Rachel Glennerster calls for reforming foreign aid
Aid agencies already try to cover too many countries and sectors, incurring high costs to set up small programs. Aid projects are far too complicated, resembling a Christmas tree weighed down with everyone’s pet cause. With less money (and in the US, very few staff), now is the time to radically simplify. By choosing a few highly cost-effective interventions and doing them at large scale in multiple countries, we would ensure
- aid funds are spent on highly effective projects;
- we benefit from the substantial economies of scale seen in development;
- a much higher proportion of aid money goes to recipient countries, with less spent on consultants; and
- politicians and the public can more easily understand what aid is being spent on, helping build support for aid.
The entire piece is excellent.
We need more elitism
Even though the elites themselves are highly imperfect. That is the theme of my latest FP column. Excerpt:
Very often when people complain about “the elites,” they are not looking in a sufficiently elitist direction.
A prime example: It is true during the pandemic that the CDC and other parts of the government gave us the impression that the vaccines would stop or significantly halt transmission of the coronavirus. The vaccines may have limited transmission to some partial degree by decreasing viral load, but mostly this was a misrepresentation, perhaps motivated by a desire to get everyone to take the vaccines. Yet the vaccine scientists—the real elites here—were far more qualified in their research papers and they expressed a more agnostic opinion. The real elites were not far from the truth.
You might worry, as I do, that so many scientists in the United States have affiliations with the Democratic Party. As an independent, this does induce me to take many of their policy prescriptions with a grain of salt. They might be too influenced by NPR and The New York Times, and more likely to favor government action than more decentralized or market-based solutions. Still, that does not give me reason to dismiss their more scientific conclusions. If I am going to differ from those, I need better science on my side, and I need to be able to show it.
A lot of people do not want to admit it, but when it comes to the Covid-19 pandemic the elites, by and large, actually got a lot right. Most importantly, the people who got vaccinated fared much better than the people who did not. We also got a vaccine in record time, against most expectations. Operation Warp Speed was a success. Long Covid did turn out to be a real thing. Low personal mobility levels meant that often “lockdowns” were not the real issue. Most of that economic activity was going away in any case. Most states should have ended the lockdowns sooner, but they mattered less than many critics have suggested. Furthermore, in contrast to what many were predicting, those restrictions on our liberty proved entirely temporary.

Who needs a UBI?
CDPAP’s enrollment, workforce and total costs ballooned after the state relaxed eligibility rules in 2015. The number of people receiving care through the program surged from just under 20,000 in 2016 to almost 248,000 last year. New York state Medicaid spending on CDPAP in the last five years has more than tripled to about $9.1 billion.
New York needs to make changes to the program, which Hochul called “wildly expensive.”
…Jobs in home health make up an increasingly large share of the city and state’s overall economy. Between 2014 and 2024, home health aide jobs went from comprising 6% of New York City’s total private-sector jobs to 12%, according to Bill Hammond, the senior fellow for health policy at the Empire Center for Public Policy, a fiscally conservative think tank.
I am not sure all of these numbers fit together, and am not sure that the actual percentage of private sector jobs is 12 percent. Nonetheless, the growth here seems quite rapid. Here is more from Laura Nahmias at Bloomberg.

Congratulations to the 2025 John Bates Clark Medalist Stefanie Stantcheva
Awesome choice, she is one of my favorite economists, and she is also a super-nice person. Here is the report and list of winners, here are previous mentions on MR.
My debate with Dani Rodrik about tariffs and free trade
This occurred in Knoxville, you can watch it here. Lots of fun, and p.s. I am more of a free trader than he is. We did have some disagreements.
Is this a lot or a little?
“The Effect of Deactivating Facebook and Instagram on Users’ Emotional State” — by Hunt Alcott, et.al.
We estimate the effect of social media deactivation on users’ emotional state in two large randomized experiments before the 2020 U.S. election. People who deactivated Facebook for the six weeks before the election reported a 0.060 standard deviation improvement in an index of happiness, depression, and anxiety, relative to controls who deactivated for just the first of those six weeks. People who deactivated Instagram for those six weeks reported a 0.041 standard deviation improvement relative to controls. Exploratory analysis suggests the Facebook effect is driven by people over 35, while the Instagram effect is driven by women under 25.
What is wrong with the simple model that Facebook and Instagram allow you to achieve some very practical objectives, such as staying in touch with friends or expressing your opinions, at the cost of only a very modest annoyance (which to be clear existed in earlier modes of communication as well)?
Here is also a new paper on phone app usage in the classroom, by Billur Aksoy, Lester R. Lusher, and Scott E. Carrell:
Phone usage in the classroom has been linked to worsened academic outcomes. We present findings from a field experiment conducted at a large public university in partnership with an app marketed as a soft commitment device that provides incentives to reduce phone use in the classroom. We find that app usage led to improvements in classroom focus, attendance, and overall academic satisfaction. Analysis of time spent outside the classroom suggests a potential substitution effect: students using the app allocated less time to study, particularly on campus. Overall, though statistically insignificant, we find improvements in transcript grades associated with app usage.
Again NBER. I just do not see the compelling case for the apocalyptic interpretations here.
Long-Run Effects of Trade Wars
This short note shows that accounting for capital adjustment is critical when analyzing the long-run effects of trade wars on real wages and consumption. The reason is that trade wars increase the relative price between investment goods and labor by taxing imported investment goods and their inputs. This price shift depresses capital demand, shrinks the long-run capital stock, and pushes down consumption and real wages compared to scenarios when capital is fixed. We illustrate this mechanism by studying recent US tariffs using a dynamic quantitative trade model. When the capital stock is allowed to adjust, long-run consumption and wage responses are both larger and more negative. With capital adjustment, U.S. consumption can fall by 2.6%, compared to 0.6% when capital is held fixed, as in a static model. That is, capital stock adjustment emerges as a dominant driver of long-run outcomes, more important than the standard mechanisms from static trade models — terms-of-trade effects and misallocation of production across countries.
That is from a new NBER working paper by David Baqaee and Hannes Malmberg. Bravo to the authors for producing this result so quickly. And…as a side note…other forms of taxing capital can be bad too! Really. A number of people have spent the last twenty years tying themselves into knots on this question.

