List of prelim solutions corrections (*)

  • 2016 first attempt

    • The answer to 5g) should include: "Assuming the same discrete state space for A' and shocks as in the lecture notes". Briefly: If the Markov process can increase/decrease productivity by +/ 2,1 or 0 grid points. Take two firms at the lower threshold. Give one the -2 shock and the other the -1 shock. We then observe 2 different net investment rates for firms on the lower threshold. Thanks to Marco!

    • The answer to Ananth's guess and verify has a minor typo. In one of the last lines there it should be beta*rho*F*log(A)

  • 2015 first attempt

    • Some of you have reacted to the way the phase diagram is calculated. What is done is the solution is to solve for c(t+1)-c(t)=0 while being careful about that the timing. In the lectures and in the discussion section we have treated k(t+1)=k(t) when solving for c(t+1)-c(t). I think both approaches are fine, and there is no distinction in continuous time. For more, see these lecture notes by Eric Sims (as always!).
