No Tech Workers or No Tech Jobs?

Joy Buchanan1 Comment

Several recent tweets(xeets) about tech talent re-ignited the conversation about native-born STEM workers and American policy. For the Very Online, Christmas 2024 was about the H-1B Elon tweets.

Elon Musk implies that “elite” engineering talent cannot be found among Americans. Do Americans need to import talent?

What would it take to home grow elite engineering talent? Some people interpreted this Vivek tweet to mean that American kids need to be shut away into cram schools.

The reason top tech companies often hire foreign-born & first-generation engineers over “native” Americans isn’t because of an innate American IQ deficit (a lazy & wrong explanation). A key part of it comes down to the c-word: culture. Tough questions demand tough answers & if we’re really serious about fixing the problem, we have to confront the TRUTH:

Our American culture has venerated mediocrity over excellence for way too long (at least since the 90s and likely longer). That doesn’t start in college, it starts YOUNG. A culture that celebrates the prom queen over the math olympiad champ, or the jock over the valedictorian, will not produce the best engineers.

– Vivek tweet on Dec. 26, 2024

My (Joy’s) opinion is that American culture could change on the margin to grow better talent (and specifically tech talent) resulting in a more competitive adult labor force. This need not come at the expense of all leisure. College students should spend 10 more hours a week studying, which would still leave time for socializing. Elementary school kids could spend 7 more hours a week reading and still have time for TV or sports.

I’ve said in several places that younger kids should read complex books before the age of 9 instead of placing a heavy focus on STEM skills. Narratives like The Hobbit are perfect for this. Short fables are great for younger kids.  

The flip side of this, which creates the puzzle, is: Why does it feel difficult to get a job in tech? Why do we see headlines like “Laid-off techies face ‘sense of impending doom’ with job cuts at highest since dot-com crash” (2024)

Which is it? Is there a glut of engineering talent in America? Are young men who trained for tech frustrated that employers bring in foreign talent to undercut wages? Is there no talent here? Are H-1B’s a national security necessity to make up the deficit of quantity?

Previously, I wrote an experimental paper called “Willingness to be Paid: Who Trains for Tech Jobs?” to explore what might push college students toward computer programming. To the extent I found evidence that preferences matter, culture could indeed have some impact on the seemingly more impersonal forces of supply and demand.

For a more updated perspective, I asked two friends with domain-specific knowledge in American tech hiring for comments. I appreciate their rapid responses. My slowness, not theirs, explains this post coming out weeks after the discourse has moved on. Note that there are differences between the “engineers” whom Elon has in mind in the tweet below versus the broader software engineering world.

A Wartime Natural Experiment About Copyright

Joy Buchanan2 Comments

One of the hardest questions in copyright policy is: “What would have happened otherwise?” When Disney lobbies for longer copyright terms or academic publishers defend high subscription fees, we struggle to evaluate their claims because we can’t observe the counterfactual. What would happen to creativity and innovation if we shortened copyright terms or lowered prices?

This is what makes Biasi and Moser’s 2021 study in the American Economic Journal: Microeconomics valuable. They examine a rare “natural experiment” from World War II – the Book Republication Program (BRP) – which provides insights into how copyright affects the spread and use of knowledge.

In 1942, the U.S. government allowed American publishers to reprint German scientific books without seeking permission from German copyright holders (though royalties were still paid to the U.S. government). This created a test case: German books suddenly became cheaper, while similar Swiss scientific books (Switzerland being neutral in the war) maintained their original copyright protection and prices.

This setup lets us answer the counterfactual question. What happens when you maintain basic royalty payments but prevent monopoly pricing? The researchers compared the same book before and after the policy change, German books versus Swiss books, areas near libraries with these books versus those without, and usage by English-speaking scientists versus others. Such comprehensive comparison groups are rarely available in copyright research.

The authors report that when book prices fell by 10%, new research citing these books increased by 40%. The benefits spread beyond elite institutions, with new research clusters emerging wherever scientists gained access to these books. This does not appear to just be shifting citations from one source to another – there was genuine new knowledge creation, evidenced by increased patents and PhD production.

Such clean natural experiments in copyright policy are rare (there are a few laboratory experiments). Most changes come from lobbying (like the “Mickey Mouse Protection Act”) or technological disruption (like music streaming), making it hard to isolate the effects of copyright itself. The BRP provides uniquely clear evidence that moderate copyright protection – rather than maximum protection – might better serve innovation.

