Consider the risk-neutral Ho-Lee model for continuously compounded rates for t = 0,1,2 and a step size of A-0.25 year (today is denoted by time 0): To=0,03 71-70+ 0.01+0.02 € 72 71 +0.015+0.02 where, under the risk-neutral measure, the shocks (t = 1,2), which are independent and identically distributed, are given by {# -1 +1 with probability 0.5 with probability 0.5 1. [5 points] What is the price of a 9-month non-callable bond with principal 100 and an annual coupon rate of 8%? (To be precise, the coupons are paid at times t = 1, 2, 3, quarterly; while the principal repayment is at time t = 3). 2. [8 points] Now suppose that the above bond is callable. What is the value of the callable bond? What is the value of the implicit call option? In which nodes will the bond be called (assume no call option initially)? 3.
