老师好,原版书P741-P742, 这两张截图我有些地方不明白。1 公式10,11 → 这两个公式,我没看懂 2 原版书 中说 :“ If the output-to-capital ratio is above its equilibrium level (ψ), the second term in Equations 10 and 11 is positive and the growth rates of output per capita and the capital-to-labor ratio are above the steady state rate [θ/(1 – α)]. This corresponds to a situation in which actual saving/investment exceeds required investment and abovetrend growth in per capita output is driven by an above-trend rate of capital deepening. This situation usually reflects a relatively low capital-to-labor ratio but could, at least in principle, arise from high TFP. Because α < 1, capital is growing faster than output and the output-to-capital ratio is falling. Over time, the growth rates of both output per capita and the capital-to-labor ratio decline to the steady state rate. 这一整段,我不是非常明白,麻烦给解释一下。多谢!
老师好,原版书P740中,这个depreciation rate 是什么呢? 为什么depreciation rate的提高会降低capital-to-labor, 降低output-per-worker, 而提高steady state growth rate?
还有对衍生品,我理解不深刻,例如签订FRA,LONG的一方,多头方,将来可以以固定利率借款,收到浮动利率。这里签订未来固定利率,锁定它,给固定利息容易理解,那为什么还收浮动利率利息呢,我来借钱,怕利率涨了,就签一个未来固定利率 那我就未来给固定利息就完事了,还收什么利息呢,有钱收利息,我还借什么钱呢,同理对于空头方。

- Growth due to capital deepening 是αΔK/K还是ΔK/K
- 请老师讲解一下这个题目
- 老师,第三题答案的意思是:1.因为宽松的货币政策,导致加元利率下跌,导致加元贬值?2.但是,如果利率下跌,也就是分母上的百分比下降,不是会导致价格上升吗?。3.从而短期看是depreciation,但是长期来看,会回归到均值,所以是appreciation?
- 很迷惑到底是long call+ short stock还是long stock+short call构建无风险资产
- 这道题可不可以用算出来的fpa除以0.9算出的价格和125比较,得出的差额是套利的利润?
- 不太明白为什么AI0 20 加上后 后面AIT 是减50, 为什么要重复计算0~T=2 这段的coupon?
- 第4题 讲义没有讲到,能在详细讲一下吗
- 这题为什么是选C?
