Suppose you are given the following information about the default-free, coupon-paying yield curve: a) Determine the yield to maturity of a two-year zero-coupon bond. b) What is the zero-coupon yield curve for years 1 through 4. c) What is the forward rate for year 3 (short rate from end of year 2 until end of year 3). d) What should have been the zero-coupon yield for year 4 so that the forward rate in year 4 is the same than year 3
