请教几道金融学方面的题目（英）,
1.consider three bonds with 8 coupon rates all selling at face value,the shot-term bonds has a maturity of 4 years,the intermediate-term bonds have maturity 8 years,and the long-term bonds have maturity 30 years,
(1)what will happen to the price of each bond if their yields increase to 9%?
(2)what do you conclude about the relationship between time to maturity and the sensitivity of bond prices to interest rates?

Answer 1

1.their prices will all decrease as yields increased to 9%.随着折现率上升 债券价格下降
2.the longer the time to maturity,the more sensitive the bond price respect to interest rate.TTM越长 债券价格对折现率变动的敏感度越高
