Consider a bond with annual coupon rate = 7%, yield to maturity = 5%, time to maturity = 3 years, and face value = $200. Coupons are paid semiannually. Calculate the price of the bond. Calculate the modified duration of the bond. Calculate the convexity measure of the bond. When yield to maturity increases by 2 percent, calculate the approximate percentage change in bond price based on the modified duration and the convexity measure of the bond.
