请问老师最后一列方差是如何得出

为什么降低 inflation会影响就职。降低inflation缺点是什么

右上角的swap price=(6%-5%）/2 *1 million?是这么计算的吗？去年12月考试的网课讲这道题的时候，没有除以2。

33页，从to achieve this objective开始，句式复杂，术语也多，看不懂什么意思了，请老师帮忙指点一下

原版书31页 If one argues that financial markets are not perfect, then the firm may gain some advantage from hedging its balance sheet. It may have a tax advantage, benefit from economies of scale, or have access to better information about a market than investors. 这些不太懂，资产负债表对冲是怎么给公司带来利益的呢？老师可不可以简单解释一下原理或者举个例子帮助学生理解一下

原版书31页，这段没有懂，为什么说没有人会在交易中损失？为什么零和游戏成了公平游戏？所谓的完美市场到底是什么含义呢？

老师您好，原版书中16/17页，遇到一些段落不知该如何理解，烦请老师讲一下其中的一些要领 1 But in complex portfolios of interest-rate sensitive assets, many different kinds of exposure can arise from differences in the maturities and reset dates of instruments and cash flows that are assetlike (i.e„ ´longs´) and those that are liability-like (i.e., “shorts”). 2 In particular, “curve” risk can arise in portfolios in which long and short positions of different maturities are effectively hedged against a parallel shift in yields, but not against a change in the shape of the yield curve. 3 Default risk corresponds to the debtor´s incapacity or refusal to meet his/her debt obligations, whether interest or principal payments on the loan contracted, by more than a reasonable relief period from the due date, which is usually 60 days in the banking industry.

140頁 這裡的price是沒有時間價值的對嗎

此处的A项不是最符定义的么？

139頁 還是不是很明白市場利率月看漲 看跌期權的關係，老師說的那個什麼現在有貨將來要錢，現在有錢將來換貨的例子聽不懂
