Hanson interprets Dale and Krueger

Table 4 shows that attending a college with higher SAT scores clearly lowered the wages of women 17-26 years after starting college (in 1976) – a school with a 100-point higher average SAT score reduced earnings by about 6-7%!  The two estimates there are significant at ~0.01% level! (The other three, for other periods after starting college, are significant at the 5% level.)

One obvious explanation is that women at elite colleges married richer classmate men, and so felt less need to earn money themselves. Why don’t the study’s authors want us to hear about that?

Here is much more, interesting throughout.  Robin's versatility as a commentator is one of his most underrated qualities.
