π(e)

If turns out R-π < 0, r(actual)<0
Therefore r(actual)<0 when R<π(actual)

Your answer:
π(e)<π
We can only know r(decided)<r(actual)
