How will AI transform childhood?
That is the topic of my latest Bloomberg column, here is one excerpt:
In the future, every middle-class kid will grow up with a personalized AI assistant — so long as the parents are OK with that.
As for the children, most of them will be willing if not downright eager. When I was 4 years old, I had an imaginary friend who lived under the refrigerator, called (ironically) Bing Bing. I would talk to him and report his opinions to my parents and sister.
In the near future, such friends will be quite real, albeit automated, and they will talk back to our children as directly as we wish. Having an AI service for your child will be as normal as having a pet, except the AI service will never bite. It will be carried around in something like a tablet, though with a design that is oriented toward the AI.
Recent developments suggest that AI models can be both commoditized and customized more easily and cheaply than expected. So parents will be able to choose what kind of companion they want their kids to have — in contrast to the free-for-all of the internet. The available services likely will include education and tutoring, text or vocalizations of what the family pet might be thinking, dancing cartoon avatars, and much more. Companies will compete to offer products that parents think will be good for their kids. Some of the AIs might even read bedtime stories (in fact, I’ve already heard some of them).
Many parents may be reluctant to let their kids become attached to an AI. But I predict that most families will welcome it. For one, parents will be able to turn off the connection whenever they wish. Simply clicking a button is easier than yanking an iPad out of a kid’s grasp.
Most of all, letting your kid have an AI companion will bring big advantages. Your child will learn to read and write much faster and better, and will do better in school. Or maybe you want your kid to master Spanish or Chinese, but you can’t afford an expensive tutor who comes only twice a week. Do you want your child to learn how to read music? The AI services will be as limited or as expansive as you want them to be.
It is an open question how quickly schools will embrace these new methods of learning. At some point, however, they will become part of the curriculum. Competitive pressures will make parents reluctant to withhold AI from their kids. Even if the AIs are not present in the classroom, some kids will use them to help do their homework, gaining a big advantage, and the practice will likely spread.
Of course children will use these AIs for purposes far beyond what their parents intend. They will become playthings, companions, entertainers and much more. When I was a kid, with no internet and mediocre TV, I created imaginary worlds in the dirt, or with simple household items, and my parents often had no clue. The AI services will become part of this model of spontaneous play, even if parents try to make them purely educational.
What about teenagers? Well, many parents may allow their kids to speak with AI therapists. It might be better than nothing, and perhaps better than many human therapists.
Recommended, and I do discuss some potential risks as well.

Tabarrok on Stranded Technologies Podcast
I talk with entreprenreur Niklas Anzinger on the Stranded Technlogies Podcast. Niklas summarizes some of the discussion:
- This episode is an intellectual journey that discovers insights that can be used by entrepreneurs and city developers. We talk about the Baumol effect that Alex uses to explain the now infamous price chart.
- Alex’s recommendation to new city or governance startups like Prospera, Ciudad Morazan or the Catawba DEZ is to think of city development as a “dance between centralization and decentralization”.
- Economists have developed concepts that are waiting to be commercialized, e.g. prediction markets. In this episode, we talk about dominant assurance contracts and how they could be used in new city developments and fundraising.

My Conversation with Yasheng Huang
Here is the audio, video, and transcript, Yasheng is a China scholar and a professor at MIT. Here is part of the episode summary:
Yasheng joined Tyler to discuss China’s lackluster technological innovation, why declining foreign investment is more of a concern than a declining population, why Chinese literacy stagnated in the 19th century, how he believes the imperial exam system deprived China of a thriving civil society, why Chinese succession has been so stable, why the Six Dynasties is his favorite period in Chinese history, why there were so few female emperors, why Chinese and Chinese Americans have less well becoming top CEOs of American companies than Indians and Indian Americans, where he’d send someone on a two week trip to China, what he learned from János Kornai, and more.
And an excerpt:
COWEN: Now, in your book, you write of what you call Tullock’s curse— Gordon Tullock having been my former colleague — namely, embedded succession conflict in an autocracy. Why has Chinese succession been so stable up to now? And will we see Tullock’s curse whenever Xi steps down, passes on, whatever happens there?
