徐同學(xué)你好,這句話是原版書P386頁的原話,這句話來自于一個大case的中間部分,所在把他放在這里可能會覺得有點突兀。
這句話大體的意思是說,我投資者會買更多債券,我有很多債券,那未來的收入會更高,邊際效用會更低,我未來已經(jīng)有很多錢了,我就沒那么有動力想要更多債券了,所以導(dǎo)致投資者投資于無風(fēng)險資產(chǎn)的邊際意愿下降。除非當(dāng)許多投資者愿意以9,544.98美元交易時,市場價格才會上漲(需求大,價格就會上漲),直到所有投資者都有相同的邊際投資意愿。

In Example 1, suppose the current market price of the real default-free bond is $9,540 per $10,000, but the investor’s inter-temporal rate of substitution is $0.954498 per one dollar promised. The investor would then value the guarantee of $10,000 in one period more than the market, so she would purchase it. As she buys more of the bond, her future income is higher and its marginal utility lower, leading to a fall in her marginal willingness to invest in the risk-free asset. Only if there are many investors with the willingness to trade at $9,544.98 would the market price increase until all investors have the same marginal willingness to invest

那是不是這兩句話并沒有必然聯(lián)系,我分開理解就好了?

徐同學(xué)你好,
他是有聯(lián)系的,按這個Case的邏輯來,這個事情是說的通的。
