ECONOMETRICS I Winter 2014 PROBLEM SET 1 This assignment is due on Tuesday, January 21st , at the beginning of the practice session at 8:15 am. Late solutions are not accepted. Exercises: 1. (1 pt) BH Exercise 2.18. 2. (1 pt) BH Exercise 3.3. 3. (1 pt) BH Exercise 3.6. Let yˆ = X(X 0 X)−1 X 0 y. Find the OLS coefficient from a regression of yˆ on X. Additionally, compare it to the OLS coefficient from a regression of y on X. 4. (1 pt) BH Exercise 3.11. 5. (2 pt) BH Exercise 3.19 - MATLAB (STATA or R). • Note: In part (2), even though it is not explicitly stated, I would request that, when examining the residual regression approach, you regress both log(W age) and education on experience, experience-squared and a constant. • Additionally, please provide an interpretation of the coefficient on education and a short discussion of whether such an interpretation contains much merit. 6. (2 pt) BH Exercise 3.20 - MATLAB (STATA or R). 7. (2 pt) BH Exercise 3.13. P.S. BH stands for the Bruce Hansen’s Econometrics manuscript.
