What happens when you apply cold economic principles to heated marital problems? According to the authors of Spousonomics: Using Economics to Master Love, Marriage, and Dirty Dishes, you get logical solutions that work for everything from resolving quarrels in the kitchen to a lack of activity in the bedroom. “Spousonomics doesn’t require you to keep an anger log, a courage journal, or a feelings calendar,” write the authors, Paula Szuchman and Jenny Anderson, who have covered financial meltdowns and interviewed economic heavyweights like Tim Geithner and Hank Paulson for The Wall Street Journal and The New York Times.
Spousonomics, they say, is about using time-tested theories like Adam Smith’s idea that businesses thrive when employees have specialized tasks, and then applying that to fight-prone areas of marriage such as housekeeping and tending to the kids. But how should a couple decide who is best suited to the tasks of laundry and vacuuming? For answers on that, the authors turned to British economist David Ricardo’s theory of “comparative advantage,” which, as the authors explain it, suggests “it’s not efficient for you to take on every single task you’re good at, only those tasks you’re relatively better at compared to other tasks.”
To show how it works at home, the authors present Eric and Nancy, “a case study in how a bad division of labour can harm an otherwise well-matched couple.” It used to be that Eric and Nancy split household chores strictly 50-50, and not according to who did which job best. If Eric cooked dinner one night, Nancy cooked the next night. The trouble was, “everything was a debate,” says Nancy. If Eric was chopping onions for the lamb tajine, for instance, he’d boil over at seeing Nancy sitting watching Law & Order. “Wait a minute,” he’d think, “why am I spending all this time on a fancy meal when all she ever makes is mac and cheese?”
“We spent so much time fighting over who was doing more, it’s amazing we got anything done at all,” says Nancy. Eric agreed. “I knew we’d have to stop keeping score,” he said, and so they started dividing things according to comparative advantage.
First, they made a list of chores. Then they wrote down how much time each chore took. For instance, tidying up took Nancy 10 minutes; it took Eric 60. Doing the dishes took Nancy 20 minutes; it took Eric 30.
Nancy is faster at both tidying and dishes but she is comparatively much faster at tidying than Eric. Therefore, according to Ricardo’s theory, Nancy should always do all the tidying up and Eric should always do all the dishes. The new system saves Nancy 30 minutes of her time each week, and saves Eric 90 minutes.
