老师好，请问原版书P737这个公式 9 需要记吗？ 还要除以saving rate....之前视频里老师都没有讲过这个公式啊....

在老师的讲解中，老师提到统计局的图表应注明出处，但Notes第21页提到crediting the source is not required when using tables from recognized financial and statistical reporting services,而课后练习第3题也延续了这一观点(他们认为正确答案为C)，请问以谁的观点为准？

那put call 哪个更凸

老师 她这个建议给了all clients？不是没有产品适合全部人吗

您好，想问一下最后一句，说两者差别的，汇率的影响是指unrealied还是realized gain or loss啊？因为我之前自己记得notes写的是，对于unrealized gain or sale available for sale在IRFS必须是汇率引起的，GAAP无所谓，所以我不太确定，您能不能看看我之前记得notes和截图中说的意思一样吗？谢谢！

老师 labor productivity 和 per capita output是不是都是指 Y/L=y ?

再投资风险主导时 为什么利率下降 风险更大

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！

老师补充一下 clean price和full price的计算 我找不到

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?
