The result is that even though today’s young adults, and graduates in particular, are over-represented in the top quartile of the earnings distribution, they are also far more likely to be at the bottom than the top for earnings relative to reasonable expectations. In both the UK and US, even though only 10 percent of graduates are in the lowest earnings quartile, one in three is in the bottom bracket for earnings relative to expectations.
Here is more from John Burn-Murdoch at the FT.

Everyone knows the Luddites smashed looms. What is less appreciated is that the loom was the first serious programmable device — the direct ancestor of the computer. Thus, the Luddites weren’t just the first to resist automation. They were in some ways the first to attack AI.
The Jacquard loom, introduced in France circa 1805, used a chain of punched cards to control which threads were raised for each pass of the shuttle. The ability to change the pattern of the loom’s weave by simply changing cards was an important conceptual precursor to computer programming. Babbage borrowed the idea directly for the Analytical Engine in the 1830s.
The Luddites lost–they were violently suppressed by the UK military–but more generally they lost because programmable looms brought patterned clothes to the masses.
Prior to its invention, the creation of complex patterns required skilled and labour-intensive manual labour, often involving large teams of weavers. With the Jacquard loom, a single operator could control the machine and produce intricate designs with relative ease.
This innovation greatly increased the speed and efficiency of textile production. It also opened up new possibilities for creativity and design, as the loom enabled the production of intricate patterns that were previously unattainable. The Jacquard loom contributed to the democratization of textile manufacturing, making intricate fabrics accessible to a wider audience
By the time Jacquard died in 1834, thousands of his looms were operating in Manchester, an epi-center of the Luddites riots. Moreover, just over 100 years later, Manchester birthed the Manchester Baby and the Manchester Mark 1, the first electronic stored-program computer. And who was hired to program the latter? None other than Alan Turing.
Ada Lovelace had foretold it all beautifully: “the Analytical Engine weaves algebraical patterns just as the Jacquard-loom weaves flowers and leaves.”
Addendum: I thank Claude for assistance on this post.

This paper compares agentic AI systems and human economists performing the same causal inference tasks. AI systems and humans generally obtain similar median causal effect estimates. While there is substantial dispersion of estimates across model instances, the human distributions of estimates have wider tails. Using AI models as reviewers to compare and rank “submissions,” the following ranking emerges regardless of reviewer model: (1) Codex GPT-5.4, (2) Codex GPT-5.3-Codex, (3) Claude Code Opus 4.6, and (4) Human Researchers. These findings suggest that agentic AI systems will allow us to scale empirical research in economics.
I enjoy the name of the author, namely Serafin Grundl. Here is the paper, via Ethan Mollick. You could interpret these results as showing the AIs have fewer hallucinations. And just to reiterate a key point from the paper:
The second part of this paper is an AI review tournament in which “submissions” (codes and write-ups) from humans and the AI models are compared and ranked against each other. The reviewers are the following AI models: Gemini 3.1 Pro Preview, Opus 4.6 and GPT-5.4. For each review the reviewer is asked to write a report comparing four submissions (human, Opus 4.6, GPT-5.3-Codex, GPT-5.4). Each reviewer model writes comparison reports for the same 300 comparison groups. The average rankings are strikingly similar across reviewer models: (1) Codex GPT-5.4, (2) Codex GPT-5.3-Codex, (3) Claude Code Opus 4.6, and 2(4) Human Researchers.
Who comes in last? Hi people!

Zimbabwe, often considered an economic basket-case because of its history of farm seizures and hyperinflation, is enjoying an idiosyncratic boom. High prices for the metal and other commodities have led to a surge of cash through its highly informal economy. They have made it easier for authorities to stop printing money and meddling in currency markets; inflation is at its lowest in about 30 years. The IMF has repeatedly revised upwards estimates for economic growth, most recently to at least 7.5% for 2025, almost double the African average…
Gold is not the only source of growth. The current tobacco crop will be the largest on record. Lithium, chrome and platinum miners, many of them Chinese, have raised production. Zimbabwe’s diaspora, mainly in South Africa, sent back $2.5bn last year. So overall demand is higher than ever, says a banker.
Here is more from The Economist. We are told that the private vault sector is booming too.

1. Sindarov profile. And: “I know this GM who made 2600 at 19 without reading a chess book in his life.” And Magnus on Sindarov vs. Gukesh.
2. Inflation-adjusted book prices over time.
3. On the Amanat Iran book and its excellence.
4. More on the wet market hypothesis. We should all be uncertain, but it is mood affiliation (with conspiracy theorizing, for one thing) to be convinced of Lab Leak. It is contributing to negative emotional contagion.
5. Review of the new Knausgaard series. By Max Norman: “(I’d rather read Knausgaard on defecation than predestination, let alone whether machines can think or trees can feel.)”‘
6. AI and the arts, a short Instagram video.
7. AI and the pancreatic vaccine. More testing is needed, but there is a reasonable chance that we have a good treatment for pancreatic cancer, and AI was instrumental in that. It is mRNA as well, so a double burn on the haters.
