Recall that a callable bond price is equal to an equivalent non-callable bond price minus the value of the call. Add 0.001 to all of the interest rates in the tree from Part 1. Calculate the price of the callable bond in (1) using this tree. Subtract 0.001 from all of the interest rates in the tree from Part 1. Calculate the price of the callable bond in (1) using this tree. Using the callable bond prices in (1), (2), and (3), calculate the modified duration of the callable bond using Bly + Ay) Bly Ay) 1 MD 2x y B(y) Calculate the modified duration of the non-callable version of the 1.5-year bond. You should already have the prices you need for this in (1), (2), and (3). 0.020202 -0.041596 0.053025 -0.020056 0.031364 0.009932 t = 0 t = 0.5 t = 1 Using the tree from Part 1, calculate the value of a 1.5-year bond with a coupon rate of 3% (coupons paid semi-annually) that is callable at $100 at each coupon date (starting at t = 0.5) just after the coupon is paid.
