A critical problem is one that people are willing to pay a considerable price to have solved

Wednesday, December 10th, 2025

Politics is nothing but an ocean of hyperbole, Bryan Caplan reminds us, as he cites this passage from Edward Banfield‘s 1974 classic, The Unheavenly City Revisited:

A great part of the wealth of our country is in the cities. When a mayor says that his city is on the verge of bankruptcy, he means that when the time comes to run for reelection he wants to be able to claim credit for straightening out a mess that was left to him by his predecessor. What he means when he says that his city must have state or federal aid to finance some improvements is (1) the taxpayers of the city (or some important group of them) would rather go without the improvements than pay for it themselves); or (2) although they would pay for it themselves if they had to, they would much prefer to have some other taxpayers pay for it. Rarely if ever does a mayor who makes such a statement mean (1) that for the city to pay for the improvement would necessarily force some taxpayers into poverty; or (2) that the city could not raise the money even if it were willing to force some of its taxpayers into poverty. In short, the “revenue crisis” mainly reflects the fact that people hate to pay taxes and that they think that by crying poverty they can shift some of the bill to someone else.

[…]

That we have not yet been willing to pay the price of solving, or alleviating such “problems” even when the price is a very small one suggests that they are not really critical. Indeed, one might say that, by definition, a critical problem is one that people are willing to pay a considerable price to have solved.

It was difficult to arrive at a proper price

Sunday, December 7th, 2025

Now It Can Be Told by Leslie M. GrovesIt was difficult to arrive at a proper price, General Groves explains (in Now It Can Be Told: The Story of the Manhattan Project), for uranium ore:

By this time it was certain that the material was of immense value to the United States, provided the bomb worked. To the seller it was of great potential value if atomic energy should prove to have either military or peacetime value. Otherwise, it was worth only the value of its radium content. And if our reactor theories were sound, the radium would lose most of its value since radioactive cobalt could largely replace it.

It did have one definite value and that was what it cost to produce. Yet even this was difficult to establish fairly, for the unit production cost was much less at Shinkolobwe than in Canada or on the Colorado Plateau. Its value had never been determined in the open market and now there was only one purchaser and one seller.

As a Belgian, Sengier appreciated fully the absolute necessity of an Allied victory. It was his broad, statesman-like attitude that made it possible for us to reach an agreement satisfactory to all.

It was a distinct pleasure for me after the war to recommend the award of the Medal of Merit, the highest civilian award made by our government, to Edgar Sengier for his great services to the United States, to Belgium and the free world in making available to us adequate supplies of Belgian Congo uranium. It was also my pleasure to present this award at a ceremony in my office in Washington. Security restrictions had not yet been lifted on this phase of the MED operations and the ceremony was private and unpublicized. It has always been a source of regret to me that Sengier’s services, and particularly his foresight, could not receive full public recognition at the time.

A cruise ship the size of a country

Saturday, December 6th, 2025

On his way to India last year, Bryan Caplan connected through Abu Dhabi, the capital of the United Arab Emirates (UAE) and toured its sister-city, Dubai, too. He shares his reflections on the United Arab Emirates:

In cleanliness and crime, UAE rivals Japan.

[…]

The key ingredient of Emirati success: 88% of UAE’s population is foreign-born. That’s the highest share of any country on Earth.

[…]

I chatted with workers from both Zimbabwe and Sierra Leone. Yes, would-be migrant workers face a government approval process, so the border is not 100% open. But if you want to work hard to make a better life for yourself, your prospects of landing a work visa are decent no matter how humble your credentials.

Abu Dhabi and Dubai are living proof that Michael Clemens’ “Trillion Dollar Bills on the Sidewalk” is literal truth. Both cities look like Coruscant from Star Wars. They are absolute marvels: Gleaming cities of the future where humanity gathers to produce massive wealth. And without mass immigration, almost none of this could have been built!

[…]

In a country where everyone is rich, rich people would have to hire other rich people to clean their homes, cook their food, and watch their kids. In a nativist UAE, the only way to get good value for your money would be to leave the country!

[…]

A typical demagogue would have objected, “We don’t want to become a minority in our own homeland,” but Zayed boldly forged ahead — and created a cruise ship the size of a country. Since 1971, UAE’s population has grown from 280K people to 9.5 million. A miraculous multiple of 34x.

