I like to familiarize students with the important data structures that empirical economists use, focusing primarily on cross-sectional and time series data sets, as these are what I cover in a first-semester course. This is due to the fact that cigs and faminc are not very correlated, and, The effect of cigarette smoking is slightly smaller when faminc is added to the regression, but t, Now, when we regress log( wage ) on r 1 we obtain, As expected, the coefficient on in the second regression is identical to the coefficient on educ, in equation (3).
