Suppose that the spot rates st=3% for t10 years (on a continuously compounded basis), and suppose that the forward rates f10,t=5% for t>10 years (continuously componded), i.e. all forward rates starting from 10 years are 5%. (a) For t>10 years, what is the forward discount factor d10,t ? (Hint: Use the forward rate) (b) Using part (a), for t>10 years, what is the discount factor dt
