问一道题:NO.PZ2015120204000023

问题如下:

\(\begin{array}{l}Excess\text{ }stock\text{ }market\text{ }return_t\\=a_0+a_1Default\text{ }spread_{t-1}\text{ }+a_2Term\text{ }spread_{t-1}\text{ }+a_3Pres\text{ }party\text{ }dummy_{t-1}\text{ }+e\end{array}\)

Default spread is equal to the yield on Baa bonds minus the yield on Aaa bonds. Term spread is equal to the yield on a 10-year constant-maturity US Treasury index minus the yield on a 1-year constant-maturity US Treasury index. Pres party dummy is equal to 1 if the US President is a member of the Democratic Party and 0 if a member of the Republican Party.

The regression is estimated with 431 observations.

Exhibit 1.Multiple Regression Output

With respect to the default spread, the estimated model indicates that when business conditions are:

选项:

A.

strong, expected excess returns will be higher.

B.

weak, expected excess returns will be lower.

C.

weak, expected excess returns will be higher.

解释:

C is correct.

The default spread is typically larger when business conditions are poor, i.e., a greater probability of default by the borrower. The positive sign for default spread (see Exhibit 1) indicates that expected returns are positively related to default spreads, meaning that excess returns are greater when business conditions are poor.

NO.PZ2015120204000023 老师 从直观的经济层面去理解 是没问题的 但是从题意去看 a1是正的 说明自变量和因变量是正相关 不应该选C啊?

NO.PZ2015120204000023 老师好,在这个题目里面还提到了t-statistic和p-value,这是代表什么意思呢?对这个题目的分析判断有影响吗?谢谢

NO.PZ2015120204000023 The positive sign for fault spre(see Exhibit 1) incates thexpectereturns are positively relateto fault sprea, meaning thexcess returns are greater when business contions are poor. 老师好,关于解析中的这句话,前半句我理解的,因为coefficient是正数,所以正相关。但是为何正相关就可以推导出“excess returns are greater when business contions are poor.”呢?是从这个公式里面看出来的吗?谢谢

请问,经济条件不好的时候fault sprea大大是不是和下面的表述矛盾了fault spreis equto the yielon Bbon minus the yielon Abon. 经济不好的时候Abon的yiel是更大么?那yielon Bbon-yielon Abon不是变小了么?