As we debate copyright terms and academic paywalls today, this historical accident of war gives us something valuable: empirical evidence about what happens when you find a middle ground between total copyright protection and unrestricted access.

David Hume’s Wisdom in the Age of AI

Joy Buchanan1 Comment

Nothing says “Christmas cheer” like David Hume and empiricism. I am at EconLog this week with

Rediscovering David Hume’s Wisdom in the Age of AI

In our era of increasingly sophisticated artificial intelligence, what can an 18th-century Scottish philosopher teach us about its fundamental limitations? David Hume‘s analysis of how we acquire knowledge through experience, rather than through pure reason, offers an interesting parallel to how modern AI systems learn from data rather than explicit rules.

In his groundbreaking work A Treatise of Human Nature, Hume asserted that “All knowledge degenerates into probability.” …

Furthermore, I explain why this could have implications for the limits of AGI, if LLMs learn from experience and are limited in the number of datapoints they can observe. It is also a follow-up to my summer post: Is the Universe Legible to Intelligence?

Updated List of Top Posts for 2024

Joy Buchanan1 Comment

In August, I listed the Top EWED Posts of 2024. Here are a few more highlights. This list is roughly based on web traffic, starting with the highest number of views for 2024, since the August list.  

  1. Mike Makowsky has the top post since August with Bad service is a sign of a better world. “What if service in restaurants, hospitality, etc is, in fact, lower in quality than it was one or two decades ago? I would like to suggest that this is a good sign of improving times.”  Thoughtful. Recommended. Bosses will not be requiring “15 pieces of flair” anymore. I have noticed that restaurant servers these days seem to wear whatever they want. It was previously noted by Mike that Kitchen staff were canaries in the coal mine.

2. Grocery Inflation Since 2019: BLS Data is Probably About Right by Jeremy-“What if we actually looked at receipts?”-Horpedahl. You can find him on Twitter/X.

3. You know it’s good when a post with such a cryptic title goes viral. Mike wrote about the topic people were thinking about, in the moment: At the moment (updated 10/22/24) Sometimes we write about the economics community and what began as a critical mass of people that used to call itself #EconTwitter. Some of those people have moved to Bluesky. You can find Mike there at @mikemakowsky.bsky.social, and most of us have accounts there. Getting social media just right is tricky. If you follow the right people and don’t waste too much time on it, then social media can be part of How to Keep Up With Economics (James).

4. Predicting College Closures: Now with Machine Learning James Bailey brings the important (unwanted) news that not all college are going to make it through the next decade, and there are signs. This follows up on what was previously listed as a top post in August: Predicting College Closures

5. Publish or Perish: A Hilarious Card Game Based on Academia My review of a new board game. If it’s not for you, it’s not for you. I played a test copy with some fellow nerds and had a great time.

6. Jeremy explains, “… fast food prices (“limited service meals”), which have definitely outpaced wages over the past 4 years, and continue to grow…” Grocery Inflation is Under Control, Fast Food Prices Aren’t

7. Jeremy asks, Did 818,000 jobs vanish?

8. Scott’s saga is perhaps attracting traffic from search engines from people with the same problem. Recovering My Frozen Assets at BlockFi 2. Scams and More Scams

9. Post-Pandemic Lumber Market Zachary Bartsch writes, “People used to talk about higher gasoline prices all the time, but never discussed with the same enthusiasm when prices fell. The same is true for lumber.” Good for teaching about supply and demand.

10. I Give Up, Standard & Poor’s Wins James lets us learn from his journey- “my stock picks underperformed the incredible 26% return the S&P has posted so far this year.”  This is something most people would rather not admit, and yet for most of us it’s true.

11. James explains, “Cheapflation”: Inflation Really Does Hit the Bottom Harder. People were mad about inflation. Voters were mad about inflation. It’s worth understanding better. Some of us are in an echo chamber and need to peer out, especially if we think a lot about how (in fact) the world is getting better. Or maybe we even think about data indicating that On Average, American Wage Earners are Better Off Than They Were Four Years Ago (Jeremy).

