My name is Josh Neuman, and I’m writing from Buenos Aires, Argentina where Peter Thiel’s move is all over the news here. He lives in [redacted], only a xx minute drive from my own apartment in Recoleta.

I want to pitch a piece…arguing that Thiel is right to be in Argentina, but wrong about why. The libertarian revolution he thinks he’s found simply doesn’t exist in the way it’s being advertised in the international press. Milei has accomplished some real things since December 2023, such as lower inflation and a fiscal surplus, in part underwritten by Washington. But the effect of many of his policies has been exaggerated by both supporters and opponents alike, with widespread pessimism across all parts of society.

Much of the Argentine status quo he sought to abolish remains intact, such as retenciones on agricultural exports, union control over the labor market, while many of his reforms have had little impact beyond Buenos Aires, particularly in the northern provinces still dominated by entrenched Peronista governors. Distrust of the peso remains high, while much of the economy is still black market, with the informal sector still being around 40-50% of employment. The lines outside the Spanish and Italian consulates of Argentines reclaiming European citizenship are as long as ever, while major business figures like Marcos Galperin still live in neighboring Uruguay. Peronism as I’m sure you know has mutated several times throughout its history to each contemporary crisis, and will prove far more durable in the long run as a social identity as much as a political machine.

Argentina’s retenciones are export taxes levied on agricultural commodities like soybeans, wheat, and corn at the point of sale, before producers receive any income, which goes towards the government, and is how Argentine governments (especially Peronista ones) have historically paid for the country’s welfare state. The system also functions as a price mechanism because by taxing exports, the government keeps more supply in the domestic market, suppressing local food prices. The retenciones are deeply unpopular among the crop producers and landowners, and Milei campaigned on eliminating them. He has largely kept them, because he needs the revenue to maintain the fiscal surplus that is the centerpiece of his program.

But I think there’s a deeper cultural dynamic that I’m not sure Thiel understands. Argentine youth aspire much more towards la dolce vita than towards Weber’s protestant work ethic. They essentially want their country to be like Spain or Italy, with a chill work-life balance,  high leisure and consumption, underwritten by a generous welfare state, even if that model is becoming fiscally and demographically unsustainable in Europe. I think it’s a completely reasonable and in many ways admirable goal, but companies like Paypal, Palantir, and Facebook did not come out of Spain or Italy.

Among my Argentine peers, I hardly meet anyone who aspires to move to the United States. When I tell friends that the American economy has been growing at twice the rate of Europe in recent years, I am met with genuine disbelief. I think Thiel may have been captivated by a small teleological elite in Milei’s inner circle who do not necessarily represent the country they govern. The average Argentine who voted for Milei did not vote for Austrian economics or for a libertarian revolution. They voted out of exhaustion with Peronism, as many of Milei’s supporters were former Peronists themselves, much as many Trump supporters in the American Rust Belt were former Obama voters.

Argentina’s genuine case for Thiel rests on things that have nothing to do with Milei: a younger demographic than Europe, world-class human capital, abundant lithium and rare earths, and geographic isolation from great power conflict. He may be right for entirely the wrong reasons, on a longer timeline than he expects, through considerably more turbulence than the current narrative suggests. Argentina’s laid-back mentality is precisely what makes it exciting to foreigners. But as a project for civilizational renewal? Unless you’re talking about surviving a nuclear war, absolutely not.

I’m an Argentine-American master’s student in international relations at Universidad Torcuato Di Tella…

Overall, the Western Hemisphere now produces more oil than the Middle East did before the crisis. Canada is the world’s fourth-largest oil producer. Brazil produces four times as much oil as Venezuela; and in Guyana, where production began only seven years ago, output almost equals Venezuela’s. In Argentina’s Vaca Muerta region, shale oil production has grown sixfold since 2020. The current disruption will propel more oil and gas investment in the Western Hemisphere and Africa.

Here is more from Daniel Yergin in the WSJ.

