Question 2 (80 points) Consider the following model for the mean and volatility of asset returns: rt = Et = Bht tet hut ht u* + 0167-1 + $767-2 +0367-3 Et1(ut) = 0 and Et-1(u) = 1 = = 1. (30 point) What is the conditional expectation Et-1(rt)? Show your derivations. 2. (30 point) What is the conditional variance Vt-1(rt)? Show your derivations. 3. (20 point) What is the unconditional expectation E(rt)? Show your derivations.
