Just as politics often trumps economics when it comes to public policy, rational arguments rarely win the day in dating, love, and marriage.
I wouldn’t expect male economists to marry very well. Firstly, they tend to think like the guy who wrote this letter. Secondly, they tend to be nerds. Thirdly, they make very little money when they are young because they get so much education, even though their lifetime income is quite high. Yet I think it is fair to say that the economists I know have married stunningly well (myself included). We’ve all been puzzling over this fact for the fifteen years I have been in the profession. As of yet, no one has come up with a good explanation. I doubt it could be perfect foresight on the part of the women we marry.
Also, completely contrary to what an economic model might predict, I can’t think of any economist who left his wife in middle age for a younger “trophy” wife. There must be cases, but none that spring to mind.
So maybe economists aren’t such heartless, conniving people after all. Or maybe economists just care so little about human relationships that it’s not worth the trouble to try to acquire a trophy wife.
--Steve Levitt, Freakonomics blog, on male economists in the marriage market. Actually, I can think of one middle-aged economist with a decades younger, very beautiful wife, although I don't know if he left another wife for her.