When during the meetings the Americans offered that at most they could convert 15 percent of U.S. auto plants to military production, Beaverbrook replies that 100 percent of British automobile factories had been converted, and encouraged Roosevelt to aim higher.  He did, and on January 1 he ordered U.S. auto production halted by late Februrary.  Within weeks the dearth of new cars became moot when rubber, 90 percent of which came from Malaya and Indonesia, was rationed.  The U.S. had no synthetic rubber factories to make up the shortfall.  Americans soon learned what Britons had long known: without a spare tire or three stashed in the garage, the family car had a very limited range.  Passage by rail — where for fifty years the Pullmans had been Americans’ preferred means of conveyance — was soon limited to troops and businessmen on official war business.  And then the airlines — their routes and the national fleet of 434 aircraft — were commandeered.  By spring, gasoline ratioining, as a mean to preserve rubber more than oil, dribbed on to the Eastern Seaboard and in the following year spread nationwide, guaranteeing that Americans in the heartland could no longer take their vacations at east or west coast beaches even if their bald tires could carry them there.  That proved okay with most because by summer, oil and bilge tar and decomposing bodies — the U-boats’ harvest — regularly washed up onto America’s eastern beaches.

That is all from the excellent The Last Lion: Winston Spencer Churchill: Defender of the Realm, 1940-1965.  As I’ve said before, you can always keep on reading books about World War II and you will continue to learn interesting and important things.

]]> That is the topic of my latest Free Press column.  Here is one excerpt:

The present and also future of mankind is a world where reasonably high levels of self-discipline are needed to do well. The journalist Daniel Akst pointed this out in his 2011 book Temptation: Finding Self-Control in an Age of Excess, and we are now living it full force.

I would rather cope with that world than face the full nanny state, backed by modern, AI-intensified surveillance techniques to boot. Concentrating more power in political authorities hardly solves the basic problem. If marijuana and sports gambling can manipulate weak individuals, so can unscrupulous political leaders. A greater realization of individual weakness does not translate into a case for more government action; if anything, it suggests the opposite. Better to allow our social problems to fester in a more decentralized fashion, rather than reinforce our social pathologies through a manipulative and dysfunctional leader at the very top.

In the longer term, we may need to look to medications, such as GLP-1 drugs and their offshoots, which seem to curb some forms of addictive behavior beyond the appetite for food. Alternatively, some individuals may choose self-surveillance, with self-imposed penalties for bad or addictive behavior. Perhaps your AI, or a hired third party, docks your bank account every time you puff on a joint. I am not convinced such services ever will become popular, but that should be taken seriously as an indicator of what people really want to do. We can at least give them better options for self-constraint. If they rarely choose such options, then perhaps for many of those people, marijuana consumption is not a matter of weakness but a very well-established preference, whether we like it or not…

In short, it is time to realize that paternalism is far less workable than in times past. Our government does not have the credibility, the control over information, or the control over our lives to pull it off.

I do understand that is in some significant ways bad news, as voluntary choice is overwhelming some of us with bad outcomes.

My response is to start by accepting some steps backward, holding paternalist tyranny at bay, and hoping some longer-run cultural and technological adjustments will make this all more workable.

If you have a better solution, I would love to hear it.

Large language models (LLMs) are increasingly promoted as educational tutors, yet most evaluations focus on domains with a single ground truth. Many disciplines, however, hinge on judgment: reasoning, weighing ambiguity, and reaching defensible conclusions. Law provides a sharp test. We conducted a blinded evaluation of short-answer tutoring in contracts courses with sixteen U.S. law professors. Participants created 40 representative questions, wrote answers, and judged 2,918 anonymized comparisons between human and LLM responses. Professors rated LLMs far higher than their peers (average win rate = 75.33%), with models performing similarly to the best instructor. LLM responses were also rarely flagged as harmful (3.53%, vs 12.06% for professors). Preferences for LLM answers were consistent across evaluators and reflected shared professional standards. Our evaluation can be reliably extended to additional models by employing a separate LLM as a judge, rendering expert agreements an effective, scalable method to evaluate AI tutors in judgment-rich domains.

