Economics of Marrying for Money

Here's Tim Harford, author of the weekly column "Dear Economist" in the Financial Times. He's answering a mother's question about how much time her daughter should spend on education vs. looking good for a future rich husband:

Surprising as this may seem in the 21st century, your daughter’s strategy is not unusual. Evidence on speed-dating gathered by the economists Michèle Belot and Marco Francesconi shows that women are attracted by rich men, while men focus more on a woman’s physical appearance. Lena Edlund, another economist, has found that in the areas of her native Sweden where the wealthiest men live, women of prime marriageable age are over-represented.

However, your daughter is only 15; for Edlund, “prime marriageable age” is 25-44. Your daughter is either going to have to get her hooks into this chap unusually early, or she is going to have to keep him on the boil for another decade – a lot of nail-painting.

Not only is she concentrating her investments into a single asset by abandoning her education, but she may even be making her main goal harder to achieve. Belot and Francesconi discovered that a strong social trend towards “assortative mating” means that although educated, high-achieving men are not interested in marrying a rich woman, they do like educated high-achieving women, rather than shallow girls with shiny nails.

Your daughter should learn to work hard and look good at the same time. Not only will it advance her immediate goals, it will also – sadly – stand her in good stead for the rest of her life.

So this girl shouldn't just sit back and hope for missionary dating.