1. I find this illustrative, and also very, very naive. Here is a related query. I think this crowd is bad at modeling social systems and macro systems more generally. That is an intrinsically thing to do, but I would keep that in mind when reading “rationalist” analyses.

5. “Texas schools nix lesson over Virginia state flag’s exposed breast. The Roman goddess Virtus has been on the state flag since 1861, but the banner has only featured her bare breast since the early 20th century.” And: “A case of early 20th-century gender confusion led to the breast baring in the first place. In 1901, Secretary of the Commonwealth D.Q. Eggleston complained that Virtus “looked more like a man than a woman and wanted to correct it. He instructed designers to add the breast to clarify her sex,” the Virginian-Pilot reported in a 2023 deep dive into how Virginia wound up with the only state flag boasting an exposed nipple.”
6. Ethan Mollick on AGI. And resistance to the term AGI and its attainment. A good piece, with a cameo by Duchamp.
“Growth is getting harder to find, not ideas”
Here is the thread, here is the paper:
Relatively flat US output growth versus rising numbers of US researchers is often interpreted as evidence that “ideas are getting harder to find.” We build a new 46-year panel tracking the universe of U.S. firms’ patenting to investigate the micro underpinnings of this claim, separately examining the relationships between research inputs and ideas (patents) versus ideas and growth. Over our sample period, we find that researchers’ patenting productivity is increasing, there is little evidence of any secular decline in high-quality patenting common to all firms, and the link between patents and growth is present, differs by type of idea, and is fairly stable. On the other hand, we find strong evidence of secular decreases in output unrelated to patenting, suggesting an important role for other factors. Together, these results invite renewed empirical and theoretical attention to the impact of ideas on growth. To that end, our patent-firm bridge, which will be available to researchers with approved access, is used to produce new, public-use statistics on the Business Dynamics of Patenting Firms (BDS-PF).

It’s happening, UAE edition
The United Arab Emirates aims to use AI to help write new legislation and review and amend existing laws, in the Gulf state’s most radical attempt to harness a technology into which it has poured billions.
The plan for what state media called “AI-driven regulation” goes further than anything seen elsewhere, AI researchers said, while noting that details were scant. Other governments are trying to use AI to become more efficient, from summarising bills to improving public service delivery, but not to actively suggest changes to current laws by crunching government and legal data.
“This new legislative system, powered by artificial intelligence, will change how we create laws, making the process faster and more precise,” said Sheikh Mohammad bin Rashid Al Maktoum, the Dubai ruler and UAE vice-president, quoted by state media. Ministers last week approved the creation of a new cabinet unit, the Regulatory Intelligence Office, to oversee the legislative AI push.

The 1982 IHS seminar I attended
It was a week long, in Hartford, CT, sponsored by the Institute for Humane Studies. The four faculty were:
Robert Nozick
Israel Kirzner
John Gray
Ronald Max Hartwell
Those were the only faculty, for one week — pretty amazing! Libertarianism and classical liberalism quite simply had much higher intellectual status in those days. You could not assemble a comparable group of lecturers today.
I thank David Price for jogging my memory here.

Our non-eggcellent regulations
Germany, Italy, Poland and Sweden are among the nations the U.S. Department of Agriculture approached to address the shortage brought on by a bird flu outbreak, according to European industry groups.
But supplying Americans with eggs would be complicated for foreign producers — but not because of political tensions over the myriad import tariffs President Donald Trump has imposed or threatened to impose on his nation’s top trading partners.
Even if they were eager to share, European countries don’t have many surplus eggs because of their own avian flu outbreaks and the growing domestic demand ahead of Easter.
One of the biggest obstacles, however, is the approach the United States takes to preventing salmonella contamination. U.S. food safety regulations require fresh eggs to be sanitized and refrigerated before they reach shoppers; in the European Union, safety standards call for Grade A eggs to be sold unwashed and without extended chilling.
Here is the full story, via Rich Dewey. So no, American scientists will not be moving to Europe — their eggs are too dangerous. And yes it is Germany too:
It is common in parts of Europe, for example, for consumers to buy eggs that still have feathers and chicken poop stuck to them.
Here is Patrick Collison, comparing the virtues of America to the virtues of Europe. I do not mind that he left out the chicken poop, for me it is a sign of authenticity. As for eggs, the best ones I ever had were in Chile.
