Notes: Each cell corresponds to an estimate drawn from a different weighted least squares regression that controlled for race, sex, student SAT score, high school GPA, dummies for whether high school GPA or SAT score is missing, predicted parental income, and student athlete; the self-revelation model also controls for the average SAT score of the schools to which the student applied and for the number of applications the student submitted. Two sets of standard errors are reported, one in parentheses and one in brackets; those in brackets are robust to correlated errors among students who attended the same colleges. The top earnings category for the C&B data (more than $200,000) was topcoded at $242,662; SSA earnings data in Columns 5 and 6 were topcoded in the same way.