[…]

Most observers glowingly describe UAE’s overflowing welfare state. In a sense, they’re right.

[…]

In a more important sense, however, the UAE’s welfare state is admirably austere, because these lavish benefits are limited to Emirati citizens — and these citizens are a tiny minority of the population. If 88% of the residents of Sweden were ineligible for redistribution, no one would call it “a generous welfare state” — no matter how high the benefits for the remaining 12% happened to be.

[…]

Instead, the UAE has decisively Westernized two initially un-Western populations: native Arab Muslims and Third World migrants. How? By creating an economy dominated by Westernized multinationals. Though the Western population is low, their “soft power” has slowly but surely taken over the soul of the UAE. Verily, Western culture is a hardy weed.

[…]

“What about businesses withholding their workers’ passports?” That’s now illegal, and locals tell me the new law is well-enforced. But either way, it’s a rounding error. Foreign workers have phones, so what do you think they tell their friends and family back home? “Don’t come; they’ll confiscate your passport”? Or, “Definitely come; in five years you’ll return a rich man”?

Ponder this: If a foreigner causes problems in the UAE, the standard punishment is deportation. So how dire could the problem of withholding passports have ever been? The main function of the new UAE law is not to protect foreign workers from employers but to protect the UAE’s reputation from international muckrackers.

It’s living proof that “trillion dollar bills on the sidewalk” is not silly blackboard economics

Thursday, December 4th, 2025

Bryan Caplan argues that the so-called “cultural costs” of immigration would have to be astronomical to outweigh the tens of trillions of dollars of gains we’re forfeiting every year from restricting it:

And they’re clearly not. If natives really cared so much about their cultures, they would be migrating en masse to low-immigration areas of their countries. They aren’t.

[…]

Since they almost never do, we should infer that their cultural attachment is weak.

This first comment, from Torches Together, offers a British perspective:

The first point seems incredibly poorly thought through.

People very clearly do move away from high-immigration neighbourhoods! This is well documented in the UK and France at the population level.

White Britons tend to move to majority-white (95%+) areas in their 30s when having kids.

We also see macro-level shifts in the classic “white flight” cases: Bradford, Saint-Denis, Southall, Blackburn, Tower Hamlets. Entire neighbourhoods that were 99% White in the 1950s are now over 90% minority.

And the answer to the question “Why don’t people move across the country?” is already in the preceding paragraph. “Somewheres” are defined by attachment to place, not race or nation or ethnicity. If you’re from south London and you’re uneasy about the pace or nature of demographic change, your options typically look like:

1) Stay put – keep your attachment to place, with less attachment to the area’s shifting ethnic profile. Quite common.; 2) Move nearby to somewhere whiter but still kinda “your area” (Essex is the classic example) – also common. 3) Move across the country to somewhere 99+% white – this is less common because you have no attachments there!

Living near productive people is attractive to other productive people and to parasites.

Bryan offers the straightforward economic solution no one seems to consider:

If the problem is negative externalities, then the usual Pigovian logic applies: Governments should measure these negative externalities — remembering to subtract any positive externalities — then impose an immigration tax of equal magnitude. Anyone who pays the tax gets in.

A tax on work visas would resolve many issues — as would stricter enforcement of ordinary laws:

I keep “gushing” [about the United Arab Emirates] because it’s living proof that “trillion dollar bills on the sidewalk” is not silly blackboard economics. Emirates is a cruise ship the size of a country, where the world’s poorest and richest come together for the betterment of both. The West is demonstrably missing a golden opportunity to enrich their citizens and humanity by tens of trillions of dollars.

The US lacks the will to enforce the rules that would make mass immigration feasible.

Mamdani’s win was largely propelled by the young credentialed precariat

Saturday, November 8th, 2025

End Times by Peter TurchinThe Mamdani Moment, Peter Turchin argues, perfectly illustrates the “credentialed precariat”:

Ten years ago the political landscape in the US was dominated by two parties: one of the “1 percent” (wealth holders) and one of the “10 percent” (credential-holders). Both parties focused on advancing the interests of the ruling class, while ignoring those of the 90 percent. I am, of course, simplifying a lot here; for a more detailed and nuanced explanation see End Times.

