Printout the regression and answer each of the following questions for the regression run.

1. Evaluate this result with respect to its economic meaning, overall fit, and the signs and significance of the individual coefficients.

2. What econometric problems does this regression have?

   An omitted variable is possible; what is it?

   Deciding what to add is not easy, but if you added PROPK you should carefully review the theory behind that variable.

3. Which of the following statements comes closest to your recommendation for further action to be taken in the estimation of this equation?
   1. No specification changes are advisable (go to the next section).
   2. No variable changes are advisable, but I am concerned about heteroskedasticity or serial correlation (go to the next section).
   3. I would like to add PROPK to the equation (go to question 7).
   4. I would like to add seasonal dummies to the equation (go to question 6).
   5. I would like to change to LYDUSP from YDUSP (go to question 13).
