5. (Stock and Watson, Empirical Exercise E8.2) The data set, CPS2015, is available on Canvas. This data set contains data for fulltime, fullyear workers, ages 2534, with a high school diploma or B.A./B.S. as their highest degree. A detailed description is tiven in CPS2015_Description. In this exercise, you will investigate the relationship between a worker's age and earnings. (Gener ally order workers have more job experience, leading to higher productivity and higher earnings. a) Run a regression of average hourly earnings (AH E) on age (Age), sex (Female), and education (Bachelor). If Age increases from 25 to 26, how are earnings expected to change? If Age increases from 33 to 34, how are earnings expected to change? b) Run a regression of the log of average hourly earnings, log(AH E) on Age, Female, and Bachelor. If Age increases from 25 to 26, how are earnings expected to change? If Age increases from 33 to 34, how are earnings expected to change? 0) Run a regression of the log of average hourly earnings, log(AH E) on log(Age), Female, and Bachelor. If Age increases from 25 to 26, how are earnings expected to change? If Age increases from 33 to 34, how are earnings expected to change? (1) Run a regression of the log of average hourly earnings, log(AH E) on Age, Age2,Female, and Bachelor. If Age increases from 25 to 26, how are earnings expected to change? If Age increases from 33 to 34, how are earnings expected to change? e) Do you prefer the regression in (c) to the regression in (b)? Explain. f) Do you prefer the regression in (d) to the regression in (b)? Explain. g) Do you prefer the regression in (d) to the regression in (c)? Explain. h) Plot the regression relation between Age and log(AH E) from (b), (c), and (d) for males with a high school diploma. Describe the similarities and differences between the estimated regression functions. Would your answer change if you plotted the regression function for females with college degree? i) Run a regression of l'n.(AHE) on Age, Age2,Female, Bachelor, and the interaction term Female X Bachelor. What does the coefficient on the interaction term measure? Alexis is a 30yearold female with a bachelor's degree. What does the regression predict for her value of log(AH E)? Alexis is a 30yearold female with a bachelor's degree. What does the regression predict for her value of log(AH E)? Jane is a 30year-old female with a high school diploma. What does the regression predict for her value of log(AH E)? What is the predicted difference between Alexis's and Jane's earnings? Bob is a 30-year-old male with a bachelor's degree. What does the regression predict for his value of log(AH E)? Jim is a 30-year-old male with a high school diploma. What does the regression predict for his value of log(AH E)? What is the predicted difference between Bob's and Jim's earnings? j) Is the effect of Age on earnings different for men than for women? Specify and estimate a regression that you can use to answer this question. k) Is the effect of Age on earnings different for high school graduates than for college graduates? Specify and estimate a regression that you can use to answer this question. 1) After running all these regressions (and any others that you want to run), summarize the effect of age on earnings for young workers
