"Does marrying someone with less education mean “marrying down” economically? Not necessarily. When we look at the newlywed women who married someone with less education, we find that a majority of these women actually “married up.” In 2012, only 39% of newlywed women who married a spouse with less education out-earned their husband, and a majority of them (58%) made less than their husband."

Not really that surprising. Irrespective of gender, a terminal degree rarely leads to increase job earnings except for MD, JD, MBA, and similar.

Right, my interpretation of other comments about education, was that women were marrying down based on education level. But economically this isn't true. They still marry up.

I'd be surprised if degree level was a major factor by itself. E.g. If the woman has a masters but the man has only a bachelors, she would discount the man as a potential mate. He may still be socioeconomically on par or better.
