Why marrying your equal can boost inequality

(Continued)

WASHINGTON —

Finally, marital sorting may be having some effect on geographical mobility. Cross-state mobility rates have been falling in the United States, research by Raven Molloy and Christopher Smith of the Federal Reserve and Abigail Wozniak of the University of Notre Dame has found.

In my role on the boards of nonprofits, I have seen many job offers declined because a move would be required, and the person's spouse would have to leave behind a promising career. Because finding two good jobs in a new city is much harder than finding just one, is it possible that this "co-location problem" for dual-earning couples with increasingly similar incomes and educational backgrounds is discouraging mobility?

Well-educated couples tend to live in large cities because it increases the chance that both spouses can find an adequate job, research by Dora Costa of the Massachusetts Institute of Technology and Matthew Kahn of the University of California at Los Angeles suggests. Another piece of evidence comes from the cross-state mobility rates themselves. Since the 1980s, they have fallen almost by half among dual-earning couples, while the rate for single (or no) earners has fallen by only a third. Yet Molloy finds some evidence that these differential trends have had only a modest effect on total mobility rates (after other factors are taken into account).

In any case, assortative mating indicates why trying to bridge the increasing divides between rich and poor in the U.S. is so complicated and difficult. If income inequality is being driven in part by changes in marriage patterns, what can anyone do about that?

    Taylor Swift, the seven-time Grammy winner, is known for her articulate lyrics, so there was nothing surprising about her writing a long column for The Wall Street Journal about the future of the music industry. Yet there's reason to doubt the optimism of what she had to say.

  • The science of shyness

    Shy people have quite a bit to contend with - not least the word itself. It has a number of different meanings, none of which are flattering. To "shy away" from something implies avoidance; to "shy" can also mean to move suddenly in fright; to "be shy of" something can mean to come up short, or be insufficient.

  • Wanna write a pop song? Here's a foolproof equation

    Pop songs (generally) stay in one key, are in 4/4 time, last between three and five minutes, are organized into chunks of four or eight bars, have a repeating chorus played two to four times, include the title sung at least three times, and feature short melodic fragments that repeat a lot to help everyone to remember them.
