新手po文請多指教
小弟在讀James Tobin的貨幣需求的資產組合理論時
發生了一個問題:
Gordon:Tobin's approach does not explain why anyone holds
currency or non-interest-bearing checking accounts
when safe, interest-bearing assets are available.
Mankiw:portfolio theories cannot explain the damand for
these dominated forms of money.
以上,我想問的是:
Tobin不就是說因為moeny可以分散風險,所以投資者才會將money納入
資產組合裡面.
那為什麼以上兩人會說資產組合理論不能解釋當有其它更
具價值(有報酬)的資產時,投資者還會將money(劣勢資產)納入組合裡.
阿不就是因為money可以分散風險嗎?
並且~
Mankiw還說該理論不適合於當money是限制於M1時的情形,若是限定在
M2,M3則非常合理.
請教各位版大~
謝謝!
