Should the government intervene in markets?

$922.69  

Explanation:

The price of the 3-year bond can be computed using the below bond price formula:

Price=face value/(1+r)^n+coupon*(1-(1+r)^-n)/r

face value is $1000

r is the new interest rate of 8%

n is the number of annual coupons the bond would pay which is 3

coupon=face value*coupon rate=$1000*5%=$50

price=1000/(1+8%)^3+50*(1-(1+8%)^-3)/8%

price of 3-year bond=$922.69
