Given the following regression:

wagei = β0 + β1edui + β2experi + β3exper2i + β4exper3i + ui

wagei = -4.146156 + .5959117edui + .3191707experi - .0074834exper2i + .0000415exper3i + ui

Which order of polynomial (i.e., J) best describes the relationship between work experience and wages? Please explain your answer.

Using your model above), what is the marginal effect of experience when experience increases from 9 to 10 years? What is the marginal effect of experience when experience increases from 25 to 26 years? Does experience exhibit diminishing marginal returns?

Using your model above, find the average difference in wages between someone with 15 years of experience and someone with 23 years of experience, holding education constant. Is the difference statistically significant?

Suppose you estimate the following regression model using OLS: Yi = β0 + β1Xi + β2Xi2 + β3Xi3+ ui. You estimate that the p-value of the F-test that β2= β3 =0 is 0.01. This implies: options: You can reject the null hypothesis that the regression function is linear. You cannot reject the null hypothesis that the regression function is either quadratic or cubic. The alternate hypothesis is that the regression function is either quadratic or cubic. Both (a) and (c).