HUANG: I do want to modify the word that you use, stable. There are two ways to use that term. One is to describe the succession process itself. If that’s the situation we’re trying to describe, it is not stable at all. If you look at the entire history of the PRC, there have been so many succession plans that failed, and at a catastrophic level. One potential successor was persecuted to death. Another fled and died in a plane crash. Others were unceremoniously dismissed, and one was put under house arrest for almost 15 years, and he died —
COWEN: But no civil war, right?
HUANG: Yes, that’s right.
COWEN: No civil war.
HUANG: That’s right. There’s another way to talk about stability, which is stability at the system level, and that, you are absolutely right. Despite all these problems with these successions, the system as a whole has remained stable. The CCP is in power. There’s no coup, and there were not even demonstrations on the street associated with the succession failures. So, we do need to distinguish between these two kinds of stability. By one criterion, it was not stable. By the other criterion, it is quite stable.
The reason for that is, I think — although it’s a little bit difficult to generalize because we don’t really have many data points — one reason is the charisma power of individual leaders, Mao and Xiaoping. These were founding fathers of the PRC, of the CCP, and they had the prestige and — using Max Weber’s term — charisma, that they could do whatever they wanted while being able to contain the spillover effects of their mistakes. The big uncertain issue now is whether Xi Jinping has that kind of charisma to contain future spillover effects of succession failure.
This is a remarkable statistic: Since 1976, there have been six leaders of the CCP. Of these six leaders, five of them were managed either by Mao or by Deng Xiaoping. Essentially, the vast majority of the successions were handled by these two giants who had oversized charisma, oversized prestige, and unshakeable political capital.
Now we have one leader who doesn’t really have that. He relies mostly on formal power, and that’s why he has accumulated so many titles, whereas he’s making similar succession errors as the previous two leaders.
Obviously, we don’t know — because he hasn’t chosen a successor — we don’t really know what will happen if he chooses a successor. But my bet is that the ability to contain the spillover effect is going to be less, rather than more, down the road, because Xi Jinping does not match, even in a remote sense, the charisma and the prestige of Mao Zedong and Deng Xiaoping. There’s no match there.
Recommended. And I am happy to recommend Yasheng Huang’s forthcoming book The Rise and Fall of the East.

On graduate student mental health (from my email)
…we often discuss mental health in terms of treatment and selection effects. While more causal inference is needed, I believe it some points are often overlooked.
Personality plays a role: Many in the field can be characterized as overachievers. This behavior can easily turn pathological if it is driven by a fear of failure or a sense that self-worth is contingent on competence. Moreover in a competitive academic environment. Exit may be psychologically very difficult if your self-worth is on the line.
Policies within graduate programs exacerbate the issue: In my program, if a student drops out, the University will not award them a master’s degree if they already have a similar degree from another university. This policy discourages students exit and may keep them in situations that are not beneficial for their mental health.
Economists tend to overrate the effectiveness of educational signals in selecting prospective grad study: Interviews are often not a part of the selection process, which I believe is a missed opportunity to assess a student’s psychological readiness for a PhD program. For many far less stressful jobs psychological testing is standard. In my experience, I only received interviews from programs that had already accepted me (meant to convince me to accept offers).

What should I ask David Bentley Hart?
I will be doing a Conversation with him. David Gordon claims the guy has read more than David Gordon! Here is Wikipedia:
David Bentley Hart (born 1965) is an American writer, philosopher, religious studies scholar, critic, and Orthodox theologian noted for his distinctive, humorous, pyrotechnic and often combative prose style. With academic works published on Christian metaphysics, philosophy of mind, classics, Asian languages, and literature, Hart received the Templeton Fellowship at the University of Notre Dame Institute for Advanced Study in 2015 and organized a conference focused on the philosophy of mind. His translation of the New Testament was published by Yale in 2017 with a 2nd edition in 2023.