12. Why Podcasts Succeeded in Gaining Influence Where MOOCs Failed attracted some attention. If you are being honest, would you have predicted a priori that Joe Rogan talking in a closed room FOR HOURS would outdo Ivy League professor lectures? In retrospect, it might seem obvious, but I probably would have gotten the prediction wrong. MOOCs and podcasts both launched around the same time because the internet lowered the cost of broadcasting. They both had some success. In terms of shaping culture or voting behavior, I think it’s clear that podcasts win. Until a product is launched on the market, we just don’t know what will become popular, which is a topic that came up in the podcast I recorded recently: Joy on The Inductive Economy podcast

Speaking of what I don’t predict, EWED is starting to get web traffic from LLMs like chatgpt.com. Right now, it’s very small compared to Google search. For a while, I wondered if LLMs would simply plagiarize us without giving us any credit. Maybe that’s our raison d’être. Here’s me being dramatic about it in 2022  –  “Because of when I was born, I believe that something I have published will make it into the training data for these models. Will that turn out to be more significant than any human readers we can attract?” 

However, writers of the world, LLMs might start giving you credit. There is some demand from users for sources and citations. (My paper on made up sources). 

A little more credit to the true 2024 EWED all-stars, even though they were already listed in August: Young People Have a Lot More Wealth Than We Thought, by Jeremy Horpedahl,  continues to be a top performer. And, Mike wrote about an important current event in culture: Civil War as radical literalism   

While we are settling scores and doing web traffic round-ups, there is one thing I’d like to put on the record. I made one resolution last year, publicly on January 3, 2024. I have made good on this promise. The people who run the AdamSmithWorks website have informed me that I wrote their top post of the year, Would Adam Smith Tell Taylor Swift to Attend the Super Bowl?

Humans are struggling to understand LLM Progress

Joy Buchanan1 Comment

Ajeya Cotra writes the following in “Language models surprised us” (recommended, with more details on benchmarks)

In 2021, most people were systematically and severely underestimating progress in language models. After a big leap forward in 2022, it looks like ML experts improved in their predictions of benchmarks like MMLU and MATH — but many still failed to anticipate the qualitative milestones achieved by ChatGPT and then GPT-4, especially in reasoning and programming.

Joy’s thoughts: A possible reason for underestimating the rate of progress is not just a misunderstanding of the technology but a missed estimate on how much money would get poured in. When Americans want to buy progress, they can (see also SpaceX).

I compare this to the Manhattan project. People said it couldn’t be done, not because it was physically impossible but because it would be too expensive.

After a briefing regarding the Manhattan Project, Nobel Laureate Niels Bohr said to physicist Edward Teller, “I told you it couldn’t be done without turning the whole country into a factory.” (https://www.energy.gov/lm/articles/ohio-and-manhattan-project)

We are doing it again. We are turning the country into a factory for AI. Without all that investment, the progress wouldn’t be so fast.

Handmade Sweaters Cost $500

Joy BuchananLeave a comment

If you spend any time on Twitter/X, you must know the suit guy, Derek. Given my interest in the economics of fast fashion, I read his new thread about expensive craft sweaters.

He explains that some clothes on this earth are still made by hand. Artisan sweaters cost a lot because of the labor. Supporting that art or tradition is fine, if you have $500 on hand.

The comments on the thread are interesting as well. (Caveat, a good number of anonymous accounts are trolls bent on your destruction – read accordingly always.)

One comment, presumably by an amateur knitter in a rich country: “As a knitter, I know how much work would go into hand making sweaters like these. That’s not even taking into account the cost of a good wool yarn. If anything, they are underpriced.”

Not a lot of people want to spend $500 on a sweater. I really loved this reply about thrift stores. We don’t all have to buy the sweater new.

Someone who has been thinking about how goods change hands in the modern economy is Mike Munger who wrote Tomorrow 3.0: Transaction Costs and the Sharing Economy.

My related posts on fast fashion (a.k.a. factory-made sweaters cost $5):

Cato Globalization book out in paperback – my most optimistic take on this is that AI will facilitate the sharing part of the sharing economy, which will help justify the cost of high-quality new garments.

Is the repair revolution coming? – in my opinion, probably not, although I still think AI could help with this

Weight Lifting is for You

Joy Buchanan1 Comment

This is a guest post by Mary Buchanan, a Board Certified Behavior Analyst. Here she explores the intersection of behavioral economics with her own health and fitness behavior change.

My childhood dentist often said, “Take care of your teeth, or they’ll go away.” As I approach my 40th birthday, I’m learning the same is true of my muscle mass. I can use it or lose it. And I can lose it faster or slower based on my lifestyle choices. 

