As an illustrative hypothetical, imagine an average student (GPA 3.25‐3.5) at 47th ranked University of Florida. Using the fifth column from Table 11 (AJD regressions on salary), we can predict how her earnings would be affected under various counterfactuals. If she had attended 20th ranked George Washington University, her grades likely would have slipped to the 2.75‐3.0 range, and her salary would drop considerably (by 22%, all other factors held constant.) Even if she had managed to get a spot at 7th ranked UC Berkeley, where the tier premiums are highest, her grades likely would have fallen into the 2.5‐2.75 range, and her salary would be 7% lower. On the other hand, if she had attended 80th ranked Rutgers, she probably could have improved her grades to land in the 3.5‐3.75 range, and earned a 13% higher salary.
