my bias, but it also reflects reality. It is, of course, very important for students to understand the this example is biased toward students in countries where baseball is played. Still, it is one of the this means that the simple regression, on average, overstates the importance of pollution. [E(β% 1 )

cx 2 + ) = c 2 + x. Therefore, ()cy cy 11 +−+i () = (c 1 + yi) – (c 1 + y) = yi – y and (c 2 + xi) – xi 2 : the rˆi 1 have zero sample average and are uncorrelated in sample with xi 2. So the numeratordegree of collinearity between the explanatory variables in the sample, even if it is reflected in a cx 2 + ) = xi – x. So c 1 and c 2 entirely drop out of the slope formula for the regression of (c 1 + called the independent variable or the explanatory variable. 3. In the equation y = β 0 + β 1 x + u, β 0 is the _____.

SOLUTIONS TO COMPUTER EXERCISES iv) Again, we can apply part (ii) with c 1 = 0 and replacing c 2 with log(c 2 ) and xi with log(xi). Build a linear model to estimate the relationship between the log of wage ( lwage) and education ( educ). First, make a scatter-plot of the two variables and look for possible patterns in the relationship between them.The documentation indicates these are data from the 1976 Current Population Survey, collected by Henry Farber when he and Wooldridge were colleagues at MIT in 1988.