In 2016 Donald Trump channeled growing popular immiseration to begin reformatting the Republicans into a right-wing populist — “MAGA” — party. This process is quite incomplete.

Meanwhile, the Democrats had effectively controlled the left-wing populists in their party, by a combination of suppression (think Bernie Sanders) and cooptation (think AOC). As a result, by 2024 the Democratic Party evolved into the sole party of the ruling elites.

[…]

Many pundits commented on the observation that Mamdani enjoyed support among younger voters. Indeed, 78% of the youngest cohort (18-29 years old) voted for him and only 18 for Cuomo, for the Mamdani advantage of 60 points.

[…]

Let’s first look at credential-holders. Astonishingly, the proportion of people, voting in this election, who had at least “some college” experience is 80%. 31% have earned a Bachelor’s and fully 27% hold an advanced degree, with both groups giving Mamdani an advantage of 19 points (57% for Mamdani, 38% for Cuomo).

To tell the truth, I first didn’t believe these numbers. Such concentration of credentialed individuals is amazing. But according to the NYC government survey in 2023, two years ago the proportion of New Yorkers with a bachelor’s degree or higher was 43%, increasing from 33% in 2010. Of the White adults (25 or older) two-thirds completed college. Talk about degree overproduction…

Next, income. Here the relationship is nonlinear. The poorest (earning less than $30,000 per year) and the richest ($300,000 or more) gave more votes to Cuomo, while those in between preferred Mamdani. Thus, the richest 8%, earning $300k or more, preferred Cuomo by 29 points. The problem for Cuomo was that those in the middle category comprised 77% of voters. The biggest degree of preference for Mamdani compared to Cuomo — 20 points — was among those earning $50-99k. This was also the largest group (27% of voters). The next group, $100-199k, were close behind: 18 points for Mamdani.

It may seem strange to call those earning 50-100k “precariat,” but one must take into account that NYC is a very expensive city. The median rent for two-bedroom apartments in New York City increased 15.8% over the past year and is now $5,500 per month (see Zohran’s Park Slope Populists by John Carney), or $66,000 per year. In other words, you will spend two-thirds of your $100,000 income just to keep a roof over your head.

[…]

Still, these numbers provide strong support for the idea that Mamdani’s win was largely propelled by the young credentialed precariat: the youth with college degree, or higher, earning just enough to live on the edge.

How GDP Hides Industrial Decline

Sunday, October 19th, 2025

Patrick Fitzsimmons has been mulling a paradox:

U.S. GDP keeps going up, yet it seems like we make less stuff and that most of the smart people I know work fake jobs. Growing up in the nineties, most of my toys and clothes had tags saying “Made in Hong Kong” or “Made in Vietnam.” But the high-skill, high-tech goods—the washing machine, the car, my computer—were often made in America. Now? From my e-bike to my laptop, from my refrigerator to my mattress, very few goods I own, high-tech or low-tech, were made in the USA.

[…]

Sometimes there are discrepancies between your real-world observations and the data. But this goes far beyond just being a discrepancy: the data is saying the complete opposite of what we see with our own eyes, hear from our acquaintances in the job market, and deduce logically from our knowledge of demographics, technology, industry, and trade. How is this possible? The answer is actually very simple: the data is completely wrong. But you can only figure this out if you go line-by-line into the hundreds of pages of government GDP calculation methodology documentation. Which is exactly what I did.

[…]

I challenge anyone who believes in these statistics to tell me what in the real world happened so that raw tonnage of steel was down, real gross output of steel was flat, usage of inputs was up, but “real value-added” was also up, and up hugely. Nobody can explain these numbers. The BEA cannot—I have asked them! If the raw data still exists, nobody has access to it because it was confidential.

The basic problem is that real value-added calculations only work if there are no quality adjustments and there hasn’t been any substitutions in the inputs. If those assumptions do not hold, you can get wild and nonsensical results. Since those assumptions do not actually hold in the real world, those nonsensical results are mixed into the overall calculation in ways that are impossible to account for, thus making the entire number bogus.

My guess is that what happened with steel production is that factories have moved from using raw iron ore to scrap metal as an input. The scrap metal is actually closer to a final good and requires much less energy to turn into steel. But GDP calculations do not know that scrap metal is closer to a final good. What the GDP calculations see is that materials have become more expensive and that energy inputs are less, so it seems like the steel factories are maintaining output with much less input, and thus value-added is greater. The reality, though, is that the United States is not producing any more steel out of factories, the United States is not producing a greater percentage of the steel value chain than in 1997, and the 125% increase in real value-added is a spurious result that represents neither making more stuff nor making better stuff.