A prolific essayist, Hart has written on topics as diverse as art, baseball, literature, religion, philosophy, consciousness, problem of evil, apocatastasis, theosis, fairies, film, and politics. His fiction includes The Devil and Pierre Gernet: Stories (2012) as well as two books from 2021: Roland in Moonlight and Kenogaia (A Gnostic Tale). Hart also maintains a subscription newsletter called Leaves in the Wind that features original essays and conversations with other writers such as Rainn Wilson, China Miéville, Tariq Goddard, and Salley Vickers. Hart’s friendship and substantial intellectual common ground with John Milbank has been noted several times by both thinkers.
So what should I ask him?
What young people say is driving changes in their mental health
I think consistent with Matt's point here — you see young people identifying social media as a source of worsening mental health; but also emphasizing politics and national media.https://t.co/scOXEMNFjJ https://t.co/MGgdNIsz0m pic.twitter.com/hY47EOZFAO

I would stress this point. Most of the explanations for declining teen mental health invoke contagion at one stage of the argument or another. That in turn means the initial causes can be fairly small, relative to the final outcome. Contagion itself is arguably the most important cause.
The Impacts of Same and Opposite Gender Alumni Speakers on Interest in Economics
What is the impact of male and female alumni speaker interventions in introductory microeconomics courses on student interest in economics? Using student-level transcript data, we estimate the effect of speakers on future course-taking in models which use untreated lectures as control groups, including professor and semester fixed effects and student-level covariates. Alumni speakers increase intermediate economics course take-up by 2.1 percentage points (11%). Students are more responsive to same-gender speakers, with male speakers increasing men’s course take-up by 36% and female speakers increasing women’s course take-up by 40%, implying that the effect of alumni speakers is strongly gendered.
That is from a new NBER working paper by Arpita Patnaik, Gwyn C. Pauley, Joanna Venator, and Matthew J. Wiswall.
ChatGPT vs. the experts (Department of Uh-Oh)
ChatGPT’s answers are generally considered to be more helpful than humans’ in more than half of questions, especially for finance and psychology areas.
Most of all, ChatGPT does better in terms of concreteness. Note also that ChatGPT uses more nouns and deploys a more neutral tone than do the human experts. ChatGPT fares worst in the medical domain, but its biggest problem (from the point of view of the human evaluators) is giving too much information and not enough simple instructions. Hmm… In any case, here is the link.
I wonder how well the upgrades are going to do.
Give Cash, Proverb Contest
Give Directly is looking for a proverb to promote the idea of giving directly:
The most common critique of giving cash without conditions is a fear of dependency, which comes in the form of: “Give a man a fish, feed him for a day. Teach a man to fish, feed him for a lifetime.”
We’ve tried to disabuse folks of this paternalistic idea by showing that often people in poverty know how to fish but cannot afford the boat. Or they don’t want to fish; they want to sell cassava. Also, we’re not giving fish; we’re giving money, and years after getting it, people are better able to feed themselves. Oh, and even if you do teach them skills, it’s less effective than giving cash. Phew!
Yet, despite our efforts, the myth remains.
The one thing we haven’t tried: fighting proverb with (better) proverb. That’s where you come in. We’re crowdsourcing ideas that capture the dignity and logic of giving directly.
Submit your direct giving proverb.
The best suggestions are not a slogan, but a saying — simple, concrete, evocative (e.g.). Submit your ideas by next Friday, March 3, and then we’ll post the top 3 ideas on Twitter for people to vote on the winner.
MRU One Million Users!
Marginal Revolution University hit a milestone last week: the one millionth use of our interactive econ practice tools!
Interactive tools help students learn economics and help teachers deliver great econ education. To celebrate, the MRU team has just released a 6-day high school unit plan on inflation complete with lecture slides, videos, and interactive practice and we’re offering high school teachers a chance to win billions of dollars to check it out. (Ok, Zimbabwean billions but still pretty cool!)
More generally, check out our free economics courses and teaching resources at MRU and our superb principles of economics textbook, Modern Principles of Economics. Next stop: Ten million!
