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?

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