As a behavior analyst, I have spent many years practicing the science of behavior, specifically teaching others how to master new, meaningful skills. I see myself as my own client now as I work to replace my old aimless approach to fitness with evidence-based eating and exercise interventions. 

I wish I could say I embraced strength training as soon as I heard about its benefits. Instead, as I noticed more and more recommendations for women to “lift heavy”, I kept filing that information away for someday in the future. When I joined a gym last January, I returned to what I used to do in years past: Pilates classes or cardio machines. After 9 months of that approach with no benefits to show for my efforts, it was time to change my behavior.

Behavioral economics has a term for what causes people to resist changing their behaviors without a significant incentive for doing so: status quo bias. 

Another behavioral economics term, loss aversion, helps to explain what moved me into action. Loss aversion refers to how people are often more motivated not to lose something they have than they are motivated to gain something similar. All humans start to lose muscle mass around age 30, but that fact was not on my radar until recently. I wasn’t interested in building muscles when I thought mine were adequate to my daily tasks. Now that I realize my muscle loss has been underway for years and the liabilities of that loss are clear to me, I’m motivated to rebuild and mitigate future muscle loss. How? By doing heavy lifting 2-3x per week and eating enough protein for my body to keep the muscle it makes. 

There are many great resources that provide advice in this area, but I’ve decided to begin
with learning from Dr. Stacy Sims since she specializes in what works for women. Based on what I’ve learned, here are my target behaviors for increase:

  • Practice strength training for at least 30 minutes, 2x per week.
    Dr. Sims says 3x per week is better, but 2x is an acceptable minimum that I can commit to either through classes at a gym or YouTube videos. As a behavior analyst, I know that I’m more likely to maintain a new behavior pattern when it is easy to feel successful early and often.
  • Continue to challenge myself throughout strength training by adding weight as I get stronger.
    To stimulate muscle growth you must challenge your muscles so they break down and repair stronger. How heavy is enough? If you lift a weight 10x and it’s difficult to lift on the last two reps, but still possible for you to maintain good form, that is an appropriate weight for you to train with. When that weight gets easy to lift, it’s no longer heavy enough for your training purposes.
  • Increase my healthy protein intake.
    In Roar, Dr. Sims suggests that women aim for .75-0.8 grams of protein per lb. on a light or non-training day, and increase to 1-1.2 grams of protein per lb. on strength training days. 

Working on these goals together creates synergy. I am more motivated to make healthier eating choices because my eating is connected to my strength training goal. Strength training has also become more exciting for me the more I’ve learned about its benefits, including:

  • Increased metabolic rate
  • Improved posture and stability
  • Stronger bones
  • Better blood pressure control
  • Improved immunity
  • Maintenance of healthy body composition (lifting heavy helps maintain lean muscle and reduce fat gain)

As if that weren’t enough, I have another reason to keep going. As soon as I started resistance training, my sleep improved! I’ve had difficulty sleeping for many years already, both with falling asleep and staying asleep, and honestly, if sleeping through the night was the only benefit available to me from resistance-based workouts, I would still be all in.

While none of this constitutes professional medical advice, it is worth looking into, especially if you, like me, never saw role models strength training as a young person. Once you understand how it works in your favor now and as you age, the benefits are too good to pass up.

Joy on AI in Higher Education

Joy Buchanan1 Comment

I was interviewed for an article “Navigating AI in Christian Higher Education“. Here’s an excerpt:

Rosenberg: What impact do you foresee in your field due to the increasing sophistication of AI, and what kind of skills do you think your students will need to be successful?

Buchanan: AI will reshape economic analysis and modeling, making complex data processing and predictive analytics more accessible. This will lead to more sophisticated economic forecasting and policy design. Economists will become more productive, and expectations will rise accordingly. While some fields might resist change, economics will be at the forefront of AI integration.

For students aiming to succeed, it’s crucial to embrace AI tools without relying on them excessively during college. Strong fundamentals in economic theory and critical thinking remain essential, coupled with data science and programming skills.

Interdisciplinary knowledge, especially in tech and social sciences, will be valuable. Adaptability and lifelong learning are key in this evolving field. Human skills like creativity, communication, and ethical reasoning will remain crucial.

While AI will alter economics, it will also present opportunities for those who can adapt and effectively combine economic thinking with technological proficiency.

