问题如下：
What impact would a “flight to safety” (i.e., government bond yields falling and credit spreads widening) have on the analytical duration estimate of Bond A?
选项：
A.
Decreased duration
B.
Increased duration
C.
No impact
解释：
C is correct. There would be no impact on the analytical duration estimate. However, an empirical duration estimate would be impacted. A flight to safety would result in an increase in the bond price due to the falling benchmark yield being offset by widening credit spread. This would lead to a lower empirical duration than analytical duration.