“far”.  That is from a new paper by Alejandro Salinas, et.al.  Via Andrew Curran.  And via John Chamberlain:

Artificial intelligence (AI) and large language models (LLMs) tools are capable of mass-producing academic finance papers that are nearly indistinguishable from human-authored research, according to a new study published in the Journal of Economic Literature.

C’mon people, get ready.  I know it is difficult to admit when your human capital has been devalued, but that time is upon us.  In particular, being prolific is no longer such a comparative advantage in academia.  You might run to the “but I know what questions to ask” cope, but I implore you to solve for the equilibrium.  What is the equilibrium wage for merely asking questions?

Of course academic life and projects will continue, but the real rewards will go to people doing new, innovative, and hitherto impossible projects with AI.

According to Feynman’s approach, in this context, people should try a different restaurant each night until they find one that exceeds a particular threshold that reflects a desired quality.

In Feynman’s equations this threshold is not fixed. Instead it declines more and more rapidly as the number of days left in the city reduces. In other words, as the days go by there is increasingly less motivation to hunt for an amazing dining spot, because the time you will have to enjoy it has decreased.

“The thresholds are being guided by the best thing you might be able to find if you kept looking,” said Griffiths. “If you have a long time to look, finding something amazing has a lot of value because you can go back many times.”

Feynman’s approach assumed there is equal possibility of finding any restaurant within a fixed range of quality. However the researchers also explored other scenarios.

“We showed that if the distribution of restaurants varies, then the strategy you should follow will change too,” said Griffiths.

Here is the full story, and here is the PNAS article.  I think of that as a pretty pessimistic approach to the problem.  In most locales you should be able to find lots of very good restaurants, so if you find a quality place early on you do not return to it, rather you keep looking for more, in fact feeling emboldened by your early success.  Maybe this algorithm applies to Cuba?

In 2019, there were about 150,000 people working in autism therapy. Six years later, there were 654,000—more than the number of people who work in mining and logging, or telecommunications, or at the US Postal Service.

That is from Derek Thompson.  And here is the seven-minute nap story from the NYT:

At Compleat Kidz, a fast-growing chain of autism clinics based in North Carolina, the policy is firm: Naps cannot be longer than seven minutes before children are awakened to resume therapy. The company says this is necessary to prevent fraud since clinics can be paid only when children are awake and getting services. But it also allows the clinic to bill insurers or Medicaid for more hours.

I do not even need to say “model this.”

This paper examines how expanding the legal definition of sexual assault affects fertility and sexual behavior, using a panel of European countries. I find that switching to tacit consent-based legislation reduces fertility by about 4% relative to the mean. This effect is driven by a decrease in couple formation and an increase in abortion rates. Supporting evidence is consistent with a behavioral channel in which more risk-averse individuals withdraw from dating and partner markets following the reform, altering the composition of those who remain active toward a pool that is less precautionary. Consistent with this compositional shift, contraceptive use rises among younger women but declines among older age groups, while condom use falls among young men. Finally, an analysis of appeals court verdicts in Sweden following the adoption of consent-based legislation shows a decline in unanimous guilty verdicts, indicating challenges in assessing tacit consent. These results are consistent with a simple framework in which heterogeneity in risk perceptions and precautionary behavior in dating and partner markets, including reduced participation by some individuals, helps explain the observed decline in fertility following the reform.

Several important questions — such as the possibility of debt-rollover without primary surpluses — turn on whether the present value of the aggregate endowment is finite, i.e., whether the economic growth rate under the “risk-neutral” measure, lies below the risk-free rate. It is tempting to argue that the endowment must be finitely valued, since there exist finitely-valued, non-depreciating assets whose cash flows are cointegrated with aggregate output. This paper shows why this argument is incorrect. A remarkable historical episode in which French government bonds were indexed to aggregate growth allows direct measurement of the risk-adjusted growth rate, which is found to exceed the risk-free rate.

That is from a new NBER working paper by Stavros Panageas.