[…]

This is not just my critique: a former deputy chief at the BEA, Professor Doug Meade, has sharply criticized real value-added as a metric. In a 2010 conference paper, he wrote, “more than 60 years after it was first introduced, there is still no fundamental agreement on the meaning of real value added, or its price. Most who use it for the study of productivity loosely describe it as a measure of ‘real output’ although strictly speaking it is not that.” He continues to argue that comparing real value-added between years only works under the conditions of no quality adjustments, no input substitutions due to price changes, and no changes to the terms of trade. If those conditions do not hold, then, he says diplomatically, “it would be unclear what [real value-added] is measuring” Or as economist Thomas Rymes, observing the same issues, put it more directly: “a fictitious measure of output with no meaning.”

[…]

Since nominal value-added is not adjusted by price indexes, it avoids all the problems we discussed with real value-added.

But, once again, the problem with the nominal value-added comparison is that it is not a comparison of actual things—it is a comparison of sales receipts. Thus a given quantity of products that is produced by a bloated cost structure will count as more “GDP” than the same number of products produced by an efficient factory. This is not just a theoretical problem—we know for a fact that the Chinese company BYD produces an equivalent to the Tesla Model 3 for half the price. Thus, $30,000 of manufacturing value-added in the U.S. might represent one car being produced, while for China it might represent two cars, and thus is actually double the output. In general, the China-U.S. dollar exchange rate is not a market rate and thus the conversion does not reflect in any meaningful sense the value of products.

Worse, many U.S. products are more expensive not because they are higher-end and better quality, but because they are protected from competition by tariffs, patents, regulation or national security requirements. For instance, Purism makes an all-in-the-USA phone for $2,000—the phone is no better than a $500 Chinese or South Korean phone, but sells at a premium for the U.S. security market. Others in procurement tell stories of getting quotes for printed circuit boards that cost $5,000 from China but $50,000 in America, thus only government and regulated industries buy American circuit boards. American-made municipal buses can cost three times the price as those made in China, but cities often face rules requiring them to buy American. For a particularly egregious example, thanks to the protections of the Jones Act, American ships cost an astounding ten times as much to build as their foreign counterparts.

[…]

Which is more “output”—one million drones sold for a total of $2 billion dollars, versus one B2 stealth bomber for the same price? A $2,000 custom-made dress for the Met Gala, or one hundred pairs of denim work pants? Nominal value-added comparisons treat them as equivalent.

Nominal value-added cannot tell the difference between a country like 1790s Spain, a manufacturer of luxury goods with inflated nominal prices thanks to New World gold, and 1790s England, a ruthless manufacturer of inexpensive goods that is on its way to world domination. A comparison between countries that simply looks at sales revenues—not at the actual amount of ships, phones, and things produced for that revenue—is simply not a useful comparison.

[…]

When we read a headline saying GDP data shows “car output has increased,” we think the U.S. has made more cars. We then apply our own views as to whether the quality of the car has changed. When we sneak quality into a measure but still call it “output,” we are double-counting and embedding the subjective in the objective, and we lose track of the hard numbers. We are not making more quantity of cars per person like the data says, we are making fewer cars, but with Bluetooth and crumple zones.

[…]

While the BLS provides general information about the quality adjustment process, the specific methodology and the actual decisions are not documented. At the heart of GDP we find this subjective, bureaucratic black box. When we see that “output” of cars has increased since 1997, it is impossible for any commentator to know how that increase in “output” breaks down between actual number of cars, horsepower boosts, safety features, durability improvements, convenience features, blue tooth, power locks, and on and on.

[…]

The point is not that any of these methods is right or wrong. The point is that if you have a half-dozen plausible ways of adjusting for quality, none of which from first principles is more objective than another, and you rule out one method for giving ludicrously low results, and one method for ludicrously high results, and just choose a middle route that feels reasonable, then the result of this adjustment is not an objective measure of output. All you have done is launder vibes into something that has the appearance of an objective number.

