老师，第6题，B为什么不对

老师，第2题，为什么债务低的公司，市场流动性风险比较大？

老师我觉得你说的不对，opposite direction说的是相反方向，P和Q是相反方向是正效应。错是错在Veblen不是有理论支持。

R&D呢？

老师，这里不太懂…a是拒绝域面积之和，那单位的情况拒绝域就是一边啊，那为啥还要在另一边也有一个a的面积？

那个NPV是怎么求得的啊

请老师讲一下这题，没看懂

边际递减部分，对阿尔法大小的讲解与讲义内容相悖。

您好，请问这题该如何做呢？

老师好, 这是协会的练习题. 我没明白, 麻烦解释下为什么. 谢谢 Q. The maturity effect is least likely to hold for a: A. low-coupon, long-term bond trading at a discount. B. zero-coupon bond. C. low-coupon, long-term bond trading at a premium. Solution A is correct. In some situations, the maturity effect may not hold for a low-coupon bond that is trading below par. B is incorrect because the maturity effect will always hold for a zero-coupon bond. C is incorrect because the maturity effect will hold for a low-coupon bond that is trading above par.
