I’ve recently added a new member to my family and become a first time parent! Here are some scattered thoughts and observations I’ve had about the experience. Beware all are basically projections of my existing biases as seen through a new experience.
Policy does not seem to take into account externalities of children. This is really the umbrella observation guiding many of these points. In a market economy, you pay for someone else’s time via wages. If there’s a new industry that forms from the advance of technology (say software engineer or YouTube creator), you can convince people to provide that labor in the new industry by paying them, and other industries will need to adjust to deal with more demand on the labor pool. They must either reduce output, offer better wages, or advance the productivity of their remaining workers. In this way, the labor pool for a given industry can expand or shrink based on the market forces of that industry, with some lag for education requirements.
However, you can’t change the whole pot of labor with market forces except in specific circumstances. Immigration is one of those, but we’ll set that aside for now. Let’s focus on population growth through new babies. Of course, adding a worker to the economy doesn’t just add to the supply side; new workers also buy things! You may think these cancel out, but I’m doubtful. As Adam Smith observed, the division of labor increases productivity and the more people you have, the larger economy you have and the larger the degree of division of labor and extent of the market, leading to super-linear productivity gains.
But just because some jobs’ wages go up doesn’t mean there are more babies being born; there’s no market feedback mechanism for this! You pay the worker once they are old enough to work; you don’t pay their parents to raise them! This results in a missing positive externality. The invisible hand is willing to pay for more workers to work in America’s massively productive economic engine (which we can see through huge immigration pressures). But there’s no market mechanism to pay parents to provide more workers! Thus the expensive costs are born by the family raising kids and the benefits accrue to the economy broadly, a classic positive externality problem.
Matthew Yglesias adds a related argument in One Billion Americans that is specific to the U.S.; there are positive spillover effects from having a large market in the U.S. which is fueled by an integrated largely free market encompassing hundreds of millions of productive workers. The U.S. economy, because of its size, dominates global commerce as companies seek to sell in the American market, which in turn exports U.S. cultural products and values of liberalism.
However, despite these economic and nationalistic benefits, failing fertility rates and deadlocks on immigration mean U.S. policy hasn’t really prioritized population growth. Assuming they should, it’s interesting to see from a parental perspective how U.S. policy impacts the decision to have children. Largely, it seems they work in the wrong direction.
The Baumol Effect is real. The Baumol Effect or Baumol’s Cost Disease is the rise of wages in jobs that have not seen increased labor productivity simply because of the rising salaries in other jobs. For most of the economy, jobs continually become massively more productive through the huge engine of a free market economy investing in new technology and capital. You expect to see rising wages for jobs in that industry since the workers are now more productive even as the overall cost of goods produced can continue to fall. For example, agriculture used to take up the vast majority of labor in the economy but is now a very small part, yet food is more plentiful than ever because mechanization and logistics is so advanced.
But some jobs have seen little labor productivity improvement, notably childcare; we don’t have robots or software that can take care of babies. So that labor needs to be done by parents or hired out via nannies or daycare. But today nannies, daycare workers, and especially parents have many more productive things to do in the economy because of the advanced capabilities and technology of the market. So the opportunity cost of taking care of children is massive. Being a new parent, you feel this viscerally. One week you are at a high paying intense job automating workloads and trying to streamline business processes that handle billions of dollars a year, and the next week you can’t get any sleep because you have to change diapers.
To be clear, I’m not complaining! Parental leave is actually a nice break despite the lack of sleep. But the cost to e.g. my employer and the economy broadly is almost hilarious. And yet, clearly there’s an incentive mismatch since collectively, the economy benefits if there are more children born in the long-run due to children’s eventual contributions to the economy and to innovation.
One could imagine a policy to try and encourage people to have children at a younger age when the opportunity cost to the economy is lower (since less experienced workers are probably less productive). But of course, the most likely to take advantage of this policy are probably people whose opportunity costs are lower anyway (the least productive workers), which means the benefits are skewed towards the members of the economy least needing this. Moreover, targeting any government policy directly at high earners is going to be an impossible political ask anyway.