You can’t just compare tax rates

Saturday, October 18th, 2025

Brian Albrecht explains why you can’t just compare tax rates between, say, income taxes and tariffs:

Double a tax rate, and you quadruple the deadweight loss. This is a standard result in public finance, and it suggests we should spread our tax burden across many bases rather than concentrate it in one place.

Here’s the intuition. When you impose a small tax, you only kill off marginal transactions—deals that barely made sense in the first place. The buyer was almost indifferent about purchasing, or the worker was almost indifferent about working that extra hour. These marginal transactions don’t create much surplus, so losing them doesn’t cost much.

But as you increase the tax rate, you start killing off transactions with larger and larger surplus. Beyond eliminating the deals that barely made sense, you’re now eliminating deals where both parties really wanted to trade, where there were substantial gains from the exchange. The surplus lost from these inframarginal transactions is much larger.

This is why deadweight loss grows with the square of the tax rate. Double the tax, and you lose transactions that had twice the surplus. The effect multiplies. A 10% tax might eliminate deals that create $1 of surplus each, but a 20% tax eliminates deals worth $1 and deals worth $2. The total loss is 4x, not 2x.

[…]

If you want to compare across markets, you need another basic idea from taxation: deadweight loss depends on elasticities.

[…]

Some supplies are essentially fixed—you can’t create more of them no matter how high the price goes. Other goods can be produced in unlimited quantities at constant cost. Some demands are highly elastic (people readily substitute to alternatives), while others are inelastic (people need the good regardless of price). These elasticities determine how much distortion a given tax rate creates. The tax rate alone tells you nothing.

More elastic demand or supply curves generate larger deadweight losses. The flipside is the classic Ramsey result: tax less elastic goods more heavily.

[…]

Consider taxing a good with a perfectly inelastic supply—say, land in a specific location. The supply curve is vertical. No matter what price landowners receive, they supply the same amount of land because they can’t create more of it. By definition, there is no deadweight loss. The tax doesn’t change behavior.

What happens when we increase the tax rate on land? The tax raises revenue, but it generates no deadweight loss. Landowners absorb the entire tax through lower prices, but the quantity of land traded doesn’t change. There’s no distortion in the allocation of resources. You could tax land at 100%, and the deadweight loss would still be zero.

This demolishes the idea that you can look at tax rates in isolation. There is no nice connection between tax rate and deadweight loss that transcends the specific good being taxed.

Now compare this to a tariff on imported goods, where supply and demand are both elastic. The tariff creates a wedge between what consumers pay and what producers receive. This wedge distorts both consumption decisions (people buy less than they would otherwise) and production decisions (domestic producers make more than they would in an undistorted market). We get the classic deadweight loss triangle.

And it’s not just that imports aren’t perfectly inelastic. They’re very elastic! Estimates vary but one recent paper puts the long-run elasticity at 14, implying a huge deadweight loss.

The formula that deadweight loss increases with the square of the tax rate applies to both taxes. It tells us doubling tariffs with quadruple the deadweight loss. But it tells us nothing about which tax we should increase and the deadweight loss across the two markets. The land tax, even at a 100% rate, might generate zero distortion. The tariff, even at a 2.5% rate, creates real costs because of the huge elasticities. Elasticities matter. You can’t compare tax rates across different bases without accounting for how responsive behavior is to each tax.

[…]

But tariffs are worse than general consumption taxes because they tax only some goods—and imports are a small share of total consumption.

In the US, imports are roughly 10% of consumption. This means tariffs apply to a base that’s one-tenth of a general consumption tax would. When Lott compares a 2.5% tariff to a 40% income tax, he’s ignoring that these rates apply to completely different denominators.

Think of it this way: if you want to raise $100 from a tax that applies to everyone’s $1,000 of consumption, you need a 10% rate. But if you want to raise that same $100 from a tax that only applies to $100 of imports (10% of consumption), you need a 100% rate. The narrow base means you need a much higher rate to raise equivalent revenue.

This logic applies to any narrow excise tax.

25% of working age Brits are out of work

Sunday, October 5th, 2025

In the United Kingdom, one-quarter of the working-age population is currently out of work:

(For comparison, in the United States, a similar statistic finds that only 16.6 percent of people in prime working ages are out of the labor force.) Once someone becomes economically inactive due to health reasons, their chances of ever reentering employment within a year drop to 3.8 percent. Up to 3,000 new people per day are writing off work and being approved for sickness benefits, now totaling around 4 million people.

