关于纯粹预期理论(Pure Expectation Theory)的一些疑惑:
米什金的书讲到:
If short-term rates are high, people usually expect them to come back down. Long-term rates would then drop below short-term rates because the average of expected future short-term rates would be lower than current short-term rates and the yield curve would slope downward and become inverted.
不明白的是为什么longterm rates 会drop,是什么让它drop和 它究竟怎样影响到shortterm rate?而且说收益率曲线会倒置那就是说明longterm rate 已经drop 了,但是shortterm rate 还维持原状,为什么longterm rate 会 一下子掉下去而shortterm rate就不能使它一下子掉下去呢。
有朋友帮忙详细解释一下吗?MBA智库什么的我都看过了,我要通俗专业的解答十分感谢。