Build more homes. One of the first things we realized is that we needed more space. However, our current job situation means we aren’t likely to stay in our current city for very long and so we had opted against buying a house when we had the option a few times given closing costs. There’s also some benefit I find from renting from a corporate run apartment complex with an always on-call maintenance staff. I’m sure at some point I’ll be more interested in DIY type repairs but not right now.
However, there’s not many options for people with children or especially multiple children who would like to live in an apartment. And my city is more affordable than most. This is of course just a small reflection of the overall housing overregulation we are imposing on the entire English-speaking world. The U.S. is actually more affordable than Canada, the U.K., or New Zealand in many cases, yet the U.S. could be so much better. The most frustrating part of this is that it would cost local governments literally nothing to allow more housing to be built. In fact, governments would likely see revenues rise as land value would be improved. Private actors are completely willing to provide desperately needed supply all up and down the market, but local governments have been coopted by literally landed interest groups to keep a lid on housing supply to monopolize already built housing.
It’s evil, it’s expensive, it saps growth, extracts rents for people who are not contributing to the economy, it violates property rights, and also as a smaller side-effect, it makes it harder to have a family! These are awful policy impacts and we should choose to do better.
Preeclampsia is pretty common. Preeclampsia is a condition that can occur during pregnancy characterized by high blood pressure and signs of damage to other organ systems, most often the liver and kidneys. It usually begins after 20 weeks of gestation. The exact cause is not known, but it is thought to be related to problems with the placenta, and it occurs between 5-8% of pregnancies.
I had the misfortune of having to see this firsthand and it was quite scary. Ultimately it led significant symptoms requiring an earlier than expected induced delivery and my child having to be in the NICU for over a week. Everyone is doing well now, but this seems like a major policy problem if we take as given that there are massive spillover effects to having more children. No one would get on a plane if there was a 5% chance of a serious complication requiring experts to be consulted just to land the plane. I’m not an expert on NIH funding categories, but it doesn’t appear that preeclampsia is a major priority. If long term economic growth matters and thus spillover effects from population growth matter, should this cause area be higher?
Artificial wombs would be amazing. The follow up to the last point: there are promising technologies that would solve the problem of preeclampsia and many others. Pregnancy sucks. It’s physically taxing, it can make women feel miserable for months, and there are serious risks of complications. If we can replace natural gestation with artificial wombs, we can likely reduce risks to both baby and mother and just make having children less stressful. It also means there’s less drag on the economy because women don’t have to trade off being in physical discomfort at work for several months or taking that time off.
A year ago ago when a tweet went viral talking about artificial wombs, there was a strange pushback I saw from people claiming it wasn’t “natural”. I investigated some of these claims the best I could on Twitter, but the argument really made about as much sense as you’d expect. “Natural” to me means dying from smallpox and dysentery. There’s nothing good or beautiful about dying in the state of nature. Preventing horrific and common complications for women giving birth in the 21st century is a no-brainer.
Emily Oster is really helpful. Emily Oster is an economist and author who publishes on parenting. Her books are written for non-academics and summarize the current findings for childcare and pregnancy. Her work makes it really clear what the data indicates on what’s important or not. She’s controversial because her interpretation of the data on drinking during pregnancy is that a drink or two a week during pregnancy does not have much negative effect. This is against the recommendation of most doctors in the U.S.
I haven’t actually heard any doctors cite specific studies to refute Oster’s position, but honestly, I’m of the position that alcohol is probably just bad for you regardless even if in moderate amounts the negative effects are small. I often go weeks without drinking anyway, so cutting down some more isn’t particularly difficult. So feel free to be more cautious than Oster on this point, but I don’t think it negates the overall benefits of her work.
Each chapter contains a nice summary of the key points, so if a couple weeks later you can’t remember the takeaways, its easy to look them up quickly and trigger the rest of your memory of the chapters. The only real concern is that her books are somewhat short and so I’ve found it important to have other child-rearing and pregnancy books available for more specific questions. However, Oster also has a LLM trained on her books and newsletter where you can ask specific parenting questions and it will find the citations related to your question and summarize an answer.