[…]

A National Health Service (NHS) Confederation report showed that in 2021–22, over 63,000 people went straight from studying to being economically inactive due to long-term sickness. In 2002, mental and behavioral problems were the main condition for 25 percent of claimants. In 2024, that figure rose to 44 percent. More than half of the rise in disability claims since 2019 was due to mental health or behavioral conditions, according to the Institute for Fiscal Studies.

[…]

About 69 percent of those who apply for sickness benefits mention depression, anxiety, or some other kind of mental or behavioral disorder. Mental illness is now being cited by 48 percent of disabled working Brits, making mental health the single biggest problem.

[…]

According to data collected by the TaxPayers’ Alliance, a total of 1.75 million people in England received enhanced personal independence payments (PIP) in April 2025, an increase from 734,136 in January 2019. PIP is just one of many types of social security available to working-age claimants, intended to help them deal with the extra costs of disability. It is available to those in work. However, only one-sixth of PIP recipients are working. Some are receiving these benefits for seemingly minor ailments, including acne, constipation, obesity, “old age,” irritable bowel syndrome, writer’s cramp, and food intolerances.

[…]

In 2019, the number of PIP claimants for autism was 26,256, and by April 2025, this number had jumped to 114,211. For anxiety and depression, it went from 23,647 in 2019, to 110,075 in April 2025. For ADHD, in the same period, it went from 4,233 to 37,339.

[…]

As ludicrous as this sounds, approximately 80 percent of PIP claimants are not in work at all. A person getting incapacity benefits and PIP could be getting 23,899 pounds (roughly $32,250), which is already more than the minimum wage. Someone with children is entitled to even more. When PIP is combined with housing benefits, universal credit, and other offerings, someone could be entitled to 27,354 pounds (roughly $37,000) without paying taxes.

The broad outlines of the news are tiresomely familiar

Tuesday, September 23rd, 2025

People who follow the news often claim to be surprised or even shocked by current events, Bryan Caplan notes, but that’s rarely his reaction:

Sure, I can’t predict the details of the latest happenings. But the broad outlines of the news are tiresomely familiar. Heinous domestic murders. War in the Middle East. Blatant violations of the plain English reading of the Constitution. Chaotic socialist tyrannies in Latin America. Pampered First Worlders blaming their horrible plight (?) on hapless refugees. Civil wars in Africa.

And always, people screaming at each other.

He goes on to list some actual surprises:

The collapse of the Soviet bloc. I expected that all reformism would ultimately be constrained by Soviet tanks. Instead, the Soviet Union let its satellites go, then shattered into 15 separate countries two years later.

9/11. As the vehicular rammings of the mid-2010s show, any motivated midwit can carry out a major terrorist attack. Since major terrorist attacks are very rare, motivated midwits must be in short supply. QED. Yet one far craftier team of terrorists still managed to carry out this world-shaking attack. (Note: I was not surprised that nothing comparable has happened since).

After Obama won, I laughed at a colleague who predicted that complaining about racism in America was finally over. But I was still shocked a few years later when complaining about racism — and renewed “anti-racist” activism — massively multiplied.

In mid-2015, I laughed at the idea that Trump would win the Republican nomination. Once he got the nomination, though, I was only moderately surprised that he won the election.

I was shocked that transgenderism became so common that I personally know multiple people with trans children. Darwinian evolution just tells us less about human sexuality than I imagined.

In 2020, I was not surprised by the emergence of a new, moderately lethal virus. Such things happen a handful of times per century. But I was completely stunned that serious limits on in-person activity lasted more than two weeks in the United States. Indeed, my jaw dropped simply when Disneyland first shut down. I never expected a reasonable policy response, but I counted on ADHD to save us. ADHD did not save us.

I was not surprised that Trump refused to concede the 2020 election. Indeed, one premise of my 2016 election bet was that even if Trump lost, he would not admit it. I was however surprised that he managed to come back from January 6, especially at his age.

I was surprised that Putin tried a full invasion of Ukraine. I thought he would limit himself to annexing de facto independent territory in Donetsk and Luhansk.

I was amazed that AI went from mediocre to excellent so quickly. But not surprised that it’s taking so long for AI to actually replace human workers, even when it conceptually seems easiest.

