05.单选题 已收藏 标记 纠错 A bond with a semi-annually coupon rate of 3% sells for $850. It has a modified duration of 10 and is priced at a yield to maturity (YTM) of 8.5%. If the YTM increases to 9.5%, the predicted change in price, using the duration concept decreases by: A $85.00. B $77.56. C $79.92. 查看解析 上一题 提交试卷 正确答案A 您的答案B本题平均正确率：80% Different types of Duration难度：一般 推荐：      答案解析 Approximate price change of a bond = (-)(duration)(Δy) P = -10（9.5% - 8.5%）$850 = (-0.1) ($850) = -$85 问：这里的价格为什么用原始价格，这里套公式没问题，但是问题是用哪个P搞不清楚，老师可否说的明白一些，让我好理解？

03.单选题 已收藏 标记 纠错 Which of the following statements about duration is most accurate? A Effective duration accounts for changes in a bond’s cash flows resulting from interest rate changes. B Modified duration is the most appropriate measure of interest rate sensitivity for bonds with embedded options. C Effective duration is calculated from past price changes in response to changes in yield. A 答案解析 Neither Macaulay nor modified duration is an appropriate measure of interest rate risk for bonds with embedded options. Macaulay duration does not take the current YTM into account as modified duration does. Effective duration, however, explicitly takes into account changes in a bond’s cash flows due to interest rate changes and is calculated from expected price changes in response to a given increase or decrease in yield. 问：记得不是说 effective duration是 从市场上找来的 V- 和 V+，所以为什么C说是expected cash flow，这里的现金流到底是预估的还找来的？

结构性赤字是什么意思？它的影响是？谢谢

麻烦老师解释下这题的含义，什么叫“moderate inflation”，它的影响是什么，谢谢

这题的意思是？

老师，请问一下。 资本化以后，是不是以后每年都有由于折旧摊销带来的CFI流出？ 而费用话一次性确认为CFO流出，后续几年不会有CFI流出。这么一来，in the future从第二年开始，相比于费用话，资本化的CFI流出更多，所以会有一个相对更低的CFI，那么B选项为什么不对，请老师指导！

02.单选题 已收藏 标记 纠错 Why should effective duration, rather than modified duration, be used when bonds contain embedded options? A Effective duration considers expected changes in cash flows. B Modified duration considers expected changes in cash flows. C Either could be used if the bond has embedded options. 查看解析 上一题 下一题 正确答案A 您的答案A本题平均正确率：81% Different types of Duration难度：一般 推荐：      答案解析 Modified duration assumes that the cash flows on the bond will not change (i.e., that we are dealing with non-callable bonds). This greatly differs from effective duration, which considers expected changes in cash flows that may occur for bonds with embedded options. 问：1.为什么一说到 有效久期 和 就是含权债券的关系？2.以及为什么有效久期 就和 预期现金流有关系？这里基础课感觉讲的也不太清楚，能否简单说明 有效久期的来龙去脉，至少这个久期是干嘛使的，为什么要有它呢