Cato Globalization book out in paperback

Joy Buchanan1 Comment

A new book is out with chapters by me, Deirdre McCloskey, and others.

Book Title: Defending Globalization: Facts and Myths about the Global Economy and Its Fundamental Humanity

The COVID-19 pandemic, war in Ukraine, simmering US-China tensions, and rising global populism have led to globalization facing renewed attention-and criticism-from politicians and pundits across the political spectrum. Like any market phenomenon, the free movement of people, things, money, and ideas across natural or political borders is imperfect and often disruptive. But it has also produced undeniable benefits-for the United States and the world-that no other system can match. And it’s been going on since the dawn of recorded history.

The original essays compiled in this volume offer a diverse range of perspectives on globalization-what it is, what it has produced, what its alternatives are, and what people think about it-and offer a strong, proactive case for more global integration in the years ahead. Covering the basic economic and political ideas and historical facts underlying globalization, rebutting the most common arguments against globalization today, and educating readers on the intersection of globalization and our societies and cultures-from where we live to what clothes we wear and what foods we eat-Defending Globalization demonstrates the essential humanity of international trade and migration, and why the United States and the rest of the world need more of it.

You can read a summary, in a previous EWED blog post, of my chapter on fashion, previously posted on the Cato website as Fast Fashion, Global Trade, and Sustainable Abundance.

It takes all of us to be rich. We need “a great multitude that no one could count, from every nation, tribe, people and language,” so to speak.

Two years ago, on Twitter, I summarized my contribution as follows, in the form of a dialogue:

Person from the Past: “So, how is it with 8 billion people?”

Me Today: “It’s bad. We have too many clothes.”

Person from the Past: “Right. With 8 billion you wouldn’t have enough clothes for everyone.”

Me Today: “Too many.”

I made it to the book launch event in D.C. near the Capitol.

Some people still have not heard of “fast fashion.” Maybe you heard it here first: New legislation is likely coming to regulate the clothing industry. It might start at the state level, in progressive places like California or Seattle. Demands include making information about supply chains more transparent and taxing the clothing companies in order to pay for trash disposal. For example, you can read about the New York Fashion Act. Similar to the way the food companies have to provide clear information about calories, clothing retailers might have to provide more information about chemicals, labor, and disposal issues.

Plastic fibers making new clothing cheap. I sometimes hate the flood of cheap products that American families are drowning in. Plastic products are so cheap to stamp out and give to kids. Some days you’ll find me grumpy about the latest bag of plastic swag and candy my kids came home with. There are some negative externalities to consuming tons of plastic items and tossing them out.

It’s a privilege to have this problem. Perhaps we are overindulging in clothing abundance and need some modern solutions to modern problems. We also need to figure out how to stop getting obese off of food abundance. (Hello, Ozempic.) But let’s still be grateful for the abundance, on this Thanksgiving week. My controversial take is that it’s good for the cost of clothing to be low. We don’t want to regress. We don’t want to make clothing scarce again.

If you were to want to cite my work on fashion and globalization, then you could use something like this:

Buchanan, Joy. “Fast Fashion, Global Trade, and Sustainable Abundance” (2024) In S. Lincicome, & C. Packard (Eds.), Defending Globalization: Facts and Myths about the Global Economy and Its Fundamental Humanity, Cato Institute, (pp. 367 – 380).

Human Pettiness Knows No Bounds

Joy Buchanan1 Comment

Just when you think there might be one arena of human life free of status competition, you will turn out to be wrong.

Consider the 4th graders who get to do “safety patrol” as volunteer work. This is a badge of honor and the kids like power. A casual observer might think that any kid who volunteers to do safety patrol would simply be having a great experience. Surely this is as simple as adding a unit of utility from consumption, in comparison to the times when the child is not allowed to do safety patrol.

But all is not well. Jackson Carter, says Rachel Pratt, has been hogging the prime safety patrol spot for weeks. He walks to school earlier than anyone and sits on the good spot, excluding the other 4th graders from having the chance to catch the highest volume of younger kids to boss around.

Rachel Pratt and several other girls are conspiring to, collectively, prevent Jackson from getting so disproportionately many days on the prime spot. They have agreed that if any one of them can beat him to the spot, they will share it with anyone except Jackson. The crew has also planned to loudly comment on the situation in earshot of the school principal in hopes that Jackson will have to share the spoils more evenly.

Do humans even want to be happy?
