Document Summary

Now we understand the intuition for how the data should be used. What do we do to statistically confirm the real beer tax effect on fatality. If z were a control variable then it will be a specific regressor and it would be z it. We know that z i is an omitted variable causing trouble, but once you control it then there are no more ovb. Subtract 1988 from 1982 -> you have the difference in fatality rates which is a function of difference in beer tax (same slope) Initial population regression, have already assumed that it"s the true population regression line in slide 12 - regardless of dataset, assume that impact of beer tax will be beta 1. Assume that constant effect of beer tax, hence why beta 1 is constant throughout the years. Divide throughout 2 regressions, you have same beta 0, beta 1, beta 2. Run regression on differences, still estimate same beta 1.
