There is some risk to increase birth defects if you do a lot of outdoor gardening when you are pregnant. That can increase rates of toxoplasmosis.

One of the big take-aways from a lot of economic theory is that people should engage in consumption smoothing.

Talking to women about birth can be polarizing.

I think we've moved to thinking of parenting and pregnancy as something in which you should lose yourself.

When I meet people on airplanes and they find out I'm an economist, they usually ask about stock tips.

The basic idea that incentives can be used to motivate behavior is a powerful one. It works for employees, and it has a clear place in parenting, as anyone who has tried to potty-train a recalcitrant toddler with sticker rewards knows.

Because economics is all about optimising, doing the best you can with what you have - it's usually the first place you should look for answers if you want to maximise your happiness.

Education campaigns ... may not be enough, at least not alone. If people have no incentive to avoid AIDS on their own, even if they know everything about the disease, they still may not change their behavior.

Economics works great for planning your life when you don't have a work passion, since we tend to assume that your job delivers only money and you trade off job hours with leisure hours.

But how much you want to invest is going to depend on how much longer you expect to live in the future, even if you don't make those investments.

No one likes doing chores. In happiness surveys, housework is ranked down there with commuting as activities that people enjoy the least. Maybe that's why figuring out who does which chores usually prompts, at best, tense discussion in a household and, at worst, outright fighting.

As people do a task, they improve at it.
