We are going to analyze the effect of the yield to maturity on the duration of the bond. Compute the duration of a bond with a face value of $1,000, a coupon rate of 7% (coupon is paid annually) and a maturity of 10 yearsas the interest rate (or yield to maturity) on the bond changes from 2% to 12% (consider increments of 1% - so you need to compute the duration for various yields to maturity 2%, 3%, ..., 12%) . What happens to duration as the interest rate increases?