Why not get out? Really
Bolotnyy: We found that these moderate to severe symptoms of depression and anxiety were about two to three times more prevalent among PhD students in these eight top-ranked economics PhD programs than in the general population. Suicidality was also about two times what you’d see in the general population.
And:
Economic students are about half as likely as other Harvard PhD students to be in treatment if they have some of these serious symptoms. That’s something that we’ve talked a lot about and tried to understand.
Here is more, brought to you by the AEA. I am very happy to see this work being done, kudos to Valentin Bolotnyy. And I am all for more social connections, better campus mental health counseling, and involved advisors, all of which are listed as potential partial remedies. Yet if I were the AEA, I would be wondering about pushing yet another recommendation — discouraging some people, at the margin of course, from even starting graduate school in economics? And other fields too.
Somehow that option does not receive much consideration. (When I advise people. in part due to this and other data, I am much less likely to recommend graduate school than in earlier times.) Should not part of the mission of the AEA be to think like an economist? What about “exit”? Or is that only for other sectors?
My Conversation with Brad DeLong
Here is the audio and transcript, here is part of the summary:
Tyler and Brad discuss what can really be gleaned from the fragmentary economics statistics of the late 19th century, the remarkable changes that occurred from 1870–1920, the astonishing flourishing of German universities in the 19th century, why investment banking allowed America and Germany to pull ahead of Britain economically, what enabled the Royal Society to become a force for progress, what Keynes got wrong, what Hayek got right, whether the middle-income trap persists, his favorite movie and novel, blogging vs. Substack, the Slouching Towards Utopia director’s cut, and much more.
And here is one excerpt:
COWEN: What do you take to be the best understanding of the 17th-century Scientific Revolution, if indeed you view it as a 17th-century revolution?
DELONG: I always think Joel Mokyr is absolutely magnificent on this. I think he understates the role that having printing by movable type played in creating the community of scientific practice and knowledge seeking.
There’s one thing that happens that is extremely unusual. Back before 1870, there’s no possibility at all that humanity is going to be able to bake the economic pie sufficiently large that everyone can have enough. Which means that, principally, politics and governance are going to be some elite constituting itself and elbowing other elites out of the way, and then finding a way to run a force-and-fraud domination and exploitation scheme on society so that they at least can have enough. When Proudhon wrote in 1840s that property is theft, it was not metaphor. It was really fact.
What does this elite consist of? Well, it’s a bunch of thugs with spears, the people who have convinced the thugs with spears that they’re their bosses, and their tame accountants, bureaucrats, and propagandists. Which means, most of the time, when you have a powerfully-moving-forward set of people thinking about ideas, whether the idea is true is likely to be secondary to whether the idea is useful to helping me keep my place as a tame propagandist in the force-and-fraud domination and exploitation elite machine.
This is a point I’ve stolen from Ernest Gellner, and I think it is very true. Yet, somehow, the Royal Society decides, no. The Royal Society decides nothing except through experiment — what we are going to demand that nature tell us, or tell one of us, or at least someone writes us a letter saying they’ve done the experiment about what is true. That is a miraculous and completely unexpected transformation, and one to which I think we owe a huge amount.
Many interesting points are discussed.
Why are adolescents so unhappy?
Here is a new tack, or rather a very old one:
Using PISA 2018 data from nearly half a million 15-year-olds across 72 middle- and high-income countries, this study investigates the relationship between economic development and adolescent subjective well-being. Findings indicate a negative log-linear relationship between per-capita GDP and adolescent life satisfaction. The negative nexus stands in stark contrast to the otherwise positive relationship found between GDP per capita and adult life satisfaction for the same countries. Results are robust to various model specifications and both macro and micro approaches. Moreover, our analysis suggests that this apparent paradox can largely be attributed to higher learning intensity in advanced countries. Effects are found to be more pronounced for girls than for boys.
That is from a new paper by Robert Rudolf and Dirk Bethmann. Is it the learning per se, or is the learning a proxy for a very particular kind of peer interaction? Via the excellent Kevin Lewis.