Trump’s Liberation Day tariffs shocked me. I figured he would limit himself to symbolic outrages, but instead he eagerly terrified the stock market for weeks. While he mostly backed off and the stock market more than fully recovered, there’s almost nothing he could do on foreign trade that would shock me at this point.

How much more does an Indian IT worker make in the US than in India?

Monday, September 22nd, 2025

I recently asked Grok, how much more does an Indian IT worker make in the US than in India?

Absolute Difference: An Indian IT worker earns approximately $116,600 more per year in the US compared to India ($125,000 vs. $8,400).

Multiplier: This represents about 15 times the salary in India (125,000 / 8,400 ? 14.9x).

Wow.

No one improved their reading skills at all

Sunday, September 7th, 2025

The real data on education is more than bad enough, Max Tabarrok says, to merit removing or reforming the Department of Education:

Inflation adjusted spending per pupil tripled since 1970 while reading scores haven’t budged.

There has also been an astounding amount of credential inflation. The amount of time people spend in school has increased by more than three years since the 1970s as more people graduate high school and college, but performance on tests of skill or human capital is completely stagnant.

This suggests, a la Bryan Caplan’s Case against education, that many of these extra years of schooling are actually a socially inefficient zero-sum competition where it pays individually to get the most schooling and come out on top of your peers, but everyone would be better off if people invested less time and money in competing. Hundred billion dollar subsidies to student loans and higher education institutions have exacerbated this zero-sum race for little material gain.

Evidence for this: The NCES ran two rounds of a literacy test, one in 1992 and one in 2003. The overall average score on the test didn’t change (276 vs 275 out of 500), but within every educational attainment group scores dropped massively.

High school dropouts got less literate on average because the highest scoring dropouts in the 90s became the lowest scoring graduates in the 2000s as standards were lowered and more students were pushed through into more education. Literacy scores among Graduate degree holders dropped by 13-17 points in a decade. If a graduate degree cannot even teach you how to read, it’s probably not having large effects on any other more complex forms of human capital.

This means that across this decade of rising educational attainment, no one improved their reading skills at all. Instead, the standards for graduating from each level of schooling were just lowered and people spent more years slogging through high school or college.

Should we have kept the American Empire?

Tuesday, September 2nd, 2025

Should we have kept the American Empire?, Max Tabarrok asks:

Note that the question of whether the US should have relinquished its maximum territorial extent is different than the one facing America in 1865 or the question of expanding American borders today. There, you have to consider the substantial costs of actually conquering territory in war. Holding on to land already conquered is less costly than conquering anew.

[…]

The first thing to notice when considering this question is that America did not actually give up all of its imperial conquests. Hawaii, Puerto Rico, the Virgin Islands, a smattering of pacific islands, Alaska, and arguably even much of the American Southwest are spoils of conquest or purchase.

No one seriously considers giving up any of the pieces of our imperial history that we kept. The Hawaiian independence movement is perhaps the most popular, but that sets a low upper bound. This acceptance of the pieces of empire we retained suggests that if we had kept more of our 1918 peak territory, people would accept those additional pieces just as easily today.

Reluctance to give up what we kept isn’t just status quo bias. The economic performance of the states and territories still within the US compared to the nations we once controlled but are independent today is evidence that American annexation has large positive effects.

[…]

Integration under the same national umbrella seems like about the only way to sustain and spread free trade and immigration. The US can’t even manage it with Canada. The principal domestic supporters of Philippine independence, for example, were American farmers who didn’t want to face competition from tariff-free Filipino sugar, and nativists who didn’t want immigration from “alien races.”

A final general argument is, perhaps surprisingly, political legitimacy. The nations that America was closest to annexing are not only economic underperformers, they also tend to be undemocratic and authoritarian. Recently, Panama and the Dominican Republic are probably exceptions here with relatively successful and stable governance.

We really don’t know what it would be like to live in a red city in a red state

Monday, August 18th, 2025

When his best friend in Austin quips, “It’s great living in a blue city in a red state,” Bryan Caplan is tempted to reply, “ We really don’t know what it would be like to live in a red city in a red state — or even a red city in a blue state.”

Why? Because they barely exist. Zero cities with over one million people currently have Republican mayors.

