Many women don’t feel recognized for all the work they do at home. When their husbands come home late from the office to something other than total bedlam, the oblivious men often fail to provide any appreciation or recognition. Would it help if women got paid for their housework? And if so, what is the best way to set up those payments?

—Lisa

I can’t think of any context in which one partner in a family should directly pay the other. But we do need to make sure that earning inequality doesn’t turn into power inequality.

One of the best (and worst) things about money is that it is easy to measure. So each partner’s financial contributions to the household are very clear, and differences can be overemphasized.

Consider a couple in which Person A earns much more than Person B, but Person B does everything else for the household. In such a case, A’s contribution to the relationship is easily quantified (bringing home most of the bacon), whereas B’s bit (taking care of the house, raising the children, dealing with paperwork, bills and so on) can’t be measured as precisely.

If the couple focuses on what’s easy to measure, A’s contribution looks more central. So A could feel more deserving, entitled and commanding while contributing less overall.

There is no magical solution to this problem, but one good step is to deal directly with the flow of money. Start by having one joint checking account for all income and ongoing expenses. On top of that, open two separate savings accounts (one for each partner), and split all savings equally into them.

Legally speaking, this type of accounting doesn’t make any difference, but in psychological terms, it makes a key statement about equality in financial contributions. It could weaken the link between financial contribution and power and offer a more holistic view of contributions to family life.

What can businesses learn from your academic field of behavioral economics?

—Bella

As with any other scientific endeavor, my field has reached, over time, a better understanding of its domain—human behavior. The process has been slow, but the lessons are accumulating.

We have found, for example, the principle of loss aversion: It turns out that we humans hate losing more than we enjoy gaining. Or the IKEA effect—the finding that, once we take part in making something (like IKEA furniture), we start really liking it, and we assume that other people will like our creation too. These are discoveries that businesses can use in developing their products and services.

For all that we’ve learned, however, I suspect that the most important lesson is how little we know—the lesson of humility. We understand a great deal about human behavior, but we also have a lot of gaps, assumptions and blind spots. By training, social scientists are happy to admit how little we really know and much room there is for improvement.

If businesses adopted this approach, trusting their intuitions less and relying on research more, they would get a very high return on investment. Admitting our shortcomings is an important first step.

We host a lot of overnight guests. Should I change the sheets on the guest bed every time a new guest arrives, even if the last one only stayed with us for one night? —Debbie

I am sure that you don’t want to tell your new guests that they are using “only slightly used linens,” and I am almost sure that you don’t want to hide things from your guests—so yes, change the sheets every time.
