Raj Chetty, a professor of economics at Harvard, in 2010 published a study that estimates that having an above - average kindergarten teacher in a classroom of 20 will generate about $ 320,000 more in
total lifetime earnings for each of his or her students, compared to the same class with a below - average teacher.
Using the corrected values for STEM in Table 8, we see that the college premium for STEM majors has increased by about 27 % from the first cohort to the last — a significantly larger increase than the 14 % reported above in the growth of
total lifetime earnings.
So it would not be unusual for a Harvard MBA to earn another $ 3.2 million during those years to bring
total lifetime earnings after the MBA to something approaching $ 6.5 million.
