The midterm exams have been graded. You may pick up your blue books and an answer sheet from Diane Bowman in 28 Hillhouse. The mean score was 47.1 and the standard deviation of the scores was 11.8. The CDF of the scores is available from Ms. Bowman and is posted outside Sims' office and Hall's office. Grading will be discussed briefly in class on Thursday.

Answers to mid-term exam: (pdf

earlier in printed form. It may not look readable on your screen,
but it will print out cleanly. Answers to 2 and 3 that are more readable
on the screen are posted separately: (pdf

Two Matlab programs that solve the optimal growth model will be discussed in class on 2/4/99. These programs are det_dp.m and stoch_dp.m.

Answer to Exercise Due 1/28, plus notes on simplified transversality conditions(pdf file, 68k)

- Though the general TVC in the "Random
Lagrange Multipliers" notes covers a wide range of non-standard models,
it is complicated to check and hard to remember. By restricting the
range of models considered, we can simplify it.