From the standpoint of the textbook Median Voter Model, this is awfully puzzling. Even if urbanites are extremely left-wing, you would expect urban Republicans to move sharply left to accommodate them. Once they do so, the standard prediction is that Republicans will win half the time. But plainly they don’t.

One possibility is that Republican politicians are too stubbornly ideological to moderate. But the idea that virtually no one in the Republican Party is power-hungry enough to tell urban voters what they want to hear is deeply implausible.

The better explanation, as I’ve explained before, is that urban voters have party preferences as well as policy preferences. They don’t just want left-wing policies; they want left-wing policies delivered by the Democrats.

They would become the middle class

Sunday, August 17th, 2025

In Western Europe, Peter Frost notes, a consensus emerged on the need to execute violent males so that law-abiding people could live in peace:

By the Late Middle Ages, courts were condemning to death between 0.5 and 1% of all men in each generation, with perhaps just as many dying at the scene of the crime or in prison while awaiting trial. The pool of violent men dried up until most murders occurred under conditions of jealousy, intoxication or extreme stress. As a result, the homicide rate fell from 20–40 homicides per 100,000 in the Late Middle Ages to 0.5–1 per 100,000 in the mid-20th century.

People could now get ahead through trade and work, rather than through theft and plunder. This new, pacified environment favored the growth of the market economy and the success of those who possessed the necessary skills, especially literacy, numeracy and budgeting. They would become the middle class.

The North Sea and the Baltic form the core zone of certain tendencies

Thursday, August 14th, 2025

DNA from human remains is showing us how different populations have evolved over time, Peter Frost explains, not only during prehistory but also well into recorded history:

This evolution has affected a wide range of mental and behavioral traits: cognitive ability, time preference, propensity for violence, monotony avoidance, rule following and empathy, among others.

[…]

Why did the North Sea overtake the Mediterranean in international trade? Certainly, the latter region was adversely affected by the Arab conquests of the Middle East and North Africa. But the economic decline began much earlier. Shipwrecks on the bottom of the Mediterranean have been dated overwhelmingly to the time between the first century BC and the first century AD. Silver mining in Spain and Cyprus likewise fell sharply after the first century AD, as shown by lead contamination of Greenland’s ice sheet.

This decline occurred not only before the Arab conquests of the seventh and eighth centuries, but also before the barbarian invasions of the fourth and fifth and the Imperial Crisis of the third. And it seems inconsistent with modern economic thinking: bigger markets should create economies of scale, as well as a better match between supply and demand. So what caused things to go wrong?

[…]

One cause was the low level of social trust. People trusted only their close friends and relatives, keeping everyone else at arm’s length. As a result, economic activity was bottled up within family networks, the major exception being physical marketplaces where buyer and seller could meet face to face. Because the market principle remained trapped within small pockets of space and time, it could not generalize to all transactions in Roman society. An economy of markets never evolved into a true market economy.

[…]

One [other cause] was a deterioration of physical health, as indicated by the length of long bones belonging to over 10,000 adult men and women born between 500 BC and 750 AD. The data show a steady decrease from the second century BC, reaching a low point in the second half of the first century AD, followed by a slow recovery and then a dramatic recovery from the fifth century AD.

[…]

The study’s authors concluded that the Romans created not only an integrated Mediterranean economy but also “the first integrated disease regime”.

[…]

The other cause was a decrease in average cognitive ability. Fewer people could master the skills of numeracy, literacy and budgeting that are so essential to economic activity.

This decline was driven by an uncoupling of reproductive success from economic success—as I argued in a previous article. The wealthy were no longer using their wealth to bring children into the world. A rich man might prefer to leave his wife for a younger woman of low social status, often adopting her children. Or he might never marry. The resulting fall in cognitive ability can be seen in DNA retrieved from the human remains of that period.

The North Sea and the Baltic form the core zone of certain tendencies that, for at least a millennium, have prevailed north and west of a line running from Trieste to St. Petersburg, i.e., the “Hajnal line.” These are tendencies toward individualism, the nuclear family, late marriage and solitary living, as well as a greater willingness to trust strangers and form bonds of impersonal prosociality.

Such tendencies didn’t come into being with the market economy — they arose long before for an unrelated reason. But they did provide the best behavioral conditions for a market economy once the possibility of creating one emerged.
