Problem 1Let P(YTM) denote the bond pricing equation for perpetual, zero-coupon, and coupon paying bonds as afunction of the yield-to-maturity (YTM).Perpetual bonds: P(YTM_p)= C/YTM_pZero-coupon bonds: P(YTM_a)= F/(1+YTM_a)mCoupon-paying bonds: P(YTM_p)= C/(1+YTM_p)1+ C/(1+YTM_p)2+...+ C/(1+YTM_p)2m + F/(1+YTM_p)2mWhere, C is the coupon, m is maturity in years, YTM_p is the periodic (semi-annual) YTM, YTM_a is the annual YTM. For all types of bonds:a) Calculate the first derivative of the pricing function, dP(YTM)/dYTMb) Calculate the second derivative of the pricing function, d2P(YTM)/dYTM2c) Calculate the Modified Duration, MD =-(1/P) x dP(YTM)/dYTMd) Calculate the Duration, D = MD x (1+YTM)e) Calculate the Convexity, Conv =(1/P) x d2P(YTM)/dYTM2Problem 2Based on the duration and convexity formulas you found in Problem 1, derive the change in bond prices (Price) for perpetual, zero-coupon, and coupon paying bonds as a linear approximation of thea) Modified Durationb) Durationc) Modified Duration and Convexityd) Duration and Convexity
