Consider the equation below that gives interest rate dynamics in a setting where the time axis [0, T] is subdivided into it equal intervals, each of length ?:rt+? = rt + αrt + σt(Wt+? - Wt) + σ2(Wt - Wt-?)where the random error terms?Wt = (Wt+? - Wt) are distributed normally as?Wt ≈ N (0,√(?)).(a) Explain the structure of the error terms in this equation. In particular, do you find it plausible that ?Wt-? may enter the dynamics of observed interest rates?(b) Can you write a stochastic differential equation that will be the analog of this in continuous time? What is the difficulty?(e) Now suppose you know, in addition, that long-term interest rates, R, move according to a dynamic given byRt+? = Rt + βrt + θ1(Wt+? - Wt) + θ2(Wt - Wt-?),where we also know the covariance:E[?W?W] = ρ?.Can you write a representation for the vector processsuch that Xt is a first-order Markov?(d) Can you write a continuous lime equivalent of this system?(e) Suppose short or long rates are individually non-Markov. Is it possible that they are jointlyso?
