Suppose we are interested in measuring the relationship between log wages (variable /wage), and an individual's education level (variable educ, measured in years) and years of labor market experience (variable exper, measured in years). We estimate the following equation in STATA : Iwage=yo+yeduc+12 exper+u and get the regression output below. . reg wage educ exper Source SS df MS Number of obs = 526 F( 2, 523)= 86.86 Model Residual 111.344712 523 Total 2 18.4925198 .212896199 148.329751 525 .28253286 Prob F 0.0000 R-squared Adj R-squared = Root MSE .46141 1wage Coef.

Interpret the coefficient estimate on education. b.) What is the predicted difference in wage for a college graduate (i.e. years of education=16) versus a high school graduate (i.e. years of education=12) with the same level of experience? c.) Compute the explained sum of squares and R. Be sure to write out the formulas you use for your calculations.
